Abstract:
A method for the manufacture of a wire wheel of the type comprising a rim and a hub secured to each other by a plurality of spokes. Each spoke includes a stem at the opposed axial ends of which are arranged respective anchorage members capable of being secured respectively to the hub and to the rim. The member for anchorage to the rim is received in a seat fixed on the rim with the capability of limited axial displacement in the seat. The seat is provided integrally on the rim in the form of a substantially tubular appendage thereof and the anchorage member is received in a sealed manner with coupling of the cylinder/piston type in the tubular appendage.
Abstract:
A spoked wheel for a bicycle includes a rim, a hub, a plurality of spokes tensed between the rim and the hub, each provided with a spoke attachment element for attachment to the rim, a plurality of seats, such seats being openings formed in the rim, each for housing one of said spoke attachment elements. The shape and size of the spoke attachment elements and of the seats of the rim are such that: the spoke attachment element is suitable for taking up a first configuration in which its insertion through the seat is possible; and the spoke attachment element once inserted in the seat assumes a second configuration in which it is not possible to remove the spoke attachment element through the seat.
Abstract:
A positioning device includes a sleeve member engaged with one of holes defined in the wheel rim and a base has its shank extending through a passage of the sleeve member. A threaded hole is defined in the shank so that an end of a spoke is threadedly engaged with the threaded hole in the shank. A sealing ring made of non-metallic material is mounted to the sleeve member so as to seal the hole in the rim. The coating of the rim is not scrubbed by any of the parts of the positioning device and the installing processes are easy and can be finished within a short period of time.
Abstract:
The spoked wheel apparatus is symmetrical, is reversible, employs spokes that are threaded on both ends, and is capable of supporting a tubeless tire, without air leaking from the tire. A hub assembly for the wheel apparatus includes two sides, and each side includes a plurality of alternately crossing spokes that are connected between the hub assembly and a wheel rim portion. Each hub side includes an interchangeable and reversible drive dowel assembly capable of receiving a drive sprocket or disc brake. For a hub side, some spokes are connected between outer portions of the hub side to the wheel rim portion, and some spokes are connected between inner portions of the hub side to the wheel rim portion. Alternating pairs of inner and outer spokes come into interference contact midway between the hub assembly and the wheel rim portion, whereby strengthening and stabilizing effects are provided between the interfering spokes.
Abstract:
A spoked wheel includes a rim, at least one spoke and at least one sealing sticker. The rim includes a spoke bed wall with at least one spoke hole therein, a pair of tire-holding flanges extending from opposite edges of the spoke bed wall, a base wall located radially inboard from the spoke bed wall and connected to the flanges. The base wall has an opening corresponding to the spoke hole of the spoke bed wall. The spoke has a nipple portion inserted in the spoke hole of the spoke bed wall of the rim, and a shank portion extending from the nipple portion and through the opening of the base wall of the rim. The sealing sticker is provided to seal the opening of the base wall of the rim and close any gap between the opening of the base wall and the shank portion of the spoke.
Abstract:
A spoke for a wire wheel of the type including a rim and a hub interconnected with one another by a plurality of spokes, each of which includes an end portion arranged to be retained at least in one direction in a seat associated with the rim. The spoke has a bush associated with the end portion for receiving same to define the seat. The bush is arranged to be inserted in a through-hole of the rim.
Abstract:
A spoke wheel including an assembly of spokes and corresponding nipples for connecting a wheel hub and a rim to each other, wherein the nipples are held axially in corresponding seats of the rim by an axial locking assembly including a belt closed in a ring on the rim behind the nipples so as to hold them in the respective seats.
Abstract:
A spoke fastening device includes a spoke fastening hole drilled through a spoke bed of a wheel rim for receiving a head and a stem of a nipple and a collar of a ferrule, the ferrule includes a casing on one end of the collar for engaging with the spoke bed and having an inner peripheral channel for receiving a sealing ring which may make a water tight seal between the nipple and the ferrule and for allowing the nipple to be tilted or inclined relative to the ferrule, the collar includes a peripheral groove for forming two separated cylindrical segments and for allowing the outer cylindrical segment to be flared by the head of the nipple.
Abstract:
A self-sealing automotive spoke wheel nipple includes a spoke nipple and an elastic gasket. The spoke nipple that mounts the spoke into the rim includes a rotational axis, a head, a shank, and a spoke-engaging opening. The head, the shank, and the spoke-engaging opening are concentrically positioned along the rotational axis. The head is adjacently connected to the shank. The spoke-engaging opening traverses into the shank, opposite of the head so that the spoke can be threadedly engaged to the spoke nipple. The elastic gasket is laterally positioned around a shoulder portion of the shank and positioned adjacently to the head. The elastic gasket creates a hermetic connection between the rim and the spoke nipple as the elastic gasket completely seals the spoke opening of the rim during the installation process.
