A steering system including a plurality of steering devices respectively provided for a plurality of steerable wheels that belong to at least one of a front-wheel side and a rear-wheel side of a vehicle, wherein the plurality of steering devices respectively include a plurality of steering actuators, and wherein each of at least one of the plurality of steering actuators is disposed on an inner side of a corresponding one of side members of the vehicle.

A vehicle suspension component, such as a lower control arm, that includes first and second stamped metal shells and several connection nodes for operably connecting the suspension component to the rest of the vehicle suspension system. The first and second stamped metal shells may be stamped from next generation steel that is lightweight and strong, and are joined together in a clam shell or box-style type design. Each of the connection nodes includes a fixed attachment end and a movable attachment end, wherein the fixed attachment end may be sandwiched between the shell connection node portions of the first and second stamped metal shells and welded thereto, whereas the movable attachment end movably or pivotably attaches the vehicle suspension component to the vehicle suspension system.

A chassis control arm includes a single-piece base body with several hollow chambers. The base body includes a plurality of bearing mounts. A first bearing mount is formed by one of the hollow chambers and traverses the base body to define a first bearing axis which extends in extrusion direction. A second bearing mount in a first end portion of the base body defines a second bearing axis in a direction which deviates from the extrusion direction of the hollow profile. A third bearing mount is positioned in a second end portion of the base body. The base body has a center portion which includes the first bearing mount and is arranged between the first and second end portions. The base body has a first leg extending from the first end portion to the center portion, and a second leg extending from the second end portion to the center portion.

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.

A void bushing for a vehicle suspension is configured to have protrusion parts formed to protrude outwards on a bulge part of an inner pipe. The protrusion parts are located to be disposed in oblique line directions between void portions of an elastic body that is filled between the inner pipe and an outer pipe. In the void bushing, ride comfort characteristics and durability characteristics of a vehicle may be maintained, as they are, under favorable conditions by the void portions. Further the handling response characteristics of the vehicle may be advantageously improved by promoting a rigidity increase through the protrusion parts.

A front suspension apparatus in which a front side of a suspension arm can be cut off from a subframe at the time of a small overlap collision without a complication of structure and formability. A front suspension apparatus in which a lower arm from which a front wheel is suspended is provided, and a front arm portion and a rear arm portion of the lower arm are axially supported by axially supporting portions of a subframe is characterized in that an axially supporting portion of the front arm portion is joined to the subframe at a joined portion extending in a vehicle width direction, a joined portion extending in an up-down direction, and a joined portion extending in a front-rear direction, and a joining strength of a joined portion in the front-rear direction is lower than a joining strength of the joined portion in the up-down direction.

A subframe assembly for a vehicle and a method for manufacturing the same is disclosed. The subframe assembly includes a crossmember, a straight arm, and a side bracket. The crossmember includes an end bracket disposed at an end thereof. The straight arm is received into and metallurgically bonded to the end bracket of the crossmember. The side bracket includes a base, and a rear bracket arm. The base is metallurgically bonded to a side of the straight arm adjacent to the end of the crossmember. The rear bracket arm extends from an end of the base and defines a hole adapted to receive a screw or pin for connecting a control arm of a wheel suspension to the subframe assembly. The rear bracket arm is at least partially received into and metallurgically bonded to the end bracket of the crossmember.

On at least one surface of a structural part, on all or part of a hollow section between outer and inner peripheral borders, is associated at least one cover sheet made of rigid metallic material. The at least one cover sheet is mechanically fixed with the edge of the peripheral borders of the structural part, and covers all or part of inner cavities formed on open sides of the part. The at least one cover sheet has a triple function: to increase the rigidity of the structural part, to absorb shock by deforming in a plane while remaining integral with the part, and to allow reduction of the mass of the structural part and optimization of the mass/performance ratio.

A steering system including a plurality of steering devices respectively provided for a plurality of steerable wheels that belong to at least one of a front-wheel side and a rear-wheel side of a vehicle, wherein the plurality of steering devices respectively include a plurality of steering actuators, and wherein each of at least one of the plurality of steering actuators is disposed on an inner side of a corresponding one of side members of the vehicle.
