    摘要： A track wheel consisting of a longitudinal curved track mounted in an ovaleometry on two support rollers. The track wheel is in effect an oval wheel with two axles. The axles of the two support rollers are mounted either directly or indirectly to the vehicle. The rollers support and guide both ends of the track in the small curvatures and transfers vehicle load to a surface at the lower curved part of the track. The track will withstand a high bending load in one direction, where it engages a surface, but it will also bend easily in the other direction, as it is guided over the two support rollers.

    摘要： A stop member limits deflection of the outer end portions of track shoes of endless track assemblies, which support and propel earthmoving vehicles. Track-type earthmoving vehicles which use wide track shoes often experience wear and structural failures within the track assemblies as a result of vertical loading at the outer end portions of the shoes. The vertical loading of the shoes produces twisting and deflection which is transmitted to the other components of the track assembly, such as the links, pins, bushings, and seals. The deflection stop of the present invention is secured to the trailing end of a first shoe and overlaps a portion of the leading end of a second shoe. As a vertical load is applied to the second shoe, the leading end contacts the deflection stop and the load applied to the second shoe is shared with the first shoe and deflection of the second shoe is minimized.

    摘要翻译： 止动构件限制支撑并推进挖掘车辆的环形轨道组件的履带板的外端部的偏转。 使用宽履带板的履带式土方机车由于在鞋的外端部处的垂直装载而经常在履带组件内经受磨损和结构故障。 鞋的垂直加载产生扭曲和偏转，其被传递到轨道组件的其它部件，例如连杆，销，衬套和密封件。 本发明的偏转止动件固定到第一鞋的后端并与第二鞋的前端的一部分重叠。 当垂直载荷施加到第二鞋时，前端接触偏转止动件，并且施加到第二鞋的负载与第一鞋共享，并且使第二鞋的偏转最小化。
