Abstract
The present invention provides a kind of localization method of wet clutch spline, can improve shift shock and noise caused by the presence of clutch spline sideshake.The key of this method is to remain that flank is contacted between the spline of restriction clutch housing and steel disc spline.By make be all the time between the spline of clutch housing and steel disc spline flank contact progress it is spacing, it is not in the possibility contacted at the big path of spline, so as to eliminate splined section sideshake, shift shock and noise caused by the presence of spline sideshake are effectively improved, because the reduction of shift shock also improves the service life of parts simultaneously.
Description
Technical field
The present invention relates to automobile gearbox technical field, and in particular to a kind of localization method of wet clutch spline.
Background technology
Current automatic gear-box（Particularly AT and CVT）The internal switching that gear is all carried out using wet clutch structure,
Wet clutch carries out coordinating transmission moment of torsion and rotating speed using the spline between clutch hub, housing and steel disc or friction plate.It is wet
Formula clutch is all to carry out coordinating transmission moment of torsion and rotating speed using the spline between clutch hub, housing and steel disc or friction plate,
Conventional spline species is platform shape tooth.Certain sideshake is all reserved during design between spline to assemble and be easy to the combination of piece group
With separating, but wet clutch is designed without being distinctly claimed the positioning method at spline at present, in fact it could happen that
Situation about being contacted under centrifugal force and Action of Gravity Field at the big path of spline, causes presence of the clutch due to sideshake in engaging process
Cause shift shock and noise.
The content of the invention
The purpose of the present invention is to propose to a kind of localization method of wet clutch spline, it can improve because of clutch spline sideshake
Presence caused by shift shock and noise.
The localization method of the wet clutch spline provided according to the present invention, key is the spline for limiting clutch housing
Remain that flank is contacted between steel disc spline.
By the present invention in that be all the time between the spline of clutch housing and steel disc spline flank contact progress it is spacing, will not
There is the possibility contacted at the big path of spline, so as to eliminate splined section sideshake, effectively improve because of the presence of spline sideshake
Caused shift shock and noise, because the reduction of shift shock also improves the service life of parts simultaneously.
As preferred parameter optimization, limit between the spline of clutch housing and the big footpath of steel disc spline or between path
Gap be simultaneously greater than the maximum shift motion of steel disc radial direction.
Further, above-mentioned preferred parameter optimization is the ginseng of the spline of the spline and steel disc that ensure clutch housing
Number meets formula simultaneously：（Dc1- Dp1）/2>C/sin (θ/2) and（Dc2- Dp2）/2> c/sin(θ/2)；Wherein, Dp1:
The big footpath of steel disc spline, Dp2:Steel disc spline path, Dc1:The big footpath of spline of clutch housing, Dc2：The spline of clutch housing
Path, c:Spline sideshake, h:Steel disc radial direction range, θ：Spline teeth angle, and h=c/sin (θ/2).
Specifically, the h:Steel disc radial direction range refers in clutch operation process because centrifugal force and gravity are made
With the range for causing steel disc to move radially.The θ：Known parameters when spline teeth angle is designed for spline.
Specifically, the spline of the clutch housing and steel disc spline are platform shape tooth spline.The wet clutch
For the wet clutch being adapted to the double clutch gearboxes of stepless gearbox/wet type.
Brief description of the drawings
The structural representation that Fig. 1 coordinates for the clutch housing of the present invention with steel disc.
Fig. 2 is the mplifying structure schematic diagram at Figure 1A.
Embodiment
It is for example involved each to the embodiment of the present invention by the description to embodiment below against accompanying drawing
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of component, construction, each several part etc. are made into one
The detailed description of step.
Such as Fig. 1,2, the localization method of wet clutch spline of the invention, key is the flower for limiting clutch housing 1
Remain that flank is contacted between key and the spline of steel disc 2.As preferred parameter optimization, limit the spline of clutch housing 1 with
Gap between the big footpath of the spline of steel disc 2 or between path is simultaneously greater than the maximum shift motion of the radial direction of steel disc 2.Ensure clutch
The parameter of the spline of device housing 1 and the spline of steel disc 2 meets formula simultaneously：（Dc1- Dp1）/2>C/sin (θ/2) and
（Dc2- Dp2）/2> c/sin(θ/2)；Wherein, Dp1:The big footpath of the spline of steel disc 2, Dp2:The spline path of steel disc 2, Dc1:Clutch
The big footpath of spline of device housing 1, Dc2：The spline path of clutch housing 1, c:Spline sideshake, h:The radial direction range of steel disc 2, θ：
Spline teeth angle, and h=c/sin (θ/2).θ：Known parameters when spline teeth angle is designed for spline.
