ABSTRACT:
An automotive vehicle washing system includes a frame comprising a bridge member end opposed and support sections mounted for linear reciprocating movement on spaced apart support rails. Pivoting washing nozzle support arms are mounted on the bridge section and are interconnected by a drive motor and drive pulleys to move in opposite directions to wash the sides and opposite ends of a vehicle. Each arm includes movable arm sections supporting spaced apart nozzle assemblies which may move toward each other or away from each other to size a vehicle according to its width. Each arm includes opposed elongated beam members which also provide fluid conducting passages for conducting washing fluids to the nozzle assemblies. Certain ones of the nozzle assemblies are drivenly connected to an oscillating servomotor. The servomotor is also used to position the pivoting arm sections through a lost motion coupling and a gear drive unit.
