Embodiment Construction

[0025] refer to figure 1 with Figure 7, a rail car truck 10 is provided that includes a bolster 18 and a pair of spaced side frames 12, 14 having an opening 16 through which the bolster 18 extends. The bolster 18 has an end portion 20 extending through the side frame opening 16 which is supported by a spring 22 . The bolster 18 includes an upper center plate 26 for receiving one of the lower core plates of the main body 23 of the railcar 25 . Railcar truck 10 includes a pair of side bearings 30 having railcar body supports such as covers 32 configured to contact bolsters 27 of railcar body 23 and to restrain railcar body 25 as it travels along the track. 23 back and forth roll motions. The cover 32 undergoes vertical reciprocating motion as the railcar body 23 rocks back and forth, and remains in constant contact with the railcar body 23 to slow the movement of the railcar body 23 . Rail car truck 10 includes one or more wheel sets 40 , each wheel set 40 including a pair ...

Abstract

In one aspect of the present disclosure, a side bearing is provided for supporting a body of a rail car. The side bearing includes a base for being mounted to a truck of the rail car, a support configured to contact the body of the rail car and move along a vertical axis relative to the base with movement of the body, and at least one resilient foam member configured to deform with movement of the support. The side bearing further includes at least one friction damping member configured to be urged in a direction transverse to the vertical axis against the base by the support and resist movement of the support relative to the base.

Description

technical field [0001] The present disclosure relates to railcars, and more particularly to side bearings that limit roll motion of a body of a railcar. Background technique [0002] A railcar, such as a freight railcar, includes a carbody that can carry bulk materials or finished goods and a pair of trucks having wheelsets with conical wheels that travel along the rails of a railroad track. The carbody has a center sill extending below the carbody, and coupling systems at opposite ends of the center sill to attach the railcar to an adjoining railcar. The railcar body also includes a pair of bolsters extending across the railcar body and intersecting the center beam. [0003] Railcars have a lower center plate at each bolster, and each truck has a bolster with an upper center bowl. During assembly of the railcar, the railcar body is lowered onto the truck such that the lower center pan of the body is received in the upper center pan of the truck. Each truck has a pair of ...
