Technical Field

The invention relates to a method for producing a clutch device.

Background

Clutch devices having a first clutch unit and a second clutch unit are known. The first clutch unit has a first clutch input, a first clutch plate set, and a first clutch output. The second clutch unit has a second clutch input, a second clutch plate set, and a second clutch output. The first clutch input is connected to a first transmission input shaft of the transmission in a torque-locking manner. The second clutch output can be connected to a second transmission input shaft of the transmission in a torque-locking manner. The first clutch plate set is used for providing friction locking and is used for connecting the first clutch input part and the first clutch output part in a torque locking mode. The second clutch plate set is used for providing second friction locking and connecting the second clutch input part and the second clutch output part in a torque locking mode. The two clutch outputs are usually configured differently from one another. This requires different tools for producing the respective clutch outputs.

Disclosure of Invention

The object of the present invention is to provide a clutch device which is particularly cost-effective and can be produced in a simple manner.

This object is achieved by means of a clutch device as described below.

According to the invention, it is proposed that an improved clutch device which is mounted so as to be rotatable about an axis of rotation and which has a first clutch unit and a second clutch unit can be produced particularly cost-effectively. The first clutch unit includes a first clutch output having a first clutch plate carrier and a first clutch plate set having at least one first driven side friction plate. The first driven-side friction plate is coupled with the first receiving portion of the first clutch plate carrier in a torque-locking manner. The second clutch unit includes a second clutch output having a second clutch plate carrier and a second clutch plate set having at least one second driven side friction plate. The second driven-side friction plate is coupled with the second receiving portion of the second clutch plate carrier in a torque-locking manner. The first receiving part is at least partially identical to the second receiving part.

This configuration has the advantage that the number of tools necessary for production is reduced when producing the first and second driven-side clutch plate carriers, so that the production costs of the clutch device as a whole are reduced. Thus, the cost expenditure for producing the clutch device can be reduced thereby.

In a further embodiment, the first clutch plate carrier and/or the second clutch plate carrier is designed as an inner clutch plate carrier or as an outer clutch plate carrier.

In a further embodiment, the first clutch plate carrier has a first carrier section. The first bracket section is coupled with the first receiver and is configured to at least partially carry the first receiver. The second clutch plate carrier has a second carrier section. The second bracket section is configured to at least partially carry a second receiver. The second carrier section is of identical design to the first carrier section. This further reduces the number of tools required for the manufacture of the clutch device.

In another embodiment, the second clutch plate carrier comprises a carrier element. The carrier element is connected to the second carrier section. The second carrier element is preferably arranged radially inside and/or radially outside with respect to the carrier section.

In a further embodiment, the first receiving part has a first toothing and the second receiving part has a second toothing. The first tooth is of identical design to the second tooth.

In another embodiment, the first clutch unit has a first clutch input and the second clutch unit has a second clutch input. The first clutch plate set includes at least one first drive side friction plate and the second clutch plate set includes at least one second drive side friction plate. The first drive-side friction disk is coupled with the first clutch input in a torque-locking manner, and the second drive-side friction disk is coupled with the second clutch input in a torque-locking manner.

According to the invention, it is proposed that the production costs for producing the clutch device can be reduced by providing a first output part for producing the first clutch plate carrier and a second output part for producing the second clutch plate carrier, wherein the first receptacle is formed into the first output part by means of a first tool and the second receptacle is formed into the second output part by means of the first tool.

In a further embodiment, the first carrier section is formed on the first output part and the first carrier section is formed on the second output part by a further tool, wherein at least one predetermined section of the first carrier section of the second output part is separated to form the second carrier section, wherein the second carrier section is connected with a carrier element in a torque-locking manner.

Detailed Description

Fig. 1 shows a half-longitudinal section of the clutch device 10. The clutch device 10 can be rotatably supported about a rotational axis 15. The clutch device 10 has an input side 20. The input side 20 can be connected to a drive motor, for example a reciprocating piston engine, in a torque-locked manner. The clutch device 10 includes a first clutch unit 25 and a second clutch unit 30. The first clutch unit 25 has a first clutch input 35 and a first clutch output 40. The second clutch unit 30 has a second clutch input 45 and a second clutch output 50. The first clutch output 40 can be connected in a torque-locking manner to the first transmission input shaft 55. The second clutch output 50 is connected to the second transmission input shaft 60 in a torque-locking manner.

The first clutch output 40 includes a first driven side clutch plate carrier 65 and a first hub 70. The first clutch disk carrier 65 on the output side is arranged radially outside the first hub 70 and is connected to the first hub 70 in a torque-locking manner. The first hub 70 provides a torque-locked connection to the first transmission input shaft 55. The first clutch input 35 of the first clutch unit 25 further comprises a first drive side clutch plate carrier 75. The first drive side clutch plate carrier 75 and the first driven side clutch plate carrier 65 form an annular gap 80. In the annular gap 80, the first clutch unit 25 has a first clutch plate pack 85. The first clutch plate pack 85 includes at least one first driving side friction plate 90 and at least one first driven side friction plate 95. The first driven-side friction plate 95 is implemented as a friction lining in this embodiment, and the first driving-side friction plate 90 is implemented as a friction plate without a lining layer. Of course, other configurations of

first friction plates

90,95 are also contemplated. The

first friction plates

90,95 are alternately arranged in a stacked manner. The first drive-side friction disk 90 is connected in a torque-locking manner and axially displaceably to the first drive-side clutch disk carrier 75. The first driven-side friction plate 95 is connected to the first driven-side clutch plate carrier 65 in a torque-locking manner and is axially movable. The first clutch unit 25 also has a first actuating device 100.

The first operating device 100 is used to provide a first operating force acting in the axial direction. The

first friction plates

90,95 of the first clutch disk pack 85 are pressed axially against one another by means of a first actuating force, as a result of which the

first friction plates

90,95 are brought into operative connection and a friction lock is produced between them, which friction lock connects the first drive-side clutch disk carrier 75 in a torque-locking manner with the first driven-side clutch disk carrier 65. If the first actuating device 100 is actuated, the torque from the drive motor is conducted from the input side 20 into the clutch disk carrier 75 of the first drive side. From there, torque is transmitted to the first drive side friction plate 90, and from the first drive side friction plate to the first driven side friction plate 95. The first driven-side friction plate 95 transmits the torque to the first drive-side clutch plate carrier 75, which in turn continues to transmit the torque to the first hub 70. The torque is further conducted from the clutch device 10 via the first hub 70 into the first transmission input shaft 55.

The clutch plate carrier 65 on the first driven side comprises a first receptacle 105 and a first carrier section 110. The first carrier section 110 extends substantially in the radial direction and is connected to the first hub 70 on the radially inner side. The first carrier section 110 is connected radially on the outside to the first receptacle 105. The first receiving portion 105 has a first tooth 115. The first tooth system serves to provide a torque-locking connection to the first driven-side friction plate 95 and to support the first driven-side friction plate 95. The first driven-side friction plate 95 is coupled to the first receiving portion 105 so as to be movable in the axial direction by the first tooth portion 115. In this embodiment, the first driven-side clutch plate holder 65 is configured as an inner clutch plate holder, i.e., the first driven-side friction plate 95 is arranged radially outward with respect to the first receiving portion 105. Of course, it is also conceivable for the first driven-side clutch disk carrier 65 to be configured as an outer clutch disk carrier, i.e. for the first driven-side friction disk 95 to be arranged radially inside with respect to the first receptacle 105.

The second clutch input 45 includes a second drive side clutch plate carrier 120. The second clutch output 50 includes a second hub 125 and a second driven-side clutch plate carrier 130. The second drive-side clutch plate carrier 120 is of substantially cylindrical design and forms an axial extension of the first drive-side clutch plate carrier 75. The second drive-side clutch plate carrier 120 and the second driven-side clutch plate carrier 130 form a second annular gap 135, in which a second clutch plate stack 140 of the second clutch unit 30 is arranged. In this embodiment, the second drive-side clutch plate carrier 120 is formed integrally and of the same material as the first drive-side clutch plate carrier 75.

The second clutch plate set 140 includes at least one second driving side friction plate 145 and at least one second driven side friction plate 150. The second driven side friction plate 150 is configured as a friction lining in this embodiment, while the second driving side friction plate 145 is configured as a friction plate without a lining, on the contrary. Other configurations of the second friction plates 145,150 are of course contemplated. The second friction plates 145,150 are alternately arranged in a stacked manner. In this case, the second drive-side friction disk 145 is connected to the second drive-side clutch disk carrier 120 in a torque-locking manner, but is displaceable in the axial direction. The second driven-side friction disk 150 is connected to the second driven-side clutch disk carrier 130 in a torque-locking manner, but is displaceable in the axial direction.

The second driven-side clutch plate carrier 130 comprises a second receiving portion 155, which extends substantially in the axial direction. The second receptacle 155 is axially engaged, and the second driven-side clutch plate carrier 130 has a second carrier section 160. Radially on the inside on the second carrier section 160, the clutch plate carrier 130 on the second driven side has a carrier element 165. The carrier member 165 is formed integrally and materially integrally with the second hub 125, which provides a torque-locking connection to the second transmission input shaft 60. The second receiving portion 155 includes a second tooth portion 175. The second toothing 175 serves to provide a torque-locking connection to the second driven-side friction plate 150, while ensuring axial displaceability of the second driven-side friction plate 150. In order to reduce the manufacturing cost of the clutch device 10, in this embodiment, the first receiving portion 105 is made by the same tool as the second receiving portion 155. For this reason, the first receiving portion 105 is configured identically to the second receiving portion 155. Of course, it is also conceivable for the second receptacle 155 to be constructed only in sections identically to the first receptacle 105. This is conceivable, for example, if the first tooth 115 and the second tooth 175, although of identical design, have different axial lengths, for example, of the first receptacle 105 and the second receptacle 155. Other configurations of the receiving portions 105,155 are also contemplated.

The second carrier section 160 is formed integrally and materially in line with the second receptacle 155 and carries the second receptacle 155. The second carrier section 160 is shorter in the radial direction than the first carrier section 110. In this embodiment, however, the second carrier section 160 is of the same design as a region of the first carrier section 110. In this way, the production costs of the clutch device 10 can likewise be reduced. It is also conceivable for the second carrier section 160 to be of identical construction to the first carrier section 110.

The second carrier section 160 is connected radially on the inside by a connection 180 with a torque-locking connection to the carrier element 165. For example, the connection 180 can be designed as a material-locking connection, in particular as a welded connection. Of course, it is also contemplated that the connection 180 may be configured in other ways.

The second clutch unit 30 also has a second actuating device 185. The second manipulation device 185 is used to provide a second manipulation force. When the first actuating device 100 is normally not actuated and therefore the first clutch unit 25 is open, the second actuating device 185 is actuated. In order to prevent the actuation of the first clutch plate set 85 by the second actuation device 185, a decoupling device 190 is provided in the axial direction between the first clutch plate set 85 and the second clutch plate set 140. The release device 190 is connected to the clutch plate carrier 75 on the first drive side. The release device 190 serves to guide the second actuating force from the second clutch disk pack 140 into the first drive-side clutch disk carrier 120. The provision of the decoupling device 190 allows the two clutch disk sets 85,140 to be arranged at the same height in the radial direction, as a result of which the clutch device 10 has a particularly small installation space requirement in the radial direction.

If the second actuating device 185 is activated and provides a second actuating force acting in the axial direction, the second drive-side friction disk 145 and the second driven-side friction disk 150 are pressed against one another, so that they are brought into operative connection with one another and a friction lock is produced, which connects the second drive-side clutch disk carrier 120 with the second driven-side clutch disk carrier 130 in a torque-locking manner. In this state of the second clutch unit 30, the torque continues to be transmitted via the input side 20 and the first drive-side clutch plate carrier 75 to the second drive-side clutch plate carrier 120. The second drive side clutch plate carrier 120 transmits torque to the second drive side friction plate 145. Torque is transmitted from the second driven-side friction plate 150 to the second tooth 175 and thus to the second receiving portion 155 by frictional engagement between the second drive-side friction plate 145 and the second driven-side friction plate 150. The second receptacle 155 conducts the torque further via the second carrier section 160 to the carrier element 165 and the carrier element conducts the torque further to the second hub 125. Second hub 125 transfers the torque to second transmission input shaft 60.

Fig. 2 shows a half-longitudinal section of the output section 200 of the clutch plate carrier 75,130 on the first or second driven side shown in fig. 1 of the clutch device 10 shown in fig. 1 after a first machining step. Fig. 3 shows a half longitudinal section of the output section 200 after the second processing step. Fig. 4 shows a half longitudinal section of the output section 200 shown in fig. 3 after the third machining step, and fig. 5 shows a partial half longitudinal section of the clutch plate holder 130 on the second driven side shown in fig. 1. Fig. 6 shows a flowchart of a method for producing the driven-side clutch plate carrier 65,130 shown in fig. 1 and 5.

In a first method step 300, the first output section 200 or the second output section 201 is formed from a flat plate by means of a press-bending tool 204 in a press-bending process. The first carrier section 110 is formed in the two output parts 200,201, and the sections for the teeth 115,175 are bent relative to the first carrier section 110 in such a way that the sections for the teeth extend substantially in the axial direction. The first driven-side clutch plate carrier 65 is formed by the first output part 200, and the second driven-side clutch plate carrier 130 is formed by the second output part 201.

In a second method step 305, the receiving part 105,155 is shaped by means of the first tool 205 and the tooth 115,175 is introduced into the output part 200,201, for example by means of a rolling process. After the second method step 305, the production of the first clutch plate carrier 75 is completed. After the second method step 305, the two output parts 200,201 are identically designed, wherein both output parts 200,201 can be used as clutch plate carriers 65 on the first output side.

After the second method step 305, in a third method step 310 following the second method step 305, the first output part 200 is used as the first driven-side clutch disk carrier 65 and is connected radially on the inside with the first hub 70, for example, by means of a welding process in a torque-locking manner.

The production of the second driven-side clutch plate carrier 130 is continued by a fourth method step 315 following the second method step 305.

In a fourth method step 315, as shown in fig. 4, the radially inner, predetermined section 215 of the carrier sections 110,160 of the second output part 201 is separated by means of the second tool 210, and the second carrier section 160 is thereby molded from the first carrier section 110. It is pointed out in this connection that the separation of the predetermined section 215 by means of the second tool 210 for producing the second carrier section 160 can of course be dispensed with, and the second carrier section 160 is constructed identically to the first carrier section 110. Thus, the clutch plate holders 65,130 on the first and second driven sides can be replaced with each other.

In a fifth method step 320, which follows the fourth method step 315, the second carrier section 160 is connected to the separately produced carrier element 165 radially on the inside in a torque-locking manner by means of the connection 180. Of course, it is also conceivable for the second carrier element 165 to be arranged radially on the outside on the second carrier section 160 and to be connected radially on the outside on the carrier section 160 to the second carrier section 160 by means of the connection 180.

The advantage of the above-described configuration and method for producing the driven-side clutch plate carrier 65,130 is that, in particular in a clutch device 10 having radially overlapping clutch plate sets 85,140, the number of tools 204,205,210 for producing the driven-side clutch plate carrier 65,130 can be reduced, thereby reducing the production costs of the clutch device 10 overall compared to conventional clutch devices. Furthermore, a high component quality can also be ensured by using the same tool 204,205,210 for the two clutch disk carriers 65,130 on the output side, so that reworking is reduced or not required. It is particularly advantageous if the driven-side clutch disk carrier 65,130 is of substantially identical design, so that, in addition to the reworking in the production of the driven-side clutch disk carrier 65,130, they can also be interchanged in the installed state.
