12.2. Coupling - general information
Coupling is located between the engine and a transmission, consists of a conducted (frictional) disk, a casing of coupling with a press disk and a hydraulic actuator of switching off of coupling. The structure of a drive includes the main thing the worker cylinders, a pedal, a fork of switching off of coupling and vyzhimny the bearing. The frictional disk consists of two ring frictional slips clamped by a diafragmenny spring between a flywheel and the press disk Rotation from the engine on primary shaft of a check point is transferred through a frictional disk and a nave.
The pedal of coupling is connected to the main cylinder which together with a tank of a hydraulic actuator are mounted on a partition of a motor compartment from the driver. By pressing a pedal, effort moves forward liquid of hydraulic system to the working cylinder. The piston in the working cylinder actuates a fork of switching off of coupling which moves vyzhimny the bearing Vyzhimna the bearing rests against a heel therefore action of a diafragmenny spring weakens and coupling is switched off (primary shaft is disconnected from the engine).
In process of wear of a frictional disk the gap between a frictional and press disk gets out automatically.
Access to details of coupling is complicated, therefore at each removal of the engine or transmission attentively examine disks of coupling and vyzhimny the bearing. If necessary replace these details. The frictional disk is replaced without fail, irrespective of its condition.
