Patent number: 8596125Abstract: A method and apparatus for collecting ultrasonic test data from a railway wheel with an ultrasonic testing apparatus is described. The railway wheel is supported by two drive rollers, each having an indentation which engages with and rotates the wheel. An indexing transducer moves across the rotating wheel, collecting ultrasonic test data while a fixed transducer correlates a reference position on the wheel to the collected test data. To maintain the accuracy of the reference position to the collected test data, it is desirable to maintain the rotational stability of the wheel, minimizing any dynamic instability caused by dimensional tolerances in the wheel. To mitigate instabilities resulting from dimensional tolerances, the indentation of the drive rollers, which engage and drive the flange of the wheel, are variably spaced using a resilient member to maintain frictional contact between the wheel and the drive roller.Type: GrantFiled: June 23, 2011Date of Patent: December 3, 2013Assignee: Amsted Rail Company, Inc.Inventors: John R Oliver, John D.

To mitigate instabilities resulting from dimensional tolerances, the indentation of the drive rollers, which engage and drive the flange of the wheel, is adjustable by the flexing design of the drive rollers to maintain frictional contact between the wheel and the drive roller.Type: GrantFiled: July 19, 2011Date of Patent: December 3, 2013Assignee: Amsted Rail Company, Inc.Inventors: John R.

Patent number: 6371033Abstract: A three piece stabilized railway car truck is provided with dimensions corresponding generally with an AAR nominal 100 ton size truck and a load carrying capability satisfactory for use with railway cars having a 315,000 pound gross weight on rail rating. Various components of the truck have been modified to improve the fatigue life of each component and the overall service life of the resulting railway truck.Type: GrantFiled: October 5, 1999Date of Patent: April 16, 2002Assignees: TRN Business Trust, Amsted Industries Incorporated, The Timken CompanyInventors: Stephen W.

Patent number: 5574233Abstract: The present invention provides a non-contact test apparatus and method for evaluating an as-manufactured railway wheel, which apparatus has a plurality of non-contact sensors positionable in proximity to various wheel locations and coupled to a controller for communication of a plurality of sensed dimensional parametric signals for comparison to specified wheel reference parameters in the controller to thereby simultaneously evaluate several dimensional parameters and characteristics for qualification of a railway wheel satisfying AAR specifications for railway wheels.Type: GrantFiled: October 17, 1994Date of Patent: November 12, 1996Assignee: Amsted Industries IncorporatedInventors: John D. Oliver, Roger M. Whitson
