The invention relates to mechanical engineering, in particular the hydrodynamic transmission of torque.

Known integrated torque converters containing symmetrical to each other of the pump and the turbine wheel and the axial reactor associated with the stationary shaft through the mechanism of free running (see Weepers and Waitron. Hydrodynamic transmission cars. M: motor cycle", 1961, pp.93-98). They have a mode of operation as with the transformation of torque, and without transformation, efficiency, striving for 100% (transformation mode and the mode of fluid coupling). However, the total operating range of the integrated torque Converter (transformation mode plus mode fluid coupling) with an acceptable efficiency does not exceed 2, while for rail vehicles it shall be not less than 5 (Iframeaction. Hydraulic transmission locomotives. M: motor cycle", 1961, p.7), and for vehicles, of course, much more.

Known torque Converter Swedish company SRM with forced rotation of the reactor containing the pump wheel, unbalanced him a two-stage turbine wheel, centripetal reactor, planetary gearing connecting the reactor and the turbine wheel rotatably reactor in the direction opposite to the direction of rotation of the turbine wheel, and two band brakes, allowing you to slow down or to let in what came planetary gear unit or reactor. The specified torque Converter has an operating range of 4 (see S.R.M. Hydraulic Transmission, DRT, No. 330, 1959). Accepted as the closest prototype device of the same purposes of the claimed device on a set of attributes.

The obstacles to achieve the desired technical result when using the prototype, is that the asymmetry of its pump and turbine wheels does not allow for the transmission of torque without a transformation of its size (fluid coupling).

Summary of the invention in the following. The problem to which the invention is directed, is to expand the operating range of the torque Converter with forced rotation of the reactor.

This task is solved by the achievement of the technical result in the implementation of the invention to provide additional opportunities for simple transmission of torque without transformation (fluid coupling mode).

This technical result in the implementation of the invention is achieved by the fact that the proposed Converter with forced rotation of the reactor contains symmetrical to each other of the pump wheel and the turbine wheel, reactor, planetary gearing connecting the reactor and the turbine to rotate the wheels of the reactor in the direction opposite to healthy lifestyles is the rotation of the turbine wheel and brake, allows you to brake or release the carrier of the planetary gear and the reactor. When this pump wheel is made of centrifugal, turbine - centripetal and symmetric pumping, and reactor - axis.

Conducted by the applicant's analysis of the prior art, including searching by the patent and scientific and technical information sources, and identify sources that contain information about the equivalents of the claimed invention, allow us to conclude that it is not detected with similar characteristics that are identical to the characteristics of the claimed invention. The definition from the list of identified unique prototype as the most similar in purpose and essential features allowed us to identify significant distinguishing features in relation to the achieved by the invention technical result set forth in the claims.

Therefore, the proposed device meets the condition of "novelty". Additional search of the known technical solutions showed that the claimed invention is not apparent to the expert in the obvious way from the prior art because the prior art defined by the applicant, not the effect of the transformations provided the essential features of the claimed invention, to achieve a technical result.

Therefore, the claimed izaberete the s meets the condition of "inventive step".

On the accompanying drawing shows a kinematic diagram of the proposed Converter.

Information confirming the possibility of obtaining the above-mentioned technical result are as follows.

The torque Converter includes a centrifugal pump wheel 1 connected to the drive shaft 2, the symmetric him centripetal turbine wheel 3 connected with the output shaft 4, the axial guide device (reactor) 5, a planetary gear comprising a sun gear 6, the crown gear 7, satellites 8, 9 led, tape or disc brakes reactor 10 and the tape or disk brake carrier 11.

The torque Converter operates as follows.

In the initial operation of the brake 10 is released, the brake 11 is clamped, drove 9 motionless. When filling the torque Converter fluid and the centrifugal pump wheel 1 rotates centripetal turbine wheel 3 in the same direction as the centrifugal pump wheel 1. The axial reactor 5 under the action of a reactive moment starts to rotate in the direction opposite to the direction of rotation of the pump wheel 1 and centripetal turbine wheel 3. When this torque acting on the axial reactor 5 through 8 satellites is summed with the torque centripetal turbine wheel 3. So about the time, in the stop point, the torque on the output shaft 4 is increased in comparison with the torque on the pump wheel 1 810 times. When reaching the gear ratio of the torque Converter when the torque on the reactor 5 is approaching 0, the brake 11 is released and the brake 10 is clamped and the work is done, as in a conventional torque Converter. When reaching a ratio equal to 0.7, the brake 10 is released, the axial reactor 5, released the brake 10, rotates freely in the fluid flow, without exerting influence on him, and torque due to the symmetry of the turbine 3 and the pump 1 of the wheels is transmitted without transformation with high efficiency, that is, in the mode of fluid coupling, thereby operating range compared to the prototype increases from 4 to 5.

Thus, the invention allows to expand the range of efficient operation of the torque Converter in comparison with the prototype through the use of fluid coupling mode.

Therefore, the above data confirm that the implementation of the use of the claimed invention the following cumulative conditions:

the tool embodying the claimed invention in its implementation, is intended for use in industry to convert torque on the shafts;

for the claimed invention in the form as it is characterized in fo the mule of the invention, confirmed the possibility of its implementation using the steps described in the application of the funds;

the tool embodying the claimed invention in its implementation, is able to achieve perceived by the applicant of the technical result.

Therefore, the claimed invention meets the requirement of "industrial applicability".
