An automobile undercarriage component is provided with a web and a rib. The rib is configured so as to comprise a first section that is a section having the widest width and a second section that has a narrower width than the first section, and the second section having a narrower rib width than the first section as a result of an inner wall surface of the second section that is continuously formed from the web being provided so as to be adjacent to a facing outer surface wall.

Provided is a suspension arm manufactured by casting. The suspension arm includes a processing reference hole formed in the casting. The processing reference hole is formed to be elongated in a direction of bending of the suspension arm that occurs in a shaping step. A recess is formed which has one end thereof communicating with the processing reference hole and another end thereof being open to an outer side.

Provided discloses an integrated axle assembly and structural assembly. The integrated axle assembly comprises an axle tube assembly extending in a first direction; a front support arm extending circumferentially from the axle tube assembly in a second direction perpendicular to the first direction for attachment to the frame; a rear support arm extending circumferentially from the axle tube assembly in a third direction away from the second direction for mounting a resilient assembly; and a brake base plate extending in a peripheral direction from the circumference of the axle tube assembly; the axle tube assembly, front bracket arm, rear bracket arm and brake base plate are molded in one piece, which improves the assembly efficiency.

A control arm for the rear wheel suspension of a car where the control arm includes a cup-shaped spring mount with branches projecting from the spring seat. The branches may be designed as closed channels or U-shaped channels. In the upper part of the control arm there are flanges projecting from each side thereof. The flanges include a reinforced area around the spring seat. The cup-shaped spring seat is reinforces with wedges on the inside thereof. The spring seat and branches form a stiff frame structure. Also described is a method for manufacturing the control arm by forging.

A connection bridge device is suggested for connecting a multipoint link to a vehicle axle, particularly a multipart vehicle axle. The connection bridge device comprises at least one base body for receiving and dissipating forces and/or torques transmitted between the vehicle axle and the multipoint link, at least one axle fastening unit for fastening the base body to the vehicle axle, and at least one link coupling unit for coupling the base body to the multipoint link, which link coupling unit is intersected by a main extension plane of the base body.

A damper assembly includes a tubular member including a sidewall and a shoulder. The damper assembly includes a rod and a piston coupled to the rod. A secondary piston has a second contact surface, an opposing second surface, an inner cylindrical face defining a central aperture that receives the rod, and an outer cylindrical face. The opposing second surface includes one or more surface grooves, extending between the inner cylindrical face and the outer cylindrical face along the opposing second surface, and one or more bypass orifices disposed about the body member. The bypass orifices extend along the inner cylindrical face between the second contact surface and the opposing second surface. The secondary piston defines a channel extending between the inner cylindrical face and an outer periphery of the body member. The channel and bypass orifices form a fluid flow path when the piston contacts the secondary piston.

A steering knuckle casting 20 includes a plan portion 22 and a product portion 23 formed along a flow of molten metal 21. The product portion 23 includes an intermediate portion 26, a first fastening portion 27 integrally formed at one end of the intermediate portion 26, a second fastening portion 28 integrally formed at the other end of the intermediate portion 26, and a first rib 31 and a second rib 32 integrally formed in the intermediate portion 26 to extend from the first fastening portion 27 to the second fastening portion 28. The first rib 31 and the second rib 32 are not parallel to each other, and are disposed in a V shape such that a rib spacing W1 on a first fastening portion 27 side is narrower than a rib spacing W2 on a second fastening portion 28 side.
