Abstract
The utility model relates to a clutch booster with the cleaning function, which includes a piston cylinder body, wherein an oil inlet pipe is arranged on the piston cylinder body; an oil inlet joint provided with an axial oil inlet port is arranged at the end part of the oil inlet pipe; and a filter screen fitted with the oil inlet port is detachably fixed in the oil inlet port of the oil inlet joint. Through arrangement and installation of the filter screen on the oil inlet port, the clutch booster can prevent impurities in hydraulic oil from entering an inner cavity of the cylinder body, so as to avoid the problem about failure of the clutch booster with the cleaning function caused by abrasion, and further improve the service life of the clutch booster with the cleaning function; at the same time, the filter screen is simple in structure and low in processing cost, so that the improvement cost of the clutch booster can be reduced greatly.
Description
Technical field
The utility model relates to a kind of clutch booster that uses on the automobile in the mechanical field, especially relates to a kind of clutch booster with cleaning function.
Background technique
At present; When the driver steps on the clutch pedal of automobile; The hydraulic oil that extrudes from clutch master cylinder can get into the inner chamber of cylinder body through the filler opening that the cylinder body of clutch booster is offered, and along with the increase of pedal travel, the oil mass that gets into inner chamber of cylinder block can increase gradually.Simultaneously; Hydraulic oil has the impurity that carries also can get into the inner chamber of piston cylinder cylinder body along with hydraulic oil, and along with the continuous increase of oil mass, impurity can get in the piston of clutch booster; Thereby make the inefficacy that is worn of Sealing on the piston, and then cause the clutch booster reduction in working life.
The model utility content
The utility model provides a kind of clutch booster, be intended to solve the problem that the impurity in the hydraulic oil gets into the inner chamber of piston cylinder cylinder body in the existing technology through filler opening with cleaning function.
The technological scheme of the clutch booster of this band cleaning function is following:
A kind of clutch booster with cleaning function; Comprise the piston cylinder cylinder body; Said piston cylinder cylinder body is provided with oil inlet pipe, and the end of said oil inlet pipe is a fuel inlet fitting of offering the axial fuel inlet hole, is removably fixed with the filter screen that coincide with oil inlet hole in the oil inlet hole of said fuel inlet fitting.
Said oil inlet hole has the taper hole section of big footpath near the outer end of said fuel inlet fitting, and said filter screen periphery is provided with the conical structure with the hollow shape of said taper hole section cone match.
The utility model makes the impurity in the hydraulic oil can not get into the inner chamber of cylinder body through installing filter screen on fuel inlet fitting; Thereby the problem that the piston seal of having avoided the clutch booster of band cleaning function is worn and lost efficacy, and then the working life of improving the clutch booster of band cleaning function.Simultaneously, be dismountable the fixed connection between filter screen and the fuel inlet fitting, thus make filter screen installation and clean convenient, and because filter screen simple in structure, low processing cost, thereby make the improvement cost of clutch booster reduce greatly.
Description of drawings
Fig. 1 is the assembling schematic representation of filter screen on cylinder body among the embodiment of the utility model;
Fig. 2 is the structural representation of filter screen among Fig. 1.
Embodiment
The embodiment of the clutch booster of band cleaning function: as depicted in figs. 1 and 2; The clutch booster of this band cleaning function comprises piston cylinder cylinder body 2, and cylinder body 2 is provided with oil inlet pipe, and the oil inlet pipe end is a fuel inlet fitting; Oil inlet hole 3 internal fixation of fuel inlet fitting have removable filter net 1; Just filter screen 1 is through the hollow cone structure 1-1 on its periphery and the taper hole section 3-1 cone match of oil inlet hole 3, and wherein, the bigger diameter end of taper hole section 3-1 is near the outer end of fuel inlet fitting; Thereby make in use; This filter screen 1 is in the taper hole section of oil inlet hole 3 through the conical structure 1-1 of its outer peripheral portion, and can not slip into along the inwall of oil inlet hole 3 in the inner chamber of cylinder body 2, and when needs clean filter screen; Can use the instrument of end band barb that filter screen is taken out, just filter screen can be pulled down from fuel inlet fitting very easily.
In addition; The taper hole section also can use the step surface that protrudes on the hole wall of oil inlet hole to replace; Thereby make the hollow cone structure of periphery of filter screen also can use annular tubular structure to replace; Just the annular tubular structure of filter screen periphery or filter screen body overlap on this step surface, thereby guarantee to be fixed on the detachable requirement of the filter screen in the fuel inlet fitting.
Claims (2)
1. clutch booster with cleaning function; Comprise the piston cylinder cylinder body; Said piston cylinder cylinder body is provided with oil inlet pipe; The end of said oil inlet pipe is a fuel inlet fitting of offering the axial fuel inlet hole, it is characterized in that: be removably fixed with the filter screen that coincide with oil inlet hole in the oil inlet hole of said fuel inlet fitting.
2. the clutch booster of band cleaning function according to claim 1; It is characterized in that: said oil inlet hole has the taper hole section of big footpath near the outer end of said fuel inlet fitting, and said filter screen periphery is provided with the conical structure with the hollow shape of said taper hole section cone match.
