Abstract
The utility model discloses a swing three-section linkage rod apparatus for an internal combustion engine, which is mainly composed of a small linkage rod, a swing linkage rod and a large linkage rod, wherein, one end of the small linkage rod is movably connected with a piston, and the other end is movably connected with one end of the swing linkage rod; the other end of the swing linkage rod is movably connected with a pin shaft on a machine body of the internal combustion engine; one end of the large linkage rod is movably connected with a crank shaft, and the other end is also movably connected with the swing linkage rod. The utility model has the advantages that the motion track of the piston can be changed; fuel can combust sufficiently during the compression-combustion process; the exhaust of harmful gas is obviously reduced; the output of work force can be increased. The utility model is mainly applied to the internal combustion engine.
Description
The utility model relates to a kind of connecting rod means, relates in particular in the internal-combustion engine and to-and-fro motion to be converted to the swing three joint connecting rod meanss that rotatablely move.
In modern economy, automobile and tractor has become the pillar industry of developing the economy, internal-combustion engine is the important component part of automobile and tractor, and crank connecting rod apparatus is an indispensable part in the internal-combustion engine, it is the device that transmits the piston work done, can convert the to-and-fro motion of piston to bent axle rotatablely move.Normally used internal-combustion engines crank-connecting rod device is made up of bent axle and single connecting rod, use such crank connecting rod apparatus that there is certain resistance in the transmission of the effective merit of internal-combustion engine, therefore, have following shortcoming: 1, piston is short in the time of top dead center position, cause the fuel combustion time short, fuel combustion is insufficient, thereby gives off harmful gas, befouling environment; 2, connecting rod is at piston arrives atdc 10 degree to the maximum thrust of bent axle in the single crank connecting rod apparatus, the crank throw of piston, single connecting rod and bent axle just in time in a straight line at this moment, bent axle does not have brachium, will consume the power of piston, make piston very short to the actuating length and the time of bent axle, the power utilization ratio is also low, also can increase wearing for piston simultaneously.
The purpose of this utility model is the swing three joint connecting rod meanss of a kind of internal-combustion engine of design, and it can prolong the fuel combustion time, makes full combustion of fuel, reduces discharge of harmful gases, and can change the movement locus of piston, improves the power output of internal-combustion engine.
For achieving the above object, the technical solution of the utility model is, the swing three joint connecting rod meanss of a kind of internal-combustion engine, comprise crankshaft-and-connecting-rod, it is characterized in that: described connecting rod by small rod, wave connecting rod and big connecting rod three joint connecting rods and form, one end of small rod and the piston in the cylinder flexibly connect, the other end is connected and waves on the connecting rod, an end that waves connecting rod is movably connected on the bearing pin on the internal combustion (IC) engine airframe, one end of big connecting rod is movably connected on the bent axle, and the other end also is movably connected in and waves on the connecting rod.
The utility model has the advantages that: 1, prolonged the period of combustion of fuel in combustion process, fuel can fully burn, and reduces discharge of harmful gases; 2, swing crank connecting rod apparatus has changed the movement locus of piston, has improved the power output of internal-combustion engine.
Below in conjunction with accompanying drawing the utility model is described in further detail.
As seen from the figure, the utility model connecting rod means by small rod 3, wave connecting rod 6 and big connecting rod 8 three joint connecting rods and form.One piston 2 is arranged in cylinder 1, piston 2 can move back and forth in cylinder 1, one end of small rod 3 is movably connected on the piston 1, an end that waves connecting rod 6 is installed on the bearing pin 9 on the frame 7, in the other end of waving connecting rod 6 bearing pin 4 and 5 is installed, bearing pin 4 and 5 is along with the swing of waving connecting rod 6 is also done circular motion around bearing pin 9, the other end of small rod 3 just is connected on the bearing pin 4, one end of big connecting rod 8 is connected on the bearing pin 5, the other end is movably connected on the bent axle 10, small rod 3 and big connecting rod 8 with wave the end that connecting rod 6 is connected and both can rotate around bearing pin 4 and 5, also all the time along with circular motion is done in the swing of waving connecting rod 6.
In the working procedure of any internal-combustion engine, the compression and combustion process of a fuel-air mixture all to be arranged, thrust maximum when piston is spent in arrival atdc 10.Use this practical swing three joint connecting rod meanss, internal-combustion engine in the course of the work, earlier reciprocating by piston 2, drive small rod 3 motions that connect thereon, drive again and wave connecting rod 6 around bearing pin 9 swings and 8 motions of promotion big connecting rod, promoting bent axle 10 by big connecting rod 8 then rotates, small rod 3 and big connecting rod 8 with wave a end that connecting rod 6 is connected all the time along with the bearing pin 4 and 5 that waves on the connecting rod 6 is done circular motion, pass through the acting in conjunction of three connecting rods like this, piston 2 shifts to an earlier date 10 degree than bent axle 10 and arrives top dead centers, make piston 2 a gradually slow movement process be arranged at top dead center position, in this process, prolonged the period of combustion of fuel oil, and fuel oil energy fully burns; Simultaneously, when piston 2 arrives atdc, piston 2, small rod 3, big connecting rod 8 and bent axle 10 are out-of-line, just produce certain brachium, this brachium can produce thrust to bent axle 10, increases brachium and has just increased arm strength, has just increased the thrust to bent axle 10, also just increase the distance of bent axle 10 corners, increased the output of power.The experiment proved that, use the swing three joint connecting rod meanss of the utility model, can change the movement locus of piston, fuel oil can fully be burnt in the compression and combustion process, obviously reduce discharge of harmful gases, and can increase the output of power.
The utility model mainly is applicable to internal-combustion engine.
