Model utility content
The purpose of this utility model is to provide a kind of lubrication system that improves lubricating efficiency, minimizing part development time, reduces the gearbox of component cost.
For solving the problems of the technologies described above, the lubrication system of the utility model gearbox, comprises filter, oil hydraulic pump and the selector valve of connecting successively, and described filter is communicated with lubricating oil sump; Spray bar, one end of described spray bar is communicated with described selector valve, is provided with a plurality of nozzle openings on described spray bar; Between described spray bar and described selector valve, be connected with two paths, a described path is provided with refrigerating module therein; Bearing support, described bearing support is communicated with the other end of described spray bar by low pressure oil duct; Wherein said spray bar and described bearing support are communicated with described lubricating oil sump respectively; And control module, described control module is connected with described selector valve.
Preferably, described spray bar comprises: spray bar body, and described nozzle opening is disposed on described spray bar body; Fixed support, described fixed support is arranged on described spray bar body outside; And O shape circle, described O shape circle is arranged on the filler opening of described spray bar body.
Preferably, the position of described nozzle opening and quantity and gear and synchronizer match.
Preferably, between described oil hydraulic pump and described selector valve, be also connected with a relief valve, the other end of described relief valve is communicated with described lubricating oil sump.
The lubrication system of the utility model gearbox has been used the mode of pressure lubrication, after fluid enters spray bar, on spray bar, have towards the axial several apertures of tooth, under the High Pressure of fluid, parts of lubricating oil, is lubricated dual-clutch transmission gear and the bearing of operating mode complexity by the small hole injection on spray bar to the lubricated gear and synchronizer of needs.Control module is by gathering the rotating speed of TOT Transmission Oil Temperature and gear, control selector valve in lubricating oil path and determine the fluid refrigerating module of whether flowing through, the lubricating efficiency not only improving to a great extent, but also improved wearing and tearing and the sintering character preventing between gear and gear, axle and bearing; By the regulation and control to flow of lubrication and oil circuit, effectively improved the working efficiency of gearbox simultaneously.And spray bar is by the fixed support being welded thereon, and when assembling, only need to, by completing in the respective aperture of the oil outlet of spray bar and fixed support insertion end cap, simplify production technology and assembly technology.

Embodiment
Below in conjunction with accompanying drawing, the lubrication system of the utility model gearbox is described in further detail.
As shown in Figure 1 and Figure 2, the lubrication system of the utility model gearbox, adopt the form of spray bar: the powered lubricating oil that the lubrication system of gearbox provides by means of oil pump circulates in the lubricating loop of gearbox, system front end comprises filter 2, oil hydraulic pump 3 and the selector valve 5 of series connection successively, and filter 2 is communicated with lubricating oil sump 1.Between oil hydraulic pump 3 and selector valve 5, be also connected with a relief valve 4, the other end of relief valve 4 is communicated with described lubricating oil sump 1.System employs servo motor driven oil pump, is integrated with control module in actuating motor.Control module is by gathering the rotating speed of TOT Transmission Oil Temperature and gear, controls selector valve 5 in lubricating oil path and determines the fluid refrigerating module 6 of whether flowing through; Control module, by gathering the load of TOT Transmission Oil Temperature and gear, is carried out the flow of fluid in oil circuit control.When gearbox gear wheel speed is higher, oil temperature is higher time, the selector valve of control module in can oil circuit control, make fluid through refrigerating module carry out further cooling after, then enter spray bar 7; When gearbox gear wheel speed is lower, oil temperature is lower time, the selector valve 5 in control module oil circuit control, makes oil circuit directly enter spray bar 7 without refrigerating module 6.After fluid enters spray bar, on spray bar, have towards the axial several nozzle openings 9 of tooth, under the High Pressure of fluid, parts of lubricating oil is ejected into and is needed on lubricated gear and synchronizer by the nozzle opening 9 on spray bar 7.The position of nozzle opening 9 and quantity and gear 13 and synchronizer match.Lubricant oil under residue can enter from the other end of spray bar 7 the low pressure oil duct of end cap, and bearing support 8 UNICOMs of the low pressure oil duct of end cap and gear-box axle system, introduce bearing support 8 by lubricant oil, and the bearing of work is lubricated with cooling.
As shown in Figure 3, spray bar body 10 is hollow metal tubes, O type circle 12 is installed on the filler opening of spray bar body 10, then on metal pipe-wall, be equipped with several nozzle openings 9, while considering work, nozzle opening 9 is had to orientation requirement, on metal pipe-wall, weld a fixed support 11, when assembling, only need to will in the respective aperture of the nozzle opening of spray bar 79 and fixed support 11 insertion end caps, can complete.
The lubrication system of the utility model gearbox has been used the mode of pressure lubrication, after fluid enters spray bar, on spray bar, have towards the axial several apertures of tooth, under the High Pressure of fluid, parts of lubricating oil, is lubricated dual-clutch transmission gear and the bearing of operating mode complexity by the small hole injection on spray bar to the lubricated gear and synchronizer of needs.Control module is by gathering the rotating speed of TOT Transmission Oil Temperature and gear, control selector valve in lubricating oil path and determine the fluid refrigerating module of whether flowing through, the lubricating efficiency not only improving to a great extent, but also improved wearing and tearing and the sintering character preventing between gear and gear, axle and bearing; By the regulation and control to flow of lubrication and oil circuit, effectively improved the working efficiency of gearbox simultaneously.And spray bar is by the fixed support being welded thereon, and when assembling, only need to, by completing in the respective aperture of the oil outlet of spray bar and fixed support insertion end cap, simplify production technology and assembly technology.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's scope.
