"Torsion beam suspension" redirects here. Not to be confused with Torsion bar suspension.
The twist-beam rear suspension (also torsion-beam axle, deformable torsion beam, or compound crank) is a type of automobile suspension based on a large H- or C-shaped member. The front of the H attaches to the body via rubber bushings, and the rear of the H carries each stub-axle assembly, on each side of the car. The cross beam of the H holds the two trailing arms together, and provides the roll stiffness of the suspension, by twisting as the two trailing arms move vertically, relative to each other.
