Abstract:
A dual wheelend for an axle assembly having a rotatable axle shaft. The wheelend comprises a spindle defining a first axis. An intermediate hub is supported on the spindle for rotation about the first axis during rotation of the axle shaft. An inner wheel hub and an outer wheel hub are adjacent one another and are each supported on the intermediate hub for rotation about the first axis. A differential mechanism interconnects the inner and outer wheel hubs. A pin is disposed through a pinion along a second axis and couples the differential mechanism to the intermediate hub for driving the wheel hubs during rotation of the intermediate hub and permitting relative rotation between the wheel hubs relative to the intermediate hub. The pin includes proximal end with a head disposed on the proximal end for engaging the pinion and sandwiching the pinion between the head and the intermediate hub.
Abstract:
A wheel assembly and a wheel are suitable for use with a mobile platform. The wheel assembly comprising a first wheel and a second wheel, each wheel comprising a hub having a central axis of rotation, and at least two wheel lobes coupled to the hub, the wheel lobes extending radially from the hub and spaced around the central axis of the hub, where the first wheel is rotatably mounted to the second wheel on a common axis, and a control mechanism rotates the first wheel with respect to the second wheel.
Abstract:
The invention is a hybrid wheel apparatus with a hybrid roadway apparatus that greatly reduces the energy lost due to rolling resistance where operation is on the hybrid roadway, but the system is configured to allow operation on conventional roads as needed.The hybrid wheel system is a steel wheel used in combination with a rubber tired wheel. The hybrid roadway is a low profile steel rail fixed to the otherwise conventional road surface, which is preferably concrete but could also be the very common asphalt composition.Where roadways are appropriately equipped with rails, the rail top surface is elevated over the roadway surface, and dimensions are set so that most of load force is carried on the steel wheel for general forward travel. Where the rail is absent the load is carried on the rubber tire, and the steel wheel is elevated above the roadway surface such that contact between the steel wheel and the roadway is prevented.
Abstract:
This invention is directed to a novel amphibious surface vehicle (10) having a hull like chassis (11) with a plurality of rotary engagement devices (14) adapted for travel over various surface terrains and fluidic substances (17). Each engagement device includes rotors (16) having a multi-lobular periphery that provides improved tractive and propulsive attributes. The rotors are coupled through a driven eccentric hub (30) and phased by a non-circular internal gear pair (27, 37) so as to provide synchronized linear motion upon a weight bearing surface (15). The rotors with an overlapping contact ratio which produces increased traction and bearing area translating to improved overall performance upon a planar surfaces (15). This overlapping action becomes more paddle like when surface penetration occurs or by adjusting lever (19) aggressively changing the phasing incidence of the rotors (16), which is conducive to fluidic propulsion on water or other low shear strength substances (17).
Abstract:
A truck wheel central cover includes a main body provided with plural projecting holders spaced apart equidistantly and respectively formed inside with a recessed chamber disposed with an annular base at its lower side. Each annular base is cut with plural notches, and has its interior fixed with plural resisting members and its inner side formed with an engage edge. Plural coupling members are respectively received in the annular bases of the main body, respectively having a hexagonal accommodating chamber with an insert hole communicating with the outside and having projecting members respectively fixed at its inner end corners. Each coupling member is cut with plural notches, having its outer wall bored with an annular engage groove. By mutual engagement, the central cover can conveniently and quickly be assembled on a truck wheel rim.
Abstract:
This invention relates generally to vehicular transportation for humans and freight by roadway and railway. More specifically, this invention relates to a unique combination of a novel roadway wheel and pneumatic tire assembly, incorporating a known automatic inflate-deflate system and a novel lightweight railway wheel; both wheels then coupled and concentrically assembled on a common axle with special provisions for the known automatic inflation and deflation of the pneumatic roadway tire.
Abstract:
For fastening an auxiliary wheel to the wheel of a vehicle, bolts are fixed to the auxiliary wheel, which bolts are aligned substantially parallel to the wheel axle of the auxiliary wheel. Each of the bolts has a head-shaped swelling which can be inserted into slot-shaped recesses provided on the wheel of the vehicle and can be pushed into the slot-shaped recesses. The head-shaped swelling of the bolts is hereby held in the slot-shaped recesses. The auxiliary wheel is locked in this position through locking means. A simple mounting and dismounting of an auxiliary wheel to the wheel of a vehicle is thereby obtained.
Abstract:
A wheel-and-tire apparatus having at least two coaxially mounted tires is disclosed in which the diameters of one or more of the tires in the apparatus may be adjusted to select the tire or tires which are to be in contact with the road surface. The apparatus facilitates the selective use of tires having different performance characteristics, as may be desired or preferred to suit particular road conditions or vehicle operating conditions. The diameters of particular tires are increased or decreased as required to achieve a desired configuration of relative tire diameters, using tire diameter adjustment means such as one or more pneumatic pumps mounted in association with the apparatus. Sensors monitor selected operational parameters of the vehicle and transmit corresponding signals to a computer which selects an optimal tire configuration to suit the particular combination of operational parameters received from the sensors. The computer then transmits a corresponding signal instructing the tire diameter adjustment means to adjust the diameter of one or more tires in the apparatus as required to achieve the selected optimal tire configuration.

Abstract:
A wheel covering apparatus for a heavy-duty vehicle is provided. The wheel covering apparatus includes a bracket that attaches to a wheel of the vehicle. The bracket has extending therefrom a guiding rod and a guiding barrel. The apparatus further includes a wheel cover and a wheel axle cover coupled thereto. The wheel cover is formed with an engagement hole and a guiding hole disposed in open communication with one another, such that the guiding hole may receive and transversely guide the guiding rod into engagement with the engagement hole. The wheel cover and wheel axle cover are secured to the bracket by a bolt passing therethrough to engage a threaded hole formed in the bracket.
