clutch means can according to the driver’s requirements, the separation member driving shaft and the driven shaft or engaged in work, car, automobile transmission can be used to manipulate the start, transmission, reversing or stopping the like. .
1 acting clutch assembly
of the clutch mainly in the following three aspects: First, to ensure a smooth start car; Second, to prevent overloading the driveline; Third, to achieve a smooth shift ;.
2 works
The active portion of the clutch and the driven part by friction between the contact surfaces, or by a magnetic drive (electromagnetic clutch) to transmit torque with a liquid as the driving medium (hydrodynamic coupling), or the two temporary separation between the can, but also is gradually engaged, in turn, allows the drive during mutual rotation of the two parts.
3. The clutch assembly structure
the torsion damper
When the clutch is engaged, the engine torque emitted by the flywheel and the pressure plate to pass a friction lining on both sides of the movable disc, the disc drive body and the driven damper plate and the driven plate riveted together rotatable body. The damper body and the movable disc plate and the damper springs by six torque passed the driven hub. Because the role of elastic bodies, so that rotation of the drive train by the impact of this can be alleviated. Torsional vibrations in the drive train causes the driven hub body relative to the movable plate and the damper plate is rotated back and forth, interposed between them * frictional damper torsional vibration energy consumption, the torsional vibration damping down.
The clutch section
driven portion is a single piece, two-piece or multi-piece composed of the driven plate, the active part of it by friction coming the power transmitted to the input shaft of the transmission. Driven by the driven disc plate body, the friction plate and the driven hub of three basic parts. To avoid resonance rotational direction, easing the drive train from the impact load, on most cars are equipped with a clutch driven plate is attached torsion damper.
In order to smoothly start the automobile, the clutch engagement should be gentle, which requires the driven plate having a certain elasticity in the axial direction. For this reason, often in the peripheral portion of the movable plate body, radial and circumferential slots. And then dividing the sector portions in the circumferential direction is formed into the undulating warp, on both sides of the two friction plates are raised portion corresponding thereto riveted, so that when the driven plate is compressed, the pressing force with warped quadrants flattened and gradually increased so as to achieve the effect of a soft engagement.
