Abstract: 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.

Abstract: A magnetic coupling, includes a driving rotor sleeved on the driving shaft, a driven rotor sleeved on the driven shaft, external magnets mounted on the driving rotor and internal magnets mounted on the driven rotor and located on the inner sides of the external magnets; a plurality of internal magnets are arranged and uniformly distributed along the circumferential direction of the driven rotor; the external magnets and the internal magnets are aligned one by one along a radial direction; the internal magnets and the external magnets are magnetized along the radial direction; adjacent internal magnets have opposite magnetizing directions, and adjacent external magnets have opposite magnetizing directions; magnetic poles of the internal magnets are opposite to magnetic poles of the corresponding external magnets, and the driving rotor and the driven rotor form a working magnetic circuit through a magnetic field generated by the external magnets and a magnetic field generated by the internal magnets, wherein at
