Definitions
- the invention relates to a carrier for friction elements of a clutch.
- the invention relates to a carrier for friction elements of different clutches of a double clutch.
- a powertrain such as a motor vehicle, includes a drive motor and a dual clutch transmission that includes a dual clutch with two clutches and a transmission. Input sides of both clutches are connected to an output shaft of the drive motor. Output shafts of the clutches are connected to different transmission shafts, which act on different gear pairs on a common output shaft of the transmission. It is usually always only one of the clutches closed and the other opened. A gear change can be done by opening the closed and simultaneous closing of the opened clutch.
- the dual clutch may be of the radial type, wherein the two clutches are radially offset, so that an axial space can be small.
- Each clutch usually comprises a first friction element, which is torque-connected to the input side, and a second friction element, which is torque-connected to the output side. If the friction elements are pressed against each other axially, then the clutch closes and a torque can be transmitted between the input side and the output side. In order to keep the friction elements axially displaceable with respect to their associated sides, they are usually by means of a toothing with these engaged.
- the input side comprises a carrier element with an internal toothing and the output side a carrier element with an external toothing or vice versa.
- Carrier elements of the two clutches which are each assigned to an input side, are connected in a torque-locking manner to form a common input side.
- Different torque-resistant connections can be used.
- the carrier elements can be welded or riveted together.
- the support elements can be inserted into each other and secured with axial securing elements.
- the associated joining processes are relatively expensive, so that a carrier comprising both carrier elements can be expensive to manufacture.
- Au- a connecting portion between the support members may be exposed to varying loads in the circumferential direction, so that the likelihood of fatigue strength of the wearer may be reduced.
- the invention has for its object to provide an improved support for friction elements of a radial double clutch.
- the carrier should be simple and inexpensive to manufacture.
- a connection between carrier elements of the carrier should also withstand the expected operating loads when using the carrier in a double clutch.
- a carrier according to the invention for friction elements of a radial double clutch with an axis of rotation comprises a radially inner carrier element and a radially outer carrier element.
- the inner support member has an axial portion which carries an inner toothing and an outer toothing
- the outer support member has a radial portion with an internal toothing, which engages in the outer toothing of the inner support member.
- the outer support member is held by means of press fit axially on the inner support member.
- the transmission of forces acting in the circumferential direction between the inner and the outer carrier element can be done mainly by means of the toothing.
- the interference fit between the inner and the outer support member ensures that the connection is free of play, so that changing loads, especially in the circumferential direction, do not compromise the strength of the connection between the support elements.
- axial loads of one of the support elements for example by an actuating mechanism, the axially compressed friction elements can be well absorbed by the press fit.
- the assembly of the carrier elements to each other can be done easily and inexpensively. For mounting, only an axial pressing tool may be required.
- the press connection can be detachable, so that, for example, in case of damage, the support elements can be separated from each other.
- the support elements can be produced from a sheet metal falling tool, that is, that the support elements can be processed in a single step so that they are ready from the processing device fall or can be removed from this.
- Such production can be accompanied by price advantages.
- the press fit is formed in the region of the intermeshing teeth.
- the tip circle of the inner toothing of the outer support member and the root circle of the outer toothing of the inner support member may be made with a predetermined overlap.
- the tip circle of the external toothing of the inner carrier element can be matched to the root circle of the internal toothing of the outer carrier element.
- the covers are preferably sufficiently large to ensure a secure fit of the two support members to each other, but at the same time also sufficiently small to hold a required axial pressing force for mounting the support members together in a manageable area.
- the coverage should not be so large that one of the teeth, in particular the toothing of the inner support member, can be damaged during assembly.
- the axial portion of the inner support member comprises a rotating around the axis of rotation plate forming the internal toothing and the external toothing.
- the internal teeth and the external teeth can be produced in one operation.
- the inner support member may be pot-shaped and be prepared, for example, in a thermoforming process.
- the inner support member may have a radial portion extending radially inward from the axial portion, the radial portion being configured to transmit torque to both support members.
- the inner support member may represent an input side of a clutch or dual clutch. The introduction of a torque in the carrier can thus preferably take place close to the axis of rotation, so that a simple and space-saving connection to an output shaft of a drive motor can be formed.
- the internal toothing of the radially inner support member is adapted to engage in external toothing of a friction element, wherein an axial region in which the friction element is located with respect to the inner support member, axially offset from a region in which the support members press-fit against each other is.
- a holding element may be provided which extends in the region of the adjoining carrier elements, wherein the holding element comprises two radial sections.
- the first portion extends radially inwardly and abuts a first axial side of the inner support member while the second portion extends radially outward and abuts a second axial side of the outer support member.
- the holding element By means of the holding element can be ensured that the carrier elements are positioned axially in a predetermined manner to each other.
- a pressing-in process of the inner into the outer carrier element can then be ended when the radial sections of the holding element bear against the associated carrier elements.
- the retaining element can help to prevent an axial displacement of the carrier elements against each other due to axial loads, for example during the axial compression of friction elements.
- the holding element can forward axially acting on the outer support member forces to the inner support member without jeopardizing the strength of the press connection.
- one of the radial sections is circumferentially formed around the axis of rotation.
- a large axial contact surface can be provided and the retaining element can be produced from a disk-shaped component.
- an axial recess for an axial portion of the holding element is provided on one of the carrier elements in the region of the intermeshing teeth, which connects the two radial sections with each other.
- radial portion of one or more axial portions may be provided, which connects the circumferential radial portion with a number corresponding to the number of axial portions of the radial sections. It can be chosen a small number of axial sections, so that only a few axial recesses must be introduced on one of the support elements, which can benefit a resilience of the connection between the support members.
- a dual clutch according to the invention comprises two clutches, each adapted to selectively transmit torque from an input side to an output side, the carrier described above comprising the input sides of both clutches.
- the double clutch can be constructed easily, inexpensively and axially compact.
