the clutch is one of many essential components of a motorcycle top rated by pulling or releasing the clutch lever with the left hand before going into the details on working of a clutch let's see how it is assembled in motorcycles power from the engine is converted to Rotary mower the crankshaft as shown is power has been transferred to clutch housing clutch assembly transfers power to the input shaft of the gearbox the power's been transferred to the output shaft and eventually to the rear wheel of a motorcycle the clutch assembly itself is a combination of several parts sister pressure plate held in place by using several Springs and screws plate presses against the clutch pack the clutch pack consists of several steel and friction plates placed in alternate positions clutch basket and the inner Hub are assembled with their axes aligned to the input shaft of the gearbox now let's understand how a clutch works the clutch basket free Wheels with respect Fox the engine power will spin the clutch basket but it will not transfer any power to the gearbox however the inner Hub is connected input shaft of the gearbox we spend this inner Hub then it will also spend the gearbox input shaft let's take a hypothetical connected with teeth on its internal and external portion that can interlock with both the clutch basket and the inner Hub if we insert this hypothetical connector between the clutch basket in the inner Hub then we can spin both of these at once in the engine power reaches the gearbox please remove this hypothetical connector basket and inner Hub will be Independence again and the engine power is disconnected but there is a problem in using this connector the connector is removed the inner Hub spins due to inertia of the motor wheel and the outer basket spins due to engine power this is why these two components start spinning at different speeds in order to interlock with both of these non-synchronous spending components the hypothetical connector will have to spend at two different speeds at the same time which is impossible for example if it matches the inner Hub speed then interlocking this connector with the outer basket will be either impossible or too difficult to eliminate this problem the clutch pack is used in place of this hypothetical connector unlike a hypothetical connector the clutch pack is a combination of separate circular plates let's take any two adjacent plates from the clutch pack one of them is a friction plate and the other is a steel the friction plate has teeth on the outer circumference which always interlocks with a clutch basket and can slide sideways along this clutch basket the plate spins with the clutch Bass doesn't affect the inner hub the steel plate has teeth in its inner portion which always interlocks with the grooves in the inner Hub and can slide sideways along this hub spins with the inner Hub but doesn't affect the outer basket these plates can slide sideways we can press them together actually increasing friction so that both of them start acting like a single unit like our hypothetical connector with this Arrangement if we outer basket the inner Hub will also this will eventually transfer power from the engine to the gearbox even if the plates are spinning it different RPM at first the gradual increase in friction between them will eventually synchronize them if we release the pressure the two plates become independent disconnect the inner Hub with the clutch and the engine power is disconnected several other plates are added to increase strength and surface area now let's understand how pressure on these plates are changed while riding a motorcycle we use the pressure plate for this purpose it has ducted attachments where set of Springs can fit in a set of retainer bolts are screwed to the inner Hub this causes the spring to compress and apply force on the clutch pack resulting insufficient friction between the plates we can release the pressure on the clutch pack by pushing the pressure plate outwards we can control this pressure pulling or releasing the clutch lever as the clutch lever is pulled or released a cable or hydraulic system rotates and actuator arm as shown in the animation disarm presses against the pushrod towards the clutch this rod goes through a duct inside the input shaft and pushes the pressure plate releasing the pressure on the clutch pack when the clutch lever is released again apply pressure to the clutch pack as shown in the animation

motorcycles of today are the true marvels of engineering basic model of inner parts of a tip cycle is shown here we will explain the basic function of each of these parts in a motorcycle let's begin from how a motorcycle engine starts all motorcycles have either a Kickstarter or a self-starter or both starter mechanism is simple yet interesting as the kickstarter livre is descended a helical spline forces the gear to slide and engage with a freewheeling gear on the main shaft as the leaver is descended further the gear spins on its axis and transfer the power to the clutch Hub the clutch Hub transfers the power to the crankshaft and eventually to the engine battery powered motor provides initial spin to the engine once the engine is started the starter motor has to be disengaged from the crankshaft to prevent damage due to excessive speed achieved by using a one-way clutch shown here is it a roller type one-way clutch it has an odor race and an inner race with small rollers as the starter motor spins the outer race in One Direction the rollers get trapped between the surfaces and the power is transferred to the inner race and us to the crankshaft what's the NRA start spinning faster than the outer race released causing the interface to spin like every four-stroke gasoline engine motorcycle engines require a source of ignition to ignite the air-fuel mixture for powerstrokes plug is used for this purpose the spark plug wires voltage in excess of 20,000 volts to fire properly in this particular model of the voltage is obtained from the stator of the motorcycle although a 12 volt battery may be used for the same purpose the stator is a stationary coil of wires the flywheel of a motorcycle has a set of permanent magnets which revolves around the stator and produces alternating current in the coils each output from the stator has different purposes as shown here the output for the ignition purpose is received from the Exciter coil coil has a denser winding of thinner wire than the other coils to produce higher voltage for the ignition which is supplied to an electrical known as the capacitive discharge ignition or CDI unit for an AC CDI is shown here the primary function of the CDI unit is to store electric charge and dump the store charge when required a capacitor inside the CDI unit stores the electric charge another component known as a pick-up coil tells the CDI unit when to dump this charge the pickup coil has a small magnet with a coil of wire around it the flywheel has a small Extrusion on its outer surface in approaches and passes the pickup coil a small voltage is developed in the coil does voltage is applied to the CDI unit which closes and electronics which known as a silicon controlled rectifier or scr dump all the charge when the capacitor through the output of the CDI unit to increase the voltage further and ignition coil is used the ignition coil is a Step up Transformer which increases voltage up to 200 times the input voltage which is sufficient to fire the spark plug several other factors contribute to the continuous operation of the engine child are controlled by using a timing chain as shown as long as the engine is running the crankshaft rotates and transfers power to the other components for proper operation single-cylinder engines generally use a counterbalance to reduce the vibration caused by unbalanced forces the clutch helps and smooth transfer of power from the crankshaft to the transmission system the transmission system helps in altering the speed and torque as per our requirement

in motorcycles the torque and RPM of a wheel is controlled by manually shifting gear leavers up or down with our left foot motorcycle gearbox comprises of a series of different gear step which can be switched according to the requirement the gear lever is connected to a shifter shaft and the other end of the shifter shaft is connected to a ratchet mechanism this ratchet mechanism activates as shown in the animation the purpose of this ratchet mechanism is to rotate the shift in drum at specific angles shifting drum has special shaped channels cut into it attachments known as shifting Forks get into these channels gears known as gear dogs or dog clutches fit into the shifting Forks as the shifting drum rotates Fork along with gear dogs sideways as shown in the animation the purpose of sliding dog clutches will be explained shortly let's understand the arrangement of different gears in gearbox there's an input shaft and an output shaft the gears are arranged with their axes aligned to their respective shafts some gears are internally splined these blinds perfectly mesh with external splines of their respective shaft these lines allow gears to slide from side to side while maintaining the same angular speed as the shaft all gears which are shown here in red color are splined some gears are freewheeling gears these gears can freely spin about their Oxys sideways along the shaft years shown in blue color are freewheeling gears the remaining gear is a static air which is attached to the input shaft what's number all these gears from 125 for better visualization please note that all freewheeling gears adjacent to dog clutches have recesses dog teeth can slide into these recesses and lock these two gears with each other now let's see how power is transferred with different gear ratios in a gearbox you can observe here is that every splined gear is meshed with a freewheeling gear if we spin the input shaft power is transferred to the output shaft this is a neutral position of the motorcycle to change into first gear the gear dog number 5 in the output side slides toward the freewheelin gear number one and locks with it since the gear number 5 is splined the output shaft on now spin with this gear is the first gear can we change the second gear the year. Number five in output shaft returns to neutral position phone number for slides to work number to gear and locks with it the technique is similar when we shift to 3rd gear the 4th gear and 5th gear please note here that before Sting from one gear to the other the previously locked gear dog returns to neutral position first only then it slides into another recessed to achieve power transmission this is why there is a neutral in between every geared but in real life we find a neutral position only in between first and second years understand how this happens let's go back to our ratchet mechanism a star shift detent mechanism is responsible for proper shifting of Gears as we can see the star plate has ridges and valleys a spring by a stroller rolls onto these ridges and valleys the position of the roller at each Ridge of the star corresponds to neutral condition as we can visualize the roller cannot rest on The Ridges of the star and immediately disposes to the appropriate Valley preventing the shifting Trump to stop at neutral position this is done in between first and second years so that the roller can briefly rest on this ground off Surface Maybelline the shifter drum to stop at neutral position instead of Shifting directly to second gear the transmission system we showed Here is known as constant mesh transmission system because all gears remain engaged with each corresponding gear mates at all times unconventional sliding mesh transmission gear shifting is done by completely disengaging a gear with one year and re-engaging it with another it involves complex mechanisms and drivers need tremendous skill to operate them in addition in perfect meshing causes gear teeth to grind and where transmission completely eliminate this problem as you might have noticed that some gears are only partially engaged sometimes but this is not a problem because they transmitting power at this moment show me those Gary's which are transmitting power need to be fully engaged at that instant we hope you learned something today you're watching

gearless scooter is one of the most common 2-wheelers popular in many parts of the world they are typically equipped with an automatic transmission system this transmission system is known as continuously variable transmission or CVT the basic principle of a pulley based CVT can be demonstrated by using this simple setup it has a driver pulley and a driven pulley with a variable diameters runs between these two high RPM is obtained by increasing the diameter of the driver pulley and decreasing the diameter of a driven pulley high torque is obtained by doing the opposite Tim allows us to achieve infinite number of draw it was between the minimum and maximum limits it is not possible to Simply change the diameters of solid pulleys as shown in this demonstration so Engineers develop certain mechanisms to obtain similar mechanical characteristics a variator assembly is used for this purpose here the pulley is made up of two continental plates one of them is fixed to the input shaft and the other is free to slide along its axis Riverside also has two conical plates between runs one of these plates is fake stopped while the other can slide sideways a compression spring forces plate to stay close to the other plate this forces the belt to stay at the highest diameter of this pulley in the driver pulley the axial stiffness of the belt pushes the sliding cones farthest apart this causes the driver pulley to have minimum diameter this is the condition of high torque low RPM to obtain high RPM the diameter of the driver pulley decreases and not of the driven pulley increases let's understand how this is achieved in the actual scooter CVT the sliding conical plate of the driver pulley has a set of rollers or sliders is shown here when the engine is at low RPM the rollers are held near the center of the pulley as the engine gains speed centrifical force causes rollers to move outwards along a curved surface these rollers push against the ramp late since the ramp plate is fixed the sliding conical plate is forced towards the other plate let's see the diameter change in slow motion mission of high RPM low as we observed in the demonstration the transmission system includes a centrifugal clutch assembly portion consists of weighted arms held in place by extension Springs these arms are connected to the the clutch housing is connected to the output gear when sufficient speed is reached the centrifical force causes the arms to swing upward and the friction pads engage with the clutch housing the clutch housing transfers power to the rear wheel through a gear train

scooter sem engrenagens é um dos veículos de 2 rodas mais comuns, populares em muitas partes do mundo, eles são normalmente equipados com um sistema de transmissão automática. Este sistema de transmissão é conhecido como transmissão continuamente variável ou CVT. O princípio básico de um CVT baseado em polia pode ser demonstrado por usando esta configuração simples, ela tem uma polia acionadora e uma polia acionada com diâmetros variáveis percorre entre esses dois RPM elevados é obtida aumentando o diâmetro da polia acionadora e diminuindo o diâmetro de uma polia acionada alto torque é obtido fazendo o Tim oposto nos permite atingir um número infinito de tração que estava entre os limites mínimo e máximo, não é possível simplesmente alterar os diâmetros das polias sólidas como mostrado nesta demonstração, então os engenheiros desenvolvem certos mecanismos para obter características mecânicas semelhantes. Um conjunto de variador é usado para isso finalidade aqui a polia é composta por duas placas continentais uma delas é fixada ao eixo de entrada e o outro é livre para deslizar ao longo de seu eixo A margem do rio também tem duas placas cônicas entre as corridas, uma dessas placas é falsa parada enquanto a outra pode deslizar lateralmente uma placa de força de mola de compressão para ficar perto da outra placa isso força a correia a ficar no mais alto diâmetro desta polia na polia motriz a rigidez axial da correia empurra os cones deslizantes mais afastados isso faz com que a polia motriz tenha diâmetro mínimo esta é a condição de alto torque baixo RPM para obter alta RPM, o diâmetro da polia motora diminui e não dos aumentos da polia acionada, vamos entender como isso é conseguido na scooter CVT real a placa cônica deslizante da polia motriz tem um conjunto de rolos ou controles deslizantes é mostrado aqui quando o motor está em baixa rotação os rolos são mantidos perto do centro de a polia, à medida que o motor ganha velocidade, força centrífuga faz com que os rolos se movam para fora ao longo de uma superfície curva, esses rolos empurram contra a rampa tarde, pois a placa da rampa é fixa A placa cônica deslizante é forçada em direção à outra placa, vejamos a mudança de diâmetro na missão de câmera lenta de alta RPM baixa, como observamos na demonstração, o sistema de transmissão inclui uma porção do conjunto de embreagem centrífuga que consiste em braços pesados mantidos no lugar por molas de extensão esses braços estão conectados à carcaça da embreagem está conectada à engrenagem de saída quando a velocidade suficiente é atingida, a força centrífuga faz com que os braços oscilem para cima e as almofadas de fricção engatam na carcaça da embreagem, a carcaça da embreagem transfere força para a roda traseira através de um trem de engrenagens

an engine starter motor is a powerful electric motor used for cranking an engine starter motor has opinion which meshes with a teeth on the flywheel of the engine and turns the crankshaft the model shown here is a pre-engaged type starter motor used in modern vehicles that uses an electric motor to provide torque to the crankshaft this motor can be drawn from the battery if I'd Circuit of power supply shown here the power from the battery is supplied to a solenoid patients which is installed between the battery and the solenoid to turn the power on and off the solenoid is an electromagnet which requires small current to get energized the ignition switch is turned on the solenoid gets energized removing corn known as a plunger slides along the coil which connect to Copper terminals of a contactor switch replace the circuit from the battery to the motor and causes the rotor to spin when the solenoid is D energized the core returns back and disconnect the motor from the battery we may wonder why the solenoid and the contactor used instead of directly connecting the battery to the motor and reducing the complexity the reason behind not using the circuit is the high current demand of the motor Shuffle and demands heavy current for operation to handle this current the ignition switch needs to be unusually large it also requires a very thick wires running from the battery to the switch and then to the motor which is technically inconvenient this is why solenoid is used which demands lower current for being energized another crucial function it helps to slide opinion and engagement with a flywheel before the motor starts to spin the pinion slides towards the flywheel baby rotates on its axis as shown here this rotation is achieved by using a helical spline patient helps meshing opinion with a flywheel more conveniently as opinion and flywheel is properly matched the contactor switch gets closed and the motor spins as we can observe that opinion is considerably small compared to the flywheel the gear ratio the flywheel and pinion is generally from 15 to 1 to 22 1/2 high torque obtained from this gear reduction is still insufficient to crank the engine so a planetary gear set is introduced to increase the torque further planetary gears are incredibly useful for large gear reductions with less weight in limited space The Sun Gear a ring gear carrier and a set of Planeteers and starters the ring gear is fixed where is the input and the planet carrier is the output the setup shown here ratio is 7 to 1 combined gear reduction results and enough torque to spend the as the engine is started the pinion needs to be disengaged from the flywheel to prevent back Drive of the motor which might damage it due to the excessive speed this is done by releasing the ignition switch which D energizes the solenoid and opinion returns back fails to release the ignition switch as soon as the engine is started Google Drive opinion too fast and damage the motor this a one-way clutch has used the one-way clutch has a set of rollers installed between the outer and inner races when the Elder race is rotated by the motor Bowlers get trapped and transfer power to the pinion engine is started and drives opinion of high-speed the rollers get released and power transfer is stopped

um motor de arranque é um motor elétrico potente usado para dar partida em um motor de arranque. Tem opinião que engrena com um dente no volante do motor e gira o virabrequim. O modelo mostrado aqui é um motor de arranque do tipo pré-engatado usado em veículos modernos que usa um motor elétrico para fornecer torque ao virabrequim este motor pode ser retirado da bateria se eu Circuito da fonte de alimentação mostrado aqui a energia da bateria é fornecida a um paciente solenóide que é instalado entre a bateria e o solenóide para girar a energia ligada e desligada do solenóide é um eletroímã que requer uma pequena corrente para ser energizado, a chave de ignição é ligada e o solenóide fica energizado removendo o milho conhecido como um êmbolo desliza ao longo da bobina que se conecta aos terminais de cobre de uma chave contator substituindo o circuito de a bateria para o motor e faz com que o rotor gire quando o solenóide é energizado, o núcleo retorna e desconecta o motor da bateria, podemos ganhar der por que o solenóide e o contator usados em vez de conectar diretamente a bateria ao motor e reduzir a complexidade, o motivo por trás do não uso do circuito é a alta demanda de corrente do motor Shuffle e exige corrente pesada para operação para lidar com essa corrente a chave de ignição precisa ser anormalmente grande, também requer fios muito grossos que vão da bateria ao interruptor e, em seguida, ao motor, o que é tecnicamente inconveniente. É por isso que o solenóide é usado, o que exige corrente mais baixa para ser energizado, outra função crucial que ajuda a deslizar a opinião e engate com um volante antes que o motor comece a girar o pinhão desliza em direção ao volante bebê gira em seu eixo, como mostrado aqui, esta rotação é conseguida usando um paciente de spline helicoidal ajuda a encaixar a opinião com um volante de forma mais conveniente, visto que a opinião e o volante são devidamente combinados a chave do contator é fechada e o motor gira, pois podemos observar que a opinião é consideravelmente pequena, compare d para o volante, a relação de engrenagem do volante e do pinhão é geralmente de 15 a 1 a 22 1/2, o alto torque obtido a partir desta redução de engrenagem ainda é insuficiente para dar partida no motor, então um conjunto de engrenagens planetárias é introduzido para aumentar o torque de outras engrenagens planetárias são incrivelmente úteis para grandes reduções de engrenagem com menos peso em espaço limitado. The Sun Gear um suporte da coroa dentada e um conjunto de planetárias e acionadores a coroa é fixada onde está a entrada e o suporte planetário é a saída. A relação de configuração mostrada aqui é 7 para 1 resultados combinados de redução de marcha e torque suficiente para gastar conforme o motor é ligado, o pinhão precisa ser desengatado do volante para evitar a tração traseira do motor que pode danificá-lo devido à velocidade excessiva. que D energiza o solenóide e a opinião retorna, falha em liberar a chave de ignição assim que o motor é ligado. ch usou a embreagem unidirecional tem um conjunto de roletes instalados entre as pistas externa e interna quando a corrida Elder é girada pelo motor. Os jogadores ficam presos e transferem a potência para o motor de pinhão é iniciado e impulsiona a opinião sobre os roletes de alta velocidade seja liberado e a transferência de energia seja interrompida
