Cylinder double-face cam axial piston type crankless internal combustion engine

Abstract

The invention discloses a cylindrical double-track cam axial piston type crankless internal combustion engine, which relates to the technical field of internal combustion engines and is a multi-cylinder internal combustion engine. The invention provides a novel internal combustion engine; when pistons drive rollers arranged on the bottoms of the pistons for reciprocating movement, the rollers push a double-track cam fixed on a main shaft to rotate, and the power is output from the double-track cam through the main shaft. Outlines of two end surfaces of the double-track cam are in the form that wave crests correspond to wave crests, wave troughs correspond to wave troughs, and the two end surfaces are circumferentially symmetrical. Two groups of cylinders are symmetrically arranged at bothends of the double-track cam, and axis lines of the cylinders have equal distance to an axis line of the main shaft and are parallelly, circularly and evenly distributed. The pistons which have the same axis line and are symmetrically arranged with the spacing of 180 DEG C have the same working state, which ensures that the axial and radial composite force of the double-track cam and the main shaft are zero. A sliding rod at the bottom of each piston slides in a guide groove, which ensures that the side pressure of the piston is zero. Intake and exhaust valves of all the cylinders are intensively controlled by two distributing cams. The internal combustion engine has the characteristics of simple and compact structure, small volume, small impact vibration, steady operation, high power, long service life and so on.

Description

technical field [0001] The invention relates to a cylindrical double-sided cam axial piston type internal combustion engine without a crankshaft, which belongs to the technical field of internal combustion engines. Background technique [0002] At present, most of the reciprocating internal combustion engines used at home and abroad are four-stroke crankshaft connecting rod type internal combustion engines, which convert the reciprocating movement of the piston into the rotation of the crankshaft by the crank connecting rod mechanism and output power. The main disadvantages of this internal combustion engine are: large volume; the piston has a large side pressure on the cylinder wall, which causes large mechanical wear and shortens the life of the internal combustion engine; the unbalanced centrifugal force on the crankshaft is large; the impact is large, vibration Usually, the intake and exhaust system of an internal combustion engine includes a long camshaft and multiple v...
