AI Technical Summary
When the existing damper extends and retracts at high speed, the flow area of the secondary valve becomes a bottleneck, resulting in excessive damping force and affecting the ride comfort of the vehicle.
The main channel and the secondary channel are connected in parallel. The main damping force generating element and the secondary damping force generating element are respectively set on the main channel and the secondary channel. The flow area of the secondary valve does not become a bottleneck, and the damping force characteristics are adjusted by a variable throttling orifice.
Without being affected by the overload of the secondary valve, the vehicle's ride comfort is improved and the damping force characteristics are optimized, especially the damping force performance in different speed ranges.
