Explosive connecting rod and engine

Abstract

The invention relates to the field of engines, and discloses a broken connecting rod and an engine. The central axis of the big head of the connecting rod and the central axis of the small head of the connecting rod form a central plane of the connecting rod; Symmetrical beveled surface, along the direction from the small end of the connecting rod to the large end of the connecting rod, the distance from the beveled surface to the central plane of the connecting rod gradually decreases, and the intersection line of the extension surfaces of the two beveled surfaces is located on the central plane of the connecting rod and parallel to the connecting rod. The central axis of the small head of the rod. The oblique section is distributed symmetrically with respect to the central plane of the connecting rod, and the distance from the oblique section to the central plane of the connecting rod gradually decreases along the direction from the small end of the connecting rod to the small end of the connecting rod, which reduces the dimension in the width direction of the connecting rod to meet the engine installation requirements. The space is limited; the weight of the connecting rod is reduced, and the mechanical efficiency is improved; the intersection line of the extension surfaces of the two inclined planes is located on the central plane of the connecting rod and parallel to the central axis of the small end of the connecting rod, and the large end of the connecting rod is stressed Evenly, the force situation of the broken connecting rod is improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to a snap-off connecting rod and an engine. Background technique [0002] The connecting rod is a tool that connects the piston and the crankshaft, transmits the force acting on the piston to the crankshaft, and converts the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod includes a connecting rod body and a connecting rod cover. The connecting rod body includes a connecting rod big end connected to the crankshaft, a connecting rod small end connected to the piston pin, and a connecting rod body connecting the connecting rod big end and the connecting rod small end. , the big end of the connecting rod and the connecting rod cover are connected by bolts to form the big end of the connecting rod. [0003] Connecting rods mainly include flat notch connecting rods and oblique notch connecting rods. Among them, the flat notch connecting rod has ...

AI Technical Summary

Problems solved by technology

However, the dimension of the connecting rod with flat cut is large in the width direction and the weight is large, resulting in a large consumption of mechanical power. Therefore, when the installation space is limited, the connecting rod with oblique cut is used. Due to the large centrifugal force, the bolts connecting the connecting rod cover and the big end of the connecting rod bear a large shear force, and the force of the two bolts is uneven, so the force of the connecting rod with oblique cuts is not good.
