US Patent:

6591759, Jul 15, 2003

Filed:

Nov 28, 2001

Appl. No.:

09/995541

Inventors:

Robert L. Bullock - Loudon TN

Assignee:

Standard Car Truck Company - Park Ridge IL

International Classification:

B61F 526

US Classification:

1052241

Abstract:

A shear pad assembly for use between a rail car side frame pedestal and the rail car roller bearing adapter includes an upper plate formed and adapted to seat the side frame pedestal and a lower plate, spaced from the upper plate, and formed and adapted to seat on the roller bearing adapter. There is an elastomer positioned in the space between the upper plate and the lower plate, with the elastomer having a generally uniform thickness throughout a substantial portion of the space between the plates. There are a pair of spaced metal shims, each extending parallel to a side frame, being adjacent an edge of the elastomer, and being located generally intermediate the upper and lower plates.

Inventors:

Robert Lee Bullock - Loudon TN 37774-6806

International Classification:

B61F 1500

US Classification:

1051821, 10519705, 105207

Abstract:

Yaw stabilization device provides a light-weight mechanism for increasing the linear yaw stiffness levels between the side frame and bolster to provide the proper inter-axle shear stiffness without affecting the compliancy required of the vertical suspension system. This invention, which fails to increase the unsprung weight of a railroad car truck assembly noticeably, may be retrofitted to existing freight car trucks in service or incorporated into newly manufactured trucks. Moreover, it does so without the need for damping wedges to increase interaxle shear stiffness and allow the wedges to function optimally for control of vertical vibrations.

Inventors:

Robert Lee Bullock - Loudon TN, US

International Classification:

B60P 7/08

US Classification:

410 10, 410 9, 410 11, 410 12, 410 20

Abstract:

A low elevational profile of each of a pair of first and second wheel chocks for restraining a current “low-drag” motor vehicle in a carrier, such as a railway car, is derived from each wheel chock having an internally webbed, elongated stepped-box body terminated with a relatively short rectangular box having its inner wall integrally formed with the stepped-box body. The body of the first chock is essentially a mirror-image of the second chock body. The low profile of a wheel chock allows each 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″) under the components of the vehicle's body. The assembly may include a pair of “active” chocks; or, one active chock and one anchor chock.
