The invention discloses a front auxiliary engine integrated structure of a new energy commercial vehicle, which comprises a main driving motor, an air compressor, a steering oil pump and a front end gear structure, and is characterized in that the main driving motor drives the air compressor and the steering oil pump through the front end gear structure, and the air compressor and the steering oil pump are coaxially arranged; the front end gear structure comprises a first transmission gear and a second transmission gear which are connected in a meshed mode, 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 connectors are reserved in the connecting positions of the front end of the main driving motor, the air compressor and the steering oil pump. The main driving motor can be used for driving the air compressor and the steering oil pump at the same time, when high voltage is reduced due to faults of an electrical system during running of a vehicle, wheels can be used for driving a rear axle and a transmission shaft to reversely drag the driving motor, driving force is provided for the steering oil pump, the steering function of the vehicle is kept, the electrical system of the whole vehicle is simplified, arrangement space is optimized, and safety is improved.
本发明公开了一种新能源商用车的前置辅机集成结构,包括主驱动电机、空气压缩机、转向油泵和前端齿轮结构,主驱动电机通过前端齿轮结构驱动空气压缩机和转向油泵,空气压缩机和转向油泵同轴布置,前端齿轮结构包括第一传动齿轮和第二传动齿轮,第一传动齿轮和第二传动齿轮相互啮合连接,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,主驱动电机的前端与空气压缩机和转向油泵连接处预留有接口,可利用主驱动电机同时驱动空气压缩机、转向油泵,车辆行驶中因电气系统故障导致掉高压时,可利用车轮带动后桥、传动轴反拖驱动电机,为转向油泵提供驱动力,使车辆保持转向功能,进而简化整车电气系统,优化布置空间、提升安全性。
