Transportation Vehicle Steering Apparatus

US Patent:
6308640, Oct 30, 2001
Filed:
Nov 17, 1999
Appl. No.:
9/441757
Inventors:
Christian Weule - Baden, AT
Ralf Krause - Hanau, DE
Holger Stubelt - Frankfurt, DE
Jeffrey J. Schwalm - East McKeesport PA
William K. Cooper - Monroeville PA
Assignee:
DaimlerChrysler AG
International Classification:
B61C 1100
US Classification:
105 722
Abstract:
A guidance apparatus is used on a transit vehicle which includes separate steerable drive tires operated by a central guidance platform having four peripherally mounted wheels follow the contour of a guide rail. The guide wheels are spaced above the roadway on a guideway used by the steerable drive tires thereby providing the capability of both on-track and off-track driving of the vehicle. A steering linkage imparts the linkage of a guide plateform to one steerable drive tire and a drag link transmits the rotary motion to the second steerable drive tire.
