Problems solved by technology

[0003] However, in the bogie as in Patent Document 1, since the bogie frame composed of cross beams and side beams is manufactured by welding heavy steel materials to each other, the weight of the bogie frame increases, and there are costs for steel materials and assembly costs. The problem of high cost

Embodiment Construction

[0030] Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

[0031] (first embodiment)

[0032] figure 1 It is a plan view of the railway vehicle bogie 1 according to the first embodiment of the present invention. figure 2 yes figure 1 The shown side view of the bogie 1 for a railway vehicle. image 3 yes figure 1 The illustrated bogie 1 for a railway vehicle is a cross-sectional view taken along line III-III. Such as Figure 1 ~ Figure 3 As shown, the railway car bogie 1 includes a transverse beam 4 extending in the lateral direction as a truck frame 3 for supporting the vehicle body 2 , but does not include side beams extending in the front-rear direction from both ends of the beam 4 . Front and rear of the beam 4, a pair of front and rear axles 5 are arranged along the transverse direction, and wheels 6 are fixed on both sides of the axle 5 in the transverse direction. Bearings 7 , which rotatably support the...

Abstract

A railway bogie (1) is provided with: a cross beam (4) for supporting a railcar body (2); a pair of front and rear axles (5) positioned in the lateral direction in front and to the rear of the cross beam (4); axle bearings (7) for rotatably supporting the axles (5), and provided on both sides of the axles (5) in the lateral direction; bearing housings (8) for housing the axle bearings (7); and a plate spring (9) extending in the forward-rear direction and supported by both lateral ends of the cross beam (4), and having the ends of the plate spring (9) supported by the bearing housings (8). Therein, the bearing housings (8) have a case part (53) for housing the axle bearings (7), and support parts (56-58) for supporting the plate spring, and the plate spring (9) is supported by the support parts (56-58) at a location in the forward-rear direction farther to the center than the axles (5) are.

Description

technical field [0001] The present invention relates to a bogie for a railway vehicle in which side beams are omitted. Background technique [0002] Under the floor of the vehicle body of a railway vehicle, a bogie for supporting the vehicle body to run on the rails is installed, and in this bogie, the axle box for accommodating the bearing supporting the wheel axle can be displaced in the vertical direction relative to the bogie frame, Supported by axlebox supports. In general, the bogie frame includes a beam extending in the lateral direction and a pair of left and right side beams extending from both ends of the beam in the front-rear direction. A shaft spring composed of coil springs between beams (see Patent Document 1). [0003] However, in the bogie as in Patent Document 1, since the bogie frame composed of cross beams and side beams is manufactured by welding heavy steel materials to each other, the weight of the bogie frame increases, and there are costs for steel...
