The present invention is characterized in that in a torsion beam suspension 100 in which to right and left trailing arms 50 extending in a front-rear direction of a vehicle body and swinging vertically, a torsion beam 16 extending in a right and left direction of the vehicle body is joined, two or more types of rigidity adjustment portions 15, 18, 24 and 25 which adjust a rigidity from the trailing arms to the torsion beam are disposed with positions of the rigidity adjustment portions displaced from each other.

A pneumatic control system includes a manifold that defines: a channel for conveying a fluid, a discharge port, a drain port, and an expansion chamber defining a chamber axis. The discharge port defines a flow axis extending between a first end and second end and a receiving region at the second end. The pneumatic control system also includes a filter assembly with a filter member disposed in the expansion chamber, and an actuator configured to selectively control fluid communication between the channel and the discharge port. The chamber axis is substantially coplanar with the flow axis. A filter cap assembly includes a filter cap body enclosing an end of the expansion chamber and selectively removable from the manifold to provide access to the filter assembly. A purge valve body is configured to selectively control fluid flow between the expansion chamber and the drain port.

A tubular spring, such as a coil spring, a torsion-rod spring, and/or a stabilizer for motor vehicles, may comprise at least one metal tube element having a tube internal cross section, a tube internal diameter, a tube external diameter, a tube internal wall, and a tube wall thickness. At least one metal foam may be disposed in the tube internal cross section of the at least one metal tube element of the tubular spring in at least one part-region. The metal foam may be connected in an at least partially materially integral manner to the tube internal wall of the metal tube element. Further, the at least one metal tube element may have an at least partially martensitic structure.

A paint spraying apparatus includes a supporting structure, a lower nozzle unit, and an upper nozzle unit. The lower nozzle unit includes lower flexible tubes and nozzles, and ejects powder paint toward an eye portion on a lower side of a stabilizer. The upper nozzle unit includes a first frame and a second frame. First flexible tubes are arranged on the first frame. Second flexible tubes are arranged on the second frame. The upper nozzles eject the powder paint toward an eye portion on an upper side of the stabilizer.

A stabilizer includes a stabilizer main body, and eyes formed on both ends of the stabilizer main body. Through-holes are formed in fastening surfaces of the eyes, respectively. The stabilizer main body is covered with a main body coating film. The eye is covered with an eye coating film whose thickness is less than a thickness of the main body coating film. An inner surface of the through-hole is covered with an inner surface coating film. An incomplete coating portion is formed at a part of the inner surface of the through-hole in a circumferential direction. The incomplete coating portion is located on an extension of a straight line connecting a center of the through-hole and the center of gravity of the stabilizer main body in a side view of the stabilizer main body.

The present disclosure provides a transverse link for a wheel suspension of a vehicle that includes at least one wheel-side attachment structure and at least one structure-side attachment structure. The wheel-side and structure-side structures are connected to each other by a connection structure which extends therebetween. The connection structure and/or at least one of the attachment structures is/are produced by a generative production method. At least one of the attachment structures is constructed as a generatively produced bushing which has an inner sleeve and an outer sleeve surrounding the inner sleeve. The sleeves are connected to each other by a fold-like structure. The present disclosure further provides a method for producing such a transverse link.

A method for producing a stabilizer and a heating device allows the entirety of a hollow member to be uniformly heated to a temperature necessary for heat treatment, even in a case in which a cross section varying hollow member is used as the starting material. In a preliminary heating process, energizing heating is performed between electrodes, which are arranged at cross section varying parts at both ends of large cross sectional area part, which can be heated. In an entire heating process, by performing energizing heating between electrodes, which are arranged at both ends of the cross section varying hollow member, the latter can be heated. In the preliminary heating process, it is desirable to perform energization heating at a part having a cross sectional area ratio of 90% or more with respect to the part having a large cross sectional area in the cross section varying part.

This disclosure relates to methods for obtaining a suspension arm for automotive vehicles, wherein certain embodiments comprise obtaining two identical parts to form a body, where each part is obtained by means of: a) cutting a metal or composite sheet forming a base plane, such that a central segment and two ends are defined, b) drawing at least one hole in each end, c) stamping each part forming in its central segment two flanges consisting of a first flange and a second flange located on opposite sides of the central segment and oriented perpendicular to the base plane, where said flanges have an asymmetrical arrangement with respect to a midplane passing through the geometric centers of the holes of the two ends and is perpendicular to the base plane, the second flange being separated from the midplane a distance equal to the separation of the first flange from the midplane plus a distance at least equal to the value of the thickness of the sheet or plate.

The present invention relates to a link arm for connecting a first unsuspended mass to a second suspended mass, and its manufacturing method. The invention applies in particular to a suspension system for a motor vehicle, wherein the arm is able to equip a wheel suspension by having triangular housings to receive a stub axle of the wheel and two connecting links to the chassis of the vehicle. This arm (1) comprises housings (14, 15, 16) to receive a first linkage joint (14a) to the first mass, and at least a second linkage joint (15, 16) to the second mass, and comprises: a stiffening portion (2) which comprises a first thermoplastic or thermosetting matrix composite material reinforced with fibers and which comprises a peripheral rim (8) of the arm, and an anti-buckling portion (3) interposed in the stiffening portion and extending from the rim over substantially the entire arm.

According to the invention, the fibers are continuous and united in the form of a main skein of first fibers extending along the rim, which encloses the anti-buckling portion.

The present application is directed to an externally adjustable internal bypass shock absorber that combines both the suspension function and the shock absorbing function in one unit. More particularly, the shock body houses a bypass cylinder that includes an upper bulkhead with adjuster rod pockets and check valves as well as a lower bulkhead having one or more check valves. The bypass cylinder includes one or more bypass tubes within bypass tube accepting cavities, in fluid communication with bypass adjuster valve blocks controlling the flow of hydraulic fluid within the bypass tubes. Adjuster rods are telescopically received inside the bypass adjuster block valves for controlling whether the individual oil flow ports are closed, partially open, or fully open. These adjuster rods provide an actuation means in the damper for manual or non-automatic adjustment allowing high speed and low speed as well as sway control on the external shock surface.
