Abstract
An accumulation system for driverless vehicles of the type which are propelled along a track by contact between the drive wheel and a rotating drive shaft. Accumulation being caused by contact between a swing arm extended from the front end of a driverless vehicle. The swing arm pivots towards the front end of the driverless vehicle causing a corresponding rotation of the drive wheel with respect to the rotating drive shaft. The change in position of the drive wheels with respect to the axis of the drive shaft causes a deceleration of the driverless vehicle and/or accumulation of the vehicle with respect to the adjacent driverless vehicle on the track.
