Description

 The invention relates to mechanical engineering, in particular to engine building, namely to rotary internal combustion engines, and can be used in power engineering, diesel locomotive, shipbuilding, aviation, and tractor and car manufacturing.

 Known methods for using compressed air exhaust and compressed gases in power transmissions: in gas turbines, power drives of blade machines (see, for example, the description of the invention to the patent of the Russian Federation RU 2056555 C1, 6 F 16 N 41/000, from 03.20.1996) , in the pneumatic systems of machines, turbochargers of internal combustion engines (see, for example, patent GB 1044176 A, F 02 B 37/00).

 These methods are highly specific and ineffective, unmanageable in changing rotation in direction and speed, in changing torque in magnitude of force and direction of action, which does not allow excluding from the kinematics of tractors, combines and other equipment of bulky gearboxes and rear axle differentials.

 As a prototype, it is proposed to adopt a well-known engine with a turbocharger using the energy of exhaust gases (patent GB 1044176 A, class F 02 B 37/00, publ. 09/28/1966), containing a distributor, separated by blades and placed in a hollow body with channels, supplying exhaust gases from a manifold with a valve on an axis controlled by a lever.

 The known design of the prototype use of energy of exhaust gases to bring the working bodies of the unit into rotation is uncontrolled by the speed of rotation of the latter, has no reversal of their course and changes in torque.

 The objective of the present invention is to increase the efficiency of the process of transferring energy from the exhaust gases of the internal combustion engine to the working bodies of the unit in order to achieve the possibility of changing their rotation speed, reversing the stroke, changing the torque required to vary during operation of the unit, without the presence of bulky gearboxes and differential rear axle.

 The technical result is achieved in that in units with rotary vane internal combustion engines, instead of nodes of a known power transmission, a rotary vane machine or other turbine installation is set in motion by exhaust gases coming through gas pipelines with control valves and a tee with blades on the controlled axis from exhaust manifolds of the internal combustion engine of the unit, and transmitting rotational movement to the chassis, power take-off shaft or other organs, changing their speed rashchenija, direction of rotation, the torque to the redistribution of its efforts on the shafts chassis without the presence of the gearbox and the rear axle differential.

 A comparable analysis with the prototype shows that the inventive method for using the exhaust gases of an internal combustion engine in a power transmission is characterized in that due to the design of the gas pipeline system with control valves, a tee with vanes on the controlled axis and a rotor-vane machine driven by exhaust gases and transmitting rotation on the chassis, the power take-off shaft of the unit or other working bodies, their rotation speed, stroke reversal, torque necessary to vary When operating without a gearbox and differential.

 Thus, the inventive method of using the exhaust gases of an internal combustion engine in a power transmission meets the criteria of the invention of "novelty."

 Comparison of the claimed solution not only with the prototype, but also with other technical solutions in this technical field did not allow us to identify in them the features that distinguish the claimed solution from the prototype, which gives the right to conclude that the criterion is "significant difference".

 The device for power transmission of energy of the exhaust gases of an internal combustion engine to the working bodies of the unit will look as follows.

 The power transmission of energy of the exhaust gases of the internal combustion engine to the working bodies of the unit contains at least one block of rotor-blade machines driven by exhaust gases, including one or more sections in the form (see Fig. 1, 2, 3, 4 , 5, 6) of a cylindrical housing (stator) 1, eccentrically located on the shaft 7 of the rotor 2, the blades 3 of which are mounted in its radial grooves 4 with the ability to move, two end caps 5 with bearings 6, mounting bearings 8, gas pipelines 9 without valve to section "a" and with valves 12, 13, 14 to sections “b”, “c”, “d”, gas pipelines 10 (from each section), bypass gas pipelines 11 with valves 18, 20, 22 to sections “b”, “c”, “g”, manifold 15 s valve 23, manifold 16 with valves 17, 19, 21, 24 and a silencer 27 connected to its end, gas reversal pipelines 25 and 26 with valves 28 and 29, tee 30 with vanes on a controlled axis, connected by a steering rod 31 (on not shown), a three-way stop valve 32 (associated with a brake pedal, which is not shown in the figures), a connecting pipe 33 connecting the power train to the exhaust ruboy internal combustion engine (which is not shown in the figures).

 So that when working in the power train there are no dead zones, its sections on the shaft 7 are shifted by 45 degrees relative to each other.

 The work of the power transmission of energy of the exhaust gases of the internal combustion engine to the working bodies of the unit will occur as follows.

The exhaust gases from the exhaust pipe of the internal combustion engine (not shown) through the connecting pipe 33, bypassing the three-way stop valve 32, and the tee 30 with blades on the controlled axis will move:
1. With a direct stroke (figure 1), gases move into the manifold 15 when the valves (in the direction of the gas) 23, 12, 13, 14, 17, 19, 21, 24 are open, and the valves 18, 20, 22, 28 , 29 are closed, through gas pipelines 9 they enter simultaneously into sections “a”, “b”, “c”, “d”, creating a parallel force on the blades 3. In this situation, the maximum torque with the minimum rotation speed develops on the working shaft 7. Next, the exhaust gases, turning the blades 3 in sections from the inlet to the outlet, exit into the gas pipelines 10, from which they enter the manifold 16, and from it through the muffler 27 go into the atmosphere.

 2. With a direct stroke (figure 2), when the valves 12, 13, 14, 17, 19, 21, 28, 29 are closed and the valves 18, 20, 22, 23, 24 are open, the gases from the manifold 15 come sequentially from section "a" to section "b", from section "b" to section "c", from section "c" to section "d", through the muffler 27 to the atmosphere. In this situation, the maximum rotation speed of the shaft 7 develops.

 3. During the reverse rotation of the shaft (figure 3), when the valves 23, 24, 18, 20, 22 are closed and the valves 28, 29, 17, 19, 21, 12, 13, 14 are open, the gases in parallel flow into the sections " a, b, c, d, the maximum torque develops at the minimum speed of rotation of the working shaft 7. With this arrangement of valves, the reverse rotation of the shaft 7 is achieved due to the fact that the gases through the gas reversal 26 enter the manifold 16 and then in the opposite direction through gas pipelines 10 and 11, through sections "a", "b", "c", "d", bringing their rotors into rotation, and through gas pipelines 9 to collectors OR 15, from which the pipeline through reverser 25 enter the muffler 27, and out into the atmosphere therefrom.

 4. With the sequential inclusion (Fig. 4) of sections "a", "b", "c", "g" to reverse the rotation of the shaft 7, its rotation speed develops as much as possible when the valves 23, 24, 12, 13, 14, 17 , 19, 21 are closed, and valves 28, 29, 18, 20, 22 are open.

 Options for grouping valves into control units may be different to obtain a wider range of speeds of rotation of the working shaft 7.

 In FIG. 5 shows a section of a section of a rotor-blade machine along the axis of the working shaft 7. In a cylindrical body (stator) 1, a rotor 2 is mounted on a shaft 7 suspended on bearings 8, in which radial grooves 4 are mounted plates 3 with the ability to move. Using covers 5 and bearing assemblies 6, the rotor 2 has the ability to rotate around its axis.

 In FIG. 6 shows a section of a section of a rotor-blade machine perpendicular to the axis of rotation of the rotor 2, and also shows the installation location of gas pipelines 9 and 10 in the housing (rotor) 1.1
