Problems solved by technology

[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 may not be easy to climb in some steep places, causing inconvenience for people using wheelchairs, and need someone to help

Abstract

The invention relates to a wheel hub structure provided with a reduction box. The wheel hub structure comprises a wheel hub; a motor is arranged at the axle center of the wheel hub; a brake device is arranged on one side of the motor; the reduction box is arranged between a motor shaft and a wheel hub. The reduction box comprises a gear shaft connected to the motor shaft; a sun gear is arranged on the gear shaft; the sun gear is engaged with a planetary gear in the reduction box; a driving pinion is arranged at the axle center of the planetary gear; and the driving pinion is engaged with a large gear ring. By employing the structure mentioned above, the output speed is reduced, the safety is guaranteed as a wheelchair cannot move too fast, and the forward torque of the wheelchair is increased.

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 may not be easy to climb in some steep places, causing inconvenience to people using wheelchairs, and someone needs help. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a hub structure with a reduction box: [0004] Including the hub, the axis of the hub is provided with a motor, one side of the motor is provided with a brake device, and a reduction box is provided bet...
