Abstract
Motor operated clutch systems which do not need hydraulics enable these kinds of systems to contribute to higher fuel efficiencies and achieve superior shift performance. The targeted shift performance aims to achieve a natural torque transfer for the driver, meaning that fast and accurate clutch actuation in response to torque commands is required. Additionally, any system must be robust in a variety of environmental conditions. There are, however, many combinations of the different factors that lead to faster torque response, and in reality it is a challenge to find the optimum combination of these factors within the associated cost and layout constraints. In this paper we introduce the optimum combination of factors required for superior clutch torque response. These conditions were derived from simulations of multiple disc clutch pack force input responsiveness performed in the early design stages, along with the use of analytical models and quality engineering methodology.
