Abstract

The invention relates to an air brake system for a new energy commercial vehicle. The air brake system comprises an ECU (Electrically-controlled Unit), a motor-driven air compressor (1) and an electrically-controlled air drier (2), wherein the ECU is connected with the electrically-controlled air drier (2); the motor-driven air compressor (1) is connected with the electrically-controlled air drier(2); an inverter (13) is arranged between the motor-driven air compressor (1) and the electrically-controlled air drier (2); the ECU is connected with the inverter (13). Compared with the prior art,the air brake system has the beneficial effect that the inverter is arranged between the motor-driven air compressor and the electrically-controlled air drier, so that flexible rapid startup and various-speed running of a motor are realized. Conventional diesel engine oil is taken as lubricating oil of the motor-driven air compressor, so that the adverse consequence of failure of the brake systemcaused by fatal damage to rubber sealing parts due to the adoption of special lubricating oil in the existing electric air compressor is avoided.

Description

technical field [0001] The invention relates to an air braking system for a commercial vehicle, in particular to an air braking system for a new energy commercial vehicle. 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 ...
