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 ...

Abstract

A automobile rear axle wide band power vibration-damper mounted on the rear axle for reducing the vibration of the rear axle includes a central mounting piece, a mounting hole in the middle of or at the bottom of the central mounting piece, at least one layer of rubber spring turns on the outer-ring of the central mounting piece and corresponding mass pieces fixed on the cylindrical surface of each layer of rubber spring turns.

Description

Technical field: [0001] The invention relates to a wide-band dynamic shock absorber for the rear axle of an automobile, which is used for being installed on the rear axle of the automobile to reduce the vibration of the rear axle, and can also be applied to various other fields requiring wide-band dynamic vibration reduction. Background technique: [0002] In order to reduce the automobile vibration caused by the dynamic unbalanced force generated when the main transmission (differential) of the rear axle of the automobile rotates, one or two dynamic shock absorbers are usually installed at or near the differential casing to reduce the vibration. From the structural point of view, the dynamic shock absorber is mainly composed of elastic elements and mass elements, in which the elastic elements provide restoring force for the vibration of the mass elements. When the dynamic shock absorber is working, it can convert the vibration of the rear axle into the vibration of the qual...
