In addition, in the inner peripheral portion of the second daughter board 22, elastic baffle ring 26 is provided with transmission side.Using the elastic baffle ring 26,
Prevent pre- damper unit 10 from being come off towards transmission side.
[action]
When friction facing 14 towards engine side flywheel pressing when, the torque from engine via clutch disc 2 to from
Clutch plate 3 and baffle plate 4 are transmitted.The torque is according to the flange 5 of torsionspring 8 → the first or second 6 → output hub of flange 7
Route is transmitted.In addition, being transferred to the torque of baffle plate 4 according to the route of baffle plate 4 → 10 → output hub of pre- damper unit 7 to change
The axle output of fast device side.
Specifically, in idling etc., the small twisting vibration of angle of displacement is transmitted from engine side to clutch plate assembly 1
When, the twisting vibration is not twisted spring 8 and hysteresis torque generation mechanism 9 absorbs and transmitted to pre- damper unit 10.So
Afterwards, in pre- damper unit 10, outer circumferential side pre torqued spring 23 and the tandem working of inner circumferential side pre torqued spring 24, in baffle plate 4
And first produce between daughter board 21 and the second daughter board 22 and rotate against.Here, producing less as caused by the slip of each component
Hysteresis torque (in more detail, is provided with hysteresis torque generation mechanism) in the outer circumferential side of the output hub 7 of main damper unit, position
The small twisting vibration in angle is moved to be decayed.
Here, be only that inner circumferential side pre torqued spring 24 stretches in the case where twisting vibration is small, or inner circumferential side pre torqued
Spring 24 and outer circumferential side pre torqued spring 23 are flexible.Then, when twisting vibration further increases and inner circumferential side pre torqued spring
During 24 elastic deformation increase, the engaging protrusion 22d of the second daughter board 22 and the hole 21c of the arc-shaped of the first daughter board 21 end face are supported
Connect.Thus, hereafter, the further elastic deformation of outer circumferential side pre torqued spring 23 is only made.
It is such more than to act, in pre- damper unit 10, can realize torque characteristic wide angle and two grades
Change.
Next, it is following, enter when the twisting vibration with bigger angle of displacement is transferred to clutch plate assembly 1
Row explanation.
In such a case, in the case where clutch plate 3 and baffle plate 4 rotate towards-R directions, the first flange 5 can
Rotated against with two plate 3,4, but the second flange 6 is prohibited to rotate against with two plates 3,4 and integratedly rotated.Thus, when two
When court-the R of plate 3,4 directions rotate, torque is transmitted from two plates 3,4 to pre- damper unit 10, and via torsionspring 8 to first
Flange 5 is transmitted, and is further transmitted to output hub 7.
Now, by the work of such pre- damper unit 10, the only relative rotation of the flange 5 of output hub 7 and first
Turn the windup-degree suitable with the clearance G 1 shown in Fig. 4.Then, as the first tooth 7b and the breach of the first flange 5 of output hub 7
When the end face in 5d+R directions is abutted, output hub 7 integratedly rotates with the first flange 5.Afterwards, the elastic deformation of torsionspring 8,
Two plates 3,4 and the second flange 6 rotate against the angle suitable with clearance G 2 with the first flange 5 and output hub 7.Then,
First tooth 7b of output hub 7 is abutted with the end face in the breach 6d of the second flange 6+R directions, and rotating against for they is banned
Only.That is, the breach 6d of the second flange 6 end face as limiter function.
In addition, in the case where clutch plate 3 and baffle plate 4 rotate towards+R directions, with more than on the contrary, the first flange 5 with
Clutch plate 3 and rotating against for baffle plate 4 are prohibited, and the second flange 6 can be rotated against.Thus, when pre- damper unit
10 work and the first tooth 7b of output hub 7 with the end face in the breach 6d of the second flange 6-R directions when abutting, output hub 7
Integratedly rotated with the second flange 6.Afterwards, the elastic deformation of torsionspring 8, two plates 3,4 and the first flange 5 and the second flange 6
And output hub 7 rotates against the angle suitable with clearance G 2.Then, the first tooth 7b of output hub 7 and the 5th flange 5
The end face in breach 5d+R directions is abutted, and rotating against for they is prohibited.That is, the breach 5d of the first flange 5 end face conduct
Limiter and function.
