A chassis of a motor vehicle, having at least one part that consists of a metal material and absorbs or transmits forces, at least one tape-shaped reinforcing element that consists of a fiber-reinforced metal matrix being applied to the surface of the part by thermal joining in the broadest sense. Chassis, which are of different motor-vehicle types in terms of their weight and/or their drive power and the same part, in terms of its geometric dimensions, that absorbs or transmits said forces, are characterized in that, when used in a motor-vehicle type with a higher weight and/or a greater drive power, a reinforcing element is applied to at least one surface portion, forming a load path, of this part, which reinforcing element is either not provided at all or is provided in a smaller size in a different motor-vehicle type with a lower weight and/or lower drive power.

It is herein described an oscillating arm for a motor-vehicle suspension having a first rod element and a second rod element. The second rod element is a half-shell rod that provides a cavity. The oscillating arm also comprises at least one insert, made of plastic or fiber-reinforced composite material, which fills the cavity of the half-shell rod.

A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device includes an upper annular bearing member and a lower annular bearing member in relative rotation. The lower annular bearing member having a body provided with an embedded stiffening insert. The device further provides a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. A radial flange of the damping element prevents separation from the lower side of the radial flange of the lower cap.

The present disclosure relates to a method of manufacturing a vehicular hybrid suspension arm and a hybrid suspension arm manufactured using the same. The method of manufacturing a hybrid suspension arm includes preparing an assembly of a ball stud and a bearing; preparing a suspension arm body; attaching a ball joint pipe and bush pipes to the suspension arm body; manufacturing a suspension arm main body by inserting the assembly of the ball stud and the bearing into the ball joint pipe; inserting the suspension arm main body into a mold in which a plurality of fixing pins are formed; injecting an insert molding into a ball joint portion comprising the ball joint pipe and the ball stud in a direction of an upper surface of the ball joint pipe through the mold; and inserting and assembling bushes into the bush pipes.

A lightweight suspension assembly for a vehicle includes a suspension upright or knuckle provided with a bearing connection interface for receiving at least part of a wheel bearing, and with a first molded portion made of a first polymeric material; the assembly further includes at least one arm having a second molded portion made of a second polymeric material, and at least one joint member coupling the arm to the suspension upright/knuckle in such a manner to allow a relative rotation between the arm and the suspension upright/knuckle about at least one rotation axis (B); the first and second molded portions are arranged onto a first surface and, respectively, a second surface of the joint member, in such a manner that the first and second molded portions are coupled in a non-releasable manner to the joint member.

A disclosed front axle beam includes a beam section. The beam section includes a first flange part, a second flange part, and a web section connecting the first flange part and the second flange part. The web section includes a varying-slope section that includes a plurality of first slope sections and a plurality of second slope sections. Each of the plurality of first slope sections inclines in one direction with respect to the vehicle-height direction in a cross section perpendicular to the longitudinal direction. Each of the plurality of second slope sections inclines in the opposite direction to the one direction with respect to the vehicle-height direction in a cross section perpendicular to the longitudinal direction. The first slope section and the second slope section are located in an alternate manner along the longitudinal direction. In this way, the rigidity of the front axle beam can be increased.

A suspension assembly for a vehicle may have a first end for pivotal mounting to a structural member of the vehicle and a second end opposite the first end for attachment of a damping arrangement and a stub axle. The suspension assembly may include first and second shell components that are welded together to form a substantially hollow body between the first and second ends.

The present disclosure provides a hybrid suspension arm for a vehicle, the hybrid suspension arm having the strength required for a vehicle while being lightweight and having excellent durability. The hybrid suspension arm for a vehicle according to one embodiment of the present disclosure comprises: an arm body comprising aluminum; and an insert molding part made of plastic material which is insert-molded on the arm body and coupled thereto.

The present disclosure provides a hybrid suspension arm for a vehicle, having excellent durability. A hybrid suspension arm for a vehicle according to one embodiment of the present disclosure comprises: a suspension arm body which is made of metal material and comprises a top plate part and two sidewall parts extending downward from the top plate part to be open downward; and an insert molding which is made of plastic material and is formed by being insert-molded in the suspension arm body, wherein a thickness of at least a portion in the portion of the insert molding that comes in contact with the top plate part and the sidewall parts is in the range of 2 mm to 3 mm.

A hybrid arm according to an embodiment of the present disclosure may include: a first body made of a metal material and formed with a plurality of end portions; a second body formed so as to fill an inner side of the first body by being insert-injection-molded to the first body; and a ball joint formed integrally at a first end portion among the plurality of end portions of the first body. The ball joint may include: a reinforcement member coupled to the first end portion; a bearing member formed with a space therein; a ball stud including a ball rotatably inserted into the space of the bearing member and a rod extending upward of the ball; and a housing interposed between the reinforcement member and the bearing member and formed integrally with the second body.
