Abstract
The utility model relates to a car part and specifically relates to a car engine connecting rod with a wedge-shaped structure. The car engine connecting rod comprises a great connecting rod end, a connecting rod body and a small connecting rod end; the car engine connecting rod is characterized in that the tail end of the small connecting rod end is forged and formed by one step; the small connecting rod end adopts a wedge-shaped structural form, the height H of the thick wedge-shaped end is 20.8mm, the height M of the thin wedge-shaped end is 12 mm, transitional circular-arc radius R of a counter bore edge is 21mm, the width N of the thick wedge-shaped end is 9.2 mm, the width P of the thin wedge-shaped end is 13.32mm, and dimension difference Q between the thick wedge-shaped end and the thin wedge-shaped end is 4.52mm.The car engine connecting rod with the wedge-shaped structure is reasonable in structure, and has characteristics of being light in weight and high in strength; the tail end of the small connecting rod end is forged and formed by one step, so that unnecessary machining flow is eliminated, and time and cost are lowered.
Description
Technical field
The utility model relates to a kind of automobile component, specifically a kind of wedge-shaped structure 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 is born is passed to bent axle, and the to-and-fro motion that makes piston changes rotatablely moving of bent axle into, its structure of the engine link using on market is made up of parts such as connecting rod shank, connecting rod cap, connecting-rod bolts and connecting rod bearing shells.The design direction of connection rod of automobile engine is lightweight, intensity is large, the structural design majority of connection rod of automobile engine is laid particular stress at present, being difficult to both takes into account, microcephaly's amount of finish of existing general-utility car engine link blank is large, cause very burden to following process, affect manufacturing efficiency simultaneously, increase cost.
Existing structure engine link connecting rod small end upper surface parallel with lower surface (shown in Fig. 4), does not have the drop of size, and finished product adds the special cutter of man-hour requirement, and amount of finish is large, and cost significantly improves.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of wedge-shaped structure connection rod of automobile engine is provided, this engine connecting rod structure rationally, have lightweight, the large feature of intensity, forging molding of connecting rod small end end concurrently, save unnecessary machine and add flow process, save time and cost.
The purpose of this utility model is to realize like this, this connection rod of automobile engine comprises connnecting rod big end, connecting rod shank and connecting rod small end, it is characterized in that: described forging molding of connecting rod small end end, described connecting rod small end adopts wedge-shaped structure form, the thick end height H of its wedge shape is 20.8mm, the height M of the thin end of wedge shape is 12mm, the transition arc radius R at counterbore edge is 21mm, the width N of the thick end of wedge shape is 9.2mm, the width P of the thin end of wedge shape is 13.32mm, and the drop size Q of the thick end of wedge shape and thin end is 4.52mm.
The utlity model has following advantage and good effect:
1, connnecting rod big end of the present utility model is simple for structure, microcephaly adopts wedge-shaped design, alleviated connecting rod own wt, and the design of the I-shape beam shape of shaft strengthens intensity and the force balance of connecting rod, therefore under the requirement of Strenth and stress that ensures connecting rod, alleviated the weight of connecting rod.
2, the utility model, in order further to reduce amount of finish, adopts wedge shape arc transition structural design by connecting rod small end, and said structure is greatly improved the economic benefit of processing producer.
3, the utility model rational in infrastructure, have lightweight, the large feature of intensity, forging molding of connecting rod small end end concurrently, save unnecessary machine and add flow process, save time and cost, adapt to connecting rod and engine design direction.
