ABSTRACT:
A portal frame of a vehicle-washing station, carrying cylindrical brushes for scrubbing the body of a vehicle moving relatively to that frame, supports a pair of oppositely disposed wheel-cleaning units with respective rotary brushes confronting the sides of the vehicle at the level of its wheels. Each wheel-cleaning unit comprises a feeler, normally retracted, which at the beginning of a traverse is extended into the path of the proximal wheel pair to sense the arrival of the leading wheel in a scrubbing position. The feeler then causes the arrest of the main drive and the advancement of the associated wheel-scrubbing brush into contact with the vehicle wheel so positioned; the same happens with the wheel-cleaning unit at the opposite side. During this operation the feeler is again retracted; when relative motion of the vehicle and the portal frame resumes, the feeler is again extended to repeat the aforedescribed procedure with the trailing vehicle wheel.
