The invention was based on the problem of providing a cable routing device of compact design suitable for ensuring low sagging of a line strand (20) having a large diameter.

Description

[Technical Field]

[0001] The present invention relates to a cable routing device for connecting a line strand to a carrier element movable relative to a vehicle according to the features of the preamble of claim 1. Furthermore, the invention is also implemented in combination with a semi-trailer, trailer or articulated vehicle. [Background technology]

[0002] A semitrailer typically consists of a towing vehicle and a semitrailer, which are releasably connected to each other by a fifth-wheel coupling located on the towing vehicle and a kingpin attached to the semitrailer. This allows the semitrailer to be parked and another semitrailer to be picked up instead. To perform this coupling process, the driver must usually exit and mechanically release the fifth-wheel coupling to uncouple the vehicle, or after coupling, check the locking status of the kingpin, which is properly inserted into the fifth-wheel coupling.

[0003] A combination truck and trailer assembly typically consists of a towing vehicle and a trailer coupled to the towing vehicle, the trailer being releasably attached to the trailer hitch of the towing vehicle by a drawbar.

[0004] An articulated vehicle is, for example, an articulated bus used in local public transportation. An articulated vehicle may also be, for example, a wheel loader, a road roller, or an articulated dump truck. Articulated vehicles have in common that they are designed from first and second vehicle components connected with a swivel joint between them. The first and second vehicle components cannot be separated from each other during operation. When the articulated vehicle turns, the first and second vehicle components change their relative positions with respect to each other.

[0005] Previous efforts have been made to automate the process of coupling and uncoupling a semitrailer to a towing vehicle and establishing a connection between the supply lines. For example, DE10 2004 024 333 A1 discloses a plug-in coupling system in which a wedge pivot frame pivotally mounted on a kingpin is inserted into the inlet opening of the fifth wheel coupling during coupling between the semitrailer and the towing vehicle and is retained there after the kingpin is locked. Because the wedge swivel frame pivots relative to the semitrailer while the semitrailer is turning a curve, the supply lines must be dimensioned accordingly long to avoid breaking when turning a sharp curve. However, when driving in a straight line, the supply lines may sag and become damaged.

[0006] For this reason, DE 10 2004 044 992 A1 proposes to mount a line storage device on a semi-trailer, in which the supply lines emerging from a wedge swivel frame are wound around a spring-loaded drum disc and are unwound under tension when going around a bend. The main disadvantages of this known line storage are the relatively large installation space required and the problem of having to accommodate line strands with an ever-increasing number of supply lines on the drum disc without going below the minimum permissible bending radius provided for the line strand. Summary of the Invention

[0007] The invention was based on the object of providing a cable routing device of compact design suitable for ensuring low sag of line strands with large diameters.

[0008] This object is achieved according to the invention with the features of claim 1. A spring element is understood to be a component that is reversible under the expected operating load and can be stretched in its axial range between a maximum and a minimum length. The spring element can, in principle, be made of spring steel, plastic, or a rubber mixture. Essentially, the line strand is always loosely arranged in, on, or above the spring element and is not otherwise connected to it.

[0009] The term "loose" refers to the mechanical separation of the spring element and the line strand. As a result, the spring element can be lengthened or shortened independently of the line strand. Relative movement with respect to the spring element can occur in the axial direction of the line strand. The line strand is supported by the spring element and only needs to overcome the sliding friction resulting from its weight for axial movement. In the radial direction, the line strand is guided through the spring element with a small amount of movement.

[0010] While going around a curve, the carrier element changes its relative position with respect to the cable store, so that the distance between the carrier element and the cable store increases, and the line strand has to bridge this longer distance. In this situation, the part of the line strand located in the cable store is pulled out of the cable store by the carrier element. When the vehicle goes straight again, the distance between the carrier element and the cable store decreases, so that the line strand has to bridge a shorter distance. In this situation, the line strand is partially pushed back into the cable store by the carrier element.

[0011] On the one hand, the spring elements ensure that the line strand is always supported and does not sag downwards and therefore cannot collide with other vehicle parts.

[0012] As the line strand moves into the cable enclosure, the spring element prevents the line strand from moving laterally and ensures smooth entry into the cable enclosure.

[0013] The spring element is advantageously attached to the carrier element and / or the cable storage, so that the spring element is held stationary in its axial direction, while the line strand is separated from the spring element and slides into the cable storage. If the spring element is fixed to both the carrier element and the cable storage, this has the additional advantage that, for example, after separation, the spring preload of the spring element forces the carrier element to align. In particular, if the carrier element is a wedge swivel frame, this forced alignment ensures that it is in the correct position for a new connection.

[0014] The spring element is advantageously a coil spring, an expandable hose or an elastic bellows, which can completely surround the wire strand in the circumferential direction, so that the wire strand is particularly well guided and protected in all directions.

[0015] The spring element should have an anti-twist device or be installed so that it is fixed against rotation about its longitudinal axis, which ensures that the spring element cannot rotate out of the fastener by rotating about its longitudinal axis, especially if the spring element is designed as a coil spring.

[0016] The line strand is preferably inserted into the cable housing as a loop. The loop can be designed, for example, to have a U-shape, an S-shape, an Ω-shape or as a tightening loop.

[0017] The loop is preferably tensioned by the inlet section and the outlet section and encloses a maximum loop angle of 270°, particularly preferably a maximum of 205°, and very particularly preferably 200°, regardless of the position of the carrier element. In one embodiment of the loop as a tightening loop, a loop angle of 360° to 400° can be achieved. When the carrier element pivots and pulls the loop together, the inlet section exits the cable enclosure. The outlet section is preferably fixed at its end in or on the cable enclosure. During straight-ahead driving, the inlet section moves primarily into the cable enclosure.

[0018] Advantageously, the direction of the loop is always the same regardless of the relative positions of the carrier elements. The entry and delivery sections typically do not cross each other in a U-shaped, S-shaped, or Ω-shaped loop. In a tightening loop, the entry and delivery sections cross each other within the cable enclosure.

[0019] In the straight position of the carrier element, the loop in the cable enclosure can have a maximum loop length, and the loop is pushed rearward through the entry section, thereby accommodating a larger portion of the line strand in the cable enclosure.

[0020] However, in the cornering position of the carrier element, the loop can have a minimum loop length within the cable store. As part of the line strand is pulled out of the cable store by the entry section, the loop changes its position in the opposite direction, thereby reducing its radius.

[0021] The cable store advantageously comprises a box- or cup-shaped housing, the line strand being arranged on a bottom wall of the box- or cup-shaped housing. When the loop changes position, it slides on the bottom wall, which means that moving parts and tension elements are no longer required.

[0022] Advantageously, the spring elements are attached to the carrier element by means of a forward guidance console and / or to the cable store by means of a rear guidance console, which pivot together with the spring elements, thereby reducing the risk of irreversible twisting in the spring elements.

[0023] In a particularly preferred embodiment, the front and / or rear guidance consoles are mounted by pivot bearings about a vertical pivot axis in the installation position, the pivot bearing of the front guidance console being able to engage in particular with the carrier element and the pivot bearing of the rear guidance console being able to engage with the housing of the cable storage compartment.

[0024] According to a further embodiment, outwardly branching guide elements are arranged on both sides of the front and / or rear guidance consoles. In the event of particularly strong swinging of the carrier element, the spring elements abut on the inside of the bend against the guide elements arranged there, which further reduces the risk of twisting of the spring elements.

[0025] Advantageously, in the installed position, the guide elements project rearward and / or forward relative to the front and / or rear guidance consoles, i.e., in the rearward direction relative to the forward movement of the tractor-trailer. Opposite inner sides of the guide elements can be designed with opposite curvatures. The curvature should be as continuous as possible to prevent twisting of the spring elements.

[0026] The line strand preferably comprises a plurality of supply lines that are covered 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 are constantly sliding against the spring element and the housing, for example on their bottom wall. It is particularly advantageous to design the protective hose with a surface that ensures a particularly favorable coefficient of friction. This reduces wear and allows for particularly uniform sliding movement of the line strand in and out of the cable storage.

[0027] The carrier element plug element is conveniently provided on the carrier element and / or on or adjacent to the cable storage plug element. With the help of the carrier element-plug element, electrical, pneumatic, and, if necessary, hydraulic connection to the towing vehicle's supply circuit is possible. The carrier element plug element is often designed as a plug, and the complementary component of the towing vehicle is designed as a socket for safety reasons, since it is live. The carrier element plug element is connected or released during each coupling and uncoupling process. The cable storage plug element allows the cable routing device to be connected to the semitrailer's on-board electrical system, typically via a complementary plug component of the semitrailer, and is usually designed as a socket, since it carries electrical current. The cable storage plug element is usually only removed for repair and maintenance purposes.

[0028] Advantageously, the carrier element is a wedge pivot frame that can be attached to a semi-trailer or a plug console that can be attached to a trailer, in which case the cable storage is provided with an automatic coupling system for connecting the supply lines of the semi-trailer or trailer to the towing vehicle.

[0029] The invention also extends to the combination of the cable routing device described above with a vehicle designed as a semi-trailer, the carrier element being a wedge pivot frame that can pivot about a kingpin.

[0030] The cable enclosure is preferably located under the trailer floor of the semi-trailer. This mounting location allows direct access for assembly and repair purposes. Furthermore, the cable enclosure and the entire cable routing device can be installed without requiring major structural modifications to the semi-trailer.

[0031] In a particularly preferred embodiment, the cable storage is mounted on the underside of the trailer floor or on a chassis part or on an attachment of the semi-trailer, such as a support jack, where chassis part is understood to mean in particular a longitudinal or cross member of the vehicle frame of the semi-trailer or a mounting bracket for a support jack.

[0032] The loop of line strand can have a section that enters the cable storage compartment and a section that exits, both of which are aligned toward the front of the semi-trailer, with the concave side of the loop facing the front of the semi-trailer.

[0033] According to an alternative embodiment, the vehicle may be a trailer and the carrier element may be a connector console movably mounted on the towbar. The connector console regularly pivots when driving, for example when negotiating a curve, and a complementary shaped plug socket is provided on the towing vehicle side and inserted therein. This pivoting movement requires that the line strand be carried by the trailer, and the line strand is pulled further out of the cable storage compartment in a cornering position than in a straight-ahead position. In most cases, the connector console is pivotally attached to the trailer's towbar.

[0034] Conveniently, the cable house is fixedly attached to or mounted on the trailer drawbar.

[0035] According to yet another embodiment, the vehicle is designed as an articulated vehicle and has first and second vehicle components separated from each other by a swivel joint. The carrier element is a collection console arranged on the first vehicle component, and the cable enclosure is preferably fixed in place on the second vehicle component. With the help of the cable enclosure, a nearly slack-free connection of the line strands to the relatively movable collection console of the first vehicle component can be achieved, regardless of the bending position of the first and second vehicle components relative to each other.

DETAILED DESCRIPTION OF THE INVENTION

[0038] 1 shows a side view of a vehicle 10 in the form of a semi-trailer 10a, which can be driven into and locked to a fifth wheel coupling 16, shown diagrammatically in FIGS. 2 and 3, of a towing vehicle (not shown here) by means of a kingpin 15 projecting downwards relative to the bottom 12 of the semi-trailer floor 11. At its end facing the semi-trailer 10a during coupling, the fifth wheel coupling 16 has a V-shaped widening entrance opening 17, through which the kingpin 15 is guided laterally as the towing vehicle and the semi-trailer 10a move closer together until it is finally locked in its end position.

[0039] The kingpin 15 is located adjacent the front 14 of the semi-trailer 10a. Typically, the trailer floor 11 is supported by two longitudinal beams 13a extending along the longitudinal axis of the vehicle, which together with a further cross beam, omitted for clarity, form a chassis component 13.

[0040] A carrier element 40 in the form of a wedge pivot frame 40a is mounted to the semi-trailer 10a so as to be pivotable about the kingpin 15, and electrical and pneumatic connections to the towing vehicle are established via the wedge pivot frame 40a, in particular during the automatic coupling process.

[0041] As the kingpin 15 retracts into the fifth wheel coupling 16, the wedge pivot frame 40a also enters the inlet opening 17 of the fifth wheel coupling 16 and is laterally supported therein due to its complementary shape to the inlet opening 17.

[0042] From the wedge pivot frame 40a, the line strand 20 extends in the rearward direction x of the semi-trailer 10a to a cable store 50 fixed to the trailer floor 11 or one of the chassis parts 13. Depending on the relative position of the semi-trailer 10a to the fifth wheel coupling 16, the cable store 50 either takes up a portion of the line strand 20 or releases a portion of the line strand 20, thereby preventing the line strand 20 from slackening during straight-ahead driving.

[0043] The straight-ahead position of the towing vehicle and semitrailer 10a can be seen in FIG. 2. The wedge pivot frame 40a, line strand 20, and cable enclosure 50 are essentially aligned with the vehicle's longitudinal axis. In this position, the line strand 20 must bridge a relatively short distance between the wedge pivot frame 40a and the cable enclosure 50. Due to its rigidity, the line strand 20 is partially pressed into the cable enclosure 50 by the wedge pivot frame 40a. A spring element 21 is positioned between the wedge pivot frame 40a and the cable enclosure 50, which accommodates the line strand 20 over the entire distance. The spring element 21 has its shortest axial length between the wedge pivot frame 40a and the line strand 50.

[0044] Figure 3 shows an extreme cornering position, particularly one that may occur during maneuvering. The wedge pivot frame 40a has rotated approximately 90° counterclockwise, pulling a portion of the line strand 20 out of the cable housing 50. This prevents the line strand 20 from being torn off from the wedge pivot frame 40a. The spring element 21 has correspondingly extended its axial length due to the pivot path traversed by the wedge pivot frame 40a. However, the movement of the line strand 20 occurs independently of the extension of the spring element 21, since they are not connected to each other. The line strand 20 rests on the spring element 21 only by its weight and is not otherwise kinematically coupled to the spring element 21.

[0045] In Figure 4, the wedge pivot frame 40a is aligned in a straight-forward position. When the semi-trailer is coupled to the towing vehicle, the wedge pivot frame plug element 41 connects to a complementary plug element on the towing vehicle, thereby establishing at least one electrical and pneumatic connection. The wedge pivot frame plug element 41 is electrically connected to the line strand 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. A number of supply lines 23a, 23b, 23c, 23d, 23e, 23f are always inserted together into a protective hose 24 which, in addition to providing mechanical protection for the supply lines 23a, 23b, 23c, 23d, 23e, 23f, also has a particularly smooth surface which reduces sliding friction between the line strand 20 and the spring element 21 surrounding the line strand 20.

[0046] In the exemplary embodiment shown, the spring element 21 is a cylindrical coil spring whose end sections are fixed to both the wedge pivot frame 40a and the cable store 50. In the straight-ahead position, the spring element 21 is in a contracted, short position. The line strand 20 extends loosely through the interior of the spring element 21, resting only with its lower surface on the spring element 21 under gravity. The line strand 20 is attached to the wedge pivot frame 40a using a strain relief 42 to direct tension in the line strand 20 away from its permanent connection to the wedge pivot frame plug element 41.

[0047] As can be seen particularly clearly in Figures 4 and 5, the cable storage compartment 50 comprises a box-shaped housing 51 having a bottom wall 52 and side walls 53 projecting thereover, which, in the assembled position according to Figure 1, rests against the trailer floor 11 or the front of the chassis part 13. The spring element 21 is fixed centrally to the side wall 53 of the housing 51 facing the wedge pivot frame 40a, and the line strand 20 enters the housing 51 at its entry section 25 through an opening 55 (see Figure 5) formed in the side wall 53. For a particularly smooth entry and exit of the line strand 20 into and from the cable storage compartment 50, a support roller 56 is rotatably mounted in the housing 51 adjacent to and laterally offset from the opening 55, which ensures a uniform movement of the line strand 20, especially when exiting the entry section 55.

[0048] Within the housing 51 of the cable enclosure 50, the line strand 20 is housed in one plane, in particular in a single loop 22 on the bottom wall 52 of the housing 51.

[0049] In the straight-ahead position of the wedge pivot frame 40a, the loop 22 has a maximum length lmax. The outflow section 26 of the line strand 20 is connected to a cable storage plug element 54, through which the cable storage section 50 is connected to the on-board electrical system of the semi-trailer 10a. The cable storage plug element 54 is also inserted into the side wall 53 of the housing 51 facing the wedge pivot frame 40a. In the straight-ahead position, the inflow section 25 and the outflow section 26 are located on either side of the bottom wall 52, adjacent to the side wall 53 nearest to them.

[0050] 6 illustrates the situation of the line strand 20 being pulled out of the cable storage 50 in a cornering position, with the loop 22 moving to the left in the image plane, towards the side wall 53 facing the wedge pivot frame 40a. The radius of the loop 22 decreases, as does its length, until it reaches the minimum loop length lmin.

[0051] 7 shows a cross-sectional view of the line strand 20 surrounded by the spring element 21. The spring element 21 is attached to the wedge pivot frame 40a by the forward guidance console 30 and to the housing 51 of the cable store 50 by the rear guidance console 31. The forward guidance console 30 is designed identically to the rear guidance console 31. The front and rear guidance consoles 30, 31 are each mounted around a vertical pivot axis z using pivot bearings 32 (see FIG. 8). The pivot bearings 32 of the forward guidance console 30 engage with the wedge pivot frame 40a. The rear guidance console 31 is inserted into an opening 55 in the housing 51 of the cable store 50 and is attached to the housing 51 by the associated pivot bearings 32.

[0052] Additionally, guide elements 34 are formed on opposing sides 33 of the forward and rear guidance consoles 30, 31, which curve outward in the lateral and rearward direction x and protrude relative to the forward and rear guidance consoles 30, 31. In plan view, each guide element 34 of the front or rear guidance console 30, 31 or its inner side 35 completes an arc of approximately 90° and faces each other in opposite directions. Pairs of lateral and outward curved guide elements 34 are also provided on the forward and rear guidance consoles 30, 31 opposite the rearward direction x.

[0053] In the straight-ahead position of the wedge pivot frame 40a, the guide elements 34 are located at a distance from the spring elements 21 and therefore have no function. However, as soon as a cornering position occurs, the wedge pivot frame 40a moves laterally outward relative to the cable storage 50, and the spring elements 21 are subjected to irreversible buckling loads in the area of ​​the wedge pivot frame 40a or in the area of ​​the opening 55 in the housing 51. With the help of the front and rear guidance consoles 30, 31, this initially rotates together with the mounting of the spring elements 21. In an even tighter cornering position, the spring elements 21 come into contact with the inside surface 35 of the respective guide element 34 on the inside of the curve, which largely avoids buckling loads.

[0054] FIG. 8 shows an enlarged perspective view of the front or rear guidance bracket 30, 31, and FIG. 9 shows an exemplary attachment thereof to the spring element 21 by a spring element fastener 36. The spring element fastener 36 includes a bracket opening 36b formed in the opposing side 33 of the front or rear guidance bracket 30, 31, through which a U-shaped bracket 36a is inserted and secured against loss, particularly by a safety pin 36c. The bracket 36a can be inserted, for example, from the inside, first through the windings of the spring element 21 and then through the bracket opening 36b. A corresponding safety pin 36c passes through the free leg of the bracket 36a on the outside of the front or rear guidance console 30, 31.

[0055] Instead of using the safety pin 36c, it is also possible to provide threads on both ends of the bracket 36a and thread nuts onto these threads, thus pretensioning the bracket 36a. This causes the spring element 21 to be pressed from the inside against the wall of the front or rear guidance console 30, 31 and to be held there in a clamped manner.

[0056] 10, the housing 51 of the cable storage compartment 50 can be seen in perspective view. The side wall 53 facing the wedge pivot frame 40a has a central opening 55 into which the rear guidance console 31 is inserted and through which the line strand 20 enters the cable storage compartment 50. Directly to the side of the opening 55 and adjacent to the rear guidance console 31, a cable storage plug member 54 is inserted into the same side wall 53, with the help of which the cable storage compartment 50 can be connected to the on-board electrical system of the semi-trailer 10a.

[0057] 11 shows the front end of the vehicle 10 in the form of a trailer 10b, which can be coupled to a towing vehicle (not shown here) by means of a towbar 18. At the top of the towbar 18 is arranged a carrier element 40 in the form of a connector console 40b which is inserted into a complementary shaped plug socket on the towing vehicle to establish an electrical and pneumatic connection. The connector console 40b can pivot relative to the towbar 18 about its vertical axis so as to be able to pivot together with the towing vehicle's plug socket when cornering and to ensure a constant connection of the connector console 40b to the towing vehicle's plug socket.

[0058] Changes in the position of the connector console 40b relative to the towbar 18 are compensated for by a fixed cable enclosure 50 attached to the towbar 18, and the line strands 20 that engage the connector console 40b extend into the fixed cable enclosure 50. The cable enclosure 50 structurally corresponds to the design described in Figures 1 to 10.

[0059] In this embodiment too, the line strand 20 is completely surrounded in the circumferential direction by a spring element 21 attached both to the connector console 40b and to the cable housing 50. With the help of the spring element 21, the line strand 20 is guided axially and can escape from the cable housing 50 when cornering, and its bending stiffness allows it to be pushed back into the cable housing 50 when driving straight. In the illustration of Figure 11, the carrier element 40 in the form of the connector console 40b is in a straight position, in which the spring element 21 is compressed and the largest section of the line strand 20 is accommodated by the cable housing 50.

[0060] 12 shows the attachment of a cable routing device to a vehicle 10 in the form of an articulated vehicle 10c or to a frame component thereof in a further exemplary embodiment. The articulated vehicle 10c has a first vehicle part 10c1 and a second vehicle part 10c2, which are connected to each other via a swivel joint 19 disposed therebetween. In the view according to FIG. 12, the articulated vehicle 10c is in a cornering position in which the first vehicle part 10c1 is angled towards the second vehicle part 10c2 at the swivel joint 19.

[0061] The line strand 20 extends from the first vehicle part 10c1 to the second vehicle part 10c2 via the swivel joint 19. Since the relative positions of the first and second vehicle parts 10c1, 10c2 constantly change during operation, it is also necessary to adapt the line strand 20 to the respective bending positions of the first and second vehicle parts 10c1, 10c2. This adjustment is performed by the cable housing 50. The line strand 20 is attached to a carrier element 40 in the form of a collecting console 40c, which is arranged on one side of the outer periphery of the swivel joint 19 and extends from there into the cable housing 50.

[0062] The line strand 20 is held by the spring element 21 along the entire path from the cable storage 50 to the collecting console 40c, where it is loosely stored. Due to the bent position of the first and second vehicle parts 10c1, 10c2, the spring element 21 is in an extended position, which is released when returning to the straight forward position.

[0063] In this embodiment too, due to its bending stiffness, the line strand 20 passes partially out of the cable storage section 50 and into the cable storage section 50 and is kinematically isolated from the spring element 21, which only supports the line strand 20 and prevents it from sagging.
