Abstract
The invention provides a four-stroke opposed engine. Two round slide blocks (6) are mounted on the middle straight line of the four-stroke opposed engine in an opposed manner; guide rails (4) are mounted on the upper tip circles and the lower tip circles of bearings (8); connecting rods (10) are fixed with a frame body (7) through cylindrical pins (9), and are fixed with pistons (1) through piston pins (2); the two pistons (1) are mounted on the middle straight line of the four-stroke opposed engine in an opposed manner, so that the opposed pistons (1) are on the same straight line; the connecting rods (10) are mounted on the middle straight line of the four-stroke opposed engine in an opposed manner, so that the opposed connecting rods (10) are on the same straight line. The four-stroke opposed engine works on the same straight line by taking the main shaft diameter of a crank shaft as a unit in an opposed manner, and the opposed pistons are on the same straight line, so that the linear transmission moment is large, and the power consumption of stroke conversion is low.
Description
Technical field
The present invention relates to engine art, relate in particular to a kind of four-stroke contraposition engine.
Background technique
The prior art four stroke engine is because connecting rod and piston are curvilinear motions, so can produce shearing force between connecting rod and the cylinder sleeve during motor acting, consumes the power that acting produces, and engine components are produced damage.
Summary of the invention
The purpose of this invention is to provide a kind of four-stroke contraposition engine, the shearing force in the time of can reducing the motor acting between connecting rod and the cylinder sleeve.
In order to solve the problems of the technologies described above, four-stroke contraposition engine provided by the invention is achieved in that
A kind of four-stroke contraposition engine opposedly on the straight line of the middle part of described four-stroke contraposition engine is equipped with two smooth blocks 6; Guide rail 4 is installed in upper tip circle and the lower tip circle place of described bearing 8, and connecting rod 10 is fixing by straight pin 9 with described framework 7, and described connecting rod 10 is fixing by wrist pin 2 with piston 1; Described piston 1 is opposed on the straight line of described four-stroke contraposition engine middle part to be equipped with two, and described opposed piston 1 point-blank; Described connecting rod 10 is opposed on the straight line of described four-stroke contraposition engine middle part to be equipped with two, and described opposed connecting rod 10 point-blank.
Optionally, described framework 7 and bearing 8 interference fit, the cylindrical of described framework 7 and described bearing 8, described connecting rod 10 and described piston 1 are made the straight line motion of X coordinate; The inner circle of described smooth block 6 is rotated around the connecting rod journal diameter of described bent axle 5, and the cylindrical of described smooth block 6 is made the straight line motion of Y coordinate in described framework 7 oblong aperture.
Four-stroke contraposition engine provided by the invention, take crankshaft main-shaft diameters opposed acting point-blank as the unit, opposed piston point-blank, Linear transmission moment is large, stroke conversion power consumption is few.Motor can be with respect to crank angle.
Description of drawings
Fig. 1 is the sectional view of four-stroke contraposition engine provided by the invention.
Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of four-stroke contraposition engine opposedly on the straight line of the middle part of four-stroke contraposition engine is equipped with two smooth blocks 6; Guide rail 4 is installed in upper tip circle and the lower tip circle place of bearing 8, and connecting rod 10 is fixing by straight pin 9 with framework 7, and connecting rod 10 is fixing by wrist pin 2 with piston 1; Piston 1 is opposed on the straight line of four-stroke contraposition engine middle part to be equipped with two, and opposed piston 1 point-blank; Connecting rod 10 is opposed on the straight line of four-stroke contraposition engine middle part to be equipped with two, and opposed connecting rod 10 point-blank.
Wherein, framework 7 and bearing 8 interference fit, the cylindrical of framework 7 and bearing 8, connecting rod 10 and piston 1 are made the straight line motion of X coordinate; The inner circle of smooth block 6 is rotated around the connecting rod journal diameter of bent axle 5, and the cylindrical of smooth block 6 is made the straight line motion of Y coordinate in framework 7 oblong aperture.
Four-stroke contraposition engine provided by the invention, take crankshaft main-shaft diameters opposed acting point-blank as the unit, opposed piston point-blank, Linear transmission moment is large, stroke conversion power consumption is few.Motor can be with respect to crank angle, and for example four-stroke four cylinders 90 are spent, four-stroke eight cylinders 45 degree.
Four-stroke contraposition engine provided by the invention take crankshaft main-shaft diameters as the unit, has formed so the two ends piston linear is opposed, left side four-stroke working state be " advance, pressure, quick-fried, row "; The right four-stroke working state is " press, quick-fried, arrange, advance ".Frame bearing is limited its degrees of freedom during acting by upper and lower guide rail, makes it can only be along the guide rail straight line motion.Greatly reduced the shearing force of connecting rod countercylinder cover with respect to conventional engines.Make whole process " row is steady, shearing is little, it is light to shake, moment of torsion is large ".
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
