An electric resistance welded steel pipe for manufacturing a hollow stabilizer has a Rankford value in a pipe longitudinal direction of from 0.7 to less than 1.0. The electric resistance welded steel pipe is subjected to cold bending and then to a heat treatment including quenching and tempering to manufacture a stabilizer. The cold bending is cold rotary draw bending. When bent with a bend radius of from 1.0 times to 3.0 times an outer diameter of the pipe before cold bending, a flattening ratio is from 0% to 10%, a thickness reduction rate on a bending outside and a thickness increase rate on a bending inside are from 0% to 10%, and additionally, a circumferential length change of a bending center portion is from 0% to 10%. A Vickers hardness of the stabilizer after the heat treatment is adjusted to from 400 HV to less than 580 HV.

A torsion spring arrangement for a wheel suspension of a motor vehicle, including two torsion bars arranged coaxially one inside another and also a spring element, which is arranged axially-parallel to the two coaxial torsion bars and can be mounted on the motor vehicle body via a bearing position, wherein the radial outer hollow-cylindrical torsion bar can be mounted on the motor vehicle body side and is connected in a rotationally-fixed manner to an output lever fastenable on a wheel guiding element and the radial inner torsion bar is connected in a rotationally-fixed manner to the outer torsion bar and is connected in a rotationally-fixed manner via a coupling to the spring element.

A front lower arm is tiltably supported, in a cantilever manner, by an outer surface of each of side-rails provided in right and left vehicle regions and extending in a vehicle front-rear direction. The front lower arm includes: a lower arm body; an inner pivot provided at an inner end of the lower arm body in a vehicle right-left direction and supported by the side-rail; and an attachment portion to which a lower end of a shock absorber is attached, and which is joined to an intermediate section of a front upper corner portion of the lower arm body. The intermediate section is an intermediate section of the front upper corner portion in the vehicle right-left direction. A ball joint to which a knuckle is connected is attached to an outer end of the front lower arm in the vehicle right-left direction.

A torsion beam of a coupled torsion beam axle may include an external beam having a first cross-section in which an external protrusion of a middle end portion of the external beam is formed to protrude toward upward in a longitudinal direction of the external beam, and external skirt portions are vertically extended along the longitudinal direction at both end portions of the external protrusion; and an internal beam having a second cross-section in which an internal protrusion of a middle end portion in the internal beam is inserted into the external beam to face the external protrusion of the external beam, and internal skirt portions are extended in a vertical direction at both end portions of the internal protrusion, and each external surface of the internal skirt portions and each internal surface of the external skirt portions are surface-bonded in a mutually matched state. A gap is formed between an external surface of the internal protrusion and an internal surface of the external protrusion to form a closed cross-section.

A wheeled work vehicle (1) comprises a forward chassis part (4) and a rearward chassis part (5) pivotally connected about a substantially vertically extending primary pivot axis (7) for steering thereof. A pair of forward ground engaging wheels (29) are carried on a forward suspension unit (32), and a pair of rearward ground engaging wheels (30) are carried on a rearward suspension unit (33). The forward suspension unit (32) is pivotally connected to the forward chassis part (4) by a pair of main forward transverse pivot shafts (63) pivotally coupled to the forward chassis part (4) by corresponding main forward pivot mountings (65). The main forward transverse pivot shafts (63) defines a main forward transverse pivot axis (59) about which the forward suspension unit (32) is pivotal relative to the forward chassis part (4). The forward suspension unit (32) comprises a pair of spaced apart trailing arms (35) which are joined by a torsion shaft (68) of tubular steel, which is rigidly connected to the trailing arms (35). The torsion shaft (68) defines a torsional axis (70), and permits limited upward and downward pivotal type torsional deflection of the trailing arms (35) relative to each other. The rearward suspension unit (33) is substantially similar to the forward suspension unit (32) and is coupled to the rearward chassis part (5) about a pair of main rearward transverse pivot shafts (87) in a similar manner as the forward suspension unit (32) is coupled to the forward chassis part (4).

A vehicle suspension component (16), such as a lower control arm, that includes first and second stamped metal shells (30, 32) and several connection nodes (36, 38, 40) for operably connecting the suspension component to the rest of the vehicle suspension system. The first and second stamped metal shells may be stamped from next generation steel that is lightweight and strong, and are joined together in a clam shell or box-style type design. Each of the connection nodes includes a fixed attachment end (92, 192) and a movable attachment end (94, 194), wherein the fixed attachment end may be sandwiched between the shell connection node portions of the first and second stamped metal shells and welded thereto, whereas the movable attachment end movably or pivotably attaches the vehicle suspension component to the vehicle suspension system.

A fiber-reinforced resin structure body includes a first member and a second member. The first member is made of a fiber-reinforced resin; and the second member is made of a fiber-reinforced resin and forming a closed space by being joined to the first member. One or both of the first member and the second member includes a side wall having two side surfaces located on both sides in a direction of a load loaded on a swing end of the fiber-reinforced resin structure body. A joint joining the first member and the second member together is provided more on an inside than an outer wall surface located on an opposite side to the closed space out of the two side surfaces is.
