Coupling - the general description and check of serviceability of functioning

On all cars equipped РКПП, one-disk coupling of dry type with диафрагменной a spring is established. The disk couplings (conducted) is equipped шлицованной by a nave providing its free sliding lengthways шлицов of a primary shaft of a transmission. Conducted and press disks are kept pressed to each other at the expense of the effort developed диафрагменной by a spring of a press disk.

Conducted disk and coupling basket (with a press disk).

The system of deenergizing of coupling functions at the expense of hydraulic pressure. The hydraulic system of deenergizing of coupling consists of a pedal of coupling, the main cylinder with the tank of a hydraulic liquid, hydraulic lines, the executive cylinder and the lever of deenergizing of coupling which is in the coupling case.

At squeezing of a pedal of coupling hydraulic pressure is put to выжимному to the bearing through the lever of deenergizing of coupling. The bearing nestles on petals диафрагменной springs of a press disk in assemblage of a basket which, in turn, releases a conducted disk.

At discussion of the procedures connected with service of knots of coupling there can be the problems connected with terminology as common names of many components differ from accepted by manufacturers. For example, the conducted disk can be called also as a disk of coupling or simply disk, выжимной the bearing sometimes name through or the bearing of deenergizing of coupling, the cylinder of deenergizing of coupling is more often mentioned as executive or working.

Except change of obviously damaged components it is necessary to make regularly preventive checks of a condition of coupling for the purpose of diagnostics of its malfunctions.


    The first always makes check of level of a liquid in the main cylinder of coupling. If level is insufficient, it is necessary to make having added and carefully to investigate all hydraulic system on presence of traces of leaks. If the tank of the main cylinder appears is empty, the system should be pumped over with the subsequent check of functioning of coupling. For quality check of deenergizing of coupling start the engine and leave its working on turns of normal idling at established on neutral transfer РКПП (coupling is included - the pedal is released). Switch off coupling (squeeze out a pedal), wait for some seconds and translate a box in reverse gear position. Thus there should be no gnash and other extraneous noise. Presence of those with the big share of probability specifies in malfunction of a press or conducted disk of coupling (provided that РКПП is perfectly in order). For check of completeness of deenergizing of coupling start the engine (a lay brake cock for the purpose of prevention страгивания the car) and keep a coupling pedal approximately in 13 mm over a floor. Some times switch a box, translating it from position of the first transfer to position back and back. If smoothness in box switchings is absent, malfunction of components of coupling takes place. Check up a course of a pusher of the executive cylinder. At completely squeezed out pedal the pusher of the executive cylinder should act considerably. If it not so, check up liquid level in the main cylinder. Make visual check of a condition of the axial plug in the top part of a pedal of coupling. Make sure of absence of its signs закусывания or excessive люфта.
