Abstract
The utility model relates to the oil pump of a 2.2 L pressurization inter cooling petrol engine, consisting of a machine body, a machine oil pump body, an oil pump shell, an oil filter, an oil filter support saddle, an oil pump cover, an machine sealing gasket and the drive and driven gear of the oil pump. The oil pump body is installed on the front head face of the machine. The oil filter support saddle and the oil pump cover are installed on the oil pump shell and form an enclosed oil path together with the machine and the machine sealing gasket. The utility model has the advantages of compact structure, small occupied land and small weight.
Description
Technical field
The utility model relates to technical field of internal combustion engines, relates to the petrolic oil pump of a kind of charge inter cooling specifically.
Background technique
Oil pump is one of most important parts of engine lubrication system, its effect is the circulation of setting up engine oil pressure and guaranteeing lubricating oil, specifically be that the machine oil in the oil sump oil sump is sucked, forming vacuum by the main driven gear engagement to make machine oil to arrive each working surface of motor by pipeline to the machine oil pressurization.Oil pump is the heart of engine lubrication system, is by crank-driven gear or rotor rotation, forms vacuum and set up engine oil pressure in oil pocket.This just requires the sealing of pump chamber very high, the sealing that can continue under enough pressure.But the sealing of the assurance pump chamber that present oil pump can not continue under bigger pressure.If structurally effectively guarantee sealing can make pump housing volume bigger again, total quality is also bigger.Thereby influence every performance of car load.
The model utility content
The utility model is at the deficiencies in the prior art, designed and developed out reliable operation, simple in structure, drive power losses is minimum, long working life, in the hope of under the prerequisite that guarantees sealing and performance requirement, saving the space, reduce the petrol engine oil pump of quality.
The utility model is achieved through the following technical solutions:
2.2L the petrolic oil pump of charge inter cooling, include the main driven gear of body, the oil pump pump housing, oil pump housing, oil filter, oil filter bearing, oil pump cover, body gasket seal and oil pump, the described oil pump pump housing is installed on the body front-end face; Described oil filter bearing and oil pump cover are installed on the oil pump housing and body and body gasket seal form the sealing oil circuit together.
2.2L the petrolic oil pump of charge inter cooling, described oil pump housing is connected on the body front-end face with hexagon flange bolt.
2.2L the petrolic oil pump of charge inter cooling, described oil pump main driven gear centre distance is 30mm～40mm.
2.2L the petrolic oil pump of charge inter cooling, described oil pump main driven gear centre distance is 36mm.
2.2L the petrolic oil pump of charge inter cooling, described oil pump driving gear are the right hand helix gear, oil pump driven gear is left-handed spiral gear.
Its form of the utility model oil pump is a gear type oil pump, and driving moment is from motor left side trunnion shaft, reliable operation, simple in structure, drive power losses is minimum, long working life; Adopt the integral high pressure cast structure, hexagon flange bolt with the different length of 9 M8-6g is installed on the body front-end face, the best centre distance of main driven gear is 36mm, oil filter bearing and oil pump cover are installed on the oil pump housing, form the sealing oil circuit together with body and body gasket seal, compact structure, thus under the prerequisite that guarantees sealing and performance requirement, save the space, reduce quality.
Description of drawings
