Embodiment Construction

[0038] See below Figure 3-11 The first embodiment of the side support of the present invention will be described. The side support assembly 100 has a main longitudinal axis coincident with the longitudinal axis of the rail car. That is, when the side support is installed on the rail car bogie bolster 38, the main axis of the side support is perpendicular to the longitudinal axis of the bolster. The side support assembly 100 includes a base 110 as main elements, a cap 120, one or more elastic propulsion elements 130 (such as springs or elastomer elements), and a spring base 131. In the illustrated exemplary embodiment, two springs are provided, an outer spring 130A and an inner spring 130B used as a propulsion element, and each spring may have a different spring constant to provide a total combined rated load.

[0039] The base 110 is fixed to the bolster 38 with suitable devices. As shown in the figure, the base 110 is bolted to the bolster 38 with a mounting bolt (not shown) ...

Abstract

A long travel constant contact side bearing for railway cars provides better handling characteristics, achieving improved tracking and curving through use of various combinations of features. The sidebearing comprises a base and a generally cylindrical wall section extending upwardly from the base. A cup-shaped cap comprises a generally circular top section and a generally cylindrical wall sectionextending downwardly therefrom. The cap extends into the wall section of the base. At least one coil spring is provided within the base and extends to the underside of the cap.

Description

Technical field [0001] The present invention relates to an improved side support design installed on a rail car bogie bolster. This design allows long displacement, significant weight reduction, improved tortuous driving and turning characteristics, and various convenient installation features. Background technique [0002] In such figure 1 In the typical train of railway freight cars shown, the rail cars 12, 14 are connected end-to-end by connectors 16,18. Each of the connectors 16, 18 is received in the traction beam 20, 22 of each corresponding vehicle together with a hydraulic buffer or traction gear assembly (not shown). The traction beams 20, 22 are arranged at the ends of the center beams of the rail car, and include a center plate placed in the center plate bowl of the rail car bogies 26, 28. [0003] Such as figure 2 As shown well, each typical rail car bogie 26 includes a pair of side frames 30, 32 supported on wheel sets 34, 265. The bolster 38 extends between the spr...
