Description

The proposed automatic coupling device refers to such devices of this purpose, in which coupling bodies, made in the form of a hook and loop, are mounted directly on the buffer cup and interlock with the corresponding bodies of the adjacent carriage when the buffers of the linked cars interact. In the proposed device, both coupling bodies — a loop and a hook — are hingedly connected with earrings to the plates of the buffers, and during coupling the hooks are locked with a spring stopper.

In FIG. 1 is a front view of the device of one car; FIG. 2 is a top view of the instruments of the two cars until coupling; fig; 3 is a top view of coupled instruments; FIG. 4 - side view of them; FIG. - view of one part of the release lever.

The actual coupling bodies of the device, hook 3 and loop 5, are pivotally mounted on rollers 12 and 13, respectively, mounted in the hollow box 1 of the device, connected by a shank 14 to the traction rod of the car and mounted on the buffer bar along the same axis as the buffer. The latter, together with its rod, spring 15 and with the oval cut off (Fig. 1) plate 2, is placed, with the possibility of axial movement, inside box 1. Buffer plates have on the inside

two ears 4 each (figs. 2 and 3) with axles inserted in them, on which an earring b is put on in one ear, connected with a hook 3, and an earring 9 in the other ear, connected with crank 10 of the roller 13, on which tightly seated loop 5.

In the normal position before coupling the cars, when the buffer plates are pulled out of the boxes 1 with their springs 15, the loops 5 and the hooks 3 occupy the position shown in FIG. 2- When coupling the cars, the buffer, touching each other, rotate, by means of the articulated joints 9-10 and b, the loops 5 and the hooks 3, so that the first engage with the second, taking the position shown in FIG. 3, in which, in this position, there is a spring stopper 8, which rests on the side of the hook 3 from below, in the state before adhesion (Figs 1 and 2) and rises up along the passage above it, which turns when the cars hook up; thus, the stopper 8 secures the hook to the loop.

To uncouple the cars, this stopper is pushed manually down by means of the crank lever 7 (Fig. 5), located in a convenient place on the side of the car, and then, under the action of the buffer spring 15 on the plate 2, the released hook 3 and loop 5 are consumed mc

In order to prevent spontaneous accidental insertion of the stopper 8 in the disengaged car, the lever 7 is locked by the stop P (Fig. 5).

The subject matter of the invention.

automatic coupling device in which the coupling bodies, made 8 hook and loop form, are installed

directly on the buffer cup and interlock with the respective bodies of the adjacent car when interacting with the buffers of the coupled cars, characterized in that both coupling bodies are connected to the buffer plates with hinges by means of hinges and are locked by the spring stopper 8, which holds the hook 3 from rotation.
