Repair Sharan/Sharan Volkswagen>> Coupling>> Drive of switching off of coupling

For a drive of switching off of coupling brake liquid which is in the same tank, as liquid of a drive of brakes is used.

Brake liquid is strongly poisonous, it is easy воспламенима, is hygroscopic (absorbs moisture from air) and destroys paint and varnish coverings. To neutralize its influence it is possible a large amount of cold water.

This tank is divided into two parts: one for brake system, and another for a drive of switching off of coupling. These systems work independently from each other.
The drive of switching off of coupling hydraulic, consists of a pedal, the main cylinder, the pipeline, a hose and the working cylinder. Switching off of coupling is carried out by the working cylinder which the bearing influences directly on vyzhimny, unlike other models of cars of the Volkswagen and Ford companies where the working cylinder actuates vyzhimny the bearing via the lever (fork).

Fig. 231. Position of the working cylinder and the vyzhimny bearing on inside of a case of coupling

The working cylinder with the vyzhimny bearing of coupling are in a coupling case (fig. 231) on primary to a transmission shaft. The goffered dustproof cover protects the working cylinder and vyzhimny the bearing from dirt.

Fig. 232. Parts of a hydraulic actuator of coupling: 1 — a tank; 2 — a feeding hose; 3 — the pedal block; 4 — a coupling pedal; 5 — the safety holder; 6 — a pusher rod; 7 — a bolt, 20 N · m; 8 — the main cylinder; 9 — a lock collar; 10 — laying, always on replacement; 11 — an O-shaped sealing ring; 12 — the hose/pipeline; 13 — an arm; 14 — a bolt, 25 N · m; 15 — an arm on a transmission; 16 — a nut, 20 N · m; 17 — a bolt, 20 N · m; 18 — a lock collar; 19 — a dustproof cap; 20 — a transmission; 21 — an epiploon; 22 — an O-shaped sealing ring, always on replacement; 23 — the working cylinder with the vyzhimny bearing; 24 — a bolt with a fillet, 11 N · m; 25 — the goffered cover; 26 — a dustproof cap; 27 — a bolt for air removal; 28 — a cap nut, 20 N · m; 29 — the pipeline

The main cylinder 8 (fig. 232) of coupling with a tank 1 for brake liquid is located near an axis of a pedal of 4 couplings, on the left side, and is connected to a pedal a rod of the 6th pusher. By pressing a coupling pedal the pusher moves the piston connected to it into the main cylinder. Thanks to it in the main cylinder pressure which through a hose is transferred to the working cylinder of 23 couplings is created.
