Description

The invention relates to coupling devices for a train, made in the form of identical spirals with ball bearings, attached to the buffer bars and carriages. When coupling the helix of coupled cars, they enter one another and are kept in this position with the help of dogs, closing the ratchets fixed on the heels of the spirals. In the proposed device, the centering of the helix is performed with the help of an additional ball placed in the shank and loaded with a spring, resting in the corresponding recess (concave nest) of the lining, which is fixed on the buffer bar.

In FIG. 1 shows a longitudinal axial section of the device; FIG. 2 is a front view with a partial section; FIG. 3 - support detail; FIG. 4-4 - view in two projections of the end of the helix; FIG. 5 - 8 - transverse cuts of various forms of making spirals.

In the device proposed, the part directly adhering to the same part of the adjacent carriage is a helix / with pointed ends (Fig. 4-4), having in cross section one of the shapes shown in Figs. 5-8.

On the thickened head of the ball support of the helix, a ratchet shchestren / a is put on the teeth, with the dog 5 resting on the hinge bolt 6 resting its teeth. This bolt together with the bolts 16 connects the device body 2 attached to the buffer bar with the lid 3 having a wide a circular opening allowing lateral and vertical movement of the helix. Inside the head of the shank of the helix there is a sleeve 11 limited in its movements by the stop 13 with a retaining spring 10 which presses the insert 9 and through it the ball 8, which tends to occupy a central position in the recess of the washer 7. A ball bearing 12 is mounted on the yoke // in the shank of the helix, facilitating easier rotation of the helix at the moment of coupling. For convenience of centering the ring, the ring 14 is fitted with a spring / 5 threaded into its ramp, the tension of which is adjusted by the nut 17. Instead of the spring 15, it is possible to center the shank 8 of the shank in the recess of the lock 7 to give this recess a hyperbolic shape (Fig. 3). The action of the device is as follows. When the helix engages

These cars between themselves enter each other, filling in the slots between the branches of the spirals all the way into the base of the slots. In this case, both spirals or one of them rotate around its axis at a certain angle, respectively, the length and pitch of the spiral.

At the same time, dogs 5 of both cars rest against the teeth of the ratchet gears / a, an obstacle to the separation of the connected spirals. The ball 8, pressed by the spring JO to the recess of the washer 7 (lining socket), straits to keep the helix fs permanently in a normal horizontal position and 5 and 1 helixes are unscrewed from one of the cars when they diverge.

The subject matter of the invention.
