Voice coil motor active suspension

Abstract

The invention discloses a voice coil motor active suspension, which relates to the technical field of vehicle suspension vibration reduction, and comprises a suspension shell part, a passive vibration reduction loop component and an active vibration reduction loop component, the passive vibration reduction loop component and the active vibration reduction loop component are both arranged in the suspension shell part, and the passive vibration reduction loop component is arranged between the active vibration reduction loop component and the suspension shell part. The top of the passive vibration reduction loop component and the top of the active vibration reduction loop component are both connected with the load end of the suspension shell part. A voice coil motor can be actively controlled to generate exciting force according to real-time working conditions so as to counteract vibration interference, high vibration reduction efficiency is achieved, and the voice coil motor active suspension is suitable for vibration reduction of a vehicle suspension system with high requirements for comfort and stability.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension vibration reduction, in particular to a voice coil motor active suspension. Background technique [0002] At present, in the field of vehicle manufacturing, the demand for improving the comfort and stability of vehicles is getting higher and higher, so the requirements for the isolation of vehicle vibration are becoming more and more stringent. In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the vehicle, the connection of the vehicle is generally through the suspension system. The quality of the suspension system will directly affect the comfort and stability of the vehicle. and the life of other components. [0003] At present, the suspension and damping devices of vehicles mainly include rubber mounts, hydraulic mounts and air spring mounts, etc. Among them, the rubber mounts have a simple structure and low cost, but t...

AI Technical Summary

Problems solved by technology

Hydraulic mounts can obtain high-frequency low stiffness and reduce high-frequency hardening to a certain extent, but their structures are complex and require high sealing performance

The air spring mount has a lower natural frequency, better adaptability and versatility to different road surfaces, and its own vibration and noise during operation is relatively small, but it also has the problems of high sealing, processing and installation accuracy
