Connected unit is provided with, the surface of the connected unit offers bearing neck, and the right side wall center of the connected unit is provided with axle master
Body, the inner chamber of the axle main body offers through hole, and through hole direction perpendicular to the right sidewall surface of connected unit, the axle main body
Right side be provided with spline, and axle main body is located at the left side wall center of spline.
It is preferred that, by being welded between axle main body and spline between the connected unit and axle main body.
It is preferred that, periphery, blind hole intracavity bottom periphery, support shoulder and the ring flange of the support shoulder left side wall
Junction, the right side wall periphery of the junction of transition cone and connected unit and connected unit be provided with rounding.
It is preferred that, the outer wall of the axle main body scribbles fluorocarbon-sprayed coating.
Compared with prior art, the beneficial effects of the utility model are：Compared with existing automobile axle shaft structure, this practicality
New structure is simple, and easy to use, the utility model is improved existing automobile axle shaft structure, by orthodox car semiaxis
The structure of integration forging is modified to the form of multistage welding, can so reduce automobile axle shaft when being heat-treated
Heat distortion amount, and overall structure of the present utility model is the shape of symmetrical expression, is provided with chamfering in crossover position, so also may be used
To reduce heat distortion amount of the automobile axle shaft when being heat-treated.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 support shoulder, 2 blind holes, 3 ring flanges, 4 bolts hole, 5 transition cones, 6 connected units, 7 bearing necks, 8 axle masters
Body, 9 through holes, 10 splines.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of small automobile axle shaft structure of thermal deformation, including
Support shoulder 1, the left side wall of support shoulder 1 offers blind hole 2, and the right side wall center of support shoulder 1 is provided with ring flange 3, and branch
Hold shoulder 1 and be symmetrically arranged with bolt hole 4, method at the top and bottom of the left side wall center of ring flange 3, the left side wall of ring flange 3
The right side wall center of blue disk 3 is provided with transition cone 5, and the right side wall center of transition cone 5 is provided with connected unit
6, the surface of connected unit 6 offers bearing neck 7, and the right side wall center of connected unit 6 is provided with axle main body 8, the inner chamber of axle main body 8
Offer through hole 9, and through hole 9 direction perpendicular to the right sidewall surface of connected unit 6, the right side of axle main body 8 is provided with spline 10,
And axle main body 8 is located at the left side wall center of spline 10.
Wherein, between connected unit 6 and axle main body 8 between axle main body 8 and spline 10 by being welded, support shoulder 1
The junction of the periphery of left side wall, the intracavity bottom periphery of blind hole 2, support shoulder 1 and ring flange 3, transition cone 5 with
The junction of connected unit 6 and the right side wall periphery of connected unit 6 are provided with rounding, so reduce the rib that part occurs
Angle so that the transition between component more relaxes, and then the heat distortion amount between them can be reduced, the outer wall of axle main body 8 is scribbled
Fluorocarbon-sprayed coating, fluorocarbon-sprayed coating has good anticorrosion and antioxidation, can so slow down the oxygen of axle main body 8
Change speed.
Operation principle：Several parts are separately heat-treated, several portions by automobile axle shaft of the present utility model in production
Part is respectively that spline 10, axle main body 8 and the part lefted in are overall, and the shape of so each part is relatively regular, and each
Part thickness will be than more uniform, and section power is uniformly dispersed, and so reduces transition region stress and concentrates and produce distortion
With the tendency of cracking, and because each part remain the symmetrical of structure, can so reduce heat treatment inhomogeneous cooling caused by
Distortion, heat treatment thermal change when heat distortion amount when now each part is separately heat-treated will be heat-treated than unified entirety
Shape amount is small, and the structure for the semiaxis head component that support shoulder 1, ring flange 3, transition cone 5 and connected unit 6 are constituted is relatively
Complexity, when being heat-treated, heat distortion amount can be larger, and periphery, the intracavity bottom of blind hole 2 due to the left side wall of support shoulder 1
Periphery, support shoulder 1 and the junction of ring flange 3, transition cone 5 and the junction and the right side of connected unit 6 of connected unit 6
Wall periphery has rounding, so reduces the corner angle that part occurs so that the transition between component more relaxes, Jin Erke
To reduce the heat distortion amount between them, the materials of axle main body 8 can be reduced by opening up through hole 9 in the inner chamber of axle main body 8, so may be used
To save material, and alleviate the overall weight of semiaxis.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
