Description

The invention relates to a device for compensating tolerances between two components to be connected to one another.

Such a tolerance compensation device is basically known and is used, for example, in vehicle construction, especially when it comes to screwing two components together across a tolerance-affected joining gap. For this purpose, the tolerance compensation device is arranged between the components to be connected, and a screw element for screwing the components, e.g. B. a screw or a 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 driving spring connected between the screw element and the compensating element and is thereby moved from its starting position axially to the base element, e.g. B. moved out of the base element until it reaches its compensation position, in which the base element and the compensation element each rest against one of the components and thus bridge the joining gap.

The object of the present invention is to provide an improved device compared to the prior art for compensating tolerances between two components to be connected to one another.

With regard to the device, the object is achieved according to the invention by the features specified in claim 1.

A first embodiment of the device according to the invention for compensating tolerances between two components to be connected to one another comprises at least one base element and a compensating element which is in threaded engagement with the base element and which can be moved from a starting position by rotating relative to the base element, the base element and the compensating element being such are placed one inside the other so that at least two, in particular three, coupling interfaces are formed between the base element and the compensating element.

The device enables a nested design with the same compensation path and a comparatively smaller, for example flatter, design.

The advantages achieved with the invention are, in particular, that by means of such a nested arrangement of the base element and the compensating element, the device can be made comparatively small and compact, whereby the load-bearing capacity of the device remains comparatively the same or can even be increased. In addition, no compensation path, in particular tolerance compensation path, of the device has to be shortened in order to achieve a comparatively smaller and more compact design of the device.

The additional load capacity that is provided by the at least two, in particular three, coupling interfaces and/or by the at least two, in particular three, threaded engagements can be used to achieve high strengths, for example when using materials other than metal. Known tolerance compensation systems are made of metal. The at least two coupling interfaces are formed at different areas between the base element and the compensation element. For example, the at least two coupling interfaces can extend essentially parallel and spaced apart from one another. In an embodiment with three coupling interfaces, all three coupling interfaces can be arranged parallel and spaced apart from one another.

Due to the nested design of the device, the compensating element and/or the base element can be made of plastic. Plastic enables a simplified manufacturing process and production process as well as cost savings. Furthermore, the compensating element and/or the base element can be designed to be comparatively weight-reduced.

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

In a possible embodiment, the compensating element is arranged on a first end face of the base element. The compensation element can be adjusted relative to the base element to compensate for tolerances between two components. The compensating element is arranged on the first end face of the base element, ie seen in the axial direction of the base element. The compensation element can be arranged to be axially movable relative to the base element.

The compensating element can be designed as a hollow cylindrical compensating element which is or can be brought into threaded engagement with a base element and which can be axially moved from the starting position into a compensating position by rotating relative to the base element.

For example, the coupling interfaces are spaced radially from one another. In particular, the coupling interfaces can be arranged essentially parallel to one another. The coupling interfaces can extend in the axial direction along the base element and/or the compensating element.

The coupling interfaces can be formed, for example, by several nested and axially movable threads of the base element and compensating element.

A further development of the invention provides that the base element and the compensating element are each designed as double rings. The respective double ring can be formed from an inner ring and an outer ring. The inner ring and outer ring of a respective double ring can be connected to one another via a connecting web.

For example, the compensating element designed as a double ring can have a movable, in particular axially movable, outer ring, which is provided with an internal thread and an external thread, and a movable, in particular axially movable, inner ring, which is provided with an external thread. In other words: The compensating element is arranged to be movable, for example axially movable relative to the fixed base element. The inner ring associated with the compensating element designed as a double ring and the associated outer ring are therefore also movable, in particular axially movable, arranged and designed as a movable inner ring and a movable outer ring.

The movable inner ring and the movable outer ring of the compensating element can be connected to one another via a contact section of the compensating element. For example, the contact section forms a connecting web. For example, the compensating element has the contact section on its upper side, which serves to support the device against a component and/or to support the compensating element on the base element. The movable inner ring and the movable outer ring of the compensating element can protrude from the contact section, for example protrude essentially vertically downwards.

For example, the base element can have a fixed, in particular a positionally fixed or stationary, outer ring which is provided with an internal thread, and a fixed, in particular a positionally fixed or stationary, inner ring which is provided with an external thread and an internal thread. In other words: The basic element is arranged in a fixed or fixed position, for example held. The inner ring associated with the basic element designed as a double ring and the associated outer ring are therefore also arranged in a fixed or fixed position and are designed as a fixed inner ring and a fixed outer ring.

The fixed inner ring and the fixed outer ring of the base element can be connected to one another via a contact section of the base element. For example, the contact section forms a connecting web. For example, the base element has the contact section on its underside, which serves to support the device against a component. The inner ring and the outer ring of the base element can protrude from the contact section, for example protrude essentially vertically upwards.

In the pre-assembled and/or assembled state of the device: The movable inner ring of the compensating element can be accommodated in a cavity of the fixed inner ring of the base element. The movable outer ring of the compensating element can be accommodated between the fixed inner ring of the base element and the fixed outer ring of the base element. This creates a nested and axially movable coupling of the base element and compensating element.

In a possible embodiment, the compensating element has an inner cavity in which at least one driving element is arranged for connection to a screw element. The inner cavity can be formed, for example, by an opening in the movable inner ring of the compensating element. The screw element can be in frictional engagement with the driving element in such a way that a torque exerted by the screw element can be transferred to the compensating element, in particular to its movable inner ring, and the compensating element also rotates, in particular by screwing it axially out of or into the base element.

In addition, the compensating element can have a threaded element for screwing to a screw element which extends through the fixed inner ring of the base element and the movable inner ring of the compensating element.

In addition, a securing arrangement can be provided for securing, in particular fixing, the compensating element against movement relative to the base element. The securing arrangement is used, for example, to secure transport and/or prevent loss.

A second embodiment of the device according to the invention for compensating tolerances between two components to be connected to one another comprises at least one base element and a compensating element which is in threaded engagement with the base element and which can be moved from a starting position by rotating relative to the base element, the base element having at least a first coupling space and has a second coupling space spaced radially from the first coupling space, and wherein the compensating element is designed to be in threaded engagement with the respective coupling space of the base element. The device enables a nested design with the same compensation path and a comparatively smaller, for example flatter, design.

For example, the first coupling space can be designed in the form of a recess which is provided with first threads. The second coupling space can be designed in the form of a further recess which is provided with second threads. The coupling spaces can, for example, extend in the axial direction along the base element. The coupling spaces can be spaced apart radially. The coupling spaces can be arranged to run parallel to one another.

The first threads can form an internal thread. The first threads can be brought or brought into thread engagement with the compensating element. The base element can, for example, be essentially hollow cylindrical and on its inside, i.e. H. have an internal thread on a lateral surface of its first, in particular inner, coupling space.

The second coupling space can be designed to be open on one end face of the base element and closed on the other end face of the base element. The second threads can, for example, form an internal thread. The basic element can be on an inside of the second coupling space, i.e. H. on a lateral surface of the second coupling space, have an internal thread.

For example, the second coupling space of the base element can have third threads. The third threads can form an external thread. The second threads and third threads can be arranged on opposite walls of the second coupling space. The second and/or third threads can be brought or brought into thread engagement with the compensating element.

In addition, the base element can have an, in particular fixed, inner ring and a, in particular fixed, outer ring, which are connected to one another on an end face via a contact section, for example a connecting web. The first coupling space is formed, for example, by the inner ring, for example by an inner opening in the inner ring, and/or in the inner ring. The second coupling space is arranged, for example, between the inner ring and the outer ring of the base element. The second coupling space is separated from the first coupling space by the inner ring. The second coupling space is enclosed radially outward by the outer ring of the base element. The inner ring and the outer ring are, for example, radially spaced apart from one another. For example, a first side, in particular the inside, of the inner ring of the base element can be provided with the first threads. A second side, in particular the outside, of the inner ring of the base element can be provided with the second threads. Alternatively or optionally, an inside of the outer ring of the base element can be provided with the third threads. The outside of the inner ring and the inside of the outer ring can face each other.

In addition, the compensating element can have an, in particular movable, inner ring and a, in particular movable, outer ring, which are connected to one another on an end face via a contact section, for example a connecting web. The inner ring and the outer ring of the compensating element are, for example, radially spaced apart from one another. The inner ring of the compensating element can be accommodated or accommodated in the first coupling space of the base element. The outer ring of the compensating element can be accommodated or accommodated in the second coupling space of the base element. The outer ring of the compensating element can be provided with an internal thread, for example corresponding to the second thread turns of the base element, and/or an external thread, for example corresponding to the third thread turns of the base element. The inner ring of the compensating element can be provided with an external thread, for example corresponding to the first thread turns of the base element.

In a possible embodiment, the base element and the compensating element are each designed as double rings.

In the pre-assembled and/or assembled state of the device, the inner ring of the compensating element is arranged in the first coupling space of the base element and is in threaded engagement with it. The outer ring of the compensating element is arranged in the second coupling space of the base element and is in threaded engagement with it.

1 shows schematically a sectional view of a first exemplary embodiment of a device 10 for compensating tolerances between two components B1, B2 to be connected to one another, which are indicated by dashed lines. The device 10 can be, for example, a tolerance compensation device and/or a tolerance compensation device.

1 For example, the device 10 can be represented in a state assembled with the components B1, B2.

The device 10 includes a base element 20. The device 10 includes a compensating element 30, which can be moved relative to the base element 20 by rotating it. The compensating element 30 is arranged coaxially to the base element 20.

In the exemplary embodiment shown, the basic element 20 has a first, for example upper, end face S1 and a second, for example lower, end face S2 opposite the first end face S1. The second end face S2 can rest on the first, lower component B1. The compensating element 30 is arranged on the first end face S1.

To connect, in particular screw, the components B1 and B2, the device 10 is arranged between them and a screw element 40 or another fastening element is passed from above through an opening in the second component B2, the device 10 and optionally additionally, for example, through an opening in the first component B1 passed through.

The screw element 40 can come into engagement, for example frictional engagement, with a driving element 50 which is arranged in the compensating element 30 in order to transmit a torque exerted by the screw element 40 to the compensating element 30.

When screwing the screw element 40, the compensating element 30 is rotated relative to the base element 20 via the driving element 50 connected between the screw element 40 and the compensating element 30 and thereby out of its starting position P1, shown in 4 , axially moved to the base element 20, e.g. B. moved out of the base element 20 until it reaches its compensation position P2, in which the base element 20 and the compensation element 30 each rest on one of the components B1, B2. This means, for example, that a joining gap can be compensated for or bridged.

The driving element 50 is supported, for example, on a lateral surface of an inner cavity H1 of the compensating element 30. The driving element 50 can be a driving spring or another spring element.

The base element 20 and the compensating element 30 are placed one inside the other in such a way that at least two coupling interfaces 61, 62 and/or 63 and preferably three coupling interfaces 61 to 63 are formed between the base element 20 and the compensating element 30.

In principle, the base element 20 and the compensating element 30 can have essentially the same shape. The base element 20 and the compensating element 30 can be designed to be complementary to one another. This allows a nested design with sufficient tolerance compensation and a high load capacity to be achieved.

The two coupling interfaces 61, 62 and optionally 63 are radially spaced apart from one another. The coupling interfaces 61, 62 and optionally 63 are formed by a plurality of nested and axially movable coupling sections, in particular axially movable threads 611, 612 and 621, 622 and optionally axially movable sliding sections 641, 642 of base element 20 and compensating element 30. The optional coupling interface 63 is formed, for example, by two suitable sliding surfaces for axial mobility of the sliding sections 641 and 642 relative to one another.

In other words: The compensating element 30 and the base element 20 include corresponding first threads 611, 612, which are aligned with one another and form a first coupling interface 61 in a threaded engagement. The compensating element 30 and the base element 20 include corresponding second threads 621, 622, which are aligned with one another and form a second coupling interface 62 in a threaded engagement. The balance member 30 and base member 20 include optional corresponding sliding portions 641, 642 aligned with each other and slidably coupled to form a third coupling interface 63.

The first coupling interface 61, the second coupling interface 62 and optionally the third coupling interface 63 run essentially parallel to one another in the axial direction along the base element 20 and the compensating element 30.

The base element 20 includes on its, in particular the second, lower end face S2, the contact section 23, which serves to support the device 10 against the first component B1. A fixed, in particular positionally fixed or positionally fixed, inner ring 21 and a fixed, in particular positionally fixed or positionally fixed, outer ring 22 of the base element 20 protrude from the contact section 23, for example essentially vertically upwards. The fixed inner ring 21 and the fixed outer ring 22 of the base element 20 are understood to mean in particular the fixed arrangement of the base element 20 in a holding device 70, in particular a holding clip or retaining ring, the base element 20 being in a recess 72 by means of a positive connection and/or friction connection Holding device 70 is held in a fixed position. In particular, the base element 20 is secured in the holding device 70 against axial movement and is therefore firmly arranged.

The holding device 70 serves to hold the base element 20 and the compensating element 30. To fix the device 10 in component B 1, the holding device 70 includes holding arms 71.

The compensating element 30 comprises on its end face, in particular the second end face S2 of the base element 20, opposite the end face the contact section 33, which serves to support the device 10 against the second component B2 and/or to support the compensating element 30 on the base element 20. The movable inner ring 31 and the movable outer ring 32 of the compensating element 30 protrude from the contact section 33, for example essentially vertically downwards. The movable inner ring 31 and movable outer ring 32 of the compensating element 30 are understood to mean, in particular, the mobility of the compensating element 30 itself, in particular its axial mobility relative to the base element 20.

The fixed inner ring 21 of the base element 20 is provided with the first threads 611 as internal threads. In the exemplary embodiment shown, the fixed inner ring 21 is further provided with the second threads 621 as external threads. This means that the fixed inner ring 21 of the base element 20 is provided with threads 611, 621 on both sides, for example on its inside and outside. An inside of the fixed outer ring 22, which faces the outside of the inner ring 21, can be flat and/or flat, for example flat, or have a different structure and/or profiling.

The movable outer ring 32 of the compensating element 30 is arranged between the fixed inner ring 21 of the base element 20 and the fixed outer ring 22 of the base element 20. This creates a nested and axially movable coupling of base element 20 and compensating element 30.

The device 10 further includes, for example, the holding device 70, which is coupled to the base element 20. The holding device 70 comprises, for example, at least one projecting holding arm 71, which supports the device 10 in the assembled state against the first component B1 and/or comes into locking engagement with the first component B1. The holding arm 71 can be designed as a J-clip, clamping element, latching element, hook element, spring element or as another corresponding holding element. The holding device 70 can have at least two holding arms 71 arranged opposite one another, as in 5 shown. The holding device 70 can also be a push-on locking element. The holding device 70 can be a bayonet device or a film hinge. The holding device 70 is arranged, for example, on the fixed outer ring 22 of the base element 20 and is connected to it at least non-positively, positively and/or materially. The holding device 70 can be integrated into the compensating element 30 or base element 20. The device 10 can include two holding devices 70. The holding device 70 can be arranged on the compensating element 30. An additional or alternative holding device 70 can be arranged on the base element 20. For example, the holding device 70 or the holding devices 70 can each be pushed laterally onto the compensating element 30 and/or onto the base element 20.
