    Abstract: A tracked ATV (10) includes a frame (30), a track (12, 14) coupled to the frame (30), and a power source supported by the frame and drivingly coupled to the track. The tracked ATV further includes a steering and drive assembly, which has a first hydraulic pump coupled to the tracks (12, 14) for large radius turns. The steering and drive assembly also has a second hydraulic pump coupled to the tracks (12, 14) for small radius turns.

    Abstract: A non-pneumatic tire is disclosed where a resilient wheel is mounted on a rim and the wheel has an inner ring (8), an outer ring (10) and a plurality of flexible webs interconnected between the inner and outer rings. The flexible webs define openings (12,14,16,18,20) in through the resilient wheel. The stiffness of the inner wheel at a position adjacent to the inner face (316) is different than the stiffness of the inner wheel at a position adjacent to the outer face (314). This stiffness difference can be accomplished by providing inflated membranes (225, 225 1 ) in at least some of the openings or by molding the wheel with an asymmetric parting line. In addition, the wheels could be dynamically controlled by providing magnetically actuable membranes in some of the openings.

    Abstract translation: 公开了一种非充气轮胎,其中弹性轮安装在轮辋上,并且轮具有内圈(8),外圈(10)和在内圈和外圈之间互连的多个柔性腹板。 柔性腹板限定穿过弹性轮的开口(12,14,16,18,20)。 在与内表面(316)相邻的位置处的内轮的刚度不同于内轮在与外表面(314)相邻的位置处的刚度。 这种刚度差可以通过在至少一些开口中提供充气膜(225,2521)或通过用不对称分型线模制车轮来实现。 此外,可以通过在一些开口中设置可磁致动的膜来动态地控制车轮。
