The vehicle is equipped with a single-plate, dry, permanently closed clutch with a central pressure spring and a torsional vibration damper on the driven disk.
The leading part of the clutch is a non-separable unit, includes a casing 18 (see fig. Clutch assembly) clutch, pressure plate 4 and diaphragm pressure spring 2. The clutch housing is secured to flywheel 6 with mounting pins and bolts 8. Pressure plate 4 is connected to housing 18 by three pairs of steel plates, each of which is riveted at one end to the housing and at the other to the pressure plate. Through clamps, the pressure plate is connected to the outer edge of diaphragm spring 2, which rests on two rings 17 of circular cross-section, fixedly secured to the housing by stepped rivets 3.
Driven disk 5 is steel and has slots that divide it into twelve sectors bent in different directions. Friction linings are riveted to the disk sectors independently of each other. To dampen torsional vibrations, the driven disk is connected to the hub using a torsional vibration damper (damper).
The clutch release drive is hydraulic. It consists of the master cylinder 1 (see Fig. Clutch pedal and master cylinder), clutch release cylinder 10 (see fig. Slave cylinder and clutch release fork), forks 3 and bearing 1 for disengaging the clutch, reserve tank and clutch pedal with servo spring. The tank and drive cylinders are connected to each other by pipelines.
