ABS combination relay valve specific embodiment is as follows: ABS combination relay valve includes valve chest, it is placed in the switch assembly 10 of valve chest inner chamber bottom, stepless voltage transformation device 50 with switch assembly 10 movable contact, the voltage stabilization and regulation device 70 being connected with stepless voltage transformation device 50, is communicated in the input air pressure configuration pressure regulation responding device 60-2 of stepless voltage transformation device 50, voltage stabilization and regulation device 70 simultaneously.In the present embodiment, switch assembly 10, stepless voltage transformation device 50, the housing of voltage stabilization and regulation device 70 are structure as a whole, and so make the more compact structure of relay valve.
Wherein, valve chest is made up of lower house 1, upper shell 4, upper cover 6.
Switch assembly 10 is the control switch of gas receiver and arrester, and its operation principle is: when master cylinder opens valve 1-5 by stepless voltage transformation device, and the air pressure of gas receiver just can be directly entered arrester.
The valve 1-5 of the direct contact switch assembly 10 of main valve stem 5 in stepless voltage transformation device 50；Switch assembly 10 is controlled by main valve stem 5；When main valve stem 5 moves down, when making valve 1-5 open, the air pressure from trailer gas receiver is directly entered arrester through primary inlet port 1-10 and is braked；Voltage stabilization and regulation device 70 is connected between the second work chamber 5-7 and the 5th work chamber 5-10, regulates and controls the air pressure in stepless voltage transformation device 50.
This ABS combines relay valve, owing to being provided with stepless voltage transformation device 50 and voltage stabilization and regulation device 70 on mechanical realization, when not combining with ABS, still can prevent that the braking effect dragging tire mode is to keep the controllability of vehicle with frame for movement.
Stepless voltage transformation device 50, in the present embodiment, upper diaphragm assembly 5-3 is compressed on being spirally connected on face of upper cover 6 and upper shell 4, lower diaphragm assembly 5-1 is compressed on being spirally connected on face of upper shell 4 and lower house 1, two the first work chamber 5-6 being not attached to lead to, the second work chamber 5-7 is formed respectively in the both sides up and down of upper diaphragm assembly 5-3；The both sides up and down of lower diaphragm assembly 5-1 form the 4th work chamber 5-9, the 5th work chamber 5-10 respectively；Logical master cylinder outside first work chamber 5-6.
Utilize housing compacting diaphragm formation to be not attached to the structure of the work chamber led to each other, can preferably ensure that the air pressure of each chamber does not leaks.
In order to realize stepless voltage transformation function, communicating passage is set between the first work chamber 5-6 and the 4th work chamber 5-9.This utility model is directly provided with through hole in the shaft core position of main valve stem 5 corresponding to two chambers, and this communicating passage can also be arranged on housing, or is realized by external pipeline after holing in housing relevant position.But latter two mode is easily caused the leakage of chamber pressure, and meanwhile, processing technique is relative complex.
In order to reach the sealed against one another of each work chamber, in the position that main valve stem 5 contacts with housing, sealing ring can be set, make main valve stem 5 when relative housing moves up and down, it is ensured that the sealing of each chamber.
In order to describe operation principle more easily, in this utility model, definition diaphragm assembly upper chamber is malleation chamber, and diaphragm lower chamber is vacuum chamber.
Voltage stabilization and regulation device 70 includes: adjust screw 7-1, pressure maintaining valve upper chamber 7-3, voltage stabilizing piston 7-4, voltage stabilizing module 7-5, voltage stabilizing upper channel 7-6, controlling valve 7-7, contiguous block 7-8, voltage stabilizing lower channel 7-9.Wherein, voltage stabilizing upper channel 7-6 and the second work chamber 5-7 is connected, and voltage stabilizing lower channel 7-9 and the 5th work chamber 5-10 is connected；Pressure maintaining valve upper chamber 7-3 is connected with passage 7-2 after lower valve.
Be described below ABS combination relay valve operation principle:
In braking procedure, the wheel speed sensors of ABS configuration sends the drop-out value of wheel speed to ECU, the Q-value of the curve values of wheel speed suppression ratio in the unit interval with an inner setting is compared by ECU, if this curve values is more than Q-value, show that wheel speed declines abnormal, i.e. it is considered as in car braking producing " locking " phenomenon, now ECU output signal drives normally closed solenoid valve 6-16 to open and simultaneously close off relief hole 6-17, first work chamber 5-6, air pressure one tunnel in 4th work chamber 5-9 is through valve prepass 6-13, after valve, passage 6-15 acts on configuration valve film 6-14, active force makes valve rod 6-12 move to right, close or reduce the air inflow of air inlet valve 6-11, thus reduce the first work chamber 5-6, pressure in 4th work chamber 5-9；Meanwhile, air pressure in first work chamber 5-6, the 4th work chamber 5-9 passage 7-2 after valve prepass 6-13, valve acts on pressure maintaining valve upper chamber 7-3, active force changes voltage stabilizing value makes voltage stabilizing piston 7-4 move down, and the air pressure in vacuum chamber 5-10 simultaneously acts on vacuum chamber 5-7 through voltage stabilizing lower channel 7-9, controlling valve 7-7, voltage stabilizing upper channel 7-6.Reducing and the increase of vacuum chamber's pressure of above malleation chamber pressure, makes the valve 1-5 in switch assembly close immediately or air inflow reduces, and reduces overall braking action amount, to release " locking " state.
