Abstract

See full text

A toy vehicle for use in a toy vehicle game including an endless track defining at least two parallelly extending vehicle lanes in which two or more toy vehicles are adapted to be operated. The toy vehicles each include a reversible rotary drive motor and a transmission operatively engaged between the motor and two drive wheels for simultaneously driving the drive wheels in the forward direction, while selectively driving them at different speeds, in response to the direction of rotation of the drive motor, thereby to control the turning radius of the vehicle when changing lanes and biasing the vehicle against one or the other of the side walls of the track to guide the vehicle along its path of travel in one or the other of the lanes.
