CA 2109369
There is provided a truck wheel-spacing changing method in which the basic structures of the bogie frame and the truck are not made complicated, and only an improvement of the bearing portion is required; the running stability is not inferior to that of a conventional truck of a fixed wheel-spacing type; and the track includes no moving part and the maintenance of the wheel gauge changing system is easy. The truck is equipped with axle boxes slidably supporting axles extending between side beams of the bogie frame. Axle box receivers are selectively and releasable connected with the axle boxes at a plurality of predetermined positions by locking members. When the truck is moved from the one railway to a junction rail- way, the auxiliary wheels mounted on axle box receivers of the truck engage with running paths and raise the vehicle (truck and vehicle body) except the wheel sets and releasing said locked condition by the locking members. When moved through a region where the track gauge of the junction railway is changing or where spacings of inside or outside guide rails is changing, the wheels are pushed by a pair of guide rails or a pair of junction railway rails and shifted transversely together with the axle boxes relative to the axle. Finally, when the truck is moved completely over the junction railway section, a truck wheel-gpacing changing operation is completed.
