Stabilizer bar assembly with variable roll stiffness

Abstract

The present disclosure relates to a stabilizer bar assembly with variable roll stiffness operating such that lower stiffness acts during straight driving and higher stiffness acts during cornering. The assembly includes an outer housing secured to a first stabilizer bar to rotate together and having a hollow space inside, an inner housing secured to a second stabilizer bar to rotate together and inserted into the outer housing to rotate relative thereto, and an elastic member having one end secured to the outer housing and the other end secured to the inner housing to apply an elastic force to return the outer housing and the inner housing to their original positions during relative rotation. In this configuration, lower stiffness by an elastic force of an elastic member acts during straight driving to enhance ride comfort during straight driving, and higher stiffness by a stabilizer bar acts during cornering to improve driving stability.
