Abstract:
The invention relates to a method for rotationally driving an aircraft wheel, the wheel being equipped with a rim comprising two half-rims assembled by bolts (5), in which method a drive member for generating a torque for driving the wheel is controlled, characterized in that the method comprises the transfer of the drive torque to the wheel via the rim assembly bolts.
Abstract:
The present invention is a system and method for transporting a container including a which is assembled into a box; at least one axle affixed by a user and associated with said box; at least two wheels dependent on said axle; a strap constructed and arranged for securing about the perimeter of said box and configured for movement, yet allowing stackability, and side by side placement of box for mass transportation.
Abstract:
A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.
Abstract:
A wheel retaining device is provided for axially retaining a wheel on an axle having a notch. The cap is adapted for being affixed to a wheel. One or more springs is affixed to the cap at a lateral edge. The springs have a first position wherein the distal ends are located radially outward from the lateral edge. The springs are bendable into a second position wherein the springs are adjacent to the inboard side of the outer plate so that distal ends are urged inward. The distal ends include a protrusion that is adapted for being received in a notch on the axle. The cap is held onto the wheel by tabs that extending into apertures and catching behind the apertures. The cap is designed for maintaining the lateral position of the axle with respect to the wheel to which it is attached.
Abstract:
A locking hub that is useful for wheels on small vehicles. Such wheels may use a press fit or integrally cast version of the invention. The locking hub fits over a shaft. The hub has a bore for receiving the end of the shaft. An outer member is connected to and spaced from the hub. A finger is adjacent to the bore and has a protrusion that extends into the bore. The finger is resilient and movable between a first and second position. The first position has the protrusion protruding into the bore and the second position has the protrusion outside of the bore with the finger being bent radially outward. The shaft has a notch or hole that receives the finger. A locking device may selectively be placed between the outer member and the hub to prevent the finger from moving into its second position, thereby locking the hub onto the shaft.
Abstract:
A wheel assembly including a wheel that has a hub and an annular rim. The hub is disposed at or near the center of the rim. The wheel assembly also includes an axle sleeve which is coaxial with the hub. A method of constructing a wheel is also provided. A wheel having a bore is blow molded. The wheel is extracted from a mold. An axle sleeve is fitted the bore in the wheel.
Abstract:
A wheel of a golf cart includes a connecting member, a rotary main body, and an axle for the rotary main body; the connecting member can be detached from a support part of a main frame of the golf cart for reducing dimension of the cart in packaging and transportation; the connecting member has an engaging element pivoted thereto and biased to an engaging position by means of a torsion spring; the axle can be easily separated from the rotary main body for maintenance and replacement; the axle has an annular engaging recess thereon, and can be inserted in the connecting member to engage the engaging element for connecting the rotary main body to the connecting member; thus, the rotary main body can be easily separated from the main frame of the golf cart together with the axle after the engaging element is pivoted such as to disengage the axle.
Abstract:
A railroad car wheelset has an axle with one wheel rigidly attached as in conventional railroad practice. This wheel is permitted to rotate by journal bearings either on the extreme ends of the axle or inboard of each wheel location. At the location of the other wheel, the axle is provided with a smooth surface and a self-lubricating bearing is provided as a part of a hub on the axle. The axle shaft is provided with a boss for preventing the independently rotating wheel from migrating laterally out of proper alignment. A self-lubricating thrust bearing is located between this boss and the side of the wheel to eliminate any possible galling between the two moving surfaces. A removable retainer plate is located on the other side of the independently rotating wheel to prevent the wheel from moving laterally in that direction. Adjacent the removable retainer plate is an electrical contactor which can conduct an electrical current from the wheel to the axle shaft, to permit the wheelset to properly operate railway signals or other systems dependent on electrical continuity. In lieu of the self-lubricated bearings, the bearings can be comprised of a lubricant coating permanently bonded to the bearing surface of the hub adjacent the independently rotatable wheel.
Abstract:
A wheel assembly which includes a wheel having a central bore and an attached hubcap. An axle is fitted into the central bore of the wheel assembly and interlocks with the hubcap, serving to secure the wheel assembly to the axle while permitting movement of the wheel relative to the axle.
Abstract:
An all terrain baby stroller using an axle assembly that allows the rear wheels to be easily and quickly mounted and removed from the stroller frame without tools. The axle assembly has each rear wheel rotatably mounted on an outward end portion of a stub axle. A tubular rear axle defines a cylindrical interior chamber with an outward end opening sized to slidably receive the stub axle inward end portion therethrough for positioning of the stub axle inward portion coaxially within the interior chamber. When so positioned, a circumferential groove of the stub axle inward end portion is positioned within the interior chamber. The tubular sidewall of the rear axle has an aperture positioned axially inward from the interior chamber outward opening and at a location to coincide with the circumferential groove. A lock pin is carried by a strip spring and is movably disposed in the sidewall aperture for selective movement between an engagement position and a disengagement position. In the engagement position the pin extends into the interior chamber and into the circumferential groove of the stub axle inward end portion to prevent axial withdrawal of the stub axle from the interior chamber. When in the disengagement position, the pin is sufficiently clear of the circumferential groove to permit the stub axle inward end portion to be axially inserted into and removed from the interior chamber.
