Wherein, described microcephaly is used for being connected with piston 800, and described major part is used for being connected with bent axle 600; Described microcephaly is provided with the first rotation hole mated with described wrist pin; Described major part comprises and the integrated fixing part of described shaft and the active part be removably connected on described fixing part; The cross section of described shaft is " work " font, to increase the intensity of whole connecting rod 700; Described shaft and little head part bend several angle relative to major part, can arrange by full symmetric with the piston 800 and piston cylinder that make to be connected to two connecting rods 700 on same crank throw and above-mentioned two connecting rod 700 correspondences.
The object arranging circular arc is to avoid connecting rod 700 stress concentration, optimizes the mechanical property of connecting rod 700, extends the working life of connecting rod 700.
The structure that this horizontally-opposed distance increasing unit adopts two piston cylinders to be oppositely arranged, the volume of cylinder body can be effectively reduced, shorten the length of bent axle 600, thus reduce difficulty of processing and intensity, the balance that bent axle 600 operates can also be improved simultaneously, thus noise and vibration when effectively reducing internal combustion engine operation, effectively improve the NVH problem of distance increasing unit, make up the defect of prior art.
Finally, it should be noted that, according to the actual requirements, the piston cylinder in the present embodiment also can be 4,6 or 8, and correspondingly, described connecting rod 700 and piston 800 are also 4,6 or 8.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
