Abstract
The utility model discloses a buffer structure for a push rod of a clutch master cylinder. The buffer structure comprises a push rod, the front end of the push rod is arranged at the end of a piston in a supporting manner, the rear end of the push rod is in threaded connection with a connecting nut, the connecting nut is extended into a push rod fork shell, the front end of the connecting nut is matched with a step on the inner wall of the push rod fork shell, and a rubber buffer pad is cushioned between the rear end of the connecting nut and the inner wall of the push rod fork shell. In the utility model, an on-off valve positioned in the piston replaces a compensation hole, boning and deburring procedures can be omitted due to no compensation hole, and the processing cost is low; and friction between a main leather cup and the compensation hole is avoided, so that the main leather cup is not easily worn, and the service life of the main leather cup is prolonged.
Description
Technical field
The utility model relates to a kind of push rod buffer structure of clutch master cylinder.
Background technique
The car clutch master cylinder is to convert clutch-pedal load to hydraulic pressure to output to clutch slave cylinder, and clutch slave cylinder changes hydraulic rotation into thrust, makes clutch realize separating.During motorist's let slip the clutch, push rod promotes total pump piston increases oil pressure, enters wheel cylinder by flexible pipe, forces minute pump rod to promote withdrawal fork, before release bearing is pushed to; When motorist's release the clutch pedal, hydraulic pressure is removed, and withdrawal fork is return original position gradually under the return spring effect, and clutch is in again jointing state.
In the prior art, because the primary cup design is unreasonable, the friction between primary cup and the compensate opening makes primary cup be easy to wearing and tearing, has reduced working life.
The model utility content
The purpose of this utility model provides a kind of push rod buffer structure of clutch master cylinder, and this clutch master cylinder has replaced compensate opening with the on-off valve that is positioned at piston, owing to there not being compensate opening, has saved the honing deburring operation, and processing cost is low; Avoid the friction between primary cup and the compensate opening, made primary cup not easy to wear, improved working life.
The technical solution of the utility model is as follows:
A kind of push rod buffer structure of clutch master cylinder, include push rod, the front end overhead of push rod is in the end of piston, the rear end scyewed joint of push rod has the attaching nut, the attaching nut extend in the push rod fork housing, attaching nut's front end cooperates with push rod fork inner walls step, is equipped with rubber buffer between attaching nut's rear end and the push rod fork inner walls.
The end of described push rod is connected with locking nut, and the locking nut overhead is on push rod fork hull outside wall.
The utility model has replaced compensate opening with the on-off valve that is positioned at piston, owing to there not being compensate opening, has saved the honing deburring operation, and processing cost is low; Avoid the friction between primary cup and the compensate opening, made primary cup not easy to wear, improved working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of push rod buffer structure of clutch master cylinder, include push rod 1, the front end overhead of push rod 1 is in the end of piston, and the rear end scyewed joint of push rod 1 has attaching nut 3, and attaching nut 3 extend in the push rod fork housing 4, attaching nut 3 front end cooperates with push rod fork housing 4 inwall steps, be equipped with rubber buffer 5 between attaching nut 3 rear end and push rod fork housing 4 inwalls, the end of push rod 1 is connected with locking nut 2, and locking nut 2 overheads are on push rod fork housing 4 outer side walls.
