Embodiment
The three-dimensional side view of the centrifugal pendulum mechanism 10 according to prior art shown in Figure 1, wherein, conceals the pendulum mass pair on top in this illustration, with clear, region in the bottom is in the axial direction shown.Centrifugal pendulum mechanism 10 is arranged on the vibration damper component 12 that can rotate around spin axis 100 of a torsional vibration damper.Vibration damper component 12 has some for receiving unshowned energy storage elements such as helical spring otch 14 here in the circumferential zones of inner radial, wherein, vibration damper component 12 can be reversed relative to another vibration damper component unshowned here limitedly by the effect of these energy storage elements.
This torsional vibration damper preferably carries out vibration damping to the torsional vibration caused by internal-combustion engine.At this, torsional vibration damper can be arranged between internal-combustion engine and speed changer in Motor Vehicle drivetrain with working.
The radial extension of vibration damper component 12 forms one for receiving the pendulum mass carrier 16 of the pendulum mass 18 being arranged in pendulum mass carrier 16 both sides.At this, two pendulum masses 18 are arranged in pendulum mass carrier 16 both sides in the axial direction respectively and pass through three fixed elements 20 altogether and are interconnected to a pendulum mass pair.At this, fixed element 20 is fixedly connected with pendulum mass 18 and forms a cylindrical portion 21 in a region being axially between pendulum mass 18, this cylindrical portion is each passed through the otch 22 in pendulum mass carrier 16, wherein, otch 22 kidney shape ground is shaping like this, makes this otch allow pendulum mass 18 to move along limited pendulum raceway relative to pendulum mass carrier 16.Pendulum mass 18 can or translationally be moved towards relative to the motion of pendulum mass carrier 16, or translationally combines with the torsion of its pendulum mass center of gravity of pendulum mass opposing connection.
Pendulum raceway self is determined by the profile of the breach 26 of the complementation in the profile of the breach 24 in pendulum mass 18 and pendulum mass carrier 16, wherein, be configured to receive in the breach 24,26 of kidney shape have some rolling element 28, such as rolling bodies here especially, in order to realize pendulum mass to moving along pendulum raceway, described rolling element can roll on breach 24,26.
Fig. 2 illustrates the side view of the pendulum mass 18 of the centrifugal pendulum mechanism 10 in the special mode of execution of the present invention one.Pendulum mass 18 has the shape of arc section shape and can connect into a pendulum mass pair by three fixed elements 20 and another pendulum mass.The breach 24 of processing in pendulum mass 18 serves as the acceptance division of rolling element, can move to make pendulum mass 18 along pendulum raceway relative to pendulum mass carrier.
Pendulum mass 18 is having ratio in the section 30 of spacing to have higher density in the section 32 directly adjoining pendulum mass center of gravity 102 with pendulum mass center of gravity 102.This higher density produces thus, that is, the associated mass 36 that the section 30 with higher density is attached troops to a unit in this pendulum mass section 34 with the pendulum mass section 34 and of this directly section 32 one-piece construction of adjacent pendulum mass center of gravity 102 this section 32 adjacent by forms.At this, two peripheral side end regions that associated mass 36 adjoins pendulum mass 18 are in the circumferential arranged and are fixedly connected with pendulum mass section 34 by firmware components 20.By having the section 30 of higher density, can improve pendulum mass 18 with regard to pendulum mass 18 around pendulum mass center of gravity 102 torsion with regard to moment of inertia.
As identifiable design in Fig. 3 of the plan view of the local in the centrifugal pendulum mechanism 10 illustrated in Fig. 2 arrives, associated mass 36 and pendulum mass section 34 are partly overlapping in the axial direction in pendulum mass 18, wherein, fixed element 20 is each passed through the pendulum mass section 34 of a pendulum mass 18 and associated mass 36 and the pendulum mass 18 of arranging through the axis that this pendulum mass is right opposedly.Here unshowned, can axially be arranged between these two pendulum masses 18 for receiving the right pendulum mass carrier of this pendulum mass.
Fig. 4 illustrates the side view of the local of the pendulum mass 18 of the centrifugal pendulum mechanism 10 in another special mode of execution of the present invention.In pendulum mass 18, in the peripheral side end regions 38 of pendulum mass 18, arrange associated mass 36 like this, associated mass 36 torsionally can be received relative to pendulum mass section 34 along degrees of freedom 40.Associated mass 36 such as can torsionally be arranged on fixed element 20, such as, by being arranged on the sliding bearing on this associated mass 36.Associated mass 36 also can directly on fixed element 20 slidably, can torsionally arrange.The shape of associated mass 36 can form arbitrarily and be not limited to shown here shape.
Under a kind of state of centrifugal pendulum mechanism 10, pendulum mass carrier thus pendulum mass 18 similarly rotate around a spin axis, and in this state, centrifugal force produces such impact, associated mass 36 is made to be arranged in radially outer as far as possible, as what shown by the position 42 of associated mass.
When pendulum mass 18 is moved along pendulum raceway, associated mass 36 also can occupy the position 44 different from the position 42 being arranged in radially outer as far as possible.
The side view of the local of the pendulum mass 18 of the centrifugal pendulum mechanism 10 in another special mode of execution of the present invention shown in Figure 5.At this, the associated mass 36 be arranged in pendulum mass 18 can move along direction 46 relative to pendulum mass section 34 limitedly.For this reason, associated mass 36 has the otch 48 receiving fixed element 20, and the shape of otch 48 can determine one or more degrees of freedom of the motion of associated mass 36.As shown here, associated mass 36 tangentially can move relative to spin axis.Preferably limit the motion of associated mass 36 like this, make associated mass 36 can not exceed pendulum mass section 34 in peripheral side and stretch out.
Associated mass such as can move in end position 50 along direction 46, wherein, further motion be in the direction in which fixed element 20 on otch 48 collision restriction.Preferably, this collision can carry out vibration damping by the shock absorber part be arranged on fixed element 20 or on otch 48 or on both.
