用于减振器的阻尼阀装置

By forming the guide surface from the outer side of the piston rod in the damper and fixing the valve seat in the cylinder, and using the piston rod guide to form the valve seat, the assembly and damping force characteristics of the damping valve device are optimized. This solves the problems of high assembly costs and difficulty in optimizing damping force characteristics in the prior art, and achieves more efficient damping force adjustment and vibration reduction effect.

AI Technical Summary

Technical Problem

Existing damping valve devices in vibration dampers suffer from high assembly costs and difficulty in optimizing damping force characteristics.

Method used

The flow guide surface is formed from the outer side of the piston rod, and the valve seat is fixed in the cylinder. The valve seat is formed by the piston rod guide to optimize the assembly. The flow channel is designed by the annular gap between the piston rod and the cylinder to reduce leakage. The damping force characteristics are adjusted by the combination of multiple valve elements and pressure chambers.

Benefits of technology

The assembly efficiency of the damping valve device was improved, the damping force characteristics were optimized, and better damping force adjustment and vibration reduction effects were achieved.
