Abstract: The present disclosure relates to a semi-active stabilizer device which may adjust the rigidity of a stabilizer bar according to a traveling state of a vehicle, and may include a first stabilizer bar, a second stabilizer bar, an outer housing which has a hollow portion formed therein, an inner housing which is inserted into the hollow portion of the outer housing to rotate relatively, an elastic member which applies an elastic force so that the outer housing and the inner housing return to original positions thereof upon relative rotation, and a stopper which limits the inner housing to rotate relatively only within a certain angular range upon the relative rotation, thereby improving riding comfort upon traveling on a straight road, and improving traveling stability upon traveling on a curved road.

Abstract: A semi-active anti-roll stabilizer bar capable of controlling the stiffness thereof by virtue of the elastic force of a spring is disclosed. When the stabilizer bar is rotated during general travelling, the stabilizer bar has roll stiffness attributable to the repulsive force due to the spring constant thereof. When the stabilizer bar is greatly rotated during turning of the vehicle, the springs are closely compressed, with the result that the stabilizer bar has the same high stiffness as that of a general stabilizer bar.

Abstract: An apparatus for mounting a stabilizer bar to a vehicle body frame is disclosed. The stabilizer bar mounting apparatus (1) of the present invention includes a rubber bushing (10), metal plates (30) and a mounting bracket (20). The rubber bushing (10) includes a main body (100), which has a holding hole (100a) for insertion of the stabilizer bar (2), and has a slit (100b) extending from an upper surface thereof to the holding hole (100a). Elastic holes (101) are formed in each of the opposite ends of the main body (100) to reduce stiffness of the main body in a rotational direction. The metal plates (30) are inserted into the main body of the rubber bushing (10) to prevent the rubber bushing from being deformed. The mounting bracket (20) includes a bushing receiving part (200) and a pair of mounting plates (201), which are provided on respective opposite edges of the bushing receiving part, so that the mounting bracket receives and fastens the rubber bushing to the vehicle body frame.
