Abstract
A steering and drive system for toy vehicles is disclosed. Independent gear trains for wheels on opposite sides of the toy vehicle are utilized in combination with a single reversible motor to either rotate all wheels in the same direction to move the vehicle in a straight line or, by reversing the direction of the motor, to rotate wheels on opposite sides of the vehicle in opposite directions causing the vehicle to turn. Wheels on one side of the vehicle are connected to a main gear and the direction of rotation of such wheels is completely dependent upon the polarity of an electric power source applied to the motor. Wheels on the opposite side of the vehicle are indirectly connected to the main gear by a movable control gear which is urged to engage either an auxiliary gear or a second side drive gear so that the wheels rotate in only a single direction regardless of the direction of the motor.
