Abstract
A centrifugal pendulum which is mounted rotatably around an axis of rotation, having a pendulum flange, a first pendulum mass and a second pendulum mass, wherein the first pendulum mass is spaced apart from the second pendulum mass in the circumferential direction, wherein the pendulum flange includes a first pendulum flange part and a second pendulum flange part, wherein the first pendulum mass is positioned bordering axially on the first pendulum flange part and is coupled with the first pendulum flange part so that it is movable to a limited extent, wherein the second pendulum mass is positioned bordering axially on the second pendulum flange part and is coupled with the second pendulum flange part so that it is movable to a limited extent.
Claims18
A centrifugal pendulum mounted rotatably around an axis of rotation and comprising:
- a pendulum flange, a first pendulum mass and a second pendulum mass,
- the first pendulum mass being spaced apart from the second pendulum mass in a circumferential direction,
- the pendulum flange including a first pendulum flange part, a second pendulum flange part and a third pendulum flange part,
- the first pendulum mass bordering axially on the first pendulum flange part, and coupled with the first pendulum flange part with limited movability,
- the second pendulum mass bordering axially on the second pendulum flange part, and coupled with the second pendulum flange part with limited movability,
- the third pendulum flange part being positioned radially to an inside of the first and second pendulum flange parts,
- the first pendulum flange part, the second pendulum flange part, and the third pendulum flange part being separate pieces, the first pendulum flange part being non-rotatably fixed to the third pendulum flange part by first fasteners, the second pendulum flange part being non-rotatably fixed to the third pendulum flange part by second fasteners.
A centrifugal pendulum mounted rotatably around an axis of rotation and comprising:
- a pendulum flange, a first pendulum mass and a second pendulum mass,
- the first pendulum mass being spaced apart from the second pendulum mass in a circumferential direction,
- the pendulum flange including a first pendulum flange part and a second pendulum flange part,
- the first pendulum mass bordering axially on the first pendulum flange part, and coupled with the first pendulum flange part with limited movability,
