Abstract
The utility model discloses a kind of half shaft Lightened structures, belong to automobile drive axle technical field, including semiaxis and ring flange, and ring flange is provided on the semiaxis, and the center of the ring flange is provided with speaker hole shape through-hole, are used for loss of weight；The edge of speaker hole shape through-hole is arranged symmetrically, and there are two blind round hole, for installing finger；Several flange holes are evenly arranged on the flange of ring flange, for connecting wheel hub；The semiaxis uses spline shaft structure, for connecting axle shaft gear.The half shaft Lightened structure of the utility model alleviates material weight using the loudspeaker keyhole-shaped recess structure at end face of flange center；End face of flange uses two uniformly distributed blind round hole structures, for installing finger, reduces the weight of former finger and semiaxis forging integral structure.
Description
Technical field
The utility model belongs to automobile drive axle technical field, and in particular to a kind of half shaft Lightened structure.
Background technique
In domestic drive axle, the end face of flange of half shaft mostly uses planar structure, and increases one or two forgings and dial
Block, switch semiaxis when for processing.These kind of structure, the center of end face of flange are not subject to torque, and excess stock increases
Weight；Forging shifting block does not play a role in vehicle bridge operation, but increases weight.
Utility model content
To solve in existing drive axle, the big problem of semiaxis weight, the utility model provides a kind of half shaft and subtracts
Weight structure.
The utility model is achieved through the following technical solutions:
A kind of half shaft Lightened structure, including semiaxis 1 and ring flange are provided with ring flange on the semiaxis 1, described
The center of ring flange is provided with speaker hole shape through-hole 11, is used for loss of weight；The edge of speaker hole shape through-hole 11 is symmetrically arranged with
Two blind round hole 12, for installing finger 4；It is evenly arranged with several flange holes 13 on the flange of ring flange, is used for fifth wheel
Hub；The semiaxis 1 uses spline shaft structure, for connecting axle shaft gear.
Compared with prior art, as follows the advantages of the utility model:
The half shaft Lightened structure of the utility model is subtracted using the loudspeaker keyhole-shaped recess structure at end face of flange center
Light material weight；End face of flange uses two uniformly distributed blind round hole structures, for installing finger, reduces former finger and half
The weight of axis forging integral structure.
Detailed description of the invention
Fig. 1 is a kind of main view of half shaft Lightened structure of the utility model；
Fig. 2 is a kind of side view of half shaft Lightened structure of the utility model；
Fig. 3 is a kind of installation diagram of half shaft Lightened structure of the utility model；
In figure: semiaxis 1, bolt 2, wheel hub 3, finger 4, loudspeaker keyhole-shaped recess 11, blind round hole 12, flange hole 13.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Embodiment 1
A kind of half shaft Lightened structure, including semiaxis 1 and ring flange are provided with ring flange on the semiaxis 1, described
The center of ring flange is provided with speaker hole shape through-hole 11, is used for loss of weight；The edge of speaker hole shape through-hole 11 is symmetrically arranged with
Two blind round hole 12, for installing finger 4；It is evenly arranged with several flange holes 13 on the flange of ring flange, is used for fifth wheel
Hub；The semiaxis 1 uses spline shaft structure, for connecting axle shaft gear.
A kind of assembly method of the half shaft Lightened structure and driving axis of the utility model, specific as follows:
The flange hole 13 of semiaxis 1 is aligned with the threaded hole of wheel hub 3, and the splined shaft of semiaxis 1 and the splined hole of axle shaft gear are matched
It closes；Bolt 2 screws in wheel hub 3 by the flange hole 13 of semiaxis 1 and tightens.Wherein, blind round hole 12 is used for blind round hole 12, finger
4 are only used for processing, and when assembling drive axle, unload finger 4.
