Definitions
- the invention relates to a device for coupling two shafts arranged at a distance axially parallel or at an angle to one another with at least one coupling element.
- Devices of the generic type are known. Such devices are preferably used for engines with variable compression and / or variable displacement. In the case of such engines, the compression can be adjusted by an eccentric bearing of the crankshaft, so that there is an offset between the crankshaft and the actual output shaft of the engine. It is disadvantageous that the known systems, or the coupling elements used to bridge the axis offset, require a relatively large amount of installation space, entail high energy losses due to friction and also have no possibility of damping torsional vibrations.
- the object of the invention is therefore to provide a device of the generic type which enables an overall optimum with regard to the criteria of efficiency, compact design and damping of torsional vibrations.
- This object is achieved with a device according to the features of claim 1.
- This is characterized in that at least a first rotating mass and a second rotating mass are provided, which cooperate with at least one vibration damping element for damping torsional vibrations.
- This enables a very compact design of the device, which is also used for damping torsional vibrations. Due to the compact design, further damping elements and bearings can be dispensed with, so that energy losses caused by them can be avoided, which significantly improves the overall efficiency of the device.
- An exemplary embodiment is preferred which is characterized in that a crankshaft assigned to the first rotating mass and an output shaft assigned to the second rotating mass, in particular a transmission input shaft, have an axial offset.
- a device designed in this way can be used as a coupling unit for an internal combustion engine with variable compression.
- a coupling element according to claim 3 in particular for a device according to one of claims 1 or 2, for coupling two shafts arranged at a distance from one another parallel to the axis.
- This is characterized in that at least one elastic element is provided to compensate for the offset.
- the elastic element serves to transmit the torque and to dampen torsional vibrations.
- the at least one elastic element cyclically absorbs and releases energy.
- an exemplary embodiment of the coupling element is preferred, which is characterized in that the at least one elastic element is designed as a spiral spring, in particular as a compression spring.
- Coil springs can be used in a relatively small space needs and good efficiency absorb relatively large amounts of energy and release it again.
- An embodiment of the coupling element is particularly preferred, which is characterized in that the at least one elastic element is prestressed. This is advantageous because the pre-tensioning means that larger torques can be transmitted via the coupled shafts.
- an embodiment of the coupling element which is characterized by four disks arranged parallel to one another and coupled via the at least one elastic element. Two of the four disks are firmly connected to each other. A torque can therefore be transmitted between the two disks which are firmly connected to one another via the at least one elastic element.
- an embodiment of the coupling element is preferred, which is characterized in that the disks each have at least one opening, which is preferably elongated and is curved in the circumferential direction of the disks.
- the at least one elastic element can be inserted into the at least one opening for coupling the disks, as a result of which the space requirement can be minimized.
- Another preferred exemplary embodiment of the coupling element is characterized in that two elastic elements are assigned to the at least one opening. This enables the elastic elements to be connected in series.
- a particularly preferred exemplary embodiment of the coupling element is characterized in that two inner disks and two outer disks, which are each firmly connected to one another, are provided. Torque can thus be transmitted from the two inner disks to the two outer disks, or vice versa, via the at least one elastic element.
- Another preferred exemplary embodiment of the coupling element is characterized in that the disks connected to one another are constructed and arranged essentially symmetrically to an imaginary central plane.
- the disks connected to each other can be coupled via the at least one elastic element. Due to the symmetry, there is an advantageous flow of force so that the bearing load is as low as possible.
- Another preferred exemplary embodiment of the coupling element is characterized in that the at least one opening in the two inner disks is arranged rotated against the at least one opening in the two outer disks.
- the breakthroughs therefore only partially overlap.
- the at least one elastic element can be introduced into the partial overlap.
- an embodiment of the coupling element is preferred which is characterized in that the at least one elastic element has a bearing formed by the inner disks, in particular a spring channel and a spring stop, and a bearing formed by the outer disks, in particular a spring channel and a spring stop, interacts.
- the inner and the outer Ren discs are thus coupled together via the at least one elastic element and the bearings.
- the coupling element is characterized in that the inner disks are elastically coupled to the outer disks in such a way that they can be axially displaced with respect to one another, and in the offset, axially parallel or coaxial state from the inner to the outer disks -or vice versa - a torque is transferable. It is advantageous that in the coaxial state or with an axial displacement of any size up to a certain upper limit, torques can be transmitted via the coupling element.
- an exemplary embodiment of the coupling element is preferred that is characterized in that the inner disks and the outer disks each have an area, in particular a web and / or flange, for transmitting a torque to another component.
- the inner disks and the outer disks each have an area, in particular a web and / or flange, for transmitting a torque to another component.
- Another preferred exemplary embodiment of the coupling element is characterized in that the two rotating masses are coupled to one another via the at least one elastic element and the four disks. The two rotating masses can therefore be coupled to one another despite an axial offset.
- the at least one elastic element can be used to dampen torsional vibrations between the rotating masses.
- the object on which the invention is based is also achieved by a coupling element according to claim 16, in particular for a device according to one of claims 1 or 2, for coupling two shafts arranged at a distance from one another axially parallel or at an angle to one another, with at least one universal joint.
- the universal joint has at least one ball joint with a ball head and a ball socket. Via the universal joint with the ball joint, it is possible to arrange the two shafts at an angle to one another and at the same time to couple them particularly precisely.
- An exemplary embodiment of the coupling element is preferred, which is characterized in that the spherical head has at least one first spherical section surface and the at least one spherical socket has a mating surface adapted to it. Via the at least one spherical section surface and the adapted counter surface, it is possible to transmit a torque, in particular large torques, via the cardan joint.
- Another preferred exemplary embodiment of the coupling element is characterized in that two universal joints are provided. It is thus possible to couple the two shafts, spaced apart, axially parallel, coaxially or at an angle to one another.
- an embodiment of the coupling element which is characterized by a spherical shell with an inner ball socket and an outer ball head.
- the spherical shell thus essentially represents two ball joints lying one inside the other. These ball joints can each have a spherical section surface and one on it have adapted counter surface. The surfaces reduce the degrees of freedom of the nested ball joints to a swivel bearing.
- the swivel axes can be selected so that there is a universal joint.
- the universal joint has a fixing pin for fixing the spherical shell.
- the ball socket is additionally guided through the fixing pin, which improves the quality of the storage.
- the vibration damping element can be designed such that it absorbs and releases energy when torque is transmitted and also during one revolution, that is, it takes over a damping function.
- an exemplary embodiment of the coupling element is preferred, which is characterized in that the rotating masses are coupled to one another via the universal joint and the coupling element.
- the rotating masses can be designed for the occurring torque fluctuations in such a way that particularly good damping results.
- an embodiment of the coupling element is preferred, which is characterized in that the at least one vibration damping element in the coaxial, load-free state of the two shafts radially, under load at an angle to an imaginary diameter line and in the angled state of the two shafts during one revolution of the same passes through an angular range to an imaginary plane of rotation of one of the two shafts.
- the vibration damping element can emit and absorb energy, which results in damping of the two coupled shafts.
- an exemplary embodiment of the coupling element is preferred which is characterized in that the two rotating masses are coupled to one another via the universal joint.
- the two rotating masses can thus be axially offset or arranged at an angle to one another and coupled to one another via the universal joint. It is also possible to dampen torsional vibrations occurring between the two rotating masses via the vibration damping element.
- the object on which the invention is based is also achieved by a coupling element according to claim 25, in particular for the device according to one of claims 1 or 2, for coupling two shafts arranged at a distance parallel to one another.
- this has at least one eccentric to compensate for the offset, which is assigned to two disks and a clutch plate. Despite an axial offset, a torque can be transmitted via the eccentric between the two disks and the clutch plate.
- An exemplary embodiment of the coupling element is preferred, which is characterized in that the coupling plate is assigned to the second rotating mass, in particular via a flange.
- the coupling plate can be rotationally fixedly connected to the second rotating mass in such a way that there is a uniform rotating mass results.
- the clutch plate is part of the second rotating mass. Therefore, the clutch plate does not increase the weight of the overall arrangement.
- the coupling element which is characterized in that the two rotating masses are coupled to one another via the two disks and the clutch plate. This makes it possible to transfer a torque from one rotating mass to the other rotating mass.
- an embodiment of the coupling element is preferred, which is characterized in that the two rotating masses can be rotated relative to one another, the vibration damping element being mounted in such a way that it counteracts the relative rotation of the two rotating masses. It is thus possible for the two rotating masses to be rotatable relative to one another when a torque is applied, but the vibration damping element always absorbs energy which it can at least partially release again. In this way, torsional vibrations occurring between the two rotating masses can be damped.
- the object on which the invention is based is also achieved by a device according to claim 29.
- This is characterized by a coupling element according to one of claims 3 to 15 and / or 16 to 24 and / or 25 to 28.
- a coupling element according to one of claims 3 to 15 and / or 16 to 24 and / or 25 to 28 Using the respective advantageous properties of the coupling element used, such a device can be optimized as a whole with regard to the criteria of efficiency, compact design and damping of torsional vibrations.

- FIG. 18 shows a longitudinal section through an overall arrangement with the device shown in Figure 16.
- FIG. 1 shows part of a device 1 for coupling two shafts with a coupling element 3, of which only an inner disk 5 is also shown.
- the inner disk 5 has three openings 7 which extend in the circumferential direction 5 and each have two grooves 9 at their ends.
- the channels 9 widen slightly conically in the direction of the openings 7.
- the inner disc 5 has attachment points 11, which are designed here as holes to be provided with screws. Two of the inner disks 5 can be joined together via the fastening points 11 in such a way that their openings 7 with the grooves 9 are each exactly opposite. Opposing channels 9 thus form a spring channel 13 into which an elastic element, in particular a spiral spring designed as a compression spring, can be inserted. At the end of the spring channels 13 there is in each case a spring stop 15, which together form a bearing for the elastic element, in particular the compression spring designed as a spiral spring.
- the inner disc 5 at least one, here three webs 17, each with two stops 19.
- the webs 17, in particular their stops 19, can be used with other elements of the device 1, in particular a vibration damping element, which is not shown here, for transmitting a torque from and to the inner disks.
- FIG. 2 shows an outer disk 21, which is also part of the coupling element 3. Identically designed details are provided with the same reference numbers, so that reference is made to the description of FIG. 1 in this regard.
- a flange 23 with bores 25 can be seen, via which the outer disk 21 can be coupled to a shaft for the transmission of a torque.
- the outer disc 21 also has openings 7, the ends of which, in contrast, have channels 9 'which are somewhat flatter.
- the outer disk 21 can also be joined via the fastening points 11 with a further, essentially mirror-image outer disk such that spring channels 13 'with spring stops 15' result.
- two of the outer disks 21 are connected at a distance via the fastening points 11.
- the distance between the disks 21 and the depth of the channels 9 ' are coordinated with one another in such a way that the compression spring (not shown here) can be stored equally in the spring channel 13' of the outer disks 21 and / or the spring channel 13 of the inner disks 5.
- FIG. 3 shows a top view of the coupling element 3 with two inner disks 5 and two outer disks 21, each of which lies exactly one above the other.
- the inner disks 5 are indicated by dash-dotted lines and the outer disks 21 by means of solid lines.
- the same parts are provided with the same reference numerals, so that reference is made to the description of the preceding figures.
- the coupling element 3 has a sandwich-like structure made up of a total of four disks 5, 21.
- the two inner disks 5 mounted on the inside are firmly attached to one another. which is connected and movable relative to the outer disks 21, which are likewise firmly connected to one another.
- the fixing means of the outer disks 21 used for the fastening points 11 reach through the openings 7 of the inner disks 5 which are covered. It is thus possible that the two outer disks 21 and the two inner disks 5 are each firmly connected to one another and yet can be moved relative to one another.
- Each opening 7 of the disks 5, 21 is assigned two elastic elements 27, which are designed here as coil springs that can be subjected to pressure. It can be seen that each of the elastic elements 27 is supported on both sides in the spring channels 13, 13 '. Each of the elastic elements 27 thus exerts a compressive force on the respective spring stop 15 of the inner disks 5 and the respective spring stop 15 'of the outer disks 21. Since each of the openings 7 is assigned two elastic elements 27, which are each of the same design, one results Rest position, which, based on the length of the openings 7 and the spring channels 13, 13 ', each overlap by 50%.
- An individually considered opening 7 of the inner disks 5 or the outer disks 21 thus corresponds to a spring system consisting of two pressure springs connected in series with a center tap.
- the forces acting on the center tap are transmitted from the inner disks 5 to the outer disks 21 or vice versa. Since it is a ring-shaped arrangement, virtually all elastic elements 27 are connected in series with themselves and alternately transfer their spring forces from the inner disc 5 to the outer disc 21. In the case of a number of elastic, identical elements 27, these are all in the equilibrium state are biased exactly the same, resulting in the 50% coverage described above. Since the openings 7 of the disks 5, 21 and the spring channels 13, 13 'are exactly the same length and radially equally spaced in the circumferential direction, the disks 5, 21 are arranged coaxially in the idle state and the compression springs are each deflected exactly the same.
- the two inner disks 5 and the two outer disks 21 can be rotated relative to one another. Due to the conical design of the spring channels 13, 13 ', it is also possible to bring about an axial offset of the disks.
- the spring forces of the elastic elements 27 counteract the relative rotation and also the axial offset.
- the elastic elements 27 are to be designed in such a way that they have a certain pretension in the equilibrium state and still have sufficient reserve so that they still strike the spring stops 15, 15 'even with maximum rotation or maximum axial displacement of the disks 5, 21.
- At least one vibration damping element 29 is assigned to the coupling element 3, which here has three arc springs 31.
- the arc springs 31 each abut against the stops 19 of the webs 17 of the inner disks 5.
- Torque can be transmitted via the webs 17 of the inner disks 5, the elastic elements 27 and the flange 23 of the inner disk 5. It is advantageous that on the one hand a certain damping of torsional vibrations is possible and the torque transmission can also take place with a certain axial offset.
- three of the elastic elements 27 can stretch to the block, while the three remaining elastic elements 27 relax accordingly, but still on the spring stops 15, 15 ', in order to prevent stop noises when the load is reversed. - Avoid deleting concerns. This minimizes wear, because of the elastic
- FIG. 4 shows a longitudinal section through an overall arrangement 33 with the device 1 and the coupling element 3 for coupling two shafts.
- the same parts are provided with the same reference numerals, so that reference is made to the description of the preceding figures.
- the overall arrangement 33 is an output unit for an internal combustion engine with an engine block 35 indicated here and a self-adjusting dry clutch 37.
- the principle of dry clutches is known, so that it is not dealt with in more detail here.
- a first axis 39, shown in dash-dot lines, of a crankshaft 41 can be seen.
- the crankshaft 41 is assigned to a first rotating mass 43. The assignment takes place here by means of a first connection via a flange 45.
- the first mass 43 is of multi-part design here and has a bearing 47 and stops 49 for the arc springs 31.
- the stops 49 are formed by indentations 51 in the otherwise mass-shaped first mass 43. It is thus possible to transmit a torque to the coupling element 3 from the crankshaft 41 via the vibration damping element 29, in particular the stops 49 and the arc spring 31.
- the coupling element 3 is assigned via the flange 23 to an intermediate piece 53, which in turn is assigned to a second rotating mass 55. It can be seen that the outer disks 21, the intermediate piece 53 and the second mass 55 are rotatably mounted on a second axis 57, which is indicated by dash-dotted lines.
- the second rotating mass 55 is assigned to an output shaft 59, in particular a transmission input shaft, whose axis of rotation also corresponds to the second axis 57.
- the crankshaft 41 of the internal combustion engine and the output shaft 59, in particular the transmission input shaft, are thus offset from one another.
- the axis offset is preferably 4 mm.
- the torque transmission, the compensation of the axial misalignment and the damping of torsional vibrations that occur occur via the vibration damping element 29 and the coupling element 3.
- the design of the rotating masses 43, 55 of the vibration damping elements 29 of the device 1 and the elastic elements of the coupling element 3 can be designed in this way that particularly good transmission properties, i.e. damping properties, result in the respective types of internal combustion engines.
- a starter 60 can be provided, which is only partially shown here.
- Figure 5 also shows a longitudinal section through part of the device 1 before final assembly.
- the same parts are provided with the same reference numerals, so that reference is made to the description of the preceding figures.
- FIG. 5 shows the device 1 without a mounted second mass 55 before the offset of the axes 39, 57 has been set.
- a housing 61 is joined to the engine block 35.
- the housing is guided by means of a pin 63, which is fixed to the engine block 35, and an elongated hole 65 of the housing 61.
- the first rotating mass 43 can be screwed onto the crankshaft 41 via a further intermediate piece 67 with a fixing aid 69.
- the fixing aid 69 can be inserted into a threaded bore 71 of the intermediate piece 53 of the second rotating mass 55.
- a force can be applied to the housing 61 to produce the axis offset of the axes 57, 39, which force is represented by an arrow 73.
- the housing 61 can slide along the pin 63 and the elongated hole 65 until the pin 63 strikes the other side of the elongated hole 65. In this state, which is also shown in FIG. 6, a bore 75 of the housing 61 and a threaded bore 77 of the engine block 35 coincide.
- the housing 61 can thus be fixed through the bores 75, 77 by means of suitable fixing means.
- FIG. 6 shows a further longitudinal section of the device 1 shown in FIG. 5, but in the fully assembled state with the second mass 55 and the offset of the axes 39, 57.
- the same parts are provided with the same reference numbers, so that in this respect the description of the FIGS previous figures.
- the housing 61 is fixed to the engine block 35 by means of a screw 79 which is screwed into the bores 75, 77 in such a way that the pin 63 strikes the upper end of the elongated hole 65 of the housing 61.
- the outer disks 21, the intermediate piece 53 and the second mass 55, which are firmly connected to one another, are rotatably mounted on the housing 61 by means of bearings 81, 83 about the second axis 57. It can also be seen that the outer disks 21 are designed differently.
- the outer disk 21 shown in FIG. 2, which has the flange 23 which is associated with the intermediate piece 53, is firmly connected to a further inner disk 21 '.
- the inner disk 21 ' has a larger central opening 85 through which the inner disks 5 can be supported.
- the inner disks 5 are also designed differently, an inner disk 5 'transmitting radial bearing forces to a bearing 87.
- the disks 5, 5 ' are fixed to one another in such a way that they are in contact with each other, and are bent in the region of the bearing 87 in such a way that a bearing seat for the bearing 87 results, via which axial forces can also be transmitted.
- the inner bearing seat of the bearing 87 is formed by the intermediate piece 67 flanged to the crankshaft 41 and the first mass 43. The crankshaft 41, the first mass 43 and the intermediate piece 67 are thus rotatably supported against the inner disks 5, 5 '.
- the bow spring 31 of the vibration damping element 29 in the device 1 interacts with the webs 17 of the inner disks 5, 5 'of the coupling element 3 and the stops 49 of the first mass 43 formed by the indentations 51, the angle of rotation is limited.
- the vibration damping element 29 can absorb or release energy or at least partially convert it into friction energy. This realizes the principle of a torsional vibration damper. It is advantageous with this arrangement that in addition to the implementation of a torsional vibration damping system, the coupling element 3 can also cause the axes 57, 39 to be axially offset and additional damping to take place.
- a further advantage is that the two masses 43, 55 are decoupled from one another by the torsional vibration damper that is implemented. It can also be seen that the coupling element 3 is arranged between the two masses 43, 55, that is to say is completely integrated into the device 1. Thus, the installation space required by the device 1 is not larger than in a conventional so-called two-mass flywheel, which also has a first mass 43 and a second mass 55 and, for example, an arc spring 31.
- FIG. 7 shows a modified section of the device 1 shown in FIGS. 5 and 6.
- the same parts are provided with the same reference numbers, so that reference is made to the description of the preceding figures.
- FIG. 7 shows that the force indicated by the arrow 73 in FIG. 5, which is necessary to produce the offset of the axes 39, 57 during the assembly of the housing 61 of the device 1, can be applied by a screw 89 ,
- the screw is screwed into a threaded bore 91 of the housing 61 until it strikes the first mass 43. Since the housing 61 is assigned to the second axis 57 via the bearings 81 and the first mass 43 is assigned to the second axis 57 via the bearing 87, the axes 39, 57 can thus be offset against the forces of the elastic elements 27 of the coupling element 3.
- the housing 61 becomes like described in Figure 6, fixed to the engine block 35 by means of suitable fixing means.
- the screw 89 must be removed again or at least unscrewed to such an extent that it does not hinder the rotational movement of the first mass 43. If the screw 89 is removed again, the bore 91 must be closed again since the device has oil lubrication.
- the oil lubrication of the device is briefly discussed below.
- the oil is conducted into the interior of the housing 61 via a central bore 93 of the crankshaft 41 via an oil guide element 95 and an oil channel 97 of the intermediate piece 53. Due to the centrifugal forces, the oil is distributed within the housing 1 in order to then be discharged again through an opening, not shown here.
- FIG. 8 shows a further coupling element 101, which is in particular part of a device 103 for coupling two shafts.
- the coupling element 101 has two ball joint arrangements 105 which are arranged and constructed in mirror image to one another. Parts mirrored opposite each other are described in the singular.
- the ball joint arrangement 105 has a ball shell 107 with an inner ball socket 109 and an outer ball head 111.
- the spherical shell 107 is fixed on an intermediate shaft 115 with the aid of a fixing pin 113.

- the intermediate shaft 115 has an inner ball head 119 at both ends, which is part of the ball joint arrangement 105.
- the ball heads 111 and 119 each have at least one spherical section surface, of which a first spherical section surface 121 of the inner spherical head 119, which is perpendicular to the image plane in FIG. 8, is visible.
- the spherical section surface of the outer spherical head 111 lies parallel to the image plane and is therefore not visible in the illustration according to FIG. 8.
- Each of the spherical section surfaces interacts with a counter surface of the corresponding spherical socket which is adapted to this.
- the first spherical section surface 121 thus interacts with a
- two spherical section surfaces 121 are provided which interact with two corresponding counter surfaces 123.
- the crankshaft 129 is rotatably mounted about a first axis 131, which is indicated here by dash-dotted lines. Due to the gimbal mechanism realized by the ball joint arrangement 5, rotation of the crankshaft 129 about the first axis 131 causes rotation of the intermediate shaft 115 about an intermediate axis 133, which is also indicated by dash-dotted lines.
- the second ball-and-socket arrangement 105 of the intermediate shaft 115 which is constructed symmetrically here, interacts with a further intermediate piece 135, which can be assigned to an output shaft, which is not shown here, with a second axis 137, which is shown in broken lines.
- the universal joint arrangement 5 of the intermediate shaft 15 thus realizes two universal joints, so that despite the axial offset between the crankshaft 129 and the output shaft, not shown, that is to say the axes 31, 37, a rotary movement, in particular a torque of up to 1000 Nm, can be transmitted ,
- the output shaft not shown here, itself with a ball joint arrangement 5, so that an angled output is realized.
- the angle which the intermediate axis 133 makes to the axes 31, 37 is 6 °.
- the intermediate pieces 125 are assigned to two rotating masses and one vibration damping element.
- FIG. 9 shows a longitudinal section of a further device 103 'for coupling two shafts with a coupling element 101'.
- the same parts are provided with the same reference numerals, so that reference is made to the description of FIG. 8.
- An intermediate shaft 115 'with the ball joint arrangement 105 and a ball joint 139 with a ball head 141 and a ball socket 143 can be seen.
- the ball head 141 and the ball socket 143 of the ball joint 139 are here only designed as ball zones, that is to say as two-sided, parallel cut spherical surfaces.
- the ball joint 139 thus enables the associated intermediate shaft 115 'to wobble and to rotate about the intermediate axis 133.
- the ball socket 143 is assigned to a swash plate 145.
- the swash plate 145 is fixed to the intermediate shaft 115 'by means of suitable fixing means 147.
- a spherical bearing 149 is also fixed to the swash plate 145 and the intermediate shaft 115 'via the fixing means 147.
- a vibration damping element 151 which is designed here as a linear spring damper element 151, is connected via the spherical bearing 149. Spring damper systems, in particular with spiral springs, are known, so that they will not be discussed further here.
- the vibration damping element is connected between the spherical bearing 149 and a further spherical bearing 155.
- This spherical cap bearing 155 is connected to a first rotating mass 159 by means of suitable fixing means 157.
- the first rotating mass 159 can be connected via a flange 161 to a shaft with a first axis 163, which is shown here in broken lines.
- the shaft is, in particular, a crankshaft 165 of an internal combustion engine.
- the state shown in FIG. 9 corresponds to the idle state.
- the vibration damping elements 151 are arranged radially to the first axis 162 of the crankshaft 165.
- a wobble movement causes a deflection of the vibration damping elements 151 with respect to the plane of rotation of the crankshaft 65.
- a relative rotation of the crankshaft with respect to the intermediate shaft 115 causes a deflection of the vibration damping elements with respect to an imaginary diameter line.
- the vibration damping elements counteract the rotation and limit the maximum possible rotation angle.
- a wobble movement or a relative rotation causes the vibration damping element 151 to be lengthened or shortened, so that it can absorb or release energy.
- An angled transmission of a rotary movement from the first axis 163 to the intermediate axis 133 of the intermediate shaft 115 ' is therefore possible.
- a torque in particular up to 500 Nm, can be transmitted via the device 103 ′ while damping torsional vibrations.
- the coupling element 103 ' can be designed to be weaker. This rotary movement and the torque can be further transmitted from the intermediate shaft 115 'to the intermediate piece 135, which is assigned to the ball joint arrangement 105.
- the intermediate piece 135 is in particular assigned to an output shaft, which is not shown here, and / or a second rotating mass, which is also not shown here.
- the intermediate piece 135 is rotatably supported by means of suitable bearings 167, the axis of rotation of which is a certain can take any angle and / or axial offset to the first axis 163.
- An axial offset of 4 mm and an angular offset of the intermediate axis 133 to the first axis 163 of 6 ° are preferred.
- FIG. 10 shows a further advantageous device 103 "with a coupling element 101".
- the same parts are provided with the same reference numerals, so that reference is made to the description of FIGS. 8 and 9.
- a first shaft 169 and a second shaft 171 can be seen.
- the shafts 169, 171 are coupled via the device 103 "and the coupling element 101".
- the intermediate shaft 115 ′′ is assigned to two swash plates 145, which lie opposite one another in mirror image.
- the device 103 ′′ has a further rotating mass 173 constructed in mirror image.
- the entire device 103 ′′ is characterized here by parts constructed in mirror image relative to one another. However, a different design is also conceivable, in which parts opposite one another in mirror image are dimensioned and designed differently. Since a detailed description has already been given for FIG the functionality will be discussed.
- the swash plates 145 perform a complete wobble movement relative to the masses 159, 173 within a wobble range which corresponds to the angle between the first axis 163 and the intermediate axis 133 of the intermediate shaft 115 ′′
- the vibration damping elements 151 absorb and at least partially release energy in accordance with their lengthening and shortening. If torque is transmitted in addition to the rotary movement, the vibration damping elements 151 are also deflected with respect to an imaginary diameter line the vibration damping elements 151 are additionally lengthened, as a result of which they absorb energy or convert them to frictional energy to a desired extent.
- the coupling element 101 is part of this vibration damping system. This results in a particularly compact construction of the arrangement. Depending on the design of the vibration damping elements, more or less energy is converted into friction. It is thus possible to optimize the device 103 "in terms of efficiency, compact design and damping of torsional vibrations. Also in this arrangement, the coupling element 101" is arranged between the rotating masses 159 and 173, which results in a small space requirement for the device 103 " ,
- FIGS. 11 to 13 show a coupling element 201, in particular for a device 203 for coupling two shafts, and various partial assemblies of the device 203.
- the coupling element 201 shown in FIGS. 11 and 12 has an eccentric 205 which is assigned to an eccentric bolt 207 and a clutch plate 209.
- the coupling element 201 here has a total of six eccentrics 205 with the associated eccentric bolts 207, of which only one is visible because of the cut along the line Xl-Xl shown in FIG. It is possible to provide more or fewer eccentrics 205 on the clutch plate 209.
- the eccentric 205 is rotatably mounted about an eccentric axis 211 and a pin axis 213, which are each indicated by dash-dotted lines.
- the eccentric pin 207 is assigned to two disks 215, 215 '.
- the eccentric 205 is introduced into a bore 217 of the clutch plate 209, the drilling axis of which corresponds to the eccentric axis 213.
- the eccentric 205 is freely rotatable in the bore 217.
- the discs 215, 215 'and the clutch plate 209 are coupled via the eccentric 205 with its eccentric pin 207.
- the clutch plate 209 can thus be moved up and down on a circular path with a radius which corresponds to the distance between the axes 211, 213.
- the coupling element 201 is in particular associated with a first rotating mass 219, which is shown in FIG. 11, and a second rotating mass 221, which is shown in FIG. 13.
- the assignment is made using suitable fixation means, in particular using a flange. It is also possible to replace it with a flange established fixed connection of the rotating masses 219, 221 for at least one of the masses 219, 221 to choose a connection that allows a relative rotation.
- Such a connection of the first mass 219 to the disks 215, 215 ' is shown in FIG.
- the first rotating mass 219 is screwed onto a bearing plate 225 via a flange 223.
- a bearing area 227 of the disk 215, a bearing shell 231 and a bearing area 229 of the bearing plate 225 form a friction bearing 232 for the disks 215, 215 ′, which are firmly connected to one another via the eccentric bolts, about a first axis of rotation 233, which is indicated by dash-dotted lines.
- the first rotating mass 219 is also rotatably supported about the first axis 233 by means of a bearing, not shown here.
- the first rotating mass 219 and the disks 215, 215 ' are rotatably supported about the first axis 233 via the bearing (not shown here) and the friction bearing, the disks 215, 215' being rotatable relative to the first rotating mass 219.
- the coupling of the two disks 215, 215 'and the first masses 219 takes place via a vibration damping element 235, which here comprises an inner bow spring 237, an outer bow spring 239, a friction bearing 241 for the outer bow spring 239 and the friction bearing 232 described above.
- the vibration damping element 235 absorbs or releases energy corresponding to the angle of rotation or converts some of it into friction energy.
- the principle of a torsional vibration damping system is thus realized by the device 203 shown in FIGS. 11 to 13.
- the rotating the masses 219, 221 and the vibration damping element 235 are to be designed for the respective application, ie for the torsional vibrations to be expected. It does not matter what type of bearings 232, 241 are used. Ball bearings, roller bearings, plain bearings or other known bearings are also possible at this point.
- Torque is transmitted from the vibration damping element 35 to and from the first rotating mass 219 via stops 245, which are not visible here and are formed by indentations 247 of the otherwise plate-shaped rotating first mass 219.
- the stops 245 are slightly ahead and somewhat behind the image plane.
- a certain torque transmission takes place due to the friction via the bearings 232, 241.
- the rotating mass 221 and the coupling plate 209 have a flange 253, via which they can be screwed.
- the second mass 221 shown in FIG. 13 has a ring gear 255, via which it can be driven, for example by an electric motor or a starter for internal combustion engines.
- an anti-loss device in particular a central bore for inserting a screw, can be provided.
- FIG. 14 shows a schematic cross section of the coupling element 201 shown in FIGS. 11 and 12. The same parts are provided with the same reference numbers, so that reference is made to the description of FIGS. 11 and 12.
- the coupling plate 209 can be seen, which has a total of six bores 217 into which the eccentrics 205 are introduced.
- the axial offset of the axes 233 and 243 is indicated by two dashed lines 257, which corresponds to the offset of the pin axis 211 and the eccentric axis 213, which is also indicated by two lines 259.
- the pin axes 211 of the eccentric pins 207 which are assigned to the disks 215, 215 'and thus to the first mass 219, are equally spaced radially from the first axis 233.
- the eccentric axes 213 of the eccentric 205 which are assigned to the clutch plate 209 and thus to the second mass 221, are radially equally spaced from the second axis 243.
- the eccentrics 205 and their eccentric bolts 207 act like connecting rods, which couple the clutch plate 209 to the disks 215, 215 '.
- FIG. 15 shows an eccentric 205 of the coupling element 201.
- the same parts are provided with the same reference numbers, so that reference is made to the description of the preceding figures.
- the eccentric 205 and the eccentric pin 207 are surrounded by bearing areas 261.
- the bearing areas 261 can be designed from a tribological point of view in such a way that minimal wear and minimal friction occur in order to achieve the longest possible service life and good efficiency of the coupling element 201. It is also advantageous that the eccentric 205 is coupled to the crankshaft 263 via the vibration damping element 235, which likewise minimizes friction and wear.
- the bearing areas 261 are designed as friction bearings.
- other advantageous bearing principles are also conceivable, for example ball bearings, roller bearings or the like.
- FIG. 16 shows the device 203 shown in FIGS. 11 to 13 in the assembled state.
- the disks 215, 215 ' are assigned via the flange 223 to a crankshaft 263 of an internal combustion engine.
- the axis of rotation of the crankshaft 263 consequently corresponds to the first axis 233.
- the crankshaft 263 is mounted eccentrically with respect to an engine block 267 of the internal combustion engine. This eccentric movement, which also displaces the first axis 233, can be used to change the compression of the internal combustion engine.
- the path curve of the first axis 233 of the crankshaft 263 caused by the eccentric piece 265 is indicated in FIG. 14 by a semicircle 269.
- the eccentricity of the first axis 233 of the crankshaft 263 caused by the eccentric piece 265 shown in FIG. 16 corresponds exactly to the offset of the axes 233 and 243. Since the inner disks 215, 215 'and the first mass 219 are flanged to the crankshaft, an adjustment of the crankshaft.
- the second mass 221 is fixedly connected to the coupling plate 209 by the flange 253 and is rotatably mounted together with the latter by means of suitable bearings 271 relative to a housing 273 of the device 203.
- the housing 273 in turn is firmly connected to the engine block 267. Since the eccentricity of the crankshaft 263, which is caused by the eccentric piece 265, corresponds exactly to the axial offset of the axes 233 and 243, by adjusting the crankshaft 263, the axis 233 thereof is guided around the second axis 243 of the second mass 221 at a constant distance. This axial offset, however, is compensated for by the arrangement of the disks 215, 215 ', the eccentric 205 and the clutch plate 209. It is therefore possible, despite an adjustment of the crankshaft axis 233 of the second one Mass 221 to assign a fixed shaft, for example an output shaft, in particular a transmission input shaft.
- the coupling element 201 is completely integrated into the device 203, which compensates for the axial offset between the crankshaft 263 and the output shaft.
- the installation space of the device 203 is thus particularly small. Since the transmission of the torque over the axial offset does not cause any radial bearing forces, the bearing losses are particularly low.
- the device 203 thus represents an optimal compromise in terms of efficiency, compact design and damping of torsional vibrations.
- FIG. 17 shows the bolt circle of the flange 253 of the device 203 shown in FIG. 16.
- the same parts are provided with the same reference numbers, so that reference is made to the description of the preceding figures.
- the bolt circle of the flange 253 is arranged offset with respect to its axis of rotation, that is to say the first axis 233 or the crankshaft axis 233.
- the offset is indicated by the two lines 257 and corresponds exactly to the axial offset of the axes 233, 243.
- the bolt circle of the flange is therefore arranged eccentrically to the first axis 233 and centrally to the second axis 243. This is advantageous when assembling the device 203, which will be briefly discussed below with reference to FIG. 16:
- the screw connection of the flange 253 is made by means of an assembly aid 275, which can be introduced into a bore 277 of the flange 253 for this purpose Crankshaft 263 and the first mass 219 manufactured.
- the flange 253 also has a bolt circle which has the same diameter of the bolt circle of the flange 223 and is arranged centrally to the axis 243 of the second mass 221. The bolt circles of the flanges 223 and 253 can thus be brought to cover exactly, so that the assembly aid 275 can be inserted into the bore 277 of the flange 253 for tightening the flange 223.
- FIG. 18 shows the device 203 with the coupling element 201 in combination with the internal combustion engine indicated by the partially illustrated engine block 267 and a dry clutch 279.
- the same parts are provided with the same reference numbers, so that reference is made to the description of the preceding figures.
- the dry clutch 279 is assigned the second rotating mass 221, which is in particular a cast plate, by means of suitable connecting means 281. Depending on the actuation position of the clutch 279, a rigid connection to an output shaft 283, in particular a transmission input shaft, can be established.
- the axis of rotation of the output shaft 283 corresponds to the second axis 243, that is to say the axis of rotation of the second rotating mass 221.
- the adjustable crankshaft 263 and the output shaft 283 are coupled via the device 203 to the coupling element 201 despite the axial offset of the axes 233, 243, that torque or a rotary movement can be transmitted in the smallest installation space while damping torsional vibrations with good efficiency.
- the device 203 has oil lubrication.
- oil channels 285 are provided in the various components, some of which are shown with dashed lines.
- various oil lakes 287 are provided for oil guidance, which are indicated by horizontal lines. The oil lakes 287 form due to the centrifugal forces acting on the oil, which is carried away by the rotating parts of the device 203.
