Description
Device and Method for Coupling a Mounted Implement on a Vehicle The invention relates to a device for coupling a mounted implement, in particular a dozer blade or a mine clearing plow, on a vehicle, wherein the device comprises a rotary latch.
Other subject matter is formed by a mounted implement for a vehicle and a vehicle for receiving a mounted implement. The invention furthermore relates to a method for the emergency decoupling of a mounted implement, in particular a clearing plow or a mine clearing plow from a vehicle.
Devices for coupling such heavy mounted implements on vehicles are known. The mounted implement serve as a rule to expand the functionality of the vehicles.
Devices are known from the military area for coupling clearing plows or mine clearing devices such as mine clearing plows. US 5 786 542 describes a coupling device that comprises a ring on the vehicle side and with an upper section mounted in an articulated manner, via which section the ring can be opened and closed. For coupling a mounted implement, lugs provided on the mounted implement are placed in the ring and the ring is closed.
Furthermore, a coupling device described in EP 2 196 763 B1 is described in which shackles are disposed on the vehicle. Bolts disposed in the mounted implement engage into these shackles and couple the mounted implement on the vehicle.
However, it occurs in the military area in particular that the mounted implement is damaged or becomes stuck during use. In these instances the mobility of the vehicle carrying the mounted implement is significantly degraded or a movement of the vehicle becomes impossible. In order to protect the crew and the vehicle it is then necessary in case of an emergency to rapidly decouple the mounted implement from the vehicle and to reestablish the mobility of the vehicle.
The already cited EP 2 196 763 B1 suggests to this end drawing the bolt for decoupling the mounted implement by hydraulic pressure out of the vehicle side shackle or to separate the bolt of the mounted implement by a pyrotechnical charge from the mounted implement for an =
emergency decoupling and to perform an emergency decoupling of the mounted implement in this manner.
In the case of a mounted implement that has become stuck there are undefinable conditions of force and tension. Therefore, a reliable design of hydraulic systems that allow a reliable emergency decoupling is not possible. In addition, in these cases very great force is necessary for withdrawing the bolts from the shackles that cannot be applied by the hydraulic systems in an unfavorable case.
Pyrotechnical emergency decouplings arranged directly on the bolt of the mounted implement do constitute an improvement but can also not ensure a reliable emergency decoupling of the mounted implement. On the one hand the force of the pyrotechnical charge lasts only briefly and on the other hand the bolts have the tendency to become stuck in the coupling device so that the mounted implement is also not loosened from the vehicle by the ignition of the pyrotechnical charge.
The invention therefore has the task of achieving a reliable emergency decoupling of a mounted implement from a vehicle.
This task is solved in a device of the initially cited type by a locking device acting under lever force on the rotary latch, which device is prestressed in the direction of the locking position of the rotary latch and can be relaxed for the emergency decoupling of the mounted implement.
The rotary latch can be held in the locking position with a force that is low in comparison to the locking force by the prestressing of the rotary latch under lever force.
For the emergency decoupling the rotary latch is relaxed, so that the mounted implement and the vehicle can separate from one another without components of the coupling device of the mounted implement and the vehicle clamping to each other. In order to open the rotary latch and therefore to separate the vehicle and the mounted implement, it can be sufficient to take the prestressing force from the rotary latch. To this end much less force is required than for the direct removal of the bolt. Consequently, a simple and reliable emergency decoupling is secured.
The lever force is transferred via a lever onto the rotary latch. As a result of the transfer of the force of the locking device via the lever onto the rotary latch it is possible to unlock the =
=
rotary latch aside from the bolt. Deformations and tensions in the area of the bolt can therefore not prevent an effective emergency decoupling.
According to another embodiment of the invention the locking device comprises a bent lever.
The bent lever serves to strengthen the force acting on the rotary latch. A
great strengthening of force with low construction space is achieved with a bent lever. The bent lever can comprise two shanks connected to one another in an articulated manner. Both shanks of the bent lever are preferably equally long.
Another teaching of the invention provides that the rotary latch comprises a first holding element that can move from an open position into the locking position and a second element, that is in particular rigidly connected to the device, for holding the bolt in the rotary latch. In this manner a simple and economical construction results. Both holding elements can also be constructed to be movable.
The holding elements preferably have only round receiving surfaces for holding a round, cylindrical bolt. However, even bolts with another shape and holding elements with holding surfaces corresponding to these bolts are conceivable. For example, the bolt can be constructed as a four-cornered shaft. In this case the rotary latch can be constructed in such a manner that it can receive moments.
In another embodiment of the device a lever, in particular a bent lever, attacks the movable holding element of the rotary latch. The other shank of the bent lever preferably attacks a rigid part of the device. The shanks can be disposed vertically or diagonally in the device.
If both holding elements are to be constructed to be movable, it is advantageous if each shank of the bent lever attacks a holding element. However, as an alternative, one bent lever can also attack each holding element.
Another further development of the invention suggests that the angle between the two shanks of the bent lever in the locking position of the rotary latch is between 160 degrees and 180 degrees, preferably between 170 degrees and 180 degrees, especially preferably between 175 degrees and 180 degrees. The strengthening effect of the bent lever increases more, the more the angle between the shanks approaches 180 degrees.
Furthermore, it proved to be advantageous as regards the construction that the rotary latch and/or a lever, especially a bent lever, has a stop in the locked position of the rotary latch that ensures a predetermined play between the two holding elements and a bolt to be held in them.
On the one hand this ensures a simple connecting and separating of the vehicle and the mounted implement by inserting the bolt into and drawing it out from the rotary latch during the normal coupling and decoupling. There is a predefined play between the bolt and the prestressed rotary latch so that the bolt is not clamped in the rotary latch.
On the other hand, it can be ensured by the stop that the bent lever is not bent and as a consequence the prestressing action of the locking device on the rotary latch is cancelled.
In a further embodiment of the invention the locking device comprises a force-producing apparatus for producing the lever force. The force-producing apparatus makes the prestressing force available for the rotary latch.
It proved to be advantageous from a constructive viewpoint that the force-producing apparatus comprises a spring and/or a screw element. The spring and/or the screw element make possible a very precise adjustment of the force acting on the lever and therefore on the rotary latch. The spring of the force-producing element is especially preferably constructed as a pressure spring.
A further embodiment of the device provides that the force-producing apparatus acts on the bent lever in the area of an articulation between the shanks of the bent lever. In order to ensure the most efficient and reliable transfer of force possible from the force-producing apparatus onto the bent lever, it proved to be especially advantageous if the direction of the action of the force-producing apparatus is orthogonal to a connection line running from the two outer articulated points or articulations of the shanks of the bent lever.
The force-producing apparatus and/or the rotary latch is/are preferably received substantially protected in the device. The device can have a housing for protection. The housing preferably protects the force-producing apparatus and/or the bent lever, particularly laterally, from environmental influences and/or mechanical effect from the outside. The housing can be formed in particular by side walls of the device. The side walls preferably also form in particular rigid holding elements of the rotary latch at the same time.
Another embodiment of the invention provides that for the emergency decoupling the flow of force between the force-producing apparatus and the rotary latch can be interrupted, cancelled and/or reversed, in particular mechanically or explosively. As a result of the interruption, cancelling and/or reversal of the flow of force the action of the force-producing =
=
apparatus on the rotary latch in the direction of the locking position can be cancelled. The flow of force can especially preferably be interrupted pyrotechnically. As a result of the interruption and/or reversal of the flow of force the prestressing force can be taken from the rotary latch so that it can be opened without resistance.
The flow of force is preferably interrupted by destroying the force-producing apparatus. To this end, for example, a cutting charge can be provided in the force-producing apparatus that destroys the force-producing apparatus and therefore cancels the prestressing of the rotary latch.
Additionally or alternatively, the flow of force can be interrupted by bending a spring provided in the force-producing apparatus in order to cancel the prestresses of the rotary latch in this manner.
Furthermore, the flow of force between the force-producing apparatus and the rotary latch can be interrupted or cancelled in that at least one connection between the force-producing apparatus and the device is interrupted or separated, for example, by removing a bearing bolt.
The bearing bolt can be removed by motor or manually. Furthermore, a cutting charge can also destroy or loosen an anchoring of the force-producing apparatus and as a result cancel the prestressing of the rotary latch. Upon a canceling of the flow of force the force-producing apparatus can continue to be connected to the lever or the rotary latch without, however, continuing to exert force, e.g., in the case of a spring as the force-producing element by relaxing the spring.
Another embodiment provides a means, in particular a cable, with which the flow of force between the force-producing element in the rotary latch can be reversed, e.g., by further compressing the spring.
Furthermore, it proved to be especially advantageous if the force-producing apparatus comprises at least one of the following elements: a screw head, a threaded section, a tapered, cylindrical section with a cutting charge and/or comprising a spring in order to prevent the spring from bending, it is preferably conducted in a casing or a container closed on one side.
In addition, it is advantageous for a better mounting of the force-producing element if the outside diameter of all sections on one side of the threaded section is smaller than the inside diameter of the threaded section.
=
A further embodiment of the invention provides that the locking device can be relaxed manually, by motor and/or by remote control. In this manner the emergency decoupling can be carried out by the vehicle crew from the protected area of the vehicle.
Furthermore, a mounted implement and/or vehicle of the initially cited type is suggested to solve the above task that comprises one, preferably two devices of the already described type so that the already described advantages are achieved.
It proved to be advantageous M a further embodiment of the mounted implement and/or vehicle if the mounted implement or vehicle comprises two devices and if the devices are disposed in such a manner that the middle axis of the bolts to be received in the devices are located on a straight line.
It is advantageous for a better separation of the mounted implement and the vehicle if the device is disposed on the mounted implement and/or the vehicle in such a manner that the movable holding element is disposed above the holding element fixed to the device.
It furthermore proved to be advantageous if the vehicle as well as the mounted implement comprise devices of the previously described type that can be connected by a common bolt.
In this case, if the decoupling of the device on the vehicle or on the mounted implement is not successful, the emergency decoupling can also be initiated on the other one.
According to another teaching of the invention the mounted implement and/or the vehicle can comprise an interface for the hydraulic and/or electrical supply of the mounted implement by the vehicle. These interfaces or connections can be separated during the emergency decoupling in the manner known from the prior art. Interfaces for controlling the mounted implement by the vehicle can also be provided.
In a method of the initially cited type the previous task is solved in that a locking device acting under lever force on a rotary latch is relaxed, wherein the mounted implement is decoupled from the vehicle. Consequently, a device of the type already described can be used, wherein the advantages already described result.
In another embodiment of the method the rotary latch is held in a locking position before the decoupling by a lever, in particular a bent lever. The lever strengthens the force with which the rotary latch is held in a locking position.
=
=
According to another embodiment of the invention, for the emergency decoupling the flow of force between the rotary latch and enforce-producing apparatus is interrupted or vice versa.
As a result of the interruption of the flow of force the prestressing of the rotary latch is canceled so that the vehicle and the mounted implement can be readily decoupled.
A further development of the invention suggests that in order to interrupt the flow of force the force-producing apparatus is destroyed, in particular mechanically or explosively, especially preferably pyrotechnically. The prestressing force on the rotary latch is canceled by the destruction of the force-producing apparatus so that the rotary latch can open and free the bolt.
This can take place mechanically, for example by a purposefully induced bending of a spring present in the force-producing apparatus. The force-producing apparatus can be destroyed explosively, in particular pyrotechnically by a cutting charge in the force-producing apparatus.
According to another embodiment of the invention the flow of force is interrupted and/or reversed manually, by motor and/or by remote control. If the flow of force can be interrupted or reversed by motor or by remote control, the vehicle crew can initiate, e.g., the emergency decoupling from the protected vehicle.
It furthermore proved to be advantageous from a constructive viewpoint that the rotary latch is opened by the intrinsic weight of the mounted implement and/or of the vehicle and the mounted implement is decoupled from the vehicle.
The device, the mounted implement and/or the vehicle can comprise appropriate means for carrying out the method.

Many vehicles 2, in particular work vehicles and/or military vehicles have coupling positions like the vehicle 2 shown in fig. 1 to which external mounted implements 3 of different types can be coupled to the vehicle 2. The spectrum of use and the range of functions of vehicles 2 can be flexibly adapted to different tasks by the possibility of coupling different work devices.
Uniform coupling points on the vehicle 2 are preferably used for the different mounted implements 3. In addition to purely mechanical coupling points the mounted implements and/or the vehicle can also comprise additional interfaces for the hydraulic and/or electrical supply of the mounted implement by the vehicle. Additionally or alternatively, a control interface between the mounted implement in the vehicle can also be provided, so that the mounted implement can be controlled from the vehicle.
A mounted implement 3 for groundwork or earthwork is coupled to the vehicle 2 in fig. 1.
The mounted implement 3 is a dozer blade 4. Alternatively, for example, a mine clearing device such as a mine clearing plow could be coupled to the same coupling points.
It is generally customary to dispose the mounted implements 3, as is shown in fig. 1, on the front of the vehicle 2. However, the coupling points and with them the mounted implements 3 can be disposed on the rear on the vehicle 2 or, for example, on the roof of the vehicle 2.
As a rule, coupling points comprise, in addition to the mechanical coupling points, interfaces for the electrical components and/or the hydraulic components for supplying the mounted implement and comprise control interfaces for the mounted implement 3. In addition. the mounted implements 3 can comprise additional apparatuses that expand their spectrum of functions. They can be, for example, sensors for the control and/or for the operation of the device or, however, also headlights that can additionally illuminate the working range of the mounted implement 3.
When using mounted implements 3 that work the ground such as e.g., dozer blades 4 and/or mine clearing plows, it can occur that they stall. However, the mobility of the vehicles 2 carrying them is significantly limited by stalled mounted implements 3 or a movement of the vehicles 2 is completely suppressed. In particular in the case of military vehicles 2 it is necessary for the protection of the crew to restore as rapidly as possible the mobility of the vehicles 2. This is achieved by decoupling the mounted implement 3 from the vehicle 2. The device 1 according to the invention, the mounted implement 3 according to the invention, the vehicle 2 according to the invention and the method according to the invention make possible an especially rapid and reliable emergency decoupling of the mounted implement 3 from the vehicle 2, in particular even in the case of high, unknown tension states due to a stalled mounted implement 3.
At first, a survey of the basic construction of the device 1 will be given using fig. 2 before a first embodiment is described more precisely using fig. 3 to 6, and subsequently a second embodiment will be described in detail using fig. 8 to 13. The design of the force-producing apparatus 20 constitutes the essential difference between the two embodiments.
Fig. 2 shows the device in a perspective top view. The device 1 comprises as elements essential for the invention a rotary latch 5 and a locking device 10. The rotary latch 5 comprises a first holding element 6 that can move from an open position to a locking position and a second holding element 7 fixed to the device. The movable holding element 6 is supported in the holding element 7 fixed to the device in such a manner that it can pivot via an articulation bolt 8. In fig. 2 the rotary latch 5 is in a locking position and comprises a bolt 9. The holding elements 6, 7 of the device 1 shown are constructed in the manner of a double gripping device. They have two holding surfaces.
In addition, the rotary latch 5 has a stop 30 against which the movable holding element 6 strikes in a locking position of the rotary latch 5. The stop 30 ensures that the rotary latch 5 surrounds the bolt 9 but does not clamp it.
=
The locking device 10 comprises a lever and a force-producing element 20. The force-producing element 20 acts via the lever on the movable holding element 6 and holds the rotary latch 5 in a locking position in this manner. It is possible with the lever to unlock the rotary latch 5 aside from the bolt 9 to be held by it with the aid of the force-producing element 20. The locking device 10 is disposed, as can be well-recognized in fig. 2, inside the device 1 and protected by side walls 18, 19. The side walls 18, 19 form a type of housing for the protection of the force-producing apparatus 20 and the bent lever 11. The side walls 18, 19 are also constructed as integral holding elements 7 fixed to the device.
The lever of the locking device, which lever is constructed as bent lever 11, is described in detail in the following.
The bent lever 11 is formed by two shanks 12, 13 connected in an articulated manner to one another. The shanks 12, 13 have substantially the same length. A shank 12 is connected in an articulated manner by the articulation 15 to the movable holding element 6.
The other shank 13 is connected via the articulation 16 to aa part of the device fixed to the device 1 and in the exemplary embodiment to a side wall 18, 19 that simultaneously forms an integral holding element 7 fixed to the device.
In a locking position of the rotary latch 5 the shanks 12, 13 of the bent lever are disposed almost horizontally in the device, as the figures 3, 4, 8 and 9 show. However, the bent lever can also be disposed horizontally or diagonally in the device.
A shank 13 has a U-shaped end. The other shank 12 of the bent lever 11 is received in an articulated manner in this U-shaped end. A curve stopped surface 17 for the force-producing element 20 is formed on the other shank 12 in the area of the articulation 14 with the shank.
The lever translation of the bent lever 11 is dependent on the angle A formed by the shanks 12, 13. The more the angle A approaches 180 degrees, the more the bent lever 11 strengthens the force of the force-producing element 20.
The force-producing element 20 extends in its longitudinal direction from the stop 17 on the bent lever to its fastening on the point of the device 1 that is fixed to the device. In the first exemplary embodiment shown the force-producing element 20 is screwed into the device I.
The prolongation of the longitudinal axis of the force-producing element 20 runs substantially centrally through the articulation 14, by which the two shanks 12, 13 of the bent lever II are connected to each other in an articulated manner. The longitudinal axis of the force-=
producing element 20 is additionally designed diagonally to the connection line of the two outer articulated points of the knee lever 11.
The force-producing element 20 in accordance with the embodiment of fig. 3 to 7 will be explained using the view in fig. 7.
The force-producing element 20 comprises a section 21 for attacking a tool, which section is bordered by a threaded section 22. The latter is followed by a tapered section 23 with a cutting charge 24. The tapered section 23 borders a wider section 25 before another tapered section 26 closes the bolt-like element of the force-producing apparatus 20.
The last-cited, tapered section 26 serves to receive a spring 27. The spring 27 is guided in a casing 28 whose movement is guided by the wider section 25. The casing 28 serves for protection against bending of the spring 27. In the exemplary embodiment the casing 28 is closed on one side and therefore constructed like a container. In addition, the outside diameter of the casing is less than the inside diameter of the threaded section so that the force-producing element can be introduced from the outside of the device into the device and be screwed.
In the following the functioning of the device 1 during the emergency decoupling is described using fig. 3 to 6.
As can be seen in the fig. 3 and 4 the device 1 is in a coupled state in which the rotary latch 5 surrounds the bolt 9. The movable holding element 6 is held in the locking position via the strengthening of the force of the bent lever 11 by the force-producing element 20. The force producing element 20 is screwed into a section of the device 1 which section is fixed to the device and presses with the spring 27 against the stop 17 of the bent lever 11.
If the device 1 is to be decoupled in an emergency, the cutting charge 24 in the force-producing element 20 can be ignited, for example, by remote control from the interior of the vehicle 2. This separates the tapered section 23, as can be seen in fig. 5 and 6, and the force-producing element 20 is destroyed as a result. This interrupts the flow of force via the bent lever 11 to the movable holding element 6. As a consequence, the rotary latch 5 is no longer prestressed and is easy to open. In the exemplary embodiment the opening of the rotary latch takes place due to the intrinsic weight of the mounted implement 3 and the mounted implement 3 slides off from the bolt 9. This cancels the coupling between vehicle 2 and mounted implement 3.
=
In the following a second exemplary embodiment of the invention will be described using fig.
8 to 11. The second exemplary embodiment differs substantially from the first exemplary embodiment by the force-producing element 20 and its connection to the device 1 and to the bent lever 11. The force-producing element 20 is designed as spring 29, as can be readily recognized in the figures. The spring 29 is constructed as a pressure spring.
It is connected by one end to a part of the device 1 fixed to the device and attacks with its other end in the area of the middle articulation 14 between the shanks 12, 13 of the bent lever 11. In this manner the spring 29 prestresses the rotary latch 5 via the bent lever 11 in its locking position.
The second exemplary embodiment also comprises, as can be seen in the fig. 8 to 11, a stop 30 that ensures that the bolt 9 is not clamped in the locking position of the rotary latch 5 by it.
In this manner a simple mounting of a mounted implement 3 on a vehicle 2 is ensured by inserting and withdrawing the bolt 9. Alternatively, a stop 30 can also be provided on the bent lever 11 that also has the result that the bolt 9 is not clamped.
The device according to the second exemplary embodiment can be opened for an emergency in different ways.
For an emergency opening, on the one hand the force-producing element 20, in the present case the spring 29, can be loosened on one end from the device 1, for example, by withdrawing a bearing bolt 31, 32 with which the force-producing element 20 is connected to the device 1. The bearing bolt 32 is preferably removed, that connects the force-producing element 20 on the end facing away from the bent lever 11 to the device 1. In this manner the flow of force from the force-producing element 20 to the rotary latch 5 is cancelled. During the loosening of the bearing bolt 31 the flow of force would be interrupted.
The bearing bolts 31, 32 can be removed manually or by motor for the emergency opening.
For better accessibility to the bearing bolts 31, 32 the side walls 18, 19 in the area of the bearing bolts 31, 32 can comprise a perforation. In fig. 8 the perforation is designed as hole 33.
On the other hand, for the emergency opening the spring 29 in the force-producing element 20 can be compressed to such an extent that the rotary latch 5 opens, as shown in fig. 10 and 11. For the compression of the spring 29, for example, a traction means (not shown) that attacks the bent lever 11 and a section running parallel to the force-producing element 20 can =
be used. By pulling on this traction means, e.g., a cable, the pressure spring 29 of the force-producing element 20 can be further tightened and therefore the flow of force between it and the bent lever 11 and therefore the rotary latch 5 can be reversed and therefore the rotary latch 5 can be opened. The pulling on the traction means can take place either, for example, with the aid of an electrical motor or, however, as an alternative, even manually in order to initiate the emergency decoupling. Therefore, a simple and reliable emergency decoupling is given.
The previously described device 1 as well as the previously described mounted implement 3 and the previously described vehicle 2 and the previously described method for the coupling and emergency decoupling of a mounted implement 3 from a vehicle 2 are distinguished in particular in that they ensure a simple and reliable emergency decoupling requiring only little force by opening the rotary latch 5.

Other subject matter is formed by a mounted implement for a vehicle and a vehicle for receiving a mounted implement. The invention furthermore relates to a method for the emergency decoupling of a mounted implement, in particular a clearing plow or a mine clearing plow from a vehicle.
Devices for coupling such heavy mounted implements on vehicles are known. The mounted implement serve as a rule to expand the functionality of the vehicles.
Devices are known from the military area for coupling clearing plows or mine clearing devices such as mine clearing plows. US 5 786 542 describes a coupling device that comprises a ring on the vehicle side and with an upper section mounted in an articulated manner, via which section the ring can be opened and closed. For coupling a mounted implement, lugs provided on the mounted implement are placed in the ring and the ring is closed.
Furthermore, a coupling device described in EP 2 196 763 B1 is described in which shackles are disposed on the vehicle. Bolts disposed in the mounted implement engage into these shackles and couple the mounted implement on the vehicle.
However, it occurs in the military area in particular that the mounted implement is damaged or becomes stuck during use. In these instances the mobility of the vehicle carrying the mounted implement is significantly degraded or a movement of the vehicle becomes impossible. In order to protect the crew and the vehicle it is then necessary in case of an emergency to rapidly decouple the mounted implement from the vehicle and to reestablish the mobility of the vehicle.
The already cited EP 2 196 763 B1 suggests to this end drawing the bolt for decoupling the mounted implement by hydraulic pressure out of the vehicle side shackle or to separate the bolt of the mounted implement by a pyrotechnical charge from the mounted implement for an =
emergency decoupling and to perform an emergency decoupling of the mounted implement in this manner.
In the case of a mounted implement that has become stuck there are undefinable conditions of force and tension. Therefore, a reliable design of hydraulic systems that allow a reliable emergency decoupling is not possible. In addition, in these cases very great force is necessary for withdrawing the bolts from the shackles that cannot be applied by the hydraulic systems in an unfavorable case.
Pyrotechnical emergency decouplings arranged directly on the bolt of the mounted implement do constitute an improvement but can also not ensure a reliable emergency decoupling of the mounted implement. On the one hand the force of the pyrotechnical charge lasts only briefly and on the other hand the bolts have the tendency to become stuck in the coupling device so that the mounted implement is also not loosened from the vehicle by the ignition of the pyrotechnical charge.
The invention therefore has the task of achieving a reliable emergency decoupling of a mounted implement from a vehicle.
This task is solved in a device of the initially cited type by a locking device acting under lever force on the rotary latch, which device is prestressed in the direction of the locking position of the rotary latch and can be relaxed for the emergency decoupling of the mounted implement.
The rotary latch can be held in the locking position with a force that is low in comparison to the locking force by the prestressing of the rotary latch under lever force.
For the emergency decoupling the rotary latch is relaxed, so that the mounted implement and the vehicle can separate from one another without components of the coupling device of the mounted implement and the vehicle clamping to each other. In order to open the rotary latch and therefore to separate the vehicle and the mounted implement, it can be sufficient to take the prestressing force from the rotary latch. To this end much less force is required than for the direct removal of the bolt. Consequently, a simple and reliable emergency decoupling is secured.
The lever force is transferred via a lever onto the rotary latch. As a result of the transfer of the force of the locking device via the lever onto the rotary latch it is possible to unlock the =
=
rotary latch aside from the bolt. Deformations and tensions in the area of the bolt can therefore not prevent an effective emergency decoupling.
According to another embodiment of the invention the locking device comprises a bent lever.
The bent lever serves to strengthen the force acting on the rotary latch. A
great strengthening of force with low construction space is achieved with a bent lever. The bent lever can comprise two shanks connected to one another in an articulated manner. Both shanks of the bent lever are preferably equally long.
Another teaching of the invention provides that the rotary latch comprises a first holding element that can move from an open position into the locking position and a second element, that is in particular rigidly connected to the device, for holding the bolt in the rotary latch. In this manner a simple and economical construction results. Both holding elements can also be constructed to be movable.
The holding elements preferably have only round receiving surfaces for holding a round, cylindrical bolt. However, even bolts with another shape and holding elements with holding surfaces corresponding to these bolts are conceivable. For example, the bolt can be constructed as a four-cornered shaft. In this case the rotary latch can be constructed in such a manner that it can receive moments.
In another embodiment of the device a lever, in particular a bent lever, attacks the movable holding element of the rotary latch. The other shank of the bent lever preferably attacks a rigid part of the device. The shanks can be disposed vertically or diagonally in the device.
If both holding elements are to be constructed to be movable, it is advantageous if each shank of the bent lever attacks a holding element. However, as an alternative, one bent lever can also attack each holding element.
Another further development of the invention suggests that the angle between the two shanks of the bent lever in the locking position of the rotary latch is between 160 degrees and 180 degrees, preferably between 170 degrees and 180 degrees, especially preferably between 175 degrees and 180 degrees. The strengthening effect of the bent lever increases more, the more the angle between the shanks approaches 180 degrees.
Furthermore, it proved to be advantageous as regards the construction that the rotary latch and/or a lever, especially a bent lever, has a stop in the locked position of the rotary latch that ensures a predetermined play between the two holding elements and a bolt to be held in them.
On the one hand this ensures a simple connecting and separating of the vehicle and the mounted implement by inserting the bolt into and drawing it out from the rotary latch during the normal coupling and decoupling. There is a predefined play between the bolt and the prestressed rotary latch so that the bolt is not clamped in the rotary latch.
On the other hand, it can be ensured by the stop that the bent lever is not bent and as a consequence the prestressing action of the locking device on the rotary latch is cancelled.
In a further embodiment of the invention the locking device comprises a force-producing apparatus for producing the lever force. The force-producing apparatus makes the prestressing force available for the rotary latch.
It proved to be advantageous from a constructive viewpoint that the force-producing apparatus comprises a spring and/or a screw element. The spring and/or the screw element make possible a very precise adjustment of the force acting on the lever and therefore on the rotary latch. The spring of the force-producing element is especially preferably constructed as a pressure spring.
A further embodiment of the device provides that the force-producing apparatus acts on the bent lever in the area of an articulation between the shanks of the bent lever. In order to ensure the most efficient and reliable transfer of force possible from the force-producing apparatus onto the bent lever, it proved to be especially advantageous if the direction of the action of the force-producing apparatus is orthogonal to a connection line running from the two outer articulated points or articulations of the shanks of the bent lever.
The force-producing apparatus and/or the rotary latch is/are preferably received substantially protected in the device. The device can have a housing for protection. The housing preferably protects the force-producing apparatus and/or the bent lever, particularly laterally, from environmental influences and/or mechanical effect from the outside. The housing can be formed in particular by side walls of the device. The side walls preferably also form in particular rigid holding elements of the rotary latch at the same time.
Another embodiment of the invention provides that for the emergency decoupling the flow of force between the force-producing apparatus and the rotary latch can be interrupted, cancelled and/or reversed, in particular mechanically or explosively. As a result of the interruption, cancelling and/or reversal of the flow of force the action of the force-producing =
=
apparatus on the rotary latch in the direction of the locking position can be cancelled. The flow of force can especially preferably be interrupted pyrotechnically. As a result of the interruption and/or reversal of the flow of force the prestressing force can be taken from the rotary latch so that it can be opened without resistance.
The flow of force is preferably interrupted by destroying the force-producing apparatus. To this end, for example, a cutting charge can be provided in the force-producing apparatus that destroys the force-producing apparatus and therefore cancels the prestressing of the rotary latch.
Additionally or alternatively, the flow of force can be interrupted by bending a spring provided in the force-producing apparatus in order to cancel the prestresses of the rotary latch in this manner.
Furthermore, the flow of force between the force-producing apparatus and the rotary latch can be interrupted or cancelled in that at least one connection between the force-producing apparatus and the device is interrupted or separated, for example, by removing a bearing bolt.
The bearing bolt can be removed by motor or manually. Furthermore, a cutting charge can also destroy or loosen an anchoring of the force-producing apparatus and as a result cancel the prestressing of the rotary latch. Upon a canceling of the flow of force the force-producing apparatus can continue to be connected to the lever or the rotary latch without, however, continuing to exert force, e.g., in the case of a spring as the force-producing element by relaxing the spring.
Another embodiment provides a means, in particular a cable, with which the flow of force between the force-producing element in the rotary latch can be reversed, e.g., by further compressing the spring.
Furthermore, it proved to be especially advantageous if the force-producing apparatus comprises at least one of the following elements: a screw head, a threaded section, a tapered, cylindrical section with a cutting charge and/or comprising a spring in order to prevent the spring from bending, it is preferably conducted in a casing or a container closed on one side.
In addition, it is advantageous for a better mounting of the force-producing element if the outside diameter of all sections on one side of the threaded section is smaller than the inside diameter of the threaded section.
=
A further embodiment of the invention provides that the locking device can be relaxed manually, by motor and/or by remote control. In this manner the emergency decoupling can be carried out by the vehicle crew from the protected area of the vehicle.
Furthermore, a mounted implement and/or vehicle of the initially cited type is suggested to solve the above task that comprises one, preferably two devices of the already described type so that the already described advantages are achieved.
It proved to be advantageous M a further embodiment of the mounted implement and/or vehicle if the mounted implement or vehicle comprises two devices and if the devices are disposed in such a manner that the middle axis of the bolts to be received in the devices are located on a straight line.
It is advantageous for a better separation of the mounted implement and the vehicle if the device is disposed on the mounted implement and/or the vehicle in such a manner that the movable holding element is disposed above the holding element fixed to the device.
It furthermore proved to be advantageous if the vehicle as well as the mounted implement comprise devices of the previously described type that can be connected by a common bolt.
In this case, if the decoupling of the device on the vehicle or on the mounted implement is not successful, the emergency decoupling can also be initiated on the other one.
According to another teaching of the invention the mounted implement and/or the vehicle can comprise an interface for the hydraulic and/or electrical supply of the mounted implement by the vehicle. These interfaces or connections can be separated during the emergency decoupling in the manner known from the prior art. Interfaces for controlling the mounted implement by the vehicle can also be provided.
In a method of the initially cited type the previous task is solved in that a locking device acting under lever force on a rotary latch is relaxed, wherein the mounted implement is decoupled from the vehicle. Consequently, a device of the type already described can be used, wherein the advantages already described result.
In another embodiment of the method the rotary latch is held in a locking position before the decoupling by a lever, in particular a bent lever. The lever strengthens the force with which the rotary latch is held in a locking position.
=
=
According to another embodiment of the invention, for the emergency decoupling the flow of force between the rotary latch and enforce-producing apparatus is interrupted or vice versa.
As a result of the interruption of the flow of force the prestressing of the rotary latch is canceled so that the vehicle and the mounted implement can be readily decoupled.
A further development of the invention suggests that in order to interrupt the flow of force the force-producing apparatus is destroyed, in particular mechanically or explosively, especially preferably pyrotechnically. The prestressing force on the rotary latch is canceled by the destruction of the force-producing apparatus so that the rotary latch can open and free the bolt.
This can take place mechanically, for example by a purposefully induced bending of a spring present in the force-producing apparatus. The force-producing apparatus can be destroyed explosively, in particular pyrotechnically by a cutting charge in the force-producing apparatus.
According to another embodiment of the invention the flow of force is interrupted and/or reversed manually, by motor and/or by remote control. If the flow of force can be interrupted or reversed by motor or by remote control, the vehicle crew can initiate, e.g., the emergency decoupling from the protected vehicle.
It furthermore proved to be advantageous from a constructive viewpoint that the rotary latch is opened by the intrinsic weight of the mounted implement and/or of the vehicle and the mounted implement is decoupled from the vehicle.
The device, the mounted implement and/or the vehicle can comprise appropriate means for carrying out the method.

Many vehicles 2, in particular work vehicles and/or military vehicles have coupling positions like the vehicle 2 shown in fig. 1 to which external mounted implements 3 of different types can be coupled to the vehicle 2. The spectrum of use and the range of functions of vehicles 2 can be flexibly adapted to different tasks by the possibility of coupling different work devices.
Uniform coupling points on the vehicle 2 are preferably used for the different mounted implements 3. In addition to purely mechanical coupling points the mounted implements and/or the vehicle can also comprise additional interfaces for the hydraulic and/or electrical supply of the mounted implement by the vehicle. Additionally or alternatively, a control interface between the mounted implement in the vehicle can also be provided, so that the mounted implement can be controlled from the vehicle.
A mounted implement 3 for groundwork or earthwork is coupled to the vehicle 2 in fig. 1.
The mounted implement 3 is a dozer blade 4. Alternatively, for example, a mine clearing device such as a mine clearing plow could be coupled to the same coupling points.
It is generally customary to dispose the mounted implements 3, as is shown in fig. 1, on the front of the vehicle 2. However, the coupling points and with them the mounted implements 3 can be disposed on the rear on the vehicle 2 or, for example, on the roof of the vehicle 2.
As a rule, coupling points comprise, in addition to the mechanical coupling points, interfaces for the electrical components and/or the hydraulic components for supplying the mounted implement and comprise control interfaces for the mounted implement 3. In addition. the mounted implements 3 can comprise additional apparatuses that expand their spectrum of functions. They can be, for example, sensors for the control and/or for the operation of the device or, however, also headlights that can additionally illuminate the working range of the mounted implement 3.
When using mounted implements 3 that work the ground such as e.g., dozer blades 4 and/or mine clearing plows, it can occur that they stall. However, the mobility of the vehicles 2 carrying them is significantly limited by stalled mounted implements 3 or a movement of the vehicles 2 is completely suppressed. In particular in the case of military vehicles 2 it is necessary for the protection of the crew to restore as rapidly as possible the mobility of the vehicles 2. This is achieved by decoupling the mounted implement 3 from the vehicle 2. The device 1 according to the invention, the mounted implement 3 according to the invention, the vehicle 2 according to the invention and the method according to the invention make possible an especially rapid and reliable emergency decoupling of the mounted implement 3 from the vehicle 2, in particular even in the case of high, unknown tension states due to a stalled mounted implement 3.
At first, a survey of the basic construction of the device 1 will be given using fig. 2 before a first embodiment is described more precisely using fig. 3 to 6, and subsequently a second embodiment will be described in detail using fig. 8 to 13. The design of the force-producing apparatus 20 constitutes the essential difference between the two embodiments.
Fig. 2 shows the device in a perspective top view. The device 1 comprises as elements essential for the invention a rotary latch 5 and a locking device 10. The rotary latch 5 comprises a first holding element 6 that can move from an open position to a locking position and a second holding element 7 fixed to the device. The movable holding element 6 is supported in the holding element 7 fixed to the device in such a manner that it can pivot via an articulation bolt 8. In fig. 2 the rotary latch 5 is in a locking position and comprises a bolt 9. The holding elements 6, 7 of the device 1 shown are constructed in the manner of a double gripping device. They have two holding surfaces.
In addition, the rotary latch 5 has a stop 30 against which the movable holding element 6 strikes in a locking position of the rotary latch 5. The stop 30 ensures that the rotary latch 5 surrounds the bolt 9 but does not clamp it.
=
The locking device 10 comprises a lever and a force-producing element 20. The force-producing element 20 acts via the lever on the movable holding element 6 and holds the rotary latch 5 in a locking position in this manner. It is possible with the lever to unlock the rotary latch 5 aside from the bolt 9 to be held by it with the aid of the force-producing element 20. The locking device 10 is disposed, as can be well-recognized in fig. 2, inside the device 1 and protected by side walls 18, 19. The side walls 18, 19 form a type of housing for the protection of the force-producing apparatus 20 and the bent lever 11. The side walls 18, 19 are also constructed as integral holding elements 7 fixed to the device.
The lever of the locking device, which lever is constructed as bent lever 11, is described in detail in the following.
The bent lever 11 is formed by two shanks 12, 13 connected in an articulated manner to one another. The shanks 12, 13 have substantially the same length. A shank 12 is connected in an articulated manner by the articulation 15 to the movable holding element 6.
The other shank 13 is connected via the articulation 16 to aa part of the device fixed to the device 1 and in the exemplary embodiment to a side wall 18, 19 that simultaneously forms an integral holding element 7 fixed to the device.
In a locking position of the rotary latch 5 the shanks 12, 13 of the bent lever are disposed almost horizontally in the device, as the figures 3, 4, 8 and 9 show. However, the bent lever can also be disposed horizontally or diagonally in the device.
A shank 13 has a U-shaped end. The other shank 12 of the bent lever 11 is received in an articulated manner in this U-shaped end. A curve stopped surface 17 for the force-producing element 20 is formed on the other shank 12 in the area of the articulation 14 with the shank.
The lever translation of the bent lever 11 is dependent on the angle A formed by the shanks 12, 13. The more the angle A approaches 180 degrees, the more the bent lever 11 strengthens the force of the force-producing element 20.
The force-producing element 20 extends in its longitudinal direction from the stop 17 on the bent lever to its fastening on the point of the device 1 that is fixed to the device. In the first exemplary embodiment shown the force-producing element 20 is screwed into the device I.
The prolongation of the longitudinal axis of the force-producing element 20 runs substantially centrally through the articulation 14, by which the two shanks 12, 13 of the bent lever II are connected to each other in an articulated manner. The longitudinal axis of the force-=
producing element 20 is additionally designed diagonally to the connection line of the two outer articulated points of the knee lever 11.
The force-producing element 20 in accordance with the embodiment of fig. 3 to 7 will be explained using the view in fig. 7.
The force-producing element 20 comprises a section 21 for attacking a tool, which section is bordered by a threaded section 22. The latter is followed by a tapered section 23 with a cutting charge 24. The tapered section 23 borders a wider section 25 before another tapered section 26 closes the bolt-like element of the force-producing apparatus 20.
The last-cited, tapered section 26 serves to receive a spring 27. The spring 27 is guided in a casing 28 whose movement is guided by the wider section 25. The casing 28 serves for protection against bending of the spring 27. In the exemplary embodiment the casing 28 is closed on one side and therefore constructed like a container. In addition, the outside diameter of the casing is less than the inside diameter of the threaded section so that the force-producing element can be introduced from the outside of the device into the device and be screwed.
In the following the functioning of the device 1 during the emergency decoupling is described using fig. 3 to 6.
As can be seen in the fig. 3 and 4 the device 1 is in a coupled state in which the rotary latch 5 surrounds the bolt 9. The movable holding element 6 is held in the locking position via the strengthening of the force of the bent lever 11 by the force-producing element 20. The force producing element 20 is screwed into a section of the device 1 which section is fixed to the device and presses with the spring 27 against the stop 17 of the bent lever 11.
If the device 1 is to be decoupled in an emergency, the cutting charge 24 in the force-producing element 20 can be ignited, for example, by remote control from the interior of the vehicle 2. This separates the tapered section 23, as can be seen in fig. 5 and 6, and the force-producing element 20 is destroyed as a result. This interrupts the flow of force via the bent lever 11 to the movable holding element 6. As a consequence, the rotary latch 5 is no longer prestressed and is easy to open. In the exemplary embodiment the opening of the rotary latch takes place due to the intrinsic weight of the mounted implement 3 and the mounted implement 3 slides off from the bolt 9. This cancels the coupling between vehicle 2 and mounted implement 3.
=
In the following a second exemplary embodiment of the invention will be described using fig.
8 to 11. The second exemplary embodiment differs substantially from the first exemplary embodiment by the force-producing element 20 and its connection to the device 1 and to the bent lever 11. The force-producing element 20 is designed as spring 29, as can be readily recognized in the figures. The spring 29 is constructed as a pressure spring.
It is connected by one end to a part of the device 1 fixed to the device and attacks with its other end in the area of the middle articulation 14 between the shanks 12, 13 of the bent lever 11. In this manner the spring 29 prestresses the rotary latch 5 via the bent lever 11 in its locking position.
The second exemplary embodiment also comprises, as can be seen in the fig. 8 to 11, a stop 30 that ensures that the bolt 9 is not clamped in the locking position of the rotary latch 5 by it.
In this manner a simple mounting of a mounted implement 3 on a vehicle 2 is ensured by inserting and withdrawing the bolt 9. Alternatively, a stop 30 can also be provided on the bent lever 11 that also has the result that the bolt 9 is not clamped.
The device according to the second exemplary embodiment can be opened for an emergency in different ways.
For an emergency opening, on the one hand the force-producing element 20, in the present case the spring 29, can be loosened on one end from the device 1, for example, by withdrawing a bearing bolt 31, 32 with which the force-producing element 20 is connected to the device 1. The bearing bolt 32 is preferably removed, that connects the force-producing element 20 on the end facing away from the bent lever 11 to the device 1. In this manner the flow of force from the force-producing element 20 to the rotary latch 5 is cancelled. During the loosening of the bearing bolt 31 the flow of force would be interrupted.
The bearing bolts 31, 32 can be removed manually or by motor for the emergency opening.
For better accessibility to the bearing bolts 31, 32 the side walls 18, 19 in the area of the bearing bolts 31, 32 can comprise a perforation. In fig. 8 the perforation is designed as hole 33.
On the other hand, for the emergency opening the spring 29 in the force-producing element 20 can be compressed to such an extent that the rotary latch 5 opens, as shown in fig. 10 and 11. For the compression of the spring 29, for example, a traction means (not shown) that attacks the bent lever 11 and a section running parallel to the force-producing element 20 can =
be used. By pulling on this traction means, e.g., a cable, the pressure spring 29 of the force-producing element 20 can be further tightened and therefore the flow of force between it and the bent lever 11 and therefore the rotary latch 5 can be reversed and therefore the rotary latch 5 can be opened. The pulling on the traction means can take place either, for example, with the aid of an electrical motor or, however, as an alternative, even manually in order to initiate the emergency decoupling. Therefore, a simple and reliable emergency decoupling is given.
The previously described device 1 as well as the previously described mounted implement 3 and the previously described vehicle 2 and the previously described method for the coupling and emergency decoupling of a mounted implement 3 from a vehicle 2 are distinguished in particular in that they ensure a simple and reliable emergency decoupling requiring only little force by opening the rotary latch 5.
