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.

A dust cover is configured to cover an outer side of a damper extending in a predetermined direction. The dust cover includes bellows portions and a flange portion. The bellows portions are inclined alternately toward a radially outer side and a radially inner side in an axial direction. The flange portion extends radially outward from a cylindrical portion of the dust cover. The flange portion protrudes radially outward from the cylindrical portion of the dust cover by a dimension larger than a height dimension in a radial direction between a radially inner end and a radially outer end of each of the bellows portions. A thickness of the flange portion is larger than a thickness of the radially outer end of each of the bellows portions.

A linking arm assembly incorporating an improved connection between an elongated rod portion and an engagement element such as a ball stud or the like adapted to join the linking arm to another structure. The linking arm assembly may incorporate an improved ball and socket connection. The socket may include an arrangement of flexible rib elements that are compressed when the ball stud is inserted so as to bias against the ball during use.

A cover is disclosed for a chassis control arm which includes at least one bearing mount for a control arm bearing. The cover is formed separately from the chassis control arm and covers in the installed state at least part of the underside of the chassis control arm. Arranged on the cover is an extension which is intended as buffer and extends from the cover in the direction of the control arm bearing.

A strut-type damper is disclosed. The damper has a shock absorber having a housing with a telescoping piston rod, a coil spring, an upper spring seat operably coupled to a distal end of the piston rod, and a lower spring seat operatively coupled to the housing. The upper and lower spring seats capture the coil spring therebetween. The lower spring seat has a base portion having an opening for receiving the housing and is fixedly securable to the housing. A generally circumferential wall portion extends from the base portion and forms a catcher for catching a broken portion of the coil spring if the coil spring fractures. An impact absorbing structure is formed on the lower spring seat adjacent both of the catcher and the base portion, and is configured to be crushed in the event of a fracture of the coil spring.

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.

A wheel carrier device for a vehicle, with at least one wheel carrier which has at least one bearing point at which at least one wheel bearing is to be mounted for rotatably mounting a wheel hub, wherein the wheel carrier is at least partially surrounded on the outer circumference by at least one thermal insulation element.

A sleeve for an air spring for a vehicle includes at least an upper sleeve and a lower sleeve. An upper circumferential portion of the upper sleeve is coupled to a top mount, a lower circumferential portion of the lower sleeve is coupled to a piston portion, and one of the upper sleeve and the lower sleeve is formed to have different thicknesses for each section along a longitudinal direction.

A sleeve used as an air spring for a vehicle according to an example embodiment of the present disclosure, includes: at least an upper sleeve and a lower sleeve, in which an upper circumferential portion of the upper sleeve is coupled to a top mount, a lower circumferential portion of the upper sleeve is coupled to an upper circumferential portion of the lower sleeve, a lower circumferential portion of the lower sleeve is coupled to a piston portion, and one of the upper sleeve and the lower sleeve is configured to encompass an area where a lobe is formed.
