The invention relates to various branches of engineering and construction, using the frame as a support member under the units and motors and elements transmissions (JG the gas industry, that is, in the General and special mechanical engineering.

In the construction of the NOC can be used as load-bearing elements of bridges, load-bearing beams of various cranes, beams of buildings and structures and in the building-road technics.

Known support for the elevating mechanism consisting of a symmetrical box beam with parallel sides, and between the beams entered the link adjacent to the beams on the side opposite the side on which the impact of efforts wind load (application Germany N 1224011 from 1966, IPC 6 B 66 C 6/00).

Also known bridge farm crane, consisting of the main and sub beams in the cavity of the box girder by welding reinforced elements that increase its strength against twisting and buckling (patent of Russian German N 2853658 from 27.01.1983 , IPC 6 B 66 C 6/00).

The existing load-bearing elements of the above structures are designed for a maximum load corresponding reserves of strength, which operated bearing elements are, as a rule, very rarely, but the weight of the ballast are constantly expending energy on their transportation.

Founded physical specifications goes about the vehicle.

Known shell design - traction body lift, adopted for the prototype, containing enclosed in a shell of a Central plate (USSR author. St. N 644704 from 30.01.79, IPC 6 B 66 B 15/02).

Bearing capacity of known construction does not provide stability of the side walls is proportional to the external loads.

Technical task, which directed the claimed design is to provide a proportional increase resistance of load-bearing beams or elements of the traction unit (transmission) with increasing external load summation of the effect of increasing the stability, reducing the risk of excitation of self-oscillations, with the ability to perceive twisting effort.

The problem is solved in that hard shell structures containing enclosed in a metal and an elastic shell center plate, it is surrounded by the side plates with their inherent positive radius of curvature relative to the pivot plate, the shell can be placed several center plates and side pairs, the center plate can be mounted either vertically relative to the outer support plate, and the attributes in resemebles set, the shell may be equipped with a strain gauge associated reverse positive correlation with the pressure source.

The invention is illustrated by drawings, where Fig. 1 - shows a cross-section of the shell of Fig. 2 is a longitudinal section of the shell of Fig. 3 - bearing shell, Fig. 4 is a longitudinal section of the shell with center plates, arranged at an angle.

Hard shell design contains enclosed in metal 1 and the elastic membrane 2 center plate 3. The center plate 3 is closed the side plates 4 with a set of positive radius of curvature relative to the pivot plate, and the flexible sheath 2 is under a preliminary pressure from the inside.

To reduce the risk of excitation of self-oscillations of the center 3 and side 4 of the plate is made with a damping coating or composite resemebles set.

To ensure the ability to perceive twisting the efforts of the center plate 3 can be installed at an angle from 0 to 45o.

The work of the NOC begins with submission to the working of the external load, which will begin to deform the center plate 3, to the plane of the center plate 3 distributed pressure in elastic sealed casing 2. A positive radius of curvature of the side plate 4 relative to the center plate 3 provides conditions under side backwater elastic camera stabilization sustainability center plate 3 due to the inclusion in work side by plates 4. Thus, conditions are created to summarize the effect of increasing the carrying capacity of the shell 1, as beams, at different load types, including those that are particularly important for the transport systems, to perceive and vibratory loads. It should be noted that the side plate 4 can be stackable in resemebles option, which creates conditions to perceive external load, proportional to lateral pressure on the side plate 4.

Resemebles side plates will reduce the possible risk of inciting the self-oscillatory processes in both stationary and transport options of the bearing shell 1.

In the extreme case of increasing external load sensor 5 mounted on the shell 1, the sensing of the changing nature of the external load, gives a signal to the pressure source 7 through the reverse positive relationship 6, when this is activated the pressure source, increases the lateral compression of the side plates 4 of the center plate 3 is e stability of load-bearing beams or elements of the traction body (powertrain).
