The invention provides a miniature commercial vehicle power steering system which comprises a vehicle frame, a steering machine, a power steering oil pot, a power steering oil pump arranged on one side of the vehicle frame, a radiator arranged in the middle of the vehicle frame and the power steering oil pot arranged on the radiator, and an oil outlet of the power steering oil pot is communicated with an oil inlet of the power steering oil pump through a first pipeline arranged along the radiator. An oil outlet of the power steering oil pump is communicated with an oil inlet of the steering engine through a second pipeline, and an oil outlet of the steering engine is communicated with an oil return opening of the power steering oil can through a third pipeline. According to the design, the power steering oil can is integrally installed on the radiator, on one hand, the first pipeline is arranged along the radiator, the length of the first pipeline is greatly reduced, on the other hand, the problems of abnormal power-rotating sound and heavy steering of a rotating system at low temperature are solved, and the NVH performance of the vehicle is improved.

    一种微型商用车动力转向系统,包括车架、转向机、动转油壶、设置在车架一侧的动转油泵、设置在车架中部的散热器、设置在散热器上的动转油壶,动转油壶的出油口通过沿散热器布置的一号管路与动转油泵的进油口连通,动转油泵的出油口通过二号管路与转向机的进油口连通,转向机的出油口通过三号管路与动转油壶的回油口连通。本设计通过将动转油壶集成安装在散热器上,一方面,使一号管路沿散热器布置,大大减少了一号管路的长度,另一方面,解决了转动系统在低温时存在动转异响、转向沉重的问题,提高了车辆的NVH性能。
