Push rod five-sliding-teeth transmission four-cylinder internal combustion engine

Abstract

The invention discloses a push rod five-sliding-teeth transmission four-cylinder internal combustion engine, and relates to the field of transmission of an internal combustion engine. The internal combustion engine solves problems that an existing crankshaft connecting rod internal combustion engine is large in volume, easy in eccentric wearing, high in energy consumption, low in power, and high in manufacturing precision. A machine body of the push rod five-sliding-teeth transmission four-cylinder internal combustion engine is fixedly provided with an active rotating shaft and a driven rotating shaft through a bearing. The driven rotating shaft is provided with a driven sliding-teeth disk which has the same shape and size with an active sliding-teeth disk on the active rotating shaft. Active sliding-teeth and driven sliding-teeth are respectively one tenth of perimeters of the active sliding-teeth disk and the driven sliding-teeth disk. One side of the active sliding-teeth disk is provided with a first air cylinder and a third air cylinder, and one side of the driven sliding-teeth disk is provided with a second air cylinder and a fourth air cylinder. The four-cylinder internal combustion engine is simple in structure, small in volume, low in cost, easy in maintenance, and low in energy consumption, and the four-cylinder internal combustion engine prevents eccentric wearing and effective power is greatly improved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine transmission, in particular to a four-cylinder internal combustion engine with push rod five movable teeth transmission. Background technique [0002] At present, the traditional piston internal combustion engine mostly uses the cylinder as the power unit. The piston is connected with the crankshaft through the piston pin and the connecting rod. The crank connecting rod is used as the transmission device. The connecting rod is connected with a flywheel. Rotation; In order to inhale fresh gas and discharge exhaust gas, there are intake valves and exhaust valves. The farthest distance between the piston top and the center of the crankshaft is called the top dead center, and the place where the piston top is closest to the center of the crankshaft is called the bottom dead center. Relying on the expansion force generated by the combustion of mixed oil and gas in the cylinder to do ...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the internal combustion engine uses the connecting rod crankshaft to convert the reciprocating motion of the piston into a circular motion, when the compression stroke of the cylinder ends, that is, at the top dead center of the expansion power stroke, the mixture in the cylinder is burned to make the pressure in the cylinder maximum and produce the strongest Thrust, but at this time in the crank-link mechanism, the crankshaft and the connecting rod are in a straight line, that is, the moment arm is zero, that is, there is no power output at this time, that is, no work is done to the outside; and the circular motion of the crankshaft will inevitably cause the connecting rod connected to the crankshaft to The included angle changes, the power is widely distributed, and only part of the power can be transmitted, so the crankshaft and connecting rod mechanism makes the heat utilization rate of the internal combustion engine very low;

[0004] 2. The angle between the connecting rod and the moving direction of the piston will cause a certain amount of friction between the piston and the inner wall of the cylinder block. The larger the angle between the connecting rod and the moving direction of the piston, the greater the friction. The friction force generated by the wall is uneven, so after the piston moves at high speed for a long time in the cylinder, it is easy to cause eccentric wear, which will damage the inner wall of the cylinder or the piston and cause air leakage, so that the heat utilization rate of the internal combustion engine will decrease. The problem that has not been solved since the use of the rod internal combustion engine;

[0005] 3. The upper part of the crankshaft connecting rod internal combustion engine body where the cylinder is installed and the lower part where the crankshaft and crankcase are installed are combined for integral casting. Because the coordinated operation of the various components in the crankshaft connecting rod internal combustion engine requires the crankshaft connecting rod internal combustion engine body The design of each part of the internal combustion engine has extremely high precision, especially the strict requirements on the position, shape and size of each cylinder and crankshaft in the internal combustion engine body, which will inevitably lead to the difficulty of processing and producing high-precision integrally cast crankshaft connecting rod internal combustion engine body Because the body of the internal combustion engine is formed by integral casting, once the damage of the body of the internal combustion engine is caused by a certain cylinder damage, then the whole body of the internal combustion engine is just scrapped and needs to be replaced, so that other components such as crankcases that are not damaged in the body of the internal combustion engine are also abandoned. cause waste;

[0006] 4. The cylinders of the internal combustion engine and the crankshafts corresponding to the cylinders are arranged in a straight line. The linear arrangement of the crankshafts will inevitably lead to an increase in the volume of the internal combustion engine, which will also increase the volume of the transmission components in the internal combustion engine, and the various components in the internal combustion engine will increase accordingly. The result of the increase is that the friction force when the internal combustion engine is running also increases, which means that the energy consumption of the internal combustion engine also increases when the internal combustion engine is running.
