The invention relates to a transport machine building.

Known articulated vehicle containing two independent semi-frames, interconnected by means of a horizontal longitudinal hinge can move semiframes relative to each other. Inside hinge is the propeller shaft.

The disadvantage of this solution is that when driving on the tx2">

In addition, the off-road mode of this design characteristic of increased vibration and noise.

The problem solved by the invention, creating a vehicle with improved running characteristics for operation in two modes: off-road and on public roads with the safe movement of the latter with an average speed corresponding to the speed of the General traffic flow.

This object is achieved due to the fact that in the known articulated vehicle, mainly with all-wheel drive, containing two independent semi-frames, interconnected by horizontal longitudinal hinge through which the drive shaft of the rear axle, according to the invention between frames set adjustable hydraulic cylinders.

Hydraulic cylinders upper ends attached to the first frame, and the lower second.

The lower mounting point of the hydraulic cylinders are posted towards the top.

The hydraulic cylinders are connected by pipes, one of which has a stop-cock.

The control valve is connected with the switching lever is eivana turn semiframes, consisting of adjustable hydraulic cylinders, allows you to select each mode of motion of the corresponding characteristic campfire of oscillations between frames, which improves driving performance of the vehicle when driving on public roads and increases the life of semiframes. With the help of adjustable hydraulic cylinders is achieved, such an amount of angular displacement of semiframes, which is sufficient to overlap one stroke the ball diameter, which eliminates pitting of bearing, connecting semi-frames.

The presence of two pipes between the cylinders allows the use of cylinders with a low degree of sealing of the piston.

Synchronizing crane control cylinders and gear lever transfer case allows you to simplify the management control system and hydraulic cylinders.

In Fig. 1 shows a view of the vehicle in plan; Fig. 2 is a side view, and Fig. 3 diagram of the adjustable hydraulic cylinders.

Articulated vehicle 1 with the all-wheel drive, contains two independent semi-frames a and B. semi-frames a and B are connected with VOZMOZhNOSTI the drive shaft 4. Between pournami a and B established a mechanism for tracking the rotation of semiframes, including hydraulic cylinders 5 and 6. The hydraulic cylinders 5 and 6, the upper end 7 attached to the end A, and the bottom 8 of the section B. the Lower attachment point 8 posted towards the top 7. The hydraulic cylinders 5 and 6 are connected by pipes 9 and 10. The pipe 9 has a shut-off valve 11. The control valve 11 is synchronized with the handle 12 of the control transfer box.

The vehicle operates as follows.

When driving off-road included reduction gearing of the transfer case and simultaneously open the valve 11 in the pipe 9. Thus the cylinders 5 and 6 communicate with each other and with the course of the cylinder piston 5 up liquid pipeline flows into the cylinder 6, the piston stroke of the cylinder 6 down will be equal to the go up of the cylinder piston 5.

When driving on public roads included increase transmission transfer case and the valve 11 is closed. Communication between the cylinders through the pipe 10. Due to the flow of fluid through the piston in the lower chamber and the cylinders operate in its normal mode. So oraclebase, transmitted from one semi-frames to the other, and also prevents pitting in the bearing.
