ABSTRACT:
A bumper car amusement ride includes a floor to which is adhesively bonded over their entire under surfaces a plurality of elongated electrically conductive plates separated by electrically non-conductive strips and with adjacent plates connected across a source of alternating current. A bumper car is supported for movement over the plates and strips by a pair of laterally spaced drive wheels and a pair of longitudinally spaced caster wheels, each of the drive wheels being coupled to the reversible, variable speed output of a hydrostatic transmission, the inputs of which are both coupled to the output of a direct current constant speed electric motor. The motor is connected through a rectifier to a plurality of contacts mounted on the car for sliding engagement with the floor plates.
