Above-mentioned bull-dozer transfer case independent lubricating system, it is described to divide font to be provided with pressure-reducing valve, the pressure release oil of the pressure-reducing valve Mouth is inside transfer case.
Above-mentioned bull-dozer transfer case independent lubricating system, it is described to divide font to divide font and pair to divide font to form by master, it is described The flowline of the main oil inlet pipe for dividing font and grease pump connects, and the pair divides the oil inlet of font to pass through connecting tube and main point of oil Seat connection, multiple lubrication managements are divided into two groups, and the oil inlet end of two groups of lubrication managements divides font and pair to divide font to be connected with master respectively.
Above-mentioned bull-dozer transfer case independent lubricating system, also include magnetic plug cock in composition, the magnetic plug cock is pacified by screw thread Mounted in the bottom of transfer case.
Above-mentioned bull-dozer transfer case independent lubricating system, also include dipstick component in composition, the dipstick component is arranged on The side of transfer case.
Above-mentioned bull-dozer transfer case independent lubricating system, vent hood assembly, the vent hood assembly peace are also included in composition Mounted in the top of transfer case.
The grease pump that the utility model is driven by walking pump gear provides power, and lubrication hydraulic oil is transported into a point oil Seat, then fluid is assigned to by lubrication management each oil site of transfer case, the bearing inside transfer case and gear are forced Lubrication, so as to ensure that the lubricant effect of transfer case, extends the service life of transfer case.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure respectively marked as:1st, magnetic plug cock, 2, filter, 3, oil inlet pipe, 4, fuel sucking pipe, 5, flowline, 6, grease pump, 7th, the first lubrication management, the 8, second lubrication management, the 9, the 3rd lubrication management, 10, pressure-reducing valve, 11, it is main divide font, 12, connecting tube, 13, logical Gas hood assembly, the 14, the 4th lubrication management, the 15, the 5th lubrication management, 16, dipstick component, 17, pair divide font, the 18, the 6th lubrication management.
Embodiment
The utility model realizes the independent lubricating of bull-dozer transfer case, solve hydrostatic chassis of bulldozer hydraulic system without Method provides the problem of lubricating oil.
Referring to Fig. 1, the utility model mainly divides font including magnetic plug cock 1, filter 2, grease pump 6, pressure-reducing valve 10, master 11st, vent hood assembly 13, dipstick component 16, pair divide font 17 and multiple lubrication managements.
From fig. 1, it can be seen that filter 2 is arranged in transfer case bottom mounting apertures, it is bolted, installation surface passes through paper Pad sealing;Grease pump 6 is assemblied in transfer case mounting hole by seam positioning, and is fastened by bolts, the suction of grease pump 6 Oil pipe 4 is connected with filter 2;Main to divide font 11 and pair to divide font 17 to be arranged on by bolt in transfer casing, pressure-reducing valve 10 is pacified Divide mounted in master on font 11, master divides font 11 and pressure-reducing valve 10 to be fastened by bolts on casing, and pressure-reducing valve 10 passes through oil inlet pipe 3 It is connected with flowline 5 with grease pump 6, master divides font 11 to divide by the first lubrication management 7, the second lubrication management 8, the 3rd lubrication management 9 It is not connected with oil site at transfer casing three, and divides font 17 to be connected with pair by connecting tube 12;Pair divides font 17 to pass through 4th lubrication management 14, the 5th lubrication management 15, the 6th lubrication management 18 respectively with other of transfer case at three oil site be connected;Ventilation Cover assembly 13 is by being threadably mounted at transfer casing top, and magnetic plug cock 1 is by being threadably mounted at transfer casing bottom;Dipstick component 16 are bolted in transfer casing.
Grease pump 6 is gear pump, is connected by spline with transfer case walking pump gear, when bull-dozer works, walking Pump gear drives grease pump 6 to work, and lubrication hydraulic oil is sucked by transfer case bottom by filter 2, subsequently into pressure-reducing valve 10, Pressure-reducing valve 10 plays a part of protecting hydraulic system, and when lubricating system pressure rise exceedes rated pressure, pressure-reducing valve 10 works, Lubrication pressure release hydraulic fluid port of the hydraulic oil through pressure-reducing valve 10 is flowed into transfer case, is let out when system pressure declines and reaches specification requirement Press oil port is closed.Lubrication hydraulic oil flows into master through pressure-reducing valve 10 and divided in font 11, and master divides the effect of font 11 to be to enter hydraulic oil Row distribution, wherein three road hydraulic oil are directly connected with oil site at the three of transfer case, another way divides font 17 to be connected with pair, secondary Divide font 17 that hydraulic oil is divided into three tunnels again, be connected respectively with oil site at its excess-three of transfer case.
Magnetic plug cock 1, which is arranged on transfer case bottom, to be responsible for adsorbing the metal impurities in transfer case in hydraulic oil, repairs transfer case When, the hydraulic oil in transfer case can be easily bled off by magnetic plug cock 1.Vent hood assembly 13 can will be unnecessary in transfer case Air is discharged, and is prevented the negative pressure state that builds the pressure and formed, is prevented cavitation.Dipstick component is arranged on outside transfer casing, The liquid level of hydraulic oil in transfer casing can be measured, avoiding refueling excessively causes system heat generation, very few prevented also from oil mass Generation oil pump emptying phenomenon, oil dipstick tube are arranged on outside casing, you can are improved operational reliability, can be avoided because after bolt looseness again Fall into damage internal gear in casing.
