    • A radio-controlled toy vehicle is provided with four non-steerable wheels, two on each lateral side of the vehicle. In one embodiment, the wheels on each lateral side are drivingly coupled with a separate, reversible motor. The vehicle is steered by controlling the operation and direction of each motor. In another embodiment, the wheels on each lateral side are drivingly coupled with a single reversible motor. The vehicle is steered through one-way clutches which allow the wheels on one lateral side to operate in either a forward or a reverse direction while the wheels on an opposite lateral side always rotate in the same direction. In both embodiments, a pivoting beam is centrally located on one lateral side, with the wheels on that side being rotatably attached to the beam. The pivoting beam provides for infinite ranges of suspension positions. In operation, the vehicle proceeds until it encounters an obstacle. Depending upon the size of the obstacle relative to the size of the vehicle wheels, the vehicle either rolls over the obstacle or climbs up the obstacle and flips over. In yet another embodiment, two beams are provided, each supporting a pair of front and rear wheels on separate lateral sides of the vehicle.
    • 无线电控制的玩具车辆设置有四个不可操纵的车轮,两个在车辆的每个侧面。 在一个实施例中,每个侧面上的轮子与单独的可逆电动机驱动耦合。 通过控制每个电机的操作和方向来控制车辆。 在另一个实施例中,每个侧面上的车轮与单个可逆电动机驱动耦合。 车辆通过单向离合器转向,其允许一个侧面上的车轮在前进方向或反向方向上操作,而相对侧面上的车轮总是沿相同方向旋转。 在两个实施例中,枢转梁位于一个侧面的中心,其侧面上的轮可旋转地附接到梁上。 枢转梁提供无限范围的悬挂位置。 在操作中,车辆进行直到遇到障碍物。 根据障碍物相对于车轮尺寸的大小,车辆或者在障碍物上滚动或爬上障碍物并翻转。 在另一个实施例中,设置有两个梁,每个支撑在车辆的分开的横向侧上的一对前轮和后轮。
