<p>The electric drive uses a DC motor (2) incorporated as a hub motor in the running wheel of the wheelchair. The motor has an external rotor (8) which acts as the wheel hub or rim of the running wheel, with the stator (9) secured to the wheelchair via a brake housing (3) of an electromagnetically and manually operated air brake (4), acting on the rotor upon current failure. Pref. the dished brake housing is attached to the stator on the opposite side of the motor to the external rotor and encloses a brake disc (37) with a spring-loaded pressure plate (38). The brake disc cooperates with a coupling pin (35) of the wheel hub shaft (11) of the external rotor, projecting into the brake housing.</p> |
