Elevated track vehicle with drive wheel and two auxiliary wheels

摘要

The elevated track vehicle has a drive wheel (3) running on a profiled tack (1). Two horizontally spaced auxiliary wheels (8) increase the drive wheel pressure on the track. The auxiliary wheels run both against the drive wheel and against a parallel auxiliary track (7). Each of the two auxiliary wheels is connected by an L-jointed lever pair (9,10) to the vehicle frame (5). A spring (16) and or damping element acts between the two levers of each lever pair. The two auxiliary wheels are connected to each other pref. by rigid connecting rod (913).
