The present invention relates to self-propelled unit with articulated chassis.

The prior art self-propelled units, chassis, which consists of at least two parts are pivotally rotated relative to each other around an essentially vertical axis, and each of these parts installed at least on one axis, at least one of these axes is the guide, and at least one of these axes is the leading; in addition, this unit includes means for selective rotation of these parts of the chassis relative to each other.

In this unit articulated chassis there is the possibility of reducing the turning radius compared to the same unit with monoblock chassis that gives special advantages for a considerable length of the unit.

In particular, this applies to some agricultural units such as sugar beet, the length of which often reaches twelve feet.

Another problem that must be addressed in such units is articulated chassis is to obtain maximum stability on the ground. Therefore, measures were taken to ensure free rotation of one axis relative to another around essentially the longitudinal axis, i.e. an axis parallel to the direction of movement of agrega the A.

For this purpose it was necessary to develop a connection type ball joint between the two parts of the chassis, however, this task proved to be too difficult in terms of manufacturing and maintenance of such system.

Thus, the aim of the invention is a simple technical solution of the stated problem to provide the necessary stability for the soil unit articulated chassis.

This goal is achieved thanks to the self-propelled unit having a chassis, comprising at least two parts are pivotally rotated relative to each other around an essentially vertical axis, and each of these parts installed at least on one axis, where at least one of these axes is the guide, and at least one of these axes is leading, with the specified machine includes means for selective rotation of these parts of the chassis relative to each other and is characterized by the fact that one of these axes is arranged to swing on the relevant portion of the chassis.

In the context of the present invention, the expression "swing" means that the corresponding axle can rotate freely around essentially the longitudinal axis relative to the corresponding part of the chassis, resulting in permanent contact of all wheels of the unit with the soil, and trace the educational, and extremely high stability of the unit.

Thanks to the above characteristics is achieved by spatial separation of the hinged connection with each other around two axes, essentially, a longitudinal axis and swivel with each other two parts of the chassis around an essentially vertical axis. The result is two independent swivel, each of which can easily be performed with the use of traditional tools type axial connecting rod. Due to this it is possible to eliminate the complexity in design and difficulty of maintenance known from the prior art systems with a ball joint.

According to other optional features of this unit:

- specified rotary means include at least one power cylinder, is placed between these two parts of the set can be rotated relative to each other - the use of such a power cylinder allows you to perform the rotary tool without much difficulty;

- this Central part of the chassis is made essentially in the form of an open frame;

- a second axis, i.e. one that is not swinging, contains a device for position correction.

Other characteristics and advantages of the invention are readily available from the following disclosure of the invention with consideration of the attached drawings, where

- figure 1 schematically presents a side view beet Assembly according to the claimed invention;

- figure 2 schematically presents a top view of this Assembly.

In these drawings the usual direction of movement of the beet unit shown by the arrow F.

This machine has a chassis 1, which consists of the front part 3, the Central part 5 and the rear part 7.

The front part 3 of the chassis is installed on the front axle 9 and is rotated around the hinge, essentially the longitudinal axis A1 relative to the Central part 5.

The word "longitudinal" should be understood as "essentially parallel to the direction of movement of the unit.

On the front part 3 of the unit installed motores 11, which console is from the front end of the front part of the chassis.

The tank 12 of the unit is installed, preferably on the front part 3 of the chassis.

On the Central part 5 of the chassis is installed cabin 13, which is the operator for controlling the operation of the unit.

Under the Central part 5 of the chassis is suspended from the means for extracting and transporting the fruit of the beets.

In the example presented here extracts form the pair of rails 15 and rotating disks 17 and the conveyor means are rotatable grating 19, and all these bodies hanging from the bottom of the frame 21, which in turn is suspended under the Central part 5 of the chassis.

It is obvious that the invention is in no way limited to the above extraction and transport means, extracting means can consist, for example, a simple stationary or vibrating plow blade and the conveyor means may take the form of moving belts or conveying rollers is well known to specialists.

It should also be noted that predpochtitelno (see 2), the Central part 5 of the unit is made in the form of an open frame, and not the Central beam, as is the case in machines known from the prior art.

In this case, the hydraulic hoses and electrical cables necessary for operation of the various organs of the Assembly can be skipped along and inside the lateral columns of the specified frame.

With this design is able to fully release the space above means 15, 17, 19, which facilitates visual control over these funds by the operator located in the cab 13.

The rear part 7 of the chassis is made pivotally rotatable about the Central part 5 around the essentially vertical axis A2. Between these parts 7 and 5 placed drive means such as hydraulic power cylinder 23.

The rear part 7 of the chassis is installed on the rear axle 25, the heat motor 27 mounted on this rear part, provides actuation of all functional units.

In particular, this heat engine allows to move one or both axes 9, 25, bringing the rotation of the rotary grating 19 and the operation of the hydraulic unit for influencing the power cylinder 23.

Transferring motion from a heat engine 27 to the front 3 and the Central 5 parts of the chassis by using the special is a high cardan or fluid coupling 29.

On the rear part 7 of the chassis is also fixed storage hopper 31 which is connected with the ascending conveyor belt 33 (such conveyors is usually called "lifts").

The mode of operation and advantages of the unit according to the invention become clear directly from the slide above.

When moving the unit beet field motores 11 begins to remove beet growing on them tops.

Due to the fact that the front part 3 of the chassis freely pivotally rotated around the longitudinal axis A1 relative to the Central part 5, the front axle 9 can be repeated change of the slope of the ground, and as a result it is possible to maintain all four wheels of the unit in constant contact with the soil, thus obtaining an extremely high stability.

Because motores 11 is connected with the front part 3 of the chassis, it is possible to constantly maintain the position of bataraza parallel to the soil, which allows to achieve very high efficiency of removal of the tops.

As is well known in the art, a pair of rails 15 and the disks 17 provide effective extraction of the fruit of the beets from the soil and transports it to the rotary grating 19 to purify them from the earth and transported to a storage hopper 31, either directly to the outside.

If necessary, lift 33 provides izvlekaemogo beet from the hopper drive 31 and transports it to the outside, for example, in the trailer goes behind the tractor.

When the operator located in the cab 13, you will need to perform a maneuver unit, for example, the u-turn at the end of the field, it affects the (those) of the two axes 9, 25, which (who) is (are) guide (guide).

In order to reduce the turning radius, it can also affect the power cylinder 23 to rotate the rear part 7 of the chassis relative to the Central part 5 around the essentially vertical axis A2.

From the foregoing it is clear that the means providing the hinged rotation of the front part 3 of the chassis relative to the Central part 5 around essentially the longitudinal axis A1, on the one hand, and means providing a hinged rear part 7 of the chassis relative to the Central part 5 around the essentially vertical axis A2, on the one hand, are located in different places of the declared unit and work completely independently from each other.

Each of these tools can be the ordinary traditionally used swivel axial rod exceptionally simple design.

Due to this it is possible to create a car that is both small radii of curvature, and exceptionally high resistance on the ground, and no need to use any SL is the author of hinge joints. This creates an opportunity to reduce cost and increase reliability in comparison with the known prior art machines with ball joints.

It should be noted that, due to the fact that the fuel tank 12 is located on the front part 3 of the chassis, it is possible to improve the adhesion of the front wheels of the unit with the ground, which promotes a more efficient penetration into the soil means 15 and 17.

It should be obvious that the invention is in no way limited to those disclosed above and shown in the drawings, the exemplary embodiment which is given solely for illustrative purposes.

For example, it is possible to provide such a construction in which the rear axle 25 will contain a device for correcting position, i.e., any device with a hydraulic actuator, which provides the opportunity to actively change the tilt of this axis relative to the rear part 7 of the chassis. This device will allow you to compensate for the slope of the ground and, therefore,

- better distribute the weight of the hopper drive 31 to the rear wheels, and

- to maintain the horizontal position of the Central part 5 of the chassis and the cab 13, thereby increasing the comfort for the operator.
