ABSTRACT:
A control system for a dual-wheel drive which includes two drive motors independently controllable by regulating the amount of current which flows to each of the motors. Two contact means are provided wherein one is a rotatable wiper arm system and the other is a pivotable plate system. A control motor continuously moves one of these two contacts while a drive wheel selectively moves the other contact. One of the contacts serves as a common electrical supply terminal for both of the drive motors while the other contact has separate terminals respectively coupled to each of the two drive motors to supply them with current. The contact relationships between the two contacts are selectively controlled by means of the drive wheel whereby the amount of current directed to flow in each of the two motors is controlled.
