Definitions
- the present invention relates to an automatic train coupler, in particular for a freight car of a rail vehicle, according to the preamble of claim 1 and a method for uncoupling such an automatic train coupler according to the preamble of claim 15.
- generic automatic train couplings which have a coupling head with a coupling housing and a coupling lock with a lock.
- the coupling lock is designed as a rotary lock with a coupling eyelet and a frog, the frog being rotatable about a main axis between a coupled position and an uncoupled position, and the coupling eyelet being connected to the frog with a first end rotatable about a coupling eyelet axis and a second free end having.
- the frog has a mouth for receiving a corresponding second end of a coupling eyelet of an opposite coupling head.
- a spring accumulator is assigned to the frog.
- the frog can be rotated from the coupled position to the uncoupled position against the force of the spring accumulator and from the uncoupled position to the coupled position by the force of the spring accumulator.
- the uncoupled position is also referred to as the ready-to-couple position, since in this position the train couplings of the two cars can be moved towards one another and coupled. If necessary, the coupling closure or its heart can also be rotated into a position that is overextended in relation to the coupling-ready position, ie opened more than necessary. In this stalled position, the spring accumulator is tensioned to the maximum.
- This stalled position is also a ready-to-couple or uncoupled position within the meaning of the present invention. Furthermore, such a coupling-ready or uncoupled position is also referred to as a waiting position.
- the locking device which holds the coupling lock in the appropriate position or releases it for the transition to a different position by turning the frog, has, for example, a plunger that can be displaced against a spring force in the coupling direction of the train coupling and a ratchet rod that can be displaced transversely or diagonally to the coupling direction.
- the pawl rod is articulated to the frog and can be displaced by the frog when it rotates from the coupled position to the uncoupled position into a latching position in which the pawl rod prevents the frog from rotating back, i.e. in the direction from the uncoupled position to the coupled position .
- the plunger in turn, is movable between a first position and a second position.
- the plunger In the first position, in which the plunger is displaced against the spring force, the plunger blocks the ratchet rod in the detent position and in the second position, into which the plunger is displaced from the first position by the spring force, the plunger releases the ratchet rod from the detent position.
- the function of the generic automatic train coupling is as follows: Two opposite coupling heads on two vehicles to be coupled to each other are locked together by inserting the second end of the respective coupling eyelet into the mouth of the frog of the other coupling head and holding it positively by turning the frog there becomes. This mechanically couples the two vehicles together.
- the two coupling locks are only loaded by tensile forces, which are distributed evenly over both coupling eyes within the parallelogram formed by the coupling eyes and frogs.
- Compressive forces on the other hand, are transmitted by a special profile on the front of the coupling head housing, the profile generally comprising a cone and a funnel, which is also advantageous in the present invention, which are surrounded by a wide, particularly flat, end face.
- the profile can be formed by a separate face plate attached to the front of the coupler head housing.
- the profile can form sliding and centering surfaces with the cone and funnel and, in particular, determine the gripping area in lateral, vertical and angular offset. When the coupling heads meet, they center and slide into each other.
- an uncoupling device rotates both coupling locks, i.e. the two frogs, against the force of the spring accumulators until the coupling eyes slide out of the mouths of the frogs.
- the twisting crossing frogs are intended to move the ratchet rods to such an extent that when the vehicles are separated, the frogs are prevented from turning back from the stalled position beyond the ready-to-couple position by bringing the ratchet rods into their latching positions.
- Uncoupling devices are known in different designs.
- manually operable, mechanical uncoupling devices have levers, cables and/or chain hoists, which act on different types of bolts and cancel the bolted position when actuated.
- Automated uncoupling devices include a pneumatic cylinder or an electric motor as a drive, in particular a linear actuator, which the Train coupling uncoupled.
- DE 29 23 195 C2 discloses a remote-controlled uncoupling device for a central buffer coupling of a rail vehicle, in which an electric motor uses a cam disk to actuate a lever connected non-rotatably to the main pin in order to rotate the frog from the coupled position to the uncoupled position.
- DE 40 13 521 A1 discloses a coupling and decoupling device for an electrical cable coupling and a mechanical coupling with a common rotary drive.
- EP 3 470 295 A1 discloses an electric linear actuator which acts on the main bolt via a lever.
- the known automated uncoupling devices require a relatively large amount of space and are arranged on the outside of the automatic train coupling outside of the coupling head housing.
- housings can be provided which shield the uncoupling devices from the environment.
- a disadvantage of the known embodiments is the structural complexity associated with these housings and the comparatively large installation space that is required as a result.
- a further disadvantage of the known automatic train couplers is that after uncoupling with the uncoupling device, the frog can be unintentionally twisted into its coupled position if the corresponding rail vehicle, which has the automatic train coupler, is being moved in shunting operation. For example, when the rail vehicle is pushed over a hump, there is a risk that the automatic train coupling that has just been disengaged will be re-engaged before the rail vehicle drives onto the wagon provided in the siding. Accidental engagement requires the clutch to be disengaged again, which takes additional time and interferes with maneuvering.
- the present invention is based on the object of providing an automatic train coupling, in particular for a freight car of a rail vehicle, for example of the embodiment illustrated above improve and specify a method for uncoupling an automatic train coupling, in which the aforementioned disadvantages are avoided.
- the automatic train coupling according to the invention which is designed in particular as an automatic train coupling of a freight car of a rail vehicle, has a coupling head that includes a coupling head housing and a coupling lock with a lock.
- Locking means that the coupling closure can be locked in a rotationally fixed manner at least in one position, as follows from the following.
- the coupling lock is designed as a rotating lock with a coupling eyelet and a frog, the frog being rotatable about a main axis of rotation between a coupled position and an uncoupled position.
- the coupling eyelet is connected to the frog with a first end such that it can rotate about a coupling eyelet axis and has a second free end.
- the frog has a mouth which is arranged to receive a second end of a coupling eyelet of an opposite coupling head.
- an electrically, hydraulically or pneumatically actuated uncoupling device which comprises an electric motor, hydraulic motor or pneumatic motor, which is at least indirectly connected to the frog via a drive connection in order to rotate the frog from the coupled position into the uncoupled position. With the locking, the frog can be held against rotation, particularly in the uncoupled position, the so-called ready-to-couple position.
- the uncoupling device has a blocking position in which it blocks rotation of the frog from the uncoupled position into the coupled position via the drive connection, with a control device being provided with which the uncoupling device can be controlled in order to keep it permanently in the blocked position for a period of time to keep.
- the duration of the period of time can be determined, for example, by active actuation, in particular by means of a switch, in that, for example, holding in the locked position is ended when the vehicle driver releases it.
- a predetermined period of time could also be selected, which is then ended automatically.
- the uncoupling device according to the invention therefore acts through the motor contained in it and is to be distinguished from the previously mentioned locking mechanism, which acts purely mechanically by means of two automatic train couplings moving against one another. Rather, the electrically, hydraulically or pneumatically actuated uncoupling device is provided in addition to the mechanical locking.
- the uncoupling device is preferably either arranged completely inside the coupling head housing, or the uncoupling device is arranged completely inside the coupling head housing and a coupling rod adjoining the coupling head housing, i.e. in a space which is either enclosed solely by the coupling head housing or by the coupling head housing together with a corresponding area the coupling rod is enclosed.
- parts of the electrically, hydraulically or pneumatically actuated uncoupling device are arranged outside the coupling head housing and outside the coupling rod, with other parts of the uncoupling device preferably being arranged inside the coupling head housing and/or the coupling rod, for example the motor and in particular the strain wave gear and/or bevel gear explained below.
- the parts arranged outside of the coupling head housing can be enclosed by an additional housing.
- the electrically, hydraulically or pneumatically actuated uncoupling device can be designed to be particularly compact if the motor has an output axis of rotation which is arranged at least essentially radially to the main axis.
- the output axis of rotation therefore advantageously points in the direction of the main axis or intersects the main axis or at least one main pin which can be rotated about the main axis and which is connected to the frog in a rotationally fixed manner.
- the electrically, hydraulically or pneumatically actuated uncoupling device Compared to an engine output axis of rotation, which is arranged skewed or tangential to such a main pin or to the main axis, the electrically, hydraulically or pneumatically actuated uncoupling device requires a much narrower installation space, which extends with its longitudinal extent in the direction of the longitudinal axis of the coupling rod or the longitudinal axis of the coupling head housing and is therefore light can be accommodated within the coupling head housing and, if necessary, the adjacent area of the coupling rod.
- an angular gear is provided in the drive connection between the motor, in particular the electric motor, and the frog.
- Such an angular gear can, for example, by a drive pinion and a toothed engagement with it Crown gear are formed, the axis of rotation of which is parallel to the main axis.
- the drive pinion can be provided on the output axis of rotation or on an output shaft of the motor, in particular the electric motor, rotating around the output axis of rotation, or it can be arranged coaxially with it and be in driving connection with the output shaft of the motor.
- the drive pinion can also be designed as a bevel gear that meshes with another bevel gear instead of the crown gear.
- the bevel gear is connected to the frog via a one-piece or multi-piece articulated lever.
- a driver can be provided on the bevel gear output, for example in the form of a bolt on a disc, which takes the articulated lever with it when the frog is rotated from the coupled position to the uncoupled position and prevents the bevel gear output from rotating in the allows opposite direction without entrainment of the articulated lever.
- the angular gear is connected to the frog via an articulated lever, which is at least in two parts, comprising a first lever part, which is articulated to the frog, and a second lever part, which is articulated to the first lever part and articulated to an angular gear output, wherein the axes of rotation of said articulated joints are parallel to the main axis.
- the angle gear output can be formed, for example, by a rotary lever that extends radially to an angle gear output axis of rotation.
- a bevel gear output is essentially spoke-shaped.
- a disc-shaped or circular angular gear output or other shapes can also be considered.
- a reduction gear can be provided between the bevel gear and the motor, advantageously with a coaxial arrangement of its input and output.
- the bevel gear can be designed, for example, as a planetary gear or eccentric gear, in particular in the form of a strain wave gear.
- a differential gear can also be considered, for example.
- the output of this reduction gear is then formed in particular by the said drive pinion, which represents the input to the bevel gear.
- the reduction gear in particular in the form of the strain wave gear, can then be arranged coaxially to the motor or to its output axis of rotation.
- the bevel gear can preferably have a further reduction in order to further reduce the speed in the direction of the drive power flow behind the bevel gear and preferably at the same time to increase the transmitted torque. In this way, a particularly high torque can be achieved on the frog for rotating the frog from its coupled position into the uncoupled position.
- the harmonic drive and/or the bevel gear can be carried, in particular exclusively, by the motor or by a console that carries the motor and is in particular plate-shaped.
- the bevel gear output can preferably be rotated about an bevel gear output axis of rotation between a zero position and a release position. In the zero position, the bevel gear output enables the frog to be rotated between the coupled position and the uncoupled position without being hindered by the bevel gear output. When turning the bevel gear output from the zero position into the release position, the bevel gear output drives the frog so that it rotates from the coupled position to the uncoupled position.
- the length of the articulated lever in particular the lengths of the first lever part and the second lever part, are therefore preferably chosen such that the frog can be rotated from the uncoupled position into the coupled position and the bevel gear output remains in the zero position.
- the arc that the axis of rotation of the articulated connection of the second lever part on the bevel gear output sweeps over when rotating the bevel gear output from the zero position to the release position can be less than or equal to the combined lengths of the first lever part and the second lever part.
- the bevel gear is connected at least indirectly via a wheel drive to a main pin, which is connected to the frog in a drive connection.
- the drive connection can be a non-rotatable connection on one side with a freewheel acting in the opposite direction, so that the frog can be rotated from the coupled position to the uncoupled position with the electrically, hydraulically or pneumatically actuated uncoupling device or with its bevel gear, but in the opposite direction
- Actuation of the bevel gear without torque transmission to the frog is possible in order to enable the frog to be turned back from the uncoupled position to the coupled position, with the turning back then taking place in the conventional manner via the coupling lock or by moving two automatic train couplings together.
- a unidirectional driver is provided in the drive connection between the angular gear and the frog or the main pin, which transmits the uncoupling movement of the uncoupling device to the frog and an opposite movement of the uncoupling device does not affect the Heart passes on.
- the bevel gear has an bevel gear output that can be rotated about a bevel gear output axis of rotation, which is parallel to the main axis and on which a first spur gear is arranged, which meshes with a second spur gear or a spur gear segment which is in a driving connection with the main bolt, the bevel gear output being rotatable between a zero position and a release position.
- the frog when the bevel gear output is rotated from the zero position to the release position, the frog is rotated from its coupled position to the uncoupled position, but when the bevel gear output is rotated back from its release position to the zero position, the frog is rotated from the uncoupled position to the coupled position only released without a corresponding twisting of the frog immediately taking place.
- a hand-operated device with which the frog can be brought manually into the uncoupled position and/or the bevel gear output into the zero position.
- the frog can be brought manually into the uncoupled position and/or the bevel gear output into the zero position.
- the automatic train coupler can be uncoupled by turning the frog into the uncoupled position.
- the second spur gear or spur gear segment has a driver that acts on one side of a lever of the manual operating device, which acts on the main bolt, in the sense of rotating the frog from the coupled position to the uncoupled position.
- the uncoupling device can preferably be actuated independently of the position of the frog, and in particular the bevel gear output can be rotated with the motor about the bevel gear output axis of rotation both in the coupled position and in the uncoupled position of the frog.
- the position of the uncoupling device in particular of the bevel gear output and/or the articulated lever and/or the second spur gear or spur gear segment, can preferably be detected with a sensor in order to to be able to monitor certain positions of the uncoupling device and/or to be able to control them in a better targeted manner.
- the automatic train coupling can be provided with a locking device which, in particular, comprises the illustrated ratchet rod and the plunger and works as described at the outset.
- a rail vehicle according to the invention has a corresponding automatic train coupling of the type shown.
- a method for uncoupling an automatic train coupling provides that the frog is moved from the coupled position to the uncoupled position via the drive connection between the electrically, hydraulically or pneumatically actuated uncoupling device and the frog by driving the motor with the electrically, hydraulically or pneumatically actuated uncoupling device is twisted.
- the uncoupling device In a preselectable operating mode, the uncoupling device is held in the blocked position and thus the uncoupling device blocks rotation of the frog from the uncoupled position into the coupled position.
- the automatic train coupling can preferably be operated in two different operating modes, with a first operating mode being adjustable with the control device, in which the uncoupling device, immediately after rotating the frog with the uncoupling device from the coupled into the uncoupled position, rotates the frog from the uncoupled position into releases the coupled position again, in particular by rotating the bevel gear output from the release position to the zero position, and a second operating mode can be set with the control device, in which the uncoupling device is held in the locked position, as explained.
- a first operating mode being adjustable with the control device, in which the uncoupling device, immediately after rotating the frog with the uncoupling device from the coupled into the uncoupled position, rotates the frog from the uncoupled position into releases the coupled position again, in particular by rotating the bevel gear output from the release position to the zero position
- a second operating mode can be set with the control device, in which the uncoupling device is held in the locked position, as explained.

- FIG. 1 An uncoupled position of the coupling head 1 or the coupling closure 3 is shown in FIG.
- Such an uncoupled position which is also referred to as a position ready for coupling, can also be the above-mentioned engaged position.
- FIG. 2 shows that all components of the coupling lock 3 are accommodated within the coupling head housing 2 and that the coupling rod 10 is connected to the coupling head housing 2 in the longitudinal direction of the train coupling, which, in addition to the coupling head housing 2, forms part of the electrically actuated uncoupling device 11 , Here the electric motor 12 receives.
- FIG. 3 shows a horizontal section through the coupling head housing 2 and the adjoining area of the coupling rod 10.

- FIG. 4 shows the arrangement from FIG. 3 again in a vertical section, but here without the coupling rod 10, which adjoins the coupling head housing 2 in the axial direction.
- the electric motor 12 in the drive connection to the frog 6 is initially followed by a strain wave gear (or generally a reduction gear, in particular an eccentric gear or differential gear) 25, which carries a drive pinion 13 on the output side coaxially with the output axis of rotation 12.1 of the electric motor meshes with a crown wheel 14 revolving around a vertical axis of rotation 14.1 in order to drive the crown wheel 14.

- FIGS. 6 shows the frog 6 in the uncoupled position, the bevel gear output 15.1, which is formed by the rotary lever 17, is in its so-called zero position, in which it does not prevent the frog 6 from rotating about the main axis 7.
- the first lever part 16.1 and the second lever part 16.2 are folded in or against one another, that is to say they enclose a comparatively acute angle between them.
- bevel gear output 15.1 can remain in its zero position and the increasing distance between the connecting joint of articulated lever 16 on frog 6 and the The connecting joint of the articulated lever 16 on the bevel gear output 15.1 is bridged by unfolding the first lever part 16.1 and the second lever part 16.2. Accordingly, in the coupled position of the frog 6, the first lever part 16.1 and the second lever part 16.2 extend relatively linearly to one another.
- the bevel gear output 15.1 or the rotary lever 17 is driven into the release position shown in Figure 8 twisted with the electric motor 12. During this twisting, the rotary lever 17 pulls on the articulated lever 16 on the frog 6, so that the frog is twisted into the uncoupled position.

- a one-sided torque transmission can be achieved by a freewheel.
- this torque transmission is achieved by a driver 32, which is stationarily connected to the spur gear segment 30 (or a corresponding second spur gear) and takes the lever 33 of the manual operating device 20 with it when the bevel gear output 15.1 is rotated from its neutral position into the release position.
- the lever 33 is connected to the main pin 19 in a correspondingly non-rotatable manner. In principle, however, it would also be possible to connect this lever 33 or another lever, which is carried along by the driver 32, to the frog e.
- the bevel gear 15 can easily be turned back without the frog 6 being moved into its coupled position at the same time.
- the frog thus remains in the uncoupled position until the coupling lock 3 is brought into the coupled position by moving against an opposite train coupling or an opposite same coupling lock.
