At the included coupling, i.e. When the coupling pedal is in the top position, тарельчатая the spring of a leading part of coupling moves press a disk of coupling towards the engine. Thus the disk of coupling supplied with frictional overlays, is clamped between a press disk and a flywheel, and the twisting moment is transferred from the engine to a transmission. By pressing of a pedal of coupling the persistent bearing of coupling moves press a disk back. The coupling disk then the shaft of the engine and a transmission shaft can rotate independently from each other is thus released.
On all models dry one-disk coupling which consists of a disk of coupling, a press disk, тарельчатой springs, a casing and the press bearing is established.
The coupling disk freely moves on шлицах a primary shaft of a transmission and is clamped between a flywheel and a press disk effort which is created тарельчатая by a spring. From two parties of a disk of coupling приклепаны frictional overlays. The leading part of a disk of coupling incorporates to a nave through details гасителя крутильных fluctuations which provides elastic communication between them. Necessity гасителя крутильных fluctuations is caused by the following.
At sharp change of speed of movement of the car, arrival on roughness of road, sharp inclusion of coupling, and also owing to non-uniform work of the engine in car transmission there are the dynamic loadings causing a twisting (раскручивание) of shaft of transmission. Non-uniformity of a twisting moment of the engine can cause considerable overloads in transmission owing to occurrence крутильных fluctuations and a resonance at coincidence of the frequencies, transferred loadings to frequencies of own fluctuations of transmission. Elastic fluctuations of transmission result not only in noise occurrence in mechanisms and units, but also to dangerous vibrations, and sometimes and to breakages of details when the amplitude of fluctuations reaches the big size. Energy крутильных fluctuations absorbs гаситель.
The vyzhimnoj bearing is established from the forward party of a transmission on the directing plug. Bearing moving is made by the lever of deenergizing of coupling. Pressing of a pedal of coupling moves the piston in the main cylinder and compresses a liquid which on a hose is transferred to the working cylinder of coupling. Under pressure the piston of the working cylinder of coupling moves ся and puts in action the lever of deenergizing of coupling. The lever of deenergizing of coupling moves выжимной the bearing which influences a spring of a press disk and takes away press a disk from a coupling disk. Coupling adjustment occurs automatically.
Depending on a design of the flywheel established on the engine, use ся various disks of coupling. If the flywheel consisting of two sections with a spring and демпфирующей by system the disk of coupling without springs гасителя fluctuations is established is established. If on the engine the flywheel consisting of one detail the disk of coupling with springs гасителя fluctuations (a classical disk of coupling) is established is established.
