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