In the present embodiment, the center of hub flange 4 is formed with hub flange mounting hole, and the use of hub flange 4
The multiple internal splines protruded towards radially inner side are formed in the medial surface for forming hub flange mounting hole.
In the present embodiment, Plate hub core 10B is installed on hub flange mounting hole.As shown in Figure 3b, Plate hub core 10B includes
Plate hub core main body 101 with cylindrical shape and the radial protrusion portion protruded from the Plate hub core main body 101 towards radial outside
102.The multiple external tooths 104 protruded towards radial outside are formed in the lateral surface in radial protrusion portion 102, protrude towards radial outside
Multiple external splines 103 be formed in Plate hub core main body 101 the other parts other than radial protrusion portion 102 radial outside
Face.
Specifically, (interval refers at interval of adjacent two external splines 103 in multiple external splines 103 on circumferential C
The interval on circumferential C between the center of two external splines 103, similarly hereinafter) be greater than adjacent two in multiple external tooths 104 outer
Tooth 104 at the interval (interval refers to the interval on circumferential C between the center of two external tooths 104, similarly hereinafter) on circumferential C,
In specific example shown in the figure, adjacent two external splines 103 in multiple external splines 103 on circumferential C between be divided into
Substantially twice of interval of adjacent two external tooth 104 on circumferential C in multiple external tooths 104.Further, multiple external tooths
The external tooth 104 of half quantity in 104 is aligned on axial A respectively with corresponding external splines 103.That is, multiple external tooths
It is just aligned on axial A with a corresponding external splines 103 in 104 every an external tooth 104.
In the present embodiment, frictional damping control panel 6B is connected to hub flange 4, frictional damping control from axial side
Disk 6B can be rotated relative to hub flange 4.As shown in Figure 3c, the center of the main body 61 of frictional damping control panel 6B is formed with confession
The frictional damping control panel mounting hole of Plate hub core 10B installation.The frictional damping control panel mounting hole of frictional damping control panel 6B
Periphery is formed with the axial projection portion 62 towards axial side protrusion, and support plate 7 and primary diaphragm spring 8 are abutted from radial outside
In axial projection portion 62.In this way, frictional damping control panel 6B is limited on axial A and radial direction R, but can be in circumferential C
Upper rotation.Further, the medial surface for being used to form frictional damping control panel mounting hole of frictional damping control panel 6B is formed with
The multiple internal tooths 63 protruded towards radially inner side, a part of each internal tooth 63 are formed in the radial direction in the axial projection portion 62
Inner surface.
As shown in fig. 4 a, in the case where friction clutch is in the neutral position not worked, circumferential the one of each external tooth 104
Central angle corresponding to range between side end face and another side end face of circumferential direction of corresponding each internal tooth 63 is the first predetermined angular
(central angle K).In the case where clutch is in the neutral position not worked, a circumferential side end face for each external splines 103 with it is right
Central angle corresponding to range between another side end face of the circumferential direction for each internal spline answered is that the first predetermined angular and second are predetermined
The sum of angle.It is arranged in this way, in Plate hub core 10B relative to frictional damping control panel 6B and hub flange 4 towards circumferential one
After side rotates the first predetermined angular, each external tooth 104 is abutted with corresponding internal tooth 63 respectively, then in Plate hub core 10B and friction
Damping control disk 6B relative to hub flange 4 towards circumferential side rotate the second predetermined angular after, each external splines 103 respectively with
Corresponding internal spline abuts, so that hub flange 4, frictional damping control panel 6B and Plate hub core 10B are rotated together.
Further, in friction clutch of the invention, with the first predetermined angular is 7 ° and the second predetermined angular is 0 °
For the effect of above structure is illustrated.
When Plate hub core 10B relative to friction plate 1 towards circumferential side from 0 ° to 7 ° during rotation, it is according to the present invention
The working condition of friction clutch is as the working condition of friction clutch in the prior art.
After Plate hub core 10B turns to 7 ° towards circumferential side relative to friction plate 1, as shown in Figure 4 b, Plate hub core 10B
External tooth 104 abutted with the internal tooth 63 of frictional damping control panel 6B.
When Plate hub core 10B relative to friction plate 1 towards circumferential side from 7 ° to 8 ° during rotation, Plate hub core 10B and
Frictional damping control panel 6B due to external tooth 104 and internal tooth 63 abutting and turn together relative to hub flange 4 towards circumferential side
It is dynamic.At this point, due to frictional damping control panel 6B relative to hub flange 4 towards circumferential side rotate, friction control can be passed through
Disk 6B realizes the sluggish torque roughly the same with total sluggish torque in the main damping stage of the clutch of the prior art in advance.
In this way, after Plate hub core 10B turns to 8 ° towards circumferential side relative to friction plate 1, the outer flower of Plate hub core 10B
Key 103 is abutted with the internal spline of hub flange 4, at this moment due to having formd higher sluggish torque in previous stage,
The external splines 103 of Plate hub core 10B will not generate ear-piercing beat noise during abutting with the internal spline of hub flange 4.
In other words, by using above-mentioned technical solution, after torque is transmitted to clutch driven plate from friction plate,
Firstly, hub flange 4 is rotated towards the circumferential other side relative to Plate hub core 10B together with frictional damping control panel 6B
After first predetermined angular (i.e. Plate hub core 10B rotates the first predetermined angular towards circumferential side relative to friction plate 1), friction resistance
The internal tooth 63 of Buddhist nun's control panel 6B is abutted with the external tooth 104 of Plate hub core 10B；
Then, hub flange 4 continues to rotate towards the circumferential other side relative to Plate hub core 10B, the control of frictional damping at this time
Disk 6B is rotated together with Plate hub core 10B, and friction is produced between frictional damping control panel 6B and hub flange 4 and support plate 7
Damping torque, so that playing buffer function to the rotation of Plate hub core 10B；
Finally, when hub flange 4 continues to rotate the second predetermined angular (i.e. relative to Plate hub core 10B towards the circumferential other side
Plate hub core 10B rotates the second predetermined angular towards circumferential side relative to friction plate 1) after, the internal spline and disk of hub flange 4
The external splines 103 of hub core 10B abuts, and the internal spline of hub flange 4 and the outer flower of Plate hub core 10B are made due to above-mentioned buffer function
Beat noise when key 103 abuts collision reduces, so that ear-piercing beat noise will not be generated.
The specific technical solution of the present invention is set forth in above specific embodiment, but is also needed
It is noted that
1. above-mentioned first predetermined angular and the second predetermined angular are not limited to the specific number illustrated in above-mentioned specific embodiment
Value, but other numerical value appropriate can be used.In addition, in the present invention, angled each mean intercepted along radial R
