Abstract

The vehicle washing installation comprises at least one conveyor chain (1) in the form of a sprocket chain, by means of which the vehicles are moved through the installation, and a plurality of treatment units arranged along the path of movement of the vehicle for washing and optionally drying the vehicle. At least one of the treatment units is mounted in a carrier adapted to move forwards synchronously with the vehicle over a path length and to be moved back by means of a resetting device to its starting position. The carrier can be coupled mechanically to the conveyor chain (1) for the forward movement. The coupling device comprises a coupling member (8) which can be brought into direct engagement with the conveyor chain (1). The coupling member (8) is of comb-like form and comprises a plurality of teeth (8a) spaced in the longitudinal direction (L) of the chain at a distance (b) from one another, with gaps (8b) therebetween. The pitch (t1) of the gaps (8b) is an integral fraction of the pitch (t) of the chain studs (10). The gap width (b) in the longitudinal direction (L) of the chain is somewhat greater than the diameter (d) of the chain studs (10).
