Abstract
The utility model provides a welding structure of spindle nose and axle housing body, through increase the shape ring recess on the bush, for original no recess bush structure, increased the depth of annular welding to the corresponding distance that increases between the terminal surface of spindle nose and the terminal surface of axle housing body has promoted the welding liquid capacity, has increased the number of turns of annular weld, has promoted the penetration rate, has promoted the welding reliability; in order to conveniently install the bush into the shaft head and the axle housing body, the outer wall of the bush is provided with a notch which is through along the axial direction of the bush and used for adjusting the diameter of the bush during assembly.
Description
Technical Field
The utility model belongs to car axle subassembly field, concretely relates to welded structure of spindle nose and axle housing body.
Background
In the present domestic car axle, adopt between the axle housing body of stamping structure and the spindle nose to butt welding structure more to adopt annular bush structure, the axle footpath of annular bush forms annular groove with the terminal surface of axle housing body, the terminal surface of spindle nose, is used for holding the welding liquid. To the thin light-duty axle product of axle housing body wall thickness, influenced by factors such as temperature, welding seam degree of depth, the penetration rate of axle housing body and spindle nose is lower, has seriously reduced welding strength, leads to axle housing assembly bearing capacity to reduce the scheduling problem.
Disclosure of Invention
The utility model discloses a solve among the light-duty axle of current car because the thin annular groove's that leads to welding axle housing assembly of the wall thickness of axle housing body volume less, the welding liquid volume that holds of annular groove that forms of axle housing body, spindle nose terminal surface, bush shaft diameter is not enough, and then lead to axle housing body and spindle nose weld through the rate low, the welding strength seriously descends, the bearing capacity of axle housing assembly reduces the scheduling problem, provide a welded structure of spindle nose and axle housing body to promote the bearing reliability of axle housing assembly.
The utility model discloses an adopt following technical scheme to realize:
a welding structure of a shaft head and an axle housing body is applied to an axle housing assembly and comprises the shaft head and the axle housing body, an annular bushing is connected with the shaft head and the axle housing body, it is characterized in that the middle part of the outer surface of the bushing is provided with an annular groove, so that the bushing forms two shaft necks of the bushing on two sides of the annular groove, one shaft neck of the bushing is arranged in a circular hole of the shaft head, the front end surface of the bushing is attached to a round angle in the circular hole of the shaft head for axial limiting, the other shaft neck of the shaft sleeve is arranged in a circular hole of the axle housing body, there is 5 ~ 7 mm's clearance between the terminal surface of spindle nose and the terminal surface of axle housing body, and the notch of the annular groove of bush is located the top in the clearance between spindle nose and the axle housing body, adopts the circular weld welding to fill the space that is formed by the annular groove of bush and the clearance between spindle nose and the axle housing body, links together spindle nose, bush and axle housing body.
The further technical scheme is as follows:
the outer wall of the bushing is provided with a notch which is through along the axial direction of the bushing and is used for adjusting the diameter of the bushing during assembly so as to facilitate assembly.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a pair of welded structure of spindle nose and axle housing body through increase shape ring recess on the bush, for original no recess bush structure, increased annular welded degree of depth to corresponding increase the distance between the terminal surface of spindle nose and the terminal surface of axle housing body, promoted the welding liquid capacity, increased the number of turns of circumferential weld, promoted the penetration rate, promoted the welding reliability. In order to conveniently install the bush 2 into the spindle nose 1 and the axle housing body 3, the outer wall of the bush 2 is provided with a notch 4 which is through along the axial direction of the bush 2 and is used for adjusting the diameter of the bush 2 during assembly.

fig. 1 is a partial cross-sectional view of a welding structure of a spindle head and an axle housing body applied to an axle housing assembly according to the present invention;
fig. 2 is a partial enlarged view at a position I in fig. 1, namely, a structural schematic view of a welding structure of a spindle head and an axle housing body according to the present invention;
fig. 3 is an axial view of a bushing in a welding structure of a spindle head and an axle housing body according to the present invention;
fig. 4 is a cross-sectional view of a bushing in a welding structure of a spindle head and an axle housing body according to the present invention;
in the figure: 1. the novel axle housing comprises a spindle head, 2 parts of a lining, 3 parts of an axle housing body, 4 parts of a notch and 5 parts of an annular groove.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
the utility model provides a welding structure of a shaft head and an axle housing body, which is applied to an axle housing assembly as shown in figure 1, and comprises a shaft head 1 and an axle housing body 3, wherein an annular bush 2 is connected with the shaft head 1 and the axle housing body 3;
as shown in fig. 4, there is annular groove 5 in the middle part of the surface of bush 2, make bush 2 form two journals of bush 2 in the both sides of annular groove 5, as shown in fig. 1, one of them journal of bush 2 is packed into in the round hole of spindle nose 1 and the fillet laminating in the preceding terminal surface of bush 2 and the round hole of spindle nose 1 is used for axial spacing, another journal of bush 2 is packed into in the round hole of axle housing body 3, there is 6 mm's clearance between the terminal surface of spindle nose 1 and the terminal surface of axle housing body 3, the notch of annular groove 5 of bush 2 is located the top in the clearance between spindle nose 1 and the axle housing body 3, adopt the space that annular weld welding fills and is formed by the annular groove of bush 2 and the clearance between spindle nose 1 and the axle housing body 3, link together spindle nose 1, bush 2 and axle housing body 3. This structure can realize the increase in the clearance between the terminal surface of spindle nose 1 and the terminal surface of axle housing body 3 to the annular groove 5 of cooperation bush 2 has increased the capacity of welding liquid in the welding process, has increased the number of turns of circumferential weld, has promoted the penetration rate, has promoted welding reliability.
In order to conveniently install the bush 2 into the spindle nose 1 and the axle housing body 3, the outer wall of the bush 2 is provided with a notch 4 which is through along the axial direction of the bush 2 and is used for adjusting the diameter of the bush 2 during assembly.
