Abstract
This paper presents the working principle of adjustable pistons, the design of split valve train, sealing issues, and the latest research progress of magnetorheological technology.

Core Key Points
The adjustable piston changes the cross-sectional area of the bypass oil circuit by regulating the central needle valve.
It enables real-time adjustment of damping force and is compatible with millisecond-level automatic CDC control systems.
The split valve train design expands the damping adjustment range, with no mutual interference between the main valve and bypass circuit.
Disadvantages: Precisely fitted components are prone to wear and internal oil leakage, accompanied by high manufacturing costs.
Sediment and silt intrusion may cause jamming of mechanical threads, resulting in poor adaptability to harsh operating environments.
Magnetorheological and electromagnetic valve technologies are gradually replacing the mechanical needle valve structure.
Detailed Content
With the continuous improvement of vehicle dynamic performance requirements, traditional fixed-damping shock absorbers can no longer meet the demands of multi-scenario driving. Accordingly, adjustable piston mechanisms have been widely applied in high-performance vehicles, modified vehicles and some luxury passenger cars.
