Abstract
This paper describes a long-travel, greased-filled, torsional coupling for use in reducing driveline torsional vibration in vehicles equipped with Continuously Variable Transmissions (CVTs). Desired spring rate and damping of the coupling are determined by computer simulation of the vehicle driveline response during steady-state and transient modes of vehicle operation. Subsequent vehicle testing of prototype couplings show that temperature, grease volume, and seal damping are additional factors in the resulting coupling performance.
