Claim 13:
14. 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; and
first and second torque receiving members (62, 64) mounted within the first and second hubs respectively, wherein the first and second torque receiving members are shaped to engage with the first and second drive axles respectively,
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,
and wherein the first and second torque receiving members are integrally formed within the first and second hubs respectively.
