Units 4 are connected；Braking gas receiver 5 passes sequentially through the second controlled pneumatic regulating valve 6, the second quick release valve 7 and back axle braking and holds afterwards
Units 8 are connected, the first controlled pneumatic regulating valve 2 and the second controlled pneumatic regulating valve 6 respectively with signal of telecommunication brake pedal 9 phase
Even.Specifically, that is, the gas outlet of front braking gas receiver 1 is connected with the first controlled pneumatic regulating valve 2, and the first controlled pneumatic is adjusted
The gas outlet of valve 2 is connected with the first quick release valve 3, and the gas outlet of the first quick release valve 3 is connected with propons braking executive component, front braking
Gas receiver 1, the first controlled pneumatic regulating valve 2, the first quick release valve 3 are braked with propons and are connected by air pipe between executive component 4；
Afterwards braking gas receiver 5 gas outlet be connected with the second controlled pneumatic regulating valve 6, the gas outlet of the second controlled pneumatic regulating valve 6 and
Second quick release valve 7 is connected, and the gas outlet of the second quick release valve 7 is braked executive component 8 with back axle and is connected, and brakes gas receiver 5, second afterwards
Controlled pneumatic regulating valve 6, the second quick release valve 7 are braked with back axle and are connected by air pipe between executive component 8；Meanwhile, the signal of telecommunication
It is connected by the signal of telecommunication respectively between brake pedal 9 and the first controlled pneumatic regulating valve 2 and the second controlled pneumatic regulating valve 6, electricity
By driver's control, driver, according to braking needs, pushes pedals, makes pedal revolve certain angle, exports phase signal brake pedal 9
The signal of telecommunication answering degree is to the first controlled pneumatic regulating valve 2 and the second controlled pneumatic regulating valve 6, the first controlled pneumatic regulating valve 2
And second controlled pneumatic regulating valve 6 receive the signal of telecommunication after, export correspondingly sized air pressure to the first quick release valve 3 and the second quick release valve
7, compressed air be divided into after the first quick release valve 3 two or more gas circuits to and propons braking executive component 4, compressed air is through the
It is divided into two or more gas circuits to brake executive component 8 to back axle after two quick release valves 7.
Preferably, signal of telecommunication brake pedal 9 can export one or more groups of signals of telecommunication as needed, and gas circuit is unified
Or control respectively.This utility model is preferably two groups of signals of telecommunication, and two groups of signals of telecommunication control the braking execution of propons and back axle respectively
Element；This control device, also dependent on needs, carries out customization and the adjustment of waveform, to reach to the multigroup electric control signal exporting
To each braking braking sequential of executive component, severity of braking joint control it is adaptable to the vehicle of difference use demand.
Further, signal of telecommunication brake pedal 9 is directly to step on formula pedal.
Further, the first controlled pneumatic regulating valve 2 and the second controlled pneumatic regulating valve 6 are normally off.Namely when
During normal vehicle operation, signal of telecommunication brake pedal 9 not output signal, the first controlled pneumatic regulating valve 2 and the second controlled pneumatic tune
Section valve 6 is normally off, is supplied with the source of the gas cutting off brakes, braking pressure is zero, and brake force is zero.
Operation principle of the present utility model is as follows:
1) normal vehicle operation state: the signal of telecommunication control pedal 9 not output signal under this state, the first controlled pneumatic is adjusted
Section valve 2 and the second controlled pneumatic regulating valve 6 are in normally off, the source of the gas supply of cut-out brakes, and braking pressure is zero, system
Power is zero；
2) when vehicle needs braking: under this state, driver is by trampling signal of telecommunication brake pedal 9, the required system of input
Fatigue resistance, the signal of telecommunication (can be curtage signal) of now signal of telecommunication brake pedal 9 output respective strengths, first is automatically controlled
After air pressure regulator 2 and the second controlled pneumatic regulating valve 6 receive signal, open corresponding gas circuit, and the power according to input signal
Adjust the correspondingly sized air pressure of output, air pressure is divided into two by the first quick release valve and/or the second quick release valve, exports to propons system
Dynamic executive component and/or back axle braking member, produce required brake force；Propons brake circuit and the braking of back axle brake circuit
Corresponding time and big I being actually needed according to car load of brake force, by the change of signal of telecommunication brake pedal 9 curve of output
To adjust；
3) when braking needs to release: under this state, driver unclamps signal of telecommunication brake pedal 9, and signal of telecommunication brake pedal 9 is defeated
Go out signal vanishing, meanwhile, the first controlled pneumatic regulating valve 2 and the second controlled pneumatic regulating valve 6 receive signal, cut-out source of the gas
Circulation, and delivery outlet is connected with air vent, the first controlled pneumatic regulating valve 2 and the second controlled pneumatic regulating valve 6 are to propons system
Air in pipeline between dynamic executive component and back axle braking member, by the first controlled pneumatic regulating valve 2 and the second automatically controlled gas
The air vent of pressure regulating valve 6 and the first quick release valve and the second quick release valve is discharged, and propons braking executive component and back axle braking execute
Element recovers zero brake force position.
The beneficial effects of the utility model are: 1) by using signal of telecommunication brake pedal, can cancel under anterior driver's compartment
The air pipe in portion；2) signal of telecommunication brake pedal, directly can install in the car, overhaul, easy to operate；3) whole system is only very short
Gas circuit connect source of the gas, controlled pneumatic regulating valve and brake actuator, the consumption of tolerance can reduce；4) by the air pressure of distance
Conduction control is changed to signal of telecommunication control, makes forward and backward bridge braking executive component response time short, the linear loss very little of gas circuit.
Embodiment described above is only preferred implementation of the present utility model to be described, not to this practicality
New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of this utility model claims determination
