The invention discloses a disc-type wheel hub motor integrated with a shock absorber. The motor comprises a stator structure, a rotor structure, a central shaft and a shock absorber; the central shaftis vertically arranged in the stator structure and the rotor structure in a penetrating manner; the rotor structure is rotationally connected with the central shaft; the outer edge of the rotor structure is fixedly connected with a tire; the shock absorber is fixedly arranged on the inner side of the stator structure; the stator structure is fixedly connected with the center shaft through the shock absorber; the stator structure is used for being fixed to a vehicle body; the stator structure is located outside a tire; the stator structure and the rotor structure are oppositely arranged in parallel; and the stator structure can generate an axial magnetic field parallel to the center shaft when powered on. According to the invention, the stator structure and the rotor structure are arrangedin a planar mode, so that the arrangement flexibility is improved; the unsprung mass is reduced; the operation stability and smoothness are improved; the shock absorber is integrated, so that the rotor structure has the vertical degree of freedom, meanwhile, vertical automatic reset can be achieved; and the problems of shaft abrasion and energy loss caused by extra shaft constraints are avoided.
