The invention provides a kind of automotive axle semi-axis structure, including the flange of interconnection and semiaxis bar portion, one end that the semiaxis bar portion is connected with the flange is flange end, and the other end is splined end, wherein the half shafts portion is in hollow form.The technical scheme is improved the structure of semiaxis, the weight for alleviating semiaxis simultaneously on the premise of ensureing that transmission moment of torsion is constant reaches vehicle loss of weight, saves material, energy-saving consumption-reducing, in addition, quality is lighter, the anti-twisting property that reaches during more convenient during the semiaxis bar portion processing of hollow form, heat treatment is higher than solid semiaxis, hollow semiaxis can improve bending adaptability, semiaxis fatigue resistance can be improved simultaneously, improve service life；Hollow semiaxis is easy to flaw detection, makes finished product semiaxis reliability stronger, more secure when used.
Description
Technical field
The present invention relates to a kind of automotive axle semi-axis structure, belong to technical field of automobile components.
Background technology
Automotive axle is one of critical piece of automobile, and vehicle bridge divides steeraxle (steering and driving axle) and drive axle, turns to and drives
The power that engine provides is transmitted moment of torsion to wheel by semiaxis by decelerator and drives vehicle to travel by dynamic bridge and drive axle, and half
Axle is used for passing to the output torque of differential side gear on driving wheel or hub reduction gear, and semiaxis passes through spline and half axle gear
Wheel is connected, and another end flanges couple with wheel hub, from the torque that differential mechanism outflow comes by semiaxis, wheel hub, is finally transmitted to wheel, institute
It is the strength member that torque is transmitted in power train with semiaxis.This requires semiaxis to have good torsional strength and turned round to transmit
Square, while when automobile heavy-load during weight carried per axle deformation, semiaxis should also have certain deformation adaptability；Semiaxis is working condition
It is more light then better for high-speed rotary part, quality.
Existing semiaxis is solid, heavier mass, the more difficult control of heat treating fault, it is not high to do fatigue strength, it is impossible to
Accomplish that both quality and intensity are taken into account.
The content of the invention
In view of this, it is an object of the present invention to provide a kind of automotive axle semiaxis simple in construction, reasonable in design, easy to use
Structure.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of automotive axle semi-axis structure, including the flange of interconnection and semiaxis bar portion, the semiaxis bar portion and the method
One end that orchid is connected is flange end, and the other end is splined end, wherein the half shafts portion is in hollow form.
Preferably, above-mentioned a kind of automotive axle semi-axis structure, wherein the both ends of the hollow region in the half shafts portion are complete
Running through the semiaxis bar portion entirely, the flange end opening position corresponding with the hollow region of the semiaxis bar portion is provided with plug,
The splined end opening position corresponding with the hollow region of the semiaxis bar portion is provided with inner oil seal.
Preferably, above-mentioned a kind of automotive axle semi-axis structure, wherein the middle control region only one end in the half shafts portion is passed through
The semiaxis bar portion is worn, the other end of semiaxis bar portion is solid.
Preferably, above-mentioned a kind of automotive axle semi-axis structure, wherein the middle control region in the half shafts portion and the method
The semiaxis bar portion is run through in blue relative one end, and in the flange end opening position corresponding with the hollow region of the semiaxis bar portion
Provided with plug, the splined end is solid.
Preferably, above-mentioned a kind of automotive axle semi-axis structure, wherein the middle control region in the half shafts portion and the flower
The semiaxis bar portion is run through in the relative one end in key end, and in the splined end position corresponding with the hollow region of the semiaxis bar portion
Place is provided with inner oil seal, and the flange end is solid.
Compared with prior art, the technology of the present invention effect is mainly reflected in：The technical scheme is improved the structure of semiaxis,
The weight for ensureing to alleviate semiaxis on the premise of transmission moment of torsion is constant simultaneously reaches vehicle loss of weight, saves material, energy-saving consumption-reducing, separately
Outside, quality is lighter, and the anti-twisting property reached when being more convenient, being heat-treated when the semiaxis bar portion of hollow form is processed is than solid semiaxis more
High, hollow semiaxis can improve bending adaptability, while can improve semiaxis fatigue resistance, improve service life；Hollow semiaxis
It is easy to flaw detection, makes finished product semiaxis reliability stronger, it is more secure when used.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail, so that technical solution of the present invention is more
It should be readily appreciated that and grasp.
As shown in Figures 1 to 4, a kind of automotive axle semi-axis structure, the flange 1 and semiaxis bar portion 2 of interconnection, institute are included
It is flange end to state one end that semiaxis bar portion 2 is connected with the flange 1, and the other end is splined end 3, wherein the half shafts portion 2 is in
Hollow form.
" embodiment 1 "
As shown in figure 1, the both ends of the hollow region in wherein described half shafts portion 2 are completely through the semiaxis bar portion 2, it is described
The flange end opening position corresponding with the hollow region of the semiaxis bar portion 2 is provided with plug 5, the splined end 3 and the semiaxis
The opening position that the hollow region of bar portion 2 is corresponding is provided with inner oil seal 4.
" embodiment 2 "
As shown in Fig. 2 the middle control region in wherein described half shafts portion 2 one end relative with the flange 1 is through described half
Axle portion 2, and it is provided with plug 5, the splined end in the flange end opening position corresponding with the hollow region of the semiaxis bar portion 2
