Abstract
The utility model relates to a new braking proportional valve which belongs to the technical field of vehicle braking. A joint is riveted with a valve body. A sealing circle is arranged between the joint and the valve body. A piston is movably connected with the joint. An O-shaped circle 1 is arranged between the piston and the joint. A gasket and a main spring are sleeved at the outside of the piston. An O-shaped circle 2 is arranged between the piston and the valve body. The valve body is annularly riveted with a retainer ring. A piston holder is movably connected with the valve body. A backspring is sleeved at the piston holder which is provided with a steel ball. A mandril is arranged in the piston and is movably connected with the piston. One end of the mandril is contacted and connected with the steel ball. The utility model has the advantages that: the structure is novel, the space occupation of the proportional valve is minished, cost of the braking proportional valve is reduced and service life of products is increased.
Description
Technical field
The utility model belongs to the automobile brake technical field, especially to the improvement of automobile brake apportioning valve.
Background technology
Brake power proportioning system is the critical component in the brake system of car, be installed between the master brake cylinder and trailing wheel wheel cylinder of brake system of car, automobile is in braking procedure, automatically regulate the brake-pressure of trailing wheel by a certain percentage, avoid automobile in braking procedure whipping and trailing wheel early than the front-wheel locking, thereby give full play to brake efficiency, improve reliability and the safety of automobile in braking procedure.
The brake power proportioning system in early stage, as shown in Figure 4.Mainly contain valve body 1, piston 2, Rubber Parts valve 3, main spring 4, spring perch 5, seal ring 6, positioning seat 7, O type circle 8, back-up ring 9, adjusting pad 10 is formed, and the shortcoming of this kind brake power proportioning system is: valve is a Rubber Parts, and valve is fragile during long-term work.The structure of brake power proportioning system connects simultaneously needs to fix separately with car body, and input cavity all needs other to connect by fuel filler pipe with output cavity, and the shared volume of brake power proportioning system is also bigger.Material requested is also many, the cost height.
Summary of the invention
The utility model provides a kind of later-model brake power proportioning system, to solve the problem that existing fragile, the shared volume of apportioning valve valve is big, material is many, cost is high.The technical scheme that the utility model is taked is: joint 1 and valve body 2 riveted joints, seal ring 4 is arranged between this joint and valve body, piston 6 is connected with joint sliding, O type circle 1 is arranged between piston 6 and joint, packing ring 5, main spring 7 are socketed in the piston outside, O type circle 2 10 is positioned between piston and valve body, valve body 2 and back-up ring 9 annular riveted joints, piston seat 12 and valve body sliding block joint, retracing spring 13 is socketed on the piston seat, steel ball 11 is positioned on this piston seat, and push rod 8 is positioned at piston and is connected with the steel ball contact with its sliding block joint and an end.
Principle of work of the present utility model is: brake power proportioning system also is the difference footpath formula piston structure that adopts the two ends bearing area not wait, in the confined state process, piston 6 is under the effect of main spring 7 predetermincd tensions, be in opening between piston 6 and the steel ball 11, when the braking beginning, hydraulic pressure is entered in the valve body by input cavity, outputs to the back brake wheel cylinder.Because hydraulic pressure does not also overcome the application force of spring, this moment, input cavity pressure equaled output cavity pressure, increase along with input hydraulic pressure, when hydraulic action meets and exceeds the initial tension of spring of setting, piston begins to move right, piston 6 is in contact with one another with steel ball 11, valve port is closed, this moment, input cavity and output cavity were completely cut off, and piston is in state of equilibrium, when continuing to increase as if input hydraulic pressure, the hydraulic action that acts on the piston input end increases thereupon, when greater than the application force on the mouth piston, state of equilibrium is broken, and piston is moved to the left, throw off between piston 6 and the steel ball 11, valve port is opened, and finishes a working cycle process, plays the process that output hydraulic pressure reduces in proportion.
The utility model has the advantages that: novel structure, at first simplify connecting of brake power proportioning system and brake system, the input cavity of apportioning valve directly is associated on the master brake cylinder.Next has reduced the shared volume of apportioning valve, reduces the cost of brake power proportioning system.Change the seal form of input cavity and output cavity simultaneously, adopted steel ball to replace the seal form of rubber valve, increased product service life.
