Abstract

An actuating linkage for a motor vehicle clutch with a clutch lever which can assume two end positions corresponding to the engaged and the disengaged clutch and at which engages an over-dead-center spring that exerts on the clutch lever a force directed toward a respective end position. In order to reduce the actuating force to be produced by the driver with a strong over-dead-center-point spring, the compensating spring engages at the clutch lever which exerts on the clutch lever a force directed toward the end position corresponding to the disengaged clutch whereby the torque applied on the clutch lever by the compensating spring is smaller with a disengaged clutch than with an engaged clutch.
