The Traveling Chain Transmission (TCT) is a novel two-speed chain drive developed at the General Motors R&D Center [1]. In order to predict potential performance and develop design requirements, a multi-body dynamic model of the Traveling Chain Transmission (TCT) was developed and validated using dynamometer test data from the first TCT prototype hardware. A vehicle drivetrain model incorporating the TCT as part of a multi-speed transmission was also developed in order to study the potential performance of the TCT in a vehicle environment. The simulated transmission is a nominal 4-speed automatic transmission converted to a 5-speed transmission by replacing the fixed speed-ratio drop chain by the dual speed-ratio TCT. An upshift from 4th to 5th gear is simulated and the resulting torque and speed transients are predicted.
