Abstract
The invention provides a transverse stabilizer bar device capable of automatically adjusting rigidity of a stabilizer bar in the run-out process of a vehicle, aiming at solving problems that the arrangement space and the controllability of the traditional transverse stabilizer bar are insufficient. The transverse stabilizer bar device comprises a transverse stabilizer bar which is formed by hinging two symmetrical transverse bars; the end part of the external side of each transverse bar is respectively movably connected with a lower swinging arm of an automobile by using an end part bracket; the middle part of the bar body of each transverse bar is respectively connected to an automobile frame by using a connecting bracket. The end parts of the transverse stabilizer bar generate certain displacement relative to the lower swinging arm in the run-out process of wheels, so that the rigidity of the stabilizer bar is changed automatically and reduced gradually along with the increase of the run-out amplitude of the wheels. When the side-dumping amplitude of the vehicle is lower, the transverse stabilizer bar has larger rigidity, thereby side-dumping is prevented; when the side-dumping amplitude of the vehicle is larger, the transverse stabilizer bar has reduced rigidity, thereby attachment force between an inside tire and the ground is increased, and controllability and comfortableness are increased.
