The alleged invention relates to mechanical engineering and can be used in the construction of rail and road vehicles.

Known damper (for example, a hydraulic damper), represented As the USSR №1084508. This damper consists of a working cylinder, in which is movably placed a piston, mounted on an elastic rod of circular cross section. The piston at its end surface provided with radially arranged ribs adjacent to the gap to the lugs, which are provided with horizontally spaced channels that extend in the vertical. When moving the piston, the working fluid passes through the channels and leaving them creates a torque on the piston rod, thereby ensuring that when the spin damping oscillations. A significant drawback of such a damper is that it is the oscillation only when working stroke of the piston, and in return creating a torque on the shaft does not occur.

Also known damper described in patent RU 2230241, in which the piston consists of two parts, and each of them is rigidly attached to their stems, one of which is made hollow with a circular cross-section, and another solid round cross-section. Each of the halves of the piston has a radially arranged ribs adjacent to the gap to the lugs, provided G is breznay form channels. The work of this damper compared to similar more efficient, but it conveys an important disadvantage in that the angular deformation of elastic rods when working stroke and the return are handled separately, and it affects the underutilization of the damping characteristics of the damper.

Therefore, the aim of the invention is the expansion of the damping ability of the damper.

This objective is achieved in that the two parts of the piston is made in the form of glasses, provided with a mating between a pair of radially spaced walls and rigidly mounted on the hollow piston rod of circular cross-section, and the interior of the cups between their radial partitions placed the movable blade is rigidly connected to a solid rod of circular cross section, and in the bottoms of the aforementioned glasses are made of throttle channels of different diameters.

Figure 1 shows a General view of the damper in section, figure 2 is a view of one of the glasses in the direction of arrow a in figure 3 - view of the other glasses on the arrow In figure 4 - General view of the blade in perspective, figure 5 - view of the end portion of the hollow rod of circular cross-section in perspective and figure 6 - cross section of a damper on the SS.

The damper consists of the working cylinder 1 in which is placed a piston consisting of the upper Cup 2 and the bottom of the Cup 3, and between n the mi movably placed the blade 4. The glasses 2 and 3 provided with radial partitions 5 and rigidly fixed respectively with the pins 6 on the hollow piston rod of circular cross-section 7, which has Windows 8 for placement of the blade 4. The blade 4 with the pins 9 are installed on a solid rod of circular cross section 10. In the bottom of the Cup 2 is made of throttle channels 11, 12, 13, 14 and 15, and in the bottom of the Cup 3 - throttle channels 16, 17, 18, 19 and 20. A working cylinder filled with working liquid 21.

Does the damper as follows. When driving, for example, rods 7 and 10 together with the glasses 2 and 3 by the arrow E. the working fluid 21 flows into the throttle channel 16 in the direction of arrow G and through it in the cavities of the bottom 3 and top 2 glasses, while the generated pressure of the working fluid 21 in the space between the blade 4 and radially spaced walls 5 cups 3 and 2 will create a circumferential force P acting on the blade 4, and radially arranged partitions 5 (see Fig.6). Under the influence of such efforts, the blade 4 will receive the angular rotation according to the arrow F, tying it at some angle a solid rod of circular cross section 10 and the hollow stem of the ring section 7 by the arrow K. as the rods 7 and 10 made of elastic material, they steppinout the load applied to the rods 7 and 10 by the arrow E. at the same time under the working fluid 21 in the space of the top 2 the bottom 3 cups, limited also by the blade 4 and their radial walls 5, will be let out through the throttle channel 11 in the direction of arrow M in nadporshnevaya cavity of the working cylinder 1. Current working fluid 21 through the throttle channel 11 will also occur with the creation of the forces of resistance to movement of the piston. If the load acting on the arrow E, will be more significant value, in this case, the blade 4 will receive more in direction of the arrow F of angular rotation, and then opens the part throttle channels (17-20), and channels (12-15), which will create conditions to ensure smoother movement of the piston, characterized by its slow and after a greater speed of working fluid 21 through the throttle channel 11 in the direction of arrow M, the Angular displacement of the blades 4, and the upper Cup 2 and the bottom of the Cup 3, collectively and in relation to each other, and hence twist hollow rod ring sections 7 and a solid rod of circular cross section 10 in a wide range of effects on the dynamic damper components of efforts will allow it to automatically adjust the resistance forces, providing as a result, the smoothness of the crews during their movement both on the track and roads, with complex micro - and macroprofile.

Techno-economic advantages of the proposed technical solution in comparison with known who Tim obviously, because its damping harakteristiki more effective due to the current distribution of fluid through the throttle channel and use simultaneously different in the direction of the angular rotations of the rods and their elastic properties.

The damper containing a working cylinder which houses the piston, which consists of two parts rigidly mounted on the hollow or solid rods, respectively, a ring and a solid circular cross-section, and provided with channels for the passage through them of the working fluid, characterized in that the two parts of the piston is made in the form of glasses, provided with a mating between a pair of radially spaced walls and rigidly mounted on the hollow piston rod of circular cross-section, and the interior of the cups between their radial partitions placed the movable blade is rigidly connected to a solid rod of circular cross section, and in the bottoms of the aforementioned glasses are made of throttle channels of different the diameter.
