Description
Technical field
The present invention relates to motor car engine, more specifically to the lubricating oil path of automobile engine cylinder-body assembly.
Background technique
Usually the oil sump of motor is in the majority with stamping part, because of stamping part belongs to thin-wall part, stamping process can not guarantee at the inner lubricating oil path that forms complexity of oil sump simultaneously, therefore engine sump tank inside does not have the layout design of lubricating oil path in the past; the shortcoming of the oil sump of thin-walled punching press is that noise is big after the final assembly, the distortion of easily colliding with; Mostly the main bearing cap of motor was the several separate structural design in the past, and promptly four cylinder engine has 5 independently main bearing cap, and the shortcoming of independent main bearing cap is that the main bearing cap integral rigidity is poor, and total noise of centrifuge and cylinder hole static deformation are all had adverse effect.Therefore the form that the motor that has the people to design adopts one-piece rotor shaft to hold lid, it promptly is frame structure, but its design unlubricated oil circuit in framework, oil pump is to realize by outer connecting leg road with being connected of main oil gallery, and basic oil circuit moves towards as follows: oil trap assembly → engine oil pump assembly → outer connecting leg road → oil filter → cylinder body auxiliary oil channel → main oil gallery → oblique oil duct and the upright oil duct of cylinder cap.Reason owing to outer connecting leg road, this design seems in disorder, increased the risk of the damage of colliding with simultaneously, the damage of colliding with easily causes leakage of oil or seepage, cause oil circuit to damage, motor can not be worked, and causes the lubricant oil pressure release can not guarantee the lubricated of motor, and the structural design on outer connecting leg road is attractive in appearance inadequately simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of minimizing damage of colliding with, and avoids the lubricating oil path of the engine cylinder assembly that oil circuit damages.
The present invention includes oil trap, oil pump, oil filter, cylinder body, cylinder cap, oil sump, be provided with the upright oil duct of main oil gallery, the auxiliary oil channel that is connected with oil filter, oblique oil duct and grease cylinders cap assembly movement parts in the cylinder body, it is characterized in that: also comprise framework, be provided with oil duct in oil sump, frame mechanism, basic oil circuit moves towards as follows: oil trap → oil pump → oil sump duct → framework oil duct → cylinder body auxiliary oil channel → oil filter → oblique oil duct of cylinder body main oil gallery → cylinder body and cylinder cap found oil duct.So-called framework just is meant that one-piece rotor shaft holds lid, the main bearing cap of most of motor all was independently in the past, as four-cylinder 5 independently main bearing cap are arranged, this motor connects main bearing cap independently for whole, be called framework, the plane is connected with the cylinder body bottom surface by 10 bolts on the framework, the framework bottom surface connects oil sump, frame supported motion assemblies such as bent axle and piston rod, formed the support frame of motor jointly with cylinder body, main bearing cap integral frame structure is compared with main bearing cap independently and has been strengthened rigidity of cylinder, has reduced the vibration noise of motor, reduced the static deformation amount of cylinder body simultaneously, certain benefit has been arranged reducing oil consumption.
The oil duct of above-mentioned oil sump is to be connected to form by plurality of sections, the section with section between be vertical the connection.Vertical connection can make things convenient for oil circuit to move towards to arrange and processes, and vertical connection is beneficial to the smooth and easy circulation of processing and lubricant oil.
The oil duct of above-mentioned oil sump is four sections.Be divided into four sections and be convenient to oil duct two ends link position and processes.
Above-mentioned cylinder body design has a technology oil duct, and the technology oil duct is communicated with main oil gallery and leads to the upright oil duct of cylinder cap.The technology oil duct is a kind of transition oil duct, is in order to realize main oil gallery and the connection of leading to the upright oil duct of cylinder cap.
Above-mentioned oil sump blank is a cast member.It is the total noise of centrifuge that has reduced motor that the oil sump blank adopts the benefit of casting technique moulding, makes the complicated lubricating oil path of portion's design within it that guarantee has been arranged simultaneously.
Framework of the present invention and oil sump indoor design lubricating oil path, cylinder body effectively is connected with the lubricating oil path of oil pump with oil sump and oil sump with framework, framework, form a succinct lubricating oil path smoothly, for movement parts in the cylinder assembly lubricated provides reliable assurance.If in framework He in the oil sump, can not construct lubricating oil path, for the unobstructed design external pipeline that just needs that guarantees whole lubricating oil path oil pump oil circuit and cylinder body oil circuit are coupled together like this.Therefore the present invention can avoid the damage of colliding with owing to do not need external lubricating pipe, and oil circuit damages, the lubricant oil pressure release, and structural design is attractive in appearance simultaneously.The advantage that the present invention designs the integral frame structure is the integral rigidity that has strengthened engine cylinder-body, has reduced the static deformation amount in vibration noise and cylinder hole, to reducing engine oil consumption certain benefit is arranged.

In the accompanying drawing: 1, oil trap assembly, 2, engine oil pump assembly, 4, oil filter, 5, the cylinder body auxiliary oil channel, 6, main oil gallery 7, oblique oil duct, 8, the upright oil duct of cylinder cap, 9, the technology oil duct, 10, oil sump duct, 11, the framework oil duct
The invention will be further described below in conjunction with the drawings and specific embodiments.
Embodiment
The oil sump of available engine mostly is the sheet metal stamping part greatly, and this technology can not be implemented in oil sump indoor design lubricating oil path, and because of belonging to thin-wall part, vibrating noise is bigger.The lubricating oil path of available engine moves towards as follows: oil trap assembly → engine oil pump assembly → outer connecting leg road → oil filter → cylinder body auxiliary oil channel → main oil gallery → oblique oil duct and the upright oil duct of cylinder cap.
The effect of oil trap assembly is to draw machine oil in oil sump, and carries out primary filter.The effect of engine oil pump assembly is to draw machine oil and for machine oil pressurizes, in have oil circuit to be connected with outer connecting leg road with oil trap.The effect on outer connecting leg road is to realize that the machine oil that engine oil pump assembly comes out enters in the oil filter, and the effect of oil filter is that machine oil is filtered, and the machine oil after the filtration enters main oil gallery by the cylinder body auxiliary oil channel.The effect of main oil gallery is to provide the machine oil with certain pressure for each kinematic pair in the cylinder body.Tiltedly oil duct directly is connected with main oil gallery with the upright oil duct of cylinder cap, so that realize lubricating kinematic pair in crankshaft link rod motion pair and the cylinder cap.
