摘要： A coupling for axle-suspended installation of a direct drive motor, comprises a wheel axle side adapting flange coaxially fixed with a wheel axle and a motor side adapting flange coaxially fixed with the rotor shaft of a motor, an elastic support rotating assembly, wherein the elastic support rotating assembly is radially connected between the wheel axle side adapting flange and the motor side adapting flange so that the wheel axle side adapting flange and the motor side adapting flange can be coaxially and rotatably connected and bear the weight of the motor along the radial direction through the elastic support rotating assembly, and the wheel axle side adapting flange and the motor side adapting flange are circumferentially elastically connected. It also provides stiffness design method of coupling for axle-suspended installation of direct drive motor.
