Description

The invention is an improvement to a lock holder in a double-tooth lock rail coupling.

The lock holder and the automatic coupling lock are simultaneously under the action of a spring located in the cavity of the large tooth of the coupling body. The lock holder is provided with a process entering the throat of the coupler from the side of the horn.

With such a position of the lock holder, the reliability of the closing automatic coupling mechanism depends less on tolerances, wear and clearances along the engagement circuit, because in the case of a clutch, the lock will always be ahead of the movement of the extension, which prevents the automatic coupling mechanism from breaking at the moment of adhesion.

FIG. 1 shows a partial cut coupler ready for protection; in fig. 2-section automatic coupling ABCD; in fig. 3-clutch with partial cut in engagement position.

Lock holder / pivoted in the horizontal plane about axis 2 k is provided with a process 3 entering the junction box of the automatic coupling

From the side of the big horn 4, the arm 5, interacting with the lever 6 to hold the lock 7 in the uncoupled position before opening the couplings and the appendix S, which interacts with the locking pin 9, which locks the automatic clutch lock 7 in the concatenated joint.

In the free (unlinked) coupler (fig. I) of the heck 9, under the action of the appendix 8, it is in its upper position and allows the lock 7 to freely move into the hitch pocket, since the stops 10 and the lock // do not interact with the locking pin 9, what makes the coupler ready for coupling.

In the coupled automatic coupling (Fig. 3), the appendix 8 of the lock holder 1 is located in front of the locking cheek 9, which causes the latter, falling down, to become between the blinders 10 // of the lock 7 and the body of the automatic coupling, which prevents the longitudinal movement of the lock 7.

The clutch lock 7 and the free auto price always tend to protrude into the throat of the coupler under the action of the spring 12, which acts on the lock 7 through lever 6 (lift).

To disengage the automatic coupling, it is enough to lift the lever 7 with the lock 7 to its rearmost position. When moving the lever 6, the latter first raises the locking latch 9, thereby unlocking the lock 7, and then acts directly on the lock, withdrawing it to its extreme rear position. When the lock 7 is completely retracted to the extreme position, the lever 6 protrudes from the inclined surface over the protrusion on the shoulder of the locking holder and is held in this position until the couplings are divorced, i.e. the appendix 3 of the locking holder 1 reaches the automatic coupling throat .

In order to reduce the influence of inertial forces, as well as friction forces acting on the locking pin 9 at the coupled coupler, spring 12 has a process 13 that rotates together with the lock holder / and is located in the coupled couplings above the stop 14 of the locking pin 15, thereby preventing lifting locking heck 3 up.

By applying the elastic process 13 of the spring 12, the coupling release is facilitated.

The above arrangement of the coupler mechanism allows a considerable reduction in the overall dimensions and thus the weight of the coupler.
