Part 3 is preferably to vulcanize rubber；Clump weight 4 is provided with the mounting hole 41 of perforation for up-small and down-big symmetrical structure and its upper part.It is interior
The assembly method of casing 2, absorbing part 3 and clump weight 4 is that inner sleeve 2 is made to be engaged with the second through hole 31 with by inner sleeve 2
It is assemblied in absorbing part 3, absorbing part 3 is engaged with mounting hole 41 absorbing part 3 is assemblied in clump weight 4, then by first
5 and second fastener 6 of fastener penetrated successively from the both sides of inner sleeve 2 respectively the connecting hole 11 of respective side in mounting bracket 1 with
And first in through hole 21, so as to which inner sleeve 2, absorbing part 3, clump weight 4 and mounting bracket 1 are fixed together, such as Fig. 4
It is shown, also, the tightening direction of the first fastener 5 is identical with the loosening direction of the second fastener 6.
Fig. 6 a-6c are when being adjusted using above-mentioned bump leveller assembly provided in an embodiment of the present invention to its operating angle
Working state schematic representation, when clump weight 4 is in the setting angle shown in Fig. 6 a, the centerline parallel of clump weight 4 is in perpendicular at this time
Nogata is to the absorbing frequency through the bump leveller assembly under finite element analysis software this setting angle in the vertical direction is 97.9 hertz
Hereby；When clump weight 4 is in the setting angle shown in Fig. 6 b or Fig. 6 c, the central axis of clump weight 4 is in vertical direction at this time,
Through finite element analysis software, the absorbing frequency of bump leveller assembly in the vertical direction under this setting angle is 147.8 hertz,
That is, when the setting angle shown in Fig. 6 a is defined as 0 °, when the setting angle shown in Fig. 6 b and Fig. 6 c is defined as 90 °, install
90 ° of angulation change, frequency adds nearly 50 hertz therewith, since clump weight 4 is up-small and down-big symmetrical structure, axis
Line is parallel to vertical direction, then in theory, by the setting angle of the bump leveller assembly clump weight 4 from 0 ° to 90 ° into
Row adjustment when, corresponding absorbing frequency also will from 97.9 hertz to 147.8 hertz consecutive variations.It therefore, can be at 0 ° to 90 °
In the range of arbitrarily adjust the setting angle of clump weight, i.e., in the setting angle shown in Fig. 6 a and the model of the setting angle shown in Fig. 6 b
It is (or arbitrary in the range of the setting angle shown in Fig. 6 a and the setting angle shown in Fig. 6 c to enclose interior arbitrary selection setting angle
Select setting angle), to obtain corresponding required absorbing frequency, so as to adapt to the vibration damping demand of different vibration parts, pole
The earth improves the scope of application of bump leveller assembly.
