    • A roadway having a smooth road surface for automotive vehicles includes means for transmitting electric current through the road surface to electrically-operated vehicles travelling thereon. Each electrified traffic lane is provided with at least two spaced parallel electrical contact assemblies mounted with their top surfaces flush with the road surface and in position to be contacted one with a wheel on each side of the vehicle, with the contact assemblies each requiring a predetermined weight thereon to maintain electrical contact with the vehicle wheels. The vehicle employs electrically-conductive tires which roll on the electrically-conductive surface of the contact assemblies, and the current thus picked up is transmitted, through rolling-sliding contacts, conductors, etc. to controls for controlling the operation of the vehicle through individual wheel motors. The vehicle motors may be electric, but preferably are hydraulic or pneumatic motors which are driven as pumps or compressors during deceleration to thereby conserve energy, with the electric current driving a suitable pump or compressor to supply motive fluid through suitable pressure storage reservoir to the wheel motors during acceleration and normal driving. A battery pack is included for supplying current to operate the vehicle when the wheels are not on the contact assemblies, which battery pack is charged from current picked up from the roadway during normal operation or from special re-charging pads while the vehicle is parked.
    • 具有用于机动车辆的平滑路面的道路包括用于将电流通过路面传递到在其上行驶的电动车辆的装置。 每个电气化的行车道设置有至少两个间隔开的平行的电接触组件,其安装有它们的顶表面与路面平齐并且与车辆每一侧上的车轮接触的位置,其中接触组件需要预定的 以保持与车轮的电接触。 车辆采用导电轮胎,其滚动在接触组件的导电表面上,并且如此拾取的电流通过滚动滑动触点,导体等传输到控制器,以控制车辆通过个体的操作 轮电机。 车辆电动机可以是电动的,但是优选地是液压或气动马达,其在减速期间作为泵或压缩机被驱动,从而节省能量,电流驱动合适的泵或压缩机以通过合适的压力存储容器向轮子供应动力流体 电机在加速和正常驾驶期间。 当车轮不在接触组件上时,包括用于提供电流以操作车辆的电池组,该电池组在正常操作期间从当前从道路拾取的电流充电,或者在车辆停放时由特殊的再充电垫充电。
