A suspension bearing unit for a motor vehicle, comprising an upper cup, a lower cup and a bearing interposed between the upper cup and the lower cup in rotation in relation to each other about a principal axis. The suspension bearing unit also comprises at least one seal in a hollow housing provided on one face of a first element from among the lower cup and the upper cup. The hollow housing comprises a plurality of protruding ribs spaced apart circumferentially, the ribs protruding into the base of the seal.

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.

Vehicle top suspension mount comprising an anti-vibratory block housed in casing. The casing may comprise at least one securing element movable between an assembly position and a securing position. The securing element may be configured to block, in the securing position, the vehicle top suspension mount in relation to a vehicle body when the vehicle top suspension mount is joined to said vehicle body.

A suspension system for a vehicle is capable of preventing a spring from completely escaping from a spring pad when rebound additionally occurs in a full-rebound state during driving of the vehicle and thus the spring is extended beyond the extendable range thereof (or the free height thereof).

A four-point link (1) for a wheel suspension of a vehicle, having a core element (2), a thread (3) and four bushings (6). The thread (3) is pre-impregnated with a resin. The core element (2) has a torsional element (4) and four supporting arms (5) integrally connected to the torsional element (4). A bushing (6) is arranged, on each respective distal end of the supporting arms (5), for holding a respective bearing element. The core element (2) and the respective bushings (6) are at least partially wrapped with the thread (3) in order to connect the bushing (6), in each case, to the thread (3) at least in a non-positive manner. In addition, a method for producing the above-mentioned four-point link (1).

A hybrid lower arm and a hybrid upper arm include an arm body made of a metal material, and an insert injection-molded integrally with the arm body so that the insert is inserted into an inside of the arm body. The arm body has a weight ratio of 50% or more and 90% or less with respect to the total weight of the hybrid lower arm or the hybrid upper arm, thus achieving the rigidity increase as well as the weight reduction in the lower arm and the upper arm of a suspension system.

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 vehicular hybrid suspension arm includes a suspension arm body made of a steel material, and an insert molding inserted into and coupled to the suspension arm body, providing a suspension arm having reduced weight and high rigidity.

Provided is a method for manufacturing a ball joint including a ball-seat molding step for forming a ball seat assembly by using, as a core, a ball section of a ball stud, the ball section of which is integrally provided in advance at one end portion of a stud section, and insert-molding a ball seat made of resin to cover at least a portion of the ball section present on an opposite side to the stud section, and a housing molding step for insert-molding a housing made of resin by using, as a core, the ball section partially covered by the ball seat of the ball seat assembly.

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.
