The main purpose of the transmission or gearbox is to provide a selection of gear ratios between the engine and driving wheels, so that the vehicle can operate satisfactorily under all driving conditions. Gear selection may be done manually by the driver or automatically by a hydraulic control system.
The function of the propeller(drive) shaft is to transmit the drive from the gearbox to the input shaft of the rear axle and differential assembly. Flexible joints allow the rear axle and wheels to moveup and down without affecting operation.
The rear axle and differential unit transmits the engine'' s rotational power through 90 from propeller shaft to axle shaft to road wheels. A further function is to allow each driving wheel to turn at adifferent speed; essential when cornering because the outer wheel must turn further than the insidewheel. A third function is to introduce another gear ratio for torque multiplication. In a rearwheel drive vehicle, the axles can be solid or contain joints to allow for movement of suspension. For afrontwheel drive vehicle, the drive shaft has universal joints to''allow for suspension and steering movement.
