Protection against excessive forces in a suspension arrangement

Jarkko Keinänen (Inventor), Kalle Vehviläinen (Inventor), Ismo Vessonen (Inventor)

Research output: PatentPatent


A simple and robust suspension arrangement is provided for taking into account different suspension modes without the need for excessive sensoring or electronics. The novel suspension arrangement includes a first suspension element, which directly suspends the object to the frame, and a second suspension element, which suspends the object to the frame through a magnetic coupling between the object and the second suspension element. The magnetic coupling provides a magnetic coupling force (Fh) to act as a threshold such that the suspension arrangement is designed to magnetically decouple the second suspen-sion element from the object when the excitation force (Fe) transmitted be-tween the frame and the object exceeds the magnetic coupling force (Fh).
