Bar is fixed.
In work, hinge joint on clutch separation pawl and clutch housing as the first fulcrum, separate transition lever with
Hinge joint on clutch housing is as the second fulcrum, when clutch separation pawl walks downwards release travel in outer driving force effect
When, clutch separation pawl is tilted around the first fulcrum tail portion, and movement occurs therewith and tilts for tail support ring, separation transition lever and branch
Pushing out ring is equipped with the contact surface matched and separates at this time so that the external force by support ring rotates movement around the second fulcrum
The tail portion of transition lever moves down, and contacts with the cylindrical pin of lower section, and cylindrical pin is under the action of separating transition lever to moving down
It is dynamic, it acts in adjusting screw, adjusting screw is locked on clutch compressing disc by adjusting nut, so that clutch compressing disc is just
It is moved downwardly together with adjusting screw, realizes the separation of clutch compressing disc and friction plate；In engaging process, clutch compressing disc exists
Under the action of disk spring power, the axial opposite direction along clutch housing is moved, and realizes the engagement of clutch.
The clutch separation pawl is hinged on the lug of clutch housing, and separation transition lever is hinged on clutch housing
Lug on, be provided with and the support ring that separates transition lever one end and be in contact in the tail end of clutch separation pawl；It is arranged in this way
Purpose be: can be realized clutch separation pawl by the first fulcrum under primary lever actuation arm, as far as possible by clutch
The external force action of disengaging pawl front end is transmitted, and is achieved the effect that firm.
It is provided with cylindrical pin below the other end of the separation transition lever, cylindrical pin is through setting in clutch
Can slide axially on shell and under the action of separating transition lever along clutch housing, the lower section of cylindrical pin be mounted on
Adjusting screw head on clutch compressing disc is in contact, and the adjustment to adjust adjusting screw position is equipped in adjusting screw
Nut；The purpose being arranged in this way is: can be realized separation transition lever by the second fulcrum, under second lever actuation arm, to the greatest extent
The possible level-one external force action that will be received transmits, driving cylindrical pin movement, and then drives clutch compressing disc adjustment
Screw drives clutch compressing disc movement, realizes that clutch compressing disc separates from friction plate.
The utility model has the beneficial effects that
(1) the utility model lever can be good using the transmitting of circular arc point contact；
(2) the utility model keeps lever ratio basic in clutch separation process and cohesive process by second lever
It does not change, and is float design, it is not easy to movement interference, clamping stagnation occur；
(3) the utility model can shorten the thick stick of clutch separation pawl under the premise of clutch shaft arranges needs to large scale
Lever arm length avoids long cantilever design, enhances the intensity and use reliability of disengaging pawl；
