A beam axle, rigid axle or solid axle is a dependent suspension design, in which a set of wheels is connected laterally by a single beam or shaft. Beam axles were once commonly used at the rear wheels of a vehicle, but historically they have also been used as front axles in rear-wheel-drive vehicles. In most automobiles, beam axles have been replaced by front and rear independent suspensions.

A cross-member for a motor-vehicle twist-beam axle suspension includes a single piece of steel that defines a closed cross-section and integrally forms a middle section, a pair of end sections, and a pair of joining sections. The middle section has a center axis extending along a curvilinear path lying in a first plane and a squashed portion extending in a second plane inclined to the first plane. The end sections are adapted to be securely connected to respective trailing arms of the twist-beam axle suspension. Each of the joining sections is interposed between the middle section and the respective end section and defines an opposite concavity with respect to the middle section. A twist-beam axle suspension for a motor vehicle includes the cross-member and a pair of trailing arms. A method produces the cross-member for a motor-vehicle twist-beam axle suspension.

Twist Beam With Interlock
ActiveUS20100301577A1Increase flexibilityIncreased bending stiffnessInterconnection systemsWheel manufactureControl armFront-wheel drive
In a front wheel drive vehicle a traditional twist beam axle suffers from a short service life due to premature failures in intermediate areas between the end sections and the transitional section. A twist beam suspension is provided comprising a transverse strut (16) interconnecting longitudinal control arms (12). The transverse strut (16) may be formed from a tubular pipe. The tubular member may define a pair of tubular end sections (18), a deformed, U-shaped transitional section (20), and a pair of intermediate sections (22) between the end sections (18) and the transitional section (20). The intermediate section (22) may define a contour (28), known as a tongue. The tongue (28) enhances the flexibility in torsion and improves the stiffness in bending of the transverse strut (16). The tongue (28) may also include a concavity, to further aid in improving stiffness.

Torsion beam type suspension, method for forming torsion beam, and apparatus for forming torsion beam
ActiveUS20050035567A1Increased torsional stiffnessImprove rigidityMetal-working apparatusInterconnection systemsInterior spaceEngineering
A torsion beam type suspension and a forming method of a torsion beam are disclosed. 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.
