SU27392A1 - Automatic coupling for railway rolling stock - Google Patents

Description

The invention relates to automatic couplings for railway rolling stock comprising a loop and hook as coupling members, which is rotated by the interaction of auxiliary buffers and moved horizontally. In the proposed coupling, the hook is provided with a shank placed in a buffer cup between the discs of the additional buffer supplied with a spring rod. One of the disks serves to hold the hook in a raised, ready-to-grip state by pressing on its shank, and the other disk- to press the hook to the adjacent carriage linked to the last loop to prevent the cars from self-splicing.

In the attached drawing of FIG. 1 shows a side view of the coupling when the cars are disconnected; FIG. 2 is a side view of the hitch, with a partial cut, when the cars are engaged; FIG. 3-top view of the coupling; FIG. 4- hook detail - side view with partial section; FIG. 5 - the same, top view; FIG. b - detail of the sleeve with a part of the hook; and FIG. 7-axial section of the sleeve with part of the hook.

T ha /, passing through the transverse channel of the car, ends, instead of the usual hook, flat ear 2

(Fig. 1 and 2), to which by means of a pin. 3, an earring 4 of the strap 5 with notches 6 and 7 is movably attached, with a double cushion 8 for the transverse shaft 9 in with the edges bent up on the sides of the notch 7. The shaft 9 passing through the pillows 72 fixed on the buffer glasses of the cars ends flush with the longitudinal wall of the carriage by the square for the swiveling key J3. In the slot 6, the shaft has a small knee L (FIGS. 4 and 5) with a square neck, onto which, by means of a sleeve 17c, a hook 7 attached with a shank / 5 is fitted with a square hole; The sleeve J7 is provided with a spike 18, which slides in the half-ring recess 19 of the hook body.

When turning the key 13 from the right to the left, the square knee // of the shaft 9 yields a semicircle with a radius equal to the eccentricity of the knee 11, and the hook 14 moves to the position indicated in FIG. 4 dotted line.

Below plate 5, a supplemental buffer consisting of buffer bowl 16 with a slot 21 in the upper part for the shank / 5 and buffer rod 22 with disks 23 fixedly mounted on it is strengthened, with the last spring abutting against the end spring, pushing forward stock 22 and themes

Hold the hook 14 in the raised state (Fig. 1).

When, at the approach of one car to another, the medium buffer plates collide, the buffer rod 22 enters the glass J6 and the disk 23 mounted on it captures a finger / 5 hook 14, which goes into slot 7 of the bar 5 of the neighboring car; in the same way, the hook of the next carriage will fall into irorez 7 of the first car. In view of the fact that the hook 14 is given | in the section conic (Fig. 4), and the hook-shaped hook has a shape like that and that on the square neck of the knee // the sleeve of the hook 17 is mounted with a certain gap (fig, 5) always tilting in any direction, when falling, falls on the grooved bar 5 and from there slides into slot 7. When the hooks of 14 adjacent cars take a horizontal position (Fig. 2), for final tightening, the coupler uses a key 13 to turn the shaft 9 with a knee / A at 180 °, with that the square opening of the sleeve 77 will take the position shown e dotted line (Fig. 4); then, hook 14 will catch with its end the bar 5 and it will not be able to disengage from the bar even if the cars, going downhill, will be pressed onto the buffers, since the middle buffer discs 23 will always press the shank 15.

To uncouple the cars, the coupler turns the key 13 in the opposite direction by a half turn, at what liiinn 18 will reach the end of the semi-circular recess 19, then the end of the hook 14 will be free in njpopez 7; upon further rotation of the key 13 to an incomplete quarter-turn, the square neck of the knee // of the shaft 9 will raise the hook 14 (Fig. 1) and the rail will thus be disengaged.

The subject matter of the invention.

Claims (3)

1. Automatic coupling for railway rolling stock, comprising a loop and hook as coupling members, rotated by the interaction of auxiliary buffers and movable horizontal, characterized in that the hook 14 is provided with a shank 15 (FIG. 2) placed in a buffer cup between the disks 23 to 23 spring-loaded buffer stocks, in order to keep the hook in a raised position ready for adhesion by acting on the shank of one of the disks and press the other disk while the buffers are squeezed, hook to the adjacent locking loop th car to prevent samorastsepleni carriages. 2. The form of the hitch according to claim 1, characterized in that to move the hook in the direction from the car when coupling and uncoupling, the hook is freely mounted by means of sleeve 17 (Fig. 4, 6) on the knee of the transverse shaft 9, swiveled by hand, ( Fig. 5). 3. The form of the coupling according to claim 1, characterized in that, in order to be able to rotate the hook up when disengaging, the sleeve is provided with spikes 18 (Fig. 4, 6) sliding in the semi-ring grooves of the hook body.
