Folksvagen Sharan/Sharan repair>> Coupling>> Drive of deenergizing of coupling



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

The prevention
The brake liquid is strongly poisonous, it is easy воспламенима, гигроскопична (absorbs a moisture from air) and destroys paint and varnish coverings. To neutralise its influence it is possible a considerable quantity of cold water.

This tank is divided on two parts: one for brake system, and another for a drive of deenergizing of coupling. These systems work independently from each other.
The drive of deenergizing of coupling hydraulic, consists of a pedal, the main cylinder, the pipeline, a hose and the working cylinder. Coupling deenergizing is carried out by the working cylinder which influences directly on выжимной the bearing, unlike other models of cars of companies "Volkswagen" and «Ford» where the working cylinder actuates выжимной the bearing through the lever (plug).
Fig. 231. Position of the working cylinder and выжимного the bearing on an inside картера couplings





The working cylinder with выжимным the coupling bearing are inside картера couplings (fig. 231) on primary to a transmission shaft. The goffered dustproof cover protects the working cylinder and выжимной the bearing from a dirt.
Fig. 232. Parts of a hydrodrive 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 Н·м; 8 — the main cylinder; 9 — a lock collar; 10 — a lining, always on replacement; 11 — an O-shaped sealing ring; 12 — a hose / the pipeline; 13 — an arm; 14 — a bolt, 25 Н·м; 15 — an arm on a transmission; 16 — a nut, 20 Н·м; 17 — a bolt, 20 Н·м; 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 выжимным the bearing; 24 — a bolt with a fillet, 11 Н·м; 25 — the goffered cover; 26 — a dustproof cap; 27 — a bolt for air removal; 28 — накидная a nut, 20 Н·м; 29 — the pipeline





The main cylinder 8 (fig. 232) couplings with a tank 1 for a brake liquid is located near to an axis of a pedal of 4 couplings, on the left side, and connected to a pedal a rod 6 pushers. By pressing a pedal of coupling 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.
