Definitions
- the present invention relates to a damper and a transmission with such a damper, in particular for damping torsional vibrations in a drive train of a vehicle.
- Hybrid vehicles can have a transmission with a vibration decoupling system, which is used in particular to dampen vibrations in the drive train between an internal combustion engine and an electric drive machine.
- a decoupling system includes, for example, a two-mass flywheel (DMF), a damper and a torsion damper, a so-called “KO clutch” for decoupling the internal combustion engine from the electrical drive machine.
- a bearing shield in the gearbox can be used to separate the DMF and the damper into dry and wet operating areas. For example, the DMF is in the dry and the damper in the wet installation space.
- the damper In the case of hybrid drive trains, the damper is therefore not located in the torque converter, for example, compared to vehicles driven by combustion engines, but directly in a housing of the transmission.
- Flyweights / damper masses of Til gers to dampen torsional vibrations in the drive train dip, for example, with a fluid in the transmission, which is used for cooling and / or lubrication.
- the fluid is, for example, gear oil.
- immersion and removal of the flyweights can lead to the transmission oil being thrown up and / or foamed.
- the transmission oil In the “foamed” state, for example, the transmission oil can flow so slowly back into a sump of the transmission that it is not available in sufficient quantities to supply the transmission components.
- centrifugal pendulum device for damping or eliminating torsional vibrations with pendulum masses distributed over a circumference.
- the centrifugal pendulum device is characterized in that it comprises a lateral protective wall which is fastened to a burst protection ring and with a fastening of a pendulum mass carrier / absorber mass carrier for receiving the pendulum masses.
- the protective wall serves as a privacy screen and as protection against the penetration of foreign bodies into the centrifugal pendulum device.
- Attachment of the protective wall requires a modification of the fastening of the pendulum mass carrier, whereby a mechanical load-bearing capacity of the riveted connection can be reduced.
- the cage is provided to accommodate the pendulum masses at the same time, a corresponding design of the cage is provided for receiving the pendulum masses, which results in increased technical effort in the manufacture of the cage.
- the sealing membrane is attached to a guide structure / a damper mount, which requires a modification of the guide structure and thus additional technical effort.
- the object of the present invention can therefore be seen in creating an improved concept for a damper, in particular for reducing the effects of a fluid.
- the present invention relates to a damper, for example for damping torsional vibrations in a drive train of a vehicle.
- the absorber comprises one or more absorber masses and a absorber carrier that can be coupled to the drive train for receiving the one or more absorber masses.
- the one or more damper masses are movably guided by the damper carrier in order to at least partially dampen the torsional vibrations.
- the damper comprises a balancing plate provided for balancing the damper, which is coupled non-rotatably to the damper carrier, and a displacement element.
- the displacement element surrounds the one or more damper masses at least partially in order to at least reduce an advance of a fluid which at least partially surrounds the damper to the one or more damper masses, the displacement element being attached to the balancing plate.
- the damper can be used in particular in a vehicle transmission for vibration decoupling. For example, an at least partial vibration decoupling between an internal combustion engine and an electric drive machine in a transmission of a hybrid vehicle can be achieved by means of the absorber.
- the absorber carrier is, for example, coupled to the drive train in a rotationally test manner and comprises for receiving the absorber masses, for example, one or more bolts, each of which can pass through one of the absorber masses in an axial direction and thereby secure it in a radial direction.
- the damper masses can be accommodated in such a way that they are movably guided in the radial direction, for example, with a play of movement.
- Torsional vibrations within the drive train can thus be eliminated or at least dampened by shifting the damper masses.
- the damper masses can protrude in the radial direction, for example, into a trough for storing the fluid.
- the tub is filled with the fluid, for example up to a Fluidpe gel.
- the absorber carrier comprises, for example, one or two flange parts for securing in the axial direction, which are made of hardened steel in order, for example, to withstand mechanical loads at a maximum speed of the absorber.
- the balancing plate can be designed in such a way that an imbalance of the absorber is at least reduced by a suitable mass distribution of the balancing plate and / or by centering the balancing plate.
- the balancing plate can be individually adapted to the damper and its imbalance to reduce the imbalance. For a reduced technical effort for adapting the balancing plate, this can, for example, in contrast to the damper carrier, be made at least partially from un hardened steel. As a result, the balancing plate can be drilled and welded more easily for adaptation compared to hardened steel.
- the displacement element surrounds the damper masses, for example, in such a way that a flow of the fluid towards the damper masses is reduced.
- the displacement element can serve as a splash guard against the fluid.
- the displacement element projects beyond the damper masses, for example in the radial direction, so that it is at least partially immersed in the fluid in order to at least partially shield the damper masses from the fluid and thereby reduce the penetration of the fluid to the damper masses.
- the fluid is, for example, a coolant and / or a lubricant.
- the fluid is, for example, a transmission oil, which is used on the one hand for lubrication and on the other hand for cooling components.
- the displacement element is, for example, non-rotatably connected to the balancing plate, so that it can rotate partially below the fluid level in the fluid when the damper is operated.
- the displacement element can have a smooth or “closed” surface contour at least in an area which is below the fluid level.
- the damper also includes a hub that can be coupled to the drive train, the balancing plate and the damper carrier being connected to the hub in a rotationally fixed manner.
- the hub is, for example, non-rotatably connected to the drive train.
- the hub has, for example, an internal toothing which engages in a form-fitting manner with an external toothing of a shaft of the drive train.
- the balancing plate and the absorber carrier can, for example, each be coupled to the hub in a rotationally test manner by one or more riveted connections.
- the balancing plate and the damper carrier can be coupled to the hub in a rotating test by means of one or more common Nietver connections.
- a connection of the balancing plate and the damper carrier to the drive train via the hub can be technically easier to implement than a direct, non-rotatable connection of the damper carrier and the balancing plate to the shaft, since, for example, there is no toothing with the balancing plate and the damper carrier and / or no hardening this is required.
- the displacement element surrounds the damper masses at least partially radially and axially.
- the displacement element has a U-shaped profile that at least partially radially and axially surrounds the Tilgermas sen.
- the U-shaped profile can be understood as a so-called “U-profile” or as a profile that is open in one direction.
- the damper masses and the displacement element are arranged, for example, in such a way that the damper masses protrude at least partially into the U-shaped profile in the radial direction.
- the damper masses can be surrounded at least partially in the ra-media direction and in the axial direction by the U-shaped profile. In this way, penetration of the fluid from the axial and radial directions can be reduced.
- the displacement element is arranged in such a way that the U-shaped profile of the displacement element displaces the fluid from a deflection area of the damper masses.
- the damper masses can be moved in a radial direction within a deflection range.
- the displacement element can also be arranged in such a way that the damper masses are spaced apart from the displacement element in the radial direction during deflections within the deflection area.
- the deflection area can be understood as an area in which the absorber masses can move when the absorber rotates and the absorber masses deflect.
- a distance between the displacement element and the deflection area of the absorber masses can prevent the absorber masses from striking and / or rubbing against the displacement element.
- the distance in the radial direction can optionally be chosen so that fluid that penetrates through leaks or through the hub to the damper masses and collects within the displacement element is conveyed out of the displacement element by the rotation of the Til germassen.
- the displacement element is fastened to the balancing plate with at least one riveted connection.
- the rivet connection has the advantage over other options for connecting the displacement element to the balancing plate, for example, that the rivet connection can be released for maintenance and / or repair purposes, for example.
- the displacement element is fastened to the balancing plate with at least one material connection.
- the material connection can be produced, for example, by welding or by soldering.
- An integral connection of the balancing plate and the displacement element is particularly advantageous and technically feasible if the balancing plate and the displacement element are made of unhardened steel, at least in the area of the integral connection.
- the balancing plate is designed to hold one or more balancing masses.
- the balancing plate includes, for example, corresponding pockets or receptacles for receiving the balancing masses.
- the balancing plate can in particular also be designed to accommodate the balancing masses in that it is manufactured at least partially from unhardened or other steel or material which is suitable for a welding or soldering process. In this case, the balancing masses can be welded to the balancing plate.
- the balancing masses can thus be attached to the balancing plate, for example, by means of an automated welding process.
- the displacement element comprises an opening for separating fluid which has penetrated to the one or more damper masses.
- the fluid can, for example, penetrate the damper masses via leaks or further openings in the displacement element. In some cases, the advance of the fluid for the purpose of supplying other components with the fluid may be desired. This fluid can separate the fluid again via the opening in order to avoid or reduce dragging moments and “foaming” or foaming of the fluid by the damper masses.
- the displacement element is designed in one piece as an edged workpiece.
- the technical effort involved in manufacturing the displacement element can be reduced, since, for example, it is not necessary to join several components together.
- the displacement element can have a higher mechanical load-bearing capacity than a displacement element with several components joined together.
- the present invention relates to a transmission for a drive train of a vehicle.
- the transmission comprises a housing with a trough for storing a fluid provided for cooling and / or lubrication and a damper that can be coupled to the drive train for damping torsional vibrations.
- the damper is at least partially net angeord in the tub.
- the damper is designed according to one of the exemplary embodiments described above, in order to at least reduce a forward movement of the fluid to one or more rotatably arranged damper masses of the damper.
- FIG. 2a shows a first embodiment of a damper with a Verdrängerele element
- Fig. 2b shows a second embodiment of the damper.
- Vehicle transmissions can be partially filled with a fluid provided for cooling and / or lubrication.
- the fluid is, for example, transmission oil, which can act on the one hand as a lubricant and on the other hand as a coolant for the transmission.
- the demand for transmission oil can be so high that components of the transmission are at least partially below a fluid level of the transmission oil located in the transmission.
- a damper for damping torsional vibrations can be partially immersed in the transmission oil.
- absorber masses that are attached to the absorber over the circumference of the absorber are immersed and removed, causing the transmission oil to slip and foam.
- Foamed transmission oil can flow back insufficiently slowly into a pan or sump provided for storing the transmission oil, so that at times not enough transmission oil may be available to supply components in the transmission.
- FIG. 1 shows part of a conventional transmission 100, as it can be used, for example, in a (hybrid) vehicle.
- the transmission 100 comprises a (speed-adaptive) damper 110, a fluid 120 located in the transmission 110, a two-mass flywheel 130, a torsional vibration damper 140 and a separating clutch 150 tion motor (not shown) may be provided by an electric drive machine (not shown).
- the fluid 120 is, for example, transmission oil, which is used to cool and lubricate components of the transmission 100.
- a fluid level 122 of the transmission oil 120 can be so high that the absorber 110 is partially immersed in the transmission oil in a radial direction.
- the damper masses 112 are arranged in an axial direction between flange parts 114 egg nes damper carrier.
- the damper masses 112 are arranged to be movable, for example, so that they can contribute to damping torsional or torsional vibrations through displacements, in particular in the radial direction.
- the absorber masses 112 can foam up the transmission oil so that it can flow back so slowly into a sump 124 of the transmission 100 and is therefore temporarily not available for cooling and / or lubrication. This can therefore lead to inadequate cooling and / or lubrication of further components of the transmission 100.
- Fig. 2a shows a first embodiment of a damper 210, which is designed to reduce the penetration of a fluid to a damper mass 212 of the damper 210 at least least.
- FIG. 2a shows a rear view (left), a sectional image (center) and a front view (right) of the first exemplary embodiment.
- the damper mass 212 is arranged in an axial direction between flange parts of a Til ger strictlys 214.
- the flange parts 214 can in turn be equipped with bolts 216, which pass through openings 219 of the Til germasse 216 in the axial direction to accommodate the damper mass 216.
- the openings 219 are designed in such a way that the damper mass 212 is guided between the flange parts 214 such that it can move in the radial direction and in the circumferential direction within a deflection region.
- the damper mass 212 can bring about changes in a moment of inertia of the damper 210, which lead to the damping or absorption of torsional vibrations that originate from a drive train (not shown) coupled to the damper 210.
- the damper 210 comprises a balancing plate 215 provided for balancing / balancing the damper 210, which, together with the damper carrier, is rotatably coupled to a hub 218 by a rivet connection 217.
- the hub 218 is also coupled to the drive train via a toothing with a shaft (not shown).
- the balancing plate 215 and the absorber carrier can be coupled separately and, in some exemplary embodiments, also directly, that is to say without an intermediate hub, to the drive train or to the shaft of the drive train.
- the balancing plate 215 has a plurality of balancing recesses 224, which are introduced into the balancing plate 215, for example, to set a mass distribution of the balancing plate 215 in order to reduce or eliminate an imbalance in the absorber 210 (“balancing”).
- the damper 210 comprises a displacement element 211 which at least partially surrounds the damper mass 212 in order to at least reduce the penetration of a fluid at least partially surrounding the damper 210 to that of the damper mass 212.
- the displacement element 211 overlaps the balancing plate 215 in the radial direction and is fastened to the balancing plate 215 in the region of a radial overlap by a rivet connection 213.
- the riveted connection 213 comprises, as can be seen in the rear view of the absorber 210, several rivets.
- connection of the displacement element 211 to the damper 210 via the balancing plate 215 can be advantageous, for example, compared to a connection via one or both of the flange parts 214, since this does not require any modification of the damper carrier or its connection to the drive train.
- the balancing plate 215 is made of an unhardened steel / material, which means that the connection of the displacement element 211 via the balancing plate 215 may require less technical effort than the connection of the displacement element 211 via the flange parts 214 or the damper carrier .
- it can be technically less complex to drill holes for the riveted connection 213 into the balancing plate 215 than into the absorber carrier 214.
- the displacement element 211 is designed in such a way that it at least partially surrounds the damper mass 212 radially and axially. As the first embodiment shows, In particular, the displacement element 211 completely covers / surrounds the damper mass 212 in the radial direction and at least partially in the axial direction from both sides.
- the displacement element 211 has a U-shaped profile, also called a “U-profile”.
- the damper mass 212 is net angeord to the displacement element 211, so that the damper mass 212 partially protrudes into the U-profile.
- the transmission oil can be displaced from the deflection area or movement area of the damper mass 212 and, as a result, penetration of the transmission oil to the damper mass 212 can be at least reduced compared to a damper without such a displacement element 211.
- the displacement element 211 can reduce an amount of transmission oil that can penetrate to the damper mass 212 due to transmission oil splashing around.
- the displacement element 211 can be designed, for example, as a one-piece folded workpiece. As a result, costly and time-consuming joining processes can be avoided when manufacturing the displacement element.
- the displacer element 211 is also designed and arranged, for example, so that the damper mass 212 has a (safety) distance from the displacer element 211 in the radial direction, particularly with maximum deflections in the radial direction. As a result, wear and any damage that result from collisions between the displacement element 211 and the damper mass 212 can be avoided.
- the displacement element 211 is connected to the balancing plate 215 on one side, that is to say on one axial side of the damper mass 212, in order, for example, to reduce the installation effort compared to a connection of the displacement element 211 on both sides.
- the displacement element 211 extends so far inwardly in the radia len direction that an opening 221 is formed radially inside the displacement element 211, via which transmission oil, which to the damper mass 212 has penetrated, can be conveyed away by the damper mass 212.
- the damper mass 212 can convey away the transmission oil through the opening 221 by rotation.
- FIG. 2b shows a second exemplary embodiment of the absorber 210.
- FIG. 2b shows a rear view (left), a sectional image (center) and a front view (right) of the second exemplary embodiment.
- the displacement element 211 does not overlap with the balancing plate 215 in the radial direction, but is arranged flush in the radial direction or "abutted" with the balancing plate 215 and with a material connection 213 'associated with this.
- the integral connection 213 ‘is, for example, a welded connection in the form of a so-called" weld seam ".
- the welded connection 213 ' can be produced in an automated and mechanical manner.
- the flange parts 214 are, as is customary in practice, for example made of hardened steel. It is clear to a person skilled in the art that a welded connection between the damper carrier / flange parts 214 and the displacement element would therefore be technically more complex to produce than welded connection 213 '. Due to the connection shown in Fig. 2b to the displacement element 211, costs in the manufacture of the absorber 211 can therefore be saved, for example.
- the balancing plate 215 has several recesses 222, which can serve to improve the removal of the transmission oil in the same way as the opening 221 for removal / separation of the transmission oil.
- the balancing plate 215 has a balancing mass 223, which is welded to the balancing plate 215, for example.
- the damper 210 described above can, for example, analogously to the Til ger 110 in a transmission for a drive train of a vehicle used in which the damper 210 protrudes into a tub which is filled with transmission oil.
