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
