摘要:
A vehicle wheel includes a wheel hub rotatably mounted on a stationary axle and a running tread, tire or the like connected with the wheel hub. A device for connecting structural components such as, for instance, a transmission part or a brake disk, for the purpose of transmitting a torque between the wheel hub and the structural component to be connected is provided on the external end face of the wheel hub. In order to provide a modularly designed vehicle wheel easy to mount and dismount, the device for connecting structural components is applicable facultatively and a fastening device spacially separated from the device for facultatively connecting structural components is provided on the external end face of the wheel hub. The vehicle wheel may be designed as a driven wheel or a loose wheel with or without brake. By separating torque transmission and power transmission, mounting and dismounting of the vehicle wheel is substantially facilitated.

The invention relates to a rubber-sprung rail wheel having a wheel tire (1), which has a peripherally-extending web (3) on the inner side (2) thereof, and a wheel rim (4) provided with two legs (6, 7) on the outer side (5) thereof, and two rubber rings (8, 9) that are arranged between the wheel tire (1) and the wheel rim (4). The rubber rings (8, 9) are arranged on both sides of the web (3) and are laterally delimited by the legs (6, 7). A first gap (12) is formed between the inner side (2) of the wheel tire (1) and the end edges (10, 11) of the legs (6, 7) and the rubber rings (8, 9) and a second gap (12) is formed between the outer side (5) of the wheel rim (4) and the end edges (13, 14) of the web (3) and the rubber rings (8, 9). The web (3) and the legs (6, 7) are configured in such a way that the rubber rings (8, 9) are inclined with respect to the central plane of the web (3). According to the invention, the rubber rings respectively have a conically expanded region on the inner diameter (14) and outer diameter (11), and a region having a constant wall thickness between the expanded regions.

A wheel for rail vehicles with at least one disc which is connected to an axle, and with a wheel rim having a tread or surface surrounding the disc, while the rail tread in engagement with the rim tread results in contacting points of the wheel during straight forward drive of the vehicle located on the tread or track of the rails. At least within that region of the rim which contains the above mentioned rail contacting points of the wheel rim the wheel rim is turnably connected to the disc for turning about an imaginary axis located in about the driving direction of the wheel.

摘要:
A wheel assembly for a wheeled vehicle utilizes interchangeable wheel hubs to secure various types of tires to provide better performance and maintenance on the vehicles. The design of the hubs is such that fabrication costs are reduced as well as costs for maintaining wheel inventories. The hubs are designed with locking elements and shoulders to ensure that tires are effectively secured in the wheel assembly. The hub is configured so that replacement of worn tires is done quickly, without having to touch the wheel bearings or drain the lubricant.
摘要:
A wheel comprises a main body, a tread making a contact with a top face of the rail head of a rail, and a flange. At least at a portion of the wheel tread which is in contact with the rail, there is provided a tread-forming component formed of a ceramic-particle-dispersion reinforced aluminum composite material, which has ceramic particles mixed in an aluminum alloy. The tread-forming component is formed in a ring shape, fitted into a tread-forming component receiving portion and fixed to the main body by a fixing member.

A rubber-sprung wheel for rail vehicles includes a wheel tire which is connected to a wheel rim by a rubber insert that is formed by two flat rings that are arranged so as to be essentially vertical in relation to a wheel axle. The two flat rings are held, under considerable axial prestress, between an inner circumferential middle web of the wheel tire and two outer flanges of the wheel rim. At least one of the flanges is seated on the wheel rim with an interference fit that is designed as a conical press fit, such that a cone of the flange in a stress-free state has a lesser conicity than does a cone of the wheel rim, and in a pressed-on state rests on an entire surface against the cone of the wheel rim, at an even surface pressure across an entire width of the interference fit.

In order to reduce torsional vibrations and wheel slip in a wheel set for a rail vehicle the wheel set comprising a pair of wheels connected by an axle is provided with a vibration absorbing device comprising a mass, resiliently mounted on the wheel set and adapted to oscillate at the resonant frequency of torsional vibrations of the wheel/axle system. A method of preventing or reducing torsional vibrations in a wheel set of a rail vehicle is also disclosed, the method comprising determining the resonant frequency of torsional vibrations of the wheel/axle system and resiliently mounting a vibration absorbing device in the form of a mass, on the wheel set, the mass and its resilient mounting being selected to oscillate at or near that resonant frequency.
摘要:
A differential wheel mounting for replacing a standard railroad axle assembly having a wheel seat portion which includes a sleeve having several sliding surfaces fixedly mounted over the wheel seat portion of the axle, a railroad wheel with a running surface for contacting a rail and a plain bearing member detachably mounted to the railroad wheel. The plain bearing member has non-metallic bearing surfaces that mate with the sliding surfaces on the sleeve so that the bearing member and the attached wheel are laterally confined on the sleeve while being rotatable about the sleeve. The plain bearing member sustains both radial and thrust loads during normal operation of a railroad car.
