Definitions
- the invention relates to a torque transmission device with a rotatably arranged about an axis of rotation, at least partially filled with fluid housing and a centrifugal pendulum device with at least two centrifugal pendulums arranged in the housing, each with a set distributed over the circumference arranged Pen- masses, which rotate in the centrifugal force field around the axis of rotation Torque transmission device along predetermined pendulum tracks are arranged displaceably.
- Torque transmission devices for example friction clutches, double clutches, hydrodynamic torque converters and the like, serve in particular in drive trains of motor vehicles for the controlled transmission of torque, for example from an internal combustion engine to a subsequent drive train device, for example a transmission. Due to the adhesion of the internal combustion engine with torsional vibrations in the torque to be transmitted, generic torque transmission devices have means for torsional vibration isolation. The torque transmission device can take place in a fluidic environment.
- the torque transmission device has an at least partially filled housing with a fluid, for example oil, water, pressure medium or the like, in which the functional elements for torque transmission, for example one or more wet-operated friction clutches or a torque converter with pump and turbine wheel and the stator and, if appropriate, lockup clutch are accommodated.
- the functional elements such as centrifugal pendulum and, if necessary, torsional vibration Dampers for torsional vibration isolation are also designed for fluidic operation.
- DE 10 2014 217 472 A1 discloses a damper system effective as a torque transmission device, in which two centrifugal pendulums are arranged radially above each other in a housing filled with fluid, each containing a set of pendulum masses distributed over the circumference.
- the pendulum masses of the radially outer centrifugal pendulum pendulum are arranged on a support member, wherein axially opposite pendulum masses are connected to pendulum mass units and between the support member and the pendulum mass units each two pendulum bearings are provided which specify a given pendulum track of pendulum mass units and the support member.
- the radially inner centrifugal pendulum contains a carrier part formed from two axially spaced-apart side parts, between which the pendulum masses are arranged.
- the self-aligning bearings are in this case formed between in each case a pendulum mass and the side parts.
- Publication DE 10 2013 225 023 A1 discloses a vibration isolation device which is effective as a torque transmission device and in which two centrifugal force pendulums are arranged axially next to one another. In both prior art torque transmitting devices, the two centrifugal pendulums interact with each other through fluid coupling.
- the object of the invention is the development of a Drehmomentübertragungseinrich- device.
- a torque transmission device with at least two centrifugal force pendulums is to be proposed, which can be operated substantially without interference in a fluidic environment.
- the object is solved by the subject matter of claim 1.
- the dependent claims of this give advantageous embodiments of the subject matter of claim 1 again.
- the proposed torque transmission device is used to transmit torque and the torsional vibration isolation.
- at least two centrifugal pendulums which can be tuned to different Tilger kannen, at least one torsional vibration damper and / or at least one tuned to a fixed Tilgerfrequency torsional vibration damper of the torsional vibration isolation serve.
- the torque transmission can be effected, for example, by means of one or more friction clutches combined, for example, into a double clutch, a hydrodynamic torque converter, optionally in combination with a torque converter lockup clutch or the like.
- the torque transmission device arranged around an axis of rotation for example a crankshaft axis of the internal combustion engine, a transmission axis or the like, optionally with a compensation of an axial offset, is operated wet or moist.
- the said functional elements are operated for torsional vibration isolation and / or torque transmission in the housing by means of an at least partially and optionally depending on the operating state existing fluid or this at least exposed.
- the fluid may be oil such as transmission oil, pressurized fluid, for example ATF (automatic transmission fluid), brake fluid, water, a mist or the like.
- the at least two centrifugal pendulum pendulums each have a set of pendulum masses distributed over the circumference, which on a support part travel along a predetermined pendulum track in the centrifugal force field of the rotary shaft rotating about the axis of rotation.
- torque transmission device with a rotatably arranged around an axis of rotation, at least partially filled with fluid housing and at least two distributed in the housing over the circumference arranged sentences of the pendulum masses which arranged displaceable in the centrifugal force field of rotating about the axis of rotation Drehmomentübertragungseinrich- along predetermined pendulum paths are.
- the displaceable uptake of the pendulum masses on the support part preferably takes place by means of two pendulum bearings spaced apart in the circumferential direction.
- Each of the self-aligning bearings is formed by complementary raceways formed in the pendulum masses and in the carrier part on which a rolling element, for example a pendulum roller, rolls.
- a fluid effective release agent is provided as a mechanical barrier for the fluid between two sets of pendulum masses.
- the separating means can extend over the entire circumference of a plane of pendulum masses or can be provided only over partial circumference of a pendulum mass optionally including its pendulum movement over the given oscillation angle.
- the release agent may be formed of metal or plastic.
- sheet metal is not exclusively used for the material metal. Rather, the term sheet metal can be understood to mean the purely technical form. Thus, correspondingly provided plastic parts with a small thickness to the other dimensions can be understood as sheets such as plastic sheets.
- the Positioning of metal sheets is preferably carried out by punching and optionally forming method. The production of release agents from plastic takes place in a preferred manner by injection molding.
- At least two sets of pendulum masses are arranged radially one above the other.
- the separating means is arranged radially between the two sets.
- two sets of pendulum masses can be arranged axially next to one another.
- the separating means is arranged axially between the pendulum masses.
- the release agent is formed between these or a fluid flow possibly occurring between them in order to avoid a fluidic disturbance of the sets.
- At least two sets of pendulum masses can be accommodated on a single carrier part by means of self-aligning bearings along pendulum tracks.
- the carrier part designed, for example, as a flat or potted sheet-metal part can in this case accommodate pendulum masses of both sets on different diameters on both sides, wherein axially opposite pendulum masses are connected to pendulum mass units by means of connecting means.
- the connecting means for example spacer bolts, spacer plates or the like, pass through corresponding recesses in the flange part.
- the release agent is in this case added radially between the two sets pendulum masses on axially adjacent foreign components such as a torsional vibration damper or the like or in a preferred manner on the support member.
- the release agent directly on the Fixed support part.
- axially extending separating plates can be provided on both sides of the carrier part radially between the pendulum masses.
- These dividers can be positively connected to the carrier part, for example, riveted, latched or inserted or inserted as molded dividers.
- dividing plates of similar material as the carrier part can be connected in a materially bonded manner, such as, for example, welded.
- a riveting against the support member may comprise a two-sided attachment axially opposing dividers by means of this sweeping rivet.
- the separating plates can have an L-shaped cross section with an axial leg for repelling fluid and a radial leg for attachment to the carrier part.
- axially opposite separating plates can be connected to one another.
- the carrier part has recesses which pass through at least one separating plate, wherein an axially fixed connection is formed between the dividing plates themselves.
- both separating plates can pass through the recesses and be locked together.
- one separating plate can pass through a recess and be latched with the other, axially opposite separating plate or be connected bayonet-like.
- At least one set of pendulum masses can be arranged between two lateral parts forming an axial receiving region for the pendulum masses.
- the side parts and one pendulum mass each form the self-aligning bearings.
- the separating means can be arranged axially between the side parts. For example, in axially opposite Overlying recesses separating plates can be inserted completely or by means of axially extended pin.
