Description
Technical field
The utility model relates to a kind of automatic gap adjusting formula wheel cylinder that is used for automobile brake.
Background technique
Traditional wheel cylinder generally includes cylinder body, and the cylinder body two ends are respectively arranged with dust-proof cover; Be provided with active chamber in the cylinder body, the corresponding active chamber of cylinder body middle part is provided with oil inlet hole, and corresponding oil inlet hole two side positions are symmetrically arranged with two groups of piston assemblys in the active chamber; Be provided with leather cup between two groups of piston assemblys and the cylinder body, this kind design is because brake block is causing wearing and tearing after long-term the use; The gap can be increasing between brake block and the piston assembly, and therefore, the required stroke of piston assembly can become big; Thereby the formation potential faults very easily causes accident to take place.
Summary of the invention
To the deficiency that existing technology exists, it is a kind of simple in structure that the purpose of the utility model is to provide, the automatic gap adjusting formula wheel cylinder of reliable operation.
For realizing above-mentioned purpose, the utility model provides following technological scheme: a kind of automatic gap adjusting formula wheel cylinder comprises cylinder body; The cylinder body two ends are respectively arranged with dust-proof cover; Be provided with active chamber in the cylinder body, the corresponding active chamber of cylinder body middle part is provided with oil inlet hole, and corresponding oil inlet hole two side positions are symmetrically arranged with two groups of piston assemblys in the active chamber; Be provided with leather cup between two groups of piston assemblys and the cylinder body; Said two groups of piston assemblys are provided with annular collar respectively, and said annular collar is inboard to be fixedly connected with piston assembly, match through interference with the inwall of active chamber in the outside of annular collar.
Through adopting technique scheme, because the effect of annular collar, piston assembly has reduced the return stroke of piston assembly when resetting, thereby has regulated the gap between piston assembly and the brake block automatically, and then has eliminated potential faults.
The utility model further is provided with: said two groups of piston assemblys are provided with the boss to cylinder body middle part protrusion, and the inboard of said annular collar is fixedly connected with said boss.
Through adopting technique scheme, make the annular collar more stable work.
The utility model further is provided with: a side of the center tangent plane of said annular collar is the setting of " U " type; The relative piston assembly the other end of said boss is provided with limit dais; Said annular collar is set in the boss outside, and the two ends of annular collar compress setting with piston assembly and limit dais respectively mutually.
Through adopting technique scheme, annular collar can with more firm being connected of piston assembly, and annular collar and active chamber inwall have better frictional force, thus the effect of raising automatic gap adjusting.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model automatic gap adjusting formula wheel cylinder example structure figure.
Embodiment
Referring to accompanying drawing 1, the disclosed automatic gap adjusting formula of the utility model wheel cylinder comprises cylinder body 1; Cylinder body 1 two ends are respectively arranged with dust-proof cover 2; Be provided with active chamber 101 in the cylinder body 1, cylinder body 1 corresponding active chamber 101 middle parts are provided with oil inlet hole 102, and 102 liang of side positions of corresponding oil inlet hole are symmetrically arranged with two groups of piston assemblys 3 in the active chamber 101; Be provided with leather cup 4 between two groups of piston assemblys 3 and the cylinder body 1; Said two groups of piston assemblys 3 are provided with annular collar 5 respectively, and said annular collar 5 inboards are fixedly connected with piston assembly 3, match through interference with the inwall of active chamber 101 in the outside of annular collar 5.So be provided with, because the effect of annular collar 5, piston assembly 3 has reduced the return stroke of piston assembly 3 when resetting, thereby has regulated the gap between piston assembly 3 and the brake block automatically, and then has eliminated potential faults.
Present embodiment further is provided with: said two groups of piston assemblys 3 are provided with the boss 301 to cylinder body 1 middle part protrusion, and the inboard of said annular collar 5 is fixedly connected with said boss 301.So be provided with, make annular collar 5 more stable work.Present embodiment is further preferred; One side of the center tangent plane of said annular collar 5 is the setting of " U " type; Said boss 301 relative piston assembly 3 the other ends are provided with limit dais 302; Said annular collar 5 is set in boss 301 outsides, and the two ends of annular collar 5 compress setting with piston assembly 3 and limit dais 302 respectively mutually.So be provided with, annular collar 5 can with piston assembly 3 more firm being connected, and annular collar 5 has better frictional force with active chamber 101 inwalls, thereby improves the effect of automatic gap adjusting.
