Description

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

[0002] Such a tolerance compensation device is generally known and is used, for example, in vehicle construction, particularly when two components need to be bolted together across a joint gap subject to tolerances. The tolerance compensation device is placed between the components to be joined, and a screw element for screwing the components together, such as a screw or threaded bolt, is passed through appropriately provided openings in the components and through the tolerance compensation device.When screwing the screw element, the compensating element is rotated relative to the base element via 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, moved 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 joint gap.

[0003] The object of the present invention is to provide a device for compensating tolerances between at least two components to be connected to one another, which device is improved compared to the prior art.

[0004] The problem is solved by the features specified in claim 1.

[0005] Advantageous embodiments of the invention are the subject of the subclaims.

[0006] The object is achieved by a device according to the invention for compensating 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 engaged, for example in threaded engagement, and a second compensating element connected to the first compensating element or to the base element, in particular engaged, for example in threaded engagement, and the first compensating element and the second compensating element are each movable from an initial position into a compensating position by rotation relative to the base element and relative to one another. In particular, the compensating elements and the base element are designed to be telescopically movable relative to one another and / or into one another.

[0007] The advantages achieved by the invention are, in particular, 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, whereby comparatively large tolerances between at least two components can be compensated. Furthermore, no compensation path, in particular the tolerance compensation path, of the device needs to be shortened in order to achieve a comparatively smaller and more compact design of the device.

[0008] The device is, for example, a tolerance compensation device, in particular for compensating tolerances when attaching a component to a part with a bore or blind hole. Tolerance compensation devices are part of fastening elements for attaching components and parts to one another, for example in motor vehicles. For example, such tolerance compensation devices are pressed into one of the parts. In particular, the device is an automatic tolerance compensation system.

[0009] 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 designed to be axially movable relative to the base element. The first compensating element is movably arranged in a cavity of the base element.

[0010] The first compensating element can be designed as a hollow cylindrical compensating element which is in threaded engagement with a base element or can be brought into threaded engagement with it and which can be moved axially from the starting position into a compensating position by rotation relative to the base element.

[0011] 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.

[0012] The adjustment elements' unscrewing directions are identical. Both unscrewing directions of the adjustment elements correspond, for example, to an upward or downward movement out of the base element. The first adjustment element and the second adjustment element can be extended upward or downward from the base element, for example, by screwing or unscrewing.

[0013] The second compensating element is movably arranged in 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 one another. The second compensating element can be designed as a hollow cylindrical compensating element that is or can be threadedly engaged with the first compensating element and that can be axially moved from the starting position into a compensating position by rotation relative to the first compensating element and thus to the base element. The second compensating element can in particular form a main compensating element.

[0014] When the screw element is screwed in, the second compensating element can first be moved relative to the first compensating element, in particular, unscrewed. Subsequently, by further screwing in the screw element, the first compensating element can be moved relative to the base element, in particular, unscrewed from the base element.

[0015] The first compensating element can be used as an additional intermediate element between the base element and the second compensating element in order to compensate for larger tolerances without having to change the overall height, technical and mechanical properties of the device.

[0016] According to the previous description, it can be summarized that the invention relates to a first embodiment, according to which a device for compensating tolerances between two components to be connected to one another by means of a screw element comprises at least - a basic element, - a first compensating element connected to, in particular engaged with, the base element and - comprises a second compensating element that is connected, in particular engaged, with the first compensating element, - wherein the first compensating element is movable relative to the base element by rotation therefrom, in particular movable out or unscrewed, 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 can be moved out or rotated out.

[0017] 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.

[0018] This embodiment relates to a second embodiment, according to which a device for compensating tolerances between three components to be connected to one another by means of a screw element comprises at least - a basic element, - a first compensating element connected to, in particular engaged with, the base element and - comprises a second compensating element that is connected, in particular engaged, with the base element or can be brought into contact with it, - whereby the compensating elements are assigned to two opposite end faces of the base element, - wherein the first compensating element is movable relative to the base element by rotation therefrom, in particular movable out or unscrewed, and - the second compensating element can also be moved out of the base element by rotating it relative to the base element, in particular can be moved out or rotated out.

[0019] The unscrewing directions of the compensating elements are opposite. A first unscrewing direction of the first compensating element corresponds, for example, to an upward movement out of the base element. A second unscrewing direction of the second compensating element corresponds, for example, to a downward movement out of the base element. The first compensating element can be extended upwards from the base element, for example, by screwing or unscrewing. The second compensating element can be extended downwards from the base element, for example, by screwing or unscrewing.

[0020] The second compensating element can be adjusted relative to the base element to compensate for tolerances between two components. The second compensating element is designed to be axially movable relative to the base element and the first compensating element. This allows tolerances between a total of three components to be compensated. A tolerance above the base element can be compensated by axially adjusting the first compensating element, and a tolerance below the base element can be compensated by axially adjusting the second compensating element. The base element and the compensating elements are arranged in an interconnected manner. The compensating elements and the base element are designed to be telescopically movable or movable within one another.The second compensating element can be designed as a hollow cylindrical compensating element which is in threaded engagement with a base element or can be brought into threaded engagement with it and which can be moved axially from the starting position into a compensating position by rotation relative to the base element.

[0021] The base element and the second compensating element can each be designed as a double ring. The respective double ring can consist of an inner ring, an outer ring, and a contact section connecting the rings. The first compensating element can be designed as a single ring.

[0022] The double rings can be nested in such a way that the outer ring of the second compensating element is arranged between the inner ring and the outer ring of the base element. At the same time, the inner ring of the base element can be arranged 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 arranged in the cavity of the base element. This can create a nested arrangement that does not affect the overall height of the device. Furthermore, the device can also be designed relatively compactly with three components.

[0023] When screwing in the screw element, one of the compensating elements, which first engages with the screw element, can be axially moved, in particular unscrewed, from its initial position into a compensating position relative to the base element. Subsequently, by further screwing in the screw element through the other of the compensating elements, this compensating element can be moved, in particular unscrewed, from its initial position into a compensating position relative to the base element.

[0025] Corresponding parts are provided with the same reference numerals in all figures.

[0026] Fig. 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.

[0027] The device 10 can, for example, be a tolerance compensation device and / or a tolerance balancing device.

[0028] A screw element 16 for connecting the components 12, 14 can be passed through the device 10 (also indicated by a dashed line).

[0029] 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 to 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 base element 20 and to the base element 20. The second compensating element 40 is arranged coaxially to the base element 20. In particular, the base element 20 and the compensating elements 30, 40 are arranged coaxially to one another and axially movable relative to one another.

[0030] 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, 40 are each designed to be telescopically movable, in particular displaceable, relative to one another and relative to the base element 20.

[0031] 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 designed to engage, in particular frictionally engage, the screw element 16. The second compensating element 40 comprises a cavity 42 in which at least one driving element 50, as shown in Fig. 3, is arranged to form a connection with the screw element 16 upon insertion. The driving element 50 is supported, for example, on a circumferential surface of the inner cavity 42 of the second compensating element 40. The driving element 50 can be a driving spring or another spring element.

[0032] The first compensating element 30 can be designed as a hollow cylindrical compensating element 30 which is in threaded engagement with a base element 20 or can be brought into threaded engagement with the base element 20 and which can be axially moved from the starting position P1 into a compensating position P2 by rotation relative to the base element 20.

[0033] The second compensating element 40 can be designed as a hollow cylindrical compensating element 40 which is in threaded engagement with the first compensating element 30 or can be brought into threaded engagement with the first compensating element 30 and which can be axially moved from the starting position P1 into a compensating position P2 by rotation relative to the first compensating element 30 and thus to the base element 20.

[0034] The compensating elements 30, 40 and the base element 20 are axially movable, in particular telescopically, towards each other and / or into each other, in particular displaceable.

[0035] This allows different, for example comparatively larger tolerances and longer compensation paths between two components 12, 14 to be compensated for, while maintaining a desired compact height of the device 10.

[0036] 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.

[0037] Fig. 2 shows schematically in section the device 10 in the starting position P1 and Fig. 3 shows a schematic sectional view of the device 10 in the compensation position P2.

[0038] 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) of the first component 12.

[0039] In this case, the screw element 16 can engage, for example frictionally engage, with the driving 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 then, by adjusting, in particular rotating, the second compensating element 40, to the first compensating element 30. By adjusting, in particular rotating, the second compensating element 40, the latter is moved, in particular extended, from the first compensating element 30, which is designed as an intermediate element 30a. The resulting torque is transmitted to the first compensating element 30, which is designed as an intermediate element 30a, whereby the first compensating element 30 is moved, in particular extended, relative to the base element 20.

[0040] The base element 20 may include an internal thread 24. The first compensating element 30 may 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 may include an external thread 44 corresponding to the internal thread 36 of the first compensating element 30.

[0041] When screwing the screw element 16, the second compensating element 40 is rotated relative to the first compensating element 30 via the driving element 50 connected between the screw element 16 and the second compensating element 40 and is thereby moved from its initial position P1, shown in Fig. 2, is moved axially relative to the base element 20, for example, moved out of the base element 20, until it reaches its compensation position P2. By further rotating the screw element 16 and the second compensation element 40, the torque is transmitted to the first compensation element 30, designed as an intermediate element 30a, whereby the first compensation element 30 is rotated relative to the base element 20 and moved from its starting position P1 into its compensation position P2 until the second compensation element 40, in particular a contact section 46 of the second compensation element 40 arranged on the end face, rests against one of the components 12, 14. In this way, for example, a joint gap can be compensated or bridged.

[0042] As in Fig. 3, the unscrewing directions D1, D2 of the compensating elements 30, 40 are identical. Unscrewing directions D1, D2 are understood to mean a screwing direction, in particular an unscrewing direction. When screwing the screw element 16 into the second compensating element 40, the second compensating element 40 can be moved, in particular unscrewed, from the first compensating element 30 in the unscrewing direction D2. The first compensating element 30 can be moved, in particular unscrewed, from the base element 20 simultaneously or subsequently in the unscrewing direction D1, which corresponds to the unscrewing direction D2 of the second compensating element 40.

[0043] The contact section 46 is, for example, a flange section and / or a stop ring.

[0044] The device 10 comprises at least one anti-rotation device 60, as shown in Fig. 3. The anti-rotation protection 60 can comprise a number of anti-rotation elements 62, 64, 66, 68. A first anti-rotation element 62 can be arranged at a front end 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 one another and prevent the first compensating element 30 from being unscrewed from the base element 20.

[0045] 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 on a front end 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. In the compensating position P2, the anti-rotation elements 64, 68 engage or abut with one another and prevent the second compensating element 40 from rotating out of the first compensating element 30.

[0046] The anti-rotation elements 62, 64, 66, 68 can form corresponding locking elements and counter-locking elements. For example, one of the anti-rotation elements 62, 64, 66, 68 can be designed as a pressed-in ring or a stamped thread or a thread undercut. The other anti-rotation element 62, 64, 66, 68 can be designed as a corresponding counter-element, for example, as a stop, a groove, an undercut, or an embossed portion.

[0047] 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 in a recess 72 of the holding device 70 by means of a positive connection and / or frictional connection. The base element 20 is mounted in the holding device 70, secured against axial movement and thus fixedly arranged. To fix 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 holding arms 74.The holding arms 74 can each be designed in the form of a clip, for example an L-shaped or J-shaped clip, or as a folding hinge or a bayonet device.

[0048] The device 10 may further comprise, for example, a securing arrangement 80 as shown in Fig. 1, for securing the compensating elements 30, 40 against movement relative to the base element 20. The securing arrangement 80 comprises a first securing element 82 formed on an outer circumference, for example on an edge of the contact section 46 of the second compensating element 40. The first securing element 82 is integrally formed on the second compensating element 40. The first securing element 82 is designed as a protruding pin, cam, or nose. Furthermore, the securing arrangement 80 comprises a second securing element 84 arranged on the base element 20 and / or on the holding device 70. The second securing element 84 can be integrally formed on the base element 20 and / or on the holding device 70. The second securing element 84 is, for example, a counter-element corresponding to the first securing element 82. The second securing element 84 can be designed as a stop, pin, cam, or nose.For example, the second securing element 84 can be designed as an outer guide track and / or cam track for positively guiding the first securing element 82. Furthermore, the securing arrangement 80 can have an end stop 86. In the initial position P1, the first securing element 82 is arranged in a gap between the second securing element 84 and the end stop 86 and is secured against unintentional rotation.

[0049] The securing arrangement 80 is, for example, a loss prevention device and / or a transport lock. By means of the securing arrangement 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.

[0050] When the device 10 is assembled and the torque is transmitted from the screw element 16 to the second compensating element 40, the latter is rotated such that the first securing element 82 slides over the second securing element 84, overcoming a predetermined securing torque and releasing the movement of the second compensating element 40 and thus of the first compensating element 30 out of the base element 20. The predetermined securing torque is smaller than the torque that can be transmitted from the screw element 16 to the second compensating element 40 via the driving element 50.

[0051] Fig. 4 to 7 show schematically in perspective views individual device elements of the device 10 according to Fig. 1. In particular, Fig. 4 the second compensating element 40, designed for example as a main compensating element 40a, Fig. 5 the contact 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.

[0052] Fig. Fig. 8 shows a schematic sectional view of a second embodiment of a device 100 according to the invention for compensating tolerances between components 12, 14, 18 to be connected to one another by means of a screw element 16.

[0053] In the illustrated embodiment, two components 12, 14 are to be connected to a third component 18, for example an intermediate customer interface.

[0054] 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.

[0055] A screw element 16 for connecting the 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 securing arrangement 80.

[0056] The device 100 comprises a base element 200. The device 100 comprises a first compensating element 300, which is movable relative to the base element 200 by rotation. 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 relative to the base element 200 by rotation. 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 one another and axially relative to one another, for example, telescopically.

[0057] The base 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 is formed from an inner ring 202, 402, an outer ring 204, 404, and a contact section 206, 406 connecting these rings. For example, the respective contact section 206, 406 forms a connecting web.

[0058] The base element 200 comprises a cavity 22 in which the first compensating element 300 and the second compensating element 400 are received in an initial position P1. In particular, the compensating elements 300, 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, in particular extendable.

[0059] The compensating elements 300, 400 are designed to engage, in particular frictionally engage, the screw element 16. The first compensating element 300 comprises a cavity 32 in which at least one driver element 50a is arranged. The second compensating element 400 comprises a cavity 42 in which a driver element 50b is arranged. The driver elements 50a, 50b are each provided to form a connection with the screw element 16 upon insertion.

[0060] The first compensating element 300 can be designed as a hollow cylindrical compensating element 300 which is in threaded engagement with a base element 20 or can be brought into threaded engagement with the base element 200 and which can be moved by rotation relative to the base element 200 from the initial position P1 into a compensating position P2, as in Fig. 10, is axially movable. For this purpose, the base element 200 has, in sections, first threads 208 on an inner side of the inner ring 202, which threadably engage with external threads 302 of the first compensating element 300. The inner side of the inner ring 202 is designed with smooth walls in sections to accommodate the inner ring 402 of the second compensating element 400.

[0061] The second compensating element 400 can also be designed as a hollow cylindrical compensating element 400 that is or can be threadedly engaged with the base element 200 and that can be axially moved from the starting position P1 into a compensating position P2 by rotation 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 threads engage with internal threads 408 of the second compensating element 400.

[0062] The holding device 70 is designed, for example, as a clamping device, screw 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 to a customer interface or to the third component 18.

[0063] Fig. Figure 9 shows schematically in perspective view the device 100 in the starting position P1 and Fig. 10 shows schematically in perspective view the device 100 in the compensation position P2.

[0064] Fig. 11 shows a schematic sectional view of 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.

[0065] When screwing the screw element 16, in a first step, the first compensating element 300 is rotated relative to the base element 200 via the driver element 50a connected between the screw element 16 and the first compensating element 300, and is thereby moved axially from its initial position P1 toward the base element 200, for example, moved out of the base element 200, until it reaches its compensation position P2. By further rotating the screw element 16, the screw element 16 engages, in particular frictionally, the driver element 50b of the second compensating element 400 in a second step.When the screw element 16 is screwed further, the second compensating element 400 is rotated relative to the base element 200 via the driving element 50b connected between the screw element 16 and the second compensating element 400 and is thereby moved axially from its starting position P1 to the base element 200, for example moved out of the base element 200, until it reaches its compensating position P2.

[0066] The torque is transmitted to the first compensating element 300 and then to the second compensating element 400 until a respective contact section 304, 406 of the first compensating element 300 and the second compensating element 400 rests against one of the components 12, 14.

[0067] A nut 162 may be provided on the lower component 12 for fixing the screw element 16.

[0068] The unscrewing direction D1 of the first compensating element 300 is opposite to the unscrewing direction D2 of the second compensating element 400. When screwing in the screw element 16, the first compensating element 300 is first moved in an upward unscrewing direction D1 from the base element 200, for example. As the screw element 16 is further screwed in, the second compensating element 400 is moved in a downward unscrewing direction D2 from the base element 200, for example. This allows three components 12, 14, 18 arranged at a distance from one another to be connected to one another and aligned with one another.
