Description
Technical field
The device in commercial car light truck braking system is the utility model is related to, is joined in particular to a kind of axial seal
The preceding bridge control module connect.
Background technology
Anti-lock braking system ABS, full name are Anti-lock Brake System, be it is a kind of have prevent wheel from embracing
Extremely, the vehicle safety control system for the advantages that shortening automobile brake distance, reducing tire wear, prevent Vehicle Driving Wandering, whipping, it
Worked based on conventional braking system.In the case where wheel is close to locking, corresponding wheel brake pressure will be released and
It is required that or measure wheel acceleration period kept constant again, be stepped up brake pressure after accelerating again.Equivalent to every
A wheel is individually " point is stopped ".
In recent years, domestic automobile industry is constantly in high speed development state, and light truck also gradually starts to match ABS systems.
The front brake circuit of light truck air pressure at present is in assembling ABS solenoid valves（Two）, quick release valve etc. when, three or two stents need to be used
Three above component is independently mounted on vehicle frame respectively, is connected wherein between quick release valve and solenoid valve with cotton thread pipe or other pipelines
Connect, such a assembling form can cause frame cross hole position to increase, and the route of pipe line between valve intersects in a jumble, slow down the response of system
Time, reduce vehicle intricacies, overall volume is larger, weight penalty, and installation difficulty increases.
Such as Authorization Notice No. is 203032668 U Chinese utility model patents of CN, it discloses a kind of ABS solenoid valves
With the sectional shelf-unit of quick release valve, including the rack body for being fixed on vehicle frame, the lower end of the frame body is to its both sides
Each extension one is used for the second support of Motionless electromagnetic valve；Preferably, the mounting plane of the second support is higher than rack body
Mounting plane；Preferably, the second support is equipped with the kidney slot for Motionless electromagnetic valve.The combination of the utility model
Stent, by quick release valve be installed on rack body on, two solenoid valves are separately positioned in two second supports, and with connector by its
Connect, so three components can be only assemblied together by connector, then sectional shelf-unit is secured on vehicle frame again.
This sectional shelf-unit instead of three original independent racks, not only save two cotton thread pipes, two perforation connectors, two perforation
Bolt, but also improve the exquisite technique of vehicle.But both sides solenoid valve electrical apparatus interface direction is opposite inwardly, when quick release valve is pacified
It will be interfered, and can make troubles the installation to plug wire Shu Duan of solenoid valve when filling muffler.
In another example Authorization Notice No. is the Chinese utility model patent of 204775206 U of CN, it discloses a kind of ABS gas
Pressure control system, includes gas receiver, brake valve, ABS solenoid valves, quick release valve, preceding brake chamber, wheel speed sensors, servo
Pneumatic line between valve, rear brake chamber and above-mentioned each component；Wheel speed sensors coordinate with wheel；Quick release valve passes through pneumatic tube
Road connects the first ABS solenoid valves and the 2nd ABS solenoid valves respectively；Brake valve is connected by the 3rd ABS solenoid valves with relay valve；
Preceding brake chamber is two, is engaged respectively with two front-wheels；Brake chamber is two afterwards, is engaged respectively with two trailing wheels.
The technical program, by the way that former four ABS solenoid valves are improved to three ABS solenoid valves, solve vehicle and is separated in attachment systems
Road surface on when braking, because the brake force on same axis is unequal, and produces larger deflection torque and produce brake side-slipping and ask
Topic.But quick release valve is then to connect the first ABS solenoid valves and the 2nd ABS solenoid valves respectively by pneumatic line, makes whole product
Weight penalty, space increase, response time are slow.
Again for example shown in Fig. 4, pile-up valve of the prior art will entirely be collected by increasing installing plate 31 on quick release valve seat 3
It is fixed on into valve on vehicle, adds installing plate 31 and add the weight of pile-up valve entirety, while manufactures cost raising.
