Vehicle vibration damping system for tractor, has inertia element whose inertia force works during arising of vibratory movements from upper part on actuators for readjusting of parameter of suspension element to change transfer function

摘要

The system has a vehicle seat lower part (2) e.g. vehicle base frame, and a vehicle seat upper part (1) swingably movable relative to each other by a spring suspension element (9) i.e. pneumatic spring. An inertia element (12) e.g. mass element, is provided on the vehicle seat upper part, where the inertia force of the inertia element works during arising of vibratory movements from the vehicle seat upper part on actuators (11, 14, 15) e.g. lever mechanism, for continuous readjusting of a spring suspension-relevant parameter of the suspension element to change a vibration transfer function.
