Description
Technical field
The utility model belongs to the hydraulics field, relates to the lubricating oil path of the lubricating oil path of motor, particularly a kind of motor car engine.
Background technique
Along with constantly aggravation of automobile product competition, cause automobile enterprise that the exploitation of new model is constantly accelerated.Though the quality of automobile part is subjected to the profile of its car body, the influences such as auxiliary facility in the car, the performance of automobile is the central factor of this automobile quality of decision all the time.Motor directly determines the rideability of automobile as the core drive unit of automobile.Briefly, a good car must have a high-quality motor.
Motor is made up of two great institutions and five big systems, promptly is made up of connecting rod, distribution device, fuel supply system, lubricating system, cooling system, igniting system and starting system.
The major function of the lubricating system of motor is: 1. make machine oil form continuous oil film at all friction surfaces of moving parts, to reduce the friction between the part, finish lubricated; 2. make machine oil in cyclic process, flow through the part time job surface, finish the cooling of part; 3. make machine oil can take away the broken end of metal that friction surface produces and be deposited on carbon distribution on cylinder, piston, piston ring and other component, play cleaning action; 4. attached to the oil film on cylinder wall, piston and the piston ring, can play seal action; 5. antirust.
The lubricating oil path component of existing motor are numerous, comprise fuel filter, oil pump, filter cleaner, main oil gallery, branch oil duct, cylinder cap oil duct, crankshaft main journal, piston cooling nozzle and chain nozzle etc.These component distribution have not only caused whole motor volume huge, and have made its inner complex structure inside and outside the cylinder of motor, the processing charges height, and the cycle of processing is long.If lubricating oil path that can be right redesigns, reduce the component of some oil circuits, the cost of production of motor is reduced much, what is more important can allow the build of motor diminish, and the competitive ability of the motor of small body type is big more more under equal horsepower.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at existing technology, and a kind of simple in structure, lubricating oil path that can reduce the motor car engine of component is provided.
The purpose of this utility model can realize by following technical proposal: a kind of lubricating oil path of motor car engine, the fuel filter and the oil pump that comprise the cylinder outside that is arranged on motor, described lubricant oil is flowed through fuel filter, oil pump, filter cleaner successively to main oil gallery, flow to cylinder cap oil duct, crankshaft main journal, piston cooling nozzle and chain nozzle respectively from main oil gallery again, it is characterized in that the pump housing of described chain nozzle and oil pump is an integral structure.
The main effect of this lubricating oil path is that each parts to engine interior are lubricated and cool off.It is simple more that lubricating oil path is arranged, the internal structure of motor is just simple more, also just easy more production.Timing chain mainly connects camshaft and bent axle, making bent axle drive camshaft rotates, lubricant oil from the chain nozzle ejection to timing chain, this timing chain is lubricated, after directly being made in the chain nozzle on the pump housing, not only reduced the part of lubricating oil path, made the internal structure of motor simple; And in processing, just guaranteeing the validity of chain nozzle and pump housing position, the bigger error of generation makes the chain nozzle can lubricate timing chain accurately when preventing to assemble in the later stage.
In the lubricating oil path of above-mentioned motor car engine, described chain nozzle is integrated on the pump housing of oil pump by forging type.The pump housing of oil pump is generally by forging type machine shaping, and the cost of casting is also relatively more cheap, can make firm the combining of the chain nozzle and the pump housing.
In the lubricating oil path of above-mentioned motor car engine, described cylinder cap oil duct comprises cylinder cap inner chamber and camshaft inner chamber, described cylinder cap inner chamber is connected by return tube with fuel filter, the axle journal place of described camshaft offers the oil outlet that communicates with the camshaft inner chamber, described camshaft inner chamber also communicates with the oil inlet pipe that is arranged on the camshaft-bearing cap place, the other end and the main oil gallery of described oil inlet pipe communicate, and lubricant oil is flowed through oil inlet pipe, camshaft inner chamber, oil outlet, cylinder cap inner chamber, return tube successively to fuel filter.
The distribution device of motor comprises camshaft and timing chain, is used to control the switching of the valve of cylinder.When camshaft rotates, need be lubricated and cool off, its operating life is prolonged it.Lubricant oil enters from the oil inlet pipe of the bearing cap of camshaft, the inner chamber that passes camshaft flows out from oil outlet again, so not only there is lubricant oil on the camshaft all the time, and, camshaft is remained in the predetermined temperature province along with flowing of lubricant oil can constantly be taken away heat in the camshaft.The lubricant oil that comes out from the camshaft inner chamber converges in the cylinder cap inner chamber, can cool off the cylinder cap inner chamber.The cylinder cap oil duct utilizes the structure of each component inside to be used as the oil duct of lubricant oil cleverly, not only makes overall structure compact more, and has saved the special oil pipe of part, has reduced cost.
Compared with prior art, the lubricating oil path of this motor car engine has reduced the part of lubricating oil path, makes the internal structure of motor simple; Overall structure is compact more, and has saved the special oil pipe of part, has reduced cost.
