Description

[0001] The invention relates to a pressure line for a pressure-operated actuation system, a modular system for the assembly of a pressure-operated actuation system, a method for the assembly of a pressure-operated actuation system and a method for the disassembly of a pressure-operated actuation system, with the aid of which a pressure-operated actuation system for actuating a clutch, in particular a friction clutch, of a motor vehicle can be operated and assembled or disassembled with the clutch bell.

[0002] It is known to screw a pressure-operated actuating cylinder of an actuating system, with which a pressure plate of a friction clutch of a motor vehicle can be hydraulically displaced, to a clutch bell housing. A pressure line is connected to the actuating cylinder, which can connect the actuating cylinder located inside the clutch bell housing to a pressure source located outside the clutch bell housing via a supply opening in the clutch bell housing. When assembling the actuating system, it is necessary to align and connect a component located inside the clutch bell housing and a component located outside the clutch bell housing, making assembly difficult and time-consuming. Furthermore, it is difficult and time-consuming to subsequently disassemble the actuating system.Known prior art is disclosed in DE 197 46 537 A1, DE 10 2008 053 ​​400 A1, DE 10 2008 060 585 A1 and US 4 624 290 A.

[0003] It is the object of the invention to show measures that enable a pressure-operated actuation system for actuating a clutch of a motor vehicle with little assembly and / or disassembly effort.

[0004] The object is achieved according to the invention by a pressure line having the features of claim 1, a pressure line having the features of claim 5, an actuation system having the features of claim 6, a modular system having the features of claim 7, a method for assembling a pressure-operated actuation system having the features of claim 8 and a method for disassembling a pressure-operated actuation system having the features of claim 10. Preferred embodiments of the invention are specified in the subclaims, which can each represent an aspect of the invention individually or in combination.

[0005] According to the invention, a pressure line for a pressure-operated actuation system for actuating a clutch is provided with a supply line that can be connected to the actuation system, in particular a substantially dimensionally stable angle adapter, for supplying a pressure medium into an actuation cylinder of the actuation system, a holding sleeve that is rotatably connected to the supply line via a locking device for rotatably fastening in a supply opening of a clutch bell, wherein the locking device blocks a lateral movement of the supply line relative to the holding sleeve in a closed angular position of the holding sleeve to the supply line and allows the lateral movement of the supply line relative to the holding sleeve in an open angular position of the holding sleeve to the supply line, and a connection adapter that projects through the holding sleeve into the supply line for penetrating the clutch bell via the supply opening,wherein the connection adapter has a locking means for locking a rotation of the holding sleeve from the closed angle position to the open angle position.,

[0006] The retaining sleeve, which can be rotated into the supply opening of the clutch bell housing, makes it possible to pre-assemble an actuating cylinder of the actuating system, particularly designed as a pressure cylinder, with the supply line and connect it to the clutch bell housing as a single structural unit. The actuating cylinder can initially be moved past protruding parts of the clutch bell housing at a radial distance from a centerline of the retaining sleeve thanks to an appropriate supply line geometry. After the retaining sleeve has been attached to the clutch bell housing, it can be pivoted into a designated end position by rotating it about an axis of rotation coinciding with the centerline of the sleeve, where it can be secured to the clutch bell housing. This enables simple and quick installation of the actuating system within the clutch bell housing.The connection adapter can be attached to the supply line from outside the clutch bell housing in order to connect a pressure source provided outside the clutch. The connection adapter can also be attached much later, in particular at a time when the clutch is already completely installed and in particular coupled to a drive shaft of a motor vehicle engine and to at least one transmission input shaft of a motor vehicle transmission. The actuating cylinder can in particular be annular and, in the installed state, surround in particular a transmission input shaft projecting into the clutch. In this state, the actuating cylinder cannot necessarily be pivoted by rotating the supply line about an axis of rotation coincident with the center line of the retaining sleeve in order to dismantle the actuating cylinder, for example for repair.Instead, it is possible to loosen the connection adapter until the retaining sleeve is no longer locked and can be rotated into its open-angle position. This allows the actuating cylinder, together with the supply line, to be removed by a lateral movement relative to the retaining sleeve, in particular in an axial direction of the clutch, essentially parallel to the clutch axis of rotation. This enables simple and quick removal of the actuating system from the clutch bell housing. The actuating system can be easily installed by a pivoting movement in the closed-angle position of the retaining sleeve, and after slightly loosening the connection adapter in the open-angle position, it can be easily removed by a lateral movement. This enables a pressure-operated actuating system for actuating a motor vehicle clutch with minimal assembly and / or disassembly effort.

[0007] The supply line can be made, in particular, from a dimensionally stable and / or inflexible material, for example, a thermoplastic. The supply line can be designed as an angle adapter, which in particular enables a deflection of the pressure medium, in particular hydraulic oil, by, for example, 90° ± 10°. The supply line can open into the actuating system, in particular an actuating cylinder of the actuating system, in a radial direction extending radially to a designated axis of rotation of the clutch or substantially parallel to this radial direction. The supply line can be detachably or permanently connected to the actuating system. The actuating system can be designed, in particular, as an engaging and / or disengaging device of a friction clutch, with the aid of which a pressure plate can be displaced between the pressure plate and the counterplate for frictionally pressing a clutch disc.The actuation system comprises, in particular, at least one annular actuation cylinder, wherein the actuation system preferably comprises two substantially coaxially arranged annular actuation cylinders (“concentric slave cylinders”, “CSC”) for a dual clutch. The clutch actuated by the actuation system is designed, in particular, for coupling a drive shaft, in particular a crankshaft, of a motor vehicle engine to at least one transmission input shaft of a motor vehicle transmission. In the assembled state, the at least one transmission input shaft can, in particular, protrude through the actuation cylinder of the actuation system in order to be able to connect a clutch disc to the transmission input shaft in a rotationally fixed manner.

[0008] Preferably, the retaining sleeve can encompass the supply line radially outwardly so that the supply line can be partially inserted into the retaining sleeve. The retaining sleeve and the supply line are in particular centered with one another. The retaining sleeve is thus accessible from the outside and can thus be easily rotated by hand between the opening angle position and the closing angle position. The opening angle position and / or the closing angle position is defined in particular by a respective stop which blocks excessive rotation of the retaining sleeve beyond the opening angle position or the closing angle position. Preferably, the locking device of the retaining sleeve can extend radially outside the supply line in a partial area.The locking device can thus, in particular, form a locking projection projecting in the axial direction, which, in the closed-angle position, securely retains the supply line between the locking projection and the clutch bell housing in the clutch bell housing. The circumferential extension of the locking projection is, in particular, selected such that an opening is created through which the supply line can be moved lateralward in the open-angle position.

[0009] The retaining sleeve is rotatable between the opening angle position and the closing angle position both relative to the supply line and relative to the clutch bell housing if the rotation of the retaining sleeve is not blocked by the locking means of the connection adapter. In particular, the connection adapter can be inserted into the retaining sleeve, whereby the connection adapter can preferably extend as far as the supply line. The connection adapter can, for example, be partially inserted into the supply line, whereby the connection adapter can be centered in particular with the supply line. In particular, the connection adapter can be connected to the supply line in a rotationally fixed manner. When the connection adapter is separated from the supply line, the retaining sleeve is rotatable.When the connection adapter is connected to the supply line at the specified maximum insertion depth, rotation of the retaining sleeve is blocked or at least significantly restricted by the locking means of the connection adapter. The locking means can lock relative rotation of the retaining sleeve, particularly by positive and / or frictional engagement.

[0010] In particular, the retaining sleeve has at least one latching hook to form a clip connection with the clutch bell, wherein the locking means of the connection adapter forms a locking stop pointing in the circumferential direction for the latching hook. The retaining sleeve can therefore be easily inserted into the supply opening of the clutch bell, in particular via at least two radially inwardly flexible latching hooks. The latching hooks can bear frictionally against the supply opening from the radially inward direction, while still allowing manual rotation of the retaining sleeve. When the connection adapter is connected to the supply line, the locking means can be inserted between two latching hooks following one another in the circumferential direction, so that when the retaining sleeve is rotated, the latching hooks can strike the respective locking stop, thereby blocking rotation of the retaining sleeve from the closed angle position to the open angle position.

[0011] The connection adapter preferably has a position fixing element, in particular a position fixing lug for contacting the clutch bell housing, for fixing the angular position of the connection adapter relative to the clutch bell housing. The connection adapter can thus be fixed in its angular position in such a way that, when an attempt is made to rotate the retaining sleeve from the closed angular position to the open angular position, the force acting on the locking means can be dissipated via the position fixing element without the connection adapter being able to rotate with the retaining sleeve. In particular, a position fixing lug protruding radially from the connection adapter is sufficient as the position fixing element; when an attempt is made to rotate the retaining sleeve from the closed angular position to the open angular position, this position fixing lug strikes the clutch bell housing but allows rotation in the opposite circumferential direction. This facilitates the assembly of the connection adapter.

[0012] Particularly preferably, the retaining sleeve blocks axial movement of the supply line relative to the retaining sleeve in the closed angular position. This can prevent the retaining sleeve from being inadvertently separated from the supply line during assembly of the actuation system in the clutch bell housing. For example, the supply line can have an at least partially circumferential groove into which a locking lug protruding radially inward from the locking attachment of the locking device can engage. Additionally or alternatively, the locking lug can form a partially circumferential groove with the rest of the retaining sleeve, into which a collar of the supply line protruding radially outward from the supply line can protrude. In the open angular position, the locking lug can be easily inserted into and / or moved out of the groove by the lateral movement of the supply line.

[0013] The invention further relates to a pressure line for a pressure-operated actuation system for actuating a clutch, with a supply line that can be connected to the actuation system, in particular a substantially dimensionally stable angle adapter, for supplying a pressure medium into an actuation cylinder of the actuation system, a holding sleeve that is rotatably connected to the supply line via a locking device for rotatably fastening in a supply opening of a clutch bell, wherein the locking device blocks a lateral movement of the supply line relative to the holding sleeve in a closed angular position of the holding sleeve to the supply line and allows the lateral movement of the supply line relative to the holding sleeve in an open angular position of the holding sleeve to the supply line, and a detachable plug inserted into the supply line for holding the holding sleeve, in particular by friction, in the closed angular position.The pressure line can be designed and further developed in particular as described above.

[0014] The plug can prevent dirt from entering the actuation system, in particular an actuation cylinder of the actuation system, during assembly. Furthermore, the retaining sleeve can be held in the closed angle position by the plug during assembly, thus preventing the retaining sleeve from being inadvertently separated from the supply line when the actuation system is being installed in the clutch bell housing. The plug can in particular have an extension in the radial direction so that the plug, in the inserted state, can be guided outwards through the supply opening of the clutch bell housing during assembly, so that the plug can be removed from outside the clutch bell housing. Once the retaining sleeve has been fastened in the supply opening of the clutch bell housing, the plug can be removed and replaced with the connection adapter.The actuation system can be easily mounted by a pivoting movement in the closed angle position of the retaining sleeve and can be easily dismantled by a lateral movement after a slight loosening of the connection adapter in the open angle position, so that a pressure-operated actuation system for actuating a clutch of a motor vehicle is possible with little assembly and / or disassembly effort.

[0015] The invention further relates to an actuating system for actuating a clutch, in particular for coupling a drive shaft of a motor vehicle engine to at least one transmission input shaft of a motor vehicle transmission, comprising a pressure-operated actuating cylinder for displacing a pressure plate of the clutch and a pressure line connected to the actuating cylinder, which can be designed and developed as described above, wherein the retaining sleeve runs eccentrically to the actuating cylinder. The actuating system can be easily assembled by a pivoting movement in the closed angular position of the retaining sleeve and, after slightly loosening the connection adapter in the open angular position, can be easily disassembled by a lateral movement, thus enabling a pressure-operated actuating system for actuating a clutch of a motor vehicle with minimal assembly and / or disassembly effort.

[0016] The invention further relates to a clutch for coupling a drive shaft of a motor vehicle engine to at least one transmission input shaft of a motor vehicle transmission, with a pressure plate that can be displaced relative to a counter-plate by means of an actuating system that can be designed and developed as described above, for frictionally pressing a clutch disc that can be connected to a transmission input shaft, and a clutch bell for at least partially covering the pressure plate, wherein the actuating cylinder of the actuating system is connected to the clutch bell.The actuation system can be easily mounted by a pivoting movement in the closed angle position of the retaining sleeve and can be easily dismantled by a lateral movement after a slight loosening of the connection adapter in the open angle position, so that a pressure-operated actuation system for actuating the coupling is possible with little assembly and / or disassembly effort.

[0017] The invention further relates to a modular system for the assembly of a pressure-operated actuation system for actuating a clutch, comprising a supply line connectable to the actuation system, in particular a substantially dimensionally stable angle adapter for supplying a pressure medium into an actuation cylinder of the actuation system, a retaining sleeve rotatably connectable to the supply line via a locking device for rotatably fastening in a supply opening of a clutch bell housing, wherein the locking device blocks a lateral movement of the supply line relative to the retaining sleeve in a closed angular position of the retaining sleeve to the supply line and allows the lateral movement of the supply line relative to the retaining sleeve in an open angular position of the retaining sleeve to the supply line, a connection adapter for penetrating the clutch bell housing via the supply opening through the retaining sleeve into the supply line,The connection adapter has a locking means for blocking rotation of the retaining sleeve from the closed-angle position to the open-angle position, and a plug that can be inserted into the supply line for holding the retaining sleeve in the closed-angle position, in particular by frictional engagement. In particular, a pressure line can be produced, which can be designed and developed as described above. Preferably, a pressure-operated actuation system for actuating a coupling can be produced with the aid of the modular system, which can be designed and developed as described above. With the aid of the modular system, the plug can be connected to the supply line before and during assembly of the pressure line or the actuation system, while the connection adapter is kept ready. After assembly, the plug can be removed and replaced with the connection adapter.In particular, to connect a pressure source via the connection adapter. The plug can be kept ready for later disassembly of the actuation system and / or reused as part of another appropriately designed modular system. The actuation system can be easily assembled by a pivoting movement in the closed angle position of the retaining sleeve and, after slightly loosening the connection adapter in the open angle position, easily disassembled by a lateral movement, thus enabling a pressure-operated actuation system for actuating a motor vehicle clutch with minimal assembly and / or disassembly effort.

[0018] The invention further relates to a method for assembling a pressure-operated actuation system in a clutch bell housing, in which a supply line, in particular a substantially dimensionally stable angle adapter, is connected to an actuation cylinder of the actuation system for supplying a pressure medium into the actuation cylinder of the actuation system, and a retaining sleeve is provided which is rotatably connected to the supply line via a locking device for rotatable fastening in a supply opening of a clutch bell housing, wherein the locking device blocks a lateral movement of the supply line relative to the retaining sleeve in a closed angular position of the retaining sleeve to the supply line and allows the lateral movement of the supply line relative to the retaining sleeve in an open angular position of the retaining sleeve to the supply line, the retaining sleeve is aligned substantially coaxially with the supply opening of the clutch bell housing,wherein the actuating cylinder is positioned pivoted relative to a designated end position about a pivot axis running along a center line of the retaining sleeve, the retaining sleeve is subsequently inserted into the supply opening and rotatably connected to the clutch bell, the actuating cylinder being pivoted into the designated end position, and a connecting adapter is subsequently inserted into the supply line via the supply opening through the clutch bell, the connecting adapter blocking rotation of the retaining sleeve from the closed angle position to the open angle position via a blocking means, in particular to form a pressure line, which can be designed and further developed as described above.

[0019] The method can be designed and developed in particular as described above with reference to the pressure line and / or the actuation system. As a result, the actuation cylinder can be easily moved past protruding components of the clutch bell housing during the insertion movement of the retaining sleeve into the supply opening and can only be positioned in the intended end position by the subsequent pivoting movement, in which end position the actuation cylinder can be connected to the clutch bell housing, for example by screwing it to the clutch bell housing. The actuation system can be easily installed by a pivoting movement in the closed angle position of the retaining sleeve and, after slightly loosening the connection adapter, can be easily removed by a lateral movement in the open angle position, thus enabling a pressure-operated actuation system for actuating a clutch of a motor vehicle with minimal assembly and / or disassembly effort.

[0020] In particular, a detachable plug inserted into the supply line is provided for holding the retaining sleeve in the closed-angle position, in particular by frictional engagement, in particular for forming the pressure line with a plug described above. The plug is exchanged after the retaining sleeve has been rotatably connected to the clutch bell housing by the connection adapter. The plug can prevent the ingress of dirt into the actuation system, in particular into an actuation cylinder of the actuation system, during assembly. Furthermore, the retaining sleeve can be held in the closed-angle position by the plug during assembly, thus preventing the retaining sleeve from being inadvertently separated from the supply line during assembly of the actuation system in the clutch bell housing.The plug can, in particular, have a radial extension such that, when inserted, the plug can be guided outward through the supply opening of the clutch bell during assembly, allowing the plug to be removed from outside the clutch bell. After the retaining sleeve has been secured in the supply opening of the clutch bell, the plug can be removed and replaced with the connection adapter.

[0021] The invention further relates to a method for disassembling a pressure-operated actuation system from a clutch bell housing, in which a supply line, in particular a substantially dimensionally stable angle adapter, is provided for supplying a pressure medium into an actuation cylinder of the actuation system, and a retaining sleeve is rotatably connected to the supply line via a locking device, wherein the locking device blocks a lateral movement of the supply line relative to the retaining sleeve in a closed angular position of the retaining sleeve to the supply line and allows the lateral movement of the supply line relative to the retaining sleeve in an open angular position of the retaining sleeve to the supply line,wherein the retaining sleeve is rotatably mounted in a supply opening of a clutch bell housing, and a connection adapter projecting through the retaining sleeve into the supply line is provided for penetrating the clutch bell housing via the supply opening, wherein the connection adapter has a locking means for locking a rotation of the retaining sleeve from the closed angle position to the open angle position, the connection adapter is moved out of the supply line at least far enough that a locking effect of the locking means is canceled, subsequently the retaining sleeve is rotated into the open angle position, and subsequently the supply line is moved together with the actuating cylinder away from the clutch bell housing in a disassembly direction laterally to the retaining sleeve.

[0022] The method can be designed and developed in particular as described above with reference to the pressure line and / or the actuation system. During disassembly, in particular, a transmission input shaft can protrude into the actuation cylinder of the actuation system, wherein the lateral movement of the pressure line can prevent the actuation cylinder from striking the transmission input shaft. The actuation system can be easily installed by a pivoting movement in the closed angle position of the retaining sleeve and, after slightly loosening the connection adapter in the open angle position, can be easily disassembled by a lateral movement, thus enabling a pressure-operated actuation system for actuating a clutch of a motor vehicle with minimal assembly and / or disassembly effort.

[0023] The invention further relates to a method for assembling and disassembling a pressure-operated actuation system, in which the above-described method for assembling a pressure-operated actuation system in a clutch bell housing is first carried out, followed by the above-described method for disassembling the pressure-operated actuation system from the clutch bell housing. The actuation system can be easily assembled by a pivoting movement in the closed-angle position of the retaining sleeve and, after slightly loosening the connection adapter in the open-angle position, can be easily disassembled by a lateral movement, thus enabling a pressure-operated actuation system for actuating a clutch of a motor vehicle with minimal assembly and / or disassembly effort.

[0024] The invention will be explained below by way of example with reference to the accompanying drawings using preferred embodiments, wherein the features presented below can represent an aspect of the invention both individually and in combination. They show: Fig. 1: a schematic perspective view of an actuation system before assembly, Fig. 2: a schematic perspective view of the actuation system of Fig. 1 during assembly, Fig. 3: a schematic perspective sectional view of a control system based on the Fig. 1 based actuation system after assembly, Fig. 4: a schematic perspective sectioned detail view of a pressure line of the actuation system from Fig. 3 and Fig. 5: a schematic perspective view of the actuation system of Fig. 3 during disassembly.

[0025] The Fig. The actuating system 10 shown in Figure 1 comprises an annular actuating cylinder 12 that is rigidly connected to a pressure line 14. The pressure line 14 has a supply line 16 that is directly connected to the actuating cylinder 12 and is designed, in particular, as an angle adapter made of a dimensionally stable plastic. A retaining sleeve 18 is connected to the supply line 16 via a locking device 20 so that it can rotate about a center line 22 of the supply line 16 and the retaining sleeve 18. In a closed angular position of the retaining sleeve 18 relative to the supply line 16, the locking device 20 can block any axial movement of the retaining sleeve 18 relative to the supply line 16, thus preventing unintentional separation.The retaining sleeve 18 has locking hooks 24 extending away from the supply line 16 in order to rotatably clip the retaining sleeve 18 into a supply opening 26 of a clutch bell 28 of a friction clutch for coupling a drive shaft of a motor vehicle engine to a transmission input shaft 30 of a motor vehicle transmission. In a state prior to assembly of the actuation system 10 with the clutch bell 28, the pressure line 14 has a plug 32 projecting into the supply line 16. The plug 32 can be substantially hollow and have a closed end face 34 at its end projecting into the supply line 16 in order to close the supply line 16. The plug 32 is preferably made of a thermoplastic material.The plug 32 can in particular have at least one web 36 projecting radially outwards, preferably running circumferentially, by means of which the holding sleeve 18 can be held frictionally in a defined angular position relative to the supply line 16.

[0026] As in Fig. 2, the actuation system 10 can be compared to the one shown in Fig. 3 shown end position in a position pivoted about the center line 22 of the supply line 16 and the supply opening 26 of the clutch bell 28, in which the holding sleeve 18 can be inserted into the supply opening 26 by a linear movement 38. Subsequently, the actuating cylinder 12 of the actuating system 10 can be pivoted past protruding components into a mounting recess 40 of the clutch bell 28. Subsequently, as in Fig. As shown in Figure 3, the actuating cylinder 12 is firmly connected to the clutch bell housing 28 via fastening means 40 designed as a screw connection. When the clutch is assembled, the transmission input shaft 30 extends through the clutch bell housing 28 and the actuating cylinder 12 into the interior of the clutch. Additionally, the plug 32 is replaced by a connection adapter 42, via which the actuating cylinder 12 can be connected to a pressure source provided outside the clutch.

[0027] As particularly in Fig. As shown in Figure 4, the connection adapter 42 can have a radially outwardly projecting, shoulder-like locking means 44, which extends between two circumferentially following latching hooks 24 and has at least one circumferentially directed locking stop 46 to block rotation of the retaining sleeve 18 from the closed angular position to the open angular position. Optionally, the locking means 44 can engage in a recess 48 provided in the region of the supply opening 26 to block relative rotation of the locking means 44 to the clutch bell 28 and / or to position the connection adapter 42 in a defined angular position relative to the clutch bell 28. Additionally or alternatively, the connection adapter 42 can have a protruding position fixing element in the form of a position fixing lug 50, which can strike the coupling bell 28 in the assembled state of the connection adapter 42 in order to block rotation of the holding sleeve 18 from the closed angle position into the open angle position.To form the locking device 20, the holding sleeve 18 has at least one locking projection 52 projecting in the axial direction, which radially covers the supply line within an angular range of ≤ 180°. A locking lug 54 projects radially inward from the locking projection 52, with the aid of which a collar 56 projecting radially outward from the supply line 16 can be gripped in the closed angular position in order to block any axial relative movement of the holding sleeve 18 to the supply line 16. The supply line 16 can in particular have a locking groove 58, in which a locking means 60, in particular a snap ring designed as a retaining ring, of the connection adapter 42 and / or the plug 32 can releasably engage.

[0028] As in Fig.As shown in Figure 5, for disassembly of the actuation system 10 with the transmission input shaft 30 projecting into the clutch bell housing 28, the connection adapter 42 can first be loosened. The retaining sleeve 18 can then be rotated from the closed-angle position to the open-angle position, in which the supply line 16 is no longer held captively between the locking projection 52 of the locking device 20 and the clutch bell housing 28. Instead, the supply line 16 can be moved out of the retaining sleeve 18 together with the actuation cylinder 12 by a lateral movement 62, without the actuation cylinder 12 connected to the supply line 16 striking the transmission input shaft 30.
