[movement]
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 4 transmit.The torque is according to 8 → the first flange 5 of torsionspring or second 6 → output hub of flange 7
Route transmitting.In addition, being transferred to the torque of baffle 4 according to baffle 4 → 10 → output hub of pre- damper unit 7 route to change
The axis of fast device side exports.
Specifically, in idling etc., the small twisting vibration of angle of displacement is transmitted from engine side to clutch plate assembly 1
When, which is not twisted spring 8 and hysteresis torque generation mechanism 9 absorbs, and transmits to pre- damper unit 10.So
Afterwards, in pre- damper unit 10, peripheral side pre torqued spring 23 and 24 tandem working of inner circumferential side pre torqued spring, in baffle 4
Relative rotation is generated between the first daughter board 21 and the second daughter board 22.Here, generating lesser caused by the sliding as each component
Hysteresis torque (in more detail, is equipped with hysteresis torque generation mechanism in the peripheral side of the output hub 7 of main damper unit), position
The small twisting vibration in angle is moved to be decayed.
It is only that inner circumferential side pre torqued spring 24 is flexible or inner circumferential side pre torqued here, in the case where twisting vibration is small
Spring 24 and peripheral side pre torqued spring 23 are flexible.Then, when twisting vibration further increases and inner circumferential side pre torqued spring
When 24 flexible deformation increases, the engaging protrusion 22d of the second daughter board 22 and the end face of the hole 21c of the arc-shaped of the first daughter board 21 are supported
It connects.As a result, hereafter, only make the further flexible deformation of peripheral side pre torqued spring 23.
By above such movement, in pre- damper unit 10, the wide angle and second level of torque characteristic can be realized
Change.
Next, hereinafter, for have the case where twisting vibration of bigger angle of displacement is transferred to clutch plate assembly 1 into
Row explanation.
In such a case, in the case where clutch plate 3 and baffle 4 are rotated towards the direction-R, the first flange 5 can
With above-mentioned two plate 3,4 relative rotation, but the second flange 6 be prohibited with two plates 3,4 relative rotation and integrally rotate.As a result, when
When two plate 3,4 is rotated towards the direction-R, torque is transmitted from two plates 3,4 to pre- damper unit 10, and via torsionspring 8 to the
The transmitting of one flange 5, is further transmitted to output hub 7.
At this point, by the work of such pre- damper unit 10, output hub 7 and the only opposite rotation of the first flange 5
Turn and the comparable windup-degree of clearance G 1 shown in Fig. 4.Then, when the notch of the first tooth 7b of output hub 7 and the first flange 5
When the end face in the direction+R of 5d abuts, output hub 7 is integrally rotated with the first flange 5.Later, 8 flexible deformation of torsionspring,
When two plates 3,4 and the second flange 6 and the first flange 5 and 7 relative rotation of output hub and 2 comparable angle of clearance G, output
First tooth 7b of wheel hub 7 is abutted with the end face in the direction+R of the notch 6d of the second flange 6, their relative rotation is prohibited.That is,
The end face of the notch 6d of second flange 6 is functioned as limiter.
In addition, in the case where clutch plate 3 and baffle 4 are rotated towards the direction+R, with it is above on the contrary, the first flange 5 with
The relative rotation of clutch plate 3 and baffle 4 is prohibited, and the second flange 6 being capable of relative rotation.As a result, when pre- damper unit
10 work and the first tooth 7b of output hub 7 with the end face in the direction-R of the notch 6d of the second flange 6 when abutting, output hub 7
It is integrally rotated with the second flange 6.Later, 8 flexible deformation of torsionspring, two plates 3,4 and the first flange 5 and the second flange 6
And when 7 relative rotation of output hub and 2 comparable angle of clearance G, the first tooth 7b of output hub 7 and lacking for the first flange 5
The end face in the direction+R of mouth 5d abuts, their relative rotation is prohibited.That is, the end face of the notch 5d of the first flange 5 is as limit
Position device and function.
[feature]
(1) position-limit mechanism is realized using output hub 7 and two flanges 5,6.It therefore, there is no need to as previous device
Position-limit mechanism including the setting of flange outer periphery portion is comprising spacer pin.It is true thereby, it is possible to be used to be arranged the space of torsionspring
Protect wider, high torque (HT) and wide angle easy to accomplish.
(2) due to being formed by the end face that spring supporting portion 5c, 6c support torsionspring 8, energy using each flange 5,6
It is enough used in and each flange 5,6 is forbidden to function relative to the plate 3 of input side, the structure of 4 relative rotation as spring leaf.
(3) since two flanges 5,6 are set as same shape, it is able to suppress manufacturing cost.
(4) pre- damper unit 10 has the peripheral side pre torqued spring 23 and inner circumferential side pre torqued spring of tandem working
24.Therefore, it can be realized the wide angle in pre- damper unit 10.
(5) a part of baffle 4 is functioned as the input side plate of pre- damper unit 10.Therefore, with it is previous
Pre- damper unit compare without input side plate, axial dimension can be shortened compared with previous device.
(6) it using the first daughter board 21 of connection peripheral side pre torqued spring 23 and inner circumferential side pre torqued spring 24, carries out outer
The support of side pre torqued spring 23 and inner circumferential side pre torqued spring 24.Therefore, it can be realized using less number of components
Wide angle.
(7) rotation angle range of the second daughter board 22 is limited using the first daughter board 21.Therefore, in pre- damper unit 10
In can be realized the second level of torque characteristic.
[other embodiment]
The present invention is not limited to above such embodiment, can not depart from the scope of the present invention carry out various modifications or
Amendment.
(a) structure for fixing two flanges relative to the plate of input side is not limited to the embodiment.For example, it is also possible to structure
Protrusion is set as in each flange, the notch sections etc. different from the first opening that the plate that protrusion is inserted in input side is formed.
(b) in said embodiment, two flanges are set as identical shape, but can also be set to different shapes
Shape.
Industrial applicibility
In the present invention, previous flange is divided into the flange of side's rotary side and the flange of another party's rotary side, benefit
