The invention relates to the field of engineering, in particular to the structures of protonotary vehicles and can be used in many industries.

Known lift, containing a working space, freely suspended by means of two hinges at the end of the boom, the suspension point which is located above its center of gravity [1].

The disadvantage of such a suspension is the deviation of the working platform from the horizontal plane during its movement under the action of the offset of the center of gravity of the load placed on it.

The prototype of the invention is selected trolley with tiltable body, comprising a support mounted on it through axis grotonover and mechanism of equilibration of protonotes about its axis, made in the form of two shoulders of the lever mounted on the support vehicle and interacting one-shoulder with gruzomobile [2].

The disadvantage of this design is the unbalance of the work platform trolley (i.e. protonotes) from the offset of the center of gravity of the cargo located therein about the axis of its suspension, which leads to uneven wear of the vehicle.

Object of the invention is the equilibrium of protonotes vehicle in the horizontal plane from smashinn the center of gravity of the load, posted on gruzomobile, relative to its suspension point (axis).

The solution is achieved by the fact that in the suspension of protonotes vehicle, comprising a support mounted on it through axis grotonover and mechanism of equilibration of protonotes about its axis, made in the form of two shoulders of the lever mounted on the support vehicle and interacting one-shoulder with gruzomobile, two shoulders, the other lever shoulder interacts with the axis of protonotes.

The invention is illustrated by drawings, where

figure 1 shows the suspension of protonotes vehicle;

figure 2 is a view As in figure 1;

figure 3 - cross-section B-B in figure 2;

figs.4 and 5 - suspension of protonotary vehicles with grushovtsy mounted on a support by means of a separate axes;

figure 6 - suspension of protonotes vehicles operating on her forces from placed her cargo in Cartesian coordinates.

Suspension of protonotes vehicle comprises a support 1, a swivel mounted on it by means of a 2-axes or axes 3 grotonover 4, and the axis 2 can be made as separate axes 3 and axis 2 or axis 3 can be rigidly mounted or on a support 1 of a vehicle, or on gruzomobile 4 or freely set the relative bearing 1 and protonotes 4, and the balancing mechanism of protonotes 4 about the axis 2. The mechanism of equilibration of protonotes axis 2 rotation from exposure to grotonover 4 offset of the center of gravity of the load 5, posted, made in the form of two shoulders of the lever 6 mounted on a support 1 of a vehicle in the area of the end wall of protonotes 4 and interacting one-shoulder with gruzomobile 4, and the other with the axis 2.

Two shoulders lever 6 can interact with gruzomobile 4 by means of a groove made on the end wall of protonotes 4 with the axis (or eccentric, or lowering device)installed on one of the two shoulders shoulders of the lever 6, or Vice versa. Similarly, two shoulders lever 6 interacts with the axis 2. Grotonover 4 is installed on the support 1 so that its deviation from the horizontal plane about the axis 2 is not allowed. Two shoulders lever 6 can be mounted on a support 1, either above or below or at the same level relative to the axis 2.

With a relatively large length of protonotes 4 suspension of protonotes vehicle may be equipped with two mechanisms balancing of protonotes axis 2 and they can be installed in areas of the face walls of protonotes 4.

The work of the suspension of protonotes vehicle consider figure 6. On grotonover 4 is actuat gravity of the load 5, moreover, the center of gravity of the load 5 is displaced relative to the axis 2.

According to the rule of parallel power transfer will transfer the force of gravity G of load 5 to the vertical passing through the center (point O) 2-axes suspension of protonotes 4 and through the center (point O2) the axis of the two shoulders of the lever 6, and the action shifted the centre of gravity of load 5 replace point M. let us Consider the equilibrium of protonotes 4 cargo 5 axis 2 at the point O under the action of gravity G of the load 5 at a point On the reaction R occurs, equal and oppositely directed force of gravity G. Under the action of the moment M grotonover 4 cargo 5 tends to turn about the axis 2 rotation in the point O, and grotonover 4, interacting with one of the two shoulders shoulders of the lever 6 at the point O1seeks to expand the latter relative to the point O2but since the second shoulder, two shoulders of the lever 6 interacts with the axis 2 in the point O, the point O is a reaction R1and at the point O1- R2and the reaction of R1and R2equal and oppositely directed, because the shoulders O1O2and O2About equal. Thus, the sum of the forces with respect to the axis "Y" is equal to zero, the sum of the forces with respect to the axis "X" is equal to zero and the sum of the moments about point O is equal to zero, since the reaction of R2equal to the ratio M/OO1and the moment M and torque reaction R2shoulder OO1equal and p is otvoreno directed.

Therefore, grotonover 4 cargo 5 are in balance about point O, i.e. the axis 2.

Thus, the proposed technical solution constructively simple, reliable and convenient in operation, enables the installation of protonotes on a horizontal support, abolishes the operation including centering of the load relative to the axis of the installation of protonotes, i.e. the axis of suspension of protonotes vehicle, and can be used in ground (pipelines, trucks, rail transport etc), by air, sea and river transport.
