The invention relates to trackless vehicles, in particular to the construction of two machines with articulated frame.

Known coupling device containing a hinge with a vertical axis and a hinge with a horizontal axis, a shaft located in the bearing housing of the rear link and pivotally connected with the front link, and a toothed locking mechanism of the hinge with a horizontal axis [1].

The disadvantage of this device is the inability to lock the hinge with a horizontal axis in an arbitrary position of the parts, for example, when working on slopes (lock occurs only at considerable angles of folding links). This construction, moreover, does not protect the mechanism against mechanical and atmospheric influences.

The technical result achieved by the claimed solution is to increase the reliability of the locking mechanism and the possibility of using it in an arbitrary position of the parts of the machine to increase security.

This result is achieved by coupling two vehicles containing the hinge with a vertical axis and a hinge with a horizontal axis, the shaft, the location is Arnie with a horizontal axis, when the locking mechanism is placed inside the semi-frames and are made with spring-loaded blocks with locking teeth and the support surfaces mounted in the slots of the housing of the rear link, rigidly mounted thereon, and a drum having an internal surface area for interaction with the supporting surfaces of the spring pads, and the drum set can be rotated on the bearings, mounted in the rear of the link, around a horizontal axis under the action of the actuator, the shaft opposite the spring-loaded pads provided with locking teeth arranged in an arc, the corresponding maximum permissible angle of rotation of the links about the horizontal axis with the possibility of engagement with locking teeth spring pads when they move in the radial direction when subjected to the supporting surface of the spring-loaded pads pads drum.

The claimed technical solution is illustrated by drawings, where:

Fig. 1 coupling two vehicles,

Fig. 2 - section a-a in Fig. 1.

The coupling device includes a shaft 1 mounted in the bearings 2 of the hinge with a horizontal axis of the rear element 3 and holodoc 6, placed in the slots of the housing of the rear link and having locking teeth and the supporting surface of the drum 7 sites 8 mounted on the supports 9 and associated with the actuator 10.

The device operates as follows. When driving two vehicles on rough terrain is turning the front 5 and rear 3 links relative to each other around a horizontal axis. The maximum angle of rotation determined from the conditions of safety, up to 25 - 30oin each direction from the horizontal position. In order to increase lateral stability, especially when working on slopes, there is a need for a locking hinge with a horizontal axis in any position of the links. Under the influence driver control drive 10 rotates the drum 7 on the supports 9 around the horizontal axis. When this pad 8 on the inner surface of the drum effect on the surface of the spring pads. The latest move in a radial direction and includes its locking teeth engages with the locking teeth of the shaft 1, arranged in an arc corresponding to the maximum permissible angle of rotation of the links 3 and 5 around the position.

The tests confirmed the efficiency of the device as the reliability of the locking mechanism. At present JSC "AMZ" preparation of serial production of two vehicles described hitch.
