Coupling

In the car with the mechanical transmission coupling performs two functions: first, at its switching off communication between the engine and the transmission as transfer switches only in the absence of loading has to be interrupted. Secondly, coupling at the beginning of operation of the engine softly "connects" all knots of the drive which are still in rest, with each other.
