Abstract

The invention discloses a series connection non-crankshaft engine transmission mechanism which comprises a power shaft and an auxiliary shaft. At least two air cylinder piston rods are arranged between the power shaft and the auxiliary shaft. Air cylinder pistons are arranged at the end heads of the same ends of the air cylinder piston rods correspondingly. One side of each air cylinder piston rod is engaged with a main gear which is arranged on the power shaft in a sleeving manner through a one-way clutch. The combining directions of the one-way clutches are the same. The other side of each air cylinder piston rod is rotationally connected with the auxiliary shaft through a guiding mechanism. Every two adjacent two main gears are in transmission connection through a reverse transmission mechanism. When one air cylinder piston rod acts, the corresponding main gear rotates, and when the combining directions of the one-way clutches are the same, the main gears corresponding to the power shaft enable the power shaft to rotate to output power through the corresponding one-way clutches. Meanwhile, transmission and reversing of power needed by the stroke of the corresponding air cylinder piston rods are achieved by every adjacent two main gears through the corresponding reverse transmission mechanisms. The transmission mechanism belongs to a free piston type, and therefore a variable compression ratio function is achieved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a serial crankshaftless engine transmission mechanism and an engine with the same. At the same time, it has the function of adjustable compression ratio. Background technique [0002] A common engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The expansion of the gas pushes the piston to do work, and then the mechanical work is output through the crank connecting rod mechanism to drive the driven machine to work. [0003] Adopting the crankshaft-connecting rod mechanism has also become a classic structure of power transmission; but there are still many shortcomings in this mechanism. Low mechanical transmission efficiency: the force of the gas acting on the piston is transmitted to the crankshaft through the connecting rod, and two component forces are generated at the connect...
