Description
Technical field
The utility model belongs to technical field of internal combustion engines, relates to a kind of internal-combustion engine, particularly a kind of connecting rod guiding stroke piston combustion engine.
Background technique
The crankshaft ﹠ connecting of traditional combustion engine, connecting rod is done the wiggly compound movement in plane along with bent axle rotates, owing to be subjected to the relation of force direction, the power that conventional linkage is transmitted, must be that the lateral pressure of the cylinder pressure that gets off on the piston and cylinder wall is synthetic transmits by the power of connecting rod shank, the generation of huge lateral force (by cylinder-firing pressure, connecting rod and wall angle definite value) is one of the main killer in piston-cylinder group life-span, also causes the loss of a large amount of mechanical works simultaneously; The reciprocal inertia force of piston set generation simultaneously, can't be by single balance (crank throw balancer weight) complete equilibrium), and adopt the two balance modes of trunnion shaft, and often bring limitation that gear connects problem such as noise and layout often additionally by producing the part moment of torsion again, structure is also complicated.
" internal-combustion engine " 1981 the 8th phases were reported the no connecting rod type internal combustion engine of Japanese industry university development, the employing double-slider is used in combination, cylinder is cross layout, but it is too too fat to move that its layout is made single cylinder engine, and it is that two cylinders link by double-round slide, cause a cylinder to tilt easily, lubricant oil is scurried into piston head easily.Mention a kind of single smooth block stroke piston combustion engine among the utility application specification CN85200337U in 1985, adopt one-piece piston, cancelled connecting rod, it has done a gear pair of 2: 1, complex structure in order to overcome the motion dead point of going up lower dead center on crankshaft and piston, and in high-speed motion, gear pair is easy to generate noise, under impulsive load, also easily owing to deviation causes broken teeth.Mention a kind of double-round slide reciprocating piston internal combustion engine in the Chinese invention patent ublic specification of application 95111403.4 in 1997, on its structure on the no connecting rod type internal combustion engine basis of Japanese industry university in 1981, adopt 90 ° of structures of twin-tub, cylinder head is not adorned in use even a cylinder list is done slideway, still structure is too fat to move but as the single cylinder engine use, and its piston also is an one-piece piston, cancelled connecting rod, its piston is huge and grow, can't make piston bucket face with tratitional technology, piston and cylinder wall are difficult for forming effective oil film; Because it is non-intersect when cylinder axis and crank pin center are most of, cylinder-firing pressure and crank pin reaction force can produce a tilting moment on piston, piston one side upper end and opposite side lower end and cylinder wall touches balance again, though it is very little to compare conventional engines power, but the destruction oil film equally easily that continues to move up and down of single-point contact, piston keeps tilting simultaneously, also leaks gas easily and lubricating oil carry-over; Simultaneously because the consideration of intensity and technology, the volume of its one-piece piston is too fat to move, be difficult to reduce quality, past contact will make cylinder iron and come proof strength as material, though can come balance inertial force by the synthetic method that increases balancer weight then of two cylinder reciprocating forces, the dislocation of two cylinders, also there is a moment of ignoring when calculating, piston is heavy more, and this moment is big more, also causes the quality of entire engine to increase many simultaneously; Its one-piece piston also makes to be torn machine examination open and repaiies very trouble, change piston, just must unpack and tear open greatly; The stroke of motor has been subjected to the restriction of cylinder diameter when designing simultaneously.
