Synchronous air brake system controlled by electric current

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...

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.
