Description

Shock absorbing assembly and vehicle Technical Field The utility model relates to the technical field of vibration absorbing assemblies, in particular to a vibration absorbing assembly and a vehicle. Background Vertical resonance of an automobile axle is one of important reasons for causing vibration in an automobile, and a rear axle vertical vibration absorber is usually designed in the whole automobile development process of the automobile to solve the problem of vibration in the automobile. The mode frequency of the vibration absorber coincides with the vertical pitching mode of the rear axle, so that vibration energy generated when the rear axle resonates is absorbed. In the related technology, in the research and development process of an automobile, the pitching modal frequency of the rear axle is obtained through a simulation or test method, and the vibration absorber is designed according to the frequency characteristic, so that the modal frequency of the vibration absorber cannot be completely matched with the pitching modal frequency of the rear axle due to the problems of simulation or test errors and the like, and at the moment, the frequency value needs to be corrected, and the vibration absorber is reset for test until the vibration absorber is completely matched. The process of repeatedly correcting the iterative vibration absorber is time-consuming and labor-consuming, which leads to the rapid increase of research and development cost, and each new automobile needs to repeatedly research and develop the vibration absorber matched with the new automobile, so that the vibration absorption frequency of the vibration absorber is difficult to adjust, which leads to time and labor consumption, and leads to the rapid increase of research and development cost.
