Embodiment Construction

[0018] Such as figure 2 , 3 The suspension vibration-absorbing structure (vibration absorber) shown includes a mounting bolt 1 and a mass block 2, that is, the mass block 2 used to adjust the vibration frequency is directly fixed on the mounting bolt 1, and the mounting bolt 1 includes a bolt head and a bolt column, and the bolt column There is an external thread for fixing, and the mounting point of the suspension bracket can be used without re-drilling holes and adding connecting bolts

[0019] In order to ensure that the mass block 2 is fixed reliably, a metal bushing 3 is provided on the bolt column near the end of the bolt head of the mounting bolt 1. The height of the metal bushing 3 is larger than the flat mass block 2, and the mass block 2 is fixed on the metal bushing 3. In order to avoid noise caused by collision between the two, a rubber washer 4 is provided between the metal bush 3 and the mass block 2, which can also ensure reliable fixing.

Abstract

The invention discloses a suspended vibration absorbing structure. The suspended vibration absorbing structure comprises a mounting bolt and a mass block which is fixed on a bolt bar of one end, which is close to a bolt head, of the mounting bolt. The suspended vibration absorbing structure has the advantages that a vibration absorber mounting mode is simplified, the suspended vibration absorbing structure is fixed by bolts of the original suspended support, and the suspended support is not required to be changed, and is low in cost and convenient to mount.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a suspension vibration absorbing structure. Background technique [0002] At present, vibration absorbers in the NVH field of automobiles are mostly used for passive vibration and noise reduction, and are generally aimed at vibration and noise at specific frequencies. figure 1 The middle is a schematic diagram of the vibration absorber in the prior art. The installation method is fixed by multiple bolts. If this method is used for the suspension bracket, the installation surface of the suspension bracket needs to be washed and drilled, and the workload will increase and the cost will be higher. high. [0003] In addition, according to the noise test data in the car at 1900rpm (sixth order) and 2900rpm (fourth order), there is roaring in the front row of the car. From the vibration test data of the right suspension body side bracket, it is found that the right suspension brac...
