Description
Technical field
The utility model is related to a kind of drive systems, are the drives of a kind of high-pressure oil pump of engine and lubricating oil pump specifically
Dynamic system.
Background technology
Modern Engine structure is more and more compacter, and institute's band peripheral accessory is also more and more, such as lubricating oil pump, high-pressure oil pump, height
Warm water pump, starts motor etc. at low temperature water pump, engine gear system is undoubtedly made to become increasingly complex, design aspect considers just first
It is space requirement, also manufactures cost, mounting process etc., all restrict the development of Modern Engine compact.
Invention content
The technical problems to be solved in the utility model is：The driving system of a kind of high-pressure oil pump of engine and lubricating oil pump is provided
System simplifies engine free end tooth train, saves installation space, reduces cost.
The drive system of a kind of high-pressure oil pump of engine and lubricating oil pump, including engine free end tooth train and oil pump group
It closes, engine free end tooth train includes master gear, intermediate idler and oil pump gear, and master gear passes through intermediate idler driving machine
Oil pump gear；Oil pump combination includes the lubricating oil pump being axially distributed along engine shaft and high-pressure oil pump, high pressure oil pump shaft pass through axle sleeve
Together with lubricating oil pump axis connection.
The quantity of the drive system of high-pressure oil pump of engine described in the utility model and lubricating oil pump, lubricating oil pump and high-pressure oil pump
It is 2, is respectively distributed to the arranged on left and right sides of engine free end lower part.
The drive system of high-pressure oil pump of engine described in the utility model and lubricating oil pump, engine free end tooth train are also wrapped
Water pump gear and output gear are included, master gear drives water pump gear and output gear by intermediate idler.
The beneficial effects of the utility model：The utility model is high using the coaxial type of drive of high-pressure oil pump and lubricating oil pump
For pressure oil pump shaft together with lubricating oil pump axis connection, master gear drives oil pump gear, oil pump gear driving by intermediate idler
Machine oil pump shaft works normally lubricating oil pump, and machine oil pump shaft drives high-pressure oil pump shaft rotation to move by axle sleeve, makes the normal work of high-pressure oil pump
Make.After Driven by Coaxial, high-pressure oil pump gear and intermediate idler are saved, simplifies free end gear train, has saved installation
Control reduces cost, and simple in structure, convenient for disassembly and assembly.

Specific embodiment
The utility model is described further in the following with reference to the drawings and specific embodiments.
The drive system of a kind of high-pressure oil pump of engine and lubricating oil pump, including engine free end tooth train and oil pump group
Close, as shown in Figure 1, engine free end tooth train include the oil pump gear 001,2 of master gear 004,2 water pump gear 003,
1 output gear 006 and 3 intermediate idlers（Including 2 intermediate idlers 002 and 1 intermediate idler 005）, master gear 004 passes through
Intermediate idler 002 drives oil pump gear 001 and water pump gear 003, and master gear 004 drives output gear by intermediate idler 005
Wheel 006.
As shown in Fig. 2, oil pump combination includes the lubricating oil pump 2 being axially distributed along engine shaft and high-pressure oil pump 3, machine oil pump shaft
21 are linked together by axle sleeve 22 and high pressure oil pump shaft 31.
In the present embodiment, the quantity of lubricating oil pump 2 and high-pressure oil pump 3 is 2, is respectively distributed to the left side at engine free end
Side and right side.
When the drive system of high-pressure oil pump of engine described in the present embodiment and lubricating oil pump works, master gear 004 passes through centre
Idle pulley 002 drives oil pump gear 001 to rotate, when 001 driving machine oil pump shaft 21 of oil pump gear rotates, 2 normal work of lubricating oil pump
Make；Since machine oil pump shaft 21 is linked together by axle sleeve 22 and high pressure oil pump shaft 31, so machine oil pump shaft 21 passes through axle sleeve 22
Driving high pressure oil pump shaft 31 operates so that high-pressure oil pump 3 works normally.
