Problems solved by technology

Specifically, the length of the springs that can be used with the frame may be limited by the position of the top plate since the springs push against the base at the top plate
Furthermore, the '579 patent does not disclose a method of limiting separation of the bearing housing from the frame or limiting lateral movement of the frame
Also, separating the frame into two cast parts may not significantly reduce the production cost of the frame

Embodiment Construction

[0014] figure 1 An exemplary locomotive 10 is shown that includes a car body 12 supported by a plurality of bogies 14 (e.g., two bogies 14) at opposite ends. Each bogie 14 may be configured as a base platform 16 that engages a rail (not shown) and supports the vehicle body 12. Any number of engines may be mounted on the base platform 16 and configured to drive the multiple wheels 18 contained in each bogie 14. in figure 1 In the exemplary embodiment shown, the locomotive 10 includes a first engine 20 and a second engine 22 longitudinally aligned on a base platform 16 in the direction of travel of the locomotive 10. However, those skilled in the art will recognize that the first engine 20 and the second engine 22 may be disposed on the base platform 16 laterally or in any other direction.

[0015] The vehicle body 12 may be fixedly or detachably connected with the base platform 16 so as to substantially surround the first engine 20 and the second engine 22 while also providing ma...

Abstract

A frame for use with a railway truck having a plurality of support springs is provided. The frame may have a bottom section with a plurality of first openings configured to receive the plurality of support springs, and a middle section welded to the bottom section. The frame may also have a top section spaced apart from the bottom section and welded to the middle section. The top section may have a plurality of second openings configured to register with the plurality of first openings in the bottom section, and a plurality of protrusions extending away from the middle section at the plurality of second openings to enclose exposed ends of the plurality of support springs.

Description

Technical field [0001] The present invention relates generally to a vehicle frame, and more particularly to a fabricated vehicle frame for railway bogies. Background technique [0002] Locomotives traditionally include a body that houses one or more power plants of the locomotive. The weight of the car body is supported at either end by bogies, which transfer the weight to opposite tracks. The bogie usually includes a cast steel frame, which provides installation for the traction motor, axle and wheel set. Locomotives can be equipped with bogies with two, three or four axles. Although suitable for many applications, cast bogie frames can be expensive, especially when produced in low quantities for specialized applications. [0003] Japanese Patent No. 2000085579A ("579 Patent") published by Hitachi Group on March 28, 2000 discloses an exemplary fabricated locomotive bogie. Specifically, the '579 patent discloses a frame assembled by welding a cast upper plate to a cast lower pl...
