    • The present invention relates to an arrangement in a wheel lifting mechanism designed to lift at least one wheel (1) running on an underlying surface so that it is capable of negotiating an obstacle (h) rising above the underlying surface. The arrangement comprises an element (7) which is formed with a contour convexly curved towards the underlying surface and is moveably supported in relation to the axle of the wheel (1). The said element is designed, when the contour of the element (7) engages with the obstacle (h), to bring about the said lifting of the wheel (7) as the element (7) is rotated about its point of engagement with the obstacle (h). The arrangement further comprises a chassis (4), to which the wheel axle is firmly connected. Between the chassis and the element (7) there is an operative connection designed, when the element (7) engages with the obstacle (h), to allow the chassis (4) firstly to undertake lifting of the wheel (1) from a home position of the element (7) during a displacing movement relative thereto in the direction of movement of the wheel, and secondly to bring about a return to the home position once the wheel (1) has been lifted to the level of the obstacle (h).
    • 本发明涉及一种车轮提升机构中的布置,其被设计用于提升在下面的表面上运行的至少一个轮(1),使得其能够协商在下面的表面上方升起的障碍物(h)。 该装置包括一个元件(7),该元件(7)形成有朝着下面的表面凸出地弯曲的轮廓,并相对于车轮(1)的轴可动地支撑。 当元件(7)的轮廓与障碍物(h)接合时,所述元件设计成当元件(7)围绕其与所述障碍物(7)的接合点旋转时实现所述轮(7)的所述提升, 障碍(h)。 该装置还包括一个底盘(4),轮轴牢固地连接到该底盘上。 在底盘和元件(7)之间,当元件(7)与障碍物(h)啮合时,有一个可操作的连接设计,以允许底盘(4)首先从一个家中提起车轮(1) 元件(7)在相对于其移动方向相对于其移动方向的移动方向上的元件(7)的位置,其次,一旦车轮(1)已被提升到障碍物的水平面(h )。
