Abstract
The utility model discloses a clutch master pump piston assembly with a guiding structure. The clutch master pump piston assembly comprises a piston and a cylinder body, wherein the piston is in clearance fit with an inner cavity of the cylinder body, the front end and the rear end of the piston are provided with leather bowls, and the rear end of the piston is provided with a ball socket. The clutch master pump piston assembly is characterized in that a guiding device is arranged between the rear end of the piston and the inner cavity of the cylinder body. Since the guiding device is arranged between the rear end of the piston and the inner cavity of the cylinder body, the structure is compact, the sealing performance is good, the clutch master pump piston assembly is kept in a stable situation while working, the stability is increased, and the service life is prolonged.
Description
Technical field
The utility model belongs to the technical field of the clutch master cylinder piston of auto manufacturing, particularly a kind of clutch master cylinder piston assembly with guide structure.
Background technique
Existing clutch master cylinder piston assembly comprises piston and cylinder body; The front end and back end of piston is provided with leather cup; The piston of clutch master cylinder piston assembly moves reciprocatingly in cylinder body, when clutch master cylinder is worked, when push rod acts on the ball-and-socket of piston rear end portion; Piston can cause extruding to cylinder body; Behind the certain number of times of the inherent work of piston and cylinder body wearing and tearing to a certain degree can be arranged all like this, the roughness of the endoporus of cooperation and axle also can be worse and worse, can wear and tear at long duration of action lower cylinder body inwall and piston and cause assembly failure.
The model utility content
The purpose of the utility model is the deficiency to said structure, provide a kind of simple in structure, cooperate compact, use the clutch master cylinder piston assembly with guide structure reliable, that the life-span is long.
The technological scheme that technical problem adopted that the utility model solves is:
A kind of clutch master cylinder piston assembly with guide structure; Comprise piston and cylinder body, piston and inner chamber of cylinder block Spielpassung, the front end and back end of piston all is provided with leather cup; The rearward end of piston is provided with ball-and-socket, it is characterized by between rear end and the inner chamber of cylinder block of piston and is provided with guiding device.
In the practical implementation, above-mentioned piston is provided with groove, and guiding device is a guide ring, and guide ring is set in the groove of piston, and guide ring and clutch master cylinder piston assembly are suitable.
In the practical implementation, described guide ring is the POM guide ring, and POM claims polyoxymethylene again, is a kind of engineering plastics of function admirable, and the title of " taking steel by force ", " supersteel " is arranged abroad.Pom has hardness, intensity and the rigidity of metalloid, in very wide temperature and humidity scope, all has good self lubricity, good fatigue resistance, and springiness, and it also has chemical-resistant preferably in addition.
On the rear end of piston, be provided with a guiding device, its advantage has been good guidance quality, has strengthened the stationary performance of piston motion, has improved the life-span of clutch master cylinder piston assembly.Guiding device is a guide ring, and guiding device is on piston, to have designed a guide ring, and guide ring is selected the good material of wear-resisting property for use.The utility model is loaded onto a guide ring on piston; Piston is when carrying out axially reciprocating like this, and the gap of piston and inner chamber of cylinder block can be directed to ring and support, and has avoided the rigidity friction between piston and the inner chamber of cylinder block effectively; Add that guide ring selects the good material of wear-resisting property for use; Very wear-resisting, make the utility model can remain on very stable status like this, also improved the working life of clutch master cylinder piston assembly greatly.
The beneficial effect of the utility model is: the utility model is owing to be provided with guiding device between the rear end of piston and inner chamber of cylinder block, compact structure, and good airproof performance remains on very stable status during work, improved stability and working life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment model utility is further specified.
Fig. 1 is the utility model example structure schematic representation.
Fig. 2 is the structural representation of the utility model embodiment piston assembly.
Among the figure: 1, piston 2, cylinder body 3, leather cup 4, ball-and-socket 5, guide ring.
Embodiment
In Fig. 1 and Fig. 2, a kind of clutch master cylinder piston assembly with guide structure comprises piston 1 and cylinder body 2; Piston 1 and cylinder body 2 inner chamber Spielpassung; The front end and back end of piston 1 all is provided with leather cup 3, and the rearward end of piston 1 is provided with ball-and-socket 4, is provided with guiding device between the rear end of piston 1 and cylinder body 2 inner chambers; Guiding device is a guide ring 5, and guide ring 5 adopts the POM material.
The utility model is loaded onto a guide ring 5 on piston 1; Piston 1 is when carrying out axially reciprocating like this, and the gap of piston 1 and cylinder body 2 inner chambers can be directed to ring 5 and support, and has avoided the rigidity friction between piston 1 and cylinder body 2 inner chambers effectively; Add that guide ring 5 selects the good material of wear-resisting property for use; Very wear-resisting, what make the utility model like this can remain on very stable status, has also improved the working life of clutch master cylinder piston assembly greatly.
The foregoing description is the explanation to the utility model, is not the qualification to the utility model, and any structure after simple transformation on the utility model basis all belongs to the protection domain of the utility model.
