A suspension strut fork that has an upper portion which is constructed in an integral, materially uniform manner in the form of a suspension strut receiving member. Members and fork arms protrude therefrom in an integral, materially uniform manner. A gap is provided between the members. Via this gap, the members can be moved toward each other so that a resilient and/or damper element which is arranged in the suspension strut receiving member is securely clamped.

A gas-charging and flanging machine (10) includes a sealed chamber (13a). The gas-charging and flanging machine is used for carrying out, inside the sealed chamber, charging of a gas into a workpiece (20) and flanging of the workpiece (20) by spinning and pressing. The gas-charging and flanging machine charges a gas into a workpiece and flanges the workpiece on the same machine such that production efficiency can be improved.

The present invention provides a method for manufacturing a torsion beam, the method comprising: a planarization step, in which a protruding portion of an upper mold presses the opposite end portions in the width direction of the blank to be plastically deformed to be flat while the opposite end portions in the width direction of the blank are supported by a side cam to face each other; a welding and bonding step for bonding the planarized opposite end portions in the width direction of the blank via welding; and a quenching step for heating the welded and bonded blank within a range of 900 to 970° C. for a retaining time within a range of 1 to 20 minutes and for cooling down the blank in a treatment liquid including at least one of water and oil in a range of 20 to 90° C.

A method of manufacturing a vehicle suspension component includes inserting a cover body into an aperture of a housing, the cover body being disposed about a central axis concentric with the aperture of the housing, the cover body having a convex side and a concave side and an outer perimeter disposed about the central axis, the cover body defining a threaded bore concentric with the central axis, and deforming the cover body into retaining engagement with the housing by pressing against the convex side until the cover body is at least partial deformed and the outer perimeter is expanded compared to a pre-deformed state of the cover body.

To realize a method for manufacturing a hub unit bearing capable of increasing the processing efficiency of a staking portion. An axial inner end portion of a hub ring 22 is processed into a staking portion 26 by rotating a die 31 around a reference axis C in a state in which the die 31 having a rotation axis α inclined with respect to the reference axis C is pressed against the axial inner end portion of the hub ring 22 under a condition that the hub ring 22 is disposed so that a center axis of the hub ring 22 is coaxial or parallel to the reference axis C and the hub ring 22 is supported to be radially movable.

A method for assembling a damper with a device includes inserting a floating piston into a cartridge, filling a region of the cartridge with oil, inserting a piston-rod assembly into the cartridge, inserting a rod guide into the cartridge, coupling a damper tube to the cartridge, supplying a gas into the damper tube via a first end of the damper tube, transferring the floating piston, the piston-rod assembly, the rod guide, and the oil from the cartridge to the damper tube through the first end of the damper tube, and securing the rod guide to the damper tube.

A control arm assembly mechanism includes: a workbench having thereon a holder; a vertically pressing device disposed above the workbench and including a moving arm capable of moving toward and away from the holder; and two transversely pressing devices flanking the workbench and each including a moving arm capable of moving toward and away from the holder. The control arm assembly mechanism operates in such a manner to compress transversely and vertically a bushing placed on the workbench and thereby fit the bushing into a control arm.

A system and method for manufacturing a top mount for a vehicle suspension includes providing a top mount body having a bushing opening and a plurality of stud holes, a plurality of knurled studs, and a bushing having a thermoplastic outer shell, a rubber core, and a central washer. The knurled studs are inserted in the stud holes of the top mount body. Then, substantially simultaneously, a pressure is applied to the knurled studs to press the knurled studs into the top mount body to crimp the knurled studs in the stud holes of the top mount body, and to insert the bushing into the bushing opening of the top mount body.
