Abstract
The utility model relates to a connecting rod of 2.2-liter TCI gasoline engine, which comprises a big end, a small end and a body of the connecting rod, the small end of connecting rod is connected with a piston pin fixedly, the centre distance between the holes in the big end and small end is 150 mm, the thickness of the rod body is 13.2 mm. The bore diameter in the big end of connecting rod is 48 mm, and the bore diameter in the small end of connecting rod is 23 mm. The space between the threaded holes of connecting rod is 58 mm. The utility model can meet the performance requirements for the engine of high power, low fuel consumption, and low vibration etc, and can be applied to the high power gasoline engine for high-speed light weight motor vehicle.
Description
Technical field
The utility model relates to a kind of engine components, is specifically related to the petrolic connecting rod of a kind of TCI.
Background technique
Connecting rod is one of strength member of motor, and it is very abominable in the working condition of engine interior.Connecting rod passes to bent axle with the piston pressure that is born, and compressive stress is very high.It is also with piston component movement parts, so the balance of inertial mass has a significant impact the durability in the stationarity of engine running, high rotating speed district.The engine performance of high power, low fuel oil consumption, low vibration etc. all requires to alleviate connecting rod weight in recent years, but present applied connecting rod still can not well satisfy this requirement.
The model utility content
The utility model has been designed the connecting rod of lighting at the deficiencies in the prior art, to satisfy the requirement of engine performance such as high power, low fuel oil consumption, low vibration.
The utility model is achieved through the following technical solutions:
A kind of 2.2 liters of petrolic connecting rods of TCI comprise connnecting rod big end, connecting rod small end and shaft, and connecting rod small end is fixedlyed connected with wrist pin, and CONCENTRIC REDUCER hole centre distance is 148mm～152mm, and shaft is thick to be 12mm～15mm.
2.2 rise the petrolic connecting rod of TCI, CONCENTRIC REDUCER hole centre distance is 150mm, shaft is thick to be 13.2mm.
2.2 rise the petrolic connecting rod of TCI, the connnecting rod big end aperture is φ 46mm～φ 50mm, the connecting rod small end aperture is φ 20mm～φ 24mm.
2.2 rise the petrolic connecting rod of TCI, the connnecting rod big end aperture is φ 48mm, the connecting rod small end aperture is φ 23mm.
2.2 rise the petrolic connecting rod of TCI, the spacing between the connecting rod tapped hole is 58mm.
The beneficial effects of the utility model are: the design of size is alleviated the weight of connecting rod under the requirement of satisfying intensity.Because connecting rod small end fixedlys connected with wrist pin, make and do not press lining in the connecting rod small end, further reduce connecting rod quality.Connecting-rod bolts adopt the minor diameter high-strength bolt, and improve screwing force by the plastic zone method of tightening, and guarantee the bigger power of motor output.The utility model can satisfy the requirement of the engine performance of high power, low fuel oil consumption, low vibration etc., can be applicable on the high-power petrol engine of high-speed light-duty vehicle.
