Abstract
The utility model relates to a full-floating type hollow half shaft, belonging to the field of manufacturing automotive transmission devices. The full-floating type hollow half shaft comprises a flange plate and a half shaft, wherein the half shaft is a hollow half shaft; one end of the hollow half shaft is connected with the flange plate in a friction welding way to form an integrated structure; and the inner hole of the hollow half shaft is not more than 0.4 times the outer diameter of the hollow half shaft. After the full-floating type hollow half shaft is realized, single half shaft can be reduced in weight by 8-12%, so that the lightweight design of finished automotives is realized, and good energy-saving and emission-reducing effects of automotives can be achieved.
Description
Technical field
The utility model relates to a kind of full-floating hollow half axle, belongs to automotive trannsmission system and makes the field.
Background technology
The radical function of semiaxis is that moment of torsion is passed to powered vehicle by diff, and according to the mounting means of wheel hub, the structural shape of automobile axle shaft is divided into three kinds: full-floating, semi-floating and 3/4ths floating.At present traditional fully floating axle all is the solid axle that adopts, and makes complete vehicle weight increase, and it is bad to fall heavy effect, increases manufacturing cost, is unfavorable for the energy-saving and emission-reduction of vehicle.
The utility model content
The utility model technical matters to be solved is, overcomes the shortcoming of prior art, and a kind of full-floating hollow half axle is provided, and satisfying under original performance condition, can make car load realize the design goal of lightweight and car load energy-saving and emission-reduction.
In order to solve above technical matters, the utility model provides a kind of full-floating hollow half axle, comprises flange and semiaxis, and said semiaxis is a hollow half axle, and said hollow half axle one end and said flange constitute integral structure in succession through friction welding.
The technical scheme that the utility model further limits is: aforesaid full-floating hollow half axle, the endoporus of said hollow half axle is smaller or equal to 0.4 times said hollow half axle external diameter.
The beneficial effect of the utility model is: after the utility model was realized the full-floating hollow half axle, single semiaxis can alleviate the 8%--12% of former weight, realized the car load light-weight design, made automobile well play the effect of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment 1
A kind of full-floating hollow half axle that present embodiment provides; Structure is as shown in Figure 1, comprises flange and semiaxis, and semiaxis is a hollow half axle; Said hollow half axle one end and said flange constitute integral structure in succession through friction welding, remove the overlap that welding stays after having welded again; The hollow half axle external diameter that the endoporus of hollow half axle equals 0.4 times.
Usually in design, often make the margin of strength of semiaxis be lower than the margin of strength of other transmitting torque parts of drive axle, make semiaxis play " wire fuse " in the similar circuit.Usually safety factor
is in the 1.3--1.6 scope.Will consider that also the semiaxis surface needs mid frequency induction hardening, the induction hardening hardened-depth is generally 1/4～1/3 of bar portion radius; So the endoporus of hollow half axle is selected 0.4 times external diameter for use, i.e. d=0.4D, Theoretical Calculation is following:
is the semiaxis material yield limit;
The torsional shear stress of half shafts portion
;
Hollow shaft? /?
solid shaft = 0.9744;
Can draw
hollow shaft=0.9744 ns solid axle;
Can judge that from computation structure the endoporus of hollow half axle is selected the external diameter less than 0.4 times for use, promptly <under the 0.4D condition, how many actual safety factors do not reduce to d, can satisfy operating needs.
The technological process that the full-floating hollow half axle of present embodiment adopts divides three steps: 1, hollow central siphon round steel--the spline shank of upsetting in advance; 2, round steel--preparatory rammer dish portion; 3, with carrying out friction welding after 1,2 moulding, forming whole,--------modified----------Flange Plane is ground in mid frequency induction hardening--boring--to half finish turning to ball blast to mill spline in alignment in prtreatment to carry out normalizing to remove overlap.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. the full-floating hollow half axle comprises flange and semiaxis, it is characterized in that: said semiaxis is a hollow half axle, and said hollow half axle one end and said flange constitute integral structure in succession through friction welding.
2. full-floating hollow half axle according to claim 1 is characterized in that: the endoporus of said hollow half axle is smaller or equal to 0.4 times said hollow half axle external diameter.
