Quick dismounting type hub motor

Abstract

The invention discloses a quick dismounting type hub motor. The motor includes a motor hub, a motor shaft, a stator unit, a terminal fixing rack, a terminal socket, a transition cover, an end cover, apush rod and a quick dismounting knob. The terminal fixing rack is fixed on the motor shaft and is disposed between the stator unit and the transition cover. The terminal socket is arranged on the terminal fixing rack and penetrates through the transition cover. The transition cover is fixed on the motor shaft and is connected with the end cover via a bearing piece. The push rod is mounted in anaxle hole in an external connection end of the motor shaft. The side wall of the push rod is provided with an annular slope-shaped groove equipped with steel balls. The motor shaft is provided with alimit hole having a diameter smaller than that of the steel balls. The end part of the push rod is provided with a step. A step lock net and the push rod step are fixedly arranged in the motor axle hole in a corresponding manner. The quick dismounting knob is fixed at the outer end of a connection rod of the push rod. According to the invention, the terminal socket and a terminal on a vehicle arein direction plug connection and no cable is exposed, so that cost is saved and simplicity and practicability are achieved; line system is optimized by adopting an inner wire outlet mode; and dismounting and carrying are facilitated and individual weight after dismounting is reduced since no screws and nuts are required for installation on the vehicle.

Description

technical field [0001] The invention relates to a quick-detachable wheel hub motor, which belongs to the fields of motors and electric vehicles. Background technique [0002] The external power supply and electrical signal connection of the existing electric wheelchair motor all lead out a multi-core cable from the motor, and then connect the multi-core aviation plug / waterproof plug to connect with the external control system and power supply system. It is not conducive to cable fixing, high cost, cumbersome assembly, and affects appearance. [0003] At the same time, in order to facilitate portability and storage, many customers require that the whole vehicle can be disassembled, and hope that after the disassembly of the whole vehicle, the monomer is light in weight and small in size. The existing structural assembly of the motor and the frame is fixed with screws and nuts. , It is not conducive to the folding / disassembly of the whole vehicle, and the weight of the split ...

[0002] The external power supply and electrical signal connection of the existing electric wheelchair motor all lead out a multi-core cable from the motor, and then connect the multi-core aviation plug / waterproof plug to connect with the external control system and power supply system. It is not conducive to cable fixing, high cost, cumbersome assembly, and affects appearance

[0003] At the same time, in order to facilitate portability and storage, many customers require that the whole vehicle can be disassembled, and hope that after the disassembly of the whole vehicle, the monomer is light in weight and small in size. The existing structural assembly of the motor and the frame is fixed with screws and nuts. , which is not conducive to the folding / splitting of the whole vehicle, and the weight of the split unit is relatively large
