AI Technical Summary

Technical Problem

The existing hydraulic suspension system has an insufficient damping frequency range, which cannot meet the damping requirements of automobiles under various operating conditions, and the frequency control range cannot be changed by adjusting the damping fluid capacity.

Method used

An electronically controlled three-chamber variable semi-active hydraulic suspension system is adopted. Through the design of the baffle and limit plate, combined with the servo signal of the vibration detection system, the control coil is activated according to the working conditions to control the baffle to separate the main liquid chamber and the auxiliary liquid chamber. The baffle, which uses elastic and magnetic materials, achieves effective separation and flow control of the damping oil.

Benefits of technology

It enables dynamic adjustment according to working conditions, enhances the vibration reduction capability of the hydraulic suspension system, improves the frequency control range, enhances the decoupling effect under high-frequency vibration, and improves the overall NVH performance of the vehicle.

Abstract

本发明公开了一种电控三液室可变式半主动液压悬置系统,一种电控三液室可变式半主动液压悬置系统,所述三液室包括通过挡体分隔的主液室和副液室以及与主液室导通的下液室;主液室上方设有限位板,挡体及挡体的控制线圈设置在限位板内。本发明通过上述设置,配合振动检测系统的舵机信号判断液压悬置系统工况,根据不同工况下的减振需求,选择是否激活控制线圈,控制挡体分隔主液室和副液室。
