A surface conditioning device for railway track rails and/or railway vehicle wheels includes a DC power supply, a supply of gas, a plasma delivery head connected to receive DC power from the power supply and gas from the gas supply, and an igniter for igniting the gas in the plasma delivery head. In use, plasma is generated within the delivery head by ignition of the gas in the delivery head. Plasma with gas is blown from the delivery head onto a railway track rail and/or railway vehicle wheel, thereby conditioning the rail and/or wheel.

A system for reprofiling a wheel set of a railway vehicle allows the center of rotation of the wheel set to move relative to supporting rollers. A cutting tool used to reprofile the wheel profile on a wheel set is moved relative to the center of rotation of the wheel set to maintain a constant distance between the center of rotation and the cutter. The rollers are maintained in a fixed position during the cutting process. The system avoids mechanically forcing a constant location of the wheel set relative to the center of rotation.

A two-piece rail wheel assembly is disclosed herein that allows a tire to be replaced without requiring disassembly of the rail vehicle or removal of components directly attached to the axle. In various embodiments, the rail wheel assembly comprises a center wheel hub attached to an axle of a railway vehicle and a tire configured to engage the rail. The center wheel hub and the tire may be bolted together via a stepped (or recessed) interface. When used with in-board bearing configurations, this rail wheel assembly does not require using a press machine, detaching the truck assembly from the rail car, or detaching the wheelset from the truck. When used with out-board bearing configurations, this rail wheel assembly eliminates the need to use a press machine or remove any other components of the wheelset from the axle.

A soundproof wheel includes a soundproofing device which is mounted to an inner peripheral surface of a rim section of the wheel. The soundproofing device is provided with: a fixing ring which is fitted in and fixed to a groove formed in the inner peripheral surface of the rim section; an elastic body section which is adhered to an outer peripheral surface of the fixing ring, is disposed within the groove, and has a plurality of elastic body pieces; and an additional mass section which is adhered to an opposite side of the elastic body section with respect to the fixing ring, is disposed within the groove, and has a plurality of additional mass pieces. The soundproofing device includes a plurality of dynamic vibration absorbers, each having an elastic body piece and an additional mass piece. This soundproof wheel allows for reduction in wheel vibration noise and is highly durable.

A maintenance assembly for a wheel assembly of an amusement ride vehicle includes a foundational body, a wheel engagement section extending a first distance from the foundational body, and a datum section including a protrusion extending a second distance from the foundational body. The wheel engagement section is configured to contact a wheel surface of the wheel assembly, and the datum section is configured to contact a pad of the wheel assembly. Additionally, the wheel engagement section is rigidly positioned with respect to the datum section, and the second distance is greater than the first distance, such that the maintenance assembly provides a fixed distance between a surface of the datum section configured to contact the pad and a surface of the wheel engagement section configured to contact the wheel surface.

A chassis (1) for a rail-bound transport vehicle for transporting goods, in particular in intralogistics. The chassis (1) has at least one chassis axle (2) and at least one load-bearing roller (3) configured for rolling on a rail (4) that is rotatably supported on a pivot arm (5) about a roller rotation axis (6) and the pivot arm (5) together with the roller (3) is pivotably supported by a pivot joint (7) on the chassis axle (2). The pivot arm (5) is additionally supported by a support bearing (8) on the chassis axle (2) and the roller (3) is arranged between the pivot joint (7) and the support bearing (8).

A wheel arrangement for a rail vehicle, such as a light rail vehicle, can include a wheel unit and an axle unit. The axle unit can be connected to a running gear structure of the rail vehicle. The axle unit can rotatably support the wheel unit. The axle unit can have a wheel bearing unit that forms a bearing for the wheel unit and defines a wheel axis of rotation of the wheel unit during operation of the rail vehicle. The axle unit can also have a wheel support unit and a primary suspension unit. The primary suspension unit can be located kinematically in series between the wheel support unit and the wheel bearing unit such that the wheel support unit supports the wheel bearing unit via the primary suspension unit in a manner resilient in at least two mutually transverse translational degrees of freedom.

The present disclosure relates to a welding base metal for recycling a railway wheel and a method for recycling a railway wheel using the same, which can overlay-weld a railway wheel with a welding base metal suitable for overlay-welding a railway wheel through a heat treatment, form a surface hardened layer, and strengthen the metal structure of the railway wheel, in order to recycle the railway wheel.

The welding base metal for recycling a railway wheel may be used as a surface hardened layer of a railway wheel because the welding base metal has high hardness while exhibiting a similar property to the railway wheel. Furthermore, the welding base metal can change the metal structure of the recycled railway wheel, and thus delay the initial wear time of the recycled railway wheel. The method for recycling a railway wheel may overlay-weld the damaged railway wheel to its original size, form a surface hardened layer, and change the metal structure of the railway wheel by changing the composition of the welding base metal and performing the pre-heat treatment and the post heat treatment, thereby minimizing the occurrence of damage to the recycled railway wheel.
