A wheel includes a rim and a wheel center with several spokes with at least one butt strap. The at least one butt strap protrudes from a radially outer end of the spokes. The rim includes at least one opening arranged corresponding to the at least one butt strap. The at least one butt strap extends across the related opening in the rim and is attached to the outside of the rim.

Method for manufacturing a vehicle wheel, comprising the following steps: providing a rim made of metal sheet, providing a disc made of metal material, comprising a cover part and a connection part, protruding axially from the cover part, wherein on the connection part is obtained a plurality of recesses, distributed in the circumferential direction of the connection part, interference-fitting the connection part of the disc to a radially inner surface of the rim, and applying a magnetic pulse to deform areas of the rim respectively superimposing the recesses of the connection part, so that the disc is held in rotation and axially by said deformed areas of the rim.

A method for producing a product including a composite fiber part and a second part, wherein the second part includes a carrier part, wherein the carrier part is a replica of a press tool configured to be heated and to apply a pressure, the method including applying, in a non-cured state, the composite fiber part on the carrier part, arranging the carrier part including the composite fiber part on the press tool, curing the composite fiber part on the carrier part, and removing the product from the press tool, wherein after removal from the press tool the composite fiber part and the carrier part constitutes together at least a part of the finished product. Also disclosed is a composite fiber product including a composite fiber part and a second part.

A spoke has a carbon rod and at least one connecting unit. The carbon rod is made of a composite material containing thermoplastic resin and carbon fibers and has at least one blocking portion. Each one of the at least one connecting unit has a tube mounted on and around the carbon rod and blocked by a corresponding one of the at least one blocking portion. The carbon rod is heated and shaped to form the blocking portion. The spoke in accordance with the present invention blocks the connecting unit by the blocking portion to promote a connection stability of the spoke.

Axial relative movement of an auxiliary member (30) and a hub body (22z) is performed, the hub body (22z) and an inner race (21) are combined with each other in an axial direction, and a part of the hub body (22z) deformed by a blade (33) of the auxiliary member (30) is disposed inside an engagement concave portion (26) of the inner race (21).

An indentation tool includes an installation axis, a radially oriented indentation axis, and a defined reserved space for an indentation site of a cylindrically-shaped structure, as well as a base for installing onto the structure, and an elongate punch for indenting it at its indentation site. The reserved space is spaced apart from the installation axis, and has the indentation axis passing through it. The base extends along the installation axis, and is configured for coaxial installation onto the structure, whereby its indentation site occupies the reserved space. The punch is spaced apart from the installation axis, and is supported by the base for movement along the indentation axis between a home position, in which the punch vacates the reserved space, and an indentation position, in which the punch, leading with an indentation tip, reaches into the reserved space to indent the structure at its indentation site.

Self-locking nipple for attaching wheel spoke to wheel part. The self-locking function of the nipple is created by deforming the nipple body in a rotationally symmetrical way and over a predetermined axial distance, such that such a narrowed part is created in the internal screw-thread of the nipple which is rotationally symmetric with respect to the longitudinal axis of the nipple and extends over only one to two windings of the internal screw-thread.

Axial relative movement of an auxiliary member (30) and a hub body (22z) is performed, the hub body (22z) and an inner race (21) are combined with each other in an axial direction, and a part of the hub body (22z) deformed by a blade (33) of the auxiliary member (30) is disposed inside an engagement concave portion (26) of the inner race (21).

A method of manufacturing a rolling bearing unit for supporting a wheel includes detecting a current value flowing through an electric motor (19) configured to drive a roll (22) and determining a time to terminate a caulking process on the basis of the detected value when a caulking section (13) is formed by pressing the roll (22), inclined with respect to a central axis of a hub main body (7) and supported in a rotatable state about a central axis of the roll, against a cylindrical section (12), installed on an inner end portion of the hub main body (7) in the axial direction, while the roll (22) is rotated about the central axis of the hub main body (7).

Provided is a method of manufacturing a wheel bearing apparatus including an outer ring, a rolling element, a hub spindle, and an inner ring member. The hub spindle is disposed inward of the outer ring in a radial direction via the rolling element. The inner ring member fitted on the hub spindle and is secured by a clinched portion. The clinched portion is formed by clinching a spindle end portion of the hub spindle outward in the radial direction. The method includes: plating a predetermined area including the spindle end portion of the hub spindle; removing a plating of the spindle end portion of the predetermined area; and clinching the spindle end portion to form the clinched portion after removing the plating.
