Abstract (en)

[origin: WO2012175186A1] A lever spring for a clutch, in particular a friction clutch having a wear compensation device, for a motor vehicle, comprises lever elements for transmitting a force for opening or closing the clutch, and a force edge which is connected to the lever elements, wherein the lever spring has an upright height h0 and a thickness s. According to the invention, the lever spring is embodied as a snap-action spring. By snapping over the lever spring, in particular the force edge, the required engagement force for actuating the lever spring and for opening the friction clutch can be significantly reduced.
