Technical field
The utility model relates to the master brake cylinder that uses in a kind of brake system of car.
Background technology
The fuel inlet fitting of common master brake cylinder is installed in fuel inlet fitting on the pump housing with the oil-feed screw, junction between the oil-feed head and the pump housing uses packing seal to seal, adopt such sealing structure poor-performing, master brake cylinder repairing poor performance, the integral stop performance descends.
The utility model content
Technical problem to be solved in the utility model provides a kind of master brake cylinder of favorable sealing property.
For solving the problems of the technologies described above, the technical solution of the utility model is: master brake cylinder, comprise the pump housing, on the described pump housing fuel inlet fitting is installed, the described pump housing is provided with the fuel inlet fitting spliced eye, described fuel inlet fitting is provided with the Plug Division that cooperates with described fuel inlet fitting spliced eye, is provided with rubber sealing boot in the slit between described Plug Division and the described fuel inlet fitting spliced eye; Be provided with the fuel inlet fitting securing device between the described fuel inlet fitting and the described pump housing.
As optimized technical scheme, described fuel inlet fitting securing device comprises the mounting flange that is fixedly installed on the described fuel inlet fitting, described mounting flange near and perpendicular to described Plug Division, fix by tightening screw between the described mounting flange and the described pump housing.
As optimized technical scheme, described fuel inlet fitting securing device comprises the mounting flange that is fixedly installed on the described fuel inlet fitting, described mounting flange near and perpendicular to described Plug Division, also be provided with fixed plate on the described mounting flange, described fixed plate, described mounting flange and the described pump housing are fixed by tightening screw.
As optimized technical scheme, described fuel inlet fitting in a tubular form, described fuel inlet fitting end is bent to form described Plug Division, and described mounting flange is arranged on the bending place of described fuel inlet fitting, and the part outside face of described fuel inlet fitting and described mounting flange connect as one.
Owing to adopted technique scheme, master brake cylinder, comprise the pump housing, on the described pump housing fuel inlet fitting is installed, the described pump housing is provided with the fuel inlet fitting spliced eye, described fuel inlet fitting is provided with the Plug Division that cooperates with described fuel inlet fitting spliced eye, is provided with rubber sealing boot in the slit between described Plug Division and the described fuel inlet fitting spliced eye; Be provided with the fuel inlet fitting securing device between the described fuel inlet fitting and the described pump housing; Effectively improve the leak tightness at fuel inlet fitting place, strengthened the repairing performance of brake pump, reduced brake response time, increased insensitivity greatly, reduced stopping distance, improved safety performance.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 be among Fig. 1 A to view;
Fig. 3 be among Fig. 1 C to view.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, master brake cylinder, comprise the pump housing 1, be provided with piston 8 in the described pump housing 1, described piston 8 front portions are equipped with primary cup 9, described piston rear portion is equipped with secontary cup 6, the front portion is provided with cylinder hole 11 in the described pump housing, be provided with piston return spring 10 between described cylinder hole 11 and the described piston 8, on the described pump housing 1 fuel inlet fitting 2 is installed, the described pump housing 1 is provided with fuel inlet fitting spliced eye 5, described fuel inlet fitting 2 is provided with the Plug Division 13 that cooperates with described fuel inlet fitting spliced eye 5, be provided with rubber sealing boot 4 in the slit between described Plug Division 13 and the described fuel inlet fitting spliced eye 5, be provided with the fuel inlet fitting securing device between the described fuel inlet fitting 2 and the described pump housing 1, described fuel inlet fitting securing device comprises the mounting flange 14 that is fixedly installed on the described fuel inlet fitting 2, described mounting flange 14 near and perpendicular to described Plug Division 13, also be provided with fixed plate 3 on the described mounting flange 14, described fixed plate 3, the described mounting flange 14 and the described pump housing 1 are fixing by tightening screw 12.Described fuel inlet fitting 2 in a tubular form, described fuel inlet fitting 2 ends are bent to form described Plug Division 13, described mounting flange 14 is arranged on the bending place of described fuel inlet fitting 2, and the part outside face of described fuel inlet fitting 2 and described mounting flange 14 connect as one.The described piston 8 rear portions push rod 7 outer with extending to the pump housing is connected.
During off working state,, be loaded with braking liquid in the pump housing 1 inner chamber by the connection of fuel inlet fitting 2.
During work, external force is applied on the push rod 7, push rod 7 promotes piston 8 and moves in the pump housing 1, piston 8 moves past forward in the journey, and when primary cup 9 passed through compensation orifice, the pump housing 1 inner chamber was divided into pressure chamber and common pressure chamber by primary cup 9, piston 8 continues the reach braking, the pump housing 1 pressure chamber is set up the required pressure of brake piping, and this moment, braking liquid flowed along pipeline, participates in next step the braking procedure to go.
Above-described only is preferred implementation of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; can also make some distortion and improvement; for example: change the mounting means that position, change fixed plate be set of mounting flange on fuel inlet fitting etc., this also should be considered as protection domain of the present utility model.
