The car has a single-disk, dry, permanently closed clutch, with a central pressure diaphragm 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 cover is attached to the flywheel 6 with dowel pins and bolts 8. The pressure plate 4 is connected to the casing 18 by three pairs of steel plates, each of which is riveted to the casing at one end and to the pressure plate at the other. Through the clamps, the pressure plate is connected to the outer edge of the diaphragm spring 2, which rests on two rings 17 of circular cross section, fixed on the casing with stepped rivets 3.
Driven disk 5 is steel, has radial slots that divide it into twelve sectors, bent in different directions. Friction linings are riveted to the sectors of the disk, independently of each other. To dampen torsional vibrations, the driven disk is connected to the hub using a torsional vibration damper (damper).
Clutch release drive hydraulic. It consists of a master cylinder 2 (see fig. Clutch pedal and master cylinder), clutch release cylinder 10 (see fig. Slave cylinder and clutch release fork), fork 3 and clutch release bearing 1, reserve reservoir and clutch pedal with servo spring. The reservoir and drive cylinders are interconnected by pipelines.
From June 1972 to November 1978, the described cars were equipped with a clutch and brake pedal bracket, produced specifically for these models. Since December 1978, a bracket has been installed, unified at the attachment point, for cars with and without a vacuum booster. On unified brackets, a clutch pedal from a VAZ 2103 car is installed.
