Suspension arrangement

The invention relates to a method for dampening control in a vehicle suspension, wherein a suspension arrangement for each wheel includes at least two linkages (8, 10) connecting a wheel (5) to a chassis (1) that is part of a vehicle body, and where a torsion spring unit (6) is part of one of said linkages. The torsion spring unit (6) has an adjustable spring rate and that the spring rate is adjusted instantaneously to dampen oscillations in each individual suspension. An arrangement for perofrming said method is also disclosed.
