Embodiment Construction

[0012] Such as figure 1 and figure 2 A hub structure with a reduction box is shown, including a hub 1, a motor 4 is provided at the axis of the hub 1, a braking device 3 is provided on one side of the motor 4, and a brake device 3 is provided between the motor shaft 5 and the hub 1. There is a reduction box 2; the reduction box 2 includes a gear shaft 2-3 connected with the motor shaft 5, and a sun gear 2-2 is arranged on the gear shaft 2-3, and the sun gear 2-2 is evenly connected with the reduction box 2. Two distributed planetary gears 2-4 are meshed, and a drive pinion 2-5 is arranged on the axis of the planetary gear 2-4, and the lower part of the drive pinion 2-5 is a pin shaft, which is fixedly inserted into the At the axis of the planetary gear 2-4, the drive pinion 2-5 meshes with the large ring gear 2-1.

[0013] The above planetary gears 2-4 are not limited to two, as long as there are more than two, it can be realized, and the uniform distribution can ensure tha...

Abstract

The invention relates to a hub structure provided with a reduction box. The hub structure comprises a hub, wherein a motor is arranged at the axis position of the hub, a braking device is arranged on one side of the motor, the reduction box is arranged between a motor shaft and the hub and comprises a gear shaft which is connected with the motor shaft, a sun gear is arranged on the gear shaft and is meshed with a planetary gear arranged in the reduction box, a small driving gear is arranged at the axis position of the planetary gear, and the small driving gear is meshed with a large gear ring. After the structure is adopted, the output speed is lowered, safety problem of a wheelchair caused by an overhigh speed can be solved, forward torque of the wheelchair is enlarged, and the wheelchair is made to be suitable for being used in advancing on a road provided with a slope.

Description

technical field [0001] The invention relates to a wheel hub structure used by a wheel, in particular to a wheel hub structure with a reduction box. Background technique [0002] At present, in some wheelchair manufacturers, when manufacturing self-propelled wheelchairs, the motor is usually used to drive the wheels forward, and the motor shaft is directly connected to the hub, so that the speed of the wheelchair is easy to be too fast due to the high speed of the motor. It is easy to cause danger, and its torque is not large. It is possible that it is not easy to climb in some steep places, causing inconvenience for people using wheelchairs, and it is inconvenient for disabled people to go out. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wheel hub structure with a reduction box that can increase the torque and reduce the speed of the wheelchair. [0004] The technical solution adopted by the present invent...
