Wheel suspension with piston and spring in parallel - has system for increasing passive stiffness of spring

摘要

The arrangement is for damping a sprung wheel suspension for a vehicle. It has a piston displaceable in a cylinder and dividing it into two working chambers, with the piston and cylinder arranged in parallel with a spring. A dynamic wheel load (Cr) in the region of the wheel eigenfrequency is reduceable by intervention in the damping element (4) by means of a frequency-dependent increase in the passive spring stiffness of the spring (3). USE/ADVANTAGE - Minimising wheel load to give greater safety and improved ride comfort.
