There is provided a method of manufacturing a suspension arm for a vehicle. The method includes a preform forming operation of forming a preform as a preliminary molding object for forming the suspension arm for a vehicle; and a main-molding-object forming operation of hot-pressing the preform to form a main molding object for forming the suspension arm for a vehicle. The preform formed in the preform forming operation may be formed in a shape corresponding to a shape of the main molding object, and may be formed in a shape offset inward from an outer shape of the main molding object by a predetermined dimension.

There is provided a suspension arm for a vehicle used in a suspension device of a vehicle. The suspension arm may include: a body portion constituting a basic body of the suspension arm; and a plurality of mounting portions configured to connect the suspension arm to a wheel-side member or a vehicle-body-side member. At least one of the plurality of mounting portions may be configured to include a bushing coupling portion and a fastening portion formed to extend from the bushing coupling portion to one side, such that the fastening portion may be coupled to a coupling portion provided on one side of the body portion in surface-contact with state.

An air-suspension module for a rigid axle including an air-bellows mount and an air-bellows module supported on the air-bellows mount in the operational state of the air-suspension module, the air-bellows module having an air-suspension bellows designed to change its shape and a supporting body connected to the air-suspension bellows, one of the components of the air-bellows mount and the supporting body having a coupling projection protruding along a virtual projection path, which engages with a coupling recess formed at the respectively other component along the projection path, a translatory relative movement of the supporting body being physically limited relative to the air-bellows mount, orthogonally with respect to the projection path and in a direction along the projection path; one of the components of the air-bellows mount and the supporting body having a latching body and the respectively other component of the air-bellows mount and the supporting body having a latching recess such that the latching body is in a form-locking latching engagement with the latching recess, so that a translatory relative movement of the supporting body relative to the air-bellows mount is physically limited in the two opposite directions along the projection path.

A suspension device for a vehicle, including a spring-absorber unit constituted by a shock absorber and a suspension spring that are formed as one unit, the shock absorber including a cylindrical housing, a piston disposed in the housing, and a piston rod that is connected at a basal portion thereof to the piston and that extends from the housing, the suspension spring being a coil spring through which the shock absorber passes, wherein one end portion of the suspension spring is capable of being supported by the housing of the shock absorber, and the other end portion of the suspension spring is capable of being supported by a distal portion the piston rod of the shock absorber while the suspension spring is receiving a tensile load.

A double-wishbone type of suspension device for a vehicle comprises a forked-shaped upper arm, a forked-shaped lower arm, and a connecting rod which connects a front-side arm portion of the upper arm and a rear-side arm portion of the lower arm, wherein the connecting rod comprises an upper rod which is rotatably connected to the upper arm, a lower rod which is rotatably connected to said lower arm, and a resilient bush which connects the upper rod and the lower rod in an expandable manner in an axial direction.

Systems are provided for suspensions that deliver desirable wheel kinematics at prescribed conditions. A system includes a vehicle body structure with an engine cradle, and an associated wheel assembly. A suspension system links the wheel assembly with the engine cradle, and includes a link coupled with the engine cradle and coupled with the wheel assembly. A joint at the link includes a flange that has an opening, an edge, and at least one undercut defined in edge of the flange. The joint allows release of the wheel assembly from the engine cradle by designed tearing between the opening and the at least one undercut. The release is initiated only under loads above a select threshold at the joint, to provide select kinematics of the wheel assembly for specific operational cases.
