Rack crankshaft variable speed transmission internal combustion engine

Abstract

The invention discloses a rack crankshaft variable speed transmission internal combustion engine. The rack crankshaft variable speed transmission internal combustion engine comprises a cylinder, a crankshaft, a connecting rod, a gear, a rack, an output shaft, an engagement piece, a first transmission wheel and a second transmission wheel; the cylinder comprises a cylinder block, a piston and a piston rod; a combustion chamber is arranged in the cylinder block; one end of the piston rod is connected with the piston, and the other end of the piston rod is connected with the rack; one end of theconnecting rod is movably connected with the rack, and the other end of the connecting rod is movably connected with the crankshaft; the engagement piece sleeves the output shaft or the crankshaft, and forms radial transmission and axial movable connection with the output shaft or the crankshaft; the first transmission wheel is arranged on the output shaft; the second transmission wheel is arranged on the crankshaft; the gear is engaged with the rack; the gear is arranged on the output shaft; and an overrunning clutch is arranged between the gear and the output shaft. The variable speed outputof the output shaft is realized.

Description

【Technical field】 [0001] The invention relates to the field of internal combustion engines, in particular to a rack crankshaft transmission internal combustion engine. 【Background technique】 [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. The reciprocating piston internal combustion engine is the most common type of piston internal combustion engine. The piston internal combustion engine mixes fuel and air and burns it in its cylinder. 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 passes through the crank connecting rod. The mechanism outputs the mechanical work to drive the driven machine to work. [0003] An internal combustion engine generally includes: a cylinder, a crankshaft, a connecting rod, a piston and a combustion cha...
