The invention relates to an electric wheel which comprises a rim, a wheel carrier, a damping mechanism, a motor and a parallel eccentric coupler. The wheel carrier is rotationally arranged on the inner ring of the rim. The damping mechanism is arranged on the wheel carrier. The motor is arranged on the damping mechanism, and the damping mechanism allows the motor to generate displacement within aset range in the vertical direction of the use state. The parallel eccentric coupler is arranged between the output end of the motor and the rim, the eccentric distance of the parallel eccentric coupler is variable within a set range, and the parallel eccentric coupler can be eccentric in the vertical direction of the use state. The invention further provides an automobile chassis comprising the electric wheel and a new energy automobile. According to the electric wheel, the automobile chassis and the new energy automobile, the vertical vibration of the motor and the transmission of the driving torque are decoupled through the synergistic effect of the damping mechanism and the parallel eccentric coupler, so that the air gap change of the stator and the rotor in the motor is reduced, the impact load of a road surface on the motor is relieved, and the service life of the motor is prolonged.

    本发明涉及一种电动车轮,包括轮辋、轮架、减振机构、电机和平行偏心联轴器。轮架转动设置于轮辋的内圈。减振机构设置于轮架。电机设置于减振机构,减振机构允许电机沿使用状态的竖直方向产生设定范围内的位移。平行偏心联轴器设置于电机的输出端和轮辋之间,平行偏心联轴器的偏心距在设定范围内可变,平行偏心联轴器能够沿使用状态的竖直方向发生偏心。本发明还提供包括上述电动车轮的汽车底盘以及新能源汽车。上述电动车轮、汽车底盘及新能源汽车中,减振机构和平行偏心联轴器协同作用将电机的垂向振动和驱动力矩的传递解耦,减小电机中定子和转子的气隙变化,缓解了路面对电机的冲击载荷,有利于延长电机的寿命。
