The invention discloses a rear auxiliary engine integrated structure of a new energy commercial vehicle, which comprises a main driving motor, an air compressor, a steering oil pump, a transmission and a front end gear structure, and is characterized in that the main driving motor drives the front end gear structure by driving an input shaft of the transmission, and drives the air compressor and the steering oil pump through the front end gear structure; the front end gear structure comprises a first transmission gear and a second transmission gear, the steering oil pump and the air compressor are connected to the two sides of a rotating shaft of the second transmission gear respectively, and a connector is reserved in the position, connected with the air compressor and the steering oil pump, of the front end of the transmission. The main driving motor is used for simultaneously driving the air compressor and the steering oil pump, even if high pressure drops during running of the vehicle, the wheels can be used for driving the rear axle and the transmission shaft to reversely drag the transmission, driving force is provided for the steering oil pump, the steering function of the vehicle is kept, an electrical system can be simplified, and safety is improved.
本发明公开了一种新能源商用车的后置辅机集成结构,包括主驱动电机、空气压缩机、转向油泵、变速器和前端齿轮结构,主驱动电机通过带动变速器的输入轴驱动其前端齿轮结构,通过前端齿轮结构驱动空气压缩机和转向油泵,前端齿轮结构包含有第一传动齿轮和第二传动齿轮,转向油泵和空气压缩机分别连接在第二传动齿轮旋转轴的两侧,变速器的前端与空气压缩机和转向油泵连接处预留有接口,本发明通过将空气压缩机、转向油泵集成在变速器前端,利用主驱动电机同时驱动空气压缩机、转向油泵,车辆行驶中即使掉高压,也可利用车轮带动后桥、传动轴反拖变速器,为转向油泵提供驱动力,使车辆保持转向功能,同时可简化电气系统,提升安全性。
