SU51339A1 - Automatic coupling for carts - Google Patents

Description

Uzho is known for a whole range of automatic carts, in which the coupling bodies are made in the form of an arcuate eccentrically mounted disk, which engages with a non-glue (hook) of the opposing column. The disadvantage of this scene is an open (gap) between the nettle and the bridge, i.e., the scene does not have the necessary rigidity, as a result of which the hinge bodies themselves develop, hence their rapid wear. In order to avoid this drawback, a sketch is proposed, described below, in which the loop, coupled with Dna, is set up by the same disk, by proper (THEN turn.

On Chertelhe FNG. 1 depicts a scene and open position; fng 2 - in an intermediate position; FIG. 3 - in the clutch iolozepy and fng. 4 - scene at the time of its release.

The scene is composed of two main parts. The first of these parts 1 is attached to a moving vehicle (tractor). Druga 2 sv.zapa with movable carriage.

Part 1 depicts a box within which a part can be moved, wasps, which are projected on the case of both carts. This latter part is composed of a disk 3, capable of being eccentrically rotated on a strong axle 4. tightly fixed in box 1.

The disk 3 has a large recess 5, which includes a part associated with the coupling device of the trailing head. In a smaller recess, 6 tongue 7, rotating on the collar 8. This tongue 1 is under the influence of the spring 9, which its iodderl tends to stretch its tension by pulling the tongue in a raised position. shown in FIG. 1 and 4. The cylindrical plunger 10 is located in the near-axis axial direction of the disk 3. This shaft has an inclined surface 11, which ends at the end of a steeper surface 12. 11-rodol; the bottom of the barrel is 13 hectares, ending with B dank-shaped with a fork 14 which connects the valve to the control, namely to the lever 15. A spring 16 falls onto the plunger in such a way that its valve is always keniv pushing the plunger inside the box 1.

Box 1 is mounted on a rolling circle 17 associated with a driving vehicle. This makes it possible to follow all the turns of the road with a valuable carriageway without disturbing the normal operation of the device. The automatic coupling device arranged in this way acts as follows. .

In the case of Leni (fig. 1), the plunger 10 is retracted by the lever 15 back to the position shown in FIG. 4. Disk 3, which is no longer held, loses raviocoea and falls in the direction of arrow 18 (Fig. 1). the notch 5 automatically facing the mouth of box 19 of box 1. Through the reverse movement of the movement of the cart or by moving the movable cart forward, part 2 is inserted into the box 1 and procs the hatch 5. With the continued approach of both carts, movement of part 2 causes the disc 3 to rotate in the direction of the arrow 20 (intermediate position shown in Fig. 2). This movement causes tak5K (lowering the tongue 7. As soon as the lower stop of the irunger 10 comes out of the joint 3 with the periphery of the disk 3, the plunger will be pushed forward by stretching the spring 16 and the disk 3 will lock (Fig. 3).

Due to the surface 11 forming the inclined plane, the plunger 10, always under the action of the spring 16, is moving forward, not leaving a gap between itself and the disc, which gap could arise from jolts caused by the movement of carts. By rotating the disc 3, it engages both carriages, and a part of the load can be transmitted to the moving carriage by lifting the front part of the trailer carriage.

All traction efforts are perceived by contacting the tips on the surface in no way can be the cause of breakdowns.

As mentioned above, depending on the towed load, the number of gearbox 1 can be increased, and

their shape is such that it allows you to put several boxes on the circle.

Thus, the adhesion is achieved by the mutual arrangement and connection of the organs shown in fig. 3

When uncoupling (Fig. 4), it is sufficient, by means of lever 15, to retract the plunger 10. When the plunger retracts, the tongue 7 automatically lifts under the action of the spring 9. When this tongue is maximally raised, it turns out to be exactly opposite to the thrust surface 12 and contact with this surface forms a delay, which does not allow the plunger 10 to return to its original position.

In order to understand the release actuation, it should be noted that the surface of the anvil 12 is inclined in such a way that it cannot prevent the repositioning of the disk 3, which is done as follows. By moving forward a moving wagon or by haulage of a movable wagon, part 2 abuts against the surface of recess 5 and causes the disk to rotate in the direction of arrow 18 until part 2 is panned against box 19 of the box 1. From this point on, plunger 10 will rest against the periphery of disk 3 13, thus the whole device will automatically be in the position shown in FIG. one.

The subject of invention.

An automatic hitch for carts using a box reinforced on a tighter side, carrying a plunger cooperating with a swivel disk serving to grip a hook, characterized in that to eliminate slack between the disk and the hook, the plunger 10 is provided with a wedge surface 11, which transforms into an abutment plane 12 that interacts with the tongue 7, and the rotation mounted on the disk 3.
