Description

The present invention relates to a disk basket or a disk carrier, in particular an outer disk carrier, for a multiple clutch, in particular a double clutch with a radial arrangement of two coupling devices, for a drive train of a vehicle, in particular a motor vehicle. Furthermore, the invention relates to a method for producing a slat basket or a plate carrier for a multiple clutch. Furthermore, the invention relates to a coupling device, a torque transmission device, a clutch or a transmission, in particular a double clutch or a dual-clutch transmission, for a drive train of a vehicle, in particular of a motor vehicle.

An internal combustion engine of a motor vehicle gives a usable power to a motor vehicle driver only in a certain speed range. In order to use this speed range for different driving conditions of the motor vehicle, this requires an automatic or manually switchable transmission. Such a transmission is mechanically coupled via a clutch with the internal combustion engine. Due to different and also increased demands on actuation forces, on a performance and to be transmitted engine torque of the clutch, a variety of clutches in the drive trains of motor vehicles are used. For example, dry or wet-running single-disc or multi-disc clutches are used, and these may be designed as single, double or multiple clutches.

In addition to a main function of connecting and disconnecting a crankshaft of the internal combustion engine or an output shaft of an electric motor with and from a transmission input shaft of the motor vehicle, the clutch has a number of other important tasks. It should allow a smooth and smooth starting of the motor vehicle, ensure a fast gearshift, keep torsional vibrations of the engine from the transmission and thus reduce rattle noise and wear, as an overload protection for the (entire) powertrain, z. As in switching errors serve, as well as wear and easy to be interchangeable. Here, the coupling should be cost-effective in their production, their installation and / or their operation with a small space consumption in the drive train.

Various configurations of outer and inner disk carriers for clutch devices of multi-disc clutches are known from the prior art, in / on which a plurality of friction disks of a friction pack can be accommodated. The friction lamellae of the friction pack are suspended or supported in / on the outer or inner disk carrier in question in such a way that they are respectively axially displaceable and rotationally fixed to the outer or inner disk carrier, the outer disk carrier and inner disk carrier in turn having an input - or output shaft, or vice versa, the coupling device is rotationally fixed connected.

Due to the axial displaceability of the friction plates in / on the relevant plate carrier, the friction plates can be pressed together so that the alternately arranged in the outer plate carrier and the inner plate carrier friction plates frictionally connected to each other (clutch engaging) but also can be solved again (clutch disengaging). By using a plurality of friction plates with each blade a friction surface and thus a transmittable torque is increased. A disadvantage of the previously known configurations of disc carriers is that they are either expensive to produce or expensive to assemble.

It is an object of the invention to at least partially overcome the disadvantages known from the prior art and to provide a cost-effective and / or an easily mounted plate carrier, in particular an outer plate carrier, for a coupling device of a multiple clutch. Furthermore, the disk carrier according to the invention or the coupling device according to the invention should be cost-effective in their maintenance and / or their operation with a low space requirement in the drive train. - Furthermore, it is an object of the invention to provide a corresponding coupling device, a corresponding torque transmission device, a corresponding clutch and / or a corresponding transmission.

In the following, a coupling device or a coupling is generally understood to mean a machine element which serves for a mechanically releasable connection of two preferably coaxial shafts, in particular an output drive shaft and a drive shaft of a motor vehicle or commercial vehicle, or two preferably coaxial machine elements. The coupling device according to the invention for a clutch or a clutch transmission can be applied to all drive trains of vehicles, eg. B. of motor vehicles or commercial vehicles, especially passenger cars and trucks, or be applied to all torque transmission devices. Preferably, the coupling device according to the invention is designed as a wet multiple clutch device, in particular as a radial dual clutch device, for a small vehicle.

The lamellae basket according to the invention comprises a first lamella receptacle for a first friction pack of the multiple clutch and a second louver receptacle for a second friction pack of the multiple clutch, the first louver receptacle and the second louver receptacle of the lamella basket are integrally, materially integral, simple or integral. - Furthermore, a pressure ring of the slat basket with the slat basket in one piece, material in one piece, be simple or integral. In this case, the pressure ring may be formed on an inner longitudinal end edge of the second lamella receptacle or of the lamella basket, which lies axially opposite a web of a U-profile of the lamella basket or the lamella basket. Of course, the pressure ring can also be formed on a radially opposite longitudinal end edge of the fin basket.

Under a one-piece lamellar basket is z. B an integrally held together, connected or trained lamellar basket, which is not easy separable by hand or separable but separable separable only by means of a tool. Here, the slat basket can be made of a single piece of origin. Under a materially integral lamellar basket z. B to understand a materially integrally held together or trained lamellar basket, which can not be separated without damaging the slats basket. The entire slat basket is held together by a strong material connection. Under a simple slat basket is z. B to understand a lamellar basket, which is also made of a single piece of origin. And under an integral lamellar basket is z. B to understand a lamellar basket whose origin piece is in turn integrally formed. - This is analogous to the pressure ring and the lamellar basket applicable.

The lamella basket is adapted to produce an axially displaceable rotationally fixed connection between friction plates and an input or output shaft. The slat basket proposed here has the first and the second slat receptacle, wherein the first slat receptacle for the first friction pack and the second slat receptacle for the second friction pack are arranged, or vice versa. D. h., That between the recordable in the respective slats recording of the lamellar basket friction plates, z. B. outer plates, opposite friction plates, z. B. inner plates, in a respective other disc carrier, z. B. an inner disc carrier, are added, or vice versa.

These opposing friction plates are neither axially nor rotationally connected to the disc basket described here, but they are alone connected via a frictional connection with the recorded in a respective lamellae of the lamellae friction plates such that a torque of the lamellar basket in the relevant, radially opposite lamellae recording of concerned other disk carrier is transferable, or vice versa. The pressing of the friction plates is via an actuating device with an actuating element, such. B. a pressure pot, switchable.

Here, the first and the second lamellae receptacle are integral, materially integral, simple or integral, so that they are rotationally fixed together. When using z. B. in a dual clutch of a motor vehicle, the slat basket proposed here may be used on an input side, d. H. be firmly connected to an output shaft of a drive unit. The friction plates of the first disc receptacle are connectable to a first output shaft (first Reibpaket) and the friction plates of the second disc receptacle are connected to a second output shaft (second Reibpaket), which with the two transmission shafts z. B. a dual-clutch transmission can be connected.

Due to the one-piece, material integral, simple or integral design of the lamellar basket is achieved that the lamella recordings are rotatably connected to each other and thus not consuming (pre-) must be mounted together. At the same time, the production of the lamellar basket is cost-effective, because the lamella receptacles can be manufactured in one piece and in a common manufacturing process substantially simultaneously. This concerns in the consequence Of course, a (multiple / double) coupling device, a clutch, etc.

According to one embodiment of the slat basket, the first slat receptacle and the second slat receptacle or the slat basket in the circular segment has a U-profile. The lamellar basket is essentially rotationally or rotationally symmetrical, so that a torque transmission can be transmitted unbalance-free. Here it is now proposed to make the first and second lamellar receptacle such that the substantially (cut hollow) annular lamellar basket has a U-profile in a segmental section, ie a circular segment. In a sectional view of rotating elements in a conventional technical drawing, the first lamellae receptacle, the second lamellae receptacle and the web can thus be recognized as a "U".

In other words, the U-profile is a sufficient segment of the lamellae basket, which forms the first lamella receptacle and the second lamella receptacle by a radius spaced from a rotation center (rotation axis) radius as a rotation body. The opening of the U-profile is preferably in the axial direction, so in a conventional technical drawing with horizontal (horizontal) axis of rotation, the U-profile is shown lying. This structure is easy to manufacture and particularly suitable for a space-saving design of a multiple clutch.

The lamellae basket may have an extending in the circumferential direction of the lamella basket or the multiple coupling, axially and radially lying extending U-profile. Furthermore, the lamellae basket can have a double U-profile in substantially all the axial planes of the lamella basket or the multiple coupling, wherein the two U-profiles are arranged substantially mirror-symmetrically with respect to the axis of rotation. Furthermore, the lamellar basket is formed mainly or substantially as a half-torus with mainly or substantially U-shaped generatrix.

According to one embodiment of the lamellae basket, the first lamella seat is arranged in the interior of the U-profile or of the lamella basket, and the second lamella seat is arranged on the outside of the U-profile or on the lamella basket. In this embodiment of the slat basket, a space which is defined by the U-profile, well used. For example, the first louver receptacle on the outer circumference of the U-profile inside the U-profile can be arranged and the corresponding inner disk carrier is correspondingly arranged on the opposite wall of the U-profile (spaced and unconnected). An external arrangement of the first lamella receptacle is also possible. The second lamella receptacle can be arranged on the outside of the U-profile, d. H. at the inner radius or at the outer radius of the lamella basket. Preferably, the second lamella receptacle is located on the inner radius of the U-profile.

In such an arrangement, the U-profile can be designed small and in a dual clutch, the input side friction plates, which are permanently rotated, located on each outer circumference, so that their higher inertia by a larger radius for smoothing a drive torque via an input shaft contributes and the inertia is not detrimental to changing rotational speeds of the output shafts. At the same time, the U-profile can be made small, so that a stability and rigidity of the U-profile or the lamella basket is high.

The outer, first lamella receptacle can be radially inward in the lamellar basket and the inner, second lamellar receptacle can be radially inwardly provided on the lamellar basket, in particular formed. be. This and also in the above embodiments, together with a coupling connection (see below) results in a lamellae basket for a double plate carrier, in particular a double outer plate carrier. - Furthermore, at least one of the lamellar recordings may be formed as a toothing, wherein the toothing is preferably formed by cold deformation of the lamella receptacle. A toothing is particularly suitable for slidably receiving friction plates and at the same time rotationally fixed. In this case, the toothing is preferably formed as a deformation of the (lamellar basket) material and not as a toothed toothing. In particular, the toothing is formed by a cold forming, so that the teeth can be produced inexpensively.

According to one embodiment of the lamellae basket, the two lamellae holders are produced by a common cold forming process when the U-profile or lamella basket is produced. In this embodiment, the lamellar recordings do not have to be incorporated later in the U-profile, but can be co-produced in the cold forming process. For example, the lamellar recordings can each be formed as a toothing, which are pressed into the (lamella basket) material when the U-profile is produced.

Preferably, the slat basket is made of a metal sheet. By manufacturing the lamellar basket made of sheet metal advantageous favorable manufacturing processes such as deep drawing and other cold forming operations can be used. In addition, the toothing may be formed by the formation of waves in the material, which produces a material-friendly and rigid teeth. In addition, such a corrugated toothing in the U-profile of the lamellar basket the lamellar basket stabilized overall. Furthermore, such a slat basket also z. B. forged, however, such high strengths are not required for many applications.

The disk carrier according to the invention, in particular the outer disk carrier according to the invention, has a disk basket according to the invention. The disk carrier or the outer disk carrier may comprise a coupling connection for transmitting a torque to the first and second disk receptacle, wherein the coupling connection is a separate component and is fixedly connected to the first and second disk receptacle or the disk basket (welding, Nietverbidnung etc.). , The coupling connection proposed herein bridges a radial distance between an input shaft and the first and second louver receptacles, so that a desired radius (range) is achieved for transmitting a desired torque. If necessary, an output shaft can also be used instead of an input shaft.

Here, in contrast to known arrangements, the coupling connection is not formed with a lamellae recording, but this is only later mounted with two lamellae recordings (lamellar basket). The assembly can be done by welding, soldering, gluing or other cohesive connections, with a positive connection and / or a frictional connection (rivets) are possible. By a separate design of the coupling connection, both components can be designed separately and / or constructed for the different tasks, namely the torque transmission over a large radius and the torque transmission over a small distance to the friction plates, each.

For this purpose, a thickness of a material layer of the coupling connection can be greater in comparison with a thickness of a material layer of the lamella basket or a thickness of a material layer of the first lamella receptacle and / or the second lamella receptacle. Ie. conversely, that a thickness of a material layer of the lamellar basket or a thickness of a material layer of the first lamellae receptacle and / or the second lamellae receptacle may be smaller than a thickness of a material layer of the coupling connection. Ie. The coupling connection is preferably made of a reinforced sheet metal.

The method according to the invention comprises at least the following steps: forming a sheet metal blank in a ring shape, which is flat in the radial extent, and forming a U-shaped profile into the ring shape by cold forming, wherein during cold forming a first lamella receptacle and a second lamella receptacle are preferably formed at the same time. - First, a sheet metal blank is brought into a ring shape, for example by punching or lasing of a sheet raw material, so that the sheet material extends flat and in an annular shape. The sheet material thus forms an area in a plane of a radius of the ring. This annular sheet metal blank is placed on a mold and then embossed a U-profile, so that there is a U-profile in the circle segment (half-orbit with U-shaped generatrix).

In this case, the first lamella receptacle and the second lamella receptacle are preferably formed at the same time or, if appropriate, in a chronological order, wherein this preferably results in a corrugation in the outer diameter and / or in the inner diameter of the U-profile, which serves as a toothing for the eventual friction plates to be included. The formed by this method sheet metal blank is thus bent or bent axially on its inner circumference to one side by 90 ° and also bent or bent on the outer circumference in the same direction by 90 °. Preferably, the lamellar basket is produced by deep drawing, so that the sheet metal blank can be brought in a single step in a final form. Here, a pressure ring of the lamellar basket mitausgebildet, wherein the pressure ring is preferably formed at an inner longitudinal end edge of the second lamellar receptacle.

Subsequently, a coupling connection can be attached to the U-profile or the lamella basket. Ie. temporally after the manufacture of the lamellar basket, the lamellar basket is fastened to the coupling connection or coupling connection on the lamella basket. In this case, the lamella basket can be connected, in particular welded, to the coupling connection, at least in a materially bonded manner. Furthermore, the lamellae basket with the coupling connection can alternatively at least non-positively connected, in particular riveted, be.

The coupling device according to the invention, the torque transmission device according to the invention, the clutch according to the invention or the transmission according to the invention has a lamellae basket according to the invention and / or a plate carrier according to the invention. In this case, a lamella basket according to the invention of one / of the disk carrier can be produced by a method according to the invention. Preferably, the coupling device, the clutch or the transmission is designed as a double clutch device, a double clutch or a dual clutch transmission.

So z. B. a dual clutch according to the invention with an axis of rotation for releasably connecting an output shaft with a drive train at least the following components: Two Reibpakellen each having a plurality of friction plates, each in a Pressed state torque is transferable, and one / the lamellae basket for at least partially receiving the two friction packs, wherein preferably the coupling connection at the same time forms a wall portion of at least one hydraulic actuator for at least one of the Reibpakete. In this case, the lamellar basket can be constructed as described above and / or produced according to a method as described above.

The dual clutch is adapted to releasably transfer a torque from an output shaft, advantageously via a double shift transmission, and vice versa in a drive train. This is usually achieved by means of a respective friction pack, which in each case has a plurality of axially displaceable, generally rotationally fixed with the output shaft, friction disks which can be pressed against a corresponding number of opposing friction disks. As a result of the contact force results in a frictional force over the friction surfaces, which multiplied by the average radius of the friction surfaces results in a transmissible torque. The slat basket proposed here allows a space-saving and stable construction. - With a slat basket or plate carrier proposed here and the method for producing a slat basket or slat carrier a cost-effective construction of a multiple clutch is possible, at the same time a good application of force is implemented on the friction plates of Reibpakellen.

The invention is applicable to a motor vehicle, which has a drive unit with an output shaft, a drive train with a clutch according to the invention, for. B. a double clutch according to the invention, according to the above description. Most motor vehicles today have a front-wheel drive and therefore preferably arrange the drive unit, for example an internal combustion engine or an electric motor, in front of a driver's cab and transversely to the main driving direction. The space is especially small in such an arrangement and it is therefore advantageous to use a friction clutch small size.

A space situation is exacerbated in passenger cars of small car class z. B. according to European classification. The units used in a passenger car of the small car class are not significantly reduced compared to passenger cars larger car classes. Nevertheless, the available space for small cars is significantly smaller. With the double clutch proposed here, a construction of small size and at the same time cost-effective production is possible.

Passenger cars are classified according to vehicle class according to, for example, size, price, weight, power, and this definition is subject to constant change according to the needs of the market. Vehicles classified in European Classification Small cars and microcars correspond to the Subcompact Car category in the US market and to the City Car class in the UK market. Examples of the micro car class are a Volkswagen Fox or a Renault Twingo. Examples of the small car class are an Alfa Romeo Mito, a Volkswagen Polo, a Ford Fiesta or a Renault Clio.
