Assignee:
General Motors Corporation - Detroit MI
International Classification:
B61D 100
US Classification:
105166, 105 341

Arrangement Of Radial Bogie

US Patent:
6871598, Mar 29, 2005
Filed:
Jun 14, 2002
Appl. No.:
10/172806
Inventors:
Hans-Dieter Schaller - La Grange IL,
Xiaoying Ma - Itasca IL,
David Jason Goding - Palos Park IL,
Assignee:
General Motors Corporation - Detroit MI
International Classification:
B61F005/00
US Classification:
105168, 105167, 105 341, 1051571
Abstract:
An arrangement for self-steering, radial bogie, truck or vehicle frame for locomotives and other railroad vehicles, which includes steering beams for and located behind their respective leading and trailing wheelsets, and whose rotary motions are coupled by an inter-axle link to provide opposite transverse movement of the first and third wheelsets upon traversing curves.

Self-Steering Radial Bogie

US Patent:
2010001, Jan 21, 2010
Filed:
Jul 16, 2009
Appl. No.:
12/504516
Inventors:
Hans-Dieter Schaller - LaGrange IL,
Xiaoying Ma - Burr Ridge IL,
International Classification:
B61F 5/38
B61F 3/00
B61F 5/50
US Classification:
105168
Abstract:
A self-steering system for a radial bogie of a railroad vehicle is provided. The self-steering system includes a plurality of links which connect the leading and trailing wheelsets to the bogie frame. Each of the links is adapted to provide a smaller degree of movement between the link and the wheelset at one end and a larger degree of movement between the link and the bogie frame at the other end.

Locomotive Adhesion Enhancing Slipping Discs

US Patent:
5775228, Jul 7, 1998
Filed:
Apr 14, 1997
Appl. No.:
8/843320
Inventors:
Harinder Singh Lamba - Downers Grove IL
Robert Thomas Scott - Lockport IL
Xiaoying Sean Ma - Chicago IL
Assignee:
General Motors Corporation - Detroit MI
International Classification:
B61C 1500
US Classification:
105 73
Abstract:
At least one powered disc is suspended from a locomotive and applied to a rail surface for treating the rail surface ahead of driven locomotive wheels to increase adhesion between the driven wheels and the rail surface. Torque applied to the disc varies the rate of rotation of the disc away from that of a freely-rotating disc so that a significant level of creep may be maintained between the disc and the rail surface with substantially no angle of attack between the disc and the longitudinal axis of the rail. The torque may be generated through a second disc contacting the rail and coupled to the first disc with the first and second discs rotating with differing rates of rotation, or may be generated through a passive or active actuator coupled directly to the disc. The amount of creep between the disc and the rail surface and the direction of the creep may be varied in accordance with the level of contamination of the rail and the disc may be disengaged from the rail when cleaning is not required.
