    • A chassis with variable track, particularly suited to agricultural machinery and equipment with at least four wheels, all or partly steered and all or partly driven, characterized in that it comprises a central horizontal frame, rectangular in plan view, which supports the various parts (C, P, S and B) of the agricultural machine (M) and which is provided laterally with side members (2 and 2') parallel to the stringers of said frame, having a U-shape in plan, and having end sections that carry outwardly facing mounts or hubs (102 and 102') for supporting the suspensions of the wheels (R1 and R2) of said machine (M), the longitudinal section of said side members (2 and 2') being equipped with at least one pair of slides or axle boxes (3 and 3') sliding on associated guide rods (4 and 4') supported at the ends by cross members (5 and 5') fastened to said central frame (1) and laterally and equally projecting therefrom, with drive means being provided that are connected by one side to said central frame (1) and by the other side to said side members (2 and 2') to move these side members (2 and 2') from a minimum track position, where they are close to the sides of said central frame (1), to a maximum track position, where they are at the maximum distance from the central frame (1), or to intermediate positions, with a parallel and as far as possible synchronized displacement of the side members (2 and 2').

    • A wheel unit (101) comprising one or several wheels (102, 103) being arranged for rotation about at least one wheel axle (104) during movement of the wheel unit along a support surface (105), wherein the wheel axle can be brought into different turning positions about a turning axis (106) extending substantially perpendicularly to the wheel axle, and wherein the wheel unit further comprises at least one turning means for controlling the turning position. The wheel axle (104) is adapted for axial displacement (Y) relative to the turning axis (106) in dependence upon external forces (F) acting on the wheel/wheels (102, 103) and/or on the turning axis (106), by means of the wheel axle being interconnected with the turning axis via a sliding device, wherein the turning means (108) is adapted for returning the axial displacement toward a normal position during the movement along the support surface by means of said control of the turning position.
    • 轮子单元(101)包括一个或多个轮(102,103),其被布置成在轮单元沿着支撑表面(105)移动期间围绕至少一个轮轴(104)旋转,其中可以带来轮轴 围绕基本上垂直于所述轮轴延伸的转动轴线(106)进入不同的转动位置,并且其中所述车轮单元还包括用于控制所述转动位置的至少一个转动装置。 轮轴(104)适于根据作用在车轮/车轮(102,103)和/或转动轴线(106)上的外力(F)相对于转动轴线(106)的轴向位移(Y) ),通过所述轮轴通过滑动装置与所述转动轴线相互连接,其中所述转动装置(108)适于通过所述控制装置(108)沿所述支撑表面的运动期间使所述轴向位移朝向正常位置返回 转弯位置。
