Electric wheelchair drive system |
摘要 |
Motorized wheels in a wheelchair or other light vehicle are each mounted on an axle for limited rotation relative to a secondary connection to the frame of the vehicle which incorporates a sensor providing feedback which controls the motor according to torque sensed through the secondary connection. The motor and associated gearing and control circuitry are housed within a wheel hub of which a drum supporting a wheel rim is supported at its inner surface on multiple bearings spaced around its periphery.
