Integrated-type air braking system for new energy commercial vehicle

Abstract

The invention relates to an integrated-type air braking system for anew energy commercial vehicle. The integrated-type air braking system comprises an ECU, an electronic control braking master valve (11), two plunger-type spring braking air chambers (8), a hand relay valve (13), and an ABS regulator relay valve integration module (7). The ECU is connected with the electronic control braking mastervalve(11). The ECU and the electronic control braking master valve(11) are correspondingly connected with the ABS regulator and relay valve integration module(7). The ABS regulator and relay valve integration module (7) is correspondingly connected with braking cavities of the two plunger-type spring braking chambers (8). The hand relay valve (13) is connected with parking cavities of the two plunger-type spring braking chambers (8). Compared with the prior art, the integrated-type air braking system for the new energy commercial vehicle has the beneficial effects that, integrated design is correspondingly carried out on an existing quick release valve and an ABS regulator, and an existing relay valve and an ABS regulator; the number of system pipeline components and pipeline connecting joints is further decreased, the overall weight of the system is decreased by 20%, installation space of the system can be reserved, and therefore overall arrangement, installation and maintenance areconvenient to carry out.

Description

technical field [0001] The invention relates to a commercial vehicle air brake system, in particular to an integrated air brake system for new energy commercial vehicles. Background technique [0002] With the increasing shortage of oil resources, urban environmental pollution is becoming more and more serious. Since 2013, all parts of the country have been attacked by smog. In order to increase the emission reduction and noise reduction of urban buses, it is urgent to develop green and clean energy as the The representative pure electric bus, and the air brake system for new energy commercial vehicles is the key system of pure electric buses, and its performance is directly related to the operation performance of the whole vehicle. At present, the electronically controlled air handling system of the air brake system for commercial vehicles is an air supply and treatment system specially for pure electric or hybrid vehicles. The existing air brake systems for pure electric v...

Problems solved by technology

However, on the one hand, the invention does not install an inverter between the electric drive air compressor and the air dryer, so the flexible and fast start-up and variable-speed operation of the motor cannot be realized; on the other hand, the overall system has many pipeline components, resulting in The road connection joints also increase correspondingly, which is inconvenient for installation and maintenance
