Steering tie rod with built-in space folding beam local resonance damper and damping performance parameter estimation method

Abstract

The invention discloses a steering tie rod with a built-in space folding beam local resonance damper. Two ball bearings are fixedly mounted at the two ends of a hollow connecting rod through threads; a local resonance shock absorber is fixedly mounted in the hollow connecting rod through the external protection type frame; and an external protection type frame is located on the outer side of the shock absorber, is mainly used for providing a mounting base of the shock absorber and serves as a main part for fixing the shock absorber and the interior of the hollow connecting rod. The local resonance damper comprises a space folding beam elastic element and a scatterer; the space folding beam elastic element is embedded in the inner side of the external protection type frame and is in close fit with the external protection type frame, and the scatterer is fixed on the inner side of the space folding beam elastic element; the steering tie rod is used for transmitting steering force of a steering engine to a steering knuckle in the vehicle running process; and the impact vibration reversely transmitted to the steering engine by the steering knuckle in the steering system is attenuated through a local resonance type shock absorber arranged in the transverse pull rod.

Description

technical field [0001] The invention relates to component vibration reduction of vehicle components, in particular to a steering tie rod suitable for a built-in space folding beam local resonance shock absorber of a vehicle. Background technique [0002] The steering tie rod is one of the main parts of the vehicle chassis system. During the running of the vehicle, its main function is to connect the steering gear and the steering knuckle, and transmit the steering force output by the steering gear to the steering knuckle. During the driving process of the vehicle, the excitation of the road surface is transmitted to the steering gear and the body through the wheels and steering knuckle through the steering tie rod, resulting in a series of vibration problems of the vehicle. At the same time, since the steering tie rod, steering gear and steering knuckle are often rigidly connected, it is difficult to complete the vibration reduction work by setting traditional vibration dam...

AI Technical Summary

Problems solved by technology

At the same time, since the steering tie rod, steering gear and steering knuckle are often rigidly connected, it is difficult to complete the vibration reduction work by setting traditional vibration damping elements (such as vibration damping sleeves, etc.) in the vibration transmission path. Will significantly increase the complexity of the structure of the vehicle chassis components
