Description

Technical Field

[0001] The present invention relates to a plug-in coupling system, particularly a plug-in coupling system for a traction seat coupling, and a traction seat coupling including the plug-in coupling system. Background Technology

[0002] Plug-in couplers are known in the prior art. They are used to transfer energy or information between a tractor and a towed vehicle, wherein the energy or information transfer connection is automatically established after or during the coupling process. However, a problem with the devices known in the prior art is that the connection of plug-in coupling systems is easily lost, especially unintentionally. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide a device that can ensure an automatic energy transfer or information transfer connection between a tractor and a trailer and prevent the unintentional loss of the connection.

[0004] This objective is achieved by the plug-in coupling system of the present invention and the traction seat coupling device of the present invention (German: Sattelkupplungsanordnung, which can also be translated as fifth wheel device or fifth wheel coupling device).

[0005] According to the present invention, a plug-in coupling system is provided, particularly for a tow seat coupling in commercial vehicles. Advantageously, the plug-in coupling system includes a main coupling device and a secondary coupling device, wherein the main coupling device includes a plug bracket (Steckerkonsole) with a transmission contact portion, wherein the transmission contact portion points particularly in the insertion direction, wherein the secondary coupling device has a connecting bracket (dungskonsole), wherein the plug-in coupling system has a locking device, wherein the plug bracket and the connecting bracket are connected to each other in the coupling position, allowing direct or indirect transmission of information and / or energy between the plug bracket and the connecting bracket, wherein the plug-in coupling system is designed to allow the plug bracket and the connecting bracket to move to a disengaged position, wherein in the disengaged position, direct or indirect transmission of information and / or energy between the plug bracket and the connecting bracket is not possible, wherein the locking device is designed to prevent transfer from the coupling position to the disengaged position in a form-fitting manner in the locked position, and to allow transfer from the coupling position to the disengaged position in the released position. The plug-in coupling system according to the present invention is used in a tow seat coupling in a commercial vehicle. The primary task of a plug-in coupling system is to transfer information and / or energy between the tractor (with a towing seat coupling plate disposed on it) and the towed (with a kingpin disposed on it). Specifically, the plug-in coupling system is designed to establish an energy transfer or information transfer connection between the tractor and the towed without user intervention. In other words, the plug-in coupling system can be an automatic plug-in coupling system. In an exemplary embodiment, the plug-in coupling system can be designed without a drive, allowing an information and / or energy connection between the plug-in bracket and the coupling bracket to be established solely through proximity movement during the coupling process between the tractor and the towed. Alternatively or additionally, preferably, the plug-in coupling system can also be designed to establish an energy or information connection only after the coupling process, for example, via a drive. The plug-in coupling system (particularly the main coupling device and / or the auxiliary coupling device) may include a drive, particularly a coupling drive. Specifically, the plug-in coupling system includes a main coupling device and an auxiliary coupling device. The main coupling device is designed and configured to be disposed on the tractor or the towed. On the other hand, the secondary coupling device is designed and configured to be arranged on the opposing commercial vehicle coupling pair, and thus on the towed or tractor vehicle. In other words, the primary coupling device is arranged on one vehicle, and the secondary coupling device is arranged on another vehicle. The primary coupling device includes a plug bracket with transmission contacts. This plug bracket is designed and configured to engage with the connection bracket of the secondary coupling device, enabling the transmission of information and / or energy between the plug bracket and the connection bracket when the plug-in coupling system is in the coupled position.Therefore, specifically, the plug bracket has transmission contacts, which can be, for example, electrical wiring contacts, hydraulic wiring connections, and / or pneumatic wiring connections. These transmission contacts of the plug bracket are specifically oriented in the insertion direction. This insertion direction is particularly the direction of movement in which the main coupling device must move relative to the secondary coupling device to establish an energy conduction connection and / or information conduction connection between the plug bracket and the connecting bracket. Particularly preferred is that the insertion direction is arranged or oriented parallel to the retraction direction of the towing seat connecting plate. Specifically, in the coupling position, the insertion direction is parallel to the direction of movement in which the kingpin must move relative to the towing seat connecting plate to securely anchor or engage with it. Alternatively or additionally, the insertion direction may preferably be oriented parallel to the straight-line direction of travel of the commercial vehicle on which the plug-in coupling system is arranged. In the coupling position of the plug-in coupling system, information and / or energy can be transmitted directly and / or indirectly between the plug bracket and the connecting bracket. However, if the plug-in coupling system is in the disengaged position, information and / or energy transfer is particularly impossible between the plug holder and the connecting holder. Advantageously, the transfer from the connected position to the disengaged position requires movement in the insertion direction between the plug holder and the connecting holder, specifically by means of an actuator. In other words, this may mean that the transfer from the connected position to the disengaged position requires relative movement of the plug holder relative to the connecting holder in the insertion direction. To prevent the plug-in coupling system from unintentionally escaping the connected position, and particularly to prevent it from entering the disengaged position, the plug-in coupling system has a locking device. This locking device is designed to be able to enter a locked position and a released position. In other words, the locking device specifically has two states, namely a locked position and a released position. In the locked position, the locking device specifically prevents escape from the connected position to the disengaged position in a form-fitting manner. However, in the released position, the locking device does not prevent the transfer from the connected position to the disengaged position. The locking device can be, for example, a hook-and-eyelet system (Flaken-Ösen-System). Alternatively or additionally, preferably, the locking device may also be / have a locking pin system and / or include a locking pin that, in a form-fitting manner, prevents transfer from the engaged position to the disengaged position in the locked position. By using a form-fitting anti-disengagement device, it is possible to ensure, in a particularly simple and effective manner, that the locking device can reliably prevent unintended withdrawal from the engaged position to the disengaged position.

[0006] Advantageously, the locking device has an actuator capable of moving the locking device to a locked position or a released position. Therefore, the actuator is a component capable of actively influencing the state of the locking device. By using the actuator, the position or state of the locking device can be influenced in a targeted manner. Advantageously, the actuator has an energy port through which the actuation of the actuator can be specifically targeted. In particular, the actuator is designed to be bidirectional. Bidirectional here means that the actuator can move the locking device to both the locked and released positions, or vice versa.

[0007] In a particularly preferred embodiment, the locking device has a biasing mechanism that forces the locking device into a locked or released position. For example, a spring or other accumulating member attempts to guide or hold the locking device into the locked or released position, in a particularly constant manner. This ensures that the locking device remains in its defined state even in the event of a power outage, thereby further enhancing system security.

[0008] In advantageous embodiments, the actuator is a compressed air cylinder, a magnetic actuator, a linear motor, or a hydraulic cylinder. By designing the actuator as a compressed air cylinder, the compressed air system present in commercial vehicles can be used to drive the actuator in a particularly simple manner, resulting in an actuator that is particularly easy to drive and install. When the actuator is designed as a magnetic actuator and / or an electric actuator, the on-board power supply system of the commercial vehicle can be used in a particularly simple manner. If the actuator is designed as a linear motor, the actuator is particularly compact, thereby saving valuable installation space. If the actuator is designed as a hydraulic cylinder, a particularly lightweight yet compact actuator can be ensured, thereby also saving valuable installation space.

[0009] Advantageously, the locking device has a locking member (particularly a locking pin) and / or a locking structure, wherein the locking member and the locking structure are particularly designed to be complementary to each other. "Designed to be complementary to each other" is particularly understood to mean that the locking member can be inserted into the locking structure, but advantageously no interference fit is formed between the locking member and the locking structure. Alternatively or additionally, preferably, complementarity can also be understood as the locking member and the locking structure having the same or similar basic structural cross-section, such as a circular or elliptical cross-section, and being guided into each other. The locking member is particularly designed as a convex contact of the locking device and is advantageously movable by an actuator. On the other hand, the locking structure is advantageously designed as a mating member of the locking device, particularly a concave structure, and interacts with the locking member in a form-fitting manner in the locked position, such that the form-fitting manner prevents transfer from the engaged position to the disengaged position. However, the locking structure can also be designed, for example, a ball or a stop element, behind which the locking member can engage in a form-fitting manner. Locking components and / or locking structures may be, for example, mechanical intermediate elements, particularly advantageously retaining rings, piston tail rods, or collars with barbs.

[0010] Advantageously, the locking device can be designed such that its locking action is not directly achieved by the actuator. This is particularly advantageous, for example, because it allows the locked position to be maintained even if the actuator fails. In other words, the actuator can only indirectly move the locking device to the locked position and / or the released position. In the context of this invention, this type of locking device can be referred to as an indirect-acting locking device. For example, this can be achieved by a ring movable by the actuator, which surrounds the resilient locking structure in the locked position to prevent or limit elastic deformation of the locking structure, so that the element received in the locking structure cannot leave the locking structure. However, in the released position, the ring moves to allow elastic deformation of the locking structure, thereby allowing the received element to be guided out of or into the locking structure.

[0011] Advantageously, the locking member is mounted and / or held such that it can be moved, particularly by means of an actuator, by a translational movement specifically along the direction of movement from a locked position to a released position. Thus, the locking member is specifically mounted or held on or fixed by the actuator or its base, such that the locking member is transferred from the locked position to, or is capable of transferring to, the released position, or vice versa, by a translational movement of the locking member (particularly a single translational movement). This translational movement of the locking member occurs along the direction of movement of the locking member. Due to the single translational movement of the locking member, a particularly compact and easy-to-construct locking device can be achieved, making the locking device particularly cost-effective and space-saving.

[0012] In an advantageous embodiment, the direction of movement is transverse to, and particularly perpendicular to, the insertion direction. Transverse means that the smaller angle between the direction of movement and the insertion direction is at least 30°, preferably at least 60°, and particularly preferably at least 75°, and / or no more than 90°. By making the direction of movement and the insertion direction transverse to each other, a particularly compact arrangement in the insertion direction can be achieved. If the angle between the direction of movement and the insertion direction is at least 30°, a locking device that is particularly easy to manufacture can be achieved. If the angle is at least 60°, a particularly compact locking device can be achieved in both the direction of movement and the insertion direction. If the angle between the direction of movement and the insertion direction is at least 75°, this can achieve a particularly robust form-fit device. However, it is particularly preferred that the direction of movement and the insertion direction are perpendicular to each other, as this allows for a particularly compact and simultaneously very robust, easy-to-manufacture, and easy-to-assemble locking device.

[0013] Advantageously, the locking structure is a groove or recess for receiving the locking member, or the locking structure can be designed as a protrusion. By designing the locking structure as a groove or recess, a locking device that is particularly space-saving and easy to manufacture can be achieved. In this context, a recess means a concave design that can be manufactured by processes such as stamping or milling, for example, drilling. If the locking structure is designed as a protrusion, a device that can withstand specific mechanical forces can be achieved in this way, such that by designing the locking device as a protrusion, mechanical weakening of the element having the locking structure can be avoided or at least reduced.

[0014] Advantageously, the main and auxiliary coupling devices have one or more guiding structures, particularly in the form of guide mandrels or guide sleeves. The guiding structures are used to guide the main coupling device relative to the auxiliary coupling device. In other words, the guiding structures of the main and / or auxiliary coupling devices ensure that they can be safely guided from a separated position to a coupled position. Specifically, the guiding structures are designed to prevent unwanted movement, particularly movement perpendicular to the insertion direction, especially in a form-fitting manner. The guiding structures can be designed, for example, as guide mandrels or complementary guide receiving structures, particularly guide sleeves. These guide receiving structures are particularly concave embodiments of the guiding element, which can be used and / or designed, for example, to securely receive the guide mandrel. Advantageously, the guiding element extends in the insertion direction. By using the guiding structures, a safe transfer, particularly to the coupled position, can be achieved in insert-type coupling systems.

[0015] In a particularly preferred embodiment, at least one locking structure and / or multiple locking structures are arranged or formed on and / or within the guide structure. By using the guide structure and / or some of the guide structures to form part of the locking device, a particularly simple and low-component design of the plug-in coupling system with the locking device can be achieved. Furthermore, this also enables particularly easy maintenance and / or replacement of the locking device, as it increases or simplifies the accessibility of the locking structure.

[0016] Advantageously, the main coupling device and / or the secondary coupling device have a receiving structure, particularly a receiving structure for receiving or guiding a guide structure, wherein the receiving structure allows the mating member (particularly the guide structure) to be inserted by elastic deformation in the released position, and wherein the receiving structure, in particular, prevents the mating member from being removed in a form-fitting manner in the locked position. For example, the receiving structure may be a guide sleeve. The receiving structure may have particularly inwardly projecting barbs or structures that form a locking contact with the mating member in the locked position. In particular, if the receiving structure is part of the main coupling device, the mating member is part of the secondary coupling device, or vice versa. In particular, the mating member may be a guide mandrel as described above and below.

[0017] Advantageously, the receiving structure has a slot, particularly in the insertion direction. This increases the elastic deformation capacity of the receiving structure, especially to accommodate the largest possible mating member. Furthermore, this reduces the amount of energy required for connection, resulting in an energy-efficient device.

[0018] In a preferred embodiment, a surrounding and / or movable ring prevents the receiving structure from allowing insertion or removal of the mating member through elastic deformation (particularly elastic deformation of the receiving structure) in the locked position. For example, the ring can thus surround the receiving structure such that the ring prevents or hinders deformation of the receiving structure in a form-fitting manner. The ring can be moved, for example, by an actuator or said actuator. Thus, an indirect-acting locking device can be realized. Advantageously, the ring can be advantageously moved by an actuator or said actuator in the insertion direction or in a direction parallel to the insertion direction in order to achieve a particularly small size.

[0019] Advantageously, a secondary locking device is provided, wherein the secondary locking device is designed or constructed such that, in its locked position, it prevents transfer from the engaged position to the disengaged position by form-fit or force-fit, and in its released position, it allows transfer from the engaged position to the disengaged position. In other words, a second locking device may exist, which in particular achieves locking in a manner independent of the (first) locking device. This can further increase the security of the system. In this document, the secondary locking device may have all the features, advantages, embodiments, or designs of the locking devices described above or below.

[0020] Preferably, the locking device and the auxiliary locking device are based on different locking mechanisms. In other words, the energy sources (particularly the energy sources of the actuator, locking device, and auxiliary locking device) can be different. For example, one actuator can be a pneumatic actuator, while the other can be a hydraulic actuator. Furthermore, the locking device can have a direct locking effect, while the auxiliary locking device can have an indirect locking effect, or vice versa. Direct locking occurs particularly when the actuator moves the locking member or locking structure and the locking member or locking structure then locks itself, particularly in a form-fit manner. On the other hand, indirect locking occurs particularly when the locking device only indirectly moves the locking member or locking structure into the locked position and therefore does not directly lock itself. Alternatively or additionally, preferably, "different locking mechanisms" can also be understood as different locking action deployments. For example, the locking device can operate in a form-fit manner, while the auxiliary locking device can operate in a non-form-fit manner, particularly in a force-fit manner and / or by a permanent force, advantageously by a permanent force in the insertion direction. This permanent force can, for example, be achieved by a permanently pressurized compressed air cylinder when the compressed cylinder is in the locked position.

[0021] Advantageously, the main coupling device and / or the auxiliary coupling device have one or more drives, wherein the drives are specifically designed to move the main coupling device and / or the auxiliary coupling device from a coupled position and / or from a coupled position to a coupled position by translational movement in the insertion direction. For example, the plug-in coupling system can therefore be designed such that the transfer from the coupled position to the coupled position or from the coupled position to the coupled position is achieved not by the approach of the vehicle to be coupled, but by a separate drive. In particular, this has the advantage that the mechanical load acting on the main coupling device and the auxiliary coupling device during the coupling process between the tractor and the towed vehicle can be reduced, making it possible to achieve a particularly lightweight main coupling device or auxiliary coupling device. Therefore, the drives in the plug-in coupling system can effectively increase the available payload of the commercial vehicle.

[0022] For example, the driver or one of the drivers can be a linear motor, a hydraulic motor, a hydraulic piston, and / or a pneumatic piston.

[0023] In an advantageous embodiment, the locking structure is arranged or formed on or within the actuator, particularly in or on the piston rod of the actuator. In this way, a particularly compact and space-saving locking device can be achieved, which also effectively prevents unintended separation or transfer from the engaged position to the disengaged position. For example, the locking structure can therefore be designed as a groove or recess in or on the piston rod of the actuator, which may be, for example, a double-acting cylinder. Thus, in the event of an unintentional attempt to transfer from the engaged position to the disengaged position, the number of mechanically stressed components can be reduced, thereby saving material and weight.

[0024] Another aspect of the invention relates to a traction seat connector comprising an insert-type coupling system as described above or below. Specifically, the traction seat connector includes a traction seat coupling plate and a main pin, wherein a main coupling device may be arranged, for example, on the traction seat coupling plate, and / or, particularly, a secondary coupling device may be arranged adjacent to the main pin. In this document, "adjacent arrangement" can be understood as a maximum distance of 2 m, preferably 1 m, between two components when the system is in an assembled state, particularly in the coupled position.

[0025] Another aspect of the invention relates to a commercial vehicle assembly comprising a towing vehicle coupling and / or a towing vehicle coupling system as described above or below. Specifically, the commercial vehicle assembly includes a tractor unit and a towed vehicle. Therefore, the commercial vehicle assembly can, for example, be formed from a tractor unit and a semi-trailer. Attached Figure Description

[0034] Figure 1 A cross-sectional view of the plug-in coupling system 1 is shown. The cross-sectional plane is defined by the movement direction L and the insertion direction S. The plug-in coupling system 1 includes a main coupling device 10 and a secondary coupling device 40. The main coupling device 10 and the secondary coupling device 40 can move relative to each other in the insertion direction S, wherein... Figure 1 In the middle, the coupling system 1 is in the connected position. The disengaged position of the plug-in coupling system 1 is in the insertion direction S, which is different from the connection position. Figure 1 The connection positions shown are spaced apart. The main connection device 10 has a plug holder 12, which has a transmission contact portion 14 extending in the insertion direction S. (As shown) Figure 1As exemplarily shown, the guide structure 70 is laterally spaced from the transmission contact 14 at a distance in the movement direction L. The guide structure 70 may be designed as a guide mandrel and a guide sleeve. Both the main coupling device 10 and the auxiliary coupling device 40 have a guide structure 70 designed as a guide mandrel and a guide structure 70 designed to receive the guide mandrel. The main coupling device 10 has an actuator 60, which is designed as a double-acting cylinder and can move the main coupling device 10 relative to the auxiliary coupling device 40 in the insertion direction S so that the insertion coupling system 1 enters the coupling position or the disengagement position. To prevent lateral movement of the main coupling device 10, the main coupling device 10 has a lateral guide structure 70 in the form of a linear guide. To prevent undesirable transfer from the coupling position to the disengagement position in a form-fit manner, the insertion coupling system 1 has a locking device 50. The locking device 50 has an actuator 52, a locking member 54, and a locking structure 56. Actuator 52 enables the locking member 54 (a locking pin in the illustrated variant) to move in the direction of movement L, so as to transfer the locking device 50 from the illustrated release position to the locked position. For this purpose, the locking member 54 performs a purely translational motion in the direction of movement L. The locking structure 56 is designed as a complementary locking structure to the locking member 54, and is shown as a drilled hole in the illustrated embodiment.

[0035] Figure 2 As shown in detail Figure 1 The region marked B in the middle, where, from Figure 2 It can be seen that the locking component 54 is designed as a locking pin, while the locking structure 56 is designed as a drilled hole.

[0036] Figure 3 An external view of the plug-in connection system 1 is shown, which can be specifically matched. Figure 1 The plug-in connection system 1 shown. Figure 3 Also shown is a plug-in connection system 1 in the connection position.

[0037] Figure 4 A side view of the insert-type coupling system 1 is shown. In the illustrated embodiment, the locking member 54 is designed as a slider that can engage with the distal end of the guide mandrel in a cut-fit manner to prevent movement of the main coupling device 10 relative to the secondary coupling device 40 in the insertion direction S.

[0038] Figure 5 It shows Figure 4 A detailed view of the area marked A in the image. From... Figure 5As can be seen, the locking member 54 is designed to be translationally movable, capable of engaging with the locking structure 56 in a form-fitting manner. The locking structure 56 forms the distal end of the guide structure 70 in the insertion direction S. In other words, in Figure 5 In the embodiment shown, the locking structure 56 is formed as a protruding element and thus as a convex element.

[0039] Figure 6 A traction seat connector including a plug-in coupling system 1 is shown. Figure 6 In this configuration, the plug-in connection system 1 is in a disengaged position, preventing the exchange of information and / or energy between the secondary connection device 40 and the primary connection device 10.

[0040] Figure 7 An indirect-acting locking device 50 is shown, which can also be a secondary locking device 80. In other words, the device shown can therefore also be an additional locking device 50. In this case, the locking action of the secondary locking device 80 / locking device 50 is indirect because the actual forced locking member 54 is formed by a receiving structure 90 in the form of a guide sleeve, which can be easily elastically deformed by a slot extending in the insertion direction S. The ring can be pushed around the receiving structure 90 by an actuator to prevent deformation in the locked position, thereby preventing the guide structure 70 received in the receiving structure 90 from escaping in a form-fit manner.
