A rear suspension system includes a plurality of trailing arms, a beam defining a space therein, and a plurality of reinforcing members, each with a first end connected to a respective one of the trailing arms and a second end contacting an interior surface of the beam. The second end of each reinforcing member is branched into two portions with a rod disposed between them. Each reinforcing member has at least one and preferably two curved portions, one near each end, both curved along the beam axis such that the second end of the reinforcing member is parallel with the rod.

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.

A torsion beam axle suspension is provided, in which a shock absorber is directly mounted on right and left trailing arms and is further mounted to the mount by a ball joint. Thus, it is possible to reduce the weight and production expenses, thus to enhance productivity. Further, it is possible to considerably decrease a friction caused by movement of the shock absorber even though the transverse force is applied, thus to enhance the riding comfort.

A vehicle axle assembly having an axle housing, an axle shaft and a sensor. The axle housing has a tubular portion. A flat is formed on an annular wall of the tubular portion proximate a distal end of the tubular portion. A hole, which intersects the flat, is formed through the tubular portion. The axle shaft can have an integrally formed target portion that includes a plurality of teeth. The sensor is mounted in the hole and abuts the flat to space a tip of the sensor apart from the teeth of the target portion by a predetermined distance.

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.

A coupled torsion beam axle type suspension system (CTBA) may include trailing arms respectively coupled to opposite ends of a torsion beam, and a vehicle body-engaging unit provided in a front end portion of each of the trailing arm and engaging the each of the trailing arms to a vehicle body, wherein each vehicle body-engaging unit includes a trailing arm bush that may be coupled to a front end portion of the trailing arm, a rotation link disposed in front of the trailing arm bush and engaged thereto in a width direction of a vehicle, a slider rotatably connected to a front end portion of the rotation link, and slidable along a length direction of the vehicle body, and a connection link pivotally connecting an outer end portion of the rotation link and the vehicle body.

The invention discloses a construction technique, that the motion of prefabricated beam on the base and the track, which can be used in box-beam moving vehicle of passenger transport special railway line. It is characterized in that: it comprises a flexible support vehicle, and two steel support vehicles, which are independently arranged on four tracks at two sides of beam producing field; and it also comprises a speed detector, a force detector, an alarm device, a hydraulic controller and an electric appliance controller. Wherein, the flexible support vehicle is formed by four driving single vehicles, four driven single vehicles, a hydraulic mechanical lock, a hydraulic support, a solid beam axle, a solid beam and a outer frame beam; the rigid support vehicle is formed by two driving single vehicles, two driven single vehicles, a small balance beam, a speed sensor, and a hydraulic support; the power transmission is completed by the transmission device of motor speed reducer via gear wheel to drive wheels; the walking of driven single vehicle is transmitted via small balance beam; the speed detector detects the synchronous property of walking; the force detector detects if the force is over the preset value; the whole support capacity can reach 900t. The invention has stable working and easy operation with beam lifting-moving functions.

The present invention relates to a tubular beam of a torsion beam axle type suspension, which includes a uniform cross-sectional portion with the smallest tail radius and cross-sectional width throughout the tubular beam, a variable cross-sectional area that extends from the uniform cross-sectional portion and gradually increases in the tail radius and cross-sectional width, and an enlarging cross-sectional portion that extends from the variable cross-sectional portion. Therefore, it is possible to minimize reduction of roll rigidity and improve durability of a tubular beam. Further, it is possible to add understeer characteristics to a tubular beam with an oversteer tendency by minimizing the reduction in transverse rigidity and making a shear center higher.

A drive axle and suspension assembly for a vehicle having a power source and wheels including a torsionally compliant twist beam suspension and a driveline assembly. The twist beam includes a twist element defining a first lateral axis and arm portions adapted to rotatably support the wheels of the vehicle along a second axis extending substantially parallel to the first axis. The driveline assembly is adapted to receive torque from the power source and drive the wheels. The driveline assembly includes a plurality of power transmission rotatably supported by arm portions.

The invention discloses a novel slipway beam for incremental launching construction. The beam comprises a front slipway beam, a back slipway beam and a middle slipway beam which have box-shaped structures and are connected into a whole through bolts, wherein an upper surface on the back part of the back slipway beam is provided with a concave pit; four vertical lifting jacks are vertically arranged in the concave pit and arranged in an array form along the axial central cross section of the back slipway beam; the back end face of the beam slipway beam is provided with a support platform; a horizontal continuous lifting jack is arranged on the support platform; the left and right sides of the upper surfaces of the front, back and middle slipway beams are provided with stainless steel plates respectively; and traction rope insertion pipes are arranged inside the front, back and middle slipway beams along the length directions of the front, back and middle slipway beams. The slipway beam has the advantages of ensuring the continuity of horizontal lifting, projecting and longitudinal movement in a steel beam pier-passing process well, bringing convenience to field construction, saving construction period, avoiding additional arrangement of temporary individual projecting and horizontal lifting structures and saving construction cost.
