LTV/SIG METROLINER TRUCK. FINAL DESIGN REPORT

The Vought Systems Division of the LTV Aerospace Corp. (LTV) in association with the Swiss Industrial Company (SIG) of Neuhausen Rhine Falls, Switzerland, has designed, manufactured, and tested the LTV/SIG Truck under contract to the Department of Transportation (DOT). The LTV/SIG Metroliner Truck design was derived from the SIG M-Type Truck. The primary design objective of the program, performed under contract to DOT, was to provide a truck having improved ride comfort at speeds to 160 mph for the Penn Central Metroliner route. The design features a welded steel frame and bolsters, a coil spring/bellcrank primary suspension, an air spring secondary suspension, and elastomeric components to minimize noise/vibration transmission. A worn wheel profile is used with its attendant advantages in wear and maintenance. Truck designs were completed to allow the use of either General Electric or Westinghouse propulsion systems. However, only the former configuration was completed through final assembly due to the unavailability of government-furnished Westinghouse traction equipment. Because most of the analysis and design was done in Switzerland, the metric notation is used extensively in this report.
