    • A wheel hub assembly comprising a rim, an outer cap and an inner body joined to the cap within the rim and carrying automatically extendable and retractable curved traction elements. The traction elements are curved pieces with inner end portions disposed on the inside of the tire when retracted and outer ends substantially concealed in gaps between the rim and the cap when retracted, and extendable into active positions overlying the tread of the tire by electric motors each driving two rack-and-pinion drives through T-drives between two traction elements. Channel-shaped tracks and guide rollers on the hub base support the traction elements, which have traction-enhancing ribs and studs on their outer end portions. An alternative embodiment has a hollow annular hub body on which the traction elements are mounted and guided, in two circular slots, with the motors inside the annular body, the body being supported on a framework to be bolted to the central hub element of a conventional wheel.
    • 一种轮毂组件,其包括轮辋,外盖和内轮毂,所述内轮毂在所述轮辋内连接到所述盖并承载自动伸缩的弯曲牵引元件。 牵引元件是弯曲件,当缩回时,内端部设置在轮胎内侧,外端部在缩回时基本上隐藏在边缘和盖子之间的间隙中,并且可通过电动机每个可延伸到覆盖轮胎胎面的有效位置 通过两个牵引元件之间的T型驱动驱动两个齿条齿轮传动。 轮毂基座上的通道形轨道和引导辊支撑牵引元件,牵引元件在其外端部分上具有牵引力增强肋和螺栓​​。 一个替代实施例具有中空的环形轮毂体,牵引元件在该中空环形轮毂体上以两个圆形的槽形式安装和引导,其中马达在环形体的内部,该主体被支撑在框架上,以被固定到中心轮毂元件上, 轮。
