Description
Technical Field
The present invention relates to a bellows for a motor vehicle clutch or motor vehicle brake actuating system, and to a motor vehicle clutch or motor vehicle brake actuating system, in particular to a center release.
Background
Differently shaped bellows and systems (e.g. a central separator) are known from the prior art to avoid or significantly reduce dust ingress.
The known bellows are characterized by a symmetrical arrangement or uniform wall thickness of the corrugations of the two identically configured ends and of the corrugated section between the two ends.
In order to achieve flawless handling of the bellows, a stable fixing and limiting (axial displacement) on both ends of the bellows is necessary.
In actuating systems for motor vehicle clutches or motor vehicle brakes, in particular in pneumatic center separators, difficulties in integrating the bellows in the known embodiments occur due to the compact design of the actuating system and the extremely narrow installation space in the region of the guide tube.
Since the conventional bellows release its fastening to the handling system in a simple manner, dust can reach the handling system and thus interfere with the functioning of the handling system.
Disclosure of Invention
The object of the present invention is therefore to specify a bellows for an actuating system of a motor vehicle clutch or motor vehicle brake, and to specify an actuating system of a motor vehicle clutch or motor vehicle brake, which ensures a reliable arrangement of the bellows on the guide tube and/or on a piston element of the actuating system, and thus an improved sealing against dirt.
According to the invention, this object is achieved by the features of the independent claims. Further advantageous embodiments are the subject matter of the dependent claims.
According to the invention, a first aspect of the invention comprises a bellows for an actuating system of a motor vehicle clutch or motor vehicle brake and for sealingly connecting a guide tube of the actuating system and a piston element movable along the guide tube, the bellows comprising the following features:
a first connection section for connection to a guide tube of a steering system, and
a second connecting section for connection with a piston element of the actuating system.
Advantageously, the second connecting section comprises a fixing region for arrangement on the piston element and a blocking region for prohibiting axial movement when the bellows is compressed.
It is also preferred that the stop region has at least the length of the fixing region in the axial direction.
The axial length is understood here to mean the section which extends along the bellows, which is preferably configured in the form of a hollow cylinder.
In other words, the axial direction preferably extends between the first connection section and the second connection section.
Preferably, the stop region has in the axial direction 100 to 200 percent, preferably 120 to 200 percent, of the length of the fixing region in the axial direction. That is, in this way the stop region lengthens the second connecting section in the axial direction of the bellows.
It is also advantageous if the fastening region and the blocking region are integrally formed. This eases manufacturing and reduces production costs.
It is furthermore advantageous if the fastening region comprises a latching element for latching onto a complementarily configured latching element, in particular a latching element of a piston element of the actuating system. In this way, the bellows can be connected to, for example, the central separator via the fastening region or via the latching element. Furthermore, the locking element prevents a relative movement of the bellows relative to the piston element of the actuating system in the axial direction.
Additionally or alternatively (and/or) it is advantageous if the blocking region extends the bellows in the axial direction and extends away from the bellows. In this way, a movement space in the axial direction can be filled up to the structural element, in particular to the holding element of the actuating system.
It is also advantageous if the first connection section comprises a fixed receiver for arrangement on a guide tube of the handling system, in order to inhibit a relative axial movement of the bellows relative to the guide tube.
In addition or alternatively (and/or alternatively) it is advantageous if a fastening element, which is formed complementarily to the fastening receptacle and is preferably arranged on the guide tube of the actuating system, engages in a form-fitting manner into the fastening receptacle. This prevents the first connection section from moving axially relative to the guide tube of the actuating system.
It is furthermore advantageous if the corrugated section with corrugations extends in the axial direction of the corrugated tube between the two connection sections.
The bellows preferably has an elastomer as material.
The bellows advantageously extends in the axial direction.
A second aspect of the invention comprises an actuation system of a motor vehicle clutch or motor vehicle brake, in particular comprising a center decoupler.
It should be explicitly noted that: the features of the bellows (as they are mentioned under the first aspect) can be used alone or in combination with one another in an actuating system of a motor vehicle clutch or motor vehicle brake.
In other words, the features mentioned above in relation to the bellows in the first aspect of the invention can also be combined with further features in the second aspect of the invention here.
Advantageously, the actuation system (in particular the center decoupler) of the motor vehicle clutch or motor vehicle brake comprises a bellows, which preferably has the features explained under the first aspect of the present description.
The bellows advantageously comprises a first connection section and a second connection section.
The second connecting section preferably has a stop region and a fastening region for arrangement on the piston element.
The restricted area preferably inhibits axial movement when the bellows is compressed.
It is furthermore advantageous if the handling system comprises a guide tube.
The bellows preferably at least partially encloses the guide tube.
It is furthermore advantageous if the actuating system has a piston element which is arranged so as to be axially movable along the guide tube.
At the end of the guide tube, a fastening element, in particular a fastening ring, for fastening the bellows is advantageously arranged. In this way the bellows is given the following possibilities: which is connected to the guide tube and maintains its position relative to the guide tube.
It is also advantageous if the actuating system comprises a retaining element, which is preferably designed as a disk spring, for the axially immovably connection of the piston element to the bearing, in particular the release bearing.
Can also be provided with: the holding element is configured as a disk spring which tightens the bearing, in particular the release bearing, in the axial direction in order to ensure the position of the bearing relative to the piston element.
Preferably, the blocking region is supported on the holding element in the axial direction in the compressed state of the bellows, in particular of the bellows section. In this way, the release of the fastening region from the piston element can be prevented, since the blocking region prevents the second connecting section from moving in the axial direction toward the holding element due to its extension or its design or its volume. In other words, the blocking region of the second connecting section is moved toward the holding element during compression of the bellows, wherein the second connecting section is prevented from being released from the piston element due to the spatial configuration of the blocking region.
It is furthermore advantageous if the blocking region engages in the axial direction on the fastening region in order to extend the bellows in the axial direction to the retaining element, and the blocking region extends away from the bellows in the axial direction. In the case of a compressed bellows, the axial extension achieves that the second connecting section retains its axial position on the piston element by means of its fastening region and its locking region.
The piston element preferably has a snap-in element. The arrangement of the bellows on the piston element is achieved by means of the snap-in element.
The stop region of the bellows advantageously extends from the snap-in element of the piston element to the holding element in order to limit the movement space of the second connecting section (in particular in the case of a compression of the bellows). In this way, the release of the bellows from the piston element can be avoided and the position of the bellows relative to the piston element can be ensured.
It is also preferred that the fastening region has a latching element. The locking element enables the bellows to be inserted into the locking element of the piston element, so that a connection between the bellows and the piston element is achieved.
Advantageously, the latching element and the snap-in element are geometrically complementarily configured such that in the snapped-in state they form a form-fit connection in order to connect the bellows axially immovably with the piston element.
It is furthermore advantageous if the blocking region has an axial length in the axial direction, which extends from the fastening region to the holding element of the actuating system, so that axial displacement of the second connecting section (in particular in the case of a bellows compression) in the direction of the holding element can be prevented.
In addition or alternatively (and/or alternatively) it is possible for the first connection section to comprise a fastening receptacle which preferably encloses the complementarily configured fastening element in a form-fitting manner. Whereby axial movement between the first connection section and the guide tube can be inhibited.
Next, the inventive concept shown above is expressed in supplementary terms.
This concept preferably (shown simplified) relates to a bellows for an actuating system of a motor vehicle clutch or motor vehicle brake, and to an actuating system with a bellows.
In this case, it is advantageous if the bellows has the correct corrugation in each operating point (in the installed state and in the forward and rear piston positions or in the maximum and minimum compression) and is reliably fixed on, for example, the guide tube and/or the piston element of the actuating system.
Because in the bellows from the prior art the bellows or its ends are released from the piston element of the handling system (such as for example a pneumatic center separator), whereby the handling system loses its dirt protection function.
Furthermore, the bellows end can move, for example, in the direction of the inner ring of the rotation of the release bearing, as a result of which the bellows is destroyed and likewise loses its dirt protection function.
The bellows can also get stuck on the piston, on the release bearing or even on the clutch which can be operated by the central separator/operating system and impair its function.
In this context, the following tasks are particularly preferably provided: in particular, a bellows is developed according to the installation space of the center separator, which preferably achieves a defined piston stroke (for example 38 mm) and advantageously a reliable fastening of the two bellows ends.
In addition, it is advantageous if the bellows is designed such that the disk spring for fastening the release bearing can be assembled in advance, and that there is sufficient installation space for assembly.
In other words, it is advantageous if the bellows performs the usual bellows function at a narrow position in the region of the guide tube of the actuating system.
The axial fixing of the bellows and the embodiment of the bellows at the end of the bellows are preferably referred to here.
The bellows is advantageously not symmetrically configured at the end, but is advantageously solid. This solid embodiment is advantageous in that the bellows does not come loose from the groove/snap-in element of the piston element of the actuating system when the bellows is actuated into the forward piston position (maximum compression of the bellows).
Advantageously, the solid embodiment of the bellows end prevents the bellows from loosening or bouncing off the groove on the piston element of the actuating system by axial limiting. The bellows thus preferably remains fixed on the movable piston element and ensures the function of the bellows.
Drawings
The invention is explained in detail below with reference to the examples in conjunction with the attached drawing. Here, schematically shown is:
fig. 1 shows a cross-sectional view of a bellows according to the present invention;
fig. 2 shows a cross-sectional view of a handling system according to the invention with the bellows of fig. 1 in a first state;
FIG. 3 shows an enlarged view of FIG. 2 with the bellows of FIG. 1 in a first state; and
fig. 4 shows the bellows of fig. 3 in a second state.
In the following description, the same reference numerals are used for the same objects.
Detailed Description
Fig. 1 shows a cross-sectional view of a bellows 1 according to the invention. More precisely, fig. 1 shows a bellows 1 for installation in an actuating system 20 of a motor vehicle clutch or motor vehicle brake and for the sealed connection of a guide tube 21 of the actuating system 20 and a piston element 22 which can be moved along the guide tube 21.
Fig. 1 shows that the bellows 1 has a first connecting section 2 for connection to a guide tube 21 of the actuating system 20 and a second connecting section 3 for connection to a piston element 22 of the actuating system 20.
The second connecting section 3 has a fastening region 5 for arrangement on the piston element 22 and a blocking region 6 for prohibiting axial movement when the bellows 1 is compressed.
The blocking region 6 has 120 percent of the length of the fastening region 5 in the axial direction a and is formed integrally with the fastening region 5. Further, the bellows 1 has an elastomer as a material.
The stop region 6 thus extends the bellows 1 in the axial direction a and thus extends away from the bellows 1 in the axial direction a. This has the following advantages: by means of this configuration, a movement space in the axial direction a to a structural element (for example, the holding element 24 of the actuating system 20) can be filled.
The fastening region 5 has a latching element 7 for latching onto a complementarily configured latching element 23 of the piston element 21 of the actuating system 20.
Furthermore, the first connection section 2 has a fixing receptacle 4 for arrangement on the guide tube 21 of the handling system 20 in order to inhibit a relative axial movement of the bellows 1 relative to the guide tube 21.
In this case, a fastening element 25, which is configured complementarily to the fastening receptacle 4 and can be arranged on the guide tube 21 of the actuating system 20, engages in a form-locking manner into the fastening receptacle 4 in order to prevent an axial displacement of the first connecting section 2.
Fig. 1 also shows that a corrugated section 8 with corrugations extends between the two connection sections 2, 3 in the axial direction a of the corrugated tube 1.
Fig. 2 to 4 are processed together in the following description, wherein fig. 2 shows an actuating system 20 of a motor vehicle clutch or motor vehicle brake, which has a bellows 1 in a first state.
While figure 3 shows an enlarged view of figure 2 with the bellows of figure 1 in a first state and figure 4 shows the bellows of figure 3 in a second state.
Returning to fig. 1, an actuating system 20 or a center release of a motor vehicle clutch is shown.
The handling system 20 has a bellows 1, as already explained in the description of fig. 1.
Furthermore, as shown in fig. 2, the handling system 20 comprises a guide tube 21 at least partially surrounded by the bellows 1 and a piston element 22 arranged axially movably along the guide tube 21.
At the end of the guide tube 21, a fastening element 25 or a fastening ring 25 for fastening the bellows 1 is arranged.
Furthermore, actuating system 20 has a holding element 24, which in the present case is designed as a disk spring (better visible in fig. 3 and 4). The retaining element 24 serves to connect the piston element 22 to the release bearing 26 in an axially immovable manner.
The manipulation system 20 of fig. 2 is explained in detail with reference to fig. 3 and 4.
According to fig. 3 and 4, the bellows 1 of the handling system 20 thus comprises a first connection section 2 and a second connection section 3.
The second connecting section 3 has a stop region 6 and a fastening region 5 for arrangement on the piston element 22.
The restricted area 6 prohibits axial movement when the bellows 1 is compressed (see fig. 4).
The stopper region 6 achieves this by: the blocking region has an axial length in the axial direction a, which extends from the fastening region 5 or from the snap-in element 23 of the piston element 22 to the holding element 24 of the actuating system 20. Thus, an axial displacement of the second connecting section 3 in the direction of the holding element 24 or the disk spring 24 is prevented.
Furthermore, the blocking region 6 engages in the axial direction a on the fastening region 5 in order to extend the bellows 1 in the axial direction a to the retaining element 24, and extends away from the bellows 1 in the axial direction a.
The fastening region 5 has a latching element 7, while the piston element 22 has a snap-in element 23, wherein the latching element 7 and the snap-in element 23 are geometrically configured complementarily. The two are thus form-locking in the engaged state, so that the bellows 1 is connected to the piston element 22 in an axially immovable manner.
In contrast, the first connecting section 2 has a fastening receptacle 4 which surrounds the complementarily configured fastening element 25 in a form-locking manner in order to prevent an axial displacement between the first connecting section 2 and the guide tube 21.
Fig. 1, 2 and 3 show the bellows 1 in a first state, with the greatest extent of the bellows 1, whereas in fig. 4 the bellows 1 is compressed to the greatest extent.
In this state, the blocking region 6 is supported on the holding element 24 in the axial direction a, in order to inhibit the release of the fastening region 5 from the piston element 22.
