Appl. No.:

13/712810

Inventors:

STANDARD CAR TRUCK COMPANY - Park Ridge IL, US
Robert Lee Bullock - Loudon TN, US

Assignee:

STANDARD CAR TRUCK COMPANY - Park Ridge IL

International Classification:

B60P 3/079
B60P 3/077

US Classification:

410 10, 410 30

Abstract:

A wheel chock body for a wheel chock that has low elevational profile. The low profile of a wheel chock allows it to be positioned under a vehicle the rocker panel of which has its lower edge only 148 mm (5.82 inches) above the surface upon which the vehicle's tire rests, so that the installed chock height is reduced to 47.6 mm (1.87 inches) under the components of the vehicle's body.

US Classification:

105197DB

Abstract:

A railroad truck side frame includes spaced tension and compression members connected by vertical columns. The tension and compression members, as well as the vertical columns, define a window and there is a bolster extending through the window. One side of each vertical column has a widened area, with the opposite side of each vertical column being substantially coplanar with the side frame. The bolster has lugs projecting from both sides thereof on opposite sides of each column, with the space between lugs on each side of the bolster being substantially greater than the width of the side frame and slightly greater than the distance between the outside of the widened area and the opposite side of the vertical column.

International Classification:

B61F 308
B61F 538
B61F 500

US Classification:

105168

Abstract:

A railroad truck includes a pair of side frames with wheeled axles mounted there between. A roller bearing adaptor is mounted upon a roller bearing at each end of each axle with the side frames being mounted upon a shear pad mounted on the roller bearing adaptors. There is a subframe for interconnecting the wheeled axles by connecting opposite corner adaptors and there is a rigid connection between each adaptor and the subframe. Each rigid connection includes an adaptor portion and a subframe portion, with said portions being relatively vertically disposed. There are vertical fastening means connecting said vertically disposed adaptor and subframe portions. The vertically disposed portions have cooperating means thereon which substantially eliminate horizontal shear forces upon the fastening means.

US Classification:

105197DB

Abstract:

A friction member for use in the bolster pocket of a stabilized railroad car truck has a slanted friction surface adapted to bear against the bolster within the bolster pocket and a vertical friction surface adapted to bear against the side frame. The slanted friction surface has a generally flat portion at the lower end thereof and a generally arcuate portion at the upper end thereof. The two portions of the slanted friction surface are tangent, one to another, with the point of tangency being located so as to insure full contact between the vertical friction surface and the adjacent side frame.

US Classification:

105197DB

Abstract:

A stabilized railroad car truck has a side frame with a window, a bolster extending into the window, a stabilizer pocket on each side of the bolster and a friction element in each pocket. The spring means constitute coaxially positioned spring assemblies supporting each friction element provide generally constant column pressure from each friction element onto its associated side frame wearing area from no load up until approximately half-load, with linearly increasing column pressure from approximately half-load up until full load.

US Classification:

1052241

Abstract:

A railroad car truck has a pair of wheelsets and means for providing relative restraint between wheelsets. A pair of side frames are supported on the wheelsets through resilient pads with the resilient pads providing greater shear resistance in a lateral direction than in a longitudinal direction.

US Classification:

105230

Abstract:

A railroad car truck bolster has a centrally disposed vertically arranged longitudinally extending web. The web has spaced reinforcing means with the spacing of the reinforcing means being sufficient to cause certain fractures in the web propagating along lines of maximum shear stress at approximately 45 degrees to lines of principal stress to reach a reinforcing means at a point closer to the neutral axis of the web than the next adjacent external surface of the web. The bolster side walls have openings with the above-described spaced web reinforcing means being generally in alignment with the bolster side wall openings.

International Classification:

B61F 538
B61F 530

US Classification:

105168

Abstract:

A frameless self-steering radial wheeled support vehicle for a railroad car body includes: (a) a pair of wheelsets, (b) a support at opposite ends of each wheelset for independently mounting a railroad car body on each end of the wheelset, (c) resilient shear pads for mounting each support upon an end of a wheelset, which pads permit both lateral and yaw movement of a wheelset relative to its supports, and (d) a linkage connecting adjacent ends of each wheelset constraining the wheelsets to yaw in opposite sense and permitting lateral movement of one wheelset relative to the other.
