Description

Technical Field

[0001] This invention relates to a wiring guide device for connecting a wiring harness to a carrier element capable of movement relative to a vehicle, according to the features described in the preamble of claim 1. Furthermore, the invention is also implemented in combination with saddle trailers, trailers, or articulated vehicles. Background Technology

[0002] A saddle-type train typically consists of a tractor and a saddle-type trailer, which are releasably connected to each other via a saddle coupler mounted on the tractor and a kingpin mounted on the saddle-type trailer. This allows a saddle-type trailer connected to the tractor to be parked and, in turn, received at the same location as another saddle-type trailer. For such a disengagement process, the driver usually must dismount and mechanically open the saddle coupler to disengage, or check the locking status of the kingpin correctly engaged in the saddle coupler after coupling.

[0003] Articulated trains typically consist of a tractor and a trailer hooked to it, with the trailer releasably secured to the trailer coupler of the tractor via a drawbar.

[0004] For example, an articulated vehicle is a folding articulated bus used in short-distance public transportation. Articulated vehicles can also be, for example, wheel loaders, road rollers, or folding articulated dump trucks. What articulated vehicles have in common is that they are designed with first and second vehicle components and a pivoting hinge between them. During operation, the first and second vehicle components cannot be separated from each other. When the articulated vehicle turns, the first and second vehicle components change their position relative to each other.

[0005] In the past, efforts have been made to automate processes such as the hooking and unhooking of saddle trailers and tractors, and connections to supply lines have also been established. For example, DE 10 2004 024 333A1 discloses a plug-in coupling system in which, during hooking of the saddle trailer and tractor, a wedge-shaped pivoting frame, pivotally supported relative to the kingpin, moves into the insertion opening of the saddle coupler and remains there after the kingpin is locked. During cornering of the saddle trailer, the wedge-shaped pivoting frame pivots relative to the saddle trailer, so the supply line must be measured accordingly to prevent tearing during sharp turns. However, when traveling straight, the supply line may sag and potentially be damaged.

[0006] For this reason, DE 10 2004 044 992 A1 recommends installing a wiring harness on a saddle trailer, in which supply lines extending from a wedge-shaped pivot frame are wound around a spring-preloaded drum and unwound under stress during cornering. The main disadvantage of this known wiring harness is the relatively large structural space requirement and the problem that a wiring harness with an ever-increasing number of supply lines must be mounted on the drum to ensure that the minimum permissible bending radius for the wiring harness is not exceeded. Summary of the Invention

[0007] The objective of this invention is to provide a compact line guiding device suitable for ensuring minimal sag in wire harnesses with large diameters.

[0008] According to the invention, this task is solved using the features of claim 1. The spring element is understood as a reversible component under the expected operating load, extending in its axial direction between a maximum length and a minimum length. In principle, the spring element can be made of spring steel, plastic, or a rubber compound. In principle, the wiring harness is always loosely placed in, at, or on the spring element and is not connected to it.

[0009] The term "loosening" is understood as the mechanical separation of the spring element and the wiring harness. Therefore, the spring element can extend or shorten independently of the wiring. Relative movement relative to the spring element can occur in the axial direction of the wiring harness. The wiring harness is supported by the spring element and overcomes only sliding friction caused by its own weight for axial movement. In the radial direction, the wiring harness is guided through the spring element with a small degree of movement.

[0010] During cornering, the carrier element changes its relative position to the wiring storage, increasing the distance between the carrier element and the wiring storage, and the wiring harness must cross this greater distance. In this case, a portion of the wiring harness located in the wiring storage is pulled out of the wiring storage by the carrier element. If the vehicle resumes straight-line travel, the distance between the carrier element and the wiring storage decreases, and the wiring harness needs to cross a smaller distance. In this case, the wiring harness is partially moved back into the wiring storage by the carrier element.

[0011] The spring element ensures that the wiring harness is always supported and does not sag downwards, thus preventing it from colliding with other vehicle components. During the insertion movement of the wiring harness into the wiring storage container, the spring element prevents the wiring harness from moving laterally out and ensures a smooth entry into the wiring storage container.

[0012] Suitablely, the spring element is fastened to the carrier element and / or the wiring harness. Thus, the spring element remains oriented in its axial direction, and the wiring harness slides separately into the wiring harness. If the spring element is fixed to both the carrier element and the wiring harness, an additional advantage is obtained: the carrier element is forced into orientation, for example, after disengagement, due to the spring preload of the spring element. This is particularly advantageous when the carrier element is a wedge-shaped pivot frame, which, due to forced orientation, is in the correct position for re-hooking.

[0013] Advantageously, the spring element is a helical spring, an expandable hose, or a resilient bellows. The helical spring, expandable hose, or bellows can completely enclose the wire harness in the circumferential direction, thereby providing particularly advantageous guidance and protection for the wire harness in all directions.

[0014] The spring element should have an anti-torsion device, or be fixedly installed to prevent torsion about its longitudinal axis. This ensures that the spring element (especially when the spring element is constructed as a helical spring) cannot be rotated out of the fastener by rotation about its longitudinal axis.

[0015] Preferably, the wire harness is placed in the wire memory as a loop. For example, the loop can be constructed as a U-shape, S-shape, Ω-shape, or as a tightened lasso.

[0016] The collar is specifically divided into an entry section and an exit section, and forms a maximum collar angle of 270°, particularly preferably a maximum of 205°, and very particularly preferably 200°, regardless of the orientation of the bearing element. In embodiments where the collar is a tightening sling, a collar angle of 360° to 400° can thus be achieved. The entry section moves out of the line memory during the pivoting movement of the bearing element and pulls the collar together. The exit section is preferably fixed in or on the line memory at its end side. During straight-line travel, most of the entry section moves into the line memory.

[0017] Suitablely, regardless of the relative position of the carrying elements, the ferrules are always oriented in the same direction. Entering and exiting sections typically do not cross in U-shaped, S-shaped, or Ω-shaped ferrules. In the case of a tightened ferrule, the entering and exiting sections cross within the line memory.

[0018] In the straight-line traveling posture of the carrying element, the collar can have the maximum collar length within the line memory. The collar moves backward through the entry section, thereby accommodating a larger section of the wire harness within the line memory.

[0019] During the turning motion of the load-bearing component, the collar can have a minimum collar length within the wiring memory. A portion of the harness is pulled out of the wiring memory on the side entering the section, and the collar changes its orientation in the opposite direction, thereby reducing its radius.

[0020] Significantly, the circuit memory comprises a box-shaped or can-shaped housing, and the wire harness is placed on the bottom wall of the box-shaped or can-shaped housing. During changes in the orientation of the collar, the collar slides on the bottom wall, thereby eliminating the need for moving parts and tensioning elements.

[0021] Advantageously, the spring element is secured to the carrier element using a front guide bracket and / or to the circuit memory using a rear guide bracket. The front and rear guide brackets pivot together with the spring element, thereby reducing the risk of irreversible bending of the spring element.

[0022] The following embodiment is particularly preferred, in which the front and / or rear guide brackets are supported by pivot bearings about a vertical pivot axis in the insertion position. The pivot bearing of the front guide bracket can act on the load-bearing element, and the pivot bearing of the rear guide bracket can act on the housing of the circuit memory.

[0023] According to another design, the outwardly expanding guide elements are arranged on the opposite sides of the front guide bracket and / or the rear guide bracket. In the event of particularly severe outward swing of the load-bearing element, the spring element rests against the inside of the bend of the guide element located there, thereby further reducing the risk of bending of the spring element.

[0024] Advantageously, in the installed position, the guide element protrudes rearward and / or forward relative to the front and / or rear guide bracket, that is, it protrudes in a rearward direction relative to the forward movement of the saddle train. The mutually facing inner sides of the guide elements may be constructed with arches in opposite directions. The arches should extend as continuously as possible to prevent bending of the spring element.

[0025] Preferably, the wiring harness comprises a plurality of supply lines wrapped and / or held together by at least one protective hose. The protective hose protects the supply lines from mechanical damage, especially when the supply lines continuously slide relative to the spring element and housing, for example, on its bottom wall. Embodiments with protective hoses having surfaces that ensure a particularly advantageous coefficient of friction are particularly advantageous. This, in turn, reduces wear and allows the wiring harness to slide into and out of the wiring storage particularly smoothly.

[0026] Suitably, a carrier element connector is provided on the carrier element, and / or a line storage connector is provided on or adjacent to the line storage. Electrical, pneumatic, and possibly hydraulic connections to the supply circuit of the tractor are possible via the carrier element connector. The carrier element connector is typically constructed as a plug, and its complementary component on the tractor is constructed as a socket for safety reasons, as it is conductive. The carrier element connector engages or disengages during each hook-and-unhooking process. The line storage connector typically enables the wiring guidance device to be connected to the onboard network of the saddle trailer via its complementary plug component, and is typically implemented as a socket because it is conductive. In general, the line storage connector is kept separate only for maintenance and repair purposes.

[0027] Advantageously, the load-bearing element is a wedge-shaped pivot frame that can be fastened to the saddle trailer or a plug-in bracket that can be fastened to the trailer. A wiring memory, along with an automated coupling system, is then configured to connect the supply lines of the saddle trailer or trailer to the tractor.

[0028] The invention also extends to the combination of the aforementioned line guidance device with a vehicle constructed as a saddle trailer, wherein the load-bearing element is a wedge-shaped pivoting frame that can pivot about the kingpin.

[0029] Significantly, the wiring storage device is located beneath the trailer bottom of the saddle trailer. This location allows for direct access for installation and maintenance purposes. Furthermore, the wiring storage device and the entire wiring guidance system can be installed without requiring major structural modifications to the saddle trailer.

[0030] The following embodiment is particularly preferred, in which the wiring memory is fastened to the underside of the trailer bottom, to a chassis component, or to an attachment of a saddle trailer, such as a jack. The chassis component is particularly understood to be a longitudinal or lateral load-bearing member of the saddle trailer frame, or an attachment bracket for the jack.

[0031] The harness collar may have an entry section and an exit section for entering the wiring memory, both oriented toward the front of the saddle trailer. The concave side of the collar faces the front of the saddle trailer.

[0032] According to alternative implementations, the vehicle can also be a trailer, and the load-bearing element can be a plug-in bracket movably supported relative to the drawbar. During operation, such as when navigating a curve, the plug-in bracket typically pivots together with a complementary plug-in socket on the tractor side, into which the plug-in bracket inserts. This pivoting movement necessitates guiding the wiring harness on the trailer side, where the harness is pulled further out of the wiring memory in a turning posture compared to a straight-line driving posture. In most cases, the plug-in bracket is pivotally supported relative to the trailer's drawbar.

[0033] Advantageously, the circuit memory is secured to the tow bar of the trailer, or fixedly secured relative to the orientation of the tow bar of the trailer.

[0034] According to yet another embodiment, the vehicle is constructed as an articulated vehicle and has first and second vehicle components that are separated from each other by a rotating hinge. Here, the supporting element is a collection bracket arranged on the first vehicle component, and the wiring memory is preferably fixedly fastened relative to the orientation of the second vehicle component. With the aid of the wiring memory, a connection with the wiring harness to the relatively movable collection bracket of the first vehicle component can be achieved with minimal sagging, regardless of the bending position of the first and second vehicle components relative to each other.

[0048] Figure 1 A side view of a vehicle 10 in the form of a saddle trailer 10a is shown. This saddle trailer can be moved into a tractor unit (not shown further here) by means of a kingpin 15 that protrudes downward relative to the lower side 12 of the trailer bottom 11. Figure 2 and Figure 3 The saddle coupler 16 is schematically shown and can be locked to. The saddle coupler 16 has a V-shaped widened insertion opening 17 at its end facing the saddle trailer 10a during hooking. During further approach of the tractor and the saddle trailer 10a, the kingpin 15 is laterally guided through the insertion opening and finally locked in its final position.

[0049] The kingpin 15 is located in the section adjacent to the front 14 of the saddle trailer 10a. Typically, the trailer bottom 11 is supported by two longitudinal load-bearing members 13a extending along the vehicle's longitudinal axis, which together with other transverse load-bearing members omitted for overview purposes form the chassis component 13.

[0050] The load-bearing element 40, in the form of a wedge-shaped pivot frame 40a, is pivotally supported on the saddle trailer 10a around the kingpin 15, especially during automatic hooking, to establish an electrical and pneumatic connection with the tractor unit via the kingpin. As the kingpin 15 moves into the saddle coupler 16, the wedge-shaped pivot frame 40a also reaches the insertion opening 17 of the saddle coupler 16 and is laterally supported therein due to its complementary shape to the insertion opening 17.

[0051] The wiring harness 20 extends from the wedge-shaped pivot frame 40a in a rearward direction x along the saddle trailer 10a to a wiring storage 50 that is oriented and fixedly fastened to one of the trailer bottom 11 or chassis components 13. The wiring storage 50 accommodates or exposes a portion of the wiring harness 20 depending on the relative positioning of the saddle trailer 10a with respect to the saddle coupler 16, thereby preventing the wiring harness 20 from sagging during straight-line travel.

[0052] The straight-line driving posture of the tractor and the saddle trailer 10a can be Figure 2 As seen in the image, the wedge-shaped pivot frame 40a, wiring harness 20, and wiring memory 50 are substantially aligned along the longitudinal axis of the saddle trailer 10a. In this positioning, the small distance between the wedge-shaped pivot frame 40a and the wiring memory 50 is traversed by the wiring harness 20. Due to its shape stability, the wiring harness 20 is partially compressed into the wiring memory 50 by the wedge-shaped pivot frame 40a. A spring element 21 is arranged between the wedge-shaped pivot frame 40a and the wiring memory 50, wrapping around the wiring harness 20 over the entire distance. The spring element 21 has its shortest axial length between the wedge-shaped pivot frame 40a and the wiring memory 50.

[0053] Figure 3 The extreme cornering posture is shown, which occurs, for example, especially during dispatch. The wedge-shaped pivot frame 40a swings outward counterclockwise by approximately 90°, pulling a portion of the wiring harness 20 out of the wiring memory 50. The wiring memory 50 thus prevents the wiring harness 20 from being pulled off the wedge-shaped pivot frame 40a. Based on the pivoting path completed by the wedge-shaped pivot frame 40a, the spring element 21 extends its axial length accordingly. However, the movement of the wiring harness 20 does not depend on the extension of the spring element 21 because they are not interconnected. The wiring harness 20 rests on the spring element 21 solely by its own weight, but is not kinematically coupled to the spring element 21.

[0054] exist Figure 4In the straight-line driving posture, the wedge-shaped pivot frame 40a is oriented. In the hook-up state between the saddle trailer and the tractor, the wedge-shaped pivot frame connector 41 connects to the complementary connector of the tractor, thereby establishing at least one electrical and pneumatic connection. The wedge-shaped pivot frame connector 41 is electrically connected to the wiring harness 20, which includes a total of six supply lines 23a, 23b, 23c, 23d, 23e, and 23f, of which four supply lines 23a, 23b, 23c, and 23d are electrical lines, and two supply lines 23e and 23f are pneumatic lines. Multiple supply lines 23a, 23b, 23c, 23d, 23e, and 23f are always installed together in a protective hose 24. In addition to providing mechanical protection for the supply lines 23a, 23b, 23c, 23d, 23e, and 23f, the protective hose has a particularly smooth surface that reduces sliding friction between the wire harness 20 and the spring element 21 surrounding it.

[0055] In the illustrated embodiment, the spring element 21 is a cylindrical helical spring, with its end section secured to both the wedge-shaped pivot frame 40a and the wiring harness 50. In a straight-line driving posture, the spring element 21 is in a compressed, short position. The wiring harness 20 extends loosely through the internal space of the spring element 21 and rests against it only with its underside under gravitational load. The wiring harness 20 is secured to the wedge-shaped pivot frame 40a by means of a traction relief mechanism 42, so that the traction force on the wiring harness 20 is directed away from the permanent connection to the wedge-shaped pivot frame insertion element 41.

[0056] As in Figure 4 and Figure 5 As can be seen particularly well, the line memory 50 includes a box-shaped housing 51 having a bottom wall 52 and side walls 53 extending upward therefrom, the side walls being in accordance with... Figure 1 The installed positioning rests against the trailer bottom 11 or chassis component 13 on the end side. The spring element 21 is centrally secured to the side wall 53 of the housing 51 facing the wedge-shaped pivot frame 40a, and the wiring harness 20 passes through an opening 55 formed in the side wall 53 via its entry section 25 (see...). Figure 5 The wire harness 20 enters the housing 51. To ensure particularly stable entry and exit of the wire storage 50, a support roller 56 is rotatably supported laterally offset inside the housing 51 and adjacent to the opening 55. The support roller ensures smooth movement of the entry section 55, especially during the pull-out movement of the entry section 55.

[0057] Within the housing 51 of the line memory 50, the wire harness 20 is stored in a single loop 22 in the plane, specifically on the bottom wall 52 of the housing 51.

[0058] In the straight-line driving posture of the wedge-shaped pivot frame 40a, the collar 22 has a maximum length l max The exit section 26 of the wiring harness 20 is connected to the wiring memory connector 54, through which the wiring memory 50 can be connected to the onboard network of the saddle trailer 10a. The wiring memory connector 54 is also housed in the side wall 53 of the housing 51 facing the wedge-shaped pivot frame 40a. In a straight-line driving posture, the entry section 25 and the exit section 26 are located on the opposite side of the bottom wall 52 adjacent to its nearest side wall 53.

[0059] Figure 6 The diagram illustrates the pulling of the wiring harness 20 from the wiring memory 50 in a turning driving posture, wherein the loop 22 moves to the left in the image plane toward the sidewall 53 facing the wedge-shaped pivot frame 40a. The radius and length of the loop 22 are reduced, and the length now has a minimum loop length l. min .

[0060] Figure 7 A longitudinal sectional view of the wire harness 20 and the spring element 21 surrounding the wire harness is shown. The spring element 21 is fastened to the wedge-shaped pivot frame 40a by means of a front guide bracket 30 and to the housing 51 of the circuit memory 50 by means of a rear guide bracket 31. The front guide bracket 30 and the rear guide bracket 31 are implemented in the same manner. The front guide bracket 30 and the rear guide bracket 31 are each supported by a pivot bearing 32 about a vertical pivot axis Z (see [reference]). Figure 8 The pivot bearing 32 of the front guide bracket 30 acts on the wedge-shaped pivot frame 40a. The rear guide bracket 31 is placed into the opening 55 of the housing 51 of the line memory 50 and is supported relative to the housing 51 by means of its respective pivot bearing 32.

[0061] Furthermore, guide elements 34 are constructed on the opposing sides 33 of the front and rear guide brackets 30, 31. These guide elements are laterally and outwardly swung in the rearward direction x and protrude relative to the guide brackets 30, 31. In the top view, each guide element 34 or its inner side 35 of the front or rear guide brackets 30, 31 achieves an arc of approximately 90° in opposite directions. Moreover, opposite to the rearward direction x, pairs of laterally and outwardly swung guide elements 34 are provided on the front and rear guide brackets 30, 31.

[0062] In the straight-line driving posture of the wedge-shaped pivot frame 40a, the guide element 34 is spaced apart from the spring element 21 and therefore does not function. However, once a turning driving posture occurs, the wedge-shaped pivot frame 40a moves laterally outward relative to the line memory 50, and the spring element 21 bears irreversible bending loads in the region of the wedge-shaped pivot frame 40a or in the region of the opening 55 of the housing 51. The guide brackets 30, 31 at the front and rear rotate first with the fasteners of the spring element 21. In the more limited turning driving posture, the spring element 21 rests against the inner side 35 of the bend of the corresponding guide element 34, thereby largely avoiding bending loads.

[0063] Figure 8 An enlarged perspective view of the front or rear guide brackets 30, 31 is shown, and Figure 9 An exemplary fastening of the spring element 21 by means of a spring element fastening mechanism 36 is shown. The spring element fastening mechanism 36 includes a clamp opening 36b constructed in the opposing side 33 of the front or rear guide brackets 30, 31, through which a U-shaped clamp 36a is inserted, and is secured in particular by a retaining pin 36c to prevent loss. The clamp 36a may be positioned, for example, first passing through the coil of the spring element 21 from the inside and then through the clamp opening 36b. The associated retaining pin 36c passes through the free side of the clamp 36a outside the front or rear guide brackets 30, 31.

[0064] It is also possible that the two ends of the clamp 36a are threaded, and the nuts are screwed onto the threads instead of the retaining pins 36, and the clamp 36a is pre-tightened in this way, so that the spring element 21 presses against the front or rear guide brackets 30, 31 from the inside and is held there in a clamping manner.

[0065] exist Figure 10 In the perspective view, the housing 51 of the wiring memory 50 can be seen. In the side wall 53 facing the wedge-shaped pivot frame 40a, the opening 50 is located in the middle, and the rear guide bracket 31 is placed into this opening. The wiring harness 20 enters the wiring memory 50 through this rear guide bracket. Directly laterally, next to the opening 50 and the rear guide bracket 31, a wiring memory connector 54 is placed in the same side wall 53, allowing the wiring memory 50 to be connected to the onboard network of the saddle trailer 10a.

[0066] Figure 11The front end of a vehicle 10 in the form of a trailer 10b is shown, which can be hooked to a tractor unit (not shown) via a drawbar 18. A load-bearing element 40, as a plug-in bracket 40b, is arranged above the drawbar 18. This plug-in bracket inserts into a complementary-shaped plug-in socket of the tractor unit to establish an electrical and pneumatic connection. The plug-in bracket 40b can pivot relative to the drawbar 18 about its vertical axis so that it can pivot together with the plug-in socket of the tractor unit during cornering and ensures a continuous connection between the plug-in bracket 40b and the plug-in socket on the tractor unit side.

[0067] The orientation change of the connector bracket 40b relative to the pull rod 18 is compensated by a wiring memory 50 fixedly mounted on the pull rod 18, and the wiring harness 20 acting on the connector bracket 40b extends into the wiring memory. The wiring memory 50 structurally corresponds to... Figures 1 to 10 The structural implementation plan described in the document.

[0068] In this embodiment, the wiring harness 20 is also completely surrounded in the peripheral direction by the spring element 21, which is secured both to the connector bracket 40b and to the wiring memory 50. With the aid of the spring element 21, the wiring harness 20 is guided in the axial direction, allowing it to be drawn out of the wiring memory 50 during cornering and returned to the wiring memory 50 during straight-line driving due to its bending strength. Figure 11 In the illustration, the carrier element 10 in the form of a plug-in bracket 40b is in a straight-line driving posture, in which the spring element 21 is contracted and the maximum section of the wiring harness 20 is accommodated by the line memory 50.

[0069] In another embodiment, Figure 12 The installation of a line guiding device on a vehicle 10 or its frame member in the form of an articulated vehicle 10c is shown. The articulated vehicle 10c has a first vehicle component 10c1 and a second vehicle component 10c2, which are connected to each other by a pivot hinge 19 arranged between them. The articulated vehicle 10c... Figure 12 The diagram shows the vehicle in a turning posture, in which the first vehicle component 10c1 is bent relative to the second vehicle component 10c2 at the rotation hinge.

[0070] The wiring harness 20 extends from the first vehicle component 10c1 to the second vehicle component 10c2 via the pivot hinge 19. Because the relative positions of the first and second vehicle components 10c1 and 10c2 change continuously during operation, the wiring harness 20 needs to be matched to the corresponding flexural postures of the first and second vehicle components 10c1 and 10c2. This matching is achieved by means of a wiring memory 50. The wiring harness 20 is secured to a carrier element 40 in the form of a collection bracket 40c, positioned on one side of the outer periphery of the pivot hinge 19 and extending from there into the wiring memory 50. Throughout its extension from the wiring memory 50 to the collection bracket 40c, the wiring harness 20 is received and loosely stored therein by a spring element 21. Due to the flexural postures of the first and second vehicle components 10c1 and 10c2, the spring element 21 is in an extended posture, which is released during the return to a straight-line driving posture.

[0071] In this embodiment, the wire harness also exits and enters the wire storage segmentally, kinematically independent of the spring element 21, solely due to its bending strength, while the spring element merely supports the wire harness 21 and prevents it from sagging.
