For achieving the above object, the utility model provides following technical scheme: the master brake cylinder that a kind of safety performance is high, comprise pull back spring, cylinder body, brake chamber, primary cup, reservoir compartment, fuel inlet fitting, positioning spacer, oil sealing end cap, piston, push rod, secontary cup, compensation orifice, fuel tap, fuel tap spring, oil outlet, described cylinder body is provided with oil outlet, described oil outlet is connected to fuel tap, fuel tap spring, in the cavity that described oil sealing end cap and cylinder body are formed, piston is installed, between described cylinder body and oil sealing end cap, positioning spacer is installed, cavity is separated into brake chamber and reservoir compartment by described positioning spacer, described piston is axially across oil sealing end cap and stretch in the brake chamber of cylinder body, in described brake chamber, pull back spring is installed, described piston is provided with compensation orifice and is connected to primary cup, described cylinder body is provided with the fuel inlet fitting be communicated with reservoir compartment, primary cup is provided with in described brake chamber secontary cup, described push rod is connected to piston on the left of cylinder body.
Preferably, described push rod front end is quality of rubber materials.
Preferably, described secontary cup is between positioning spacer and oil sealing end cap.
Compared with prior art, the beneficial effects of the utility model are: compared with prior art, this master brake cylinder simplifies the loaded down with trivial details principle of work of most of master brake cylinder, by fuel inlet fitting and brake chamber integration, save space, reduced productive costs, and eliminate the valve metal film of the axially extending bore of primary cup and positioning spacer, primary cup is directly arranged on piston, not only simplifies principle of work, also reduce productive costs.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the master brake cylinder that a kind of safety performance is high, comprise pull back spring 1, cylinder body 2, brake chamber 3, primary cup 4, reservoir compartment 5, fuel inlet fitting 6, positioning spacer 7, oil sealing end cap 8, piston 9, push rod 10, secontary cup 11, compensation orifice 12, fuel tap 13, fuel tap spring 14, oil outlet 15, described cylinder body 2 is provided with oil outlet 15, and described oil outlet 15 is connected to fuel tap 13, fuel tap spring 14, in the cavity that described oil sealing end cap 8 and cylinder body 2 are formed, piston 9 is installed, between described cylinder body 2 and oil sealing end cap 8, positioning spacer 7 is installed, cavity is separated into brake chamber 3 and reservoir compartment 5 by described positioning spacer 7, described piston 9 is axially across oil sealing end cap 8 and stretch in the brake chamber 3 of cylinder body, in described brake chamber 3, pull back spring 1 is installed, described piston 9 is provided with compensation orifice 12 and is connected to primary cup 4, described cylinder body 2 is provided with the fuel inlet fitting 6 be communicated with reservoir compartment 5, primary cup 4 is provided with in described brake chamber 3 secontary cup 11, described push rod 10 is connected to piston 9 on the left of cylinder body 2, and described secontary cup 11 is between positioning spacer 7 and oil sealing end cap 8.
Preferably, described push rod 10 front end is quality of rubber materials.
Principle of work of the present utility model is: when not working, and the compensation orifice 12 of piston 9 is bottom primary cup 4.When causing the pucker & bloat of the braking liquid of brake chamber 3 and reservoir compartment 5 because of leakage or temperature Change, balance is maintained by compensation orifice 12 and fuel feed hole, during braking, promote push rod 10 and then promote piston 9, after primary cup 4 covers compensation orifice 12, hydraulic pressure in brake chamber 3 starts to set up, after the pressure of brake chamber 3 inside brake liquid overcomes the elastic force of fuel tap spring 14 of oil outlet 15, after pushing fuel tap open, braking liquid is delivered to wheel cylinder, after brake off, pedal gear, piston 9, wheelcylinder piston be return under respective pull back spring effect.
