Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Coupling>> General information
Coupling (fig. 7.1) is intended for short-term separation of the engine and transmission at gear shifting or braking and their smooth connection at a car troganiye from a place, and also protection of details of transmission from dynamic loadings.
The coupling applied on cars, one-disk, dry, constantly closed type, with the central press spring of diafragmenny type and a quencher of krutilny fluctuations on a conducted disk.
The principle of action of coupling is based on torque transfer from a flywheel on a conducted disk of coupling, so, and on primary shaft of a transmission, at the expense of the forces of the friction arising between disks at included coupling. Press the disk clamps among themselves and a flywheel a conducted disk with the effort which is not allowing its pro-slippings. For switching off of coupling vyzhimny the bearing influences a spring of a press disk of coupling and wrings out press a disk from a flywheel therefore the conducted disk is released and torque transfer between the engine and a transmission stops.
Press the disk of coupling fastens bolts to a flywheel. The conducted disk of coupling is located between a press disk and a surface of a friction of a flywheel. The nave of a conducted disk of coupling is established on primary to a shaft of a transmission and freely moves on shaft grooves.
Because at each inclusion and switching off of coupling there is an insignificant wear of overlays of a conducted disk of coupling, periodic adjustment of a free wheeling is necessary for preservation of normal working capacity on coupling with a hummock drive. Coupling with a hydraulic drive of adjustment does not demand, as by each pressing a coupling pedal wear is automatically compensated by necessary amount of the liquid arriving from a tank of a hydraulic drive of brake system, the general with a hydraulic drive of coupling.
