Internal-combustion engine with two-phase inner cam shock wave shifting for transmission

Abstract

The invention relates to an internal-combustion engine with two-phase inner cam shock wave shifting for transmission, relates to the field of gas power, and belongs to a multi-cylinder internal-combustion engine. The invention provides a novel internal-combustion engine, wherein eight air cylinders are symmetrically uniformly distributed on the periphery of a two-phase inner cam in an annular manner, the stressed resultant force of a convex inner two-phase inner cam is zero, an air cylinder piston is directly acted on the convex inner two-phase inner cam through a push rod, and power is passed on an output shaft connected with a center wheel key through two-phase inner cam shock wave moving teeth of the convex inner two-phase inner cam. In the internal-combustion engine, a connecting rod and a crank shaft of the traditional internal-combustion engine are omitted, and a convex inner two-phase inner cam shock wave shifting transmission mechanism has no eccentric quality, has inertia force and service load self balancing; and the rotation speed of the output shaft depends on the transmission ratio of the living teeth transmission, if a living teeth frame is fixed, a center wheel outputs at a low speed in a large torque, and the internal-combustion engine is broadly used to project machines, armored cars and the like which need high power. The internal-combustion engine provided by the invention has the advantages that the structure is simple and compact, the axial size is small, the stressing is self-balanced, and the operation is stable.

Description

technical field [0001] The invention relates to the field of gas power, more specifically, a two-phase internal-cam shock wave moving transmission internal combustion engine. Background technique [0002] At present, a general internal combustion engine (engine) is composed of a body, a crank connecting rod mechanism, a gas distribution mechanism, a cooling system, a lubrication system, a fuel system, and an ignition system. stroke. The transmission mechanism of this type of internal combustion engine uses a crank-connecting rod mechanism, which transmits the power of the piston to the crankshaft through the connecting rod, and converts the reciprocating linear motion of the piston into the rotary motion of the crankshaft. Because this internal combustion engine presses and drives the crankshaft to rotate by the linear motion of the piston and the planar motion of the connecting rod, there is greater friction between the kinematic pairs, resulting in low transmission effici...

AI Technical Summary

Problems solved by technology

Since this kind of internal combustion engine relies on the linear motion of the piston and the plane motion of the connecting rod to press and drive the crankshaft to rotate, there is a large friction between the motion pairs, resulting in low transmission efficiency of the internal combustion engine.

These existing crankshaft connecting rod type internal combustion engines also have the following main disadvantages: large volume; the unbalanced centrifugal force on the connecting rod and the crankshaft is relatively large; the impact is large and the vibration is large; and thus cause large mechanical wear and shorten the life of the internal combustion engine; Complex structure, difficult processing, manufacturing, assembly, etc.

[0003] In addition, usually the internal combustion engine and the transmission device are two independent machines, and the internal combustion engine needs to be equipped with a transmission for subsequent speed change, resulting in a bulky
