Coupling actuating

Force from which we press a coupling pedal, should be transferred to the vyzhimny bearing. In Audi A4 it is carried out by a hydraulic way – as well as in brake system. When you press a coupling pedal, the piston in the working cylinder (on a coupling pedal) forces out certain amount of liquid and передавливает it to the main cylinder (on a transmission). There the piston leaves the cylinder a little and thus the lever of switching off actuates vyzhimny the bearing.

 Council: Each connection of coupling causes sliding of overlays of a conducted disk of rather opposite surfaces of a friction and their heating. Especially strong wear is promoted by start from a place on high turns which is called as cavalry, start on the 2nd transfer, movement at intersections on the 2nd or 3rd transfer with partially wrung out pedal of coupling or movement uphill.

Type of the coupling established on (dismantled) four-cylinder engine

1–a conducted disk of coupling;
2–a gear wreath of a flywheel (the starter is linked to a gear wreath);

3–press coupling disk.
