Claim 21:
22. A wheelchair propulsion system (10) comprising:
first and second rotatable hubs (26, 28) for mounting to first and second wheels (14a, 14b) of a wheelchair (16) respectively;
an elongated axle tube (12) arranged between the first and second hubs;
first and second motors (22, 24) arranged within the axle tube extending from opposing ends thereof (18, 20);
first and second drive axles (38, 40) extendable through entire lengths of bores (34, 36) of the first and second rotatable hubs respectively, the first and second drive axles releasably operatively connecting the respective first and second motors to the respective first and second rotatable hubs, wherein the first and second drive axles are operatively connected to the first and second motors by first (42) and second (44) couplers, the first coupler arranged to connect the first drive axle to the first motor and the second coupler arranged to connect the second drive axle to the second motor; and
means (103) for moving the first and second couplers in a longitudinal axis of the axle tube, between positions to engage with and disengage from the first and second drive axles,
wherein actuation of the first and second motors transfers a torque to the first and second drive axles and to the first and second hubs, thereby rotating the first and second wheels respectively,
and wherein the first and second drive axles each comprises a releasable mechanism configured to move the drive axle between an engagement position for engagement of the first and second drive axles with the respective first and second motors and the respective first and second hubs and a disengagement position for disengagement of the first and second drive axles from the respective first and second motors and the respective first and second hubs.
