Problems solved by technology

However, this document does not involve how to ensure that the front and rear brake pressures are consistent
Moreover, this document does not describe how the pressure sensor establishes the relationship between the input air pressure and the output current signal, so it cannot fundamentally guide the realization of synchronous braking of the front and rear wheels of the car.

Embodiment Construction

[0022] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Fig. 1 is a schematic diagram of the structure of the present invention. As shown in FIG. 1 , the current control synchronous coordinated air pressure braking system of the present invention is composed of a front braking unit 2 , a current control unit 3 and a rear braking unit 4 connected in sequence. The front brake unit 2 includes a front air storage tank 21 , a brake valve 22 and a front brake chamber 23 connected in sequence. When the car driver stepped on the brake valve 22, the compressed air of the front air storage tank 21 communicated with the air compressor 5 entered the brake chamber 23 through the brake valve 22, and the front brake push rod moved to push the adjusting arm to brake. The rear brake unit 4 includes a rear air storage tank 41 , a relay valve 42 and a rear brake chamber 43 connected in sequence. The relay va...

Abstract

This invention relates to an electric control synchronous coordinate air-pressure brake system, which provides a new air-pressure brake technology project controlled by electric signal. When the front wheel brakes, the front gas reservoir compresses air and enters the front brake air cushion through the brake valve, the first electric pressure transformer turns the pressure that output by the brake valve into the electric signal, and the single flake intelligent control deals with the back pressure electric valve to output the pressure signal that controls the open of the relay valve, the compressed air in back gas reservoir enters the back braking air chamber to achieve the back wheel braking. The output end of the pressure electric valve has the second electric pressure transformer, which turns the output pressure into the electric signal, and sends the signal back to the control to form the closed-loop control circuit, which makes the front braking air chamber consistent to the back braking air chamber. Because the telecommunication transmission seldom delays, so this invention achieves the real synchronous coordinate braking.

Description

technical field [0001] The invention relates to pneumatic braking, in particular to a long-distance pneumatic braking system controlled synchronously and harmoniously by microcurrent. Background technique [0002] Large and medium-sized cars, trains, urban light rail vehicles, etc. generally use air pressure braking, but such as semi-trailer, full-trailer, etc., when braking, front and rear collisions, bouncing, sideslip, flicking, folding and even rolling often occur between the tractor and the trailer. , causing traffic accidents. The reason is that the front and rear brakes are not synchronized and uncoordinated. Existing air pressure braking is that the driver steps on the brake pedal to open the brake valve, and the brake valve outputs gas with different pressures in proportion to the pedal strength, and the gas reaches the front wheel and the rear wheel respectively through the air pipe. The gas directly enters the air chamber of the front wheel to push the connectin...
