The disclosure relates to a motor vehicle control arm, like a wishbone, having an integral main body configured in a materially integral manner. A first bearing receptacle is connected to the main body. The main body has a first end portion having a second bearing receptacle, and a second end portion having a third bearing receptacle. The main body comprises a central portion. Said central portion connects the first and the second end portion. The central portion is configured as a cavity profile. The second and the third bearing receptacle are configured integrally and in a materially integral manner from the main body.

A four-point link for a wheel suspension of a vehicle includes a core element, a filament and four bushings. The filament is pre-impregnated with a resin. The core element further has a torsional element and four support arms connected integral with the torsional element. The core element and the respective bushing are at least partially wrapped by the filament. The respective bushing for receiving a respective bearing element is arranged at a respective distal end of the respective support arm. The respective bushing has at least one anchor element, and at least one undercut is formed between the at least one anchor element and the bushing, and the core element engages in the undercut for connecting the bushing to the support arm of the core element by positive engagement.

The objective of the present invention is to improve the rigidity of a vehicle knuckle made from an aluminum alloy with respect to a force directed from the outside to the inside in the width direction of a vehicle. A vehicle knuckle (11) is provided with a bearing support portion (111), a knuckle upper portion (113) and a knuckle lower portion (112). With the vehicle knuckle (11) in a position fitted to a vehicle main body, the knuckle upper portion (113) has a shape in which, if the knuckle upper portion (113) is divided equally into five or more regions in a vertical direction, and the center of the bearing support portion (111) is fixed and a horizontal load F is applied to a knuckle upper end portion (115) from the outside toward the inside in the width direction of the vehicle, the minimum value of a value obtained by dividing the strain energy in each of the five or more regions other than a first region (11A) by the mass of the corresponding region is at least equal to 0.70 times the maximum value thereof.

A control arm and a method of manufacturing thereof is disclosed. The control arm is made of an aluminum extrusion profile with a first end section, a second end section, and a middle section, which connects the first and second end sections. The control arm includes a base, two side walls, which are angled substantially perpendicular therefrom and which are spaced apart from one another on the longitudinal side, with a height H, and flanges, which are angled substantially perpendicular from the side walls at their free end. The first end section includes a first connecting region, the second end section includes a second connecting region, and the middle section includes at least one third connecting region.

a multipoint control arm having a metallic base body (6), with three or more joint holding openings (11, 12, 13), and a plurality of joints (3, 4, 5) which, in each case, are seated in a respective one of the joint holding openings (11, 12, 13). A first joint, or at least one first joint (3) has a joint housing (19) inserted into a corresponding joint holding opening (11) and an inner joint portion (20) which is fitted and able to move in the joint housing (19) and extends out of the latter. The metallic base body (6) and the joint housing (19) of the first joint (3) are both embedded in a casing body (7), made from a fiber-reinforced plastic.

An elastic member is an elastic member formed of a wire having a cross section that is substantially circular, the cross section being orthogonal to a longitudinal direction, and the elastic member being expandable and contractible in a predetermined direction; and including: a first alloy portion that is made of an aluminum alloy having a tensile strength larger than 950 MPa and equal to or less than 1100 MPa at room temperature; and a second alloy portion configured to cover the first alloy portion, the second alloy portion having a thickness in a radial direction smaller than a radius of the first alloy portion, and being made of an aluminum alloy having a tensile strength of 100 MPa to 650 MPa at room temperature.

A linking device links an aluminum side rail of a vehicle body structure and an end of a control arm that includes a cylindrical linking ring. The device remarkably includes an aluminum casting including an upper surface attached under the side rail, and a side wall from which emerges, perpendicular to an outer side surface, at least one first control arm interface including a pair of tabs separated from one another by an air-gap value greater than the length of the cylindrical ring, in order to set the end of the control arm.

In an embodiment, the present invention provides a stop device for limiting a vertical spring deflection of a motor vehicle leaf spring that is mounted on an axle member, the stop device including: a stop which limits a vertical movement of the leaf spring; a support structure for supporting and mounting the stop on a vehicle support; and a guiding device for receiving and guiding at least one of a cable, a line, and/or a holder. The guiding device is fastened to the support structure.

A stabilizer is provided with a restriction ring connected to a torsion portion at a connection portion adjacent to a bush. The restriction ring has a body, a female portion, a male portion, and a welded portion. The female portion has gripping portions with a spacing therebetween decreasing in the direction away from a valley bottom portion. The male portion has a neck portion, an expansion portion, and a contraction portion. The welded portion covers at least the range of the contraction portion and the valley bottom portion and melts in the plate thickness direction from the outer peripheral surface.

A composite part for an air spring component of a motor vehicle includes a first element made of a first material and a second element made of a second material. The second element at least partially surrounds the first element. In the air spring component, the composite part can be bonded to at least one second component in an adhesive-bonded manner.
