    Abstract: A vehicle steering system includes a steering input device, a front steering subsystem, a rear steering subsystem, a first force transmission route, a steering control mechanism, a second force transmission route, and a third force transmission route. The front steering subsystem is coupled to front motive members to steer the front motive members based upon movement of a front steering subsystem input shaft. The rear steering subsystem is coupled to rear motive members to steer the rear motive members based upon movement of a rear steering subsystem input shaft. The first force transmission route extends from the steering input device to the front steering subsystem input shaft, wherein force is transmitted from the input device to the front steering subsystem input shaft to steer the front motive members. The steering control mechanism has a movable input member and a movable output member. The movable input member is movable through a first distance without transmitting force to the output member and is movable through a second distance in which force is transmitted to the output member to move the output member. The second force transmission route extends from the steering input device to the input member, wherein force is transmitted from the input device to the input member to move the input member. The third force transmission route extends from the output member to the rear steering subsystem input shaft to move the rear steering subsystem input shaft and to steer the rear motive members.

    Abstract: A non-pneumatic tire for supporting a load by working in tension comprising a generally annular inner ring, a generally annular outer ring, and an interconnected web having a plurality of web elements and comprising a plurality of generally polygonal openings. Web elements are sized, oriented and comprised of a material that facilitates buckling when subjected to a compressive load. By buckling, those elements in a deformed portion of the tire between a wheel and a footprint region where the tire contacts a surface can assume a significantly reduced portion of the load, if any. This causes web elements in other portions of the interconnected web to operate in tension to support the load.

    Abstract: An agricultural implement is provided that includes a hitch assembly configured to couple the agricultural implement to a tow vehicle, and a carrier frame pivotally coupled to the hitch assembly. The agricultural implement also includes a pair of wheel assemblies each rotatably coupled to the carrier frame by a respective pivot joint. The agricultural implement further includes an actuator assembly configured to rotate each wheel assembly about the respective pivot joint in a first direction by applying a first torque, and to rotate each wheel assembly about the respective pivot joint in a second direction, opposite the first direction, by applying a second torque. A magnitude of the first torque and a magnitude of the second torque are substantially equal.

    Abstract: A non-pneumatic tire for supporting a load by working in tension comprising a generally annular inner surface, a generally annular outer ring, and an interconnected web having a plurality of web elements and comprising a plurality of generally polygonal openings. Web elements are sized, oriented and comprised of a material that facilitates buckling when subjected to a compressive load. By buckling, those elements in a deformed portion of the tire between a hub and a footprint region where the tire contacts a surface may assume a significantly reduced portion of the load, if any. This causes web elements in other portions of the interconnected web to operate in tension to support the load. Since the tire is non-pneumatic, it may be easier to maintain and may have a longer life than standard pneumatic tires since it eliminates the possibility of blowouts, flat tires, or tires operating with low air pressure. By virtue of the portion of the tire in the footprint region not bearing a significant portion of the load, non-pneumatic tire may also exhibit a more comfortable ride subject to less noise and vibration and improved handling capabilities.

    Abstract translation: 一种非充气轮胎,用于通过在张力下工作来支撑负载,包括大致环形的内表面,大体上环形的外圈,以及具有多个腹板元件并且包括多个大体上多边形的开口的互连腹板。 网元件的尺寸,取向和由承受压缩载荷时有利于屈曲的材料构成。 通过弯曲,在轮毂和轮胎与表面接触的覆盖区域之间的轮胎的变形部分中的那些元件可以承受负载的显着减少的部分(如果有的话)。 这导致互连网的其他部分中的网状元件在张力下操作以支撑负载。 由于轮胎是非气动的,因此它可以比标准充气轮胎更容易维护并且可以具有更长的使用寿命,因为它消除了排气孔,扁平轮胎或低空气压力下运行的轮胎的可能性。 由于轮胎在足迹区域中不承载大部分负载的部分,所以非充气轮胎也可以呈现更舒适的乘坐体,具有更少的噪音和振动以及改进的处理能力。
