Abstract
The invention discloses a fuel pump system integrated with an engine body. The structure is that an engine body recessed cavity of a fuel pump is arranged on the engine body, and a casing recessed cavity identical with the engine body recessed cavity in shape is arranged on a fuel pump casing. A driving shaft and a driven shaft are respectively arranged on boss shaft sleeves in the recessed cavities, and a driving gear and a driven gear are respectively embedded in the driving shaft and the driven shaft. The driving shaft with the driving gear penetrates through the boss shaft sleeve of the fuel pump casing to be connected with a fuel pump gear outside the fuel pump casing. The fuel pump casing and the engine body recessed cavities are fastened and sealed through bolts and rubber rings to form a complete fuel pump working cavity. A large portion of the fuel pump working pump occupies space in the engine body to enable structure outside the fuel pump to be very small. When identical pressure and flow in a main oil channel are achieved, overall dimension of the engine is remarkably reduced. Therefore, the matching difficulty of the engine and a whole vehicle can be reduced, and large maintenance space is retained for the whole vehicle. The structure can be widely applied to any engine due to the fact that the system is simple and compact in structure.
Description
Technical field
The invention belongs to engine components, be specifically related to a kind of oil pump system and device that is integrated with body.
Background technique
The main task of the lubrication system of motor is machine oil to be delivered to the surface of each motion component, makes friction pair be in lubricating status, when reducing wear, takes away the heat that produces owing to friction.DENG adopts the power source of oil pump as engine oil pressure in the lubrication system and flow.The engine oil pump assembly of general motor is that the pump housing and fuel filter are connected as a single entity, and is directly installed in the engine sump tank.This set structure needs the oil sump of motor must have enough capacity and volume to be used for the loader oil pump, require its oil sump size bigger, so the volume of motor to be also bigger thereupon.Very unfavorable when the oil sump of larger volume matees car load, especially design and the coupling to the component such as vehicle frame, crossbeam and drag link below the motor causes difficulty.The present invention will propose a kind of simple in structure, compact engine oil pump device, with the fuel filter of the pump housing and small volume be arranged in the body with oil sump in, the oil sump volume of motor is reduced, the layout of motor peripheral components is compact and reasonable more.
Summary of the invention
The objective of the invention is, design and a kind ofly be embedded in the engine body, form the oil pump body of pressure chamber jointly, make motor machine overall structure compact more with body.
Below in conjunction with accompanying drawing structural principle of the present invention is described.Oil pump system with engine body is integrated comprises engine body, driving shaft, driven shaft, driving gear, driven gear, oil pump case, oil pump gear, cushion rubber, fuel filter and oil sump etc.Engine body is provided with the body cavity of oil pump, in cavity, is respectively equipped with driving shaft and driven shaft on the axle sleeve of body boss, and driving shaft and driven shaft stud with driving gear and driven gear separately respectively.The right side inwall of body cavity is provided with filler opening, and filler opening communicates with the oil duct of organism bottom; The left side of oil pump body cavity is provided with the oil outlet that connects main oil gallery.Oil pump case is provided with the housing cavity identical with the body cavity shapes; The housing cavity also is provided with the housing boss identical with the body cavity shapes and two axle sleeves; The driving shaft that has driving gear passes the axle sleeve of oil pump case boss, and the oil pump gear outside with oil pump case is connected.Oil pump case and body cavity form the complete oil pump active chamber through bolt and cushion rubber fit sealing.
The present invention forms the active chamber of oil pump jointly with the oil pump cavity on housing and the body, and oil pump gear drives coaxial oil pump driving gear and rotates under the drive of engine timing gear; Driving gear drives driven gear and rotates, and in oil suction chamber, forms negative pressure, through the Oil passage that is connected with fuel filter with body; Suck the machine oil in the oil sump by fuel filter; Be delivered to out in the oil pocket, get into the body main oil gallery, reach the lubricated purpose of engine oil pressure.
Characteristics of the present invention and beneficial effect are that the active chamber major part of oil pump takies the space in the body, makes the outside structure of oil pump very little.Reach uniform pressure in the main oil gallery and flow is done the time spent, it is a lot of that the external dimension of motor are obviously reduced, and helps reducing the difficulty of matching of motor and car load like this, leaves the space of bigger maintenance to car load.Because this apparatus structure is simple, compact, so this structure is adapted at extensive use on any motor.
