Abstract
The utility model relates to a master pump, in particular to an automobile brake master pump, which mainly comprises a driving valve body, a connecting pipe, an electromagnetic valve, a relay valve body, a tappet rod, a driving piston, a driving valve, a relay piston, a relay valve, an exhaust gear seat, a normal ventilation opening and a brake gas opening, and is characterized in that a sealing slide plate is sheathed on the driving piston, a gas inlet of the electromagnetic valve is communicated onto the normal ventilation opening of a pump body, and a gas outlet is communicated onto a pump body opening arranged between the driving piston and the sealing slide plate. The brake operation and control is convenient, the effect is good, the braking is firm without locking, automobile hubs are not easy to damage during heavy loading, wheels are not easy to lock during light loading or idle loading, and the deformity and the abrasion of tires cannot be easily caused; and in addition, the safety performance of the automobile can be greatly improved, the potential safety hazards are greatly eliminated, and traffic accidents can be greatly reduced. The automobile brake master pump belongs to a product with the advantages of high cost performance, economy, substantial benefits and obvious social benefits.
Description
Technical field
The present invention relates to a kind of master cylinder, particularly a kind of automobile brake general pump.
Background technology
Present automobile brake general pump, otherwise heavy, bounce is big, and the pedal that gently touches on the brake is reaction not, must firmly trample brake pedal, and braking is roughly; During loaded vehicle, damage nave boss easily, when light car or empty wagons, wheel is prone to locking, causes the wearing and tearing of tire deformity, and side force increases the easy sideslip of direction behind the wheel lockup simultaneously.Lighter, during loaded vehicle, braking effect is preferable, but when light car or empty wagons, wheel more is prone to locking, is a kind of automatically controlled adjustable master cylinder Chinese patent of ZL200820133245.1 like the patent No..So existing automobile brake general pump is difficult for controlling, braking effect is poor, and there is potential safety hazard in poor safety performance.
Summary of the invention
To above problem, the purpose of this invention is to provide a kind of automobile brake general pump of being convenient to control.
A kind of automobile brake general pump of being convenient to control; Comprise driving valve body, connection pipe, electromagnetic valve, relay valve body, tappet, driven plunger, driving valve, relay piston, servo valve, exhaust block seat, normal open gas port and braking gas port, it is characterized in that: on driven plunger, be set with drop bar; The admission port of electromagnetic valve is communicated with on the normal open gas port of the pump housing, and air extractor duct is communicated with on the pump housing opening between driven plunger and drop bar.
The objective of the invention is through on driven plunger, being set with drop bar, and realize on normal open gas port that the admission port and the air extractor duct of electromagnetic valve is connected to the pump housing and the pump housing opening between driven plunger and drop bar; Promptly utilize the crank motion automatically regulating brake weight of switch electromagnetic valve and drop bar, so that control.So not only brake is controlled conveniently, and is effective, stop firm not locking again, during loaded vehicle, easy damaged nave boss not, when light car or empty wagons, wheel is difficult for locking, is difficult for causing the wearing and tearing of tire deformity; And can improve the safety performance of automobile greatly, and eliminate safe hidden trouble greatly, can significantly reduce traffic accident, be that a kind of cost performance is high, economical and practical, the tangible product of social benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is that the C-C of Fig. 1 is to cutaway view
Fig. 3 is that the C-C of Fig. 1 is to another kind of state cutaway view.
Among the figure: drive valve body 1, connection pipe 2, drive brake gas port 3, electromagnetic valve 4, driving normal open gas port 5, servo braking gas port 6, servo normal open gas port 7, relay valve body 8, tappet 9, driven plunger 10, driven plunger interstage sleeve 11, drop bar 12, driving body valve 13, relay piston 14, servo body valve 15, exhaust block seat 16, pull back spring 17, back-up ring 18, spacing jump ring 19.
The specific embodiment
Detail below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a kind of automobile brake general pump of the present invention, and Fig. 2 and Fig. 3 open the structure graph of electromagnetic valve when closing electromagnetic valve.Mainly comprise driving valve body 1, connection pipe 2, electromagnetic valve 4, relay valve body 8, tappet 9, driven plunger 10, driving body valve 13, relay piston 14, servo body valve 15, exhaust block seat 16, normal open gas port and braking gas port, main points are: on driven plunger 10, be set with drop bar 12; The admission port of electromagnetic valve 4 is communicated with on the normal open gas port of the pump housing, and air extractor duct is communicated with on the pump housing opening of 12 of driven plunger 10 and drop bars.Electromagnetic valve 4 usefulness connection pipes 2 among the figure are communicated with on the pump housing opening of 12 of the normal open gas port of the pump housing and driven plunger 10 and drop bars.Through utilizing switch electromagnetic valve 4 to make drop bar 12 displacement come the automatically regulating brake weight, make it rationally appropriate, so that control, stop firmly and be difficult for locking.
For the ease of drop bar 8 is installed, the master cylinder among the figure also comprises driven plunger interstage sleeve 11.
During loaded vehicle; Open electromagnetic valve 4; Pneumatic pipe cleaner is crossed and is communicated with 12 of driven plunger 10 and the drop bars that drives the electromagnetic valve 4 entering pump housings on the pump housing opening of normal open gas port 5 and driven plunger 10 and 12 of drop bars at the pump housing respectively; Drop bar 12 is pressed down, and compression retracteding position spring 17 (as shown in Figure 2); So in loaded vehicle when brake, is not only light and stop firmly.During light car, close electromagnetic valve 4, under the effect of pull back spring 17, drop bar 12 reset (as shown in Figure 3); So, not only stop firmly during light car brake and be difficult for locking.
