Muscle-powered wheeled vehicle

摘要

The invalid chair has at least one manually driven drive wheel (1) in which an external rotor electric motor (11,12,14) is integrated, for providing a torque which assists the rotation of the drive wheel. The stator (11) of the electric motor is supported by the wheel mounting (4) for the drive wheel. The external rotor is supported via ball bearings from the wheel mounting and the motor control (9) and the electric battery for the motor are contained within an annular space (4a) concentric to the wheel hub (4a).
