Abstract
The invention relates to an active suspension assembly and a vehicle equipped therewith. The assembly comprises a bearing arm, spring and adjusting mechanism. In use, the bearing arm supports the second vehicle mass, for instance a cabin or wheel and is pivotally connected to the first vehicle mass, for instance a chassis, around a pivot axis; the spring mechanism produces a spring force that exerts a counter moment on the bearing arm that can counterbalance any external moment acting on said bearing arm; and the adjustment mechanism is arranged to vary said counter moment by altering the direction of the spring force and/or move its point of application in a first direction. The adjustment mechanism is furthermore arranged to move the point of application of the spring force in a second direction, in which the counter moment is not or hardly affected, but by which the effective spring stiffness of the suspension assembly is affected. Thanks to said latter movement, the effective stiffness of the suspension can be maintained at a desired value.
