SU77201A1 - Automatic Coupling for Railway Carts - Google Patents

Description

The invention aims to use weights to drive hooks or locking devices in automatic train couplings.

The essence of the invention is that the load placed in the automatic coupling mechanism and able to move only in the vertical direction (up and down) is connected by a screw connection with a pivot pin, which is rigidly attached to the hitch hooks (the first option), or with lever lock pr, iso1.sob. Lenin (second option). Threads screw thread on the shank of the pivot Have a corner of approach more than the angle of friction (gel-picking cut). Therefore, when the load is moved up the sludge and down, the mKBQpeHb and the hook or lever of the lock device, rigidly connected with it, turn in a horizontal plane.

This produces coupling and uncoupling of coupling devices.

FIG. 1 shows a vertical section of a coupling with turning hooks and hooks in a horizontal plane; in fig. 2-type of hitch-from above; in fig. 3-vertical

a section of the head of a two-hitch automatic coupler with a device according to the invention; in fig. 4 - top view of the head.

The king pin / is equipped with a helicon shank 2 with helicoidal cutting (Fig. I and 2). A nut 5 is screwed onto the shank, rigidly connected with the load 4, which can move up and down along the guides 5.

The load 4, coupled with the helical shank pin, by means of the nut 3 holds the hook 6 in the most closed position. When turning the pivot / into the disconnecting direction, the load 4 by the hook 6 or the handle 7 rises up. However, when the external influence on it is stopped, it returns gravitationally back down to its original position and turns the hook.

FIG. Figures 3 and 4 show the second version of the automatic coupling, where the parts noted above, adopted in this automatic coupling, are denoted by the same numbers with letters. Their action is the same as in the first version; the only difference is in constructive performance.

Here, the Prus 4a snaps the lever and the lever 8 with it, pulling out the Kamen-9 locking device.

The load 4a is made of two parts interconnected by screws 10, which are simultaneously both guide rods for the load.

- The hitch head 11 is of the c-standard asTOfCMenKH CA-3 type with an advanced body to accommodate the load in it.

The subject of the invention is an automatical coupling for railway carriages, comprising, in a horizontal plane, elements that ensure the closure of the cordon and rigidly fastened on the vertical pivots, which are rotatable around their axles, mounted in the body of the couplings, distinguishing so that the pivots are equipped with a fork, with screw thread, carrying nuts, with a load.
