The connection of the two parts of the cardan shaft is carried out by a splined sliding coupling type. This connection allows the rear of the propeller shaft to move along the axis, resulting in a change in the overall length of the propeller shaft. The cardan shaft is connected to the flanges of the gearbox and the rear final drive through rubber flexible couplings. A vibration damper is installed between the front rubber clutch and the cardan shaft. The propeller shaft center bearing housing is bolted to the bottom of the vehicle. A universal joint is installed in the rear section of the driveshaft behind the center bearing, which allows torque to be transmitted at an angle.
The composition of the main reverse gear includes: drive gear, gear wheel, differential and output flanges. A flange is installed on the pinion shaft, which is connected to the cardan shaft through an elastic rubber coupling. The gear wheel is bolted to the differential box and transmits torque through side gears and flanges to the drive shafts. The differential ensures the rotation of the drive wheels on different sides of the car at different speeds. This is necessary for cornering where the wheel on the inside of the corner rotates in a much smaller radius than the wheel on the outside of the corner. In other words, the wheel on the inside of the turn travels a shorter distance in a certain amount of time than the wheel on the outside of the turn, so its rotation speed must also be slower. However, in practice, the wheels rarely turn at exactly the same speed, even when driving on a straight road, because even a small difference in wheel diameters or passing the wheels on the same side on uneven ground causes a speed difference that requires a differential to compensate.
The drive shafts transmit torque from the output flanges of the rear final drive to the rear wheels. Equal velocity joints are installed on both sides of each drive shaft. The inner CV joints are bolted to the output flanges of the rear final drive, and the outer CV joints are installed in the grooves of the wheel hub and fastened with a nut.
To repair the rear final drive requires the use of a number of special tools, so this work must be carried out at a service station.
