The invention relates to a transport machine building.

Known vehicle containing two independent semi-frames, interconnected through a hinge so that they can move relative to each other, and the intermediate frame, provided with two rollers for each semi-frames.

The disadvantage of this solution is that articulated semi-frames can be moved relative to each other only under off-road. However, when driving on public roads, this vehicle can only be driven at a low speed, without creating interference with the safe movement.

Known for an articulated vehicle having all-wheel drive, containing two independent semi-frames, pivotally interconnected through a hinge with a horizontal axis connecting the semi-frames, passes the propeller shaft.

The disadvantage of this solution is that the bearing that connects the semi-frames, perceives load and semiframes and from the propeller shaft, so it must be made of high strength material with a large wall thickness. As strong must be performed and the elements connecting the bearing with pournami. In addition, the off-road mode of this design, providing a high permeability characteristic of increased vibration and noise.

The problem solved by the invention, to relieve the bearing installed between pournami, to increase the resource of his work, to expand the area of its operation while maintaining the lowest possible size.

This object is achieved due to the fact that in the known articulated vehicle, mainly relative movement around a horizontal axis through the bearing, through which passes a drive shaft, according to the invention bearing, connecting semi-frames, has an inner diameter allowing free movement therein of the propeller shaft. At the second end on the same geometric axis of the main hinge is an additional horizontal hinge.

The movable element of the additional hinge is rigidly connected with one end of at least one beam, the other end of which is rigidly with the possibility of separation is connected with the first end via a connecting element mounted on the first end.

The presence of between pournami bearing with an inner diameter allowing free stroke of the drive shaft and reduces the load perceived by the bearing, which increases the service life of the bearing, allows with minimal cost to make the conversion of any wheel or have the drive to one axle of the vehicle in the universal dual-mode vehicle. Through this hole bearing, you can skip the wiring, brake hoses, etc., because this region of the articulated vehicle is the least subject to fluctuations, i.e. the minimum is veroyatnogo hinge allows you to offload the main hinge for any type of dynamic alternating loads, that makes it possible to keep the minimum possible dimensions of the hinge and to improve cross-country vehicle. In addition, the presence of connectors associated with the movable element allows you to track the movement of one semi-frames relative to the second and thus neutralize the resulting alternating loads.

In Fig. 1 shows a view of the vehicle in plan; Fig. 2 is a side view, and Fig. 3 scheme razrusheniya bearing.

Articulated vehicle 1 with all-wheel drive contains two independent semi-frames a and B, connected with the possibility of relative movement. Between pournami is the main hinge 2 having an inner diameter of 3 sufficient to free passage through it of the propeller shaft 4. In section B coaxially with the bearing 2 on the bracket 5 has a movable element 6 (as element 6 can be used, for example, a shaft mounted in the bearings, or ball bearing, ball or plug), rotating around the axis 7. To item 6 narashima attached bars 8 and 9. The second ends 10 bars Rethimno fixed on the connecting elements 11 semi-frames A. the Ends 10 of bars spaced apart from the longitudinal axis of automobilului a and B can be moved around a horizontal longitudinal axis of the one relative to the other at an angle of up to 23about. The possibility of relative displacement provides a hinge 2 connecting the semi-frames And thrust 8 and 9, the rotating element 6 and the tracking movement of one semi-frames relative to the other, unload the hinge 2 and increase the area of its operation (see Fig. 3). Resulting longitudinal force load between pournami a and B are regarded primarily connectors 8 and 9, since they are rigidly connected (without backlash), partially extinguished due to their own elasticity, and then passed on to the hinge 2.

When driving on public roads structure of power works in the same way as when driving off-road, taking the maximum loads and unloading the hinge 2.
