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.
