Embodiment Construction

[0047] Figure 1A A perspective view of a sideframe 100 of a rail car truck is illustrated. A rail vehicle may correspond to a freight car, such as those used in the United States to transport goods with a gross weight in excess of 220,000 lbs (pounds). The side frame 100 includes a bolster aperture 110 and a pair of pedestals 105 .

[0048] The bolster bore 110 is defined by a pair of sideframe uprights 120 , a compression member 125 , and a spring seat 127 . The size of the bolster hole 110 is to accommodate the bolster 700 ( Figure 7 ) of the outboard end portion 705 ( Figure 7 ). A set of springs (not shown) is placed between the outboard end portion 705 of the bolster 700 and the spring seat 127 and resiliently connects the bolster 700 to the side frame 100 .

[0049] A pair of wear plates 135 are positioned between the shoe openings 710 of the outboard end portion 705 of the bolster 700 and the sideframe uprights 120 . For illustration purposes, Figure 1A A singl...

Abstract

A method of manufacturing a side frame of a rail car, where the side frame includes a pair of pedestals for mounting wheel sets, includes providing a side frame pattern for forming a drag portion and a cope portion of a mold. Cores that define an interior region of a cast side frame are also provided. The side frame pattern and the cores are configured to constrain a spacing between the pair of pedestals to within about +-.038 inches.

Description

Background technique [0001] Railcars generally consist of railcars supported on a pair of bogie assemblies. The bogie assembly consists of a pair of sideframes and wheelsets connected together by a bolster and damping system. The car is supported on the central bowl of the bolster, which acts as the pivot point for the bogie system. Movement of the carriage body is resisted by springs and friction wedge dampers that connect the bolsters to the side frames. The sideframes include pedestals respectively defining cutouts into which the wheel assemblies of the wheelsets are seated using roller bearing adapters. [0002] Sideframes and bolsters can be formed by various casting techniques. The most common technique used to produce these elements is by sand casting. Sand casting provides a low-cost, high-volume method for forming composite hollow shapes such as side frames and bolsters. In a typical sand casting operation, (1) the mold is formed by pouring sand around the mold, ...
