Abstract
The utility model relates to an automobile part, and in particular relates to an automobile-engine connecting rod. The automobile-engine connecting rod comprises a connecting rod large head, a connecting rod body and a connecting rod small head, and is characterized in that a through oil hole is processed on the connecting rod body along the axial center; one end of the oil hole is arranged at the connecting position between the connecting rod large head and a crankshaft, and the other end of the oil hole is arranged at the top end of the outer wall of the connecting rod small head; the oil hole is used for lubrication of the connecting positions between the connecting rod large head and the crankshaft and between the connecting rod small head and a piston. The automobile-engine connecting rod has the advantages of reasonable position of oil hole structure, good lubrication, flexibility in operation and long service life.
Description
Technical field
The utility model relates to a kind of automobile component, a kind of specifically connection rod of automobile engine.
Background technique
We know; Connection rod of automobile engine is one of key component of motor car engine; The effect of engine link is that the power that piston bears is passed to bent axle; And the to-and-fro motion that makes piston changes rotatablely moving of bent axle into, and its structure of the engine link that uses on the market is made up of parts such as connecting rod shank, connecting rod cap, connecting-rod bolts and connecting rod bearing shells.Engine link require running must be stable, flexibly, the life-span is long; So the project organization of connecting rod oilhole is very important; The oilhole project organization of present many connection rod of automobile engine is unreasonable; Its shortcoming is often to cause connecting rod and bent axle, piston joint insufficient lubrication, and the work that runs improperly influences working life.
Summary of the invention
The purpose of the utility model is the deficiency to existing technology, provides a kind of oilhole locations of structures reasonable, and is lubricated good, goes slick the connection rod of automobile engine of long service life.
The purpose of the utility model is to realize like this; This connection rod of automobile engine comprises connnecting rod big end, connecting rod shank, connecting rod small end; It is characterized in that: axial centre is processed with the oilhole of a perforation in said connecting rod shank upper edge; One end of described oilhole connnecting rod big end with the bent axle joint, the other end of oilhole is on the outer wall top of connecting rod small end, oilhole is used for the lubricated of connnecting rod big end and bent axle, connecting rod small end and piston joint.
The utlity model has following advantage and good effect:
1, the connecting rod shank of the utility model adopts I-shape beam to add the circular arc design, and the oilhole of a perforation of processing can guarantee that connecting rod and bent axle, piston joint are lubricated good, and running is flexibly stable, the working life of raising connecting rod.
2, the utility model reasonable in design has satisfied the connecting rod required lubricating requirement that in motor, turns round well.
Description of drawings
Fig. 1 is a connection rod of automobile engine overall structure schematic representation.
Fig. 2 is the utility model shaft position A-A sectional drawing.
Embodiment
As shown in Figure 1: this connection rod of automobile engine comprises connnecting rod big end 1, connecting rod shank 2, connecting rod small end 3; It is characterized in that: the oilhole 4 that is processed with a perforation in said connecting rod shank 2 upper edge axial centre; One end of described oilhole 4 connnecting rod big end 1 with the bent axle joint; The other end of oilhole 4 is on the outer wall top of connecting rod small end 3, and oilhole 4 is used for connnecting rod big end 1 and lubricates with the piston joint with bent axle, connecting rod small end 3.
During use, connecting rod small end 3 is connected piston, connnecting rod big end 1 links to each other with the rod journal of bent axle.Shaft 2 is " H " shape section, and the oilhole 4 that runs through on the shaft 2 plays good lubrication for connnecting rod big end 1 and bent axle, connecting rod small end 3 with the piston joint.
