Abstract: The disclosed invention is a novel method for constructing a Torsional Vibration Damper (TVD). The traditional means used to construct the hub of the TVD was to employ a single material. The disclosed invention essentially discretizes the construction of the TVD hub into three regions: nose, spokes, and flange, and simultaneously aligns unique materials and manufacturing methods for each region with the structural loads borne thereby. Consequently, the invention helps in reduces four unwanted characteristics: (1) mass; (2) polar mass moment of inertia; and (3) casting scrap; and (4) cost. Furthermore, because of this construction other enhancements to the axial and angular structural integrity of the TVD can be reaped in certain cases.

Abstract: A low-speed vehicle wheel assembly includes a rim, at least three spokes, connectors, a central bearing seat, and bearings. Outer ends of the spokes are fixedly connected to an inner side wall of the rim through the connectors, respectively. Inner ends of the spokes are fixedly connected to an outer wall of the central bearing seat. The bearings are fitted in bearing holes of the central bearing seat, respectively. Because the rim and the central bearing seat are independent components, each component can be made with an independent mold and assembled according to the diameter of the wheel. The cost of the mold is lower, and the components are more versatile.

Abstract: A vehicle wheel having a rim and a disk. A disk flange of the disk may have a non-contact portion non-contacting a radially inner surface of the rim, at a radially outer extension of a width center line of a spoke.

Abstract: A wheel bearing spindle is produced by an improved method which provides adequate structural clearance from the sharp edge of a wheel drum hub, while actually improving the effective yield strength of the spindle. The spindle is produced from a near net shape steel forging which has a cylindrical spindle and flat wheel flange radiating therefrom. The circular hub of a brake drum fits radially closely over the pilot, and abuts with the wheel flange. Therefore, the juncture of the pilot and flange needs to be relieved or cut away somehow, both radially and axially, in order to assure non interference with the circular edge of the hub, which could prevent the rest of the hub from intimately abutting the surface of the wheel flange. The radial component of the clearance is provided by conventionally machining a channel radially into the pilot. This can be done, since it does not weaken the flange.

A cylindrical support is secured to the wheel. Radially-inwardly facing arcuate brake lining structures are secured to the cylindrical support. Brake shoes are mounted upon a non-rotatable part of the automotive vehicle in spaced positions around the rotational axis of the wheel support. A pressurized-fluid operating system of a specifically-defined structure is provided for moving the brake shoes in a braking action radially-outwardly from inactive positions towards, and frictionally-engaging, the brake lining structures, and for returning the brake shoes radially-inwardly to the inactive positions upon termination of said braking action.

Abstract: An improved radial braking system uses the power of the cyclist's back pedaling to bring the braking member into contact with the rim of the wheel. The system allows for the direct contact of the braking member with the middle portion of the outer surface of the rim rather than to the side of the rim, as is common with the caliper type brakes. A rim having a laterally disposed lip for mounting of the spoke allows for an unobstructed middle portion for contact with the braking member.

Radially disposed outer ends of the spokes have plain terminations which are welded to form a plug anchor within circumferentially spaced bores in the felly to secure the spokes. The bores are preferably situated in inwardly extending dimples which are formed in the felly. The bores are partially frusto-conically shaped and are formed by a method using a circular punch and corresponding die.

The turned marginal edge portions serve as reinforcing ribs for the spoke plates to thereby increase the mechanical strength and rigidity of the spoke plates.

Abstract: An automotive vehicle wheel having a solid wheel body, provided with replaceable rows of inner and outer spokes.

Such replaceability is made possible by providing each spoke with a spring-loaded longitudinally moveable mounting member which places such spokes in longitudinal compression so as to hold them in place upon the wheel body.

Abstract: A spoked wheel and method for assembling the same in which formed sheet metal spokes are disposed between the rim and hub and are attached to each by portions on the spoke which are bent over and crimped on the side portions of the rim and the hub bushing. The ends of the rim are held together by one of the spokes, which is crimped over the junction of the rim ends, thus requiring no riveting or welding of the rim ends. A semi-pneumatic tire is mounted on the rim and assists in holding the crimped portions of the spoke in place on the rim. The wheel bearings are press fitted into the hub bushing and secure the crimped ends of the spokes in place on the hub. In the method of making the spoked wheel, the rim is bent into an annular shape and the rim ends are brought into close proximity. One spoke is secured to the rim at the junction point of the rim ends and holds the ends in that position.

Abstract: A vehicle wheel assembly and method and apparatus for making the assembly in which an outer tire rim and wheel center are fabricated into a secure one-piece unit. Secure attachment and restraint of the two components into one unit are accomplished through a dimpling process in which both components are nested together at a plurality of points through stamping. While very applicable to a steel rim or steel center wheel construction, the invention is adapted for use on several metallic wheel constructions to avoid pneumatic leakage associated with riveting or problems arising from welding of the two components. A fixture and hydraulically operated tool construction utilizes male and female tooling to accomplish the dimpling process in which regions of the wheel rim and center are deformed by force to nest together.
