AI Technical Summary

Technical Problem

Existing steering wheel damping structures suffer from poor wide-frequency damping performance, easy structural failure, weak adaptability, and high cost due to structural complexity.

Method used

The steering wheel damping device uses a built-in closed storage cavity filled with metal damping particles. Through the free collision, friction and shearing action of the metal damping particles in the closed storage cavity, it achieves wide-frequency damping. It is integrated into the steering wheel frame by casting or machining, avoiding external damping components.

Benefits of technology

It achieves wide-frequency and efficient shock absorption, improves driving comfort, enhances versatility and durability, reduces production and maintenance costs, is compatible with a variety of vehicle models, and does not change the appearance of the steering wheel.

Abstract

The present application relates to steering wheel technical field, provide a kind of steering wheel damping device, steering wheel skeleton is built-in with multiple damping mechanisms, multiple damping mechanisms are distributed in steering wheel skeleton;The damping mechanism includes the closed storage cavity being opened in steering wheel skeleton, and closed storage cavity is filled with metal damping particles.Discard traditional rubber, single damping form of spring fixed damping, utilize the free collision, friction, shearing action of metal damping particles in closed storage cavity, can simultaneously adapt low-frequency large amplitude jolt vibration and high-frequency subtle resonance in the process of vehicle driving.Particle dynamic movement in cavity reserved gap, can consume vibration energy of different frequency, different amplitude, solve the defect of traditional structure damping band narrow, poor adaptability, all-around weaken steering wheel shaking, microseismic problem, effectively optimize whole vehicle handling comfort.
