ABSTRACT:
A vehicle washing machine is disclosed, of a type particularly adapted for washing relatively large vehicles, such as buses, vans, trucks, etc. featuring a mounting arrangement for a pair of side brushes which are disposed in the wash lane so as to scrub the sides of the washed vehicles. The mounting of each swing frame arrangement includes a swing frame on which each brush is rotatably mounted, inclined to the horizontal, and pivotally mounted to the frame so as to be able to pivot into engagement with the vehicle side. Each swing frame is urged into engagement with a vehicle passing between the side brushes by a shock absorber-spring assembly acting on the upper end of the swing frame urging the brush into the wash lane, while accommodating minor in and out movements due to variations in the vehicle contour, side motions, etc., the shock absorber damping the resulting oscillations of the swing frame. The adjustable width arrangement is provided by an air cylinder-cable combination connecting both swing frames and adapted to draw the swing frames together upon sensing the presence of a narrow width vehicle by operation of the air cylinder to adapt the machine to the narrow width vehicle. The resulting driving connection between the swing frames allows simultaneous swinging movement of the swing frames due to accommodate a limited off-centering position of the vehicle in the wash lane while maintaining the width between the brushes. Each swing frame is also disclosed as carrying a motor-gear unit combination utilized to rotate each side brush while the vehicle is passing between the side brushes, and is also disclosed as being adjustably mounted to the machine frame to provide an adjustable skew angle between the brushes.
