Abstract
A friction clutch for a drive train of a motor vehicle driven by an internal combustion engine. The clutch includes a rotatable shaft, a housing, at least one first clutch plate, at least one second clutch plate that is movable axially to a limited extent relative to the at least one first clutch plate to actuate the clutch. An actuating device that has at least one lever that is pivotally-mounted on one of the clutch plates, and at least one bar one end of which is connected to the lever and an opposite end of which is connected by an articulated connection to a different clutch plate to improve the function of the clutch.

A friction clutch for a drive train of a motor vehicle driven by an internal combustion engine, said friction clutch comprising:
- a shaft rotatable about a clutch axis of rotation, a housing, a first clutch plate, a second clutch plate that is movable axially relative to the first clutch plate to actuate the friction clutch, and a clutch actuating device;
- wherein the clutch actuating device includes a lever that is pivotally carried on the first clutch plate, and a bar that is connected on one end to the lever and on an opposite end is connected with a first articulated connection to the second clutch plate;
- and,
- wherein the lever and the bar are located radially at an outer edge of the first clutch plate and the second clutch plate.
A friction clutch comprising:
- a clutch axis of rotation;
- a first clutch plate;
- a second clutch plate, axially movable relative to the first clutch plate to engage the friction clutch;
- and,
- a clutch actuating device comprising:
- a rotatable ring concentric with the clutch axis of rotation,
- a lever, pivotally connected to the first clutch plate and connected to the rotatable ring by an articulated connection;
- and,
- a bar including a first end connected to the lever and a second end connected to the second clutch plate.
A friction clutch comprising:
- a clutch axis of rotation;
- a first clutch plate;
- a second clutch plate, axially movable relative to the first clutch plate to engage the friction clutch;
- and,
- a clutch actuating device comprising:
- a lever, pivotally connected to the first clutch plate;
- and,
- a bar including a first end connected to the lever and a second end connected to the second clutch plate;
- and,
- an articulated connection, wherein:
- the articulated connection is formed by a bearing;
- the bearing has an internal part and an external part, movable relative to the internal part;
- the internal part includes a first recessed rolling section for pivotally receiving the external part;
- the external part includes a second rolling section for engagement with the first recessed rolling section;
- and,
- the first recessed rolling section and the second rolling section have respective different rolling radii.
