Problems solved by technology

For the non-load-bearing frame, the stiffness of the parts and the overall stiffness are mainly considered in the design, and the vibration absorption function of the frame is ignored. When the vehicle moves violently, the frame will vibrate a lot, and resonance will occur in severe cases. Causes huge noise in the cockpit and passenger compartment of the vehicle, affecting the comfort of the vehicle

Abstract

The invention discloses a vibration absorption structure and a vehicle frame therewith for a vehicle. The vibration absorption structure comprises a metal inner pipe, a metal outer pipe and a clump weight, wherein the metal outer pipe is sheathed outside the metal inner pipe, a rubber damping part is arranged between the metal outer pipe and the metal inner pipe, and the clump weight is sheathed on the metal outer pipe. The vibration absorption structure can be fixed on the vehicle frame and is used for absorbing vibration of the vehicle frame so as to improve the NVH (noise, vibration and harshness) performance of the vehicle frame even the whole vehicle, due to the mutual match of the metal inner pipe, the rubber damping part, the metal outer pipe and the clump weight, especially for the combined action of the rubber damping part and the clump weight, the vibration absorption effect is more obvious.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vibration-absorbing structure and a vehicle frame with the vibration-absorbing structure. Background technique [0002] In recent years, my country's automobile industry has developed rapidly. With the improvement of living standards, people's requirements for the NVH performance of automobiles are also increasing. For the non-load-bearing frame, the stiffness of the parts and the overall stiffness are mainly considered in the design, and the vibration absorption function of the frame is ignored. When the vehicle moves violently, the frame will vibrate a lot, and resonance will occur in severe cases. It causes huge noise in the cockpit and passenger compartment of the vehicle, affecting the comfort of the vehicle. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain ext...
