Definitions
- the invention relates to a torque transmission device, in particular in a drive train of a motor vehicle with two mutually limited by a common axis of rotation rotatable disc parts and at least two each radially on the one disk part about a parallel to the rotation axis parallel oscillating axis rotatably arranged and driven by the other disk part by means of a toothed pendulum masses ,
- Torque transmission devices serve to transmit torques from a drive unit such as an internal combustion engine to an output component, for example a transmission.
- a drive unit such as an internal combustion engine
- an output component for example a transmission.
- piston lifting machines such as diesel engines occur due to the torque pulses produced discontinuously in the individual combustion cylinders torsional vibrations on the crankshaft of the internal combustion engine, as known for a long time from the prior art by means of torsional vibration damper as dual mass flywheels, disc dampers in clutch discs and the like trained torque transmission devices are damped. Due to the enormous increases in the nominal torques of the internal combustion engine over time, ever increasing demands are placed on the insulating effect of the torque transmission devices.
- the object of the invention is the advantageous development of a torque transmission device without additional parts and costs, in particular for reducing or eliminating the noise.
- the object is rotatably arranged by a torque transfer device, in particular in a drive train of a motor vehicle with two mutually limited by a common axis of rotation rotatable disc parts and at least two radially on the disk part about a parallel to the rotation axis parallel pivot axis and driven by the other disc part by means of a toothing Pendulum masses solved, wherein at least two pendulum masses are clamped under centrifugal force in the circumferential direction against the other disc part.
- a torque transfer device in particular in a drive train of a motor vehicle with two mutually limited by a common axis of rotation rotatable disc parts and at least two radially on the disk part about a parallel to the rotation axis parallel pivot axis and driven by the other disc part by means of a toothing Pendulum masses solved, wherein at least two pendulum masses are clamped under centrifugal force in the circumferential direction against the other disc part.
- the preload of the teeth is achieved at idle by an exact alignment of at least one pendulum mass along a trained upon rotation of the torque transmitting device around the axis of rotation centrifugal Force field is prevented by means of a corresponding pitch of the toothing.
- the pendulum masses are arranged symmetrically with respect to the fulcrum. It may be sufficient to prevent noise, for example, to provide two diametrically opposed pendulum masses of a larger number, for example, four circumferentially arranged pendulum masses by means of a bias.
- a bias formed pitch of the teeth For the sake of training common parts and all pendulum masses can be provided with the same, a bias formed pitch of the teeth.
- the arrangement of the pitches of the teeth takes place at diametrically opposite pendulum masses in such a way that their focal points formed in opposite directions of rotation with respect to their centrifugal axis and thus form an opposing torque, so that the pendulum masses mutually brace under centrifugal force on the teeth. It is understood that with correspondingly finely formed toothing and / or desired large deflection of the centers of gravity of the pendulum masses against over the centrifugal force direction a toothing part of the corresponding pendulum mass can be displaced by several teeth with respect to an aligned arrangement of the center of gravity.
- a spring device acting as a torsional vibration damper optionally in conjunction with a friction device, comprising at least one spring accumulator acting in the circumferential direction.
- the spring device can serve as a barrier for the pendulum masses for biasing the toothing.
- the pendulum masses rotatably received on a disk part and driven by the other disk part can be driven in various kinematic ways encompassed by the inventive concept.
- the toothing can be connected by means of a to the other disc part ordered external teeth and be formed on the pendulum mass radially inwardly directed external teeth.
- the center of gravity of the pendulum masses is preferably received radially outside of the pendulum axis of rotation.
- the pendulum rotation axis is firmly formed on the one disc part, for example by means of a bolt.
- the toothing can be formed by means of an inner toothing arranged on the other disk part, for example a preferably primary flywheel mass, and outer toothings oriented outwards on the pendulum masses.
- the force acting in the centrifugal force direction is absorbed by the toothing, so that the arranged on the other disc part, for example, on a flange of a secondary flywheel pendulum rotational axis only has to apply the rotary drive.
- the pendulum pivot axis of the pendulum mass is provided at a rotation of the two disc parts radially displaceable along the centrifugal force direction.
- bolt or sliding block which moves radially in a centrifugal force extending slot at a successful under load rotation of the disc parts against each other.
- bolt or sliding block can be arranged firmly with the other disc part and the slot in the pendulum mass.
- the bolt or sliding block can be firmly held in all or individual pendulum masses and the corresponding slots can be provided in the other disk part, for example in the flange part of a flywheel fixedly connected to a flywheel mass.

- the pendulum masses 9 are rotatable about the pendulum axis 21 on the disc part 5, which is for example driven by a crankshaft of an internal combustion engine, and are rotatably connected by the disc part 6, which is optionally connected to a driven component, such as a transmission input shaft of a transmission with the interposition of a friction clutch or is connectable, rotationally driven.
- This rotary drive takes place at a rotation of the two disc parts 5, 6 against each other by means of the toothing 11 formed from the external teeth 12, the pendulum mass 9 and the external teeth 13 of the disc part 6.
- the mass accumulation 14 arranged radially on the outside of the pendulum mass is provided, so that the center of mass 15 of the pendulum mass 9 is set radially outside its pendulum axis 21 on the pendulum axis 10. If a torque is introduced into the disk part 5, for example by the internal combustion engine, and a load is held against the disk part 6, for example a driving resistance, the two disk parts rotate relative to one another. As a result, the energy storage 4 are compressed and the pendulum masses 9 against the action of the axis of rotation 2 directed radially outward centrifugal force with respect to their center of gravity 15 moves radially inward.
- the disk part 6 is supported on the disk part 5 in the direction of rotation and transmits the introduced torque to the exhaust drive component.
- torsional vibrations are attenuated or eradicated.
- the pendulum masses 9 are braced by the centrifugal force in the toothing 11, so that noises such as clacking noise in the toothing 11 occur.
- FIG. 2 shows a partial view of the torque transmission device 1a, which is slightly modified compared to the torque transmission device 1 of FIG. 1, with an even number - here four - pendulum masses 9a, 9b distributed over the circumference.
- the pendulum masses 9a, 9b under centrifugal force against the disc part 6a clamped in the circumferential direction by at least one tooth flank 17 of the teeth 16 of the external teeth 12a against at least one tooth flank 19 of the teeth 18 of the external teeth 13a are biased against each other under centrifugal force.
- the pitch of the toothing 1a is designed so that the two diametrically opposed pendulum masses 9a are each angularly offset from each other in the circumferential direction.
- This angular displacement a, -a between the pendulum axis 10 and the centrifugal force in the form of the illustrated centrifugal force axis 20 caused under the action of centrifugal force at a rotation of the torque transmitting device 1a about the axis of rotation 2 to the pendulum masses 9a a respective oppositely directed moment, leading to a bias of the pendulum masses 9a leads in the toothing 11a.
- the opposing pendulum masses 9b are braced against each other as biased.
- the The angular offset a, -a extend over a tooth gap between teeth 18 from the tooth base to the tooth flank 19 or over a plurality of teeth 18.
- FIG. 3 shows a modification of the torque transmission device 1 a of FIG. 2.
- the pendulum masses 9 a are offset relative to the disk part 6 a with the angular offset a, -a relative to the centrifugal force axis 20 and the pendulum axis 10.
- the pendulum masses 9b are arranged in alignment with the axis of centrifugal force 20 with respect to their teeth.
- FIG. 4 shows an advantageous embodiment of the torque transmission device 1c, which is partially illustrated and similar to the torque transmission devices 1, 1a, 1b of FIGS. 1 to 3, in particular for an odd number - here three - pendulum masses 9d distributed over the circumference.
- the pendulum masses 9d in the toothing 11b are in the load-free state and not twisted disc parts 5 ( Figure 1) and 6a in the direction of rotation by the same angular offset ß between the centrifugal axis 20 and the pendulum axis 10 offset.
- the pendulum masses 9d rotate the disk parts 5 against each other against the action of the energy accumulators 4 (FIG. 1), such that the pendulum masses 9d in the toothing 11b in the circumferential direction due to the holding moment of the energy accumulator be biased.
