Problems solved by technology

Therefore, often when the brake pedal sensor fails or a transmission failure occurs during the transmission of a separate electrical signal or air pressure signal, the brake system cannot effectively control the pressure change of the brake line to perform vehicle braking. so prone to dangerous accidents

Abstract

The invention relates to a main brake valve with electronic control and pneumatic control, which is characterized in that dual-circuit electronic control and dual-circuit pneumatic control are generated respectively by electrical signals and pneumatic signals which are obtained through detecting a brake intent, thereby controlling the rise and drop of brake pressure of a brake system, wherein twocontrol circuits independently exist in the main brake valve, when one of the control circuits malfunctions, the other control circuit keeps running; and when one circuit in the dual-circuit control malfunctions, the other circuit still takes effect. By using the main brake valve provided by the invention, braking operations implemented by drivers become safer and more reliable.

Description

technical field [0001] The invention relates to a brake master valve with both electric control and gas control, and is especially applied to an electronically controlled braking system (referred to as an EBS system) and a braking system of a new energy vehicle. The invention belongs to the technical field of automobile braking system control. Background technique [0002] Air pressure-controlled dynamic braking systems are widely used in commercial vehicles such as trucks and buses. Usually, air compressors and high-pressure gas storage cylinders are used to supply air. The driver operates the brake master valve to control the air pressure in the brake pipeline. Air is sent to the pistons in the wheel braking system, which causes the air brakes to generate the corresponding braking force. The main brake valve of the car is an important structure in the braking system. When the car brakes, the air pressure delivered to each brake cavity through the main brake valve, the for...
