摘要： The object is to solve the issue of an over-steered state at an exit straight portion in addition to enhance a curve passage performance than when a steering angle of front and rear axles is set at a radial steering angle. A steering method for a steering device intentionally turns two axles (11a, 11b) of a truck (12) of a railway vehicle relative to a frame of the truck. The two axles are arranged at front and rear of the truck with respect to a direction of running of the railway vehicle. The steering method includes steering the axles such that a steering angle (α1) of the front axle (11a) is larger than a steering angle (α2) of the rear axle (11b).

摘要： A bogie frame for railway vehicles includes a pair of left and right side frames disposed along a direction of rails and a cross frame that connects the side frames to each other, and the cross frame includes a top plate member, a bottom plate member, and a pair of front and rear side plate members that are disposed between these plate members and welded thereto, wherein the cross frame has mounting bracket support portions that extend from front and rear edges of the top plate member and the bottom plate member, correspondingly to locations where mounting brackets for mounting a traction motor and mounting brackets for mounting a gearbox are disposed, and the mounting brackets are welded to the mounting bracket support portions. This makes it possible to achieve good welding workability for assembling the bogie frame.

The two axles are arranged at front and rear of the truck with respect to a direction of running of the railway vehicle.

摘要： A bogie frame for railway vehicles includes: a pair of left and right side beams disposed along a direction of rails; a cross beam that connects the side beams to each other; and a mounting bracket for mounting a functional part, the mounting bracket being joined to the cross beam, wherein the cross beam has a rectangular cross section and includes a top plate section, a bottom plate section, and a pair of side plate sections; the top plate section has a cutout opening extending to one of the side plate sections; the mounting bracket is inserted in the cutout opening; and the mounting bracket and the top plate section are joined together by butt welding. This configuration enhances welding workability for welding mounting brackets for mounting functional parts such as a traction motor, a gearbox, and a brake, and allows a greater degree of design flexibility for the positions where functional parts are mounted.
