Summary of the invention
Technical problem to be solved in the utility model is that a kind of hydraulic brake system that has the air pressure exhaust gear is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of hydraulic brake system, but comprise brake unit control gas supply pressure device and air cock; But described control gas supply pressure device is connected on the hydraulic pressure cup of described brake unit, is used for providing air pressure to the hydraulic pressure cup and acts on hydraulic oil in the hydraulic pressure cup; Described air cock is arranged on each brake cylinder of described brake unit.
The beneficial effects of the utility model are: but force hydraulic oil in the hydraulic pressure cup to compress into the master brake cylinder of brake unit fast by the air pressure that the control gas supply pressure device provides, under the impetus of the inner carrier of master brake cylinder, fast the gas in the pipeline between master brake cylinder and each brake cylinder is pressed in each brake cylinder by hydraulic oil, forms gas wall one.When the hydraulic oil in the hydraulic pressure cup no longer descends, open the air cock on each brake cylinder, gas will be discharged fast.When hydraulic oil flows out air cock, show that then the gas in the hydraulic brake system has been discharged totally.Obviously, the utility model can be clean with the gaseous emission in the brake unit owing to being provided with controllable pressure device and air cock, the exhaust efficiency height, and manipulation strength is low, and is simple in structure, easy to manufacture, with low cost, safe and reliable; Assembling easily, convenient disassembly, suitable applying.
Description of drawings
Fig. 1 is the assembly decomposing schematic representation of a kind of embodiment of the utility model;
Fig. 2 is the assembly integral installation scheme drawing of a kind of embodiment of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, a kind of hydraulic brake system, but comprise brake unit control gas supply pressure device and air cock 9,12.But the control gas supply pressure device is connected on the hydraulic pressure cup 7 of brake unit, is used for providing air pressure to hydraulic pressure cup 7 and acts on hydraulic oil in the hydraulic pressure cup 7; Air cock 9 is arranged on the front wheel brake wheel cylinder 10 of brake unit, and air cock 12 is arranged on the trailing wheel brake cylinder 11 of brake unit.
Specifically, in the present embodiment, but the control gas supply pressure device comprises air inlet pipe 2 and compressed air source unit; Air inlet pipe 2 has first end and second end, and this first end is connected on the compressed air source unit 1, and this second end is connected on the hydraulic pressure cup 7 of brake unit.Second end of air inlet pipe 2 and the junction between the hydraulic pressure cup 7 are provided with gas operated device 4, and an end of this gas operated device 4 interts on the bowl cover 6 of hydraulic pressure cup 7, by bowl cover 6 is tightened on the hydraulic pressure cup 7, thereby gas operated device 4 are connected on the hydraulic pressure cup 7; The other end of gas operated device 4 inserts in second end of air inlet pipe 2, and like this, the gas in the compressed air source unit 1 flows into hydraulic pressure cup 7 through air inlet pipe 2 and gas operated device 4.Control gaseous flows into hydraulic pressure cup 7 from compressed air source unit 1 for convenience, is provided with valve switch 3 on air inlet pipe 2.In order to prevent that from there is gas leakage the junction between air inlet pipe 2 and the hydraulic pressure cup 7, the junction between air inlet pipe 2 and hydraulic pressure cup 7 is provided with sealing member 5; Sealing part 5 is a rubber pad, is set on the gas operated device 4; The both ends of sealing member 5 form with second end of hydraulic pressure cup 7 and air inlet pipe 2 respectively and are sealed and matched.
The working process of present embodiment is: open valve switch 3, allow the high pressure gas in the compressed air source unit 1 flow into hydraulic pressure cups 7 through air inlet pipe 2, gas operated device 4, the high pressure gas that flow into hydraulic pressure cup 7 force the hydraulic oil in the hydraulic pressure cup 7 to compress into the master brake cylinder 13 of brake unit fast.Under the impetus of the inner carrier of master brake cylinder 13, fast the gas in the pipeline between the pipeline 8 between master brake cylinder 13 and the front wheel brake wheel cylinder 10, master brake cylinder 13 and the trailing wheel brake cylinder 11 8 is pressed in front wheel brake wheel cylinder 10 and the trailing wheel brake cylinder 11 by hydraulic oil, forms gas wall one.When the hydraulic oil in the hydraulic pressure cup 7 no longer descends, shut valve switch 3, open air cock 9 on the front wheel brake wheel cylinder 10 and the air cock 12 on the trailing wheel brake cylinder 11 again, gas will be discharged fast.In the operating process of gas, this control step can repeat in the bleeder brake unit, when hydraulic oil flows out air cock 9 and air cock 12, shows that then the gas in the brake unit has been discharged totally.Obviously, the utility model can be clean with the gaseous emission in the brake unit owing to being provided with controllable pressure device and air cock, the exhaust efficiency height, and manipulation strength is low, and is simple in structure, easy to manufacture, with low cost, safe and reliable; Assembling easily, convenient disassembly, suitable applying.
Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
