AI Technical Summary

Technical Problem

Existing vibration damping devices use passive buffering and damping based on the flow of the working medium, resulting in long response times and complex structures.

Method used

The mechanical structure design employs a transmission cam and an actuator assembly. The actuator assembly is driven to move along the axial direction by the guide structure of the transmission cam, thereby achieving vibration reduction.

Benefits of technology

It achieves faster response speed and stronger adjustment capability, while maintaining a simple structure.

Abstract

The invention relates to the technical field of vehicle parts, in particular to a damping device, a suspension system and a vehicle. The damping device comprises a transmission cam and an execution assembly, and the transmission cam is provided with a guide structure; the execution assembly is in matched transmission with the guide structure, and when the transmission cam moves, the execution assembly is driven to move in the axis direction of the transmission cam. In the damping device, an execution assembly and a guide structure are in matched transmission, when a transmission cam moves, the transmission cam drives the execution assembly to move in the axis direction of the transmission cam, the execution assembly moves to drive a to-be-damped part connected with the execution assembly to move in the axis direction of the transmission cam, and therefore damping is achieved. The damping device achieves damping through matched transmission of the guide structure and the execution assembly in the transmission cam, damping is achieved through a mechanical structure, and the damping device has the advantages of being higher in adjusting capacity and higher in response speed.
