Description
Technical field
The utility model is related to auto parts and components, specifically a kind of aluminium driving shaft.
Background technology
Currently, the major part of commercial car transmission shaft uses 45 or 45Cr materials, weight is larger, as vehicle lightweight is wanted
It asks higher and higher, needs to realize lightweight using new material, aluminum alloy materials density is small, and intensity is higher, is a good choosing
It selects, therefore aluminium driving shaft foreground is very wide.
Application number 201420852655.7, the utility model is related to a kind of aluminum alloy drivings by applying date 2014.12.29
Axis, including slip yoke, flanged yoke, two be in symmetrical universal joint and weld yoke, the weld yoke use aluminium bar forging forming,
Two weld yokes are connected with two universal joints respectively, and one of universal joint is connected with slip yoke, which connects with gearbox
It connects, another universal joint is connected with flanged yoke, which connect with rear axle；The transmission shaft further includes central siphon, the central siphon
Using the tubing of cold drawn forming, the central siphon is located between two weld yokes being symmetric, and by friction welding at
Type is integrated；The weld yoke and central siphon is all made of 6061-T6 aluminum alloy materials；The utility model have it is simple in structure,
Weight mitigates 40-60% on year-on-year basis, and installation is simple and convenient, eliminates intermediate support structure, avoids caused by intermediate support
The characteristics of Vehicular vibration noise.
Although solving the problems, such as weight in above-mentioned patent, central siphon is a monolithic construction, passes through slip yoke solution
Certainly the problem of vibration, when central siphon will produce stress and torsion to automobile in motion, it is easy to damage transmission shaft, so having
Defect.
Invention content
In order to solve automobile, central siphon will produce stress and torsion to the utility model in motion, while also reduce vehicle weight
Amount reduces oil consumption, promotes vehicle NVH performances, and spy proposes a kind of aluminium driving shaft.
The technical solution of the utility model is that a kind of aluminium driving shaft, including aluminium alloy central siphon, feature exist thus
In：One end of aluminium alloy central siphon is equipped with aluminium alloy universal-joint fork, and the other end is equipped with aluminium alloy spline housing, forms integral structure；
Wherein aluminium alloy universal-joint fork is connected by cross axle two with flange york two, and aluminium alloy spline housing matches merga pass with slip shaft yoke
Cross axle one is connected with flange york one.
Further improve is：Aluminium alloy central siphon, aluminium alloy universal-joint fork and the aluminium alloy spline housing is all made of
6061 T6 of aluminum alloy materials is made；It is one that aluminium alloy central siphon, which is coupled with universal-joint fork and aluminium alloy spline housing by welding manner,
Body.
Further improve is：The slip shaft yoke is externally provided with sheath, by the company of aluminium alloy spline housing and slip shaft yoke
The place of connecing covers on inside sheath.
Advantageous effect：
One end of aluminium alloy central siphon is equipped with aluminium alloy universal-joint fork in the utility model, and the other end is equipped with aluminium alloy spline
Set forms integral structure so that entire transmission shaft mitigates weight, merges simultaneously because aluminium alloy spline housing is matched with slip shaft yoke
It is connected with flange york one by cross axle one, solving automobile, central siphon will produce stress and torsion in motion, solve central siphon
Vibration, eliminate vibration within the shortest time.
Aluminium alloy central siphon, aluminium alloy universal-joint fork and aluminium alloy spline housing are all made of 6061-T6 aluminum alloy materials, density
It is the one third or so of steel density (7.8x10-6kg/mm3) for 2.7x10-6kg/mm3, under equal volume, weight
It is 30% or so of steel part.
Aluminium alloy central siphon is connected as one with universal-joint fork and aluminium alloy spline housing by welding manner.Monolithic construction is not
It is only easy for installation, while stress, torsion and vibration problem when in use is solved.
The setting of sheath can be dust-proof.
The utility model has reached loss of weight, has subtracted assembly, subtracts part, and one replaces two, and weight reduces by 20% ~ 60%；
One replaces two, solves the vehicle vibration problem caused by intermediate support；Promote vehicle NVH performances；It reduces and turns
Dynamic inertia；Reduce oil consumption.
Description of the drawings
Fig. 1 is the front sectional view of the utility model.
1 is aluminium alloy central siphon in figure, and 2 be aluminium alloy universal-joint fork, and 3 be aluminium alloy spline housing, and 4 be cross axle two, and 5 be prominent
