Variable-speed hub motor

Abstract

The invention belongs to the technical field of wheels and provides a variable-speed hub motor which solves the problems that an original supporting shaft is provided with a guiding groove, an adjusting rod hole and a power line hole, and therefore the strength of the supporting shaft is lowered, the supporting shaft is prone to deformation and breakage, driving safety is affected, and heat of a motor wrapped by a hub ring can not be dissipated effectively. The variable-speed hub motor comprises a hub ring which is connected with an end face, the end face is connected with a hollow output shaft, a motor body is fixed on a supporting shaft, a power line of the motor body directly stretches out of a motor shell, and the motor body and a gearbox body are exposed out of the end face. The variable-speed hub motor is characterized in that the supporting shaft and a motor shaft are parallel, a driven gear is provided with inner teeth, the hollow output shaft is provided with a pawl moving groove, a pawl shaft penetrates through a pawl arranged in the pawl moving groove, the pawl can tilt in the pawl moving groove, and the pawl moving groove is provided with a pressure spring enabling one end of the pawl to tilt and to be clamped on the inner teeth.

Description

technical field [0001] The invention belongs to the technical field of wheels. Background technique [0002] A motor and a gearbox body are wrapped in the usual speed-changing hub ring, and the motor is fixed with a hollow support shaft stretching out from the two end faces of the hub ring. The hollow support shaft of the wheel hub of this structure increases the difficulty of processing and greatly weakens the rigidity and strength of the support shaft due to the adjustment rod hole, guide groove and power cord hole. cause a threat to driving safety. In addition, because the motor is wrapped by the hub ring, the heat emitted by the motor during operation cannot be effectively dissipated, and the motor and components are easily burned due to overheating. Contents of the invention [0003] In order to solve the above-mentioned deficiencies, the object of the present invention is to provide a support shaft with high rigidity and strength, which is not easy to be twisted, d...
