ABSTRACT:
A wrap brush assembly includes an elongated, horizontal upper support arm which pivots from an overhead support about a vertical axis. A pivot link is pivotally connected to the free end of the upper support arm about a horizontal pivot link axis for movement forward and rearward relative to the path traversed by a vehicle to be cleaned. A brush support bracket is pivotally connected to the lower end of the pivot link about an axis lying perpendicular to the pivot link axis for allowing the brush support bracket to swing side to side relative to the path traversed by a vehicle to be cleaned. A motor, brush shaft, and wrap brush are supported from the brush support bracket. A shock absorber dampens forward/rearward movement about the horizontal pivot link axis, and a stop limits inward pivoting movement of the brush support bracket relative to the pivot link to prevent the wrap brush from climbing onto the rear deck of the vehicle. The overhead support includes a horizontal support beam bridging the path traversed by the vehicle to be cleaned; the vertical axis about which the upper support arm pivots is displaced away from the horizontal support beam, and such vertical axis and the brush extend on opposite sides of the horizontal support beam.
