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

15th

20th

There are clutches of the type mentioned in various designs for a long time * It is common that they are relative are complicated and expensive. The couplings are relatively complicated because they are connected to a large number of different types of conventional Couplings should be able to be coupled. The main disadvantage is the great height that the 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.

According to Figures 1-3 contains a in a coupling head 1 horizontal mounted bolt 2 a horizontally movable pawl 3. In addition, a horizontally movable button 4 is in the coupling head 1 to an im Coupling head 1 fixed bolt 4 'mounted. The bolt 2 is on the Pawl 3 pressed by a spring 5 in the coupling-ready or coupled position. When unlocking with a button on the 3 hinged tension element 6 is first the pawl 3 so in a The elongated hole 3a engages in the pawl 3 and is firmly attached to the bolt Bolt 2a rotated so that the pawl 3 comes out of engagement with the opposite pawl 3 'in the mating coupling head 1'. As soon as the latch 3 rests against a connection 7 located on the bolt 2, the bolt 2 with the tension element 6 is withdrawn against the force of the spring 5. Included the pawl 3 is displaced by the resulting torque so that a detent 8 is printed on the pawl 3 towards the button 4. Of the from the profile of the mating coupling head 1 'against the force of the spring Pressed button 4 pushes at the end of the unlocking stroke over the contour 9 on button 4, the pawl 3 to the side that this is at the end of the stroke can hook with the button 4 or snap behind the button 4, as indicated by dashed lines by 3 ". After the Separating the coupling, the spring 10 pushes the button 4 into the free coupling profile, the hooked contour between the button 4 and

if the pawl 3 is formed in several parts and the individual parts are biased by additional springs so that the above-described Function is fulfilled.

The case described in is only an example

according to the invention, wherein relatively few items are required. Instead of the pivoting of the locking gear parts and 4 about vertical bolts 2a and 4 ^{1, there} can also be equivalent locking gear parts which are arranged displaceably in horizontal housing guides of the coupling heads. According to the invention, the bolt 2 or the pawl 3 is connected to the mouthpiece of a line coupling (not shown), wherein

when the mouthpiece 16 is provided with the pawl 3, either an telescopic solution with a stroke corresponding to the stroke of the pawl 3 is provided or springs are deflected accordingly to ensure the tightness between two mouthpieces. A corresponding mouthpiece 16 'is located in the mating coupling head I ¹ .

With this solution there is also the possibility of providing contours in the contact surfaces between the bolt 2 and the opposite bolt 2 'in the mating coupling head I ¹ , which allow a manual half-shell coupling to be connected to the mouthpiece 16 of the line coupling.

The locking 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 slide 20 in the vertical, the according to the invention is provided with a mouthpiece 21 of a line coupling 22 ^ 5.

The automatic coupling points in a cavity of the coupling head (1) a horizontally movable bolt (2) and an associated, horizontally movable bolt gear (3, 4). The dog piece (16) a line coupling can be connected to the bolt (2) or a part (3) of the bolt mechanism (3, 4), which acts against spring forces (5,10,13,15) is movable The locking mechanism consists either of horizontally adjustable slide parts or of latch or key-like parts that are about vertical axes (2a, 4 ') are held pivotable. A mutual latching can be achieved by spring-elastic snap effects. The little claw of the Coupling head (1) can be designed in such a way that it can be coupled to a conventional coupling head that does not have line couplings having.
