Abstract
A rotating brush assembly is disclosed for a vehicle washing apparatus. The brush assembly includes a brush and a flexible plastic brush shaft which permit the brush to swing or tilt in response to the force exerted on the brush by the movement of the vehicle relative to the vehicle washing apparatus. The brush motor rotates the brush in a direction which walks the brush along the surfaces of the vehicle. The combined action of the rotary reaction force of the brush against the vehicle and the flex of the flexible plastic brush shaft causes the brush to turn the front and rear corners of the vehicle to wash the front, side and rear surfaces. In addition, a brush assembly pivot mechanism is installed on the brush assembly to permit the brush to pivot in a direction parallel to the path of the vehicle in the event the vehicle is inadvertently driven into the brush while the brush is not rotating. The brush assembly pivot mechanism prevents damage to the vehicle and the brush assembly.
