Abstract
Description
Technical Field
[0001] The present invention relates to a connecting assembly for connecting components and a vehicle device having such a connecting assembly. Background Technology
[0002] Vehicles have multiple connecting assemblies for linking two components, such as panel to vehicle body panel, headlight to vehicle body panel, etc. The parts and / or components of these connecting assemblies are increasingly being formed from plastic materials. In this case, due to mechanical stresses on the connecting assemblies caused by loads and stresses, and due to the so-called creep behavior (also known as flow behavior) of the plastic material, the parts may undergo time- and temperature-dependent plastic deformation. Summary of the Invention
[0003] The object of the present invention is to provide a connecting assembly (also called a connecting device) for connecting two components and a vehicle device having such a connecting assembly, which at least reduces or compensates for such creep.
[0004] The first objective of the invention is achieved by a connection structure having the features of claim 1. According to the invention, the second objective is achieved by a vehicle device having the features of claim 15.
[0005] For advantageous improvements, see the dependent claims.
[0006] The connecting assembly for connecting at least two components according to the invention includes at least one connecting unit and a nut element, wherein the connecting unit has a coupling interface to a first component and optionally a contact surface to a second component, wherein the coupling interface includes at least two coupling portions for coupling to the first component, wherein the connecting assembly can be fixed by means of the at least two coupling portions in a form-locking and / or force-locking manner, particularly pre-fixed to the first component.
[0007] The connecting unit specifically includes at least one base element and a compensation element that is threadedly engaged with the base element to compensate for tolerances, particularly component tolerances, such as radial and / or axial tolerances.
[0008] In particular, the connecting unit can be fixed without gaps by means of at least two coupling parts, especially pre-fixed to the first member, or fixed, especially pre-fixed.
[0009] The coupling interface between the connecting unit and the first component can be configured in a particularly seamless manner and in a form-locking and / or force-locking manner, so that all external forces acting on the connecting component are transmitted through the coupling interface.
[0010] For example, the coupling interface can be pre-fixed to the first member without gaps in at least two spatial directions by means of at least two coupling portions. In particular, the connecting unit can be directly connected to the first member by means of form-locking and / or force-locking through the coupling portions.
[0011] In this case, the coupling interface for pre-assembly and pre-connection, as well as for gapless connection in a form-locking and / or force-locking manner, can be in at least two spatial directions, particularly in the z and x directions. In each case, a coupling portion is provided on the first member, which may be assigned a mating coupling interface on the first member, such that a form-locking and / or gapless connection with the first member can be formed, particularly in the z and x directions.
[0012] Preferably, the connection unit formed by the base element and the compensation element is arranged in such a way that it can be pre-assembled on the first component (also called the interface, especially the client interface) with an axial offset in the spatial direction.
[0013] For example, the connecting unit may be pre-assembled in and / or on the first member by means of a coupling portion, such that an axial offset is formed in at least one spatial direction between the interface opening of the connecting unit and the first member and / or between the screw element to be inserted and the interface opening. The axial offset is understood as the spatial offset of the longitudinal axis of the connecting unit relative to the longitudinal axis of the first member, for example, an offset in the x-direction. Therefore, the axial offset is a parallel offset.
[0014] When connecting two components, particularly when inserting a screw element, the screw element extends through the connecting unit and at least partially enters the interface opening in the first component due to axial offset. Optionally or additionally, the screw element may abut the edge of the interface opening in the first component due to axial offset.
[0015] When two components are connected, the second component is positioned without gap relative to the first component (i.e., the interface) by means of a connecting unit. For example, when connecting two components to center the connecting unit and / or screw element relative to the first component and eliminate axial offset, the second component and / or screw element, along with the connecting unit, can be pressed into the center position relative to the interface opening. Therefore, the screw element can be inserted into the interface opening and screwed into the nut element. As a result, the second component is positioned without gap relative to the first component.
[0016] Furthermore, when the screw element is fixed to the nut element and / or when the two components are connected, the connecting unit can be fixed to the first component without gaps by means of the coupling portion, for example on all three axes.
[0017] In other words: When the two components are connected, the axial offset between the connecting unit and the first component is compensated. The second component is locked to the first component in the spatial direction of the axial offset via the connecting unit. Specifically, when the two components are connected, movement of the second component in the direction opposite to the spatial direction of the axial offset, particularly in the -x direction, is prevented. Therefore, the second component can no longer be removed from the first component in the -x direction, and in particular, it cannot be pushed out.
[0018] The connecting unit can be clamped to the nut element by means of a screw element. In particular, the screw element can clamp the second member, the connecting unit, and the nut element together. As a result, the first member is not in the force flow of the screw element.
[0019] In other words, in the assembled state where two components are connected by a connecting unit, the connecting unit, along with the resulting compensating element and base element, is clamped to the nut element by means of a screw element and is located in the force flow between the screw element and the nut element. In this case, the prestress is directly transmitted from the nut element to the connecting unit, and in particular to the base element, such that the coupling portion of the connecting unit is not located in the force flow between the screw element and the nut element, and therefore not in the force flow of the prestress.
[0020] Then, the working force acting on the connection acts on the first component and the connection unit, especially on the form-locking and / or force-locking connection between the base element.
[0021] In other words, the connecting assembly can be configured such that all external forces acting on the connecting assembly are transmitted through the coupling interface, thereby transmitting the force through the coupling between the connecting unit and the first member, particularly through the form-locking and / or force-locking and gapless connection between the coupling portion and the first member. In other words, all externally acting forces (also known as working forces) are absorbed by the coupling interface. No prestress acts on the coupling interface for the screw element. Therefore, the loss of prestress is eliminated through the inflow at the interface. Thus, the connection is designed to be sustainable. Prestress acts only on the nut element.
[0022] For example, the corresponding coupling portion can be wedge-shaped. The corresponding mating coupling portion on the first member can be configured, for example, as a recess, groove, and / or post-engagement. In this way, post-engagement of the connecting unit with the first member, particularly form-locking pre-connection, can be achieved.
[0023] The shape of the corresponding coupling part can be, for example, trapezoidal, wedge-shaped, L-shaped, T-shaped, dovetail-shaped, etc. The shape of the subsequent joint or the recess / groove of the mating coupling interface can be, for example, wedge-shaped, groove-shaped, dovetail groove-shaped, etc.
[0024] In particular, in the coupled state, the coupling interface and the mating coupling interface can form a shape-locking and / or force-locking connection, such as a dovetail connection, for example by wedge teeth (dovetail / tenon) in a suitable recess / groove (tail-groove / mortise).
[0025] In this configuration, the coupling portion of the connecting unit and the corresponding mating coupling portion on the first member can be specifically constructed in such a way that, in the assembled state of the connecting unit on the first member, the connecting unit and the first member form a gapless connection in all three spatial directions, particularly in the longitudinal, vertical, and transverse directions, thereby achieving a gapless connection in all three axial directions. Specifically, for this purpose, during pre-assembly onto the first member, the connecting unit is pressed into the cavity of the first member in all three spatial directions, such that any existing tolerances are compensated or offset, and the connecting unit is pre-assembled onto the first member gaplessly, thus without any freedom of movement.
[0026] For example, the coupling portion of the connecting unit and the corresponding mating coupling portion on the first member can be specifically configured to form a clamping connection. In particular, they can form a wedge-shaped clamping connection with each other, such as a dovetail connection, an undercut connection, etc.
[0027] Furthermore, the connecting unit can be pre-fixed to the first member with an axial offset relative to the longitudinal axis of the first member. As a result, when the members are connected, the screw element and / or the second member abuts or presses against or presses against the first member, thereby pressing the first member against the connecting unit, thus placing them relative to each other without gaps. In particular, the first member and the connecting unit are thus locked to each other.
[0028] In this configuration, the nut element can be arranged, for example, in the free space between the connecting unit and the first member. The nut element can be constructed separately. Alternatively, the nut element can be an integrated part of the connecting unit or the first member.
[0029] The advantages achieved by this invention are particularly that they at least reduce or even avoid the flow behavior or creep of the components of the connecting assembly, especially in the coupling interface region between the connecting unit and the first member, for example in the region of the overmolded fastening nut.

[0060] The same parts in all the accompanying drawings are indicated by the same reference numerals. Detailed Implementation
[0061] Figure 1 An exploded view of the connecting component 1 and the first member 2 is shown schematically.
[0062] The connecting assembly 1 is configured as a tolerance compensation device. The connecting assembly 1 includes a connecting unit 1.1, which is configured as a tolerance compensation element 1.2. Optionally, the connecting unit 1.1 may also be configured as a threaded connection.
[0063] The connecting assembly 1 includes a connecting unit 1.1, a nut element 4, and a screw element 6, particularly a threaded bolt or connecting screw.
[0064] The connecting unit 1.1 has a coupling interface 1.1.1 to the first component 2 and a contact surface 1.1.2 to the second component 8 (e.g., ...). Figure 5 (As shown).
[0065] The coupling interface 1.1.1 may include at least two coupling portions 1.4 for coupling to the first member 2. The connecting component 1 can be pre-fixed to the first member 2 without gaps and in a form-locking manner by means of at least two coupling portions 1.4. For example, the coupling interface 1.1.1 can be pre-fixed to the first member 2 without gaps in a form-locking manner in at least two spatial directions by means of at least two coupling portions 1.4. In particular, the connecting unit 1.1 can be directly connected to the first member 2 through the coupling portions 1.4 in a form-locking and / or force-locking manner.
[0066] The connecting unit 1.1 can also be clamped to the nut element 4 by means of the screw element 6. Specifically, the screw element 6 can clamp the second member 8, the connecting unit 1.1, and the nut element 4. As a result, as... Figure 17 As shown, the first component 2 is not located in the force flow of the screw element 6.
[0067] The coupling interface 1.1.1 is configured for pre-assembly and pre-connection to the first member 2 in at least two spatial directions, particularly in the lateral direction z and the longitudinal direction x. For this purpose, the coupling interface 1.1.1 has at least one coupling portion 1.4 which may be assigned a corresponding mating coupling portion 2.1 on the first member 2, thereby forming a form-locking and gapless connection with the first member 2.
[0068] For example, the corresponding coupling portion 1.4 can be wedge-shaped. The corresponding mating coupling portion 2.1 on the first member 2 can be configured, for example, as a recess and / or post-engagement, particularly as a groove 2.1.1. In this way, a post-engagement, particularly a form-locking pre-connection, can be formed between the connecting unit 1.1 and the first member 2.
[0069] In particular, in the coupled state, coupling interface 1.1.1 and mating coupling interface 2.0 can form a shape-locking connection, such as a dovetail connection, for example, through wedge teeth in a suitable recess / groove (tail).
[0070] The shape of the corresponding coupling part 1.4 can be, for example, trapezoidal, wedge-shaped, L-shaped, T-shaped, dovetail-shaped, etc. The shape of the subsequent joint or the shape of the recess of the mating coupling part 2.1 can be, for example, wedge-shaped, groove-shaped, dovetail groove-shaped, etc.
[0071] In this case, the coupling portion 1.4 of the connecting unit 1.1 and the corresponding mating coupling portion 2.1 on the first member 2 can be constructed in such a way that, in the assembled state of the connecting unit 1.1 on the first member 2, the connecting unit 1.1 and the first member 2 form a gapless connection in all three spatial directions, particularly in the longitudinal direction x, the vertical direction y, and the transverse direction z.
[0072] Specifically, for this purpose, during pre-assembly onto the first component 2, the connecting unit 1.1 is pressed into the cavity 2.2 of the first component 2 in all three spatial directions, such that the existing tolerance 200 (e.g., Figure 5 (As shown) will be compensated or compensated, and the connecting unit 1.1 is pre-assembled onto the first member 2 without gaps, so there is no freedom of movement.
[0073] For example, the coupling portion 1.4 of the connecting unit 1.1 on the first component 2 and the corresponding paired coupling portion 2.1 can be specially configured to form a clamping connection with each other, especially a wedge clamping connection, such as a dovetail connection, an undercut connection, etc.
[0074] The connecting assembly 1, configured as a tolerance compensation device, is used to connect two components 2 and 8 (e.g. Figure 5 As shown), while compensating for tolerances of 200, especially axial and / or radial tolerances of 200 (as shown). Figure 5 (As shown).
[0075] The connecting component 1 is used, for example, in a vehicle to connect two components 2, 8, particularly vehicle components such as a headlight and a vehicle metal panel, especially for connecting the headlight to the vehicle metal panel (also known as the vehicle skin), while compensating for a tolerance of 200.
[0076] The connecting unit 1.1, configured as tolerance compensation element 1.2, includes at least one base element 1.1.3, particularly a hollow cylindrical sleeve with internal or external threads, and a compensation element 1.1.4 threadedly engaged with the base element 1.1.3, wherein the compensation element 1.1.4 can be moved by rotation relative to the base element 1.1.3 to compensate for tolerance 200.
[0077] The base element 1.1.3 includes an integrated retaining portion 1.5. The retaining portion 1.5 is configured as an integrated retaining bracket 1.5.1, which can be movably, particularly slidably, inserted into the first member 2. Furthermore, the base element 1.1.3 includes a receiving portion 1.6 having a receiving cavity 1.6.1 into which the nut element 4 can be inserted.
[0078] Furthermore, the connecting unit 1.1 includes a drive element 1.1.7. The drive element 1.1.7 is configured as a follower element. Additionally, the drive element 1.1.7 can also be configured as a seal. Specifically, the drive element 1.1.7 is configured as a plastic element and is separate. In cross-section, the drive element 1.1.7 has a T-shape, with a cylindrical follower portion 1.1.7.1 and a flange 1.1.7.2 serving as a contact surface 1.1.2. The drive element 1.1.7 is elastic, such that it can also be configured as a follower element or follower spring of the compensating element 1.1.4.
[0079] Tolerance compensation element 1.2 is the conventional compensation element 1.1.4, as described, for example, in the older DE 10 2023205 661.5.
[0080] As described in detail below with reference to the other accompanying drawings, the pre-assembled connecting component 1 is pre-assembled without gaps on the first member 2 and is subsequently positioned relative to the second member 8, or conversely, the second member 8 is positioned relative to the connecting component 1 for connection.
[0081] Subsequently, the screw element 6 for tightening components 2 and 8 is guided through the corresponding openings in components 2 and 8 and through the connecting assembly 1 (such as...). Figure 6 (As shown). When screw element 6 is tightened, compensation element 1.1.4 rotates relative to base element 1.1.3 via drive element 1.1.7 connected between screw element 6 and compensation element 1.1.4, thereby axially moving relative to base element 1.1.3 from its initial position, for example, moving away from base element 1.1.3, until it reaches its compensation position, in which base element 1.1.3 and compensation element 1.1.4 each rest against one of members 2 and 8, thereby bridging the connection gap and compensating for tolerance 200 (as shown). Figure 9 (As shown).
[0082] Figure 2 A perspective view of the pre-assembled connecting assembly 1 is schematically shown. In this case, the nut element 4 is arranged in the receiving cavity 1.6.1. The nut element 4 includes an abutment flange 4.1, which directly abuts the underside of the base element 1.1.3, particularly the underside of the retaining bracket 1.5.1. Furthermore, a washer may be arranged between the nut element 4 and the base element 1.1.3.
[0083] The compensation element 1.1.4 is disposed on the base element 1.1.3.
[0084] The base element 1.1.3 may include a first coupling portion 1.4.1 as the front portion and a second coupling portion 1.4.2 as the rear portion.
[0085] On the side, the retaining bracket 1.5.1 has guide ribs 1.5.2 and coupling portions 1.4, particularly the first coupling portion 1.4.1 and the second coupling portion 1.4.2 formed thereon.
[0086] Figure 3 It schematically shows the following based on Figure 2 Exploded view of the pre-assembled connecting component 1 and the first component 2.
[0087] The connecting assembly 1 is constructed as a retaining bracket 1.5.1 by means of a retaining portion 1.5 being introduced into the cavity 2.2. On the side, the first member 2 has two opposing grooves 2.1.1 on its inner wall 2.3, serving as guide grooves 2.4 for guiding the retaining bracket 1.5.1. Guide ribs 1.5.2 can be inserted into the guide grooves 2.4.
[0088] Figure 4 A perspective view of the pre-assembled connecting component 1 is schematically shown, which is in turn pre-assembled seamlessly onto the first component 2, as described in more detail below.
[0089] Figure 5 It schematically shows the following based on Figure 4 The cross-section of the connecting assembly 1, pre-assembled on the first component 2 and pre-positioned relative to the second component 8, is used to compensate for a tolerance of 200.
[0090] The compensating element 1.1.4 is used to compensate for the first axial tolerance 202 in the vertical direction y between the second member 8 and the first member 2. The connecting unit 1.1 compensates for the second axial tolerance 204 in the longitudinal direction x by means of the retaining portion 1.5.
[0091] Therefore, the connecting unit 1.1 can be pre-fixed to the first member 2 with an axial offset 201 relative to the longitudinal axis of the first member 2.
[0092] In this configuration, the nut element 4 can be arranged, for example, in the free space 12 between the connecting unit 1.1 and the first member 2. The nut element 4 can be designed separately. Alternatively, the nut element 4 can be an integrated part of the connecting unit 1.1 or the first member 2.
[0093] The connecting unit 1.1 is pre-assembled on the first component 2, wherein the second axial tolerance 204 has not been compensated or reduced during pre-assembly. These tolerances 200 (also referred to as clearances) are only applied when the screw element 6 (such as...) is... Figure 6When tightened onto the two components 2 and 8 (as shown), the damage is compensated or at least reduced by connecting to the nut element 4.
[0094] Figure 6 This schematically illustrates the use of, according to Figure 5 The connecting component 1 connects the two components 2 and 8 and provides a first axial tolerance 202 for compensating for the second component 8 and the connecting unit 1.1 / first component 2 (e.g., Figure 5 The screw element 6 is shown in the cross-section of its introduction. Due to the aforementioned axial offset 201, at least one edge 2.6.1 of the screw element 6 adjacent to the interface opening 2.6 in the first member 2 protrudes into the interface opening 2.6 (also as shown). Figure 29 (As shown). When the screw element 6 is further connected to the first member 2, the second member 8 and / or the screw element 6 are pressed in the direction of the interface opening 2.6 in the first member 2 so as to align, in particular, center, with respect to the interface opening 2.6. In this case, the first member 2 presses against the connecting unit 1.1, or conversely, the connecting unit 1.1 and the second member 8 press against the first member 2 so that they are aligned, in particular, center, and positioned relative to each other without gaps. In this case, the first member 2 and the connecting unit 1.1 interlock, for example by means of a form-locking and / or force-locking connection, in particular by means of a press-fit interlock.
[0095] With the two components 2 and 8 connected, the axial offset 201 between the connecting unit 1.1 and the first component 2 (e.g.) Figure 5 (As shown) is compensated. The second member 8 is locked to the first member 2 in the spatial direction x of the axial offset 201 via the connecting unit 1.1. In particular, in the connected state of the two members 2 and 8, movement of the second member 8 in the opposite direction with respect to the spatial direction x of the axial offset 201 is prevented, especially in the -x direction (e.g., Figure 7 (As shown). Therefore, the second component 8 can no longer be removed from the first component 2 in the -x direction, in particular, it can no longer be pushed out.
[0096] Figure 7 The cross-section of the connection between the connecting unit 1.1 and the first member 2 is schematically shown. When the two members 2 and 8 are connected, the connection achieves clamping, particularly wedge clamping.
[0097] Due to the second axial tolerance 204, during the connection process, the screw element 6 can press against the coupling interface 1.1.1, as shown by arrow 300, and / or press against the drive element 1.1.7, as shown by arrow 302.
[0098] In this configuration, the screw element 6 presses the connecting unit 1.1 against the mating coupling portion 2.1 in the first member 2 without any clearance. The mating coupling portion 2.1 is configured as an end stop 2.5 (as shown in the image). Figure 10 and 11 (As shown). As a result, the corresponding coupling portions 1.4, 1.4.1, and 1.4.2 form a shape-locking and gapless connection with the mating coupling portion 2.1 in the first member 2 in at least two spatial directions, particularly in the lateral direction z and / or the longitudinal direction x. Therefore, the first member 2 and the connecting assembly 1 are locked relative to each other and to each other, so that the first member 2 cannot move in the longitudinal direction x. For this purpose, the corresponding mating coupling portion 2.1 can be configured as undercut, step, recess, wedge, inclined surface, protrusion, etc.
[0099] Figure 8 It schematically shows the following based on Figure 7 The magnified details of the cross-section show that in the region of the coupling interface 1.1.1, there is a coupling portion 1.4 of the connecting unit 1.1 and the first member 2, wherein the connecting component 1 is connected to the first member 2 without gaps, with tolerance compensation and clamping.
[0100] Figure 9 The cross-sections of two components 2 and 8 are schematically shown, which are connected to each other without gaps, with tolerance compensation, and in a segmented clamping manner.
[0101] Another interface 1.1.5 of the connecting unit 1.1 is formed to the second member 8 in the area of the contact surface 1.1.2 of the connecting unit 1.1.
[0102] Screw element 6 clamps the other interface 1.1.5 of connecting unit 1.1 and nut element 4 together.
[0103] The coupling interface 1.1.1 is not in the first force flow 400 of the screw element 6 (e.g.) Figure 17 (As shown).
[0104] Figure 10 A cross-sectional view of the coupling interface 1.1.1 is schematically shown, which has multiple coupling portions 1.4, particularly a front coupling portion 1.4.1 and a rear coupling portion 1.4.2, between the connecting unit 1.1, particularly its retaining portion 1.5 and the first member 2.
[0105] Figure 11 Another cross-sectional view of the coupling interface 1.1.1 is schematically shown, which has multiple coupling portions 1.4, particularly the front coupling portion 1.4.1 and the rear coupling portion 1.4.2, between the connecting unit 1.1, particularly its retaining portion 1.5 and the first member 2.
[0106] The coupling interface 1.1.1 is configured as a form-locking and gapless connection between the connecting unit 1.1 and the first member 2, particularly as a dovetail connection between the base element 1.1.3 and the first member 2. This dovetail connection reduces creep (also known as relaxation) of the plastic-containing components.
[0107] For example, the corresponding coupling portion 1.4, particularly coupling portions 1.4.1 and 1.4.2, can be wedge-shaped. The corresponding mating coupling portion 2.1 on the first member 2 can be configured, for example, as recessed and / or post-engaged. In this way, a post-engagement, particularly a form-locking pre-connection, can be formed between the connecting unit 1.1 and the first member 2.
[0108] The shape of the corresponding coupling part 1.4 can be, for example, trapezoidal, wedge-shaped, L-shaped, T-shaped, dovetail-shaped, etc. The shape of the subsequent joint or the shape of the recess of the mating coupling interface 2.1 can be, for example, wedge-shaped, groove-shaped, dovetail groove-shaped, etc.
[0109] In this case, the coupling portion 1.4 of the connecting unit 1.1 and the corresponding mating coupling portion 2.1 on the first member 2 can be constructed in such a way that, in the assembled state of the connecting unit 1.1 on the first member 2, the connecting unit 1.1 and the first member 2 form a gapless connection in all three spatial directions, particularly in the longitudinal direction x, the vertical direction y, and the transverse direction z.
[0110] Specifically, for this purpose, during pre-assembly onto the first component 2, the connecting unit 1.1 is pressed into the cavity 2.2 of the first component 2 in all three spatial directions (e.g., Figure 1 As shown), the existing tolerance 200 will be compensated or compensated, and the connecting unit 1.1 is gapless and clamped, so it is pre-assembled onto the first member 2 without any freedom of movement.
[0111] For example, the coupling portion 1.4 of the connecting unit 1.1 on the first component 2 and the corresponding paired coupling portion 2.1 can be specially configured to form a clamping connection with each other, especially a wedge clamping connection, such as a dovetail connection, an undercut connection, etc.
[0112] Figure 12 An enlarged perspective view of the wedge-shaped coupling portion 1.4 is schematically shown, wherein the wedge-shaped rear coupling portion 1.4.2 is on the connecting unit 1.1. The wedge-shaped rear coupling portion 1.4.2 serves as a mating stop for the end stop 2.5 on the first member 2 (e.g., Figure 10 and 11 (as shown), especially for the clamping connection of the latter.
[0113] Figure 13An enlarged perspective view of another wedge-shaped front coupling portion 1.4.1 at the connecting unit 1.1 is schematically shown.
[0114] Due to the different wedge shape of the front coupling portion 1.4.1, the first member 2 is pressed and clamped into all axes (x, y, z) without gaps relative to the connecting unit 1.1, and especially relative to the retaining portion 1.5.
[0115] Figure 14 An enlarged perspective view of another wedge-shaped mating coupling portion 2.1 on the first member 2 is schematically shown. The mating coupling portion 2.1 is configured, for example, as a wedge-shaped surface 2.1.2 in a groove 2.1.1. The mating coupling portion 2.1 rises from the first member 2 along the transverse direction z and the vertical direction y. The mating coupling portion 2.1 is particularly flexible. For example, the mating coupling portion 2.1 can be configured as a compression rib. In this way, a free clearance is easily and safely created.
[0116] Figure 15 An enlarged cross-sectional view schematically illustrates the gapless, tensioned connection between the first coupling portion 1.4.1 and the first mating coupling portion 2.1.3, which is configured, for example, as a wedge-shaped surface 2.1.2, particularly as a compression rib or a flexible rising surface.
[0117] Figure 16 An enlarged cross-sectional view schematically illustrates the gapless, tensioned connection between the second coupling portion 1.4.2 and the second mating coupling portion 2.1.4, which is configured, for example, as a wedge-shaped surface 2.1.2, particularly as a compression rib or a flexible rising surface.
[0118] Figure 17 A schematic cross-sectional view of the connected components 2 and 8 is shown, where a first force flow 400 of prestress 500 (also referred to as clamping force) acts on another interface 1.1.5. In this case, screw element 6 clamps the other interface 1.1.5 of connecting unit 1.1 on the second component 8 and nut element 4 together. The coupling interface 1.1.1, and therefore the coupling between connecting unit 1.1 and the first component 2, is not in the first force flow 400 of screw element 6. Prestress 500 is transmitted directly from nut element 4 to base element 1.1.3. This reduces possible creep or relaxation of the plastic components.
[0119] Figure 18 Another cross-sectional view of the connecting components 2 and 8 is schematically shown, in which a second force flow 402 of working force 502 (also referred to as balancing force / motion force) acts on the coupling interface 1.1.1 between the base element 1.1.3 and the first component 2. Working force 502 specifically refers to the force acting on the connecting component 1 from the outside, such as motion force, balancing force, etc.
[0120] The working force 502 is generated by the shape-locking connection between the connecting unit 1.1 and the first component 2, particularly the dovetail connection.
[0121] In this configuration, the connecting assembly 1 is arranged such that all external forces acting on it are transmitted through the coupling interface 1.1.1, thereby transmitting the force through the coupling of the connecting unit 1.1 to the first member 2, particularly through the form-locking and gapless connection between the coupling portion 1.4, especially the front / rear coupling portions 1.4.1 and 1.4.2, and the first member 2. In other words, all external forces (also known as working forces) are absorbed by the coupling interface 1.1.1. No prestress is applied to the screw element 6 by the coupling interface 1.1.1. Therefore, prestress loss is eliminated by introducing the coupling interface 1.1.1.
[0122] Figure 19 A cross-sectional view of the alternative connecting component 1' is shown schematically.
[0123] Figure 20 It schematically shows the following based on Figure 19 Perspective view of the alternative connection component 1'.
[0124] The difference in the alternative connecting assembly 1' is that the compensating element 1.1.4 consists of a sleeve portion and a bearing ring. The driving element 1.1.7 is constructed as a spring element. The base element 1.1.3 is constructed as a cylindrical hollow element. The retaining portion 1.5 is constructed as a retaining ring 1.5.3 having a plate 1.5.4 that can be fixed to the retaining ring 1.5.3. The nut element 4 is arranged and held in the receiving portion 1.6 of the retaining portion 1.5, forming the coupling portion 1.4.
[0125] Figure 21 A cross-sectional view of another alternative connecting component 1” is schematically shown.
[0126] Figure 22 It schematically shows the following based on Figure 21 A perspective view of another alternative connection component 1".
[0127] The difference in “Alternative Connection Assembly 1” is that the compensating element 1.1.4 and the drive element 1.1.7 are integrally formed in the peripheral U-shaped collar therein. The drive element 1.1.7 is configured as a spring element. The base element 1.1.3 is configured as a cylindrical hollow element with an integrated retaining bracket 1.5.1. The nut element 4 is integrated into the base element 1.1.3 as an internal thread 10.
[0128] Figure 23 A perspective view of another alternative connection component 1″′ is schematically shown.
[0129] The difference between the alternative connecting component 1″′ is that the retaining bracket 1.5.1 has a tapered guide rail 1.5.5 for allowing free clearance and for the clamping arrangement and pre-connection of the connecting unit 1.1 on the first member 2.
[0130] Figure 24 A perspective view of another connection unit 1.1 with an alternative coupling interface 1.1.1 is schematically shown.
[0131] The connecting unit 1.1 is similar to the connecting unit 1.1 described above, including a base element 1.1.3 and a compensation element 1.1.4.
[0132] The coupling interface 1.1.1 can be an integral part of the base element 1.1.3. Alternatively, the coupling interface 1.1.1 can be constructed separately.
[0133] Furthermore, the seal 14 may be disposed on the end side of the connecting unit 1.1. The seal 14 is formed, for example, of a soft plastic material, particularly a thermoplastic elastomer (TPE), rubber, or another similar material. The seal 14 is particularly disposed along the direction of the second member 8 (e.g., Figure 5 and 6 (As shown) is arranged on the connecting unit 1.1, particularly on the base element 1.1.3. The seal 14 may be annular. The seal 14 may be formed in a T-shape in cross-section and partially extend into the through hole 16 of the base element 1.1.3. The seal 14 may be constructed as a separate element. The seal 14 may be an integral part of the base element 1.1.3. For example, the seal 14 may be injection molded onto the base element 1.1.3.
[0134] Furthermore, the connecting unit 1.1 may have a stop 18. The stop 18 extends radially outward as a web at the end side of the connecting unit 1.1.
[0135] The coupling interface 1.1.1 includes rib 20 as a coupling portion 1.4. Rib 20 is configured as a short side rib 20.1, for example, in the retaining portion 1.5 of the retaining bracket 1.5.1, and / or as a longitudinal rib 20.2 on the underside (e.g., Figure 25 (As shown). As described above, the retaining bracket 1.5.1 may have a plate 1.5.4 with a transverse tapered guide rail 1.5.5, by means of which the retaining bracket 1.5.1 can be assembled in the first member 2. Side ribs 20.1 are specifically arranged on the outside of the tapered guide rail 1.5.5.
[0136] In the assembled or coupled state on the first component 2 (e.g.) Figure 27 and 28As shown), the additional rib 20 forms a multi-force locking connection with the first member 2, particularly a press fit, a friction lock connection, a clamping connection, etc. In particular, the connecting unit 1.1 can therefore be fixed to the first member 2 at the bottom and side in the assembled state, especially by press fit.
[0137] Furthermore, the connecting unit 1.1 may have a stop surface 22. The stop surface 22 extends vertically upward from the retaining bracket 1.5.1.
[0138] Figure 25 It schematically shows the following based on Figure 24 Another perspective view of another connecting unit 1.1. Figure 26 A cross-sectional view of another connecting unit 1.1 is schematically shown, which has a base element 1.1.3 and a compensation element 1.1.4, which are threadedly engaged with each other 30.
[0139] In addition, the connecting unit 1.1 may include a transport safety device 24 and / or an end stop 26. The transport safety device 24 ensures that the base element 1.1.3 and the compensation element 1.1.4 do not disengage from each other during transport. During the compensation movement to compensate for the axial tolerance 200, the end stop 26 is used to limit the movement of the compensation element 1.1.4 relative to the base element 1.1.3.
[0140] Transport safety devices 24 and / or end stops 26 are arranged and formed inside the connecting unit 1.1. These are, in particular, for example, corresponding protruding webs, protruding noses, protruding lips, etc., in the end-side grooves 28 of the base element 1.1.3 on the opposite end faces of the base element 1.1.3 and the compensating element 1.1.4 or the seal 14.
[0141] Side ribs 20.1 are arranged as short ribs 20 at the widened tapered end of tapered guide rail 1.5.5. Longitudinal ribs 20.2 extend beyond the entire underside of retaining bracket 1.5.1.
[0142] The connecting unit 1.1 may also be provided with an internal thread 10 for the screw element 6 (e.g., Figure 6 (As shown).
[0143] Figure 27 It schematically shows the following based on Figure 24 An exploded view of another connecting unit 1.1 and the first component 2, wherein connecting unit 1.1 is pre-assembled on the first component 2 by means of coupling interface 1.1.1, similar to the previously referenced Figures 1 to 23 Other descriptions in the text. Figure 28 A perspective view of another connecting unit 1.1 and the first component 2 in a coupled state, particularly in a pre-fixed state, is schematically shown. Figure 29 The method sequence for connecting the second component 8 to the connecting unit 1.1 and the first component 2 is illustrated schematically.
[0144] In this case, the connecting unit 1.1 is inserted into the first member 2 by means of the retaining bracket 1.5.1 according to arrow 304, in particular into the mating coupling interface 2.0, until the coupling portion 1.4 of the coupling interface 1.1.1 of the connecting unit 1.1 is fixed to the first member 2 in at least two spatial directions, particularly in the longitudinal direction x and the vertical direction y, by form locking and / or force locking, in particular by means of the press fit of the rib 20.
[0145] Figure 29 The aforementioned axial offset 201 is shown in detail, which is compensated for during the connection of components 2 and 8 by moving the second component 8 and / or the screw element 6, while centering the screw element 6 on the interface opening 2.6 of the first component 2.
