Example Embodiment

[0014] Refer to Figures 2 and 3, the wide-band dynamic shock absorber for automobile rear axle includes a center mounting block 1, a rubber spring ring 2 is sheathed outside the center mounting block 1, and an annular mass block is sheathed outside the rubber spring ring 2 3; Similarly, the outer side of the annular mass 3 is covered with a rubber spring ring 4 and a ring-shaped mass 5, and so on, the outer side of the center mounting block 1 is sequentially covered with rubber spring rings 2, 4 and ring-shaped mass 3 , 5, constitute a multi-degree-of-freedom dynamic damping unit.
[0015] The design of wide-band dynamic shock absorber for automobile rear axle is exactly the same as the design method of general damped multi-degree-of-freedom dynamic shock absorber: according to the frequency range of the automobile rear axle vibration, the amplitude of the vibration force and the allowable amount of vibration, determine The reasonable quality of the annular masses 3 and 5 and the choice of the hardness, damping ratio and optimal frequency ratio of the annular rubber rings 2, 4 can then obtain the design parameters such as the stiffness and damping coefficient of the rubber, which can be targeted The dynamic shock absorber is designed to be suitable for various automobile rear axles. This kind of shock absorber can not only be used for the dynamic damping of automobile rear axle, but also can be applied to various other needs for dynamic damping in a wide frequency band.
