-one for affecting damping and/or the biased device of the natural frequency of centrifugal force pendulum adaptedly, wherein,
This damping and/or biased device act at least one in described pendulum mass.
Torshional vibration damper proposed here comprises the centrifugal force pendulum that has multiple pendulum mass, as basic known by prior art.At this, multiple, usual four pendulum masses are fixed on a rotatable dish, and this dish is called rotatable load bearing unit here, and wherein, these pendulum masses have free movement space.Common Transformation Protocol is, pendulum mass is suspended on rotatable load bearing unit on bearing pin, and wherein, the receiving hole of pendulum mass is bending elongated hole, and pendulum mass can be moved along this elongated hole on bearing pin.At this, design pendulum mass and elongated hole like this, make pendulum mass implement vibration damping vibration when predetermined frequency, compensate natural vibration thus.In order to by the function of centrifugal force pendulum from a predetermined frequency expansion to multiple frequency, here proposing, using one for affecting damping and/or the biased device of the natural frequency of centrifugal force pendulum adaptedly.This damping and/or biased device be such as:
-for the pressure chamber of fluid, this pressure chamber produces with at least one pendulum mass at least in part and contacts, and wherein, the pressure in pressure chamber is change;
-magnetic field; And/or
-electrostatic force.
Described device produces damping and/or bias voltage at least one in described pendulum mass, and natural frequency is changed due to this damping and/or bias voltage.This damping and/or bias voltage such as can be produced by magnetic field, and this magnetic field is change.Also can be that this damping and/or bias voltage are produced by electrostatic force.Particularly preferably use adaptive damper.The damper of this adaptation by adjustment resisting medium, such as hydrodynamic pressure or can be changed by the bias voltage changing damper.Particularly preferably, the pressure chamber by arranging at centrifugal force pendulum place produces the direct transmission at least one in described pendulum mass.This pressure chamber is such as a part for the moist chamber of wet friction clutch, and wherein, the fluid of described pressure chamber is then the cooling liquid of friction clutch.
In the configuration with pressure chamber, the pressure of the fluid in pressure chamber can be changed.Especially pressure can be changed by the pump of the forced convection for cooling liquid usually existed when pressure chamber is load cavity enforcement.Therefore realized the bias voltage of at least one in the pendulum mass of described centrifugal force pendulum or damping by this device, thus.The natural frequency of centrifugal force pendulum is change.Therefore especially can some other frequencies of damping effectively.Particularly preferably, produce vibration by the pump for fluid, this vibration is passed at least one pendulum mass described.
According to another Advantageous embodiments of described torshional vibration damper, described damping and/or biased device are a pressure chamber and described pressure changes due to the angular velocity of load bearing unit.
In this preferred implementation, liquid is outwards accelerated according to the rotational speed of load bearing unit, and thus, the pressure in pressure chamber increases along with angular velocity.Its effect is, natural frequency be low when the angular velocity of load bearing unit is low and angular velocity height at load bearing unit time improve.This just in time describes this characteristic: such as there is low frequency when starting in a motor vehicle when having these characteristics and at full loading operation time there is relatively high frequency.This point can realize especially effectively, if described pressure chamber is a part for the moist chamber of friction clutch.
According to another Advantageous embodiments of described torshional vibration damper, described damping and/or biased device are a pressure chamber and described pressure imports owing to increasing liquid and/or reduces liquid to derive and change.
According to this Advantageous embodiments, pressure was changed by (additionally), and its mode is, being directed through pump to increase and/or being reduced by expulsion valve of liquid.If described pressure chamber forms a part for moist chamber, make the pump for cooling liquid forced convection can by together for this object, this mode of execution be also particularly advantageous.
According to another Advantageous embodiments of described torshional vibration damper, described damping and/or biased device are a pressure chamber and described liquid flows on the inner side of at least one pendulum mass described.
The advantage of this configuration is, the change of described pressure by least one pendulum mass described preferably in one direction, namely to external pressure.This effect especially can be strengthened thus: derived by liquid in the side of such pendulum mass, makes the fluid pressure on outside pendulum mass little especially, and Pressure Drop occurs and large especially in pendulum mass.If the pressure in pressure chamber changes due to the angular velocity of load bearing unit, this configuration is particularly advantageous.(normally bending inside this) is then collided on the inner side of pendulum mass and the bias voltage be therefore responsible for pendulum mass by the liquid that radially outward accelerates.
According to another aspect of the present invention, also propose a kind of friction clutch, for the connection of throwing off of output shaft and power train, this friction clutch at least has following parts:
-at least one friction plate group, can transmitting torque in impaction state by it;

Described torshional vibration damper to be arranged in above-mentioned friction clutch and to realize the compensation to different natural frequencies, and this natural frequency may cause the vibration of friction clutch and/or power train or Motor Vehicle.For this friction clutch advantageously, the quantity of torshional vibration damper or centrifugal force pendulum can be reduced or expand and by the frequency spectrum of the natural frequency of vibration damping, and can need not strengthen or obviously strengthen friction clutch compared with known friction clutch.
According to another Advantageous embodiments of described friction clutch, this friction clutch wet type ground forms and has moist chamber.
Particularly advantageously above-mentioned torshional vibration damper is used, because this torshional vibration damper and the quality can compared with the known centrifugal force pendulum of prior art with reduction when friction clutch is implemented like this.By proposed torshional vibration damper, especially can compensate by using the moist chamber in friction clutch the efficiency reduced owing to increasing (motion) quality along with cooling liquid here.
According to another Advantageous embodiments of described friction clutch, described damping and/or biased device are a pressure chamber and described moist chamber comprises described pressure chamber.
In this particularly advantageous mode of execution of friction clutch, the change function of damping frequency and the use of moist chamber can be combined mutually, reduce the additional installing space needed thus, or even can save installing space.Especially, it is the effective especially method of operation of the friction clutch with this torshional vibration damper that the pressure in pressure chamber changes with centrifugal force relatively due to the angular velocity of the rotary component in friction clutch.
According to another Advantageous embodiments of described friction clutch, in moist chamber relative to pressure chamber radially-inwardly stagger at least one in described pendulum mass region at least one liquid outlet is set, the change of the pressure in moist chamber is mainly acted on the inner side of involved pendulum mass.
Can be realized by this particularly advantageous configuration of friction clutch, at least one pendulum mass described from inside to outside produces Pressure Drop.This is especially favourable for a kind of enforcement, and in this enforcement, the pressure in pressure chamber will control according to angular velocity, because collide on centrifugal direction at least one pendulum mass described at this accelerated liquid.This effect can be derived in lateral outer by liquid and be supported in pendulum mass.Increase the Pressure Drop in pendulum mass thus.
