A laced wheel manufactured from a one-piece casting, including both the hub portion and the rim portion. After casting and machining spoke interfaces, the hub and rim portions are separated and wire spokes are assembled.

A system for manufacturing a wheel includes a cope mold portion with internal cope mold walls and a drag mold portion with internal drag mold walls. The internal cope mold walls and internal drag mold walls define at least in part perimeter boundaries of a wheel cavity. The wheel cavity includes a cavity center portion configured to form a wheel center portion of a wheel after solidification of a molten alloy in the cavity center portion, a cavity plate portion configured to form a wheel plate portion of the wheel after solidification of a molten alloy in the cavity plate portion, and a cavity flange portion configured to form a wheel flange portion of the wheel after solidification of a molten alloy in the cavity flange portion. The system includes a chill component positioned within the wheel cavity adjacent the cavity flange portion. The chill component is configured to provide directional solidification from the cavity flange portion toward the cavity plate portion of molten alloy in the wheel cavity.

The invention relates to a device and method for detecting the wheel center depth of an aluminum wheel cast blank, the device includes a roller way tray, a position sensor, a frame, a CCD camera, a programmable controller and a laser distance measurement sensor, an upper servo-cylinder, a motor support, a servo-motor and a lower servo-cylinder. The invention has the following advantages: the method for automatically detecting and identifying the wheel center depth of an aluminum wheel cast blank is utilized for the identification and classification of wheel cast blanks, so as to reduce the influence of large casting dimension tolerance on the machining dimension tolerance, increase the acceptability rate of products from the automatic machining unit, ensure that the production line automatically runs with high quality and quantity and also reduce the labor intensity of operators.

A saddle-riding vehicle wheel drum is formed of a cast or molded article and includes: a drum body including a cylindrical body section and a flange section formed on the drum body at each of axially opposite ends of the drum body; and an annular collar fitted to an inner circumferential surface of the drum body at one of the axially opposite ends.

Provided discloses an integrated axle assembly and structural assembly. The integrated axle assembly comprises an axle tube assembly extending in a first direction; a front support arm extending circumferentially from the axle tube assembly in a second direction perpendicular to the first direction for attachment to the frame; a rear support arm extending circumferentially from the axle tube assembly in a third direction away from the second direction for mounting a resilient assembly; and a brake base plate extending in a peripheral direction from the circumference of the axle tube assembly; the axle tube assembly, front bracket arm, rear bracket arm and brake base plate are molded in one piece, which improves the assembly efficiency.

A process for manufacturing a light-alloy hybrid wheel implements the following separate operation phases: making a flange with an internal profile capable of constituting a tire bead seat; making a rim with, on one side, an outer profile capable of constituting a tire bead seat and, on the other side, a circular flank for assembly with a part of the flange; assembling the flange with the rim, at the seat of said flange and the circular flank of the rim. The rim is made according to the following consecutive operations: an operation of manufacturing a circular flank; then an operation of expanding said circular flank to the size of the final rim in a single step; then an operation of cold or hot flospinning of said circular flank so as to obtain the rim in the final shape and profile thereof, comprising a shoulder only on the side that will not be welded to the flange.

The present invention discloses a wheel mold spraying device, which is composed of a frame, a servo motor, a servo electric cylinder, a hollow shaft, a nozzle and the like. Four side molds of a wheel are respectively placed on four slide plates; hand wheels are rotated to adjust the slide plates to proper positions through lead screws and guide rails; the servo motor drives the rotation of the hollow shaft and the nozzle through belt wheels and a synchronous belt, and the nozzle is automatically opened; and through guide posts, the servo electric cylinder lifts the nozzle to the top end while rotating, in which case the process of spraying for the four side molds can be completed.

A portal axle as well as a method for manufacturing a portal axle for a rail vehicle, which has an axle centre part extending along a longitudinal axis and two kingpins one of which sits on a first end section of the axle centre part and a second on a second end section of the axle centre part formed opposite to the first end section. The kingpins are oriented away from the axle centre part and form an axis of rotation in use for a rail wheel rotatably mounted on the respective kingpin. The portal axle has optimised usage properties with minimised weight. This is achieved by a longitudinal opening extending in the longitudinal direction of the portal axle being formed in at least one of the mould components. The invention further provides a method for manufacturing an axle of this type.

An wheel hub made from cast material, in particular for commercial vehicles, comprising a wheel hub body, wherein the wheel hub body consists of the axially successive sections of an outer extension section, a neck section and preferably a brake disc section, further comprising a wheel flange, wherein the wheel flange is formed integrally on the wheel hub body, preferably in the region between the outer extension section and the neck section, and a through hole, wherein the through hole extends axially through the entire wheel hub body, wherein the outer extension section has an inner sleeve and a reinforcing skeleton, wherein the reinforcing skeleton and the inner sleeve are arranged coaxially, and the reinforcing skeleton surrounds the inner sleeve.
