ABSTRACT:
A wash oscillator for use in providing high impact wash and rinse action on a lateral surface of a vehicle in an automatic wash facility. The wash oscillator comprises a support structure positioned on a support surface of the wash facility and a motor, having a rotatable output shaft, fixedly attached to the support structure. The oscillator further comprises a spray bar having a plurality of spray nozzles for providing perpendicular impact of washing and rinsing agents onto a lateral surface of the vehicle. The spray bar is pivotally mounted to the support structure via attachment to a pivot block which pivots about an axis of a hinge pin which is rotatably supported by pillow blocks mounted on a support structure. A linkage mechanism connects the output shaft of the motor with the pivot block so as to convert rotary motion of the shaft into an oscillating pivoting motion of the spray bar about the hinge pin axis. The linkage mechanism includes a spring linkage arm having a spring element which is always loaded in compression and which damps the oscillating pivoting motion of the spray bar so as to reduce shock loads imparted at the upstroke and downstroke positions of the spray bar, thereby enhancing the fatigue life of the bearings included in the pivotal mounting mechanism.
