The disclosure relates to a wheel link for receiving a bearing in a vehicle that comprises a single-piece wheel link body having a first wheel link end, a second wheel link end, and a connecting section that connects the first wheel link end and the second wheel link end. The single-piece wheel link body extends along a wheel link longitudinal axis. A sleeve-shaped eyelet is formed in the first wheel link end. And the first wheel link end is bulged to form a bearing sleeve for the bearing, increasing a diameter of the sleeve-shaped eyelet and a length of the eyelet transversely with respect to the wheel link longitudinal axis beyond the dimensions of the connecting section.

A front lower arm is tiltably supported, in a cantilever manner, by an outer surface of each of side-rails provided in right and left vehicle regions and extending in a vehicle front-rear direction. The front lower arm includes: a lower arm body; an inner pivot provided at an inner end of the lower arm body in a vehicle right-left direction and supported by the side-rail; and an attachment portion to which a lower end of a shock absorber is attached, and which is joined to an intermediate section of a front upper corner portion of the lower arm body. The intermediate section is an intermediate section of the front upper corner portion in the vehicle right-left direction. A ball joint to which a knuckle is connected is attached to an outer end of the front lower arm in the vehicle right-left direction.

The production method disclosed is a method for producing a front axle beam. The production method includes a die forging step and a bending step. The die forging step is a step of forging a steel material with dies to produce a forged product including a rough web part, which is to be formed into a web part, and four plate-shaped rough flange parts protruding frontward and rearward from an upper side and a lower side of the rough web part, respectively. The bending step is a step of pressing at least one specified rough flange part, which is at least one of the four rough flange parts, with a first die to form a bent portion in the specified rough flange part such that the bent portion is bent inward in an up-down direction of the forged product.

In a pressing step, a first forged product is pressed by a first die, and thereby, a second forged product including a rough flange having a thickness-changing portion is produced. The thickness-changing portion includes a front part protruding frontward from a side of a rough web part and a rear part protruding rearward from the side of the rough web part. Each of the front part and the rear part includes a first part, and a second part that is thicker than the first part and is located farther from the rough web part than the first part. In the pressing step, at least a part of the rough flange that is above or below the web part (thick part) is pressed by the first die, whereby the material of the first forged product in the part is caused to flow frontward and rearward, and the thickness-changing portion is formed.

The production method includes a first step, a second step and a third step. In the first step, a steel material is forged by dies, whereby a forged product including a rough web part and four plate-shaped rough flange parts is produced. In the second step, at least one specified rough flange part, which is at least one of the four rough flange parts, is pressed by a first die, whereby a first bent portion bending outward in an up-down direction is formed in the specified rough flange part. In the third step, the edge of the first bent portion is pressed by a second die inward in the up-down direction, whereby the edge is deformed and a second bent portion is formed. In the third step, the edge of the specified flange part is deformed while the edge is kept from deforming in a front-rear direction.

Provided is a vehicle suspension member securing a strength against external force in a vehicle longitudinal direction. A lower arm includes an arm body, a front bush support part, a rear bush support part, a ball joint support part, a first rib, a second rib, and a third rib. The third rib is disposed in a lateral part connecting the ball joint support part to the rear bush support part. An S-shaped rib center curve of the third rib intersects with a straight line at an intersection. |(1S2/S1)|0.2 is satisfied, where S1 is area of a first region defined by the rib center curve and the first straight line, and S2 is area of a second region.

A front suspension device comprises a suspension arm, one end of which has a front-wheel support portion to support a front wheel of a vehicle and the other end of which is positioned on an inward side, in a vehicle width direction, of the front-wheel support portion and has a vehicle-body attachment portion to be attached to a vehicle-body member of the vehicle and a damper supported at a damper support portion which is provided at a portion of the suspension arm which is positioned in the vicinity of the front-wheel support portion at a lower portion thereof and connected to the vehicle-body member at an upper portion thereof. The damper support portion of the suspension arm has a breakage ease portion to cause breakage of the suspension arm.

An automobile undercarriage component has at least three elongated arms, each including a web and a rib having an inner wall surface. One of the three elongated arms is a first arm having a first one of the ribs and at least one of the three elongated arms is a second arm having a second one of the ribs. For each of the second ones of the ribs, the leading end of the respective second one of the ribs has a width in the direction parallel to the plane of the web and transverse to the direction of elongation of the arm which is narrower than the width of a leading end of the first one of the ribs, as an inner wall surface is disposed closer to an opposing outer wall surface in the respective second one of the ribs as compared to the first one of the ribs.

A fastening arrangement of a vibration damper of a vehicle includes a rubber bearing with a first bush and a second bush, a fastener where via the fastener one of the first bush and the second bush of the rubber bearing is fixed in three degrees of longitudinal freedom with regard to a wheel support of the vehicle or the body of the vehicle, and a measure disposed on the second bush and on the wheel support or on the body of the vehicle where via the measure a degree of rotational freedom of the second bush about an axis of the fastener is blocked by a positively locking block. The positively locking block is formed by a convexly curved cylinder segment of the second bush and a concavely curved cylinder segment of the wheel support or the body of the vehicle that are engagable into one another.

In accordance with one aspect of the present disclosure, a suspension strut for use on a work machine is provided. The suspension strut may have a forged one piece cylindrical inner housing that includes a hollow rod which forms a circumferential piston at an open end and a lower clevis at a closed end of the hollow rod. The suspension strut may further have a forged one piece cylindrical outer housing that includes a hollow barrel having an interior and an exterior surface, a closed end that forms an upper clevis, an open end, and a port on an outside surface of the hollow barrel. Further, the inner and outer housing may be coupled by a disk shaped end cap attached to the open end of the hollow barrel having an inner diameter that is slideably engaged with an outer surface of hollow rod.
