Description
Technical field
The utility model relates to engine component technical field, particularly relates to a kind of engine link being convenient to install.
Background technique
The quality of motor, in the judgement of automotive performance, is a very important index.And within the engine, be all need the connecting rod by installing in motor to transmit power.Now bar linkage structure is commercially varied, but the structure of connecting rod self is fairly simple, and engine link is all mainly be bolted to connection by connecting rod shank and connecting rod cap.Simple bolt is fixedly connected with, loosening easily appears in connecting rod shank and the mutual fitting surface of connecting rod cap, fixing insecure, particularly in the dynamically working situation that motor is so powerful, connecting rod does long to-and-fro motion, and the fitting surface of connecting rod shank and connecting rod cap is easy to wearing and tearing, the location caused after wearing and tearing between connecting rod shank and connecting rod cap is inaccurate, thus damaged connecting rod, also damage motor, the safety of automobile self time serious, can have been had influence on.
Model utility content
For the problems referred to above, the utility model provides that a kind of structure is simple, accurate positioning, reliable and stable, be convenient to the engine link installed.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of engine link being convenient to install, comprise connecting rod shank and connecting rod cap, described connecting rod shank and connecting rod cap junction surface are provided with the integrated cylindrical bar with connecting rod shank, the top of described cylindrical bar is provided with thread section, on described connecting rod cap, corresponding circle mast is provided with through hole, and described connecting rod cap is inserted in cylindrical bar by through hole and covers on connecting rod shank, and is connected by supporting fastening nuts.
Further, the connnecting rod big end of described connecting rod shank and connecting rod small end are respectively equipped with nozzle opening and oilhole.
Further, the quantity at least two of described nozzle opening.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
1, the utility model directly one-body molded cylindrical bar on connecting rod shank, does not need other bolt to install, and decreases mechanical processing technique and locating stud press-fits station, easy for installation, improve the reliability of engine link, serviceability and Security, improve manufacturing efficiency, reduce cost.
2, the utility model is respectively equipped with nozzle opening and oilhole on the connnecting rod big end and connecting rod small end of connecting rod shank, and effectively ensure that connecting rod and bent axle, piston joint are lubricated well, running is flexibly stable, improves the working life of connecting rod.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
