Ratcheting One-Way Clutches in Torque Converters

This paper discusses a new development in one way clutches (OWC), ratcheting OWC in torque converters (TC). While this has been tried before, and been successful in niche applications, it has not been introduced into mass production. Ford Motor Company has worked to develop a ratcheting OWC for use in TC. The efficiency of ratcheting OWC is better than friction type OWC. Ford Motor Company is working to implement ratcheting OWC into their torque converters, replacing friction type OWC.
