Problems solved by technology

However, the core technologies of the above valves are in the hands of foreign manufacturers and they are expensive. Domestic products of the same type have a certain gap with foreign products in terms of function and performance. As a result, the current mature solutions are heavily dependent on foreign manufacturers. To a certain extent It hinders the widespread popularization of EBS on domestic dangerous goods semi-trailer trucks

Abstract

The invention relates to the field of automobile brake systems, and discloses an air pressure EBS of a dangerous goods semi-trailer transport vehicle. The air pressure EBS comprises an EBS ECU, an automatic pressure regulating valve, a pressure differential meter, a front brake air chamber, an electric control brake master valve, a double-cavity brake air chamber, a wear sensor, a rotating speed sensor, a steering tire pressure sensor and an emergency cut-off valve control pipeline pressure sensor. The brake air chamber is sequentially connected with the automatic pressure regulating valve, the electric control brake main valve and an air tank through pneumatic pipelines, and the pressure differential meter is installed on the brake air chamber. A semi-trailer braking hand brake is independently and additionally arranged and used for controlling the braking force of the semi-trailer under the condition that EBS electronic control fails; aiming at the national requirements of the dangerous goods semi-trailer transport vehicle, the tire burst emergency safety device and the emergency cut-off valve are incorporated into the EBS monitoring range, and the air pressure EBS has importantsignificance for the safety improvement of the dangerous goods semi-trailer transport vehicle.

Description

technical field [0001] The invention relates to the field of automobile brake systems, in particular to an air pressure EBS of a dangerous goods semi-trailer transport vehicle. Background technique [0002] At present, the air pressure electronic parking system (EBS) of the domestic dangerous goods semi-trailer is mainly composed of an electronically controlled brake master valve, an air storage tank, an air pressure control valve (ABS valve and proportional relay valve, and a bridge containing the functions of the above two valves. Valves, etc.), trailer valves, emergency relay valves, pneumatic brake lines and brake chambers, EBS ECU, various sensors (force sensors, brake friction wear sensors, coupling force sensors, etc.) and electronic control circuits and other components composition. By actuating the brake main valve pedal, the driver transmits pedal travel and pedal force signals to EBSECU to identify the driver's braking intention; ECU integrates the real-time data...
