A preform for fabricating a wheel rim and a method of making a preform is provided. The preform includes a main section and at least one secondary section, each section being formed from composite materials, such as triaxially braided composite material that includes fibers oriented in at least three directions. The main section forms at least part of a lateral section of the preform and the secondary section forms at least part of a radial portion of the preform, the radial portion of the preform being generally perpendicular to the lateral section of the preform. The preform is fabricated from a plurality of composite layers, at least some being custom composite layers having a plurality of axial fibers interwoven intermittently with substantially consistent first and second sets of biased fibers. In some embodiments, the preform is initially fabricated in an intermediate configuration prior to being moved to a final configuration.

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.

A wheel assembly includes a hub for attachment to a rotatable axle, a plurality of first friction plates each engaging a first surface of one part of a plurality of parts of a tire assembly, a plurality of second friction plates each engaging a second surface of the one part of a plurality of parts of a tire assembly, the second surface being radially opposite the first surface, and a plurality of radial cable members each connecting the hub to the tire assembly such that each radial cable member extends radially away from the hub, bends circumferentially adjacent a corresponding second friction plate, bends radially outward and back circumferentially adjacent a corresponding first friction plate, and radially inward to a first point of intersection with the same radial cable member.

The present invention provides a disc wheel with variable thickness for agricultural tractor application. According to an embodiment, a disc wheel with variable thickness includes an axle mounting area 201, an axle mounting radius area 202, a wheel weight mounting area 203 and a connection bracket mounting area 204, wherein said disc wheel includes maximum thickness at the axle mounting area 101 and at the connection bracket mounting area 204. The disc wheel 200 uses less material input for imparting high strength. Further, the disc wheel 200 with variable thickness prevents bolt hole failures by providing higher strength at a centre. The thickness from the axle mounting area 201 gradually decreases up to the end of the wheel mounting area 203 and matches the thickness at the connection bracket mounting area 204. The disc wheel 200 with variable thickness is achieved using flow forming process 402.

A tubular type torsion beam is manufactured by bending and welding and coupling a plate material. The plate material has a plurality of protrusions disposed on a plurality of side surfaces in a width direction of the vehicle. The torsion beam is manufactured by molding the plate material in a pipe shape by bending the plate material in the width direction and molding the plate material to dispose the plurality of protrusions to contact each other to form a gap between the plurality of side surfaces of the plate material and then welding and coupling the plurality of side surfaces of the plate material.

In order to provide solutions for soiling problems and corrosion problems in the area between a pole ring (41) and the hub interior, arranged behind it, of a wheel hub assembly having a wheel hub (1) which ends inside the vehicle in a hub section (50) whose internal circumference (15) defines an opening (55) for the central passage of the stub axle (6) and on which a fastening device (42) of a pole ring (41) of an ABS sensor is mounted, wherein a pulse generator section (43) which is embodied in one piece with the fastening section (42) is a component of the pole ring (41), which pulse generator section (43) extends from the fastening section (42) to the wheel hub axis (A) and is provided with openings (44, 44L) distributed uniformly in the circumferential direction; in a first embodiment the pole ring (41) extends with its pulse generator section (43) towards the wheel hub axis (A) to such an extent that the opening (55) between the wheel hub (1) and stub axle (6) is for the most part covered towards the interior of the hub.
