Abstract:
A high temperature-resistant wheel, comprising: an elastic hub assembly (1), which has a thermal insulation layer integrated therewith so as to insulate the elastic hub assembly (1) from exterior high temperatures; and a rigid wheel barbed ring (2), which has the elastic hub assembly (1) fastened inside and rotates together with the elastic hub assembly (1). A robot, which comprises the high temperature-resistant wheel.
Abstract:
A non-pneumatic wheel having a thermoplastic wheel hub includes a center hub for attachment to a wheel bearing of a vehicle. The center hub has a central shaft aperture extending axially therethough and a plurality of lug apertures spaced radially from and circumferentially about the central shaft aperture. The thermoplastic wheel hub also includes a plurality of ribs extending radially outwardly from the center hub. The thermoplastic wheel hub further includes a cylindrical tire mount connected to the ribs and extending axially in substantially a cylinder for mounting a non-pneumatic tire thereon.
Abstract:
An omni-directional wheel for an omni-directional vehicle that exhibits constant ride height, low vibration, and reduced maximum ground contact pressure is disclosed. The invention consists of a wheel assembly rotatably connected to the omni-directional vehicle chassis. The wheel assembly includes a hub on which free spinning rollers are rotatably mounted at an angle to the wheel axis. Constant ride height and low vibration operation are accomplished by configuring the rollers with an exterior profile, thickness, material properties and surface grooving to achieve constant deflection of the roller contact surface at all wheel rotation angles.

Abstract:
A chin ring heat shield for a wheel assembly arranged to provide a shield between convection and radiation heat from braking components and a tire of the wheel assembly, the chin ring comprising a first, radially extending, flat portion extending from a first chin ring end and a second, concave portion extending generally axially away from the first portion to a second chin ring end, wherein the axial length from the first chin ring end to the second chin ring end is sufficient to block a line of sight between the braking components and the tire when the chin ring is mounted between the braking components and the tire.
Abstract:
A method of manufacturing an aluminum wheel for a vehicle includes preparing a low density material having particles pulverized. A binder is supplied to the low density material so that the low density material is mixed in a paste state. A wheel core manufacturing mold is heated to 200 to 350° C. and injected into the wheel core manufacturing mold. The wheel core manufacturing mold is closed, a pressure of about 5 to 20 bar is applied, the pressure is maintained for 1 to 5 minutes to solidify the low density material, and the wheel core is ejected. The ejected wheel core is mounted on an aluminum wheel casting mold. The aluminum wheel casting mold is closed, and a pressure of about 1 to 2 bar is applied, and an aluminum molten metal is injected. The aluminum wheel is then ejected from the aluminum wheel casting mold.
Abstract:
A differential wheel mounting for replacing a standard railroad axle assembly having a wheel seat portion which includes a sleeve, a railroad wheel with a running surface for contacting a rail and a rolling bearing assembly detachably mounted to the sleeve and railroad wheel. The sleeve may include a shoulder and removable keeper for retaining the rolling bearing assembly. The wheel may also include a shoulder and removable keeper for retaining the rolling bearing assembly. The rolling bearing assembly sustains both radial and thrust loads during normal operation of a railroad car. The wheel may also include a removable tire section.
Abstract:

In alternative embodiments, omni-direction wheel modules for imparting omni-directional locomotional capabilities to vehicles and objects. In further alternative embodiments, apparatus and methods for transporting and loading and off-loading munitions utilizing specialized, omni-directional capable vehicles for improved efficiency and/or safety.
Abstract:
A hubless wheel for a vehicle which provides advantageous weight and aerodynamic properties. The wheel includes a rotationally stationary inner hoop, coupled to the vehicle, and a rotatable outer hoop, concentric with the inner hoop. The inner hoop and outer hoop are both fabricated with a woven fiber composite shell. A ground engaging tread is disposed on the radial periphery of the outer hoop. Bearings, preferably three rotating bearings spaced circumferentially around the inner hoop at approximately 120.degree. intervals, are mounted on the inner hoop to be rotationally stationary therewith and each include a support surface on their respective radial peripheries. The support surface is particularly contoured to operatively engage a bearing engaging surface located on the inner periphery of the outer hoop. The outer hoop is axially and radially supported relative to the inner hoop through this engagement to allow rotation therebetween.
Abstract:
The invention is directed to a heat shield structure (8) for a wheel (1) which comprises a base structure (11) that is at least partially made from a composite material. The heat shield structure (8) is arranged on the base structure (11) and is at least partially covering the base structure (11).
