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.

Abstract: A transmission apparatus converts rotational motion into technically linear motion and can be used for vertically displacing wheels or tracks on an off-the-road vehicle. The transmission apparatus includes at least one stationarily mounted control disk with at least a circular arc section on its circumferential periphery and at least one eccentric disk connected to the control disk by a drive device. The eccentric disk has a circular circumferential periphery and an eccentric point from its center point. The eccentric disk is rotatably connected to one end of an elongated rocker arm. The other end of the rocker arm is pivotally connected to the control disk at a point on a straight line extending between the center of curvature of the circumferential periphery of the control disk and the disengaging point of the drive member from the circumferential periphery of the control disk in the neutral position of the eccentric disk.
