The invention relates to vehicles, particularly the articulation of two all-terrain vehicles.

Known articulated wheeled vehicle used in wetlands without roads areas [Vaanile, Utevoditel. Tractor with a "breaking" frame. Design and calculation of agricultural tractors. M: "engineering", 1976, str, 384].

Known subcompact vehicle containing the articulated section [EN 582 U, 1993].

Known vehicle "wanderer", containing the articulated section [http://stran06.narod.ru], selected as a prototype.

The disadvantage as analogues, and the prototype is that Rovers have a pretty metal hinge, solenaye section and reinforced where it mounts to provide the necessary strength and dimensions solanales hinge are of considerable size, which in turn reduces buoyancy and useful volume sections, and not very high-tech sealing sections.

The purpose of this technical solution is to increase the patency of the vehicle, mainly of the vehicle on rough terrain and over water obstacles.

The technical result is to reduce the weight of the vehicle without loss of strength and deterioration of controllability on land and water, and increasing water the mix and more reliable sealing of the sections in the passage of the shaft.

The problem is solved and the technical result is achieved by the fact that, as is known, the proposed vehicle-terrain contains two sections - the driving and driven, interconnected.

What's new is that the sections are connected using two fixing points: bottom, representing the universal joint, and the upper, which is located at some distance from the bottom on the vertical axis, representing the steering device.

While the hinge shafts passed through the casing sections, in which are mounted bearings.

Preferably, the universal joint has been made in the form of a cross.

In addition, the steering device contains a U-shaped sector mounted on the drive section, inside of which is mounted rollers mounted on steering equal armed lever, which is in turn attached through the axis to the leading section.

In the present invention, in the vehicle-terrain vehicles (two-Rover) serves to articulate sections using two attachment points - the bottom and top, located at a distance h along the vertical axis from the bottom.

Traditionally, all articulated vehicles used only one lower attachment point - swivel, located in the area and passing through the propeller shaft. As the lower attachment point of the sections in the present invention it is proposed to use directly the universal joint, with the universal joint may be made in the form of crosses or other structures that can withstand radial and axial loads. To this end, the housing sections (as on the guest and on the host) are angular contact bearings, in which are mounted the shafts of the hinge. With this design, the shaft not only transmits the rotation from the driving unit to the driven, as is also the lower mounting point of the sections. At some distance from the lowest point on the vertical axis of the mount is mounted an extra swivel in the form of a steering device, connecting the casing sections, the upper attachment point that allows you to post attachment point height, thereby greatly reducing the stress on the attachment point.

Both attachment points (lower and upper) are the axis of rotation of the sections as the horizontal (longitudinal)and vertical axis that allows you to make the turn due to the deviation of one section relative to another along the vertical axis at an angle up to 25, the horizontal axis allows parallel one section relative to another at an angle up to 25.

Because the proposed construction of two attachment points, cosily, acting on these points, reduced inversely proportional to the distance h (Fig 1).

Therefore, the partition can be made frame - lighter, not having semiframes and not so reinforced in places of fastening.

When using the appropriate materials weight solanales device will be reduced, maintenance-free period will increase, because the dynamic load on the attachment decline.

The invention is illustrated graphics.

Figure 1 shows a side view of the proposed vehicle with top and bottom mounting point.

Figure 2 shows a top view of the proposed vehicle.

Figure 3 shows a section a-a and b-At the top attachment point.

Figure 4 shows the side view of the lower mounting point.

Figure 5 shows a top view at the turn of the proposed vehicle.

Figure 6 shows a front view when the distortion of the sections along the longitudinal axis.

The proposed vehicle contains two sections: the front (leading) 1 and the rear (driven) 2, the articulation of which is executed in the form of two attachment points: the lower 3 and upper 4, wherein the lower fastening point 3 (universal joint) made in the form of crosses 5 connecting the shafts 6 and 7, the sealing of which is carried by the seal 8 (figure 4), and the upper fastening point contains a U-shaped sector 9,fixed to the body of the rear section 2, inside of which are mounted rollers 10 mounted on steering equal armed lever 11, which in turn through the axis 12 attached to the front of section 1. Tie rods 13 and 13 connected to the lever 11.

The housing sections are made of steel hermetically sealed, welded frames from a shaped tube of rectangular cross-section, to which is welded thin steel sheets. The shafts 6 and 7 are fixed to the casing sections with double-row angular contact ball bearing type Dac 43840039. The distance h is the distance between the center of the spider and place of the fixing upper roller on the axis 12. The distance is determined by the magnitude of the housing sections. U-shaped sector has a sufficient length to provide a distortion section along the longitudinal axis at an angle of 25 in both directions. The ends of the sector brewed and have rubber bumpers 14 limiting the extreme positions of the rollers 10. The rollers 10 are made of sth HRC 50...55 and rotate to a closed radial bearings. The axis 12 in place of the fixing upper roller is made eccentric to choose the gap, i.e. the axis 12 is rotated up until the extreme rollers will not touch the opposite inner side of the sector, and then rigidly fixed.

The device operates as follows. When turning the vehicle steering rods 13 act on the lever 11, which is rotated on an axis 12, thereby is flipping the s partition 1 on partition 2 on the vertical axis (figure 5). When driving on rough terrain (6) section warp along the longitudinal axis, the axis of rotation is a shaft that receives the rotation.
