TOY VEHICLE WITH PIVOTALLY MOUNTED SIDE WHEELS

摘要

A radio-controlled toy vehicle (10) is provided with four non-steerable wheels (30), two on each lateral side (24, 26) of the vehicle. The wheels (30) on each lateral side are drivingly coupled with a separate reversible motor (44, 46). The vehicle is steered by controlling the operation and direction of each motor. Pivoting beam (27) is centrally located on one lateral side with the wheels (32, 34) on that side being rotatably attached to the beam. The pivoting beam (27) provides for infinite ranges of suspension positions. The vehicle proceeds until it encounters an obstacle and depending upon the size of the obstacle relative to the size of the wheels (30), the vehicle either rolls over the obstacle or climbs up the obstacle and flips over. Two beams (20, 200) may be provided, each supporting a pair of front and rear wheels on separate lateral side of the vehicle.
