Abstract
Provided is a powered wheelchair having the drive motors mounted to the driven wheels. The wheelchair includes a seat and first and second side frames extending in a parallel relationship to support opposite sides of the seat. First and second driven wheels are rotatably mounted on the first and second side frames through a fixed axle shaft. First and second drive motors are fixedly mounted on the first and second driven wheels, respectively, and are operatively connected by first and second drives to the first and second driven wheels, respectively. Rotation of the first and second drive motors causes rotation of the driven wheels. Control of the motors is provided by a remote control arrangement, the transmitter mounted to one of the side frames and the receiver mounted on the rotatably mounted wheels.
