Abstract:
Embodiments of collapsible wheels and methods of making collapsible wheels are generally described herein. Other embodiments may be described and claimed.
Abstract:
The invention relates to an equipment for a bicycle wheel. The equipment comprises at least one profiled wing-shaped projection adapted to be secured to the inner surface of the rim of the wheel.
Abstract:
A method for making a carbon fiber wheel rim includes: preparing an outer supporting piece; winding a carbon-fiber yarn around the outer supporting piece to form carbon fiber layers and to constitute an engaging seat preform; connecting an inner supporting piece to the engaging seat preform; connecting a reinforcement piece to the inner supporting piece; winding a carbon-fiber yarn around an assembly of the engaging seat preform, the inner supporting piece and the reinforcement piece to form carbon fiber layers; fixing the assembly with the carbon fiber layers to form an outer frame preform; and cutting the outer frame preform and the engaging seat preform to form a trench and removing the outer supporting piece therefrom.
Abstract:
The invention relates to an aircraft wheel comprising a rim and a tyre (20) received on the rim, the rim comprising two parts (1; 2) assembled with one another by means of assembly bolts (5), one of the parts comprising a recess (3) in which is arranged a seal (4) which is interposed between the two parts, the wheel being characterized in that at least one of the parts comprises at least one duct (6) extending beneath the seal so as to establish a leakage path between on one hand a volume of gas delimited by the rim and the tyre, and on the other hand a space between the parts, the path being nominally closed by the seal when the bolts are tightened correctly but allowing gas to leak from said volume when the bolt associated with said opening is not tightened correctly or is absent.
Abstract:
A bicycle rim is basically provided with an outer rim portion and an inner rim portion. The outer rim portion has a ring shape of a first material. The inner rim portion is joined to the outer rim portion. The inner rim portion has a ring shape of a second material with an internal residual stress distribution resulting from the ring shape being formed by spinning of the second material.
Abstract:
A vehicle wheel, including a peripheral rim with a radially outboard spoke bed and an apex region radially inboard from the spoke bed portion; a central hub with a hub flange; a plurality of spokes extending between the rim and hub, with a first portion connected to the spoke bed and a second portion connected to the hub flange. The apex region includes a first apex portion and a second apex portion axially adjacent the first apex portion and a circumferential seam between the first apex portion and the second apex portion.
Abstract:
A composite rim including a reinforcing assembly is provided. The composite rim includes a first sidewall portion, a second sidewall portion, a radially outer portion and a reinforcing assembly. The radially outer portion includes a radially outwardly-facing tire-engaging surface. The reinforcing assembly is disposed proximate the tire-engaging surface and includes a reinforcer and a containment member for containing the reinforcer. The reinforcer has an axis extending circumferentially about the composite rim and is configured to reinforce the composite rim in a direction generally perpendicular to the axis of the reinforcer.
Abstract:
A robotic vehicle capable of collapsing into a small form factor for ease of transportation and providing for a quick transition to a deployed configuration. The vehicle can be configured to carry a payload when deployed. The vehicle can have an elongate body with two folding spoke-wheels at either end of the body that conform to the shape of the body when collapsed and extend perpendicular to the body when deployed. The vehicle can have an elongate body with two folding arms that each includes a drive motor and a gear assembly. The gear assembly is configured to receive removable wheels at either end of the body. The arms can be parallel to the length of the body when collapsed and extend perpendicular to the body when deployed. The vehicle can include a removable bracket configured to receive an explosive payload.
Abstract:
A rim and a method of producing a rim for bicycles and the like includes a rim body and a rim base provided thereon and lateral rim flanks provided with rim flanges. The rim flanges include a fibrous composite material having at least one fiber layer. The rim flanges include inwardly overhanging bulges of squashed fiber layers between which a tire can be accommodated at the rim body.
Abstract:
A composite rim (1) for a bicycle wheel (60). The rim has at least one braking surface (20) and a wear indicator (40) that indicates when a predetermined level of wear has been reached at the braking surface (20). The wear indicator (40) is arranged in the rim (1) so that its does not affect the outer surface of the rim (1) or weaken its mechanical strength.
