Efficient energy absorber

Abstract

The invention discloses an efficient energy absorber. The efficient energy absorber comprises a mounting seat and a rotating shaft arranged on the mounting seat. A sliding bearing is arranged betweenthe rotating shaft and the mounting seat. Connecting rods are arranged on the rotating shaft, and a vibration-absorbing component is mounted on each connecting rod. Each vibration-absorbing componentcomprises an energy-absorbing spring. A counterweight is arranged at the end, close to the rotating shaft, of each energy-absorbing spring, and a fixing block is arranged at the other end of each energy-absorbing spring. An outer thread is machined at the end of each connecting rod. A through hole is formed in each counterweight. The through holes and the energy-absorbing springs penetrate the corresponding connecting rods, and an inner thread matched with the outer thread is machined on each fixing block. Each energy-absorbing spring is a composite spring and comprises a hollow rubber elasticbody and a metal spiral spring body embedded into the rubber elastic body. The efficient energy absorber can effectively absorb the vibration from a frame and has the beneficial effects of being simple in structure, low in manufacturing cost, good in vibration-absorbing effect, convenient to mount and maintain and the like.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a high-efficiency energy absorber. Background technique [0002] With the continuous improvement of car quality, people have more and more comprehensive requirements for car quality, especially the comfort of the car during driving. The car often vibrates due to factors such as the road surface during driving, and the vibration will be transmitted to the various components in the car through the workshop. Long-term vibration will cause the loss of various components in the car, thus affecting the NVH (Noise, Vibration, Harshness; That is, noise, vibration, acoustic roughness) quality. Therefore it is very necessary to install a shock-absorbing structure on the vehicle frame. [0003] Most of the vibration absorbers in the prior art achieve the purpose of energy absorption and vibration reduction through the self-vibration of the resonating block, but the efficiency of energ...

Problems solved by technology

[0003] Most of the vibration absorbers in the prior art achieve the purpose of energy absorption and vibration reduction through the self-vibration of the resonant block, but the efficiency of energy absorption and vibration reduction with a simple structure is low, and the ideal energy absorption and vibration reduction effect cannot be achieved

Although the structure is complex, the shock absorption effect is good, but the manufacturing cost is high, the installation is not convenient, and it is not easy to promote
