Abstract

A connecting rod used for an engine crankshaft comprises a connecting rod main body. A big-head hole and a small-head hole are separately formed in the two ends of the connecting rod main body. The big-head hole is connected with a connecting-rod shaft neck of the crankshaft and is composed of an upper half circular groove and a lower half circular groove, wherein a combination plane between the upper half circular groove and the lower half circular groove is parallel to the cross section where the axis of the connecting rod is located, two lower connecting parts each provided with an upward protruding step are separately formed on the left side and the right side of the lower half circular groove, two upper connecting parts matched with the lower connecting parts are separately formed onthe left side and the right side of the upper half circular groove, and the upper connecting parts are detachably connected with the lower connecting parts. According to the connecting rod, the stressposition of a traditional pull rod is changed, and the stress is applied to the protruding steps of the connecting rods when the crankshaft rotates, so that damage to a fastening screw is prevented,and the service life of the connecting rod is greatly improved.

Description

technical field [0001] The invention relates to the technical field of engines, and more specifically refers to a connecting rod used on an engine crankshaft. Background technique [0002] The crank connecting rod mechanism is the mechanism by which the engine generates and transmits power, through which the linear reciprocating motion of the piston is converted into the rotational motion of the crankshaft to output power. It includes pistons, piston pins, connecting rods, crankshafts and cylinder blocks, etc. [0003] refer to figure 1 At present, the existing connecting rod includes a connecting rod main body 1, and the two ends of the connecting rod main body 1 are respectively provided with a large end hole 10 and a small end hole 20, wherein the large end hole 10 is connected with the connecting rod journal of the crankshaft. Big head hole 10 is made up of left semicircular groove body 11 and right semicircular groove body 12, two left connecting parts 111 are respect...
