Abstract
The utility model discloses a kind of Automobile drive axle shell assemblies, belong to Automobile drive vehicle bridge field, the purpose of this utility model is solved in the punching-welding axle housing of driving vehicle bridge at present, weld strength between axle housing rear cover and axle housing is low, the problem of there is cold wind cracking in use process, leading to oil leak；Circular weld is mostly in the excessive position of the fillet of axle housing, the problem of increasing welding difficulty；The problem of material that axle housing occupies is more, increases weight and cost.Axle housing rear cover is embedded in the inner stopper of axle housing using round inner stopper structure, and uses inside and outside twice annular solder design, improves weld strength；Circular weld reduces welding difficulty in the plan-position of axle housing；The inner stopper larger of axle housing reduces the weight and cost of axle housing.
Description
Technical field
The utility model belongs to Automobile drive vehicle bridge field, and in particular to a kind of novel axle housing rear cover.
Background technique
In current driving vehicle bridge, welding form is used between the axle housing rear cover and axle housing of punching-welding axle housing, after axle housing
Lid mostly uses outer turnup structure, and the plane of flange is docked with axle housing plane, welded using welding ring-shaped fillet weld.Such knot
Structure, the weld strength between axle housing rear cover and axle housing is low, cold wind cracking in use process often occurs, leads to asking for oil leak
Topic；Circular weld mostly in the excessive position of the fillet of axle housing, increases welding difficulty；The material that axle housing occupies is more, increases
Add weight and cost.
Summary of the invention
The purpose of this utility model is solved in the punching-welding axle housing of driving vehicle bridge at present, between axle housing rear cover and axle housing
Weld strength it is low, there is in use process the problem of cold wind cracks, leads to oil leak；Circular weld is mostly in the fillet of axle housing
The problem of excessive position, increase welding difficulty；The problem of material that axle housing occupies is more, increases weight and cost.
The technical solution adopted in the utility model is as follows:
A kind of Automobile drive axle shell assembly, including 1 two parts of axle housing rear cover 2 and axle housing, intermediate axle shell rear cover 2
It is equipped with male half coupling 3 with the endface position that axle housing 1 cooperates, the endface position that axle housing 1 cooperates with axle housing rear cover 2 is equipped with
The male half coupling 3 of inner stopper 4, axle housing rear cover 2 is fitted into the inner stopper 4 of axle housing 1, shoulder and the axle housing 1 of male half coupling 3
End face cooperation, axle housing rear cover 2 and axle housing 1 are connected as one by welding manner.
The inside of 1 inner stopper 4 of axle housing is equipped with welding groove 8, welding groove 8 and the axle housing rear cover 2 of axle housing 1
It is welded between male half coupling 3 using welding ring-shaped fillet weld；Annular angle is used between the diameter of axle of axle housing rear cover 2 and the end face of axle housing 1
Weld seam welding.
The beneficial effects of the utility model are:
Axle housing rear cover is embedded in the inner stopper of axle housing using round inner stopper structure, and using inside and outside twice annular
Solder design improves weld strength；Circular weld reduces welding difficulty in the plan-position of axle housing；Axle housing
Inner stopper larger, reduce the weight and cost of axle housing.

Fastening.
Such as a kind of Automobile drive axle shell assembly of Fig. 1, including 1 two parts of axle housing rear cover 2 and axle housing, intermediate axle shell
The endface position that rear cover 2 and axle housing 1 cooperate is equipped with male half coupling 3, the endface position that axle housing 1 and axle housing rear cover 2 cooperate
It is equipped with inner stopper 4, the male half coupling 3 of axle housing rear cover 2 is fitted into the inner stopper 4 of axle housing 1, the shoulder and axle housing of male half coupling 3
The end face of ontology 1 cooperates, and axle housing rear cover 2 and axle housing 1 are connected as one by welding manner.
The inside of 1 inner stopper 4 of axle housing is equipped with welding groove 8, welding groove 8 and the axle housing rear cover 2 of axle housing 1
It is welded between male half coupling 3 using welding ring-shaped fillet weld；Annular angle is used between the diameter of axle of axle housing rear cover 2 and the end face of axle housing 1
Weld seam welding.
Axle housing rear cover view as shown in Figure 3, using round male half coupling 3, for cooperating with the inner stopper of axle housing 1,
And it is used for welding surface.
Axle housing view as shown in Figure 4, using round inner stopper 4, for cooperating with the male half coupling of axle housing rear cover 2；
Using welding groove 8, it to be used for welding surface.
