The invention belongs to the field of vehicle engineering, and relates to a reinforced heat dissipation type hub motor trailing arm suspension, which comprises a trailing arm, a hub motor, a brake, aheat dissipation water inlet pipe, a heat dissipation water outlet pipe, a brake hydraulic pipeline, a fastening bolt, a trailing arm mounting attached seat, a spring connecting pin, a cable and a rotary transformer sensor, the longitudinal arm pin shaft end is coupled with the longitudinal arm mounting auxiliary seat to form a rotating pair; the hub motor is installed on the longitudinal arm connector through a fixing bolt. The longitudinal arm is of a thin-wall structure, an inner cavity of the longitudinal arm is divided into an upper pipeline, a middle pipeline and a lower pipeline which are independent, wherein two of the pipelines are a heat dissipation water inlet channel and a heat dissipation water outlet channel, and the rest one allows a cable to pass through. The heat dissipation pipe is connected with the heat dissipation water inlet channel and the heat dissipation water outlet channel; and the cable passes through the middle pipeline. A hub motor, a brake, a cable and apipeline are integrated through a hollow thin-wall trailing arm structure, trailing arm type modular integration of a form driving system is achieved, so that through component modular design, energyconsumption is reduced through interchangeability, the manufacturing cost is low, and maintenance is easy.
