Abstract: An endless track structure to replace the wheels of an all-terrain vehicle, that is adequately attached to the existing wheel hub by a removable mounting shaft. This provides a non-rigid frame that supports spaced apart synchronized driving cog wheels. This frame has mounted within its upper portion, two hexagon bore anti-friction bearings that slide onto a hexagon shaped thin wall sleeve, allowing the assembled track structure to be installed as a unit. There are spaced idler wheels in front and rear portions of the non rigid frame that support the track. They form a triangular configuration with raised front portion and flat rear portion. A non rigid frame provides interconnected resilient leaf spring supports located in the front and rear of the track.An endless track maintains its appropriate configuration over the driving cog wheels by the front and rear idler wheels, and under the lower course by spaced apart slider rub bars supported by a flexible frame. An optional intermediate suspension may be substituted for the slider with a pair of spaced apart front and rear intermediate idler wheels at the frame portion.The ability to adjust the position of the front and rear idler wheels in relation to the bearing support is accomplished by multiple mounting holes in the front and rear leaf spring. This allows the track to be lengthened to the front or rear, and still use the same length endless track.

Abstract translation: 用于替换全地形车辆的车轮的循环轨道结构，其通过可移除的安装轴适当地附接到现有的轮毂。 这提供了一个支撑间隔开的同步驱动齿轮的非刚性框架。 该框架已经安装在其上部内部，两个内六角孔的抗摩擦轴承滑动到六边形薄壁套筒上，允许组装的轨道结构作为一个单元安装。 在非刚性框架的前部和后部中有间隔的惰轮支撑轨道。 它们形成具有凸起的前部和平坦后部的三角形构造。 非刚性框架提供位于轨道前部和后部的互连的弹性板簧支撑件。 无限轨道通过前后空转轮在驱动齿轮上保持适当的配置，并且在下方通过由柔性框架支撑的间隔开的滑块摩擦条保持其适当的配置。 可选的中间悬架可以用于在框架部分处具有一对间隔开的前后中间惰轮的滑块。 通过在前后板簧中的多个安装孔来实现调节前轮和后轮的位置相对于轴承座的能力。 这样可以将轨道延长到前面或后面，并且仍然使用相同长度的无尽轨道。
