Patent number: 7934997Abstract: The present invention broadly comprises a torque limiter including a sealed vessel with a damper assembly and a clutch arranged to receive torque from a drive unit and to transmit the torque to the damper assembly. The clutch is loaded independent of an engagement of the limiter with the drive unit. A reaction force between a resilient element in the clutch and the vessel preloads the clutch. The clutch is arranged to slip at a specified torque value. The resilient element is arranged to preload the clutch such that the clutch remains fully engaged up to the specified torque value. In some aspects, the limiter includes a drive unit connection plate and the clutch is disposed between the connection plate and the vessel. In some aspects, the vessel includes a housing connected to the connection plate and the clutch is disposed between the housing and the damper assembly.Type: GrantFiled: November 20, 2007Date of Patent: May 3, 2011Assignee: Schaeffler Technologies GmbH & Co.
