Abstract:
A traveling toy wheel whose simple configuration allows multiple devices to be enjoyed and can further change fine offsets is provided. The traveling toy wheel includes a first rim member to which a tire is mounted and a second rim member which includes a fitting portion into which a wheel hub of a traveling toy is fitted. Fitting holes as fixing portions are provided in one of the first rim member or the second rim member and elastic convex pieces as fixed portions are provided in the other of the first and second rim members. When the elastic convex pieces are fitted in the fitting holes, the first rim member and the second rim member are jointed relatively unmovably. A plurality of fitting holes are arranged at different positions, so that it is possible to easily adjust an offset of the wheel.
Abstract:
A central tire inflation system for maintaining tire inflation on a vehicle is provided. The central tire inflation system includes a rotary union assembly having a housing that is coupled to and rotates with the hubcap. The housing is rotationally coupled to a stationary shaft. A flexible torque transfer shaft is connected to the stationary shaft on one end and to an axle plug on the other end. The axle plug has a hub forming, a bore where the hub is movable on a web of material. The flexible torque transfer shaft and hub have cooperative non-circular shapes to resist rotation. An air vent is provided in the rotary union assembly that is isolated from the lubrication area, which inhibits the pressurized air from the central tire inflation system from pressurizing the lubrication area.
Abstract:
The present invention provides a tractor which is configured such that front wheel axles are disposed above upper portions of front wheels so that the front wheels are prevented from being impeded by the front wheel axles even when the front wheels are steered to maximum angles in a clockwise or counterclockwise direction and turned to an angle over or approximate to a right angle with respect to the longitudinal direction of the tractor, whereby the tractor can be turned in place by manipulating a steering wheel.
Abstract:
A multi-purpose combined ladder/cart assembly capable of being converted into a plurality of ladder and cart configurations, including an extension ladder, a step ladder, a load-carrying cart, a pull cart, and a hand truck. The multi-purpose combined ladder/cart assembly includes a plurality of frame members that are pivotal with respect to each other and capable of being retained in variety of desired positions in order to easily configure the assembly in any of its various configurations. The travel characteristics and center of gravity of the cart configurations of the assembly are variably selectable, depending upon the load to be carried, by simply selecting various combinations of differently sized wheels to attach to the assembly.
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:
An assembly for supporting axles of different diameters in a wheel, in which the wheel has a hub with a bushing receiving portion having an interior surface of a first diameter. The bushing has a portion with an outer surface of a second diameter, somewhat smaller than the hub first diameter, to fit axially into the hub receiving portion and an axle receiving portion having an inner surface of a third diameter that accepts an axle of a corresponding diameter. The hub bushing receiving portion has a first seating on its interior surface and the bushing outer surface has a second seating. A fixing element in the bushing second seating expands radially of the bushing into the hub first seating when the bushing is inserted axially into the hub bushing receiving portion and locks the bushing to the hub.
Abstract:
A wheel assembly for a storage and retrieval machine which is travelable on a rail along a path adjacent overhead storage locations which store objects delivered to and retrieved from the locations by the storage and retrieval machine. The storage and retrieval machine includes a base which is supported on the rail by the wheel assembly. The wheel assembly comprises a wheel engaging the rail and having a horizontal axis of rotation and an upwardly extending axis projecting through the wheel. A wheel support is affixed to the base and includes a bracket on which the wheel is mounted. The bracket has a plate member extending laterally of and around the upwardly extending axis of the wheel. A positioning mechanism is provided for angularly positioning the wheel about the upwardly extending axis and has a plurality of set screws spaced from and in a surrounding relationship to the upwardly extending axis and engaging the plate member of the bracket upon which the wheel is mounted. The wheel support also includes a frame affixed to and vertically movable on the base for positioning the height of the wheel and thereby the height of the base.
Abstract:
An apparatus is set forth to vary the wheel base configuration of a tractor-trailer apparatus, wherein the trailer is positionable upon a carriage mounted upon "C" shaped channel guide rails mounted on the framework of a tractor organization. The rails include a reciprocating carriage mounted thereon for engagingly latching and reciprocatingly positioning and securing the trailer relative to the tractor framework, whereupon retraction of the carriage simultaneously secures the trailer to the tractor and elevates the rear tractor wheels out of contact with an associated roadway. An electrical interlock is provided for indicating proper orientation of the trailer relative to the tractor.
Abstract:
A vehicle attachment has a pivoting frame connected to the rear driven axle of a vehicle, drivable wheels mounted on opposite ends of a drivable axle, an adjustable tension element that is capable of providing varying degrees of downward force on the drivable wheels. A sprocket is connected to the vehicle rear axle and another sprocket is connected to the drivable axle, the two sprockets being interconnected by a chain such that rotation of the vehicle rear axle causes rotation of equal velocity of the drivable axle.
