Abstract

Dry clutches are widely used in conventional and innovative automotive drivelines and represent a key element for automated manual transmissions (AMTs). In practical applications, it is fundamental to model the clutch behavior through its torque transmissibility characteristic, i.e., the relationship between the  throwout  bearing  position  (or  the  pressure  applied  by  the clutch actuator) and the torque transmitted through the clutch during the engagement phase. In this research activity we study new models for the torque transmissibility of dry clutches. We analyze how the transmissibility characteristic depends on: friction pads geometry, cushion spring compression, cushion spring load, and slip-speed-dependent friction. Corresponding functions are suitably composed determining the torque transmissibility expression. An experimental procedure for tuning the characteristic parameters can be defined and suitable engagement control algorithms can be designed.
