Abstract
The utility model discloses a braking master pump assembly comprising a cylinder body, wherein a left piston and a right piston are arranged in a working cavity of the cylinder body in a sliding fit way, the inner sides of the left piston and the right piston are respectively connected with a leather cup, the inner sides of the leather cups are provided with opposite spring seats, a spring is cushioned between the spring seats, and the side wall of the cylinder body is provided with an oil inlet and an air outlet. In the braking master pump assembly disclosed by the utility model, the processing process of the pistons is simple, the performance is good, the strength is high, clearances between every two parts in the working cavity of the cylinder body are easy to match, and the sealing property is good. Meanwhile, the production cost is low, and the service life is long.
Description
Technical field:
The utility model relates generally to a kind of automobile brake field, relates in particular to a kind of master brake cylinder assembly.
Technical background:
Hydraulic braking master cylinder adopts braking liquid as working medium, utilize the incompressibility of liquid to produce braking and drive force, make the brake component action, reach the purpose of automobile brake, general master brake cylinder is realized by piston motion, and piston is wanted additional central control cock structure and locating dowel pin under normal reciprocating situation, therefore piston structure design, complex manufacturing, become to produce cost higher, and the overall performance of piston is low, intensity is also lower, simultaneously because the part in the master cylinder body running chamber increases, and the cumulative errors between each part are difficult to control, often cause in the cylinder body epitrochoidal chamber gap between each part too big or cooperation is too tight, thereby cause overall performance to descend, can not satisfy practical requirement.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of master brake cylinder assembly is provided, solved piston processing technology complexity, performance is low, intensity is low, the gap in the cylinder body epitrochoidal chamber between each part is not easy to cooperate problems such as poor sealing.
The utility model is achieved through the following technical solutions:
A kind of master brake cylinder assembly includes cylinder body, is sliding combined with left and right piston in the epitrochoidal chamber of described cylinder body, the inboard of left and right piston is connected with leather cup respectively, the inboard of leather cup is provided with relative spring perch, is equipped with spring between the spring perch, and the sidewall of cylinder body has oil inlet, air extractor duct.
The two ends, the left and right sides of described cylinder body are separately installed with guard shield.
The utility model has the advantages that:
The utility model adopts leather cup to match with inboard wall of cylinder block, and the piston processing technology is simple, performance good, intensity is high, and the gap in the cylinder body epitrochoidal chamber between each part cooperates easily, good airproof performance, and productive costs is low simultaneously, long service life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model left view.
The specific embodiment:
Referring to accompanying drawing, a kind of master brake cylinder assembly, include cylinder body 1, be sliding combined with left and right piston 2,3 in the epitrochoidal chamber of cylinder body 1, the inboard of left and right piston is connected with leather cup 4 respectively, and the inboard of leather cup 4 is provided with relative spring perch 5, is equipped with spring 6 between the spring perch, the sidewall of cylinder body has oil inlet 7, air extractor duct 8, and the two ends, the left and right sides of cylinder body are separately installed with guard shield 9.
