Specific implementation mode
As shown in Figure 1, embodiments of the present invention torque fluctuation absorption plant 1 configuration by internal combustion mechanism at original move
Between machine 2 and speed changer 3, the torque fluctuation of prime mover 2 is absorbed.
Torque fluctuation absorption plant 1 has：1st rotary part 5 is passed via frictional coupling clutches 4 from prime mover 2
Graduating power；With the 2nd rotary part 6, it is adjacent to configuration on the same axis with the 1st rotary part 5.1st rotary part 5 and
2 rotary parts 6 are configured to relative rotation predetermined angular.2nd rotary part 6 is connect with the input shaft 3a of speed changer 3.
In addition, as shown in Fig. 2, the 1st rotary part 5 and the 2nd rotary part 6 are configured to via helical spring 7 into action edge
It transmits.By the helical spring 7, the variation of the torque exported from prime mover 2 is absorbed.The eye icon III of Fig. 2 indicates Fig. 3's
Visual angle.
As shown in figure 3, in the torque fluctuation absorption plant 1 of present embodiment, circumferentially, equally spaced there are four spiral shells for configuration
Revolve spring 7.
Also, as shown in Fig. 4 A, 4B amplification, both adjustment are provided between the 1st rotary part 5 and the 2nd rotary part 6
Between the frictional force adjustment mechanism 8 of frictional force that generates.The frictional force adjustment mechanism 8 is also referred to as slow tiner.The eyes of Fig. 4 A, 4B
Icon VB, VA indicate the visual angle of Fig. 5 B, 5A.
Frictional force adjustment mechanism 8 has：Washer 9 is fixed to integrally rotate with the 1st rotary part 5；Adjust component
10, it is configured between washer 9 and the 1st rotary part 5, enabling with the 1st rotary part 5 freely relative rotation
Certain angle；Elastomeric element 11 is made of the disk spring configured between washer 9 and adjustment component 10.
It is provided with friction member 9a on the face of the side opposite with the 2nd rotary part 6 of washer 9.And in the outer of washer 9
Periphery is provided with multiple tab 9b extended to the 1st rotary part 5.Tab 9b is inserted into respectively is disposed through the 1st by multiple
The fixed part 5a that through hole on rotary part 5 is constituted.Tab 9b engages with fixed part 5a in the circumferential as a result, to washer 9
It is fixed on the 1st rotary part 5.
2nd rotary part 6 has the wheel hub 6a of tubular in rotating center section, i.e. radial inside portion.In the outer of wheel hub 6a
External thread part 6b is provided on circumferential surface.It is discoid to adjust component 10, is provided in center and runs through through what is be inserted into for wheel hub 6a
It is inserted into hole 10a.It is being formed with internal thread on the inner peripheral surface for being inserted into hole 10a, which screws togather with external thread part 6b.
The outer peripheral edge of adjustment component 10 is provided with multiple limited part 10b extended to the 1st rotary part 5.By through hole

Part 10b is inserted into the space of the radially inner side of fixed part 5a.
Limited part 10b is formed as smaller than the circumferential width of fixed part 5a.Also, limited part 10b is relative to fixed part 5a
Circumferential width be set to so that adjustment component 10 can be relative to 5 relative rotation certain angle of the 1st rotary part.
As shown in Figure 5A, torque is become when the vehicle for the torque fluctuation absorption plant 1 for being equipped with present embodiment accelerates
When dynamic absorption plant 1 has input acceleration torque, torsional moment is generated, the 1st rotary part 5 and the 2nd rotary part 6 are with the side of distortion
Formula relatively moves, and positions of the limited part 10b on the left of the attached drawing of fixed part 5a is mobile to attached drawing right side.But limited part 10b with
The relative phase of 2nd rotary part 6 is constant, can continue to the state for maintaining Fig. 4 B.
Conversely, as shown in Figure 5 B, when vehicle deceleration has input deceleration torque to torque fluctuation absorption plant 1, generating
Torsional moment, the 1st rotary part 5 relatively move in a distorted way with the 2nd rotary part 6.Also, limited part 10b is intended to and the 2nd
Rotary part 6 rotates together with, but hangs on fixed part 5a and cannot be rotated together with the 2nd rotary part 6.Therefore, pass through outer spiral shell
For line portion 6b with through screwing togather for hole 10a is inserted into, limited part 10b is moved to the state of Fig. 4 A from the state of Fig. 4 B.As a result, in vehicle
In the state of deceleration, the frictional force between the 1st rotary part 5 and the 2nd rotary part 6 reduces, and can be absorbed by torque fluctuation
Device 1 neatly absorbs the variation of the torque transmitted from the driving wheel of vehicle.In other words, when the 1st rotary part 5 is relative to the 2nd
When rotary part is rotated in deceleration, adjustment component 10 is screwed togather in a manner of being left from washer 9 with external thread part 6b.
When vehicle is transferred to usual state (inertia traveling (used row) state) or acceleration mode from deceleration regime, limited part
10b restores Fig. 4 B with through insertion hole 10a by external thread part 6b by the fixed part 5a pressings of the 1st rotary part 5 by screwing togather
State.
Torque fluctuation absorption plant 1 according to the present embodiment can reduce by the 1st rotating part when inputting deceleration torque
Frictional force (lag) between part 5 and the 2nd rotary part 6.Also, even if change the 1st rotary part 5 and the 2nd rotary part 6 it
Between frictional force, be also able to maintain that the state that is equably abutted within the scope of complete cycle with elastomeric element 11 of adjustment component 10, and energy
Enough prevent the partial wear that part wears only corresponding with abutment portion aggravate as previous product.As a result, according to this embodiment party
The torque fluctuation absorption plant 1 of formula, can inhibit the partial wear of the contact surface of frictional force adjustment mechanism 8, be turned round so as to improve
The durability of square change absorption device 1.
In addition, double-clutch speed changer is shown in the present embodiment, in Fig. 1 as speed changer and is illustrated, but with
The speed changer that the torque fluctuation absorption plant 1 of the present invention connects is without being limited thereto.For example, it can be variable v-belt drive or songs
Shank type contiuously variable transmission, toroidal type stepless speed change device, parallel-axis type multiple-speed gear-box, planetary gear type multi-stage transmission.
In addition, in the present embodiment, be illustrated as elastomeric element using butterfly spring, but the elasticity of the present invention
Component is not limited to disk spring, as long as the elasticity of washer can be pressed between washer and adjustment component to the 2nd rotary part
Component can also use other elastomeric elements.
