Definitions
- the invention relates to a hydrodynamic coupling device, in particular a torque converter or a fluid coupling, comprising a housing arrangement, a turbine wheel provided in the housing arrangement, a lock-up clutch arrangement, by means of which a torque transmission connection between the turbine wheel and the housing arrangement can optionally be established, the lock-up clutch arrangement comprising: at least - At least one essentially ring-like friction element connected to the turbine wheel for common rotation about an axis of rotation with a friction surface area and a pressing element which is connected to the housing arrangement for common rotation about the axis of rotation and through which the friction surface area of the at least one friction element for establishing the torque transmission connection can be acted upon between the turbine wheel and the housing arrangement.
- Bridging clutch arrangement has two friction elements coupled to the turbine wheel for common rotation, between which an intermediate friction element coupled to the housing arrangement for common rotation is positioned.
- the individual friction surface regions of the friction elements, the intermediate friction element, the clutch piston and the housing arrangement are brought into mutual interaction by the clutch piston, which is radially connected to the housing arrangement and acts as a pressing element.
- a disadvantage of the known coupling devices of the type described above is that a connection arrangement is provided for connecting the friction element or elements to the turbine wheel, said connection arrangement “bypassing” the pressure element on its outer circumference.
- This connection takes up space and increases the weight of the coupling device.
- the arrangement of the additional mass in the radially outer region also leads to a particularly pronounced increase in the moment of inertia of the turbine wheel.
- a disadvantage of the known coupling device with regard to the total weight is also the mounting of the radially inner region of the pressing element on a section projecting axially from the housing arrangement into the interior thereof.
- the pressing element is connected to the housing arrangement in a substantially rotationally rigid manner radially outside the friction surface area.
- connection of the pressing element provided radially outside the friction surface area creates the possibility of connecting the friction element (s) to the turbine wheel in a much simpler manner without any significant additional effort.
- the friction elements can be connected to the turbine wheel without bypassing the radially outer circumference of the pressure element, so that the mass of the coupling device and the moment of inertia of the turbine wheel are kept small.
- the pressing element is preferably connected to the housing arrangement via an elastic device, in particular a tangential leaf spring arrangement.
- an elastic device in particular a tangential leaf spring arrangement.
- this device should be arranged in a radially outer region of the pressing element.
- the pressing element on its outer circumference with radial indentations, so that when the coupling device is assembled, the leaf springs can first be fastened, for example riveted, to the radial lugs of the pressing element remaining on the outer circumference, in order to later free ones located in the area of the radial indentations
- a riveting of the leaf spring ends on the housing side is preferably carried out on housing pins which are formed by a local deformation (for example pressing in) of the housing material.
- the pressing element is preferably axially displaceable on the turbine wheel and rotatably mounted relative to the turbine wheel. This avoids a projection of the housing arrangement provided in known coupling devices for the mounting of the pressing element or an additional component. With regard to driving the pressing element by pressurization, this measure also allows fluid sealing between the inner circumference of the pressing element and the turbine wheel.
- the pressing element is preferably mounted on the peripheral surface of a hub of the turbine wheel.
- the at least one friction element if desired via a torsional vibration damper, is connected to the turbine wheel in a substantially torsionally rigid manner radially within the friction surface area.
- the friction element can comprise a friction element support section that extends radially inward starting from the friction surface area. If a plurality of friction elements are provided, each of these elements can have a friction element carrier section running in this way.
- a radially inward extending, common to the friction elements Friction element carrier section is provided, which is connected on its inner circumference to the turbine wheel, in particular the turbine wheel hub, and on its outer circumference carries a friction element driver for driving, in particular positive driving, of the individual friction elements.
- a common friction element carrier can be connected to the turbine wheel, for example, by means of a weld. It should be noted here that a weld in the region of the turbine wheel hub advantageously avoids any deformation in the region of the turbine wheel shell.
- the friction element carrier section or sections should extend substantially axially in order to save material. However, it is entirely possible to provide a course deviating therefrom, in particular a substantially straight oblique course, for example in order to bridge an axial offset between the friction surface area and the point at which the connection to the turbine wheel takes place.
- connection to the turbine wheel is preferably made via radial toothing, which is preferably provided between the friction element (or friction element carrier) and a peripheral surface of a turbine wheel hub.
- a plurality of friction elements is provided, wherein an intermediate friction element which is connected to the pressing element in an essentially rotationally rigid manner is arranged in each case between the friction surface regions of two adjacent friction elements.
- the torsionally rigid connection to the pressing element ensures in a simple manner the entrainment of the intermediate friction element when the housing arrangement rotates.
- Each intermediate friction element or a plurality of intermediate friction element carriers common extends preferably engaging in driving recesses of the pressing element.
- the entrainment recesses are formed by the radial indentations already mentioned above on the outer circumference of the pressing element, which are thus given a further function.
- a particularly simple construction of a hydrodynamic coupling device which works according to the principle of a 2-line system, can be obtained by dividing the interior of the housing arrangement into a first spatial area, in which the turbine wheel is arranged, and a second spatial area by the pressing element and that for the exchange of working fluid provided in the interior, working fluid can be introduced into the first room area and working fluid can be discharged from the second room area, or vice versa.
- working fluid can be introduced into the first room area and working fluid can be discharged from the second room area, or vice versa.
- Flow channel arrangement is provided.
- This flow channel arrangement is then preferably open to the two spatial areas, so that due to the pressure difference between the two spatial areas, which is already present in these coupling states, a fluid passage will take place through the flow channel arrangement and the thermal energy generated in this spatial area can be efficiently dissipated.
- the coupling device according to the invention can also be designed as a so-called 3-line system, in which two fluid lines for fluid exchange and a further fluid line for fluid pressure-controlled actuation of the clutch piston are provided.
- the housing arrangement has a shape which is adapted to the contour of the bridging coupling arrangement and has an axial bulge in the region of the bridging coupling arrangement.
- the housing arrangement is designed with a higher degree of rigidity, in particular in its area which is also provided for the lockup clutch arrangement or for its effect. This leads to a significantly lower bulging or a significantly lower inflation of the housing arrangement under the fluid pressure prevailing inside the housing. Therefore, even with friction areas that are relatively wide in the radial direction, an edge loading of friction linings or the like induced by bulging cannot occur.
- an essentially ring-shaped coupling element For coupling the coupling device according to the invention to a drive shaft, an essentially ring-shaped coupling element can be provided, which is connected in its radially inner region to an outside of the housing arrangement, preferably by laser welding, and fixed in its radially outer region for coupling to a drive shaft connected or connectable second coupling element is formed.
- a ratio of an outside flow diameter in the region of the turbine wheel to an outside friction diameter of the at least one friction element in the region of 1.30 to 1.80, preferably 1.35 to 1.70, and / or that a ratio of an outer friction diameter of the at least one friction element to an inner friction diameter of the at least one friction element is in the range from 1.10 to 1.30, preferably 1. , 15 to 1, 25.
- FIG. 1 is a partial axial sectional view of a hydrodynamic coupling device according to the invention.
- FIG. 2 shows a detailed view in the direction of arrow II in FIG. 1.
- FIG. 1 shows a hydrodynamic torque converter 10, comprising a housing arrangement 12, a turbine wheel 14 provided in the housing arrangement 12 and a lock-up clutch arrangement 16.
- the housing arrangement 12 comprises a housing cover 18 which is fixedly connected in its radially outer region, for example by welding, to an impeller shell 20. Radially on the inside, the impeller shell 20 is firmly connected to an impeller hub 22. On its inner side facing the housing interior 24, the impeller shell 20 carries a plurality of impeller blades 26 that follow one another in the circumferential direction. The impeller shell 20 together with the impeller hub 22 and the impeller blades 26 essentially form an impeller 28.
- the housing cover 18 is also on its outer side a centering pin 34 arranged coaxially to an axis of rotation A, which is inserted into a corresponding centering recess of a drive shaft, not shown, for example a crankshaft of an internal combustion engine, for aligning the axis of rotation A of the torque converter 10 with respect to the axis of rotation of the drive shaft.
- the turbine wheel 14 is arranged in the interior 24 of the converter 10 and, in the radially outer region, comprises a turbine wheel shell 36 which carries a plurality of turbine wheel blades 38 on its side facing the pump wheel 28. Radially on the inside, the turbine wheel shell 36 is firmly connected to a turbine wheel hub 40, for example by welding or screwing at 39.
- the turbine wheel hub 14 can in turn be connected in a rotationally fixed manner to an output shaft, for example a transmission input shaft.
- a stator 42 is provided axially between the pump wheel 28 and the turbine wheel 14.
- the stator 42 comprises on a stator ring 44 a plurality of stator blades 46 positioned between the radially inner end portions of the impeller blades 26 and the turbine blades 38.
- the stator ring 44 can be rotated in a direction around the axis of rotation A via a freewheel arrangement 48 on a support element (not shown), for example a hollow support shaft, but is blocked against rotation in the other direction of rotation.
- the stator 42 is axially supported via two bearing arrangements 50, 52 with respect to the pump wheel 28 on the one hand and with respect to the turbine wheel 14 on the other hand.
- the lock-up clutch arrangement 16 serves to establish a direct mechanical torque transmission connection between the turbine wheel 14 and the housing arrangement 12 and comprises a coupling piston 56 which, with a radially inner cylindrical section on an outer circumferential surface of the turbine wheel hub 40, is axially displaceable via a slide bearing 58 and rotatably supported relative to the turbine wheel 14 is.
- the coupling piston 56 is connected at its radially outer end region to the housing cover 18 in an essentially torsionally rigid manner via an elastic arrangement, in the example shown a tangential leaf spring arrangement 60.
- the clutch piston 56 is thereby held axially movable with respect to the housing cover 18.
- the lock-up clutch arrangement 16 further comprises two disk or friction elements 62, 64, which in their radially outer region each have friction linings 66, 68, 70, 72 on both axial end faces.
- each friction element 62, 64 comprises a friction element carrier section 74, 76, which extends radially inward from a friction surface region R defined by the expansion of the friction linings 66, 68, 70, 72.
- the friction element carrier sections 74, 76 are formed in one piece with the sections of the friction elements 62, 64 that carry the friction linings.
- the friction element carrier sections 74, 76 are formed at their radially inner end region with an internal toothing which is in meshing engagement with a corresponding external toothing 80 of the turbine wheel hub 40. A torsionally rigid connection is thus created between the friction elements 62, 64 and the turbine wheel 14.
- Axially between the two friction elements 62, 64 is an intermediate friction element 82 which, starting from the friction surface area R, extends radially outward and engages in driving recesses 84 of the clutch piston 56.
- a torsionally rigid connection is thus created between the intermediate friction element 82 and the clutch piston 56 and thus the housing arrangement 12.
- the interior space 24 of the housing arrangement 12 is divided by the clutch piston 56 into a first space area 86, in which the turbine wheel 14 is arranged, and a second space area 88.
- the fluid pressure in the room area 86 is increased above the fluid pressure prevailing in the room area 88.
- fluid can be introduced into the space region 86 via a passage opening arrangement 90 in the region of the stator 42 by a fluid pump (not shown) via an intermediate space formed, for example, between the output shaft (not shown) and a support hollow shaft become.
- the fluid can then enter the area 88 by flowing around the friction elements 62, 64 and flow via a through-opening arrangement 92 leading radially inward through the output shaft and from there to a fluid reservoir (not shown).
- a fluid reservoir not shown.
- at least one fluid passage opening 94 is provided in the clutch piston 56 radially within the friction surface area R, which enables the fluid exchange between the first space region 86 and the second space region 88.
- the friction linings 66, 68, 70, 72 can have lining grooves with, for example, an arcuate course, which are open in the radially outer region towards the spatial region 86 and are open in the radially inner region towards the spatial region 88, so that they are also completely bridged or in the slip region Condition which can be dissipated more quickly by the flow of fluid in the area of the friction linings 66, 68, 70, 72.
- the outer friction diameter b of the friction linings 66, 68, 70, 72 is kept comparatively small.
- a ratio of the outer fluid flow diameter a which approximately corresponds to the outer diameter of the turbine wheel 32, has a value in the range from 1.35 to 1.70 with respect to the outer friction diameter b.
- the ratio between the outer friction diameter b and the inner friction diameter c of the friction linings 66, 68, 70, 72 is preferably in a range from 1.15 to 1.25. This leads to a comparatively large radial extent of the ring-shaped friction linings and thus to one comparatively large possible power loss in the area of the lockup clutch arrangement.
- the housing arrangement 12 has a shape which is adapted to the contour of the lock-up clutch arrangement 16 and has an axial bulge 96 in the region of the lock-up clutch arrangement 16.
- An advantageous stiffening of the housing arrangement 12 is thus created by the contour of the housing cover 18 which is bent radially on both sides of this bulge 96.
- the working fluid provided in the interior 24 under pressure prevents the housing 12 from bulging or swelling, with the disadvantageous consequence of edge loading in the region of the outer friction lining 66.
- an axial indentation can alternatively also be provided, through which the same advantageous effect can be achieved and, furthermore, the axial installation space can be further reduced. In the latter case, for optimal use of the installation space, it is expedient if the friction surface area R of the lockup clutch arrangement 16 is arranged completely radially within the radial center of the turbine wheel shell 36.
- the torque converter 10 can of course also have more than two friction elements 62, 64, for example three friction elements, and then a correspondingly larger number of intermediate friction elements 82. Only one friction element can also be used.
- FIG. 1 Another advantage of the torque converter 10 shown lies in the way in which it is connected to a drive shaft.
- a ring-shaped coupling element 98 which, for example, is cranked in the axial direction and is formed, for example, from sheet metal.
- this coupling element 98 is preferably attached to the outside of the housing cover 18 by laser welding. Laser welding is advantageous here since it results in practically no deformation of the housing cover 18 and any deformation in the region in which the housing cover 18 provides a friction surface on its inside would be disadvantageous.
- the coupling element 98 In its radially outer area, the coupling element 98 carries a plurality of nut elements 100 or the like, into which screw bolts or the like can be screwed in order to connect the coupling element 98 to a flexible plate or the like, such a plate in a manner known per se in its radially inner area can be screwed to a drive shaft, for example a crankshaft flange.
- FIG. 2 shows a view marked II in FIG. 1 in the area of the essentially torsionally rigid connection between the clutch piston 56 and the inside of the housing cover 18.
- the end of the tangential leaf spring 104 on the piston side is fastened to radial tabs 110 of the clutch piston 56 by riveting at 108.
- a plurality of tangential leaf springs 104 are provided distributed over the circumference of the clutch piston 56, which ensure that the clutch piston 56 can be axially displaced during operation of the lock-up clutch arrangement 16.
- the driver recesses 84 of the clutch piston 56 are also arranged distributed in the circumferential direction, into which engage radially outwardly projecting tabs of the intermediate friction element 82.
- These take-out recesses 84 can alternatively also be provided in each case by a section (for example the bottom) of the radial indentations 102, for example as shown in dashed lines in FIG. 2.
- the cover pins 106 as shown in FIG. 1, are formed by pressing in the housing cover 18.
- the intermediate friction element or elements could also be coupled in a rotationally fixed manner to the housing cover.
- a friction element carrier common to the friction elements could also be provided radially within the friction surface region, which holds the individual friction elements axially displaceably and is coupled in a rotationally fixed manner to the turbine wheel on its radially inner region.
- Such a friction element carrier can also be designed as a torsional vibration damper in order to meet special vibration requirements.
