Description of drawings
By reference to the accompanying drawings, the utility model is further described:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is spacing structure drawing of device;
Accompanying drawing 3 is the utility model structural representation and the relative position in clutch actuating mechanism.
Among the figure: 1 is that shell, 2 is roller rolling retainer for the boss on the clutch actuating mechanism, 9 for positive stop end, 8 for limiting board, 7 for locking spring, 6 for pull bar, 5 for self-locking roller, 4 for end cap, 3.
Embodiment
Referring to accompanying drawing 1,2, a kind of clutch abrasion automatic compensator of the utility model comprises that shell 1, end cap 2, roller rolling retainer 9, self-locking roller 3, pull bar 4, locking spring 5, limiting board 6 and positive stop end 7 form.
A kind of clutch abrasion automatic compensator, it is comprised of shell, end cap, locking spring 5, self-locking roller 3, limiting board 6, pull bar 4.Described shell 1 and end cap 2 form an airtight containing space, and pull bar 4, roller rolling retainer 9, limiting board 6, locking spring 5, self-locking roller 3 all are included in the above-mentioned containing space.
When actuator moved to initial position, shell 1 can move freely, and realized the wear automatic-compensation of clutch under the effect of diaphragm spring power, and exported certain pulling force and provide pretightening force for release bearing.
As mentioned above, self-locking roller 3 is two, the symmetrical both sides that are arranged in pull bar 4, an end of described pull bar 4 have two symmetries, be splay wedge surface.Locking spring 5 is in compressive state always when normality so that self-locking roller 3 has the trend that moves to wedge surface, and so that self-locking roller 3 contact with limiting board 6.Described pull bar 4 is when moving to the clutch separation direction, and the self-locking roller 3 of wedging drives shell 1 and moves together.
In order to realize above-mentioned requirements, at the inwall of clutch actuating mechanism one outstanding boss 8 is arranged.When clutch actuating mechanism was in original state, the positive stop end 7 in the limit stoper contacted with boss 8 on the clutch actuating mechanism, limits its further motion; The other end contacts with self-locking roller 3.
When clutch actuating mechanism carried out separating action at the band dynamic clutch, reducing gear drove pull bar 4 actions.Formation self-locking after pull bar 4 touches self-locking roller 3, pull bar 4, roller rolling retainer 9, self-locking roller 3, locking spring 5, limiting board 6, positive stop end 7 and shell 1, end cap 2 become one, and drive the drag-line cut-off clutch.
When clutch actuating mechanism carried out the combination action at the band dynamic clutch, reducing gear drove pull bar 4 action in the other direction.The self-locking body that pull bar 4, roller rolling retainer 9, self-locking roller 3, locking spring 5, limiting board 6, positive stop end 7 and shell 1, end cap 2 form is towards the direction motion of clutch combination.Owing to just can not move again when the existence of boss 8, the positive stop end 7 in the limit stoper move to the position of boss 8.Limited limit stoper drives self-locking roller 3 and breaks away from self-locking, thereby realizes auto-compensation.
Clutch wearing and tearing occur after long-time the use, the clutch actuating mechanism complete combination of clutch, clutch are rubbed spring force imbalance that flat spring power and locking spring 5 produce.Shell 1 and end cap 2 just can be under clutch rubs the effect of flat spring power towards the direction motion of clutch combination, the spring force rebalancing that flat spring power and locking spring 5 produce until rub, compensation mechanism all can attempt carrying out wear compensation at every turn in conjunction with clutch.
Be arranged in the locking spring 5 in the containing space, not only can play the effect of locking self-locking roller 3, can also play the effect that pretightening force is provided.Described locking spring 5 one ends act on the internal surface of end cap 2, and the other end acts on the roller rolling retainer 9.When the clutch compensation mechanism was in initial mounting point, described locking spring 5 was in compressive state, and its power still can not overcome the flat spring power of rubbing, and active force passes to the clutch separation rocking arm by shell 1, thereby played the effect of pretightening force.
It should be noted last that: above embodiment is only unrestricted in order to the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the utility model, and not breaking away from spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
