The guide wheels are spaced above the roadway on a guideway used by the steerable drive tires thereby providing the capability of both on-track and off-track driving of the vehicle. A steering linkage imparts the linkage of a guide plateform to one steerable drive tire and a drag link transmits the rotary motion to the second steerable drive tire.Type: GrantFiled: November 17, 1999Date of Patent: October 30, 2001Assignee: DaimlerChrysler AGInventors: Christian Weule, Ralf Krause, Holger Stubelt, Jeffrey J.

Patent number: 6298792Abstract: An improved hi-rail wheel assembly includes a frame connected to an axle tube surrounding an axle, a pair of railway wheels mounted in spaced relation on the axle tube, a first pair of pivotal links connected between a frame and the axle, and a second pair of pivotal links connected to the frame and the axle. The hi-rail wheel assembly is attached to a conventional roadway vehicle such that the extension of said pivotal links effects a downward lowering of the axle and the railway wheels from the frame and lifts the vehicle whereby the vehicle tires engage the railroad track, and the retraction of the pivotal links effects an upward lifting of the axle and railway wheels towards the frame such that the vehicle tires engage a ground surface or roadway. Each pivotal link includes a cam aperture and a recessed cam shoulder surrounding the cam aperture to receive a cam.Type: GrantFiled: February 24, 2000Date of Patent: October 9, 2001Assignee: ESSCOInventor: Robert D. Jackson, Jr.
