The present disclosure provides a method of manufacturing a one-piece wheel having a hollow structure for noise reduction. At least one embodiment of the present disclosure provides a method of manufacturing a one-piece wheel having a hollow structure for noise reduction, the method comprising: fabricating, by using one or both of gravity casting and low-pressure casting, an integral casting in which a disk portion and a wheel rim portion are integrally formed, wherein the rim portion includes an annular protrusion radially protruding from an outer circumferential surface; forming at least one cavity by bending the annular protrusion through flow forming to provide a bending portion, resulting in the cavity using the bending portion and one side of the disk portion; and performing a friction stir welding between the one side of the disk portion and one end of the bending portion.

The invention relates to a method for producing a bent torsional profile comprising the following process steps: a) provision of a plate made of planar sheet metal, b) reshaping of the plate through the introduction of a bent trough oriented in the longitudinal direction of the plate in a central length portion (6) of the plate at a distance from the front edges of the plate, forming legs between the trough and the longitudinal edges of the plate, c) reshaping of the legs in such a manner that an open profile is created, d) reshaping of the legs in such a manner that a hollow profile is produced, wherein a longitudinal gap is formed between the two legs over the entire longitudinal extent thereof and wherein an air gap is created between the legs and the trough in the region of the trough, e) joining of the two legs over the entire longitudinal gap.

(Task) To provide a wheel of an omni-wheel type which can be made at low cost, and a method for making such a wheel.

(Means to Accomplish the Task) The wheel (3) comprises a core member (32) consisting of a tubular member (140) formed with a plurality of V-shaped notches (142) on one side thereof, and bent into an annular shape so as to close the notches, and a plurality of free rollers (60) each rotatably fitted on a linear section (120) of the tubular member located between a mutually adjoining pair of the V-shaped notches via a bearing (122) provided with an inner race (124) and an outer race (126), wherein a raised piece (130) is provided for each inner race on another side of the tubular member opposite from the one side as well as a protrusion (138) so as to engage an end surface of the inner race and fixedly secure the inner race to the core member.

A vehicle axle body is provided for incorporation into a vehicle axle. The vehicle axle body may be comprised of first and second axle body pieces. The first axle body piece may define at least a portion of a lower surface of the vehicle axle body and at least a portion of one of a front surface and a rear surface of the vehicle axle body. The second axle body piece is secured to the first axle body piece and may define at least a portion of an upper surface of the vehicle axle body and at least a portion of the other one of the front surface and the rear surface of the vehicle axle body. The thickness of the first and second axle body pieces may be different. Suspension component supports may be integrally formed with the upper and/or bottom surfaces of the axle body.

Disclosed herein is a wheel, in particular for vehicles, such as motor vehicles, with a rim ring having an opening defined there through, and with a main support at least partially arranged in the opening in the rim ring. The wheel, despite having a low weight, provides adequate rigidity and strength and can be produced in a simple manner, while maintaining design flexibility. The main support of the wheel has a plurality of spokes, and a plurality of covering parts for at least partially covering the spokes, wherein the main support and the covering parts support the rim ring.

A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange;

and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

A manufacturing method for a wheel disc, includes forming a flange portion, wherein the flange portion is formed such that an inner mold and an outer mold having a cylindrical inner surface with a first inside radius larger than the first outside radius and placed above the inner mold coaxially to the inner mold are brought close relative to each other in an axial direction by one stroke so that the outer edge of the disc material is bent downward, and the cylindrical inner surface of the outer mold is provided with recessed portions hollowed outwardly in a wheel radial direction, the recessed portions being formed in ranges corresponding to the window portions in the wheel circumferential direction and in a range from a middle position to a bottom end in the wheel axial direction.

Systems and apparatuses include a tag axle system including an axle assembly, a linkage coupling the axle assembly to a vehicle chassis, and a hydraulic cylinder coupled between the vehicle chassis and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position, and acts as a spring damper suspension component.

The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

A commercial vehicle wheel including a rim configured to hold a tire and a wheel disc attached to the rim with an attachment region for removable attachment to a wheel carrier. The wheel disc is formed from at least two parts, which are joined together. At least one of the parts consists of a multiphase steel alloy or a heat-treatable steel alloy.
