[Object] Damage to a surface of a resin bush caused by press-fitting is prevented even when a configuration for positioning during welding is added.

[Solving Means] A rolled collar (40) is a steel rolled collar into which a resin bush (90) is pressed-fitted, and which is joined to a joining member by welding. The rolled collar includes a main body part (50) formed in a hollow cylindrical shape, and a clinch part that joins both end surfaces of the main body part together by fitting. The rolled collar includes a notch part (70) formed by cutting off a portion of an annular edge (53) in the main body part. Here, a convex jig determining a position of the main body part at a time of welding is fit into the notch part. The rolled collar includes a cavity part (80) formed to be hollow from an inner circumferential surface side on a wall surface around the notch part to form a clearance (81) between the press-fitted resin bush and an edge portion (71) of the notch part on the inner circumferential surface side.

The present disclosure relates to a suspension apparatus for a vehicle, the suspension apparatus including an axle carrier to which a wheel is rotatably coupled, a torsion beam axle having a trailing arm coupled to the axle carrier, the torsion beam axle being disposed in a width direction of a vehicle, a spring lower pad coupled to the axle carrier and having a bump stopper, a spring seated on the spring lower pad, and a shock absorber coupled to the axle carrier and disposed to be inclined toward a rear side of the vehicle.

A trailing arm bush may include a cylindrical outer pipe, an inner pipe inserted to a central portion of the outer pipe at an interval, a first bush rubber unit, a second bush rubber unit and a third bush rubber unit that connect between an inner peripheral surface of the outer pipe and an outer peripheral surface of the inner pipe, respectively, a hollow void part formed between the inner peripheral surface of the outer pipe and the outer peripheral surface of the inner pipe, and a stopper attached to the inner peripheral surface of the outer pipe and disposed among the first bush rubber unit, the second bush rubber unit and the third bush rubber unit.

A chassis arrangement (10), in particular for utility vehicles (1), with at least one axle (3) that extends transverse to the travel direction and carries wheels (4). Movement of the axle (3) is damped by vibration dampers (11) provided with end sections (15), and with at least one stabilizer assembly (12) that has two longitudinally extending sections (13) and a transverse section (14) that connects the longitudinally extending sections. An end section (15) of the vibration damper (11) is held directly on and is connected to the stabilizer assembly (12) on an extension (16, 17) of the transversely orientated section (14) beyond the longitudinal section (13).

A twist beam axle for a motor vehicle, having two trailing arms which are connected by a torsion profile, and the torsion profile is integrally joined at its longitudinal end sections to the trailing arms by a weld seam, and the torsion profile has a relief bead in its respective longitudinal end sections in the area of the weld seam, and the relief bead has a longitudinal extension and is oriented transversely to the course of the weld seam in the direction of its longitudinal extension.

A torsion axle assembly for supporting of a vehicle body on an undercarriage, including an elongated inner member having an inner member longitudinal axis; a torsion arm interconnected with the elongated inner member and the undercarriage; an elongated enclosure interconnected with the vehicle body and having an interior space; and resilient material residing within the interior space to support the elongated inner member within the interior space, such that the inner member longitudinal axis resides at an unloaded camber angle to an elongated enclosure longitudinal axis when none of the weight of the vehicle body is borne by the torsion axle assembly and at a loaded camber angle when the weight of the vehicle body is borne by the torsion axle assembly, such that the unloaded camber angle is greater than the loaded camber angle. A vehicle having such a torsion axle assembly and a method are disclosed.

A twist beam axle for a motor vehicle, having two trailing arms which are connected by a torsion profile, and the torsion profile is integrally joined at its longitudinal end sections to the trailing arms by a weld seam, and the torsion profile has a relief bead in its respective longitudinal end sections in the area of the weld seam, and the relief bead has a longitudinal extension and is oriented transversely to the course of the weld seam in the direction of its longitudinal extension.

A vehicle comprising: a vehicle body; first and second wheel assemblies each having a rotation axis; first and second suspension linkages, each suspension linkage coupling a respective wheel assembly to the vehicle body to permit motion of the rotation axis of that wheel assembly relative to the vehicle body; a cross-vehicle spring having a first attachment point coupled to the first suspension linkage and a second attachment point coupled to the second suspension linkage; and a first active link coupling the first attachment point to the first suspension linkage, the first active link being configured to have: (i) a first mode in which the first active link permits motion of the first suspension linkage relative to the first attachment point to prohibit the cross-vehicle spring from constraining motion of the first and second suspension linkages; and (ii) a second mode in which the active link fixes the motion of the first suspension linkage relative to the first attachment point so that the cross-vehicle spring constrains motion of the first and second suspension linkages during common motion of the first and second suspension linkages.
