Engaging tooth is fixedly connected with the multiple inner attrition piece.
The outer ring surface of second axle sleeve 2, which is evenly equipped with, to be engaged with the inner ring surface of multi-disc wet clutch engagement disk component 3
The mesh tooth face 6 of tooth engagement.
In power transmission process, when the multi-disc wet clutch engages, the second axle sleeve 2 is set to produce axis by motor driving
To movement, when inner attrition piece is in half-clutch state with outside friction disc, due to the drive of outside friction disc, inner attrition piece starts to turn
Dynamic, the inner attrition piece drives the second axle sleeve 2 to rotate again so that the second axle sleeve 2 produces axial after being connected with 1 wedging of the first axle sleeve
Reinforcement, axial reinforcement superimposed motor driving force described at this time drive the second axle sleeve 2 to continue axial movement and are finally completed inner attrition piece
With being fully engaged for outside friction disc, power transmission is realized.
The outer sheath of the multiple inner attrition piece and multiple outside friction discs is equipped with bell housing 9, and the bell housing 9 has
Mesh tooth face to be engaged with 3 outer ring surface engaging tooth of multi-disc wet clutch engagement disk component, consolidate by the outer ring surface engaging tooth
Surely the multiple outside friction disc is connected.
Second axle sleeve 2 is set on the first axle sleeve 1, the outer ring surface of first axle sleeve 1 and the second axle sleeve 2 it is interior
Anchor ring is smooth cylindrical surface, and 1 and second axle sleeve 2 of the first axle sleeve opposite can slide.
First axle sleeve 1 and the structure of 2 wedgeable of the second axle sleeve connection are：The front side of second axle sleeve 2 is equipped with some
A groove 7, preferably 3 grooves, the front side mapping of the first axle sleeve 1 are convexly equipped with several voussoirs 8, pass through matching somebody with somebody for voussoir 8 and groove 7
Closing connection makes the first axle sleeve 1 be connected with 2 wedging of the second axle sleeve.
There is inclined contact surface in circumferential one end of the first axle sleeve 1, the groove 7 has and the wedge on the voussoir 8
The inclined contact surface of block 8 corresponds to matched inclined contact surface 11, the inclined contact surface (inclined-plane) of the voussoir and the groove
Inclined contact surface 11 (inclined-plane) contact squeeze when so that voussoir 8 and groove 7 produce opposite shaft orientation power, due to 1 axis of the first axle sleeve
To fixation, therefore the second axle sleeve 2 is promoted by this axial force, is moved axially backwards to the first axle sleeve.
The voussoir 8 is rectangular prismatoid, and the groove 7 is corresponding to the similar matched right-angled trapezium of 8 shape of voussoir
Groove.
The structure that it is in " work " font with cross section that first axle sleeve 1, which is, including outer ring body and inner ring body, outer ring body and inner ring
Body is connected by more intermediate annular body, forms the first axle sleeve 1 of dies, and described outer ring body one end is convexly equipped with the voussoir
8, the inner ring surface of the inner ring body has engaging tooth anchor ring 5.
Inner sleeve 4 is fixedly connected with the inner end platen 10 of the multiple inner attrition piece, and work bearing extrudes the second axle sleeve 2
Afterwards, the second axle sleeve 2 promotes the multiple inner attrition piece to be axially moved from the inside end in the outer end of the multiple inner attrition piece, to
Inner end platen 10 extrudes so that clutch gradually combines.
The course of work of the present invention：When needing clutch to engage, working shaft honours the second axle sleeve 2 and applies an axial force
Move axially the second axle sleeve 2, such inner attrition piece and outside friction disc are in half-clutch engagement state, and inner attrition piece, which rotates, to be driven
Second axle sleeve 2 rotates, and opposite slippage is produced between the second axle sleeve 2 and the first axle sleeve 1, increases axial pressing force by inclined wedge,
Further to 2 reinforcement of the second axle sleeve, complete to be fully engaged inner attrition piece and outside friction disc.
During throw-out-of clutch, work bearing reverse movement no longer reinforces, and driving force is reduced, hereafter, in first axle
Cover 1 rotating speed more than under 2 state of the second axle sleeve, the inclined wedge of the first axle sleeve 1 no longer to the second axle sleeve 2 groove 7 inclined-plane applying power,
The groove inclined-plane no longer stress of second axle sleeve 2, then the second axle sleeve 2 slip set back, and interior outside friction disc is automatically separated.
The multiple inner attrition piece and/or multiple outside friction discs are steel disc or nylon6 chips or other materials, it is the multiple in
Outside friction disc can be compressed in the axial direction, realized and be frictionally engaged.
The multiple inner attrition piece and/or the multiple outside friction disc are plate in a circumferential direction or with recessed
Convex textured profile, it is elastically deformable or flexible in a circumferential direction to be preferably designed to be allowed to.Exist in friction plate
In the case of there is Z-Correct bump mapping Z-correct shape profile on circumferencial direction, there is provided more than at least three equally distributed convex shaped parts in the circumferential
And more than at least three respective numbers concavity, convex shaped part and concavity be circumferentially alternately arranged, preferably four to eight pairs.It is preferred that
Z-Correct bump mapping Z-correct shape profile is mathematic curve profile.Distance is 0~5mm to the peak and concavity minimum point of convex shaped part vertically,
It is preferred that 2mm, the preferable moment of torsion for being so provided with the clutch for being beneficial to obtain multiple-piece of Z-Correct bump mapping Z-correct shape profile transmits unanimously
Property and avoid any axial direction that may be present from rocking and compensated to axial error, improve clutch engagement stability.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, should all be covered by within protection scope of the present invention.
