Abstract
A toy car adapted to travel on a track assembly is disclosed. The toy car includes a motor coupled to a drive train which drives the car forwards regardless of a direction of rotation of an output shaft of the motor. The drive train includes a first set of gears coupled with a first one-way clutch to drive an axle of the car when the output shaft of the motor rotates in a first direction. The drive train also includes a second set of gears coupled with a second one-way clutch to drive the axle when the output shaft rotates in a second direction. The first set of gears represent a higher gear reduction ratio from the output shaft to the axle than the second set of gears whereby a speed of the forward motion of the car may be altered by reversing the direction of rotation of the motor. The motor of the car draws electric power from the track assembly. A suitable switch and an electric circuitry are operatively associated with the track assembly to reverse polarity of direct current supplied to the track whereby the direction of rotation of the motor is reversed.
