Abstract: Disclosed herein are a torsion beam type suspension and a forming method of a torsion beam. In the torsion beam type suspension comprising a pair of left and right trailing arms connected to each other through a torsion beam, front ends of the trailing arms being used to mount a vehicle body by using joints, the torsion beam is obtained by forming an overall length of a pipe having a certain wall thickness by using a pressure forming process. In this case, end sections defined at both end portions of the torsion beam have a cross-sectional shape of a hollow oval, a center section defined at a center portion of the torsion beam has a cross-sectional shape of a hollow open loop, and middle sections defined between the center portion and both the end portions of the torsion beam have a cross-sectional shape of a hollow open loop. The loop of the middle sections defines an inner space larger than that defined by the loop of the center section. Further, since the torsion beam can be easily formed by adopting a hydro-forming process, it is possible to achieve high twisting rigidity, bending rigidity, and durability without requiring a torsion bar and reinforcement, which must be inevitably assembled to a conventional torsion beam axle, resulting in a reduction of the number of constitutive elements and the overall weight.

Abstract: An adjustable anti-roll bar having a single set of mounting apertures whose roll rate is adjusted in the middle of the anti-roll bar. The roll rate is determined by the location of the junction of one torsion member to another; that is, an outer torsion member to an inner torsion member. In order to account for the presence of certain automotive components in the undercarriage area, the geometry of the anti-roll bar may be changed. The second embodiment meets this challenge for a specific vehicle by using two weldments of a specific size to relocate the adjustable middle section. Changing the length and angle of the lever arms of the first embodiment can do the same thing in many instances.

Abstract: Vehicle suspension movements are transmitted to an anti-roll mechanism which is pivotally mounted on the vehicle for movement about the pitch axis thereof to accommodate normal ride motion of the vehicle in which wheels on opposite sides of the vehicle move equally. Vehicle roll is controlled by an anti-roll mechanism includes a torsion bar which is loaded by the suspension movement. Roll stiffness is controlled by adjusting the lever arm through which suspension movement is transmitted to the torsion bar by a lever arrangement commonly referred to as a Watt's link to assure that the change in the length of the lever arm is directly proportional to the change in the control in the cockpit. Accordingly, linear control is assured, and the torsion bar and lever arms do not appreciable deflect during cornering.
