Drive shafts
Drive shafts transmit torque from the engine, transmission and differential to the front wheels. In the gearbox drive shaft spline connection attached to the differential side gears. Fixation of the spline tip of the internal hinge of a power shaft side gear made snap ring. When installing the lock ring is compressed into the groove of the shaft. Once the shaft is fully seated in the side gear differential lock ring expands and fixes slotted tip from axial movement.
External hinges are attached to the drive shafts of front wheel hub mounted on bearings. Fixing the shaft to the hub nut is carried out with a shoulder. To eliminate loosening nuts collar nut bent into the recess of the drive shaft. The play between the hub and the drive shaft spline arrangement is eliminated. The slots are located right in the hub, and the splines on the shaft are made at a slight angle. Different versions of splines provides a connection with preload, that is interference fit, eliminating all regulations.
Constant velocity joints (CV joints) installed on both sides of the drive shaft. All outer CV joints - such Birfield, and internal - tripoidnogo type. Tripoidnogo type CV joints are used to prevent the transmission of vibrations through the engine drive shaft on a car body.
CV joints are needed to transmit torque and motion compensation front suspension. Also, CV joints allow you to change the length of the drive shaft and the torque transmitted by the ever-changing angles.
The use of universal constant velocity joints is determined by the need to compensate for motion front suspension during the transmission of torque through the drive shaft. As the movement of suspension CV joints allow you to change the length of the drive shafts transmit torque under the constantly changing angles. In order to ensure the required degree of freedom, constant velocity joints used in the housing bearings. In compounds with tripoidnogo type used three rolls mounted on bearings and needle roller tripoidnogo connection. In compounds of both types of machined outer ring under the housing SHRUS.
Tripoidnye joints can be disassembled and repaired. Protective covers, outer CV joints Birfield be repaired only in gathering with shaft.
