Coupling In the car with a mechanical transmission coupling carries out two problems: on the one hand, with its help it is possible to divide at switching connection the engine/transmission because only not loaded transmission supposes switching. On the other hand, at dispersal of the working engine coupling can softly "connect" to for the present staying idle parts of a drive. Transfer of the moment from the engine to transmission occurs by means of coupling. It works exclusively at the expense of a friction, and it can be imagined as follows: two contact surfaces densely nestle on the third and hold it so strong that it is compelled to rotate together with these two. The sense of a design consists that this connection can be at any moment disconnected, differently both these details with the same success it would be possible to screw one on another. We name them by name: to the engine are rigidly connected a flywheel and loaded with effort of a spring press a disk. Between them the conducted disk rigidly hooked by teeths with shaft of a transmission is clamped.The following important function carries out выжимной the bearing: by pressing of a pedal of coupling it nestles by means of a drive of management of coupling (the following section) to a press disk see and overcomes force of a spring of a press disk. The conducted disk thereby is released from the "clamped" position and can freely rotate between a press disk and a flywheel. Twisting moment transfer between the engine and a transmission is stopped. If the coupling pedal is again released, тарельчатая the spring of a press disk again presses a conducted disk to a flywheel, at one stroke stopping its free rotation. All three elements again represent rigidly connected connection. The engine twisting moment can be transferred a drive. |
