摘要 |
Apparatus which enables a foldable wheelchair to be retrofitted with an electrical propulsion system without significantly compromising the ability to fold the chair. The apparatus includes a drive unit for each wheel to be driven. The drive units can be mounted on the stationary axles of the driven wheels and apply torque, generated by a separate motor in each drive unit, to the wheels at a plurality of symmetrically located points which are radially displaced from the axles.
