Description

This invention relates to a vehicle, namely a coupling device for vehicles.

The purpose of the invention is to increase reliability and durability.

Fig, 1 shows the coupling device in the disengaged position; in fig. 2 - the same, top view; in fig. 3 - the same, in working position; in fig. 4 - the same, top view; in fig. 5 is a view A of FIG. one; in fig. 6 is a section BB in FIG. 3

The coupling device comprises a catcher 1 with a tapered bore 2 mounted on one of the coupled links (s), mounted on the other coupled link rod 3, the end of which is made in the form of a truncated cone, the groove 4 of which has a larger diameter.

At the input of the catcher 1, the ring 5 is mounted with the ring groove 6. The ring 5 is prevented from axial movement by means of the bolts 7 that the washer 8 is fixed to the catcher 1. The locking cables 9 are fixed by one ends on the ring 5, and by others on the catcher 1.

The drive of the coupling mechanism consists of a cable 10 laid on the outer cylindrical surface in its groove 6, which is fixed at one point 11 blocks 12 and 13 with a horizontal axis of rotation, blocks 14 and 1 with a vertical axis of rotation, which

serve to guide the cable 10 and the chain 16 attached to the ends of the cable 10 to the envelope of the sprocket 17 of the torque limit clutch 18 and the electric motor 19.

five

The device works as follows.

In the disengaged position of the hitch, the ring 5 is positioned so that the flexible cables 9 are in an unloaded state and hang loosely to form a loop. The point 11 of attachment of the cable 10 to the ring 5 is located on the right (Fig. 5), the right end of the cable 10 (its connection to the chain 16) is located on the sprocket 17, and the left end of the cable 10 is on the block 15 (Fig. 2). the coupling of the taper of the boom 3 enters the conical bore 2. The electric motor 19 rotates the sprocket 17 through the coupling 18 of the hub shaft moment; which moves the target -16 and the left end of the cable 10 is pulled to the sprocket 17, and the right to block 14, as a result ring 5. At the same time, flexible cables 9, tensioning and falling into the groove 4, tightly press the cone of the rod 3 2 catches the conical hole 1, providing engagement engages proxy units,

The uncoupling of the links occurs when the direction of rotation of the electric motor 19 is reversed.

Claims (2)

1. COUPLING DEVICE comprising a catcher fixed to one of the links to be connected with a conical hole, a rod mounted on another link to the link, the end of which is made in the form of a truncated cone corresponding to the shape of the catcher, and a coupling mechanism, characterized in that, in order to increase reliability and longevity, the coupling mechanism consists of a ring mounted at the inlet of the catcher, mounted with the possibility of rotation by means of a drive, fixing cables, some ends of which are fixed to the ring, and others to catch barely, and these cables are installed with the possibility of interaction when engaging with a groove, which is made at a larger diameter of the truncated cone of the specified rod. 2. The device according to claim 1, characterized in that the coupling mechanism consists of a cable laid on the outer surface of the ring and fixed at one point in the chain attached by the ends to the specified cable, and a drive sprocket of an electric motor with a coupling of the longitudinal moment and supporting currents. b FIG. / ¹ 122
