The differential ensures that the right and left drive wheels roll at different speeds when the vehicle turns and when driving on uneven roads. The differential transmits torque from the cardan shaft of the gearbox via a bevel gear to the two rear wheel drive shafts.
Rectilinear motion
Both rear wheels have the same speed as the differential gear. The bevel gears of the differential rotate evenly.
Driving in corners
The wheel that passes the outer radius travels a greater distance than the inner one. The different speeds of the wheels are equalized, otherwise one of them would constantly slip in the turns.
This is achieved by a bevel gear: the faster rotation of the outer bevel gear is transmitted through the intermediate gears to the outer gear, and it rotates more slowly.
