17 — a protective cover; 18 — a pusher; 19 — the piston; 20 — a cuff; 21 — a spring; 22 — the case of the working cylinder of the drive of coupling; 23 — the union for removal of air (pumping); 24 — a bracket of fastening of the bearing of switching off of coupling; 25 — the coupling switching off bearing; 26 — a pin; 27 — a coupling switching off fork; 28 — the conducted disk; 29 — a casing assembled; 30 — the coupling switching off lever


On the car one-disk dry coupling with the central diaphragm press spring is applied. Cars with petrol engines are completed with coupling with the mechanical (hummock) drive, cars with the diesel engine — coupling with the hydraulic drive. The conducted disk has the built-in quencher of tortional fluctuations (damper). Coupling switching off bearing ball, self-centering. Details of coupling are represented in fig. 4.1 and 4.2. Characteristics of couplings are provided in tab. 4.1.
