ABSTRACT:
In an undercarriage for a multiple-axle, cross-country vehicle, the connection between the vehicle chassis and a support member for the undercarriage is effected through a mechanism including tension member. The mechanism includes two parallel guides with an integrated hydraulic cylinder each. Each parallel guide has at its lower end a fork member in which an eccentric disk is eccentrically mounted. Each eccentric disk is connected to a drive disk, the center of the drive disk coinciding with a point on the eccentric disk located diametrically opposite the eccentric points. Also connected to the lower end of each parallel guide is a control disk. The two eccentric disks are coupled with each other through a first tension member. The control disks are coupled to the drive disk on the opposite parallel guide by means of a second member. When all structural components of the mechanism are correctly mounted relative to each other, the center points of the eccentric disks maintain the spacing between each other independently of the relative position of the parallel guides, so that the connection to the undercarriage support can be effected through simple pivot bearings. The undercarriage support can be divided into two parts with a roller-type connection between the two parts.
