Abstract
A remote control toy motorcycle includes a steering link and a four-bar linkage to connect a front castering wheel to a chassis, to utilize the castering wheel principle and the counter steering principle in a manner which enhances the stability of the motorcycle, thereby enabling it to be operated on rugged terrain. A steering drive responds to radio signals to cause the link to pivot the four-bar linkage to initiate and maintain a turn. The four-bar linkage has spaced members located on opposite sides of the longitudinal axis, with rearward ends pivotally connected to the chassis at locations further from the longitudinal axis than forward ends which pivotally connect to the front wheel fork coupler. The structure enables pivotal movement of the front wheel about a castering arc which is projected in front of the four-bar linkage. The toy vehicle further includes a weighted flywheel assembly incorporated within the rear wheel, to further enhance stability. A propulsion drive drives the rear wheel and the flywheel, with the gyroscopic flywheel rotating substantially faster than the rear wheel during operation.
