Description

The invention relates to a radial compensation element and a device for compensating tolerances between a first component and a second component to be connected to this first component by means of a connecting bolt.

In a known compensating device of this type, a base element or body and an axial compensating element are formed by metallic threaded sleeves which are in left-hand thread engagement. A spring element is arranged in the axial compensating element, which creates a frictional connection between a connecting element passed through the compensating device and having a right-hand thread and the axial compensating element, so that when the connecting element is tightened, for example rotating, a torque is exerted on the axial compensating element, which causes the compensation element to be axially unscrewed from the base element counter to the direction of insertion of the connecting screw and thus compensates for axial tolerances.

The invention is based on the object of specifying a radial compensation element for compensating for tolerances in the radial direction and a device comprising such a radial compensation element.

The object is achieved according to the invention with a radial compensation element with the features of claim 1. With regard to the device, the object is achieved according to the invention by the features of patent claim 7.

Advantageous further developments of the invention are the subject of the dependent claims.

The radial compensation element according to the invention for compensating tolerances between a first component and a second component to be connected to this first component by means of a connecting bolt comprises a base body which has a receiving channel in which the connecting bolt can be received, the receiving channel being set up to receive the connecting bolt, and wherein the radial compensation element furthermore comprises a number of elastic elements which are set up to radially compensate tolerances between the connecting bolt and the first component.

The advantages achieved with the invention are, in particular, that such a radial compensation element with a receiving channel for the connecting bolt to be received and elastic elements compensating for radial tolerances enables both secure positioning, in particular centering, of the connecting bolt and preventing the connecting bolt from tilting in any mounting position. Particularly in the case of assembly in an inaccessible space in which the fitter has no direct view of the connecting bolt, incorrect positioning of the connecting bolt often leads to errors during assembly. The connecting bolt can be held in the receiving channel by means of a form fit or a force fit, in particular in a press fit.

The radial compensation element is designed in particular as an elastic contour element or an elastic ring body. The elastic radial compensation element is designed in particular in such a way that the actual function, d. H. the compensation of axial tolerances between the first component and the second component is not impaired by the elastic radial compensation element. Therefore, an elasticity of the radial compensation element is advantageously specified in such a way that a force which is required for the elastic deformation of the radial compensation element or a region of the radial compensation element is just sufficiently large to hold the connecting bolt in a safe, in particular in a nominal position, against its weight. The elastic centering arrangement is thus advantageously designed in such a way that the spring forces of the radial compensation element or centering element resulting from the elasticity only compensate for the weight of the connecting bolt and thus keep the connecting bolt in balance in the nominal position, in particular on the first component. In other words: by means of the radial compensating element, the connecting bolt is held in the first component in a form-fitting or force-fitting manner, in particular pressed, braced or clamped.

One possible embodiment provides that the base body has an annular shape from which the elastic elements protrude radially outward at an acute angle.

The plurality of elastic elements, also called elastic centering elements, enables the connecting bolt to be supported in the radial direction and thus in the direction of the first component, whereby the centering in the nominal position is ensured, for example, independently of a respective installation position of an overall device. The connecting bolt is thus advantageously centered in the nominal position in every possible installation position of the device. Furthermore, for example, no exact alignment of the radial compensation element and / or the connecting bolt is required in order to ensure, for example, that the weight of the connecting bolt due to the shape or Force fit seat, in particular a press fit, of the connecting bolt in the radial compensation element and is supported radially by the elastic elements of the radial compensation element. It is therefore also provided that the elastic elements, in particular centering elements, are arranged or formed distributed over a circumference, in particular an outer circumference, of the base body, in particular an annular and / or hollow-cylindrical base body.

The elastic elements, in particular centering elements, are also arranged and designed, in particular in such a number and / or distribution, in particular distributed over the circumference, in particular the outer circumference, of the base body that in the state of the radial compensation element and the connecting bolt arranged on the first component a force polygon of forces acting on the first component through the elastic elements always remains closed and / or centering forces of the elastic elements, in particular the centering elements, always balance each other out. This will center the connecting bolt securely in the nominal position. In addition, there are negative influences on the function of the overall device, i.e. H. on the implementation of the tolerance compensation, avoided.

The elastic elements, in particular centering elements, are each designed, for example, as a tongue, arm, wing, beam, belt, plate, flag or the like. One end of the respective elastic element facing the base body is arranged on the outer circumference of the base body. In particular, this end of the respective elastic element is molded or fastened to the outer circumference of the base body.

The respective elastic element and, in particular, the opposite end of the respective elastic element that points away from the base body extend at least substantially in a circumferential direction of the base body. The respective elastic element is curved in this circumferential direction in such a way that the radial distance from the base body increases in the direction of the pointing end of the respective elastic element. The respective elastic element can additionally have a kink area which is formed transversely to the longitudinal extension of the respective elastic element.

The elastic elements, in particular centering elements, can moreover each be arranged in a spiral shape or in the shape of a spiral section on the base body. They are thus in particular each designed as a spiral spring or as a flexural buckling spring, in particular as a flexural / buckling spring curved in the bending direction and thus in the spring tensioning direction. As a result, particularly good elasticity and thus spring force of the elastic elements and a particularly good centering effect in the nominal position are achieved in a particularly simple manner, whereby in particular arranging the device and the connecting bolt in this nominal position, especially on the first component, is not hindered by the elastic element becomes.

Another embodiment provides that the base body has an inner ring which forms the receiving channel for the connecting bolt. In an alternative embodiment, the base body can additionally have an outer ring, the inner ring and the outer ring being arranged coaxially to one another and being connected to one another by means of the elastic elements.

According to a further embodiment, the inner ring has an inner dimension that is smaller than the outer dimension of the connecting bolt, so that it is pressed into the receiving channel in the inserted state.

A further aspect provides that the inner ring has a plurality of flexible wall sections arranged distributed in the circumferential direction, the inner ring in an initial state of the flexible wall sections having an inner dimension which is smaller than the outer dimension of the connecting bolt. When the connecting bolt is inserted into the receiving channel, the flexible wall sections are widened and tensioned so that the inner ring and the connecting bolt are fixed and secured to one another by form fit or force fit, in particular by being pressed against one another, in particular are clamped together.

In one possible embodiment, the radial compensation element is formed from a plastic material or a spring metal material, in particular from a spring steel sheet or a thin, elastic metal sheet. The radial compensation element made of plastic is in particular an injection-molded part.

With regard to the device for compensating tolerances between the first component and the second component to be connected to this first component by means of the connecting bolt, the radial compensation element described above is provided, which is arranged between the connecting bolt and the first component and coaxially to them.

The solution according to the invention ensures that the device is always in the nominal position during assembly, in particular in every possible installation position of the device, since it is due to the elastic Radial compensation element, in particular both by the form fit or force fit, in particular press fit, of the connecting bolt in the radial compensation element and by the spring force of the elastic elements, is held in the nominal position. This makes assembly much easier. In particular, in unfavorable assembly positions in which no direct view of the device and / or the first component and / or the connecting bolt, such as a screw element, of the device is possible, assembly is made considerably easier by the solution according to the invention, since this is ensured that the device and thus also the connecting bolt are always in the same position. In particular, assembly is also facilitated in those cases in which, for example, the connecting bolt has to be inserted into the device without direct view and / or a tool must be guided without direct view of the connecting bolt, in particular a screw head of the connecting bolt. For example, a complex search for the connecting bolt, in particular its screw head, for example by manual feeling, and a correspondingly complex positioning of the tool on the screw element are avoided.

In addition, the elastic radial compensation element (also referred to as the elastic centering element) is designed in such a way that lateral forces do not negatively affect the tolerance compensation, in particular the function of the device, in particular an unscrewing of a compensation element.

According to one embodiment, the radial compensation element is held between the connecting bolt and the first component by means of a form fit or friction fit, in particular by pressing them against one another or clamping them together. The elastic elements of the radial compensation element can be designed in such a way that they hold the radial compensation element securely between the connecting bolt and the first component, in particular hold it braced or pressed with one another. For example, the elastic elements are designed in such a way that they preload the radial compensation arrangement in the direction of the first component.

The middle-point M. corresponds in particular to a central axis A. of the radial compensation element 1 .

The radial compensation element 1 comprises a base body 2 that has a recording channel 3 having.

Furthermore, the base body 2 a ring shape, of which several elastic elements 4th at an acute angle α protrude radially outwards.

The basic body 2 has an inner ring 1.1 on, its interior I. the recording channel 3 forms.

Furthermore, the inner ring 1.1 a plurality of flexible wall sections distributed in the circumferential direction 1.2 on. The flexible wall sections 1.2 show one in the interior I. directed crease or fold 1.2.1 , for example in the form of a groove. Here is the respective kink or fold 1.2.1 so in the wall section 1.2 of the inner ring 1.1 introduced that a corresponding respective bulge 1.2.2 over the outer circumference of the inner ring 1.1 protrudes. in the Area of the respective bulge 1.2.2 each is an elastic element 4th molded or attached.

The elastic elements 4th , also called centering elements, are in particular symmetrical about the circumference, in particular the outer circumference, of the base body 1.1 arranged distributed. This enables easy centering.

The elastic elements 4th are, for example, each formed as a tongue, arm, wing, beam, belt, plate, flag or the like. On the basic body 1.1 facing end 4.1 of the respective elastic element 4th is on the outer circumference of the base body 1.1 molded or attached.

The respective opposite and thus from the main body 1.1 groundbreaking end 4.2 of the respective elastic element 4th extends at least substantially in a circumferential direction of the base body 1.1 . Here is the respective elastic element 4th formed so curved in this circumferential direction that a radial distance rA of the respective elastic element 4th along its extension from the base body 1.1 towards the groundbreaking end 4.2 increases. The respective elastic element can 4th an additional kink area 4.3 have, which is transverse to the longitudinal extent of the respective elastic element 4th is trained. They are thus in particular each designed as a spiral spring or as a flexural buckling spring, in particular as a flexural / buckling spring curved in the bending direction and thus in the spring tensioning direction. This results in a particularly good elasticity and thus spring force of the elastic elements in a particularly simple manner 4th and achieves a particularly good centering effect in a nominal position.

The elastic elements 4th can also be in a spiral or spiral segment shape on the base body 1.1 be arranged. in particular, arranging the device and the connecting bolt in this nominal position, in particular on the first component, is not hindered by the elastic element.

2 shows the radial compensation element schematically in a perspective representation 1 . The crease or fold 1.2.1 runs transversely to the longitudinal extent of the inner ring 1.1 and extends the entire length of the inner ring 1.1 .

The kink area also extends 4.3 in the elastic element 4th transverse to the longitudinal extent of the elastic element 4th .

3A , 3B show schematically in a perspective representation or in section an embodiment for a radial compensation element 1 with inserted connecting bolt 5 .

3A shows that the connecting bolt 5 in the recording channel 3 of the main body 2 is arranged. Here is the recording channel 3 set up so that the connecting bolt 5 is held in a press fit.

The inner ring 1.1 has for this purpose, for example, an inner dimension that is smaller than the outer dimension of the connecting bolt 5 so that it is inserted in the receiving channel 3 is pressed into this.

For easy assembly of the connecting bolt 5 in the inner ring 1.1 and thus the recording channel 3 inside, encompasses the inner ring 1.1 the plurality of flexible wall sections distributed in the circumferential direction 1.2 . The inner ring 1.1 in an initial state of the flexible wall sections 1.2 , in which they are relaxed, an inner dimension that is smaller than the outer dimension of the connecting bolt 5 . When inserting the flexible wall sections 1.2 widened and tensioned to the connecting bolt 5 to be introduced and received in such a way that the connecting bolt 5 in a press fit in the receiving channel 3 is held.

The connecting bolt 5 is designed as a screw, for example, which has a screw head 5.1 , a shaft 5.2 with a thread 5.3 , in particular an external thread, and a narrowing shaft end 5.4 as, for example, an insertion aid or tip. The screw head 5.1 has a recess 5.5 on which a screwdriver to turn the connecting bolt 5 is recordable. In addition, the connecting bolt 5 a flange 5.6 on. The flange 5.6 is designed as a mounting or contact flange.

The respective elastic element 4th indicates the kink area 4.3 on, the transverse to the longitudinal extension of the respective elastic element 4th is trained. That the basic body 2 facing end 4.1 of the respective elastic element 4th is in the area of one of the flexible wall sections 1.2 molded or attached.

3B shows the radial compensation element 1 when installed in a device V to compensate for tolerances, especially a gap S. , in particular a height gap, between a first component 6th and one by means of the connecting bolt 5 with this first component 6th second component to be connected 7th .

With the first component 6th it can be, for example, a bearing bracket for an outside door handle of a motor vehicle. The second Component 7th is for example a support structure, in particular a door panel of the motor vehicle.

The first component 6th has at least one hollow cylindrical section 6.1 on, in which the radial compensation element 1 is arranged. The first component 6th is the second component 7th for example on a flat floor section 6.2 arranged. To connect the first component 6th with the second component 7th is the connecting bolt 5 into the recording channel 3 of the radial compensation element 1 introduced and through corresponding through openings 6.3 , 7.1 in the first component 6th or in the second component 7th guided. The connecting bolt is thereby 5 at least in the second component 7th screwed.

To do this, the connecting bolts point 5 a corresponding thread 5.3 in the form of an external thread and the through opening 7.1 corresponding thread sections 7.2 with corresponding slopes. The through openings 6.3 , 7.1 as well as the recording channel 3 of the radial compensation element 1 each define a central axial passage for the connecting bolt 5 , especially a connecting screw. The connecting bolt 5 points at its shaft 5.2 the thread in sections 5.3 on.

On the bottom, on that of the first component 6th remote side of the second component 7th can be a mother element 8th be provided in which the connecting bolt 5 engages, in particular engages screwing. To this end, the nut element 8th an associated thread 8.1 on.

The connecting bolt 5 points the flange 5.6 on which in the assembled state of the device V to the inward-facing bottom section 6.2 is applied. Between the screw head 5.1 and that of the screw head 5.1 facing surface side of the flange 5.6 is the shaft 5.2 designed without threads. This allows the connecting bolt 5 in the recording channel 3 of the radial compensation element 1 be held, in particular included in a press fit or tension fit. Between the end of the shaft 5.4 facing surface side of the flange 5.6 and the shaft end 5.4 is the shaft 5.2 at least in areas or sections with the thread 5.3 Mistake. This allows the connecting bolt 5 for example in the through opening 7.1 of the second component 7th and the mother 8th be screwed in.

For centering the connecting bolt 5 in the hollow cylindrical section 6.1 which is often not visible is the radial compensation element 1 provided to compensate for radial tolerances and the connecting bolt 5 in the hollow cylindrical section 6.1 to center. The radial compensation element is used for this 1 between the connecting bolt 5 and the first component 6th in its hollow cylindrical section 6.1 arranged. The radial compensation element 1 is coaxial with the first component 6th and to the connecting bolt 5 arranged.

Here are the radial compensation elements 1 , the connecting bolt held in this by positive or frictional engagement, in particular in a press connection 5 and the first component 6th held together by positive or frictional engagement, in particular by pressing or bracing against one another. To do this are the elastic elements 4th of the radial compensation element 1 designed in such a way that they have the radial compensation element 1 between the connecting bolt 5 and the first component 6th keep tense. In particular, the elastic elements 4th designed in such a way that they have the radial compensation element 1 towards the first component 6th preload.

The radial compensation element 1 includes, for example, four symmetrically around the circumference of the base body 2 distributed, elastic elements 4th , in the form of elastic tongues or spring elements.

For assembling the device V become the first component 6th and the second component 7th screwed together. For example, the first component 6th including the radial compensation element 1 , that is, with the non-positive, in particular frictional in the first component 6th arranged radial compensation element 1 , on the second component 7th arranged. Then the connecting bolt 5 in the radial compensation element 1 inserted and into the through openings 6.3 and 7.1 through into the second component 7th and / or the nut element 8th screwed in. By screwing the components together 6th and 7th together the gap becomes S. closed.

When inserting and possibly screwing in the connecting bolt 5 into the through openings 6.3 , 7.1 and the mother element 8th there is a relative movement between the elastic elements 4th of the radial compensation element 1 and the first component 6th , which a tension of the elastic elements 4th in the first component 6th causes. This results in radial tolerances between the connecting bolt 5 and the first component 6th balanced and a corresponding game avoided, whereby the connecting bolt 5 is kept free of play.

4th shows a schematic plan view of an alternative embodiment for a radial compensation element 10 . For a robust and sufficiently strong design of the radial compensation element 10 includes this in addition to that in the 1 to 3B embodiment shown an outer ring 1.3 . The basic body 2 with the inner ring 1.1 and the elastic elements 4th is analogous to the embodiment according to 1 to 3B executed. To avoid repetition, refer to the description of these 1 to 3B referenced.

The respective from the base body 2 groundbreaking end 4.2 of each elastic element 4th is on an inside of the outer ring 1.3 molded or attached to this.

In other words: the alternative radial compensation element 10 has a double ring structure, the elastic elements 4th the inner ring in the form of flexible bars 1.1 with the outer ring 1.3 connect. The inner ring 1.1 and the outer ring 1.3 are arranged coaxially to each other and by means of the elastic elements 4th connected with each other.

5 shows the alternative radial compensation element schematically in a perspective illustration 10 .

6th and 7th show schematically in perspective the alternative radial compensation element 10 with connecting bolts inserted in a form-fit or force-fit connection, for example in a press connection 5 .

8th to 10 shows schematically an alternative device in a sectional view or a partial sectional view V ' to compensate for tolerances with the alternative radial compensation element 10 for centering the connecting bolt 5 in the alternative device V ' and thus compensation of radial tolerances and an axial compensation element 11 to compensate for axial tolerances between the two components 6th and 7th . Instead of the alternative radial compensation element 10 can also use the simple radial compensation element 1 in the alternative device V ' be used.

The axial compensation element 11 is for example in the first component 6th screwed in. Alternatively, between the axial compensation element 11 and the first component 6th a base element (not shown) can be arranged in which the axial compensation element 11 is screwed in, the base element in turn with the first component 6th can be clipped, pressed, glued or welded or can be formed in one piece with this.

The first component 6th or the base element (not shown) each have an internal thread in an analogous manner 6.5 on. The internal thread 6.5 can be designed continuously or divided into sections. The axial compensation element 11 is in the first component 6th or the basic element can be screwed in. To this end, the axial compensation element 11 a corresponding external thread 11.1 on.

The axial compensation element 11 is designed as a hollow cylinder and has a hollow cylindrical section 11.2 and a bottom section 11.3 on.

The bottom section 11.3 defines a central axial passage 11.4 for the connecting bolt 5 as well as one at the passage 11.4 adjoining attack surface 11.5 for the head 5.1 of the connecting bolt 5 .

It is basically possible to use a diameter of the passage 11.4 to be chosen to be minimally larger than an outer diameter of the shaft 5.2 of the connecting bolt 5 so that the head 5.1 directly with the attack surface 11.5 can get in touch. The connecting bolt 5 points the flange 5.6 on, the one with the attack surface 11.5 comes into contact. In the exemplary embodiment, between the flange 5.6 and the attack surface 11.5 a washer 9 , for example a disc or a T-shaped element, be arranged.

In order to be able to better compensate for further radial tolerances, the diameter of the passage 11.4 but larger than an outer diameter of the flange 5.6 be chosen so that the washer 9 between the flange 5.6 and the bottom section 11.3 of the axial compensation element 11 is arranged to prevent the flange 5.6 in the passage 11.4 entry. In this case the flange lies 5.6 in the final assembly state ( 9 and 10 ) so only indirectly, namely via the washer element 9 , at the attack surface 11.5 of the axial compensation element 11 at.

The axial compensation element 11 can consist of two segments, here in the form of hollow cylinder halves 11a , 11b , be formed, which are elastically connected to one another. For example, the two hollow cylinder halves 11a , 11b connected to one another by pairs of axially spaced apart spring elements (not shown) or elastic webs. The spring elements or webs can be angled, in particular several times, for example twice angled, or alternatively they can be bent or folded accordingly. The two hollow cylinder halves can also 11a , 11b be clipped together, the connection being designed to be correspondingly elastic and, in particular, movable in the axial direction.

In an initial or rest state of the axial compensation element 11 are the hollow cylinder halves 11a , 11b so axially offset to the second component 7th arranged that an axial offset VS or gap between the compensation element 11 and the second component 7th given is ( 8th ).

On the outside of the axial compensation element 11 is the external thread in the circumferential direction 11.1 educated. The external thread 11.1 can be designed continuously or alternatively have several thread sections (not shown). Each hollow cylinder half has 11a , 11b a corresponding external thread 11.1 on. Here is the pitch of the respective external thread 11.1 of the axial compensation element 11 to the pitch of the internal thread 6.5 of the first component 6th or of the base element, i.e. also the external thread 11.1 forms a coarse thread, so that the thread engagement from the first component 6th and axial compensation element 11 is not self-locking.

Should be the first component 6th with the second component 7th are screwed, so the first component 6th with the axial compensation element screwed into it 11 on the second component 7th arranged. Next is the radial compensation element 10 or the connecting bolt 5 including the radial compensation element 10 and the washer 9 in the axial compensation element 11 introduced and through the passage 11.4 of the axial compensation element 11 as well as through a bore or through opening 7.1 of the second component 7th through into the nut element 8th screwed in.

As soon as the head 5.1 of the connecting bolt 5 over the washer 9 with the bottom section 11.3 of the axial compensation element 11 comes into contact and an axial force on the axial compensation element 11 exercises, this occurs from the first component 6th out until it is on the second component 7th is present ( 9 and 10 ). It goes without saying that the axial compensation element 11 on the second component 7th comes to rest and with a further tightening of the connecting bolt 5 finally both halves of the base 11.3a , 11.3b between the washer 9 and the second component 7th are clamped and thus the offset VS is balanced.

The axial displacement of the axial compensation element 11 causes tension in the external thread 11.1 of the axial compensation element 11 in the internal thread 6.5 of the first component 6th or the primitive (not shown). This results in tolerances between the threads 11.1 , 6.5 balanced and play in the thread engagement between the first component 6th and the axial compensation element 11 eliminated.

As a result, the device provides V with radial compensation element 1 and device V ' with radial compensation element 10 (Functioning analogous to the radial compensation element 1 ) and axial compensation element 11 in this way, despite possible structural tolerances, for a play-free and reliable screw connection of the first component 6th on the second component 7th .

9 and 10 show the device V ' in the clamped state, in which the flange 5.6 of the radial compensation element 10 on the washer 9 and this on the bottom section 11.3 of the axial compensation element 11 and this in turn on the second component 7th abut so that both axial tolerances between the two components 6th and 7th as well as radial tolerances between connecting bolts 5 and first component 6th are balanced.
