On extend towards one another.Line 240 intersects each other in any on the Radius positioned at pivot center 115.Here, the company
Line surrounds angle [alpha] with the radius respectively.The degree of the torsion of pendulum mass is herein during pendulum mass 180 is mobile in pendulum mass 175
Size depending on angle [alpha].In addition, the embodiment shown in this is as the embodiment shown in Fig. 2 tops
Operation.The embodiment is preferred in Fig. 1 for the shock absorber 125 in transmitting the device 100 of torque.
Fig. 3 shows situation of the shock absorber 125 of Fig. 2 lower illustration in skew.The neutral position of above-mentioned pendulum mass 180
Put and be shown in broken lines.The center of gravity of unmigrated pendulum mass 180 indicates that the center of gravity of the pendulum mass 180 offset is indicated with s ' with s.
The angle that line 240 surrounds with the Radius of pivot center 115 respectively, is indicated with α.Angle beta is indicated on the edge of pendulum mass 180
Or against the rotation direction of pendulum flange 175 skew during the pendulum mass 180 around its own pivot center 305 turn
It is dynamic.
If pendulum flange 175 in the figure 3 representation rotates in a clockwise direction, for rotation direction, pendulum mass
180 leading edge 310 is located at the right, and back edge 315 is located at the left side.If pendulum mass 180 is in the rotational motion of pendulum flange 175
Moved on direction, in figure 3 be to the right, then its leading edge 310 with its rear rim 315 compared with by more significantly radial direction
It is upper inwardly directed.In the embodiment shown in this, chute guider 205 and 210 is implemented in this wise so that back edge 315
Even diametrically it is oriented to slightly outwards.
Fig. 4 shows the parallel pendulum 400 in skew corresponding with Fig. 3 diagram.Fig. 4 diagram is used for the ladder with Fig. 2 or 3
Shape pendulum 125 is made comparisons.Parallel pendulum 400 equally constructs such as trapezoidal pendulum 125, but difference is, in the neutral position of pendulum mass 180
Extended parallel to each other in putting by the line 240 of pin 225.Generally they prolong also parallel with the Radius of pivot center 115
Stretch.It is seen that different from the situation of the trapezoidal pendulum, pendulum mass 180 is in Fig. 4 on neutral position that it is marked with dotted line
For movement to the right, be not accompanied by the rotation around own axes.
