On all cars with a mechanical transmission dry, disk coupling with the central spring of diaphragm type is established. The conducted disk of coupling has the plug with vents on an internal surface that allows it to slide along shlits of an entrance shaft of a transmission. Conducted and press disks of coupling are kept together by pressure of plates of the diaphragm spring established in a press disk of coupling.
On cars the hydraulic drive of switching off of coupling is used. It consists of a pedal of coupling, the main cylinder and a tank with hydraulic liquid, hydraulic tubes, the working cylinder which sets in motion a fork of switching off of coupling and vyzhimny the bearing.
By pressing a coupling pedal for coupling switching off, hydraulic pressure is transferred to the external end of a fork of switching off of coupling. At turn the fork puts pressure on vyzhimny the bearing. That, in turn, puts pressure upon plates of a diaphragm spring that releases coupling.
At the description of elements of coupling the used terminology can cause problems as in certain cases the old names used by the producer changed. For example, the conducted disk often is called as the conducted disk of coupling or simply as a disk of coupling, press the disk sometimes is called as a coupling casing, the coupling switching off bearing sometimes is called as the vyzhimny bearing, and the coupling switching off cylinder sometimes is called as the working cylinder.
Besides replacement of elements of coupling which have obvious damages, it is necessary to carry out diagnostics of the reasons of emergence of malfunction.
