An overmolded steel-TPU outer member raises jounce bumper stiffness to handle 150 kN loads while limiting suspension overtravel and NVH.

A common controller uses motor position and pump pressure feedback to regulate active axle damping accurately under dynamic vehicle loads.

Fluid pressure tuning shifts damper rigidity and natural frequency to suppress multi-frequency vibration in magnetic force stage systems.

Radial openings in a resilient wheel insert absorb rolling shocks, protecting luggage contents without complex coil spring assemblies.

Dead zone stroke segmentation raises damping only near full extension and compression to cut suspension impact, noise, and wear.

Rotating a coaxial control disc opens or blocks damper flow channels for precise manual damping adjustment without spring pretension losses.

A rotatable control disc varies damper fluid channels to simplify precise damping-force tuning for soft or hard suspension settings.

A hollow rod serves as the volume compensation chamber, cutting damper size and weight while preserving heat dissipation in solar panel arrays.

Combining elastic members with hydraulic pressure boosts damping force in a compact shock absorber, improving ride comfort and stability.

Oblique protrusions between elastic-body voids raise suspension bushing rigidity for handling while preserving ride comfort and durability.

Two separate accumulators let suspension fluid bypass pump inertia, preserving stiffness across frequencies and reducing rough ride.

An internal IFP location sensor derives shock stroke position for active suspension control of bottom-out, stiffness, preload, and ride height.

A shear-thickening fluid and piston slow temporary suspension airflow changes, cutting wasted pressurized air and fuel use.

A stiffness adjustment plate and spring tune damper valve shim deflection resistance without shim replacement or preload change.

A spring-loaded insert and sealing structure absorb train coupler forces and block dust, extending linear actuator life without pneumatics.

Nested poppet valves relieve damper chamber pressure without added dead length, reduced travel, or cavitation noise from blow-off flow.

Electromagnets vary MR fluid viscosity in a spring seat to switch suspension stiffness quickly without complex mechanical rate-changing parts.

A 3-DOF and 1-DOF bearing layout keeps torsion and lateral loads out of a composite leaf spring, reducing breakage risk and weight.
