Abstract
A centrifugal pendulum for a motor vehicle drivetrain includes a carrier, a pendulum mass, mounting for pivoting relative to the carrier, and a roller body. The carrier has a carrier roller track and the pendulum mass has a pendulum mass roller track. The roller body has a first rolling region arranged in the carrier roller track and a second rolling region arranged in the pendulum mass roller track. The carrier roller track is formed at least partially by an axially formed sheet-metal portion having a free edge, and the free edge faces away from the pendulum mass.
Claims18
A centrifugal pendulum for a motor vehicle drivetrain, comprising a carrier and a pendulum mass, which is mounted for pivoting relative to the carrier by means of at least one roller body, wherein a first rolling region of the at least one roller body is accommodated in a roller track of the carrier and a second rolling region of the at least one roller body is accommodated in a roller track of the pendulum mass, wherein at least one of the two roller tracks is formed partly or completely by an axially formed sheet-metal portion in such a way that a free edge of the axially formed sheet-metal portion faces away from the nearest pendulum mass;
- wherein the formed sheet-metal portion has an area curved by sheet-metal forming, with which a portion of the roller body can be brought into contact and over which the portion of the roller body rolls.
A centrifugal pendulum for a motor vehicle drivetrain, comprising:
- a carrier comprising a carrier roller track;
- a pendulum mass, mounted for pivoting relative to the carrier, the pendulum mass comprising a pendulum mass roller track;
- and
- a roller body comprising:
- a first rolling region arranged in the carrier roller track;
- and
- a second rolling region arranged in the pendulum mass roller track, wherein:
- the carrier roller track is formed at least partially by an axially formed sheet-metal portion having a free edge;
- and
- the free edge faces away from the pendulum mass, wherein;
- the axially formed sheet-metal portion comprises an area curved by sheet-metal forming;
- and
- a portion of the roller body rolls on the area curved by sheet-metal forming.
