The invention provides a rear axle vibration absorption assembly, a vehicle and a vibration absorption assembly frequency adjusting method and device. The rear axle vibration absorption assembly comprises a rear axle structure, an elastic connecting part and a balance weight part which are sequentially arranged in a stacked mode, an adjusting hole is formed in the elastic connecting part, and the adjusting hole is used for adjusting the rigidity of the elastic connecting part. Therefore, according to different vehicle types, by adjusting the rigidity of the elastic connecting part and/or changing the mass of the balance weight part, the frequency of the rear axle vibration absorption assembly coincides with the modal frequency of the vehicle rear axle, so that energy generated by resonance is counteracted, and the better damping effect is achieved.

    本发明提供一种后桥吸振组件、车辆、吸振组件频率调整方法及装置,后桥吸振组件包括依次层叠设置的后桥结构、弹性连接部和配重部,弹性连接部上设有调节孔,调节孔用于调整弹性连接部的刚度。从而,针对不同的车型通过调整弹性连接部的刚度和/或改变配重部的质量,使得后桥吸振组件的频率与车辆后桥的模态频率重合,以抵消共振产生的能量,达到更佳的减震的效果。
