The transmission of the vehicle transfers the force of the engine to the wheels at different speeds and loads. It has discs or cones of bronze or another material to brake and synchronize the gears to avoid the wear when making the changes of speeds. It also receives all the knocks of the wheels, vibrations of the cardan and the engine and friction of friction between the gears.
The rear differential consists of a gear set that changes the rotation of the cardan shaft at a right angle to a movement of a perpendicular axle. It reduces the speed of rotation to increase the torque and the differential gear to transfer the power to the rims smoothly when there are differences in rotation, between the inner rim and the outer rim, when crossing a curve.
