The clutch is mounted on the flywheel and is covered by an aluminum crankcase that is bolted to the cylinder block with four bolts. On the other hand, the crankcase is connected to the gearbox.
On the splines of the input shaft of the gearbox, a hub is freely installed, on which driven disk, divided by radial slits into twelve sectors. Friction linings made of a special material are riveted to the driven disk on both sides. The torque from the driven disk to its hub is transmitted through a spring-friction damper (vibration damper).
Basket (leading part of the clutch) attached to the flywheel with six bolts and includes a pressure plate, a casing and a diaphragm pressure spring. The pressure plate is movably fixed on the casing. Under the action of a diaphragm spring, the driven disc is clamped between the pressure plate and the flywheel.
The clutch is released hydraulic drive with suspension pedal. Pedal The clutch is mounted on a common axis with the brake pedal, fixed on the bracket of the partition of the engine compartment. Attached to the top of the pedal is a spring that reduces the clutch release force. A pusher is pivotally attached to the pedal. The pusher with a hemispherical end enters the seat of the piston of the master cylinder of the clutch release drive. On the one hand, the pedal travel is limited by the adjusting screw, and on the other hand, by the piston stroke in the cylinder.
master cylinder located in the engine compartment and fastened with two nuts to the pedal assembly studs. The cylinder is connected by a hose to the hydraulic clutch release reservoir. Tank mounted on the bulkhead of the engine compartment on the left side. The tank is made of translucent plastic, which makes it easy to check the fluid level in the drive. A corrugated rubber liquid damper is installed in the reservoir lid. To connect the cavity of the tank with the atmosphere, a hole is made in the lid.
A pipeline fitting is connected to the main cylinder, supplying fluid from the main cylinder to the working one, the other end of this pipeline is connected to the tip of the hydraulic drive hose. The tip of the hose is fixed with a bracket in the body bracket. The other end of the hose is connected to the hydraulic clutch release cylinder.
Worker cylinder Attached to the clutch housing with two bolts. The cylinder rod is a pusher clutch release forks, mounted on a ball joint in the clutch housing. With one end, the fork rests on the adjusting nut of the pusher, and with the other end it is pressed against release bearing clutch. The bearing clutch is put on the guide sleeve of the front cover of the gearbox and has the ability to move longitudinally.
When the engine is running, the driving and driven parts of the clutch rotate as one unit, transferring torque from the engine crankshaft to the gearbox input shaft. When the clutch pedal is pressed, the force is transmitted through the hydraulic drive from the working cylinder to the clutch release fork, which, turning on a ball bearing, moves the release bearing along the guide sleeve. The bearing acts on the diaphragm spring of the basket, it bends on the support rings and takes the pressure plate away from the driven disk. In this case, the input shaft of the gearbox is disconnected from the crankshaft of the engine, the transmission of torque is stopped. When the pedal is released, all parts of the clutch return to their original position under the action of the springs.
