Patent

CA 2449599

A dual use roadway or railroad travel vehicle such as a railcar mover (10) is disclosed which includes an inner set (24) of wheel assemblies (28, 30) designed for alternate roadway or rail travel, together with fore and aft rail wheel assemblies (32, 34) which may be alternately retracted for roadway travel or lowered for rail travel. The wheel assemblies (32, 34) each have a pair of rail wheels (36, 38) mounted on fixed spindles (48) so that the rotational axes A of the wheels (36, 38) are oriented at an oblique angle .alpha. of less than 6° relative to the horizontal H; this wheel orientation, together with a rail wheel geometry including a rim surface (40, 42) parallel with the associated rotational axis A and a reduced radius of curvature R between the rim surface (40, 42) and the flange (44, 46), significantly decreases the problem of rail wheel climb encountered with conventional movers (10), while also reducing flange wear.
