一种轻量型旁通减震器

By incorporating a gradient groove design for the built-in bottom and top valve cores and adjusting the drive components, combined with negative pressure intake and positive pressure exhaust components, the problems of sudden damping force changes and large size in existing bypass shock absorbers are solved. This achieves smooth damping force adjustment and weight reduction, and improves the heat dissipation performance and stability of the shock absorber.

AI Technical Summary

Technical Problem

The damping force adjustment of existing bypass shock absorbers cannot be adjusted according to actual needs, which can easily cause a sudden change in damping force when opening or closing, resulting in a shock feeling. At the same time, the external pipeline makes the shock absorber bulky and cannot achieve lightweight design.

Method used

A lightweight bypass shock absorber is designed, which adopts a built-in bottom valve core and a top valve core, and achieves adaptive and continuous adjustment of damping force through a gradient groove and a drive component. A negative pressure air intake component and a positive pressure exhaust component are set at the bottom of the outer cylinder for passive heat dissipation.

Benefits of technology

It achieves smooth adjustment of damping force, avoiding the impact caused by sudden changes in damping force. At the same time, it achieves lightweight through built-in structure and improves the heat dissipation performance and working stability of the shock absorber.

Abstract

本发明公开了一种轻量型旁通减震器,涉及减震器技术领域。包括内筒、外筒、顶部阀组和底部阀组,所述内筒内设置有底部阀杆,外筒底部固定有顶部阀杆,底部阀杆和顶部阀杆之间可拆卸式固定。本发明设置底部阀芯和顶部阀芯,实现了阻尼力随活塞行程位置的自适应连续平滑调节,当小振幅振动时,阀芯保持初始位置,旁通孔全开,油液经旁通油路流动产生低阻尼力,保证舒适性,当振幅增大时,油液压差推动阀芯移动,阀芯遮蔽旁通孔使流通截面积减小,同时油液流经的渐变槽段由浅窄段向深宽段过渡使节流阻力减小,二者相互补偿,实现阻尼力平滑上升,无阶跃突变,解决了现有技术中阻尼力突变产生的冲击感问题。
