Abstract
The utility model relates to a plunger type brake master cylinder assy being matched with an anti-locked braking system (ABS), which belongs to the technical field of automobile brakes. A first cavity primary cup, a second cavity primary cup, a first cavity secondary cup and a second cavity secondary cup are fixedly connected with a cup groove of a main cylinder body, a first spring part is arranged on a first piston part, a second spring part is arranged on a second piston part, the first piston part and the second piston part are connected with each other in the main cylinder body in series, and sixteen small holes are respectively arranged in the first and the second piston parts. The utility model has the advantages that: the plunger type brake master cylinder assy has a novel and simple structure, less numbers and types of component parts and wide application scope, is suitable for various automobile models which are provided with the ABS, particularly the automobile models with large product stroke and smaller assembly space of a finished automobile, the flows of the brake cavity and the normal-pressure cavity of the brake master cylinder assy with the structure is greatly larger than that of a center valve type brake master cylinder, so the required flow of the ABS can be satisfied.
Description
Technical field
The utility model belongs to the automobile brake technical field, refers in particular to a kind of plunger tpe brake master cylinder assembly that can be applicable to mate the ABS system.
Background technology
Brake master cylinder assembly is the critical component in the brake system of car, and its main effect is braking force to be changed into the hydraulic pressure form finally realize braking function.
The ABS system adjusts braking force at any time according to the wheel situation, prevents wheel lockup.Pressure regulator among the ABS is an actr, hydraulic pressure or air pressure that its command signal control brake master cylinder that transmits according to electronic control package provides to brake wheel cylinder, thereby control wheel velocity.It is not controlled by chaufeur when the pressure of automatically regulating master cylinder or air chamber.It is contained between master brake cylinder and the wheel wheel cylinder; Thereby the impulse form so that per second is about 4～10 times is carried out brake-pressure regulation; Make the wheel cylinder of each wheel can realize increased pressure, the function that pressure keeps and pressure reduces,, guaranteed the stability of glancing impact automobile to greatest extent to bring into play the brake system braking force and to prevent wheel lockup as far as possible; Increase the sense of security, shortened stopping distance and braking time.
This shows,, require the brake-pressure of master brake cylinder to change fast because ABS is to the regulatory function of brake cylinder pressure and powerful regulating frequency thereof, can fast run-up pressure and step-down, just require in the master brake cylinder brake fluid flow big.
Summary of the invention
The utility model provides a kind of plunger tpe brake master cylinder assembly that is applied to mate the ABS system, and the total length of the conventional central valve formula master brake cylinder of stroke is excessive greatly to solve at present, takies the bigger problem in car load space.
The technical scheme of the utility model is: the first chamber primary cup, the second chamber primary cup, the first chamber secontary cup, the second chamber secontary cup are captiveed joint with the leather cup groove of Master cylinder body; First spring members is arranged on the first piston parts; Second spring members is arranged on second piston element; First piston parts, second piston element are connected in the Master cylinder body, and 16 apertures are respectively arranged above.
The advantage of the utility model is: novel structure, succinct; The quantity and the kind of component part are less; Applied range is suitable for various vehicles of mating ABS, especially big, the less vehicle of car load assembly space of product stroke; The flow of this structure brake master cylinder assembly brake chamber and common pressure chamber can satisfy the desired flow of ABS system much larger than central valve formula master brake cylinder.

Fig. 3 is the cut-away view of the utility model second piston element.
This embodiment of tool
The first chamber primary cup 7, the second chamber primary cup 3, the first chamber secontary cup 8, the second chamber secontary cup 4 are captiveed joint with the leather cup groove of Master cylinder body 1; First spring members 6 is arranged on the first piston parts 9; Second spring members 2 is arranged on second piston element 5; First piston parts 9, second piston element 5 are connected in the Master cylinder body 1, and 16 apertures are respectively arranged above.
One, two chamber flows of master cylinder are by the quantity and the decision of valve port size of fuel feed hole on the piston; Wherein the size of the valve port in first chamber is realized by 16 apertures on the first piston parts 9 and the first chamber primary cup, 7 rigging positions, and the size of the valve port in second chamber is by 16 apertures on second piston element 5 and the realization of the second chamber primary cup, 3 rigging positions.First and second spring members adopts the mode of riveted joint spring position-limited lever to fix.16 radially oil throughs are arranged on first and second piston element, can increase or reduce radially oil through quantity according to the cylinder diameter size.
