Description

[0001] The invention relates to a device for compensating for tolerances between two components to be joined together.

[0002] Such a tolerance compensation device is generally known and is used, for example, in vehicle manufacturing, particularly when it comes to bolting two components together across a gap with tolerances. For this purpose, the tolerance compensation device is positioned between the components to be joined, and a screw element for fastening the components, such as a screw or a threaded bolt, is guided through appropriately provided openings in the components and through the tolerance compensation device.When the screw element is tightened, the compensating element is rotated relative to the base element by means of a drive spring connected between the screw element and the compensating element, and is thereby moved axially from its initial position to the base element, for example, extended out of the base element, until it reaches its compensating position, in which the base element and the compensating element each rest against one of the components and thus bridge the joining gap.

[0003] For example, DE 298 10 172 U1 discloses a device for connecting components, comprising a connecting screw and two spacer rings surrounding the connecting screw that can be rotated relative to each other and which support each other in the axial direction via helical stiffening surfaces.

[0004] The object of the present invention is to provide a device for compensating for tolerances between at least two components to be joined together, which is improved compared to the prior art.

[0005] The problem is solved by the features specified in claim 1.

[0006] Advantageous embodiments of the invention are the subject of the dependent claims.

[0007] The problem is solved by a device according to the invention for compensating for tolerances between at least two components to be connected to one another by means of a screw element, wherein the device comprises at least one base element, a first compensating element connected to the base element, in particular in engagement, for example in thread engagement, and a second compensating element connected to the first compensating element or to the base element, in particular in engagement, for example in thread engagement, and wherein the first compensating element and the second compensating element can each be moved from a starting position to a compensating position by rotation relative to the base element and relative to each other. In particular, the compensating elements and the base element are designed to be telescopically movable relative to each other and / or within each other.

[0008] The advantages achieved with the invention consist in particular of the fact that, by means of such a nested and / or telescopic arrangement of the base element and the compensating elements, the device can be designed to be comparatively small and compact, while still being able to compensate for comparatively large tolerances between at least two components. Furthermore, no compensation path, in particular the tolerance compensation path, of the device needs to be shortened to achieve a comparatively smaller and more compact design.

[0009] The device is, for example, a tolerance compensation device, particularly for compensating for tolerances when attaching a component to a part with a bore or blind hole. Tolerance compensation devices are part of fasteners used to fasten components and parts to each other, for example in motor vehicles. Such tolerance compensation devices are, for instance, pressed into one of the parts. In particular, the device is an automatic tolerance compensation system.

[0010] In one possible embodiment, the first compensating element is arranged on a first end face of the base element. The first compensating element can be adjusted relative to the base element to compensate for tolerances between two components. The first compensating element is axially movable relative to the base element. The first compensating element is movably arranged in a cavity of the base element.

[0011] The first compensating element can be designed as a hollow cylindrical compensating element that engages or can be brought into thread engagement with a base element, and which can be axially moved from the initial position to a compensating position by rotating it relative to the base element.

[0012] In one possible embodiment, the second compensating element is arranged together with the first compensating element on the first end face of the base element. The second compensating element can be adjusted relative to the first compensating element and the base element to compensate for tolerances between two components. The second compensating element is axially movable relative to the first compensating element and the base element.

[0013] The expansion directions of the compensating elements are the same. Both expansion directions correspond, for example, to an upward or downward movement out of the base element. The first compensating element and the second compensating element can be extended upward or downward from the base element, for example, by screwing or rotating them out.

[0014] The second compensating element is movably arranged within a cavity of the first compensating element. The first compensating element can be designed as an intermediate element, in particular an intermediate compensating element. The first compensating element can be arranged between the second compensating element and the base element. The compensating elements and the base element are designed to be telescopically displaceable or movable relative to each other. The second compensating element can be designed as a hollow cylindrical compensating element that engages with the first compensating element in a threaded manner or can be brought into such engagement. This second compensating element can be axially moved from its initial position to a compensating position by rotating it relative to the first compensating element and thus to the base element. The second compensating element can, in particular, be a main compensating element.

[0015] When the screw element is tightened, the second compensating element can initially be moved relative to the first compensating element, in particular unscrewed. Subsequently, by further tightening the screw element, the first compensating element can be moved relative to the base element, in particular unscrewed from the base element.

[0016] The first compensating element can be used as an additional intermediate element between the base element and the second compensating element to compensate for larger tolerances without having to change the overall height, technical and mechanical properties of the device.

[0017] In summary, as described above, the invention relates to a first embodiment, according to which a device for compensating for tolerances between two components to be joined together by means of a screw element comprises at least - a basic element, - a first compensating element that is connected to, in particular engaged with, the basic element or can be brought into contact with it and - a second compensating element that is connected to, in particular engaged with, the first compensating element or can be brought into contact with it, - wherein the first compensating element is movable from the basic element by twisting it relative to the basic element, in particular movable out or rotatable, and - wherein the second compensating element can be moved out of the first compensating element by rotating it relative to the first compensating element, in particular being movable out or rotatable.

[0018] In an alternative embodiment, the second compensating element is arranged on a second end face of the base element opposite the first end face. The second compensating element can thus be arranged on an end face of the base element opposite the first compensating element.

[0019] This embodiment relates to a second embodiment, according to which a device for compensating for tolerances between three components to be connected to each other by means of a screw element comprises at least - a basic element, - a first compensating element that is connected to, in particular engaged with, the basic element or can be brought into contact with it and - comprises a second compensating element that is connected to, in particular interlocking with, the basic element or that can be brought into contact with it, - wherein the compensating elements are assigned to two opposing end faces of the basic element, - wherein the first compensating element is movable from the basic element by twisting it relative to the basic element, in particular movable out or rotatable, and - the second compensating element can also be moved out of the basic element by twisting it relative to the basic element, in particular being movable out or twistable out.

[0020] The extension directions of the compensating elements are opposite. For example, the first extension direction of the first compensating element corresponds to an upward movement out of the base element. A second extension direction of the second compensating element corresponds to a downward movement out of the base element. The first compensating element can be extended upwards out of the base element, for example, by screwing or screwing it out. The second compensating element can be extended downwards out of the base element, for example, by screwing or screwing it out.

[0021] The second compensating element can be adjusted relative to the base element to compensate for tolerances between two components. The second compensating element is axially movable relative to both the base element and the first compensating element. This allows tolerances between a total of three components to be compensated: one tolerance above the base element can be compensated by axially adjusting the first compensating element, and another below the base element can be compensated by axially adjusting the second compensating element. The base element and the compensating elements are arranged in a nested configuration. The compensating elements and the base element are designed to be telescopically slid or moved within each other.The second compensating element can be designed as a hollow cylindrical compensating element that engages or can be brought into thread engagement with a base element, and which can be axially moved from the starting position to a compensating position by rotating it relative to the base element.

[0022] The base element and the second compensating element can each be designed as a double ring. Each double ring can consist of an inner ring, an outer ring, and a connecting section. The first compensating element can be designed as a single ring.

[0023] The double rings can be nested such that the outer ring of the second compensating element is positioned between the inner ring and the outer ring of the base element. Simultaneously, the inner ring of the base element can be positioned between the inner ring and the outer ring of the second compensating element. The inner ring of the second compensating element and a main threaded body of the first compensating element can be located within the cavity of the base element. This allows for a nested arrangement that does not affect the overall height of the device.

[0024] Furthermore, the device can also be designed to be relatively compact with three components.

[0025] When the screw element is inserted, one of the compensating elements, which is the first to engage with the screw element, can initially be moved axially from its initial position to a compensating position relative to the base element, in particular by rotating it out. Subsequently, by further screwing in the screw element, the other compensating element can be moved from its initial position to a compensating position relative to the base element, in particular by rotating it out.

[0027] Corresponding parts are marked with the same reference symbols in all figures.

[0028] Fig. Figure 1 shows schematically in perspective view a first embodiment of a device 10 according to the invention for compensating tolerances between two components 12, 14 to be joined together, which are indicated by dashed lines.

[0029] The device 10 can, for example, be a tolerance compensation device and / or a tolerance compensation device.

[0030] A screw element 16 for connecting the components 12, 14 can be passed through the device 10 (also indicated by a dashed line).

[0031] The device 10 comprises a base element 20. The device 10 comprises a first compensating element 30, which is movable by rotation relative to the base element 20. The first compensating element 30 is arranged coaxially with the base element 20. The device 10 comprises a second compensating element 40, which is movable by rotation of the first compensating element 30 relative to the first and to the base element 20. The second compensating element 40 is arranged coaxially with the base element 20. In particular, the base element 20 and the compensating elements 30 and 40 are arranged coaxially with each other and axially movable relative to each other.

[0032] In the illustrated embodiment, the first compensating element 30 is designed as an intermediate element 30a, in particular an intermediate compensating element. The first compensating element 30 is arranged between the second compensating element 40 and the base element 20. The compensating elements 30 and 40 are each telescopically movable relative to each other and relative to the base element 20, in particular, they are slidably movable.

[0033] The base element 20 comprises a cavity 22 in which the first compensating element 30 is received in a starting position P1. The first compensating element 30 comprises a cavity 32 in which the second compensating element 40 is received in the starting position P1. The second compensating element 40 is configured to engage with the screw element 16, in particular by friction engagement. The second compensating element 40 comprises a cavity 42 in which at least one drive element 50, as shown in Fig. Figure 3 shows how the drive element 50 is arranged to form a connection with the screw element 16 during insertion. The drive element 50, for example, rests against a cylindrical surface of the inner cavity 42 of the second compensating element 40. The drive element 50 can be a drive spring or another spring element.

[0034] The first compensating element 30 can be designed as a hollow cylindrical compensating element 30 which is in thread engagement with or can be brought into engagement with a base element 20 and which can be axially moved from the initial position P1 to a compensating position P2 by rotating it relative to the base element 20.

[0035] The second compensating element 40 can be designed as a hollow cylindrical compensating element 40 which is in thread engagement with or can be brought into thread engagement with the first compensating element 30, and which can be axially moved from the initial position P1 to a compensating position P2 by rotating it relative to the first compensating element 30 and thus to the base element 20.

[0036] The compensating elements 30, 40 and the base element 20 are axially, in particular telescopically, movable relative to each other and / or within each other, in particular movable. This allows different, for example comparatively larger, tolerances and longer compensating paths between two components 12, 14 to be compensated for, while maintaining a desired compact overall height of the device 10.

[0037] The base element 20 can be pre-fixed to one of the components 12, 14. The device 10 can be pre-fixed to the first component 12 by means of the base element 20.

[0038] Fig. Figure 2 schematically shows in sectional view the device 10 in the starting position P1 and Fig. Figure 3 schematically shows in sectional view the device 10 in the compensation position P2.

[0039] For connecting, in particular screwing, the components 12, 14, the device 10 is arranged between them and the screw element 16 or another fastening element is inserted from above through an opening 142 of the second component 14, the device 10 and optionally additionally, for example, through an opening 122 (in Fig. 11 shown) of the first component 12 through.

[0040] The screw element 16 can engage, for example by friction, with the drive element 50, which is arranged in the second compensating element 40, in order to transmit a torque exerted by the screw element 16 to the second compensating element 40 and subsequently, by adjustment, in particular rotation, of the second compensating element 40 to the first compensating element 30. By adjustment, in particular rotation, of the second compensating element 40, it is moved out of the first compensating element 30, which is designed as an intermediate element 30a, in particular extended. The torque generated in this process is transmitted to the first compensating element 30, which is designed as an intermediate element 30a, whereby the first compensating element 30 is moved relative to the base element 20, in particular extended.

[0041] The base element 20 can include an internal thread 24. The first compensating element 30 can include an external thread 34 corresponding to the internal thread 24 of the base element 20 and an internal thread 36. The second compensating element 40 can include an external thread 44 corresponding to the internal thread 36 of the first compensating element 30.

[0042] When the screw element 16 is tightened, the second compensating element 40 is rotated relative to the first compensating element 30 via the drive element 50 connected between the screw element 16 and the second compensating element 40, and thereby from its initial position P1, as shown in Fig. The second compensating element 40 is moved axially relative to the base element 20, for example, extended from the base element 20, until it reaches its compensating position P2. Further rotation of the screw element 16 and the second compensating element 40 transmits the torque to the first compensating element 30, which is designed as an intermediate element 30a. This rotates the first compensating element 30 relative to the base element 20 and moves it from its initial position P1 to its compensating position P2, until the second compensating element 40, in particular an end-face contact section 46 of the second compensating element 40, abuts one of the components 12, 14. Thus, for example, a joining gap can be compensated for or bridged.

[0043] As in Fig. As shown in Figure 3, the turning directions D1 and D2 of the compensating elements 30 and 40 are the same. Turning direction D1 and D2 refer to a screwing direction, in particular an unscrewing direction. When the screwing element 16 is screwed into the second compensating element 40, the second compensating element 40 can be moved out of the first compensating element 30 in turning direction D2, in particular unscrewing it. Simultaneously or subsequently, the first compensating element 30 can be moved out of the base element 20 in turning direction D1, which corresponds to turning direction D2 of the second compensating element 40, in particular unscrewing it.

[0044] For example, section 46 of the system is a flange section and / or a stop ring.

[0045] The device 10 includes at least one anti-rotation device 60, as shown in Fig. Figure 3 shows the anti-rotation device 60. It can comprise a number of anti-rotation elements 62, 64, 66, 68. A first anti-rotation element 62 can be arranged at an end face of the base element 20. The first anti-rotation element 62 can be directed into the cavity 22 of the base element 20. A corresponding second anti-rotation element 64 can be arranged on the outside of the first compensating element 30, wherein, in the compensating position P2, the anti-rotation elements 62, 64 engage or abut each other and prevent the first compensating element 30 from rotating out of the base element 20.

[0046] A third anti-rotation element 66 can be arranged on the inside of the first compensating element 30. A corresponding fourth anti-rotation element 68 can be arranged at an end face of the second compensating element 40. The fourth anti-rotation element 68 can be arranged on the outside of the second compensating element 40 and directed into the cavity 32 of the first compensating element 30, wherein in the compensating position P2 the anti-rotation elements 64, 68 engage or abut each other and prevent the second compensating element 40 from rotating out of the first compensating element 30.

[0047] The anti-rotation elements 62, 64, 66, 68 can form corresponding detent elements and counter-detent elements. For example, one of the anti-rotation elements 62, 64, 66, 68 can be designed as a pressed-in ring, an embossed thread, or a thread relief. The other anti-rotation element 62, 64, 66, 68 can be designed as a corresponding counter-element, for example, as a stop, a groove, a relief, or an embossing.

[0048] The base element 20 comprises a holding device 70. The base element 20 and the holding device 70 can be formed as a single piece. The holding device 70 can be designed as a retaining ring or retaining clip. The holding device 70 serves as a connecting element to a customer interface or to one of the components 12, 14. Alternatively, the holding device 70 is designed as a separate element and connected to the base element 20. The base element 20 can be held in position by means of a positive-locking connection and / or a friction-locking connection in a recess 72 of the holding device 70. The base element 20 is secured against axial movement in the holding device 70 and is thus fixedly arranged. For fixing the device 10, for example on and / or in the first component 12, in particular in an opening 122 of the first component 12, the holding device 70 comprises retaining arms 74.The retaining arms 74 can each be designed in the form of a clip, for example L-shaped or J-shaped clips, or as a hinge or bayonet device.

[0049] The device 10 can also, for example, be a safety arrangement 80, as shown in Fig. The locking arrangement 80, as shown in Figure 1, comprises a locking element 82 formed on an outer circumference, for example, on an edge of the contact section 46 of the second locking element 40. The first locking element 82 is integrally formed on the second locking element 40. The first locking element 82 is designed as a projecting pin, cam, or lug. Furthermore, the locking arrangement 80 comprises a second locking element 84 arranged on the base element 20 and / or on the holding device 70. The second locking element 84 can be integrally formed on the base element 20 and / or on the holding device 70. The second locking element 84 is, for example, a counterpart element corresponding to the first locking element 82. The second locking element 84 can be designed as a stop, pin, cam, or lug.For example, the second locking element 84 can be designed as an outer guide track and / or cam track for positively guiding the first locking element 82. Furthermore, the locking arrangement 80 can have an end stop 86. In the initial position P1, the first locking element 82 is arranged in a gap between the second locking element 84 and the end stop 86 and is secured against unintentional rotation.

[0050] The locking device 80 is, for example, a loss prevention device and / or a transport safety device. By means of the locking device 80, the compensating elements 30, 40 are secured against movement relative to the base element 20 in order to prevent unintentional movement of the compensating elements 30, 40 relative to the base element 20 during transport of the device 10.

[0051] During assembly of the device 10 and transmission of torque from the screw element 16 to the second compensating element 40, the latter is rotated such that the first locking element 82 slides over the second locking element 84 by overcoming a predetermined locking torque, thereby releasing the movement of the second compensating element 40 and thus of the first compensating element 30 from the base element 20. The predetermined locking torque is less than the torque that can be transmitted from the screw element 16 via the drive element 50 to the second compensating element 40.

[0052] Fig. Figures 4 to 7 schematically show in perspective views individual device elements of the device 10 according to Fig. 1. In particular, they show Fig. 4 the second balancing element 40, for example designed as main balancing element 40a, Fig. 5 the plant section 46 of the second compensating element 40, Fig. 6 the first compensating element 30 designed as an intermediate element 30a and Fig. 7 the basic element 20.

[0053] Fig. Figure 8 schematically shows a second embodiment of a device 100 according to the invention for compensating for tolerances between components 12, 14, 18 to be connected to each other by means of a screw element 16.

[0054] In the illustrated embodiment, two components 12, 14 are to be connected to a third component 18, for example an intermediate customer interface.

[0055] The device 100 is designed to compensate for a first joining gap between a first component 12 and the customer interface, in particular the third component 18, and a second joining gap between a second component 14 and the customer interface, in particular the third component 18.

[0056] A screw element 16 for connecting components 12, 14, 18 can be passed through the device 100 (indicated by a dashed line). The device 100 can comprise at least one previously described holding device 70 and a locking arrangement 80.

[0057] The device 100 comprises a base element 200. The device 100 comprises a first compensating element 300, which is movable by rotation relative to the base element 200. The first compensating element 300 is arranged coaxially with the base element 200. The device 100 comprises a second compensating element 400, which is also movable by rotation relative to the base element 200. The second compensating element 400 is arranged coaxially with the base element 200. In particular, the base element 200 and the compensating elements 300, 400 are movable coaxially with each other and axially relative to each other, for example, telescopically.

[0058] The basic element 200 is designed as a double ring. The first compensating element 300 is designed as a ring. The second compensating element 400 is designed as a double ring. Each double ring consists of an inner ring 202, 402, an outer ring 204, 404, and a connecting section 206, 406. For example, the respective connecting section 206, 406 forms a connecting web.

[0059] The base element 200 comprises a cavity 22 in which the first compensating element 300 and the second compensating element 400 are received in a starting position P1. In particular, the compensating elements 300 and 400 are arranged in the inner ring 202 of the base element 200. The first compensating element 300 and the second compensating element 400 are each movable relative to the base element 200 in two different directions of movement, in particular, extendable.

[0060] The compensating elements 300 and 400 are designed to engage, in particular frictionally engage, with the screw element 16. The first compensating element 300 comprises a cavity 32 in which at least one drive element 50a is arranged. The second compensating element 400 comprises a cavity 42 in which a drive element 50b is arranged. The drive elements 50a and 50b are designed to each establish a connection with the screw element 16 upon insertion.

[0061] The first compensating element 300 can be designed as a hollow cylindrical compensating element 300 that engages or can be brought into thread engagement with a base element 20, and which, by rotating relative to the base element 200, moves from the initial position P1 to a compensating position P2, as shown in Fig. As shown in Figure 10, the base element 200 is axially movable. For this purpose, the base element 200 has, in sections, first threads 208 on the inner side of the inner ring 202, which engage with external threads 302 of the first compensating element 300. The inner side of the inner ring 202 is partially smooth-walled to accommodate the inner ring 402 of the second compensating element 400.

[0062] The second compensating element 400 can also be designed as a hollow cylindrical compensating element 400 that engages or can be brought into thread engagement with the base element 200 and can be axially moved from the initial position P1 to a compensating position P2 by rotating it relative to the base element 200. For this purpose, the base element 200 has second threads 210 on an outer side of the inner ring 202, which engage with internal threads 408 of the second compensating element 400.

[0063] The holding device 70 is designed, for example, as a clamping device, screwing device and / or adhesive device. The holding device 70 is connected to the outer ring 204 of the base element 200 and is configured to pre-fix the device 100 at a customer interface or on the third component 18.

[0064] Fig. Figure 9 shows schematically in perspective view the device 100 in the starting position P1 and Fig. Figure 10 shows schematically in perspective view the device 100 in the compensation position P2.

[0065] Fig. Figure 11 schematically shows in sectional view a process for compensating tolerances between components 12, 14, 18 to be joined together, in which the device 100 is moved from the starting position P1 to the compensation position P2.

[0066] When the screw element 16 is tightened, in a first step the first compensating element 300 is rotated relative to the base element 200 via the drive element 50a, which is connected between the screw element 16 and the first compensating element 300. This rotation causes the first compensating element 300 to move axially from its initial position P1 to the base element 200, for example, extending it out of the base element 200, until it reaches its compensating position P2. In a second step, further rotation of the screw element 16 causes it to engage with the drive element 50b of the second compensating element 400, specifically through frictional engagement.As the screw element 16 is further tightened, the second compensating element 400 is rotated relative to the base element 200 via the drive element 50b connected between the screw element 16 and the second compensating element 400, and is thereby moved axially from its initial position P1 to the base element 200, for example, extended out of the base element 200, until it reaches its compensating position P2.

[0067] The torque is transmitted to the first compensating element 300 and then to the second compensating element 400 until a respective section 304, 406 of the first compensating element 300 and of the second compensating element 400 is in contact with one of the components 12, 14.

[0068] A nut 162 can be provided on the lower component 12 for fixing the screw element 16.

[0069] The turning direction D1 of the first compensating element 300 is opposite to the turning direction D2 of the second compensating element 400. When the screwing element 16 is screwed in, the first compensating element 300 is initially moved out of the base element 200 in a turning direction D1, for example, upwards. As the screwing element 16 is screwed in further, the second compensating element 400 is moved out of the base element 200 in a turning direction D2, for example, downwards. This allows three components 12, 14, 18, arranged at a distance from each other, to be connected and aligned with each other.
