[0002] The majority of the logistics sorting machines on the market currently use ordinary three-phase reduction motor, asynchronous linear motor, synchronous linear motor, etc. With the continuous development of logistics equipment, the number of cells required by small logistics sorting machines is also increasing, making the sorting machine become longer and longer. If a three-phase reduction motor is used, a single large motor will be used in general chain transmission to adapt to the long-distance conveying system, which will increase the tension of the system transmission chain and enhance the strength of the chain, resulting in increased cost. Asynchronous linear motor and synchronous linear motor have the problems of low electromechanical conversion rate and high energy consumption. SUMMARY

[0006] In one preferred embodiment of the utility model, each hub motor assembly is installed on a swing bracket, one end of which is hinged to the power frame, and a compression spring mechanism is provided between the other end of the swing bracket and the power frame. The compression spring mechanism applies an external force to the swing bracket, so that the friction drive wheels in the hub motor on the swing bracket are clamped together on the secondary plate of the walking trolley of the sorting machine.

[0007] In one preferred embodiment of the utility model, each hub motor assembly includes an electric drive and a friction drive wheel arranged around the electric drive. The electric drive drives the friction drive wheel to rotate through a planetary gear reducer.

[0008] In one preferred embodiment of the utility model, a layer of polyurethane material is coated around the outer periphery of the friction drive wheel to increase wear resistance and friction performance.
