A damper assembly includes a main tube disposed on a center axis and defines a fluid chamber for containing a working fluid. A main piston is disposed in the fluid chamber dividing the fluid chamber into a rebound and a compression chamber. A piston rod is attached to the main piston for moving the main piston between a compression stroke and a rebound stroke. An additional piston is attached to the piston rod adjacent to the main piston. The additional piston includes a body having an upper and a lower member defining a groove. A sealing ring is disposed in the groove and being radially expandable in response to a working fluid pressure. The sealing ring includes at least one annular collar extending outwardly from the sealing ring for forming a locking engagement with the upper and lower members to limit the radial expansion of the sealing ring.

A support ring used as part of an air spring assembly, where the support ring provides support for a top cap against radial forces applied by a clamping ring. The support ring is made of a plastic material which is less costly than a metal support ring. The plastic material is a high creep resistance plastic material, which provides increased strength and improved creep resistance, to withstand the compressive radial forces of the clamping ring. Once the support ring is formed, the top cap, which is also made of plastic, is overmolded such that a portion of the top cap is overmolded around the support ring. The high creep resistance plastic material is oriented during the injection molding process around the entire circumference of the support ring, to provide sufficient strength to withstand the radial forces from the clamping ring.

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.

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.

A link arm for connecting a first unsuspended mass to a second suspended mass, and its manufacturing method are provided. In some embodiment the arm 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. In some embodiments, the arm comprises housings to receive a first linkage joint to the first mass, and at least a second linkage joint to the second mass, and comprises: a stiffening portion which comprises a first thermoplastic or thermosetting matrix composite material reinforced with fibers and which comprises a peripheral rim of the arm, and an anti-buckling portion interposed in the stiffening portion and extending from the rim over substantially the entire arm.

A chassis component for a motor vehicle has a core module with at least one first load-conducting element, at least one second load-conducting element and at least one load transfer element connecting the at least one first load-conducting element and the at least one second load-conducting element, and an insert molding. A method for producing the chassis component first of all produces the core module by joining the at least one first load-conducting element and the at least one load transfer element and also the at least one load transfer element and the at least one second load-conducting element, and then overmolds the produced core module.

A slide bearing (1) is provided with an upper case (2) attached to an upper support for attaching a strut assembly to a vehicle body, a lower case (3) which is rotatably combined with the upper case (2) and which forms an annular space (7), and an annular center plate (4) and sliding sheet (5) disposed in the annular space (7). The upper case (2) has a load-transmitting surface (27) constituting part of an upper surface of the annular space (7), the center plate (4) is provided with an annular recess (43) filled with a lubricant, and the center plate (4) has a bearing surface (41) for supporting loads exerted on the load-transmitting surface (27). The sliding sheet (5), which is disposed between the load-transmitting surface (27) and the bearing surface (41), has a sliding surface (51) that slides against the bearing surface (41). The sliding sheet (5) is formed of a thermoplastic plastic, and the center plate (4) is formed from a thermoplastic elastomer having a lower modulus of elasticity than the thermoplastic plastic.

This stabilizer link includes a metal support bar, and ball joints that are provided at both ends of the support bar. Each ball joint includes a ball stud one end of which is fastened to a suspension device or a stabilizer, and which has a ball part at the other end thereof, and a housing that rotatably supports the ball part of the ball stud. The support bar includes: a body part extending in a nearly linear shape, and reinforcement parts each having a nearly annular shape and each provided at both ends of the body part. The reinforcement parts of the support bar are each embedded in the housing so as to surround the ball part.

A leaf spring assembly resiliently supporting a wheel carrier on a vehicle body of a motor vehicle. The leaf spring assembly including first and second spring leaves and a clamp having a clamping part exerting a clamping force whereby the first and second spring leaves are held together by the clamp. A bridging part arranged between the first spring leaf and the clamping part transmits at least part of the clamping force from the clamping part to the first spring leaf bridging the second spring leaf and reducing the clamping force exerted thereon.

The present invention relates to a stabilizer link for automobile suspensions, comprising: a tubular body (1), having at one end a pair of first flattened areas (2, 2) configuring a leak-tight closure of a first inner cavity (9) of the tubular body (1) located between both flattened areas (2, 2); and a first covering (4) made of polymeric material coupled, during the forming process thereof, on the end of the tubular body (1) such that it surrounds the pair of first flattened areas (2, 2), and wherein said covering (4) comprises a first articulation (6).
