Abstract

Within an automatic, rigid coupling having a bolt (2) which can be moved horizontally in a cavity of the coupling head (1) and having an associated, horizontally movable bolt transmission (3, 4), the mouthpiece (16) of a line coupling is connected to the bolt (2) or to a part (3) of the bolt transmission (3, 4) which can be moved counter to spring forces (5, 10, 13, 15). The bolt transmission consists either of slide parts which can be displaced in the horizontal direction or of latch-like or key-like parts which are held so as to be swivellable about approximately vertical axes (2a, 4'). Mutual latching can be brought about by spring-elastic snap-in effects. The small claw of the coupling head (1) can be constructed in such a way that it can be coupled to a conventional coupling head which does not have any line couplings. <IMAGE>

Description

Automatic coupling for rail vehicles

The invention relates to an automatic coupling for rail vehicles according to the features of the preamble of claim 1.

There are clutches of the type mentioned in various
Designs have long been known, it is agreed that they are relatively complicated and expensive. The couplings are relatively complicated,
because they use a variety of different conventional
Couplings should be able to be coupled. The main disadvantage is the large one
Height that the well-known coupling heads have in order for everyone
To be prepared for coupling situations.

25th

The object of the invention is a coupling of the type mentioned at the beginning indicate, which has a low overall height to save material and is particularly simple with little space requirement.

According to the invention, the object is achieved with the characterizing features of Claim 1 solved.

Advantageous designs and developments result from the
Features of the subclaims and the following description.

The invention will be explained in more detail with reference to exemplary embodiments described and explained.

Figure 1 two coupling heads coupled together, shown broken off in plan view,

FIG. 2 shows a section along the lines II-II in FIG. 1 in

broken representation,

Figure 3 shows a locking mechanism according to the invention in plan view and

FIG. 4 shows a conventional coupling in a side view, the known latch according to the invention with the mouthpiece a line coupling is provided.

According to FIGS. 1-3, a bolt 2 mounted horizontally in a coupling head 1 contains a horizontally movable pawl 3. In addition, a horizontally movable button 4 is mounted ^{in the coupling head 1 around a bolt 4 1 fixed in the coupling head 1.} The bolt 2 is pressed via the pawl 3 by a spring 5 into the ready-to-couple or coupled position. When unlocking by a pulling element 6 hinged to the pawl 3, the pawl 3 is first rotated around a bolt 2a that engages in an elongated hole 3a in the pawl 3 and is firmly attached to the bolt, that the pawl 3 with the opposite pawl 3 'in the mating coupling head I. ¹ comes out of engagement. As soon as the pawl 3 rests against a connection 7 located on the bolt 2, the bolt 2 with the tension element 6 is withdrawn against the force of the spring 5. The pawl 3 is shifted by the resulting torque in such a way that a detent 8 on the pawl 3 is pressed towards the button 4. The button 4 pushed in by the profile of the mating coupling head 1 'against the force of the spring ^ow pushes the pawl 3 to the side at the end of the unlocking stroke over the contour 9 on the button 4 so that it hooks with the button 4 or behind at the end of the stroke can snap the button 4, as ^{indicated by dashed lines 3 1} '. After this

When the clutch is disconnected, the spring 10 pushes the button 4 into the free position 35

Coupling profile, the hooked contour between the button 4 and the KlinkZe 3 is released so that the bolt 2 by the force of

Spring 5 can be pushed back into the starting position. 5

For coupling with couplings that do not have such pawls 3 are equipped, to secure the position in the coupled state either a manually operated, in the horizontal Slidable pin 11 inserted, or there is an additional horizontally movable lock 12, here e.g. on the pawl 3 provided, possibly by a spring 13 supported on the pushbutton 4 in the locking position relative to the stop 14 on Coupling head 1 is pressed and when the profile of the counter coupling head pressing the button 4 this after disconnection · * · ° the clutch releases by the spring 15 between the lock 12 and the pawl 3 is pressed into the unlocked position, so that the locking system is ready for coupling again.

The function of the lock 12 can be performed by all previously known in Willison clutches, in the vertical movable locks of the bolt 2 can be replaced in the coupled state, the parts moved by gravity in the known systems according to the invention moved horizontally by spring forces.

The function of the detent 8 of the pawl 3 can also be used when the pawl 3 is constructed in several parts and the individual parts are biased by additional springs so that the above-described Function is fulfilled.

The case described above is only an exemplary embodiment according to the invention, with relatively few items being required. Instead of the pivoting of the locking gear parts and 4 to vertical bolts 2a and 4 'can also be designed equivalent, in horizontal housing guides of the coupling heads Slidably arranged locking gear parts be available. The latch 2 or the pawl 3 is, according to the invention, with the mouthpiece 16

connected to a line coupling not shown, in which case, when the mouthpiece 16 is provided with the pawl 3, either a telescopic Lb'sung with a stroke corresponding to the stroke of the pawl 3 is provided or springs are correspondingly strongly deflected to ensure the tightness between two mouthpieces to ensure. A corresponding mouthpiece 16 'is located in the mating coupling head I ¹ .

With this solution, there is also the option of in the contact areas between the bolt 2 and the opposite bolt 2 'in the mating coupling head 1 * to provide contours that allow a manual half-shell coupling with the mouthpiece 16 of the line coupling connect to.

D _as latch system according to the invention advantageously allows a particularly flat design. Should it be necessary to couple such a coupling device designed as a rigid coupling with a non-rigid coupling, then it must be ensured that it does not come loose ^{even with a corresponding relative vertical displacement between the two coupling heads 1 and I 1.} For this purpose, it is advisable to make the small claw 18 of the coupling head 1 (Fig.l and 2) so high that the relative displacements between the coupling heads do not lead to the coupling being separated.

Around the rest of the coupling head and thus the latch gear system According to the invention, to keep it low, in this case in the upper and optionally in the lower area of the small claw 18 a Provided under the bolt 2 lying head contour 19, the front contour of which corresponds to approximately half the return of the bolt 2, so that two such couplings can engage and disengage with one another, however, a coupling with bolt 3 at the very front remains coupled.

Fig.4 still shows the side view of a conventional coupling which only shows the bolt 20, which is displaceable in the vertical direction and which, according to the invention, has a mouthpiece 21 of a line coupling 22 is provided.
