DE591349C - Central buffer coupling with a coupling rod that carries the air duct coupling - Google Patents

Description

The invention relates to a central buffer coupling for railway vehicles with a funnel-shaped buffer and one in this through one from the side of the vehicle forth movable and secured in the ready position vertical bolts held symmetrical coupling rod, the at the same time carries the coupling for the air hose line. With the known Couplings of this type, the coupling rod forms part of the air line and is therefore hollow. As a result, the. Rod to be able to withstand the heavy loads, disproportionate run heavily. In order to avoid this, according to the invention, a tube can be detached from the underside of the coupling rod attached, its downwardly bent, conical ends to accommodate the accordingly trained air hose ends serve. These are each from one to the Buffer supported double-armed lever linkage, the other end of which is hinged to a rod, which when collapsing of the coupling bolt is pressed down into its working position. Here is the Hose end passed over the associated cone of the pipe coupling and in this position held by hooks sitting at the end of the hose, which are located around the cone of the tube Lay pens.

The central buffer coupling according to the invention is shown in the drawing.

The central buffer coupling consists of one in the middle of the vehicle Front side between two common buffers ι arranged buffer 2, which is in a Hopper 4 runs out. The funnel 4 is used to accommodate a rigid, symmetrical coupling rod 3. On a vertically mounted shaft 5 on the buffer 2 sits a laterally rotatable, under spring pressure arm 6, which with its free end into the funnel opening protrudes and when inserting the rigid coupling rod 3 inevitably pivoted to the side will. In this case, a locking bolt 7 mounted above the buffer is inevitably also rotated. The locking bolt 7 is located usually in a recess of the coupling bolt 8, which thereby in its ready position is held. The coupling bolt 8 is under the action of a spring and has a toothed rack-like part, which is seated on a shaft 9 with a Gear 10 is engaged. The gear 10 is driven by a hand lever 11. On the bolt 8 a downwardly hanging rod 13 is articulated, the lower one End with one end of a double-armed

gene lever 14 is in an articulated connection. The lever 14 is on a shaft 15 on the Buffer 2 stored and carries the hose line at its other fork-shaped end 16 12. The hose 12 has an upwardly bent hose mouthpiece 17. On the underside the coupling rod 3 is releasably attached to a tube 18, the conical ends of which 18 are bent down and provided with side pins 18 ". The pins 18" work together with hooks 20 which are attached to the ends carrying the hose mouthpiece 17 16 of the lever 14 sit on pin 21 and are extended beyond this. One end lies against these extensions a lever 19 which is also mounted on the shaft 15 and at its other end is guided in the way of the rod 13. The lever 19 can extend up to the pin stop 22 move down.

The mode of operation of the coupling is as follows:

If two vehicles collide for the purpose of coupling, the one at the Counter-coupling seated symmetrical coupling rod 3 in the 'funnel 4 of the buffer 2 introduced. Here, the arm 6 is pressed outward by the coupling rod 3 until the locking bolt 7, which inevitably rotates with it, controls the coupling bolt 8 for the downward movement releases. The bolt 8 now falls into the one provided in the rigid coupling rod 3 opening and presses the rod 13 downwards. The lever 14 is thereby around the shaft 15 is rotated and the hose mouthpiece 17 is pressed against the cone 18 'of the tube 18. Simultaneously with the downward movement of the rod 13, the lever 19 rotated around the shaft 15 and adjusts itself so that he the hook 20 after the hose mouthpiece 17 is pressed against the cone 18 'of the tube 18, around the pins 18 ". As a result the hose mouthpiece 17 is held on the cone 18 '.

The uncoupling of two vehicles pushed by pivoting the lever 11, whereby the gear 10 rotates and the bolt 8 is pulled up. ZA inevitably with it if parts 13, 14, 17 are reset, and 20 in their starting position. The determination of the bolt 8 in its ready position takes place after retraction of the coupling rod 3 and pivoting the arm 6 into the funnel opening through the arm 6 connected locking bolt 7.
