Definitions
- the invention relates to a device for transmitting torque.
- the invention relates to a torque transmission device for use in a drive train in a motor vehicle.
- a device for transmitting torque between a drive motor and a transmission is provided.
- the device optionally includes a clutch and one or more devices for decoupling or eradicating rotational irregularities in the drive train.
- These rotational irregularities may be caused in particular by the drive motor, which may comprise an internal combustion engine, in particular a piston engine.
- non-uniformities in the transmitted rotary motion may also be coupled in the opposite direction, for example via a drive wheel coupled to the transmission.
- a combination of an elastic element and a centrifugal pendulum often results in a variety of components that are not arranged space saving in all cases. It is therefore an object of the present invention to provide an improved means for transmitting torque using a centrifugal pendulum and an elastic member.
- the invention solves this problem by means of a device having the features of the independent claim. Subclaims give preferred embodiments again.
- An inventive device for transmitting torque comprises a
- Input side which is arranged rotatably about a rotation axis, a centrifugal pendulum with two axially offset pendulum flanges and a lying between the pendulum flanges, in the Rotary sliding pendulum mass, also an elastic element for torsionally elastic connection of the input side with the centrifugal pendulum and an output side, which is connected to the pendulum flanges.
- the pendulum mass and the elastic element are arranged axially offset radially outward.
- the arrangement of the elastic element and the pendulum masses radially outward a space advantage over a known device for transmitting torque can result.
- a number of used devices of the device can be reduced. This can result in cost advantages in the production.
- the input side comprises a clutch basket with a
- the pendulum mass can also be arranged radially outside the clutch basket or in such a way that it lies at least partially radially outside the clutch basket. The exact radial position of the pendulum mass may depend on its current deflection relative to the pendulum flanges.
- the pendulum flanges are connected radially within the pendulum mass torque-locking together and the elastic element engages radially outward in the first pendulum.
- a torque which transmits the elastic element can be coupled into the centrifugal pendulum in a simple and efficient manner.
- An intermediate flange or a complex linkage for transmitting the required forces can be omitted.
- pendulum flanges are radially inward of the pendulum mass
- the output side of a turbine of a hydrodynamic torque converter include.
- the non-positive connection of an element of the output side on a large radius about the axis of rotation can help to keep the transmitted forces low and save particularly complex or high-mass transmission elements.
- connection between the elastic element and the first pendulum flange, which faces the elastic element can be carried out in different variants.
- an engagement element for engagement with the elastic element is formed integrally with the first pendulum flange.
- a tab can be issued or bent out of the first pendulum flange in the axial direction.
- an engagement element for attachment to the elastic element is attached to the first pendulum flange.
- the engagement member may include a tab or a hook which is frictionally connected to the first pendulum. This can be avoided that the cross section of the first pendulum is greatly reduced.
- a radially outer portion of the first pendulum flange extends in the axial direction to form a radially outer abutment for the elastic element.
- the elastic element can be pressed against the system, which ensures a correct position of the elastic element.
- a desired damping of the spring movement of the elastic element can be achieved by the resulting friction.
- the pendulum flanges in particular the first pendulum flange facing the pendulum mass, are shaped such that the pendulum mass and the elastic element are insulated from each other so that physical contact between the pendulum mass and the elastic element is prevented.
- the first pendulum flange can in particular be located axially between the pendulum mass and the elastic element. A movement of the pendulum mass can thereby be improved regardless of a movement or compression of the elastic element.
