Abstract:
A roll stabilizer for a motor vehicle having a body structure and a pair of dirigible wheels connected to said body structure by respective ones of a pair of suspension control arms pivotable up and down on said body structure comprising:a split U-shaped torsion bar having a first L-shaped element and a second L-shaped element,a bearing means operative to support a lateral segment of each of said first and said second L-shaped elements on said body structure for independent rotation about a lateral centerline of said body structure,a link means operative to connect a distal end of a longitudinal segment of each of said first and said second L-shaped elements to respective ones of said pair of suspension control arms,a mechanical coupling means operative to selectively couple and uncouple said lateral segments of said first and said second L-shaped elements when said mechanical coupling means is engaged and disengaged to change the effective torsion modulus of said split torsion bar from maximum when said mechanical coupling means is engaged to zero when said mechanical coupling means is disengaged, andan actuator means suspended on said mechanical coupling means operative to engage and disengage said mechanical coupling means.
