Vehicle adapted to be guided on tracks for the public local passenger traffic with pivotal rear axle and longitudinal guide members for such axle

摘要

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.
