Abstract

The invention relates to an integrated auxiliary system for a pure electric commercial vehicle. The auxiliary system comprises a driving motor 1, a driving motor controller 2, a support 3, a transmission system, an air compressor 8, a steering system, an air conditioner compressor 5, a low-voltage generator 6, a cooling water pump and a cooling lubricating system. The air conditioner compressor 5 is located on the right side of the reduction gearbox 4, the low-voltage generator 6 is installed on the upper portion of the reduction gearbox 4 in a screwed mode, the main belt pulley 413 is simultaneously connected with a driven belt pulley of the air conditioner compressor 5 and a driven belt pulley of the low-voltage generator 6 through a belt 11, and the steering oil pump 7 is connected to the right rear side of the reduction gearbox 4 in a screwed mode. The output shaft of the drive motor 1 is fixedly connected with the input shaft of the steering oil pump 7. The air compressor gear 420 is meshed with a second gear 407 in the reduction gearbox 4, the driving motor controller 2 is located on the rear portion of the steering oil pump 7, and the air compressor 8 is located on the left rear side of the reduction gearbox 4. The system is high in integration level, compact in structure, reasonable in performance and arrangement, simple to control, low in cost and light in weight.

Description

technical field [0001] The invention belongs to the technical field of pure electric vehicles, and in particular relates to an integrated auxiliary system for pure electric commercial vehicles. Background technique [0002] At this stage, pure electric commercial vehicles are strongly supported and promoted by the society and the state, and the market demand is gradually increasing.
