Bearing premature wear certainly of the existing technology or even ablation penetrate through axle fracture, beat a series of deficiency of failures such as tooth, spring tooth
Place.
The technical solution for solving above-mentioned technical problem is: a kind of band gets rid of the integral type main gearbox assembly of oily blade, including
It is poor between integral housing, the main reducing gear in integral housing, inter-axle differential and wheel outside integral housing
Fast device, inter-wheel differential include differential carrier, the differential mechanism in differential carrier, are also connected with and get rid of on the differential carrier
Oily blade.
A further technical solution of the present invention is: the oily blade that gets rid of is the structure that is vertically formed by connecting by the end face A and the end face B
At approximate 7 character form structures, the end face A for getting rid of oily blade is bonded with differential carrier end face, which is used for and differential equipped with one
The connecting hole of device shell connection；The end face B is bonded with differential carrier periphery, and the end face B is outside with differential carrier outer circle joint place
Tilting has the edge that oil is got rid of for frizing.
The further technical solution of the present invention is: the edge is broken line.
The further technical solution of the present invention is: the differential carrier includes differential mechanism left housing, differential right casing, it is poor
It is bolted together between fast device left housing, differential right casing；The end face A and differential right casing end face for getting rid of oily blade are pasted
It closes, the connecting hole on the end face A passes through the bolt, and the end face B for getting rid of oily blade is bonded with differential right casing periphery.
Since using the above structure, the band of the present invention gets rid of the integral type main gearbox assembly and prior art phase of oily blade
Than having the advantages that
1. rear axle shaft gear bearing and perforation axle bearing can be made to obtain sufficient lubrication:
Since the present invention includes integral housing, the main reducing gear in integral housing, inter-axle differential and position
In the inter-wheel differential outside integral housing, wherein inter-wheel differential includes differential carrier, differential mechanism, and is gone back on the differential housing
It being connected with and gets rid of oily blade, i.e., the present invention is to be connected with to get rid of oily blade on the differential carrier of existing integral type main gearbox assembly,
The lubricating oil under axle housing can be thrown on rear axle shaft gear bearing and perforation axle bearing by getting rid of oily blade by this, after making
Axle shaft gear bearing and perforation axle bearing obtain sufficient lubrication.
2. avoidable bearing premature wear, ablation and perforation axle fracture:
Since lubricating oil can be thrown on perforation axle bearing by the present invention by getting rid of oily blade, perforation axle bearing can be made to be filled
Cunning of sharing in the benefit also can avoid perforation axle fracture to can avoid bearing premature wear, ablation.
3. can avoid beating the failures such as tooth, spring tooth:
Since lubricating oil can be thrown on rear axle shaft gear bearing by the present invention by getting rid of oily blade, rear side gear shaft can be made
It holds to obtain sufficient lubrication, to can avoid beating a series of failures such as tooth, spring tooth.
4. achieving the purpose that reduce noise, reducing failure, prolong the service life:
Due to the present invention can make rear axle shaft gear bearing and perforation axle bearing obtain sufficient lubrication, reached reduction noise,
The purpose for reducing failure, prolonging the service life.
5. structure is simple, overall cost is low:
Overall structure of the invention is fairly simple, and overall cost is low, use easy to spread.
In the following, the technology for getting rid of the integral type main gearbox assembly of oily blade to the band of the present invention in conjunction with the accompanying drawings and embodiments is special
Sign is further described.
