Patent ID: 7935193

Claim:
A method of washing wheels of a vehicle, which comprises the steps of: providing a wheel washing assembly containing: a pendulum assembly pivotably supported on a machine frame and freely swinging about a pivot point; and two washing manifolds, including a first washing manifold and a second washing manifold, attached to the pendulum assembly, each of the washing manifolds having a nozzle assembly for ejecting water at the wheel to be washed, the first washing manifold having a roller assembly; moving the vehicle through the wheel washing assembly with one of the wheels engaging and pushing the roller assembly, beginning at a start position, causing an automatic tracking of two of the wheels by the first and second washing manifolds, respectively; ejecting water at the two wheels being tracked by the first and second washing manifolds; driving over the roller assembly at an end position; and subsequently pivoting the first and second washing manifolds back to the start position via the pendulum assembly.
