Description

The invention relates to mechanical engineering, in particular to engine building, namely to rotating internal combustion engines, and can be used in the automotive industry, aircraft construction.

A known internal combustion engine (application RU No. 2002121198, IPC F02B 57/00, publ. 04/10/2004) containing a rotating cylinder block with opposed pistons with support rollers, a nozzle pump and a gas distribution system. The rotating cylinder block is connected to the drive wheels through a central gear wheel, which is connected to the crankshaft satellites through connecting rods with pistons. The engine is located in the drive wheel of the vehicle.

A disadvantage of the known engine is that it is rotational and has a low efficiency and low engine life, as a result of which rotary engines are not widely used. In the known engine, the rotating cylinder block is connected to the drive wheels through a central gear wheel, which, in comparison with the invention, is an additional link and provides additional engine mass. The disadvantage is also the small liter volume of the cylinders and the large size of the engine due to the opposed arrangement of the pistons.

The closest in design and purpose is the two-row twin-shaft internal combustion engine adopted as the prototype (Design Fundamentals. Reference and methodological manual, book 1, third edition, edited by P.N. Uchaev. - M.: "Engineering" 1988, p.37 , item 11). This engine contains two cylinder blocks located parallel to each other and to the axis of the central gear wheel, two crankshafts, on which small gears are located through which the movement is transmitted to a large gear mounted on a central rotating shaft. Two gears are located on the shaft - large and small. Parallel to the shaft axis and symmetrically to each other, two engine parts are placed, each of which contains a crankshaft, on which, as a rule, one gear is installed, which is two times smaller than the larger gear of the main shaft.

The disadvantage of this engine is that it has large dimensions and weight, as well as the inability to place it in the drive wheel of the vehicle.

The objective of the invention is the ability to place the internal combustion engine in the drive wheel of the vehicle and, as a result, reduce the weight of the vehicle, increase the efficiency of the vehicle, as well as increase the reliability of the engine.

The essence of the invention is as follows. A rotating internal combustion engine comprises a housing, two cylinder blocks located in the housing, a crank mechanism, a central shaft. The shaft is made to rotate about its axis. As a rule, two gears are placed on the shaft - a small one that transmits torque to the gearbox, and a large one connected to the gears of two crankshafts parallel to the axis of the central shaft. Each crankshaft is connected through a movable connecting rod to a piston mounted in the cylinder with the possibility of reciprocating motion. The cylinder blocks are placed parallel to the axis of the central shaft and parallel to each other.

Unlike the prototype, one cylinder block with its crank mechanism is placed in parallel and rotated 180 ° in space relative to the other cylinder block with its crank mechanism. This arrangement of engine parts ensures that the engine is balanced and does not create vibration during operation. The engine has an optimal number of cylinders, is easy to manufacture and has sufficient engine life.

The engine is rotatable relative to the rotating central shaft.

The engine is located in the drive wheel of the vehicle. The engine housing is a drive wheel drive of a vehicle.

The internal combustion engine is illustrated by graphic materials, in which Fig. 1 schematically shows a cross section of the inventive internal combustion engine located in the wheel disk of a vehicle, in Fig. 2 is a top view, in Fig. 3 is a crank mechanism.

The internal combustion engine comprises a central shaft 1 rotatable relative to its axis. Two gears are installed on the central shaft - large 2 and small 3. Parallel to the shaft axis and two each other are two engine parts, each of which contains a crankshaft 4 on which it is mounted gear 5, which is usually half the size of the large gear 2 of the central shaft. The crankshaft 4 is connected through a connecting rod 6 to a piston 7 located in the cylinder 8. The housing 9 of the engine is the drive disk of the vehicle 10.

A rotating internal combustion engine operates as follows.

The combustion of fuel is carried out in cylinders 8, while thermal energy is converted into mechanical energy. Under the influence of the pressure of the generated gases, the reciprocating movement of the piston 7 occurs. The reciprocating movement of the piston 7, in turn, is converted into rotational motion of the crankshaft 4 of the engine through the connecting rod 6, which is the connecting link between the cylinder 8 with the piston 7 and the crankshaft 4. From the crankshaft 4 through the gear 5, rotational movement is transmitted to the large gear 2 of the central shaft 1. Then, through the small gear 3 of the central shaft 1, the torque is transmitted to the speed gearbox (not azana) and rotates the engine casing 9 together with the wheel 10.

The proposed constructive solution of the inventive rotating internal combustion engine in comparison with the prototype will allow you to place it in the wheel drive of the vehicle and reduce the weight of the vehicle by 25-30%, increase the efficiency of the vehicle by 50%.
