Active antiroll device for automotive vehicles, automotive vehicle and method for modifying the roll performance of a suspension in an automotive vehicle

摘要

The invention relates to an active antiroll device for automotive vehicles, automotive vehicle and method for modifying the roll performance of a suspension in an automotive vehicle, comprising a stabilizer bar (5) with a central part (8) articulated in two supports (13) to a front cradle (12) of an automotive vehicle, said central part (8) extending beyond each support (13) in a cantilever part (7), each cantilever part (7) being bent into a lever arm (6) which connects at its end, in a support point (9), with a connecting rod (14) which at its opposite end connects with an intermediate element which transmits the forces exerted in the wheels, for example a shock absorber (15) of the suspension of the automotive vehicle, where the device comprises means for modifying the torsional moment of the central part (8) of the stabilizer bar (5) over time.
