REMOTE CONTROL TOY VEHICLE WITH IMPROVED STABILITY

摘要

A remote control toy motorcycle (10) includes a steering link (46) and a four-bar linkage (48) to connect a front castering wheel (28) to a chassis (20), to utilize the castering wheel principle and the counter steering principle in a manner which enhances the stability of the motorcycle (10), thereby enabling it to be operated on rugged terrain. A steering drive (44) responds to radio signals to cause the link (46) to pivot the four-bar linkage (48) to initiate and maintain a turn. The four-bar linkage (48) has spaced members (58a, 58b) located on opposite sides of the longitudinal axis, with rearward ends pivotally connected to the chassis (20) at locations further from the longitudinal axis than forward ends which pivotally connect to a front wheel fork coupler (60). The four-bar linkage (48) enables pivotal movement of the front wheel (28) about a castering arc (68) which is projected in front of the four-bar linkage (48). The toy vehicle (10) further includes a flywheel assembly (110) incorporated within the rear wheel (30), to further enhance stability. A propulsion drive (80) drives the rear wheel (30) and a weighted flywheel (114), with the weighted flywheel (114) rotating substantially faster than the rear wheel (30) during operation.
