Description

Technical Field

[0001] The utility model belongs to the technical field of clutches and relates to a clutch separation operating mechanism. Background Art

[0002] The clutch release system structure is mainly composed of the operating mechanism and the related parts of the clamping mechanism. The operating mechanism is the device that the driver controls the clutch release or engagement through the clutch pedal. It mainly consists of the following parts:

[0003] Separation rocker arm: connected between the separation pump and the separation fork shaft, used to transmit the separation force generated by the separation pump.

[0004] Release fork shaft: connected between the release rocker arm and the release fork, used to transmit the release force.

[0005] Release fork: connected to the release lever, pushes the release bearing forward through the force generated when the driver presses the clutch pedal.

[0006] Release bearing: installed on the release fork, in contact with the release finger on the pressure plate or the release finger of the diaphragm spring. When the release fork is pushed, the release bearing will press the clamping mechanism of the pressure plate, causing the pressure plate to move backward, thereby achieving clutch release.

[0007] Release rocker arm, release fork, etc.: These components play the role of connecting and transmitting force in the operating mechanism to ensure that the clutch can be separated and engaged smoothly.

[0008] See also Figure 1 and Figure 2 The traditional separation system structure has no sealing structure. After the vehicle has been running for a period of time, the anti-rust layer of the separation fork shaft and the bushing matching shaft section will wear out. In a humid and wading environment, the wear area is prone to rust, resulting in the rotation of the separation fork shaft and the bushing being blocked, and the release bearing cannot move up and down smoothly, resulting in incomplete clutch separation and easy jamming when selecting and shifting gears.

[0009] The release fork and the release fork shaft are connected by bolt clamping. After a long period of use, there are problems of mutual rotation and loosening. The release bearing cannot move up and down smoothly, resulting in incomplete clutch separation and easy jamming when selecting and shifting gears.

[0010] In summary, the separation fork shaft and bushing matching section of the traditional clutch release system structure are prone to rust, and the connection between the separation fork and the separation fork shaft is unstable, which leads to incomplete clutch release and easy jamming during gear selection and shifting.
