Switchable clutch for passenger car, has clamp bodies staying in effective connection with output element by active acceleration force against force of resilient element, where connection is maintained after loosening switching element

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes an innovative switchable clutch for passenger cars. It uses clamp bodies that maintain a connection between the input and output sides, not only during active engagement but also after the switching element is released. The connection is reliably upheld by utilizing acceleration forces to work against a spring mechanism.

Use CasesContent extracted from patent full text and abstract with AI.

• Automatic transmissions in passenger cars
• Hybrid vehicle drive systems needing selective engagement/disengagement
• Start-stop vehicle features that require seamless clutch operation
• Electric vehicles with auxiliary drive clutches

BenefitsContent extracted from patent full text and abstract with AI.

• Improved reliability and maintaining connection even after switching actuation
• Enhanced driving comfort due to smoother transitions
• Potential for energy savings by reducing unnecessary clutch engagement
• Less wear and tear on clutch components due to intelligent engagement mechanism

Patent Abstract

The clutch (1) has a coupling system (4) for friction- and form-fit connection between a drive element (2) and an output element (3). An actuating system (5) comprises a switching element (6) moved from a switching start position (7) into a switching end position. The coupling system is closed in the end position. Clamp bodies (13) stay in effective connection with the output element by an active acceleration force against a force of a resilient element. The effective connection is maintained after deactuating the actuating system and loosening the switching element from the end position.
