VARIABLE STIFFNESS STABILIZER DEVICE

Title:

VARIABLE STIFFNESS STABILIZER DEVICE

Document Type and Number:

WIPO Patent Application WO/2008/041727

Kind Code:

A1

Abstract:

A variable stiffness stabilizer device (1) has a stabilizer bar (2) and actuators (3). The stabilizer bar (2) has a torsion bar (4) extending in the lateral direction (X1) of a vehicle and arms (6) connected through bent parts (5) to the ends (4a, 4b) of the torsion bar (4) and bend and deformed according to the strokes of wheel support members (11). Variable bending stiffness parts (13; 130) of the arms (6) are rotatable about the axes (C1) of the arms (6), so that the bending stiffness of the arms (6) can be changed according to their rotational positions. The actuators (3) rotate the variable bending stiffness parts (13; 130) about the axes (C1) to adjust the rotational positions of the variable bending stiffness parts (13; 130).
