Abstract
The utility model belongs to automotive transmission class, a specifically speed changer two axle Rear oil seal safeguard structure, comprise rear case, back skeleton, output flange, back skeleton is contained in rear case, it is characterized in that: rear case is provided with the dirty transmission groove of storage, the dirty transmission groove bottom of this storage is provided with a small through hole; Output flange is equipped with oil sealing protective ring, oil sealing protective ring is provided with multidisc protection lip and gets rid of dirty circle, and multidisc protection lip contact with the endoporus of rear case, gets rid of that dirty to enclose position corresponding with the storage dirt transmission groove on rear case.During utility model works, most water greasy dirt, sand dust soil etc. will be kept off in the outside of two axle Rear oil seals by the multidisc lip of oil sealing protective ring, the liquid such as the water greasy dirt entered on a small quantity also will be got rid of dirty circle and be thrown to rear case and store up in dirty transmission groove and discharge, thus the applying working condition of automotive transmission two axle Rear oil seal is improved greatly, the working life of two axle Rear oil seals significantly improves.
Description
Technical field
The utility model belongs to automotive transmission class, specifically a kind of speed changer two axle Rear oil seal safeguard structure.
Background technique
Oil sealing is the vitals in automotive transmission, and sealability is the important indicator of transmission reliability, and current state inner oil seal early failue causes seepage oil condition more serious.Two axle Rear oil seals assembling situations are substantially as follows: two axle Rear oil seals generally adopt outside framework oil seal, are pressed in rear case or bonnet during assembling, fill a protecting cover while of some on output flange, but it and rear case or after be stamped comparatively wide arc gap; Also some speed changer two axle Rear oil seal is without any safeguard structure, and two axle Rear oil seals are exposed to outside completely, and the secondary lip only by oil sealing protects.Because the applying working condition of automotive transmission two axle Rear oil seal is severe, water greasy dirt, sand dust soil etc. is easy to enter two axle Rear oil seals, causes oil seal lip and working surface early failue, leakage of oil fault occurs.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides the speed changer two axle Rear oil seal safeguard structure that a kind of structure is simple, easy for installation, cost is low.
The technical solution of the utility model is as follows:
A safeguard structure for speed changer two axle Rear oil seal, comprise rear case, back skeleton, output flange, back skeleton is contained in rear case, it is characterized in that: rear case is provided with the dirty transmission groove of storage, and the dirty transmission groove bottom of this storage is provided with a small through hole; Output flange is equipped with oil sealing protective ring, oil sealing protective ring is provided with multidisc protection lip and gets rid of dirty circle, and multidisc protection lip contact with the endoporus of rear case, gets rid of that dirty to enclose position corresponding with the storage dirt transmission groove on rear case.
The utility model is because oil sealing protective ring is with multidisc protection lip and get rid of dirty circle, during work, most water greasy dirt, sand dust soil waits and keeps off by the multidisc lip of oil sealing protective ring in the outside of two axle Rear oil seals, because output flange is with oil sealing protective ring High Rotation Speed, the liquid such as the water greasy dirt entered on a small quantity also will be enclosed in the dirty transmission groove of the storage be thrown on rear case or bonnet by the dirt of getting rid of of oil sealing protective ring, this soiling solution is finally discharged by the small through hole of the dirty transmission groove bottom of storage, thus the applying working condition of automotive transmission two axle Rear oil seal is improved greatly, the working life of two axle Rear oil seals significantly improves.The utility model structure is simple, and easy for installation, cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a safeguard structure for speed changer two axle Rear oil seal, comprises rear case 1, back skeleton 2, output flange 4, and back skeleton 2 is contained in rear case 1, it is characterized in that: rear case 1 is provided with the dirty transmission groove of storage, the dirty transmission groove bottom of this storage is provided with a small through hole; Output flange 4 is equipped with oil sealing protective ring 3, oil sealing protective ring 3 is provided with multidisc protection lip and gets rid of dirty circle, and multidisc protection lip contact with the endoporus of rear case 1, gets rid of that dirty to enclose position corresponding with the storage dirt transmission groove on rear case.
During utility model works, most water greasy dirt, sand dust soil etc. will be kept off in the outside of two axle Rear oil seals by the multidisc lip of oil sealing protective ring 3, because output flange 4 is with oil sealing protective ring 3 High Rotation Speed, the liquid such as the water greasy dirt entered on a small quantity also enclose by the dirt of getting rid of of oil sealing protective ring 3 in the dirty transmission groove of the storage be thrown on rear case 1 or bonnet, and this soiling solution is finally discharged by the small through hole of the dirty transmission groove bottom of storage.Because applying working condition obviously improves, the working life of two axle Rear oil seals significantly improves.
