Description

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

The invention further relates to a method for mounting such a device.

Such a tolerance compensation device is basically known and is used, for example, in vehicle construction, in particular when it comes to screwing two components together over a tolerance-related joint gap. The tolerance compensation device is arranged for this purpose between the components to be joined, and a screw for screwing the components, for. As a screw or a threaded bolt is passed through corresponding openings provided in the components and by the tolerance compensation device. When screwing the screw, the compensating element is rotated relative to the base element via a driving spring connected between the screw and the compensating element and thereby moved axially from its initial position to the base element, for. B. moved out of the base until it reaches its balancing position, in which abut the base member and the compensation element respectively on one of the components and so bridge the joint gap.

Furthermore, devices for compensating for tolerances at a distance between a roof plate (= first component) of the vehicle and an underlying support structure (= second component) in the direction of a longitudinal central axis are particularly known for mounting a rail to a roof of a vehicle. For this purpose, the device is clipped by means of a retaining element in a recess provided for the roof panel and the compensation element as far as unscrewed from the base until it is supported at the underlying support structure and the roof plate under cross-clip arms of the support member are supported upwardly on the roof panel. The retaining element takes on the first component between the clip arm and an abutment which extends radially outward from the base body and is inclined in the direction of the clip arms. A portion of the base protrudes upward beyond the roof plate and forms a contact surface for the rail to be mounted. In order for the device to be easily clipped into the recess of the roof skin, the clip arms of the holding element are made comparatively soft. At the same time the device should be firmly supported in an assembled state on both components, which is why the compensation element is even further rotated out of the base element when it is already in engagement with the support structure, resulting in a yielding of the clip arms can result. To avoid this, an expansion is provided, which prevents deflection of the clip arm from its rest position in a direction away from the body.

The invention is based on the object to provide a comparison with the prior art improved device for compensating for tolerances between two components to be joined together and an improved method for mounting such a device.

With regard to the device, the object is achieved by the features specified in claim 1 and in terms of the method by the features specified in claim 12.

Advantageous embodiments of the invention are the subject of the dependent claims.

The device according to the invention for compensating for tolerances between a first component and a second component comprises a hollow cylindrical basic element defining a longitudinal center axis, a hollow cylindrical compensating element threadably engaged with the base element and a holding element fixedly connected to the base element or integrally formed therewith for holding the element Basic element on the first component. The retaining element is designed for clipping into a recess of the first component and comprises at least two holding structures, in particular arranged on opposite sides of a holding element base body. In this case, a first support structure has at least one bending-resistant lower support arm and at least one upper support arm, wherein a free space for receiving a recess bounding the first portion of the first component is formed between the support arms. A second holding structure has at least one bending-resistant lower supporting arm and at least one resiliently designed upper supporting arm, wherein between the supporting arms a free space for receiving a recess bounding the second portion of the first component is formed.

The device allows due to the resiliently formed upper support arm of the second support structure and a lateral deflection of the same during assembly of the device in the recess of the first component that the lower stable rigidly formed support arms of the holding element under the first component, such as a metal sheet, in particular a roof panel , can dive. With relief of the spring-trained upper support arm by means of this and the upper support arm of the first support structure a support on the component, for example on a flexible roof skin. That is, a clip function of the device is decoupled from a support function of the device below the first component. Due to the advantageous support and the function of the device during assembly in the recess deflections of thin components, such as sheets, which are caused for example by sealing forces under a roof rail, can be effectively avoided.

In particular, in an application of the device for producing a screw surface for a roof rail of a vehicle, the device allows the flexible roof not visibly deformed, while at the same time a high rigidity in the support of the device is achieved under the roof by means of rigid trained lower support arms.

Compared to known from the prior art devices to compensate for tolerances, in which so-called clip-under geometries are provided with clip arms, which are supported upon activation of the compensating element under the flexible roof and due to the functionality of the clip arms, in particular the bending and resilience and In particular, the radially necessary mobility of the device in the recess of the first component, lead to a large overall height of the device, the claimed device is characterized by a particularly low height. At the same time, particularly small tolerances can be realized, so that, for example, in the application of the device for producing a screw surface for a roof rail, particularly small clearances and easy securing of a sealing function can be realized.

Due to the flat design of the device with low height can on the one hand a particularly high power density, d. H. a high performance with a small size, can be achieved. On the other hand, in the application of the device for producing the screw surface for a roof rail, a distance between a roof and a support structure can be kept small, so that a very efficient use of space can be realized.

According to a possible embodiment of the device, the resiliently formed upper support arm has at least two limbs, wherein a first limb delimits the free space on an upper side and a second limb delimits the free space on one on the holding element and on an end wall of the second portion of the limited first side of the device. As a result, the spring functionality of the support arm is realized with simultaneous Abstützfunktionalität the support arm for a top of the first component in a particularly simple, reliable and kleinbauender way.

According to a further possible embodiment of the device, the second leg of the resiliently formed upper support arm is resiliently connected to the holding element base body. As a result, a particularly favorable travel for the assembly of the device can be realized.

According to a possible further development of the device, in the relaxed state of the resiliently formed upper support arm, a bearing surface of the first leg of the resiliently formed upper support arm for abutment against an upper side of the second portion of the first component extends substantially parallel to an abutment against an underside of the second portion the first component provided contact surface of the lower support arm. In the tensioned state of the spring-trained upper support arm, a distance between the first leg of the spring-trained upper support arm and the contact surface of the lower support arm increases starting from a holding element base body side facing in the direction of the holding element base body side facing away. This design allows reliably a simple introduction of the device into the recess of the first component and in a mounted end position of the device a reliable support thereof on the first component.

In a possible embodiment of the device, in the tensioned state of the resiliently formed upper support arm, a distance between the side of the second leg provided for abutment with the end face of the second portion of the first component and a surface of the first support structure formed between the support arms of the first support structure is smaller in the relaxed state of the spring-trained upper support arm. In this way, in a simple manner, a length extension of the device in the tensioned state of the upper support arm can be reduced such that insertion of the device into the recess with little effort and thus with little risk of deformation of the first component, such as the roof done.

In a further possible embodiment of the device in the relaxed state of the resiliently formed upper support arm, a distance between the provided for abutment on the end side of the second portion of the first component side of the second leg and a formed between the support arms of the first support structure surface of the first support structure larger as a Distance between the two sections of the recess. Alternatively, this distance corresponds to the distance between the two subregions of the recess. In this way, a stable, in particular non-rotating seat of the holding element and thus the device can be achieved within the recess.

Alternatively, in the relaxed state of the resiliently formed upper support arm, the distance between the side of the second leg provided for abutment with the end face of the second portion of the first component and the area of the first support structure formed between the support arms of the first support structure is smaller than the distance between the two portions of the recess, wherein the amount is smaller than a length of the upper support arm of the first support structure. Thus, it is possible to move the device, in particular to a tolerance compensation, within the recess. At the same time a "slipping" of the upper support arms through the recess and thus a "falling in" of the device in a between the components, for example, between the roof and the support structure, formed cavity is effectively avoided.

In a possible development of the device, the holding element base body completely surrounds an outer circumferential surface of the base element. Thus, the base member is securely and stably held within the support member.

A possible embodiment of the device provides that the holding element base body and the base element are connected to each other by means of at least one latching connection form-fitting and free of play. As a result, the base element is securely and easily attached to the support member. Due to the backlash-free and thus at least almost tolerance-free alignment of the base element and retaining element to each other and consequently also between the base element and compensating element, a tolerance of the entire device can be minimized and the high power density can be achieved.

Particularly suitable for producing such a latching connection, resilient clip elements arranged on the holding element, in particular clip elements projecting beyond a contact surface of the holding element on the base element, and at least one latching structure formed on the base element, into which the clip elements engage.

A further possible embodiment of the device provides that the compensation element is movable by rotation relative to the base element from a starting position into a compensating position, wherein a through an inner cavity of the base member and an inner cavity of the compensating member extending through screw to a screw with a Threaded element is provided, wherein in the inner cavity of the compensating element, a driving element is arranged, which is in frictional engagement with the guided through the cavities screw member such that a torque exerted by the screw torque can be transmitted to the compensating element. This makes it possible in a simple and reliable way to compensate for a space between the first and second component space.

In one possible embodiment of the device, the device is arranged in the recess of the first component for tolerance compensation between the two components and an attachment of another component, such as a roof rail on the two components, and a screw from below through an opening of the second component, the Device and an opening of the first component passed. In this case, the screw gets into engagement with the driving element and a on the other component, such as a roof rail, located threaded element. If the screw element is screwed for screwing the components, for example clockwise, a torque is transmitted to the compensating element by the driving element, which causes a rotation of the compensating element relative to the base element, whereby the compensating element moves downwards along a longitudinal center axis out of the base element. As soon as the compensating element has been rotated out of the base element so far that a contact section thereof abuts against the second component, a frictional torque between the second component and the abutment section exceeds the torque transmittable by the carrier element and the compensating element is not further unscrewed from the base element. The compensating element has thus assumed a position designated as a compensating position, and the further component, for example the roof rail, can be fastened to the latter, in particular without deformation of the first and second component, for example of the roof and the carrier structure.

A possible development of the device provides that at least one securing arrangement for securing the compensating element against movement relative to the base element is provided. The securing arrangement forms a transport securing device for the device, in order to prevent inadvertent movement of the compensating element relative to the base element during transport of the same, for example to its installation location, which in the worst case can lead to separation of the compensating element and base element.

In order to realize a particularly reliable securing, the securing arrangement according to another possible embodiment of the device comprises a first securing element arranged on the compensating element and a second securing element mechanically coupled to the base element, wherein the securing elements are in mechanical engagement with one another in a secured position of the compensating element on the base element.

In the method according to the invention for mounting the device described above on the first component, the device is moved such that the recess defining second portion of the first component in the free space of the second support structure between the at least one rigidly formed lower support arm and the at least one resilient trained upper support arm is introduced until an end face of the second portion comes to rest on a free space on a side facing the retaining element facing the second leg of the resilient upper support arm. Subsequently, a first force acting essentially perpendicularly on the end face is exerted on the device in such a way that the second leg moves in the direction of the in particular opposite first holding structure and the spring-trained upper support arm is tensioned. Subsequently, while maintaining the first force, a second force acting essentially perpendicularly to the first force is exerted on the device in the region of the first holding structure until the at least one lower support arm of the first holding structure is arranged below the first portion of the first component bounding the recess and at least one upper support arm of the first support structure is arranged above the first part of the first component bounding the recess. Subsequently, the first force is released and the recess limiting first portion of the first component is guided in the free space located between the support arms of the first support structure.

The method, together with the device, makes it possible for the latter to be introduced into the recess in a simple manner and with little risk of deformation of the first component, for example of the roof, and attached to the first component in a simple manner.

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

1 shows a sectional view of a section of a vehicle 1 in the region of a fastening position of a roof rail 2 on a roof construction 3 as an exploded view.

The roof construction 3 comprises a first component designed as a roof or roof panel 4 and a second component formed as an underlying support structure 5 , Between the components 4 . 5 is a cavity H educated.

Between the first component 4 , ie the roof or roof sheet, and the roof rails 2 is a seal 15 arranged, which is an intrusion of foreign substances in between the first component 4 and the roof rails 2 prevented.

To a fastening of the roof rails 2 at the roof construction 3 is starting from a bottom, that is, starting from the second component 5 , a screw 6 through recesses A1 . A2 of the components 4 . 5 to one at the roof rails 2 on an underside of the same attached threaded element 7 , For example, a rivet nut, out and screwed with this.

To this gland, for example, by sealing forces of the seal 15 under the roof rails 2 caused deformation of the first component 4 , ie the roof, and the second component 5 , ie, to avoid the support structure, is between them in the cavity H a device 8th to compensate for tolerances between the components 4 . 5 arranged.

The device 8th comprises a hollow cylindrical basic element 9 which is a longitudinal central axis L has defined and on its inside, ie on a lateral surface of its inner cavity has a not shown internal thread. The internal thread has an external thread of the screw element 6 reverse orientation, in the present embodiment, for example, a left-hand thread. At one of the roof rails 2 facing side forms the basic element 9 a mounting surface for the roof rails 2 out.

The device 8th includes a greatly simplified and with the basic element 9 firmly connected or integrally formed with this holding element 12 for holding the primitive 9 and thus the device 8th on the first component 4 ,

The device 8th also includes an in 2 closer and with the basic element 9 Threaded hollow cylindrical compensating element 10 , which extends into the cavity of the basic element 9 extends in and has on its outside a not shown external thread. This external thread is connected to the internal thread of the basic element 9 engaged. By twisting the compensation element can be 10 along the longitudinal central axis L relative to the primitive 9 move, ie from the cavity of the primitive 9 out or screw into it.

In an internal cavity of the compensating element 10 is also in 2 closer illustrated and designed as a driving spring entrainment 11 arranged, which is located on a lateral surface of the cavity of the compensating element 10 supported. The entrainment element 11 stands with the through the device 8th ie through the cavities of primitive 9 and entrainment element 11 , guided by screw 6 in frictional engagement to one through the screw 6 applied torque to the compensation element 10 transferred to.

To the attachment of the roof rails 2 and for tolerance compensation between the components 4 . 5 becomes the device 8th in the recess A1 of the first component 4 arranged, in particular clipped into this. Subsequently, the screw is 6 from below through the recess A2 in the second component 5 and the device 8th passed. This will cause the screw 6 in engagement with the driving element 11 and at the roof railing 2 attached threaded element 7 , Will the screw 6 twisted, for example, to the right, so is by the driving element 11 a torque to the compensation element 10 transmitted, which is a rotation of the compensating element 10 relative to the primitive 9 causes, which causes the compensation element 10 along a longitudinal central axis L down from the primitive 9 moved out. Once the compensation element 10 so far from the basic element 9 turned out is that an investment section 10.1 the same on the second component 5 applied, exceeds a friction torque between the second component 5 and the investment section 10.1 that of the entrainment element 11 transferable torque and the compensation element 10 will not go further from the primitive 9 unscrewed. The compensation element 10 has thus taken a designated position as a compensation position and the roof rails 2 can without deformation of the first and second component 4 . 5 attached to these.

In 2 is an exploded view of a possible embodiment of the device 8th to compensate for tolerances between the first component 4 and the second component 5 shown. 3 shows a perspective view of the device 8th according to 2 and 4 a section of the device 8th according to 2 in the assembled state.

The predetermined securing torque is smaller than that of the screw 6 via the entrainment element 11 on the compensation element 10 transmittable torque. A vertical surface of the ramp-shaped second securing element 13.2 forms an end stop for the compensation element 10 at an opposite rotation.

In the 5 to 8th is a section of a vehicle 1 during assembly of the device 8th according to 2 shown at different times.
