On all models equipped РКПП, one-disk coupling of dry type with диафрагменной a spring is used. The nave of a frictional (conducted) disk is equipped longitudinal шлицами, entering into gearing with шлицами pins of a primary shaft of transmission. Frictional and press coupling disks are kept in contact with each other at the expense of the effort developed диафрагменной by a spring of a press disk. The design of coupling and its drive is presented on an accompanying illustration.

Design of coupling and components of its drive

1— The Conducted (frictional) disk of coupling
2 — Assemblage of a basket of coupling with a press disk
3 — the Plug of deenergizing of coupling
4 — the Bearing of deenergizing of coupling

5 — the Lever of deenergizing of coupling
6 — a coupling Drive
7 — РКПП
8 — the Cover of a basket of coupling
9 — a coupling Pedal

By pressing a pedal of coupling the bearing of deenergizing of coupling nestles to диафрагменной to a spring of a press disk, being under pressure through a cable of a drive of coupling and the lever. Thus press the coupling disk unloads and the conducted disk does not nestle any more on a flywheel. Contact of the engine with РКПП stops.

If the coupling pedal is released, press the disk presses a conducted disk to a flywheel and twisting moment transfer is again restored, since the pressed disk through шлицевое connection contacts primary shaft РКПП.

At each inclusion and deenergizing of coupling owing to easy sliding there is a deterioration of frictional overlays of a conducted disk. Service life of a conducted disk, nevertheless, makes at least 100 000 km of run of the car. Deterioration basically depends on loading on the power unit (for example, trailer towage) and style of driving. Within the limits of maintenance service carrying out adjustment of a pedal of coupling is required only. In the course of deterioration of frictional overlays the coupling pedal is displaced upwards.


At coupling service, besides replacement of the components having obvious damages, it is necessary to make some primary checks (it is supposed that the transmission is in good repair):
  1. For an estimation of time of switching of coupling start the engine on normal turns of idling. Make sure that neutral transfer is included and release a coupling pedal. Now squeeze out a pedal of coupling and, having waited for some seconds, include a reverse gear. Switching should not lead to occurrence of a gnash and other extraneous noise, with high degree of probability specifying in malfunction of a conducted disk or assemblage of a basket of coupling;
  2. For check of completeness of deenergizing of coupling cock a lay brake and start the engine. Keeping a coupling pedal at height about 13 mm over a floor, попереключайте a transmission between the first and back transfers. Presence of hindrances at lever switching speaks about malfunction of components of the mechanism of deenergizing;
  3. Make visual check of a condition of axial plugs in the top part of a pedal of coupling. Make sure of absence of signs of jamming and excessive люфта axes.
