Abstract
A conveyor roller assembly typically for pushing a vehicle through a car wash having a chain drive and split track, includes a bar extending form its forward end beneath the track to its back end above it. The back end carries a pair of rollers that travel on the track and a second pair of rollers for pushing against the tire of the vehicle. The front end carries an axle rigidly attached to the bar and a pair links one on each side of the bar and each link rigidly carrying a sleeve having a very close tolerance with the axle and through which the axle extends. The links attach to the chain drive, and rollers are carried by the sleeves and engage the lower surface of the track. The link, sleeve and roller arrangement causes the conveyor roller assembly to maintain alignment with the track.
