Connecting element between two spaced-apart components with tolerance compensation function and an installation method for it

Description

1. Field of the invention

[0001] The present invention relates to a connecting element for two spaced-apart components with a tolerance compensation function. Furthermore, the present invention relates to a method for connecting a first and a second component at a distance from each other using the aforementioned connecting element. 2. Background of the invention

[0002] Various connecting elements or systems are known in the prior art for joining two components at a fixed distance from each other. For example, US 2017 / 0051780 A1 discloses a first component in whose opening a sleeve-shaped clip is arranged. A holder of a second component attaches a pin whose shape is adapted to create a positive-locking connection with the aforementioned clip. A connection between these two components is established by inserting the clip and pin into each other. However, this connecting system has the disadvantage that only an axial connection between the pin and the clip can be established, while tolerances occurring in the axial and lateral directions cannot be compensated for by any correction mechanism.

[0003] DE 42 24 575 A1 describes a connection arrangement with automatic tolerance compensation. For this purpose, the connection arrangement is first attached to a first component.

[0004] The second component, which is spaced apart from the first, is connected to the first component via a threaded bolt and the connecting assembly. As the threaded bolt is screwed into the connecting assembly, an automatic tolerance compensation mechanism is used, which compensates for the gap between the first and second components. Once the tolerance compensation mechanism bridges the gap between the two components, the threaded bolt is screwed into a fastening receiving thread. This connecting assembly is complex in its design. First, the automatic tolerance compensation must be achieved by coordinating various threaded connections within the assembly. Furthermore, not every connection situation allows the use of a threaded bolt, which can only be reliably screwed into the connecting assembly after a specific processing time.

[0005] DE 10 2007 002 699 A1 describes a fastening device based on the use of two telescopically connected sleeves. These sleeves are connected via an internal and an external thread to bridge a gap between a first and a second component. A connecting threaded bolt runs inside the inner sleeve to screw the first and second components together. Accordingly, the telescoping sleeves can compensate for axial tolerances. Since the connecting threaded bolt has a smaller cross-section than the inner diameter of the inner sleeve, radial tolerances are compensated for by a relative offset between the threaded bolt and the surrounding sleeve.

[0006] US 2018 / 0328390 A1 utilizes a central bolt with two opposing threaded ends and an intermediate spacer to fasten two components at a certain distance from each other. Each threaded end requires a corresponding mating thread to create a connection on both sides of the threaded bolt. This involves considerable design and subsequent processing effort. To reduce the connection effort at at least one threaded end of the central bolt, a connecting sleeve is screwed onto one threaded end of the connecting bolt. This connecting sleeve can be locked into a multi-part locking mechanism on the second component. A locking clip is held in a retaining cage on the second component, into which the sleeve, screwed onto the threaded bolt, can be engaged.To compensate for axial tolerances between the two components, the threaded bolt can also be adjusted within the locking threaded sleeve. For this purpose, the threaded sleeve is rotatably mounted in its locking position. Due to the large number of parts required to create the connection between the two spaced-apart components, it becomes clear that this connection arrangement requires not only significant manufacturing effort but also a correspondingly high installation effort.

[0007] DE 10 2017 124 470 A1 relates to a tolerance compensation arrangement for fastening a first component to a second component with automatic compensation of tolerances in the distance between the first component and the second component. The tolerance compensation arrangement comprises a base element having a first metal element with a first internal thread and a second metal element with a second internal thread, spaced apart from each other along a longitudinal axis of the base element, and an adjusting unit comprising a threaded sleeve made of metal with an external thread and a follower unit arranged at least partially in the threaded sleeve, wherein the external thread forms a first thread pairing of a first thread direction with the first internal thread of the first metal element of the base element.A fastening screw can be inserted through an opening in the base unit and the adjustment unit and screwed into the second internal thread of the second metal element of the base element via a second thread pairing in the opposite direction to the first. Furthermore, the fastening screw can be connected to the adjustment unit via the follower unit by a detachable follower connection, so that when the fastening screw is tightened, the adjustment unit rotates along with it and is thus moved into contact with the first component.

[0008] In view of the state of the art, the object of the present invention is therefore to provide an alternative connecting element for two spaced-apart components with a tolerance compensation function. 3. Summary of the invention

[0009] The above problem is solved by a connecting element according to independent claim 1, a connection of two components with the connecting element according to claim 11, and by a connecting method of two components according to claim 12.

[0010] Advantageous embodiments and further developments are described below, illustrated in the drawings, and set forth in the attached claims. The present invention discloses a connecting element for two spaced-apart components with a tolerance compensation function. The connecting element has the following features: a hollow screw with an external thread, with which a threaded connection to a first component can be established, which is adjustable in the longitudinal direction of the hollow screw via at least one drive element; a nut element, which is received in a receiving space of the hollow screw and which comprises a radially inner functional surface, such that a positive-locking and / or force-locking connection can be established with a first connecting end of a connecting bolt, wherein the connecting bolt has a second connecting end with which a connection to a second component can be established.

[0011] The present invention describes a connecting element that joins two components at a defined distance from each other. Within this connection, or fastening of the two components to one another, the connecting element allows for the compensation of various tolerances to achieve an optimal connection. These tolerances include axial tolerances, which can be adjusted by turning the hollow screw. The hollow screw sits in a preferably self-tapping thread of the first component. By turning the hollow screw, the connecting element is moved in its axial direction—that is, along its longitudinal axis—in one direction or the other. Furthermore, the inner cavity of the hollow screw, as well as the combination of nut element and connecting bolt arranged within it, allows for the compensation of lateral tolerances perpendicular to the longitudinal axis of the connecting bolt.The combination of connecting bolt and nut element preferably creates a friction-fit connection with the hollow screw during the connection process. The position of this friction-fit connection can be adjusted within the available space of the hollow screw, allowing the connecting element to compensate for lateral tolerances in a plane perpendicular to the longitudinal axis of the connecting bolt. It is understood that the terms "friction-fit" and "friction-fit" are used synonymously.

[0012] The connecting bolt has a first functional connection end which forms a positive and / or force-fit connection with the nut element. Depending on the connection forces to be achieved within the connecting element and the available cycle time for creating the connection, the connection between the nut element and the connecting bolt can be implemented as a quick-release fastener, a snap-fit ​​fastener, or a threaded connection.

[0013] Accordingly, the nut element has an internal thread as its functional surface and the connecting bolt an external thread, or the nut element has a radially inwardly directed guide ridge or cam and the connecting bolt has a curved or straight guide groove or ramp. Preferably, interlocking detent ridges and detent grooves are provided on the nut element and the connecting bolt, which are positioned at successive axial positions.

[0014] With regard to the second connecting end of the connecting bolt, a force-fit and / or form-fit connection with the second component can be established. For this purpose, the second component provides an opening into which the second connecting end of the connecting bolt engages and is secured. According to a preferred embodiment of the present invention, the second connecting end is designed as a quick-release fastener, such as a bayonet fitting. This engages in a corresponding keyhole in the second component. According to a further preferred embodiment, the second connecting end of the connecting bolt has a threaded section that connects to a corresponding nut element.

[0015] According to a preferred embodiment of the present invention, a first opening of the hollow screw has an opening diameter that is larger than a bolt diameter of the connecting bolt projecting into the hollow screw, so that the connecting bolt can be laterally displaced within the first opening of the hollow screw to compensate for tolerances.

[0016] As mentioned above, the design of the hollow cylindrical or sleeve-shaped banjo bolt allows for lateral offset of the connecting bolt with respect to its longitudinal axis within the banjo bolt. This compensates for lateral or radial tolerances with respect to the longitudinal axis of both the connecting bolt and the banjo bolt. Since the connecting bolt, preferably in combination with the nut, is fastened at a specific radial position within the banjo bolt, the necessary tolerances in the alignment of the banjo bolt and connecting bolt are thus compensated for, ensuring optimal connection quality.

[0017] According to a further preferred embodiment of the present invention, the hollow screw has a radial collar projecting into the first opening, to which the nut element and the connecting bolt can be attached by a common connection in order to fix a radial position of the connecting bolt within the first opening.

[0018] According to a preferred embodiment of the present invention, the first component has a receiving opening for screwing in the hollow screw. The second component is also equipped with a receiving opening or other suitable design for establishing a connection with the second end of the connecting bolt. In order to effectively connect these two openings, or the first and second components, alignment tolerances between the first and second components are compensated not by moving the components themselves, but by moving or offsetting the connecting bolt within the hollow screw.

[0019] According to a preferred embodiment of the present invention, the connecting bolt, after assuming its suitable radial position within the hollow screw, is firmly connected to the nut element. This achieves a preferred clamping or, more generally, a force-fit connection between the nut element and the connecting bolt with a radial collar of the hollow screw projecting radially inward into the hollow screw. In this way, the connection between the nut element and the functional bolt is firmly arranged within the hollow screw. The design of the preferred radial collar allows the connecting bolt to be arranged not necessarily coaxially with a longitudinal axis of the hollow screw.Rather, the use of the radial collar and a force-fit connection between the connecting bolt and the nut element on this radial collar preferably results in a parallel alignment of the connecting bolt to the longitudinal axis of the hollow screw, so that they preferably lie next to each other in a common imaginary plane.

[0020] Preferably, the connecting bolt between the first and second connection ends has a radially outward projecting connecting flange that supports a force-fit connection with the hollow screw.

[0021] According to a preferred embodiment of the present invention, a radially outwardly projecting connecting flange is arranged on a connecting bolt. A preferred fixed connection between the connecting bolt and the nut element ensures that the radial collar of the hollow screw is held force-fit between the connecting flange and the nut element. This guarantees that the selected radial position of the connecting bolt within the hollow screw is fixed.

[0022] According to the invention, the connecting flange preferably has webs or ribs facing the hollow screw, which provide positive locking support for a connection between the hollow screw and the connecting bolt.

[0023] According to a further preferred embodiment of the present invention, radially extending webs are provided on the connecting flange on one side facing the hollow screw. These webs project from the plane of the connecting flange. This results in the webs projecting from the connecting flange being pressed into, preferably, the radial collar of the hollow screw or into a further part of the hollow screw at its axial end, within the framework of a preferred force-fit connection with the nut element. A positive-locking connection preferably resulting from this forms, according to various preferred embodiments, a labyrinth seal or a rotational restraint of the connecting bolt relative to the hollow screw. These two functional alternative embodiments of the connecting flange support an improved quality of the connection between the first and the second component via the connecting element preferred according to the invention.

[0024] In a further preferred embodiment of the present invention, a hat-like sealing element is provided on the connecting flange, which projects towards the second connection end in order to seal a connection to a second component.

[0025] According to a further preferred embodiment of the present invention, a sealing element is provided on the connecting flange. This sealing element is oriented towards the second component such that when the second connecting end of the connecting bolt is connected to the second component, a sealing contact is established between the sealing element and the second component. This contact ensures that the sealing element preferably seals the connection to the connecting element around a mounting opening on the second component into which the connecting bolt engages. This preferably ensures that moisture, dust, or similar contaminants cannot penetrate through the opening in the second component to reach the connecting element. The sealing element shields the opening in the second component in such a way that such contaminants collect on the sealing element.

[0026] To achieve its sealing function, the sealing element, according to a preferred embodiment, is hat- or cup-shaped with an opening facing the second component, or in other words, away from the hollow screw. In this way, the sealing element opens towards the second connecting end of the connecting bolt. The preferred hat- or cup-shaped structure of the sealing element results in a wall of the sealing element being oriented away from the hollow screw, i.e., towards the second connecting end of the connecting bolt, similar to the rim of a hat or the circumferential wall of a pot. Since a flexible material, such as an elastomer, is used for the sealing element according to a preferred embodiment, this edge conforms to the second component during connection, thus achieving the sealing function.

[0027] The connecting bolt has a drive element adjacent to the first connecting end.

[0028] To establish a preferred connection between the second end of the connecting bolt and the second component, a drive element is required to transmit a preferred torque to the connecting bolt. This drive element is located adjacent to the first end of the connecting bolt. This has the advantage that the second end of the connecting bolt, which is opposite the hollow screw, is fully functional for establishing the connection with the second component.

[0029] Furthermore, this design of connecting element allows the connection between the first and second components to be established even with access from only one side of the connection point. Therefore, this connecting element can be used even at hard-to-reach connection points between two components, while ensuring the required distance between them.

[0030] According to a further preferred embodiment of the present invention, the radially inner functional surface of the nut element and the first connecting end of the connecting bolt form a quick-release fastener, in particular a quarter-turn quick-release fastener.

[0031] To minimize the cycle time required to connect the two components, a quick-release connection is provided between the nut element and the first end of the connecting bolt. This creates a force-fit and / or form-fit connection to the hollow screw with minimal effort, thus compensating for any tolerances that may occur when joining the two components with the connecting element.

[0032] According to a further preferred embodiment of the present invention, the first connecting end of the connecting bolt has an external thread and the nut element has a corresponding internal thread for producing a threaded connection.

[0033] According to a further preferred embodiment of the present invention, the connection between the nut element and the first connecting end of the connecting bolt is provided as a threaded connection. This means that the nut element has an internal thread and the first connecting end of the connecting bolt has a corresponding external thread. In comparison to a quick-release connection, such a threaded connection achieves higher connection forces, which may be required depending on the two components being joined. Compared to a quick-release connection between the nut element and the first connecting end, a threaded connection requires more time to establish than a snap-fit ​​or bayonet connection.

[0034] Preferably, the second connecting end of the connecting bolt forms a quick-release fastener with a connecting opening in a second component, in particular a quarter-turn quick-release fastener or a bayonet fastener.

[0035] According to a further preferred embodiment of the present invention, the second connecting end of the connecting bolt is designed as a quick-release fastener. Accordingly, this feature of the second connecting end of the connecting bolt interacts with an opening in the second component in such a way that, for example, a load-bearing, force-fit and / or form-fit connection with the second component can be established with just a quarter turn. This functional design further reduces the cycle time for establishing the connection between the two components. Naturally, it is also preferred to adapt this connection for higher connection forces by, for example, creating a threaded connection between the second connecting end of the connecting bolt and the second component at the component opening.For example, the second component may have an internal thread at the component opening, or a weld nut adjacent to the component opening, or a blind rivet nut that has previously been inserted into the component opening of the second component.

[0036] According to another preferred embodiment of the present invention, the hollow screw has a first and a second drive means which are arranged adjacent to the opposite axial ends, in particular an outer drive means and an inner drive means.

[0037] The hollow screw is screwed into an opening in the first component. This pre-positioning of the hollow screw or the connecting element can be achieved, for example, in a preparation process for the first component. Accordingly, these preparation processes are often not characterized by a lack of space requirements, so that preferably the hollow screw is screwed into the corresponding opening of the first component via an external drive feature. A known embodiment of an external drive feature is a polygon, such as a hexagonal structure.

[0038] To ensure optimal axial tolerance compensation between the first and second components within a connection between them, the hollow screw preferably has a second drive feature. This second drive feature comes into play when, for example, the outer first drive feature, the aforementioned polygon, is difficult to access or obscured by the connection. Therefore, according to the invention, it is preferred to provide a drive feature within the hollow screw into which a suitable tool can engage in a form-fitting manner. According to a preferred embodiment of the present invention, the second drive feature is provided at the axial end of the hollow screw that faces away from the radial collar.Thus, this second drive feature also preferentially supports the one-sided accessibility mentioned above when establishing a connection between a first and a second component.

[0039] The present invention also discloses a connection between a first and a second component spaced apart from each other using the connecting element described above.

[0040] Using the connecting element preferred according to the invention, a vehicle light is preferably connected to a vehicle chassis, a handle assembly to the vehicle body, or a seat assembly to a vehicle frame or the like. Basically, two components are connected to each other, which must be arranged and fastened at a specific distance from each other.

[0041] Furthermore, the present invention describes a method for connecting a first and a second component at a distance from each other using the connecting element according to the embodiments described above. The connecting method comprises the following steps: screwing the hollow screw of the connecting element into a first fastening opening on the first component, fastening the second connecting end of the connecting bolt in a second fastening opening of the second component, whereby radial tolerances are compensated for in an axial alignment of the hollow screw and the connecting bolt, connecting the nut element and the first connecting end of the connecting bolt, so that the connecting bolt is fastened to the hollow screw.

[0042] The present invention further discloses a method for connecting two components using the connecting element. In this method, the hollow screw is first screwed into a prepared opening in the first component. Preferably, the hollow screw has a self-tapping and / or self-sewing external thread for this purpose, which creates a corresponding nut thread in the opening of the first component. Once the hollow screw, and thus the entire connecting element, has been positioned and secured in the first component, the connecting element is axially positioned within the first component by further rotating the hollow screw. It is also preferred to carry out this axial positioning at a later stage, preferably after the connection between the first and second components has been established.

[0043] The first component is then positioned relative to the second component and a preferably provided opening in the second component to establish the connection between them via the connecting element. For this purpose, the connecting bolt is first secured in the second component using the aforementioned drive feature of the connecting bolt. Subsequently, any lateral or radial tolerances with respect to the longitudinal axis of the connecting bolt are compensated for by positioning the connecting bolt, in combination with the nut element, appropriately within the hollow screw. Once this suitable radial position of the connecting bolt and nut element has been determined, the connection between the connecting bolt and nut element is established by force-fit and / or positive locking. Based on this connection, the connecting bolt is fixed in its desired radial position on the preferred radial collar of the hollow screw.

[0044] According to a preferred embodiment of the joining method, a further step is provided: turning the hollow screw in the first component to adjust the axial position of the connecting element.

[0045] Preferably, the next step involves: loosening the nut element inside the hollow screw, changing the radial position of the connecting bolt relative to the hollow screw, and then attaching the nut element to the connecting bolt.

[0046] During the installation or connection process of the first and second components, it is also preferred to compensate for certain tolerances. The preferred second drive feature allows the hollow screw to be rotated in such a way that axial tolerances in the distance between the first and second components can be adjusted. Furthermore, if there are radial deviations in the alignment of the connecting element relative to the opening of the second component, these radial tolerances can be adjusted or compensated for by repositioning the connecting bolt.

[0047] For this purpose, it is preferred to rotate the nut element using a suitable tool so that the connection between the connecting bolt and the nut element is released. After release, the connecting bolt can be readjusted to a suitable position for the connection, allowing the connection between the nut element and the connecting bolt to be subsequently re-established. Accordingly, the connecting element allows for the correction of tolerances occurring in the axial and radial directions, both during the initial connection between the first component and subsequently. 4.

Detailed description of preferred embodiments

[0049] The present invention describes a connecting element 1 with which two components A, B are connected to each other (see Figure 1 , 12 , 20, 21Within the formed connection, the connecting element 1 maintains a defined distance between the two components A and B. Furthermore, due to its design, the connecting element 1 is able to compensate for existing tolerances in the alignment of the components A and B to be joined, in order to improve the quality, reliability, and load-bearing capacity of the formed connection. The connecting element 1, 101; 201; 301 enables axial tolerance compensation along a longitudinal axis L of the hollow screw 10; 110; 210; 310 and lateral tolerance compensation perpendicular to the longitudinal axis L of the hollow screw 10; 110; 210; 310.

[0050] A first preferred embodiment of the connecting element 1 is shown in a perspective sectional view in Figure 1 shown. It consists of a sleeve-like hollow screw 10 with an external thread 12 and an inner cavity 14.

[0051] The hollow screw 10 is screwed into an opening O of the first component A. To simplify the fastening of the hollow screw 10, and thus of the connecting element 1, in the first component A, the thread 12 is configured as a self-tapping and / or self-tapping thread. It is also preferred to use other thread configurations that provide suitable fastening in the opening O of the first component A.

[0052] Preferably, the self-tapping and / or self-tapping thread creates a rotation-resistant effect that holds the hollow screw 10 securely in the opening O. Even if the hollow screw 10 is repositioned axially after installation by further rotation, the self-tapping and / or self-tapping thread continues to ensure a reliable hold of the hollow screw 10 in the opening O of the first component A.

[0053] The hollow screw 10 has a first opening 18 at a first axial end 16, which is large enough to insert a nut element 40 into the cavity 14 of the hollow screw 10. The nut element 40, which is described in more detail below, is preferably received in the cavity 14 in an approximately coaxial orientation to the longitudinal axis L of the hollow screw 10.

[0054] A second opening 22 is provided at a second axial end 20 of the hollow screw 10. The second opening 22 has a smaller diameter than the first opening 18. The second opening 22 is reduced in size by a radially inwardly projecting radial collar 26, against which the nut element 40 is supported by a connecting bolt 60 (see below).

[0055] The hollow screw 10 is in a preferred embodiment in the Figures 3 and 4A more detailed perspective view is shown. Preferably, an external drive element 24, in particular a polygon or hexagon, is provided adjacent to or near the second opening 22 of the hollow screw 10. The drive element 24 serves to transmit a torque to the hollow screw 10 in order to screw it into the opening O of the first component A and thus fasten it.

[0056] The radial collar 26 preferably has a contact surface 28 for the connecting bolt 60 on an axial outer surface. Preferably, the contact surface 28 is annular in shape. It is also preferred that this contact surface 28 be angular or consist of several surface segments arranged regularly around the second opening 22 of the hollow screw 10. The contact surface 28 also preferably forms a contact surface with the connecting bolt 60 when the latter is supported or clamped to the radial collar 26 via the contact surface 28 by means of a connecting flange 62 in a force-fit connection with the nut element 40.

[0057] Adjacent to the opening 22 at the first axial end 16, a circumferential embossed rib 30 is preferably provided. The embossed rib 30 also preferably projects beyond the contact surface 28 in the axial direction. It has a round or angular circumferential shape.

[0058] The axially projecting embossed rib 30 is preferably pressed or embossed into a connecting flange 62 of the connecting bolt 60 in the friction-fit connection between the nut element 40 and the connecting bolt 60. In addition to the friction-fit connection between the nut element 40 and the connecting bolt 60, this forms a positive-locking connection between the hollow screw 10 and the connecting flange 62 of the connecting bolt 60. The positive-locking connection serves to support and ensure the radial position of the nut element 40 and the connecting bolt 60 with respect to the hollow screw 10. Furthermore, the positive-locking connection preferably seals the connecting element 1 against externally penetrating media, for example by forming a labyrinth seal.

[0059] According to a further preferred embodiment of the present invention, the hollow screw 10 has a second drive element 32 adjacent to the first axial end 16. According to various preferred embodiments, the drive element 32 is provided on the axial end face of the first axial end 16, or on the radial outer side of the hollow screw 10, or on the radial inner side of the cavity 14. Due to its arrangement, the drive element 32 allows access for a tool even when the connecting element 1 and two components are installed. A torque can be transmitted to the hollow screw 10 by means of a preferred positive locking mechanism between the tool and the drive element 32 in order to change the axial position of the hollow screw 10 in the opening O of the first component A.

[0060] According to a first preferred embodiment of the present invention, the connecting bolt 60 is located in the Figures 5 and 6shown in more detail. The connecting bolt 60 is adapted to be used with the preferred embodiment of the nut element 40 according to the Figures 7 and 8 preferably to enter into a detachable connection.

[0061] The preferred connecting bolt 60 has a first axial connecting end 64 to form a positive-locking and / or force-locking connection with the nut element 40.

[0062] Preferably, the interacting connecting surfaces of the nut element 40 and the first connecting end 64 of the connecting bolt 60 are designed such that the connection between the connecting bolt 60 and the nut element 40 can be released without damage.

[0063] The connecting surfaces of the first connecting end 64 of the connecting bolt 60 are arranged along a shaft 66 of the connecting bolt 60. In the connecting element 1, the shaft 66 is arranged in the cavity 14 of the hollow screw 10 and passes through the nut element 40, which is also arranged there.

[0064] The first connecting end 64 is preferably limited in the axial direction by the radially extending connecting flange 62, which is arranged outside the cavity 14 of the hollow screw 10. The first connecting end 64 also extends into a drive element 68 to rotate the connecting bolt 60. Preferably, the drive element 68 is designed as a polygon, a slot, a ridge, a cross, or an Allen key.

[0065] Adjacent to the connecting flange 62, a second axial connecting end 70 is provided on the side of the connecting bolt 60 facing away from the shaft. The second axial connecting end 70 is adapted to create a connection, preferably a detachable connection, with the second component B.

[0066] According to a preferred embodiment of the second connecting end 70, it forms a quick-release fastener with an opening O in the second component B. A bayonet connection is preferred according to the invention, such that the second connecting end 70 fits into a keyhole S (see figure). Figure 24 ) engages and locks there via a quarter turn. It is also preferred to design the second connecting end 70 as a threaded bolt or threaded shaft in order to fasten it in the opening O of the second component B using a nut.

[0067] The second connection end 70 points in the Figure 6In the preferred embodiment shown, a central centering projection 72 with opposing and radially projecting locking wings 74 is provided. The centering projection 72 comprises two opposing centering planes 73 that taper radially inwards towards the free end of the centering projection 72. These centering planes 73 facilitate the insertion of the second connection end 70 into the opening O of the second component B.

[0068] Preferably, an orientation rib 76 is arranged on the centering projection 72, which indicates the rotation angle setting of the connecting bolt 60 relative to the keyhole S. A similar marking is preferably also found at the axial end of the first connection end 64.

[0069] When inserting and locking the second connection end 70 in the keyhole S of the second component B, the centering projection 72 is inserted through a central opening and the radially projecting locking wings 74 through radial recesses of the keyhole S (see Figure 25 ). The connecting bolt 60 is then preferably rotated about its longitudinal axis L via the drive feature 68 until, after a rotation of preferably 90°, at least one locking lug 78, preferably two locking lugs arranged opposite each other, engage in the radial recesses of the keyhole S (see Figure 26 ).

[0070] To facilitate the preferential release of the latched locking lugs 78, the locking lug 78 is provided on one side with a release ramp 79. The locking lug 78 preferably extends along a partial arc around the longitudinal axis L of the connecting bolt 60. Accordingly, the release ramp 79 is located on one (see Figure 6 ) or at both ends of the locking lug 78. The connecting bolt 60 is rotated such that the release ramp 79 engages a radial edge of a radial recess of the keyhole S. Due to the rotation, the release ramp 79 pushes the locking lug 78 axially out of the radial recess, thereby releasing it and allowing further rotation of the connecting bolt 60.

[0071] Pre-installed in the hollow screw 10, the connecting bolt 60 passes through the second opening 22 of the hollow screw 10 and is held in the cavity 14 by the nut element 40.

[0072] According to a first preferred embodiment of the connecting element 1, the connecting bolt 60 is designed according to the Figures 5 and 6 detachably connected to the nut element 40, which is located in the Figures 7 and 8as shown in preferred embodiments. The nut element 40 is sleeve-like, with a circumferential wall 42, an interior space 44 enclosed by the wall 42, an inlet opening 46 and an outlet opening 48.

[0073] According to a preferred embodiment of the present invention, the circumferential wall 42 has at least two recesses to form an axially extending locking arm 50 located between them. More preferably, the nut element 40 has two radially inwardly engaging locking arms 50 arranged opposite each other.

[0074] The locking arms 50 have a radially inwardly projecting locking projection 52. The locking arm 50 with locking projection 52 preferably establishes a releasable snap or detent connection with the connecting bolt 60 as soon as the connecting bolt 60 is axially inserted into the nut element 40 arranged in the cavity 14 of the hollow screw 10. This preferably pre-fixing connection between the nut element 40 and the connecting bolt 60 ensures a positioning movement of the connected parts in the radial direction within the cavity 14 of the hollow screw 10. The outer limit of the radial movement is determined by the inner diameter of the second opening 22 of the hollow screw 10.

[0075] To create the preferred snap-fit ​​connection between the nut element 40 and the connecting bolt 60, the snap-fit ​​projection 52 preferably engages in a recess 80 for pre-positioning the connecting bolt 60 on the nut element 40. To facilitate access to the recess 80, the snap-fit ​​projection 52 slides on a positioning ramp 82 into or towards the recess 80.

[0076] During pre-positioning or prior to assembly of the nut element 40 and connecting bolt 60 in the cavity 14, a guide cam 54 of the nut element 40 preferably engages in a guide groove 84 on the shaft 66, preferably extending in the axial direction of the connecting bolt 60. The engagement of the guide cam 54 in the guide groove 84 preferably provides relative axial guidance between the nut element 40 and the connecting bolt 60. Furthermore, the nut element 40 and the connecting bolt 60 are protected against rotation relative to each other. Accordingly, the positive locking connection between the guide cam 54 and the guide groove 84, as well as between the detent projection 52 and the recess 80, individually or jointly, acts as an anti-rotation device between the nut element 40 and the connecting bolt 60.

[0077] First, the hollow screw 10 is screwed into the opening O in component A. This is preferably done as a pre-positioning step for the connecting element 1 or as the first step in a joining process for the two components A and B. At this point, the nut element 40 is already pre-assembled with the connecting bolt 60 in the cavity 14 of the hollow screw 10, i.e., not yet permanently connected. This means that the connecting bolt 60 and the nut element 40 are pre-fixed to each other by at least one snap-fit ​​connection (see above). This pre-fixation ensures radial and partial axial movement of the connecting bolt 60 in the cavity 14.

[0078] The second connecting end 70 is then preferably fastened in the opening O of the second component B. Preferably, the second axial connecting end 70 and the opening O in the second component B form a quick-release or bayonet connection (see below).

[0079] The required radial position of the connecting bolt 60 within the second opening 22 of the hollow screw 10 preferably results from the connection of the hollow screw 10 to the first component A and the connecting bolt 60 to the second component B. Accordingly, radial tolerance compensation was achieved, supported by the preferably loose connection between the nut element 40 and the connecting bolt 60. This resulted in an adjustment of the radial position of the connecting bolt 60 in the connecting element 1 to the orientation of components A and B relative to each other.

[0080] After radial tolerance compensation, the radial position of the connecting bolt 60 in the hollow screw 10 is preferably fixed. For this purpose, a tool preferably transmits a torque to the nut element 40 via a drive feature 56 in the circumferential wall 42 of the nut element 40, preferably a recess on the radial outer side of the nut element 40. The resulting rotation of the nut element 40 on the shank 66 of the connecting bolt 60 causes the guide cam 54 to be guided via an insertion ramp 86 into a fixing position 88 in the shank 66 of the connecting bolt 60.

[0081] The preferential rotation of the nut element 40 guides the guide cam 54 over the insertion ramp 86 into the fastening position 88 on the connecting bolt 60. The movement of the guide cam 54 causes the connecting bolt 60 to be moved axially towards or into the nut element 40, while the nut element 40 is supported against the radial collar 26 in the cavity 14. The axial movement of the connecting bolt 60 towards the hollow screw 10 clamps the nut element 40 and the connecting bolt 60 against the radial collar 26 of the hollow screw 10 via its connecting flange 62, or frictionally fixes them in a specific radial position relative to the central longitudinal axis L of the hollow screw 10.

[0082] To illustrate the different radial positions that can be assumed for nut element 40 and connecting bolt 60, reference is made to the Figures 27 and 28referred to. In comparison to the circumferential wall 11 of the hollow screw 10, it can be seen that the nut element 40 and the connecting bolt 60 are held frictionally at different radial positions on the radial collar 26.

[0083] According to a preferred embodiment of the present invention, a sealing element 90 is provided on the connecting flange 62 of the connecting bolt 60. According to a preferred embodiment of the present invention, the sealing element 90 has a hat- or cup-shaped form with a base 92 and a circumferentially projecting wall 94. The opening of the sealing element 90, which results from the shape features, is preferably oriented towards the second connecting end 70 of the connecting bolt 60.

[0084] Since the sealing element 90 is preferably made of an elastic material, it conforms to the component B in a sealing manner when a connection is established, as described in the Figures 10 and17 shown.

[0085] According to the preferred embodiment in Figures 9 and 10 The base surface 92 is designed as a circular ring, the diameter of whose inner opening is determined by the diameter of the shaft 66 of the connecting bolt 60. The size of this base surface 92 has the advantage that the sealing element 90 is held between the connecting flange 62 and the adjacent contact surface 28 of the hollow screw 10 by friction or force. This results in a seal of the connecting element 1 to the outside.

[0086] To preferably enhance the sealing effect, the hollow screw 10 has the embossed rib 30. The annularly circumferential embossed rib 30 preferably projects beyond the contact surface 28 at the second axial end 20. As soon as the sealing element 90 is pressed against the embossed rib 30, the embossed rib 30 deforms the sealing element 90 and thereby preferably forms a type of labyrinth seal.

[0087] In the preferred embodiment of the sealing element 190 according to Figure 16 The circular ring of the base 192 is reduced to a radially inwardly projecting retaining collar. This provides a shaft-facing side of the connecting flange 62 for the friction-fit connection at the radial collar 26. Preferably, the connecting flange 62 has radial ribs 63 which are pressed into the contact surface 28 and / or the embossed rib 30 in the friction-fit connection with the nut element 40. In this way, additional positive-locking connections are formed that support the function of the connecting element 1.

[0088] Another preferred embodiment of the connecting element 101 is shown in perspective in the Figure 12 and 16 shown. Figure 13 shows only the three components of the connecting element 101 in a perspective exploded view, while in the Figures 14 and 15The connecting bolt 160 and the nut element 140 are shown separately.

[0089] As is also the case in Figure 1 The connecting element 1 shown as an example consists of a further preferred embodiment of the Figure 12 consisting of only three components. The connecting bolt 60; 160 with sealing element 90; 190 is considered a single component. Using only three components to provide the connecting element 1; 101 results in low manufacturing costs in terms of production, material costs, and assembly. Furthermore, this preferably reduces installation effort because the connection is limited to the hollow screw 10; 110 and the second connecting end 70; 170 of the connecting bolt 60; 160. This limitation of parts and the associated advantages apply to all connecting elements 1; 101; 201; 301 described herein.

[0090] In contrast to the previously described connecting element 1, the shank 166 of the connecting bolt 160 has an external thread 181 and the nut element 140 has a corresponding internal thread 149. Accordingly, the nut element 140 and the connecting bolt 160 are connected to each other by rotation.

[0091] The rotation is applied in a known manner via the drive feature 156 on the nut element 140 and / or via the drive feature 168 on the connecting bolt 160.

[0092] According to a preferred embodiment of the present invention, the external thread 181 of the connecting bolt 160 has at least one locking rib 183 for thread locking. Preferably, for pre-positioning or loosely arranging the connection between the nut element 140 and the connecting bolt 160 in the hollow screw 110, the nut element 140 is screwed onto the external thread 181 of the shaft 166. The nut element 140 is only screwed on to the extent that the internal thread 149 does not yet reach the locking rib 183. On this basis, the nut element 140 can still be positioned axially and, together with the connecting bolt 160, radially in the hollow screw 110.

[0093] To secure the connecting bolt 160 in a specific radial position on the radial collar 126 of the hollow screw 110, the nut element 140 is screwed completely onto the external thread 181. In this way, the connecting flange 162 and the nut element 140 clamp the radial collar 126 between them by friction or force-fit, as shown in Figure 17 This is shown. At the same time, this fixes the selected radial position of the connecting bolt 160, as shown in the Figures 27, 28 The locking rib 183 also preferably prevents the threaded connection between the nut element 140 and the connecting bolt 160 from loosening if no minimum torque is applied to overcome the thread locking.

[0094] Preferably, the Figures 16 and 17the installation process of the connecting element 101 already described above. After the connection consisting of nut element 140 and connecting bolt 160 has been pre-positioned in the hollow screw 110, the hollow screw 110 is screwed into the opening O of the first component A.

[0095] The movable connection consisting of nut element 140 and connecting bolt 160 is then preferably positioned radially so that the second axial connection end 170 of the connecting bolt 116 is aligned with the preferred keyhole S of the second component B.

[0096] By preferentially rotating the connecting bolt 160 via the drive feature 168, the second connecting end 170 is secured in the keyhole S.

[0097] Then, preferably using a tool, a torque is transmitted to the nut element 140 via a suitable positive fit with the drive feature 156 on the nut element 140. Turning the nut element 140 further screws the internal thread 149 onto the external thread 166 of the connecting bolt 160. The screwing process ends with an effective friction-fit connection or clamping of the connecting flange 162 and the nut element 140 on the circumferential radial collar 126 of the hollow screw 110. Preferably, the radial ribs 163 of the connecting flange 162 are also pressed into the embossed rib 130 to achieve additional positive fit.

[0098] The sealing element 190 already forms a sealing connection to the second component B when the second connection end 170 is connected.

[0099] According to a preferred embodiment of the connecting element 101, the nut element 140 is equipped with an axially projecting compression limiter 158. The compression limiter 158 projects from the nut element 140 in an annular shape towards the connecting flange 162. According to various preferred embodiments, the compression limiter 158 is a separate component (see Figure 18 ) or integrated into the nut element 140 (see Figure 19 ).

[0100] Due to the axial projection of the compression limiter 158 towards the connecting flange 162, the connecting flange 162 is preferably screwed onto a block with the compression limiter 158. This block screw connection limits the clamping force of the radial collar 126 of the hollow screw 110 between the nut element 140 and the connecting flange 162.

[0101] Another preferred embodiment of the connecting element 201 shows Figure 20In contrast to the embodiments 1 and 101 described above, the nut element 240 is permanently attached to the shank 266 of the connecting bolt 260. For this purpose, the nut element 240 is constructed similarly to a snap ring. Accordingly, the inner diameter of the nut element 240 is smaller than the outer diameter of the shank 266 of the connecting bolt 260.

[0102] The nut element 240 has an axially continuous gap 243 in the wall 242. This allows the approximately ring-shaped wall 242 to be widened in diameter to clamp the nut element 240 onto the shaft 266. The friction-fit connection achieved in this way between the shaft 266 and the nut element 240 ensures the equally friction-fit or force-fit connection between the connecting flange 262 and the nut element 240 at the radial collar 226 of the hollow screw 210.

[0103] To connect components A and B using the connecting element 201, the hollow screw 210 is first screwed into component A (step S1). The nut element 240 and the connecting bolt 260 are loosely connected to each other in the cavity 214 of the hollow screw 210.

[0104] By rotating the connecting bolt 260 via the drive means 268, the second connecting end 270 is fastened in the second component B (step S2).

[0105] In the meantime, the appropriate radial position of the connecting bolt 260 could be adjusted in alignment with the connected components A and B. To fix the selected radial position by clamping it on the radial collar 226 of the hollow screw 210 (step S3), the nut element 240, based on its clamping ring-like configuration, is moved along the shaft 266 as far as possible towards the connecting flange 262 using a suitable tool. Due to its clamping configuration, the nut element 242 maintains the frictional connection with the connecting bolt 260 in the radial position on the radial collar 226 and thus also preferentially fixes the radial position of the nut element 240 and connecting bolt 260 in the cavity 214.

[0106] Another preferred embodiment of the connecting element 301 is described in Figure 21The nut element 340 is designed as a non-releasable, locking ring structure, similar in design to the connecting element 201. Accordingly, the nut element 340 has a circumferential ring 341 with a plurality of locking lugs 345 extending axially from it. The locking lugs 345 extend in the direction of the drive feature 368 and bear against a locking projection 367 circumferentially on the shaft 366. The installation of the connecting element 301 is analogous to the installation of the connecting element 201 described above.

[0107] The connection method for the first component A and the second component B, already described above for the different preferred embodiments of the connecting element 1; 101; 201; 301, at a defined distance from each other, can be summarized in the following steps. In a first step S1, the hollow screw 10; 110; 210; 310 of the connecting element 1; 101; 201; 301 is screwed into the first fastening opening O on the first component A. Then, the second connecting end 70; 170; 270; 370 of the connecting bolt 60; 160; 260; 360 is fastened in a second fastening opening S of the second component B, whereby radial tolerances are compensated for in an axial alignment of the hollow screw 10; 110; 210; 310 and the connecting bolt 60; 160; 260; 360.In a further step, the nut element 40; 140; 240; 340 and the first connecting end 64; 164; 264; 364 of the connecting bolt 60; 160; 260; 360 are firmly connected to each other, so that the connecting bolt 60; 160; 260; 360 is attached to the hollow screw 10; 110; 210; 310.

[0108] According to a further preferred embodiment of the installation method, the hollow screw10; 110; 210; 310 in the first component A is rotated to adjust an axial position of the connecting element 1; 101; 201; 301.

[0109] According to a further preferred embodiment of the connection method, the nut element 40; 140; 240; 340 is loosened within the hollow screw 10; 110; 210; 310, then a radial position of the connecting bolt 60; 160; 260; 360 is changed relative to the hollow screw 10; 110; 210; 310, and then the nut element 40; 140; 240; 340 is reattached to the connecting bolt 60; 160; 260; 360.
