Description
Technical field
The utility model belongs to automobile drive axle lubrication technical field, in particular to a kind of drive axle lubrication oil filtration system
System.
Background technique
As domestic heavy truck market competition is more fierce, vehicle requires also to get over to the service life of the crucial assembly such as drive axle
Come higher.While the car is driving, due to the particularity of metal parts, the secondary constantly contact of the friction such as gear, bearing, bushing
Operating can be worn, and the iron filings for wearing generation are mixed into lubricating oil, can be caused seriously to the cleannes of lubricating oil in drive axle
It influences.If not replacing in time to the lubricating oil polluted at this time, the lubricant effect of lubricating oil in drive axle will be reduced,
And then seriously affect the service life of driving axis.But the periodic replacement of lubricating oil not only will increase the use cost of vehicle with
The time cost of maintenance also can cause environmental pollution if the waste lubrication oil after replacing is dealt with improperly.
For the cleannes of lubricating oil in constantly improve drive axle, effectively extend the replacement cycle of lubricating oil, effective side
Method is the installation filter mechanism on drive axle.In drive axle operation process, lubricating oil inside axle housing is with from mantle tooth
The rotation of wheel is splashed, and oil inlet is arranged on the path that lubricating oil flows through at this time, and lubricating oil is allowed to flow through filter by inertia
Net, the filtering of energy simple realization lubricating oil.But existing drive axle filter mechanism is in order to avoid the gravity due to lubricating oil
Loss causes lubricating oil unsmooth in filter internal flow, and usually filter oil inlet is arranged above mechanism, and lubricating oil is only
It can be reflected into filter by baffle, not can guarantee the filtering efficiency of lubricating oil.
Therefore, under the premise of not changing existing drive axle lubricating system, providing a kind of is that lubricating oil continues efficiently to pass through
The problem of filtration system that strainer screen provides power becomes urgent need to resolve.
Summary of the invention
The purpose of the utility model is to provide a kind of drive axle lubrication oil filtration systems, by changing filter mechanism
Oil inlet mode, efficiently asking by strainer screen can not be continued by fundamentally solving lubricating oil in drive axle filter mechanism
Topic；Meanwhile can be by the periodic replacement to filter, the control for thoroughly solving drive axle internal lubrication luboil cleanness is asked with promotion
Topic, greatly improves the service life of driving axis.
The purpose of this utility model is achieved through the following technical solutions:
A kind of drive axle lubrication oil filtration system, including the driven wheel of differential 2 inside axle housing 1 and axle housing 1, filter bottom
Seat 3, pedestal backing plate 4 and filter body 5, the cleaner case 3 are fixed on outside axle housing 1 by pedestal backing plate 4, are filtered
Clear device pedestal 3 is connected through a screw thread with filter body 5, there is circular filter net 52 inside the filter body 5, described
Cleaner case 3 includes oil inlet pipe 31, collection chamber 32, flowline 33, oil outlet chamber 34 and connects for installing filter body 5
Annular groove 35, the oil inlet pipe 31 are connected to collection chamber 32, and the flowline 33 is connected to oil outlet chamber 34, annular mistake
Strainer 52 is resisted against on the shoulder 37 of flowline 33, offers oil suction chamber between the shoulder 37 and annular groove 35 of flowline 33,
Oil suction chamber is connected to collection chamber 32, and oil inlet passage 51 is formed between filter body 5, circular filter net 52 and oil suction chamber, described
Oil inlet pipe 31 pedestal lower half portion and along the tangential direction of driven wheel of differential 2 arrange.
As the utility model, more preferably there is annular projection 36 at technical solution, the inner ring edge of the annular groove 35,
There is a groove matched with annular projection 36 in the annular outer cover end face of the filter body 5, forms blocking face, ensure that into
The leakproofness in oily channel 51.
It has the beneficial effect that:
For the utility model by simple structure, height can not be continued by solving lubricating oil in the application process of drive axle filter
The problem of effect passes through strainer screen, can regularly replace filter, can effectively extend the use of lubricating oil of drive axle
Period, and then extend the service life of entire driving axis, it is only necessary to covered after existing axle housing restructure it is just achievable
The installation of a whole set of filter mechanism can be applied directly on existing drive axle product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the lubricating oil of the utility model flows to schematic diagram；
The structural schematic diagram of the pedestal of Fig. 3 the utility model；
The structural schematic diagram of the pedestal of Fig. 4 the utility model.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in figs. 1 and 3, the utility model provides a kind of drive axle lubrication oil filtration system, including axle housing 1 and axle housing
Driven wheel of differential 2, cleaner case 3, pedestal backing plate 4 and filter body 5, the cleaner case 3 inside 1 pass through
Pedestal backing plate 4 is fixed on outside axle housing 1, and cleaner case 3 is connected through a screw thread with filter body 5, the filter sheet
There is circular filter net 52 inside body 5, the cleaner case 3 includes oil inlet pipe 31, collection chamber 32, flowline 33, oil outlet chamber
34 and the annular groove 35 for installing the connection of filter body 5, the oil inlet pipe 31 is connected to collection chamber 32, it is described out
Oil pipe 33 is connected to oil outlet chamber 34, and circular filter net 52 is resisted against on the shoulder 37 of flowline 33,37 He of shoulder of flowline 33
Oil suction chamber is offered between annular groove 35, oil suction chamber is connected to collection chamber 32, filter body 5, circular filter net 52 and into
