r, 6 The present invention relates to rail transport, more precisely on devices for the automatic connection of air and electrical lines of the railway vehicles.

Devices are known for the automatic connection of air and electrical lines of the railway vehicles, which contain a contact socket which is kinematically connected to the automatic coupling. The kinematic connection is established by means of a lever, the axis of which is attached to the housing of the automatic clutch. _{The contact socket 9} is hinged to one lever arm, while the other is braced against a spring located in the housing of the automatic clutch. When coupling the automatic couplings, the spring is compressed and actuates the lever that pushes the contact socket out onto the line of action. The spring mentioned simultaneously brings about the pressing of the connected cans against one another.

To ensure the hermetic connection of the air lines and the reliable connection of the electrical ones A strong spring must be used for contacts, which prevents the coupling of the automatic couplings from being soldered, while the force of the compressed air, which tends to spread the contact sockets apart, acts on the heads of the self-

make clutches is transmitted and an uneven Causes wear and tear on their work surfaces.

Devices for connection are also generally known of air and electrical lines, where the ■ hermetic connection of air lines and reliable Connection of the electrical contacts of compressed air equipment is guaranteed. These facilities, which are based on the use of several compressed air cylinders and pistons, require very precise machining of their individual parts and are not reliable, and all the more so when the effect of high impact forces when connecting the contact sockets and the influence of temperature changes the outside air is taken into account (at low temperatures the cuffs lose their flexibility and the lubricant freezes).

In addition, the well-known contact sockets with a pneumatic seal call the connection point by having the effect the spreading force of the compressed air is transmitted to the heads of the coupled automatic couplings, one uneven wear of the working surface of the automatic clutch during operation «

The aim of the present invention is to eliminate the drawbacks mentioned.

The invention is based on the object of providing a device for connecting air and electrical lines

909841/1018

genes to create such a hermetic and reliable Connection of the contact sockets would ensure the spreading force exerted by the compressed air is generated on the heads of the automatic couplings will not be transferred.

This object is achieved in that in the device for the automatic connection of the air and electrical lines of the railway vehicles, which have a contact box and contains a mechanism that this kinema- with the automatic coupling for -HerVorschieben on the line of action. table connects, on the contact surface of the can a centering pin and an opening for the centering pin of the adjacent Can are present; according to the invention is at the contact socket a pawl arranged, which cooperates with the centering pin of the adjacent can and locked in the State is held in place by a plunger that is hinged to the mechanism that holds the can on the Line of action brings while between the contact socket and a device is arranged on the plunger, the latter at a certain distance from the pawl when disconnected holding cans attached.

Appropriately, the device that the plunger at a certain distance from the pawl when unconnected holds adjacent cans, executed in the form of an angle lever, the pivot axis of which is attached to the plunger, / - 3er one arm braces itself against the contact socket while moving

the other is opposite the opening for the passage of the centering pin of the adjacent can.

This design of the device mentioned ensures the locking of the pawl only after the coupling Contact sockets.

No less useful is the arrangement of the plunger between the air lines, which serve as guides for. serve the same. This arrangement of the plunger allows the To make construction even more compact.

Appropriately, the contacts of the electrical Lines attached to the tappet. This arrangement of the contacts of the electrical lines ensures a reliable one Connection of contacts after connection of air lines:

For automatic opening of the coupling cock of the air line after connecting the air lines, the dumbbell must of the rope, which serves as the drive for opening the coupling valve of the air line, attached to the plunger and a stop should be provided on it to act on the rope of the adjacent can

This attachment of the cable jacket to the ram is guaranteed opening of the coupling tap only after a connection of the air ducts.

When coupling the adjacent automatic couplings bring the fervors chi elenden mechanisms 2 the adjacent Contact boxes 1 on the engagement line 3. Here, the centering pins 15 go into the corresponding ones openings 16 (Fig. 9 »10) in the plates 10 of the adjacent Cans 1 in.

Then begin the tapered ends of the cylindrical file of the pin 15 on the arms 29 of the angle lever of the adjacent cans 1 to act. At the same time, the pins 15 act on the pawls 20 of the adjacent cans 1 a, turning them on the axes 19.

As soon as the centering pin 15 is in their corresponding openings 16 of the adjacent cans 1 have fully entered, the plates 10 of these cans will have connected at their contact surfaces 13, the air ducts 11 and 12 of the adjacent cans 1 join together. The pawls 20 lower under the action of their own weight and go with their projections 21 into the recesses on the centering pins 15 of the adjacent cans 1. The angle levers 26 pivot under the action of the centering pins 15 of the adjacent cans 1 on their axes 2 ?, and their arms 28 protrude from behind the stop into the

tifungen the plate 10 and are stored freely in the wells 53 of the plate 10. Since the arms 28 of the angle lever 26 will not be bracing against the plates 10, so go

the plungers 8 under the action of the mechanisms 2 for advancing of the contact sockets 1 to the flats IO of their contact sockets 1. Here go the L-shaped strips 24, which are attached to the tappets 8, with their ends 54 in the spaces between the projections 22 of the pawls 20 and the lugs 23 of the plates 10 into it. To this In this way, the pawls 20 will be blocked by the strips 24- and the ones produced by compressed air spreading them apart Forces that are effective between the connected air lines are only transmitted by the centering pins 15t to the pawls 20 and the strips 24 and not on the lever 4 and thus not transferred to the housing of the automatic clutch, which would cause wear on the heads of the automatic Couplings reduced

When the plunger 8 approaches the plates 10 of the contact boxes 1, the electrical contacts are connected 25 of the adjacent cans 1.

At the same time, when the ram 8 approaches the plates 10, the stops 51 of the contact sockets that are in contact with each other act 1 (FIG. 11) on the protruding end pieces 48 of the ropes 46.

These stops go into the corresponding openings 43 in the plates 10 of the adjacent cans 1 and press the end pieces 48 into the dumbbell 47. This shifts the page 46 in the jackets 47, and the

The electrical contacts 25 diverge, whereby they separate the electrical lines. When uncoupling the self-acting couplings, the coupling valve 34 is simultaneously closed by turning the shaft 35 by hand.In doing so, the lever 37, acting on the cup 39, compresses the spring 40, and the seal 41 locks the cup 39 «

With the departure of the plunger 8 from the plate 10 goes the stop 44 of the adjacent can 1 away from the end piece 48. the slide 45 acts under the action of the spring 58, by returning to the starting position, on the end piece 49 of the rope 46, so that it presses it into the jacket 47. Here, the end piece 38 emerges from the other end dee jacket 47 out, and the whole mechanism 38 for Opening the clutch cock assumes the starting position.
