The invention relates to a vehicle, namely articulated vehicles.

The purpose of the invention is to increase maneuverability.

Figure 1 shows an articulated vehicle, a general view; Fig.2 diagram of the drawbar and intermodular drive, side view; on fig.Z - drawbar diagram, top view; Figures 4 and 5 show the first and second phases of rotation of the energy module relative to the transport module, respectively.

The hitch of an articulated vehicle, including the energy module 1 (figure 1) and the active transport module 2, consists of a connecting link 3, the bracket A of the energy module, the bracket 5 of the transport module and the drive 6 (figure 2) of the active transport module 2.

The connecting link 3 contains a pipe 7, t: one pivotally with pins 8 of a vertical hinge, connecting link 3 with a bracket 5, and plugs 9 mounted loosely on the pipe 7 and pivotally connected with pins 10 of a vertical hinge connecting the pipe 7 bracket 4. Pipe 7 contains hinges 11 and 12 (Fig. 3), located in the horizontal plane on both sides of pipe 7, connected to spring-loaded links 13 and 14 of two-sided action. The latter are equipped with stops 18-20. pre-compressed springs 21, movable washers 22 and 23, and t gami 24.

The actuator 6 is connected through a double cardan plug 25 to the drive shaft 26 of the core 27 of the energy module 1 and through a double cardan fork 28 to the drive shaft 29 of the frame 30 of the active transport module 2.

- The bracket 4 is connected to the connecting link also by the axles 31 of the horizontal hinge, and the bracket 5 is connected to the connecting link by 3 axles 15 of the horizontal hinge. Spring-loaded links 13 and 14 are connected by the respective hinge 16 and 17 with the bracket 5.

The hitch of an articulated vehicle operates as follows.

In the linear motion mode with respect to the pins 31 and 15 of the brackets 4 and 5, the energy module and the active transport module can change both the angular position to overcome uneven terrain and move at different levels.

In the horizontal plane, the displacement of the core 30 of the active transport module is limited by stabilization (by the moment of the pre-loaded springs 21

links 13 and 14 bilateral action.

In the mode of the first phase of rotation (Fig. 4), the power module 1 freely rotates relative to the trunnions 8 (Fig. 2) of the bracket 5 by an angle a (Fig. 4).

With an increase in the angle of rotation (the second phase of rotation, figure 5), turning against the hinges 16 and 17i, link 13 lengthens and link 14 shortens. The angle of rotation of the energy module with respect to the axis of movement of the active transport module is doubled.

The springs 21 of the links 13 and 14 are compressed simultaneously. The stabilizing moment is equal to the sum of the moments of the springs of the links 13

and t4 increases.

Overcoming the stabilizing moment of the springs of the links 13 and 14 is ensured by the moment of force of the energy module relative to the pins 8 of the bracket 5

and the power of pulling force of the active transport module with respect to the pins 10 of the bracket 4.
