A vehicle adapted to be selectively operated with or without guide rails with the vehicle including a steerable vehicle axle and at least one nonsteerable vehicle axle. The nonsteerable vehicle axle is mounted so as to be entirely pivotable to a limited extent about a centrally positioned vertically extending pivot axis. At least two longitudinally extending control arms are provided for determining a transverse position of the nonsteerable vehicle axle with the longitudinally extending control arms being constructed so as to be variable in length and at least one of selectively lockable in or releasable from a predetermined length required for an exact transverse positioning of the nonsteerable vehicle axle when the vehicle is operated without guide rails. Each of the longitudinally extending control arms includes at least two doubleacting hydraulic cylinder piston units which are disposed in parallel to a bending resistant guide rod slidably received in a guide bore of a guide housing. An arrangement is provided for selectively locking and releasing the longitudinal control arms in and from the various length extended positions with working chambers of each of the piston-cylinder units being in communication with each other by way of pressure equalizing conduits.
A vehicle adapted to be selectively operated with or without guide rails, the vehicle comprising a steerable vehicle axis means having steerable wheels mounted thereon, at least one nonsteerable vehicle axle having nonsteerable wheels mounted thereon, means for pivotally mounting the nonsteerable axle means so as to be entirely pivotable to a limited extent about a centrally positioned vertically extending pivot axis, and at least two longitudinal control arm means for determining a transverse position of the nonsteerable axle means, said longitudinal control arm means each being constructed so as to be variable in length and selectively lockable in or releasable from a predetermined length required for an exact transverse positioning of the nonsteerable vehicle axle means when the vehicle is operated without guide rails, characterized in that each of the longitudinal control arm means is provided at respective ends thereof with a mounting means, a first mounting means of the respective longitudinal control arm means being operatively connected with a bending-resistant guide rod means and a second of the mounting means being operatively connected with a guide housing means which is provided with a guide bore means for slidably receiving the guide rod means with a predetermined amount of play, at least two double-acting hydraulic piston-cylinder means are provided for each of the longitudinal control arm means, means are provided for operatively connecting each of the hydraulic piston-cylinder means to the first and second mounting means so that the hydraulic piston-cylinder means are disposed in parallel to the guide rod means, the connecting means being arranged eccentrically with respect to at least one of the guide rod means and the guide bore means, means are provided for selectively locking and releasing the longitudinal control arm means in and from an extended position of a predetermined length required for an exact transverse positioning of the nonsteerable vehicle axle means, each of the piston-cylinder means includes working chamber means, and in that means are provided for communicating the respective working chamber means of the cylinder-piston means of the respective longitudinal control arm means with each other.
A longitudinal control arm means for determining a transverse positioning of a nonsteerable vehicle axle means of a vehicle adapted to be selectively operable with or without guide rails, characterized in that the longitudinal control arm means includes a guide housing means having a guide bore means for slidably accommodating a guide rod means therein, at least two double acting piston-cylinder means, means for operatively connecting the piston cylinder means to the guide housing means and the guide rod means such that the piston-cylinder means are disposed in parallel with the guide rod means, the connecting means being arranged eccentrically with respect to at least one of the guide rod means and the guide bore means, and in that means are provided for selectively locking and releasing the longitudinal control arm means in and from an extended position of a predetermined length.
