Drive shafts
1 - connecting shaft of the right drive shaft, 2 - right drive shaft, 3 - external hinges, 4 - internal hinges, 5 - left drive shaft, 6 - hub nuts, 7 - nut protection element from loosening, 8 - cotter pin, 9 - external cover, 10 - inner cover
Torque from the engine to the front wheels is transmitted through two steel drive shafts of different lengths.
The outer ends of the drive shafts are inserted into the wheel hub and secured with nuts. The inner ends of the drive shafts are installed and secured in the differential.
Hinges of equal angular velocities (SHRUS) installed on both sides of the drive shafts and provide smooth and efficient transmission of torque during suspension operation and when turning the front wheels. The outer CV joint consists of a body, separator, inner race and balls. Grooves are made in the hinge body and cage to accommodate balls. The grooves of the longitudinal plane are made along the radius, which provides a large angle of rotation of the outer hinge. The inner hinge differs from the outer one in that instead of balls, rollers are used, mounted on a drive shaft.
On the right side, due to the large length of the drive shaft, the internal hinge is located approximately in the middle of the shaft length, and the intermediate support bearing is fixed in the suspension of the power unit installation.
