Disclosed is a hydraulic bushing and a rail vehicle. The hydraulic bushing comprises: a core shaft; a sleeve mounted on the core shaft, wherein a first rubber body is filled in a space formed between the core shaft and the sleeve, and a groove is provided on an outer surface of the sleeve; and an outer housing, which is mounted on the sleeve through press fit. Two liquid chambers for accommodating liquids are provided diametrically opposite to each other on the first rubber body, and the groove and the outer housing together define a flow channel, through which the two liquid chambers communicate with each other. Use of the hydraulic bushing on the rail vehicle not only can assure stable operation of the vehicle in a straight running state thereof, but also can reduce abrasion of a wheel and a rail in a curve running state.

A magnetic elevated wheel assembly of a vehicle may include at least one wheel mounted on an axle, at least one magnet mounted on at least one of the axle or a vehicle body, and a shell connected to the at least one wheel. The shell may extend from the at least one wheel in an axial direction and may be positioned radially outward of at least a portion the at least one magnet. The at least one magnet may be configured and oriented to generate a magnetic force acting on the shell to elevate at least a portion of a weight of the vehicle acting on the axle to balance a rolling resistance acting on the at least one wheel.

A friction apparatus is provided. The friction apparatus includes: a first member having a first surface; and a second member having a second surface that contacts the first surface, and moving while in contact with the first member, wherein at least one of the first surface and the second surface is hardened.

A rail cum Road Vehicle (RCRV) running on rail tracks or on plain roads, includes a gas powered hybrid engine coach linked to and pulling one or several passenger coaches or goods vehicles, all of which in common are fitted with pneumatic rubber wheels, steel wheels, air suspension system with hanger brackets, air brakes and couplers.

A solid wheel for a rail vehicle includes a wheel rim arranged on the circumference of the solid wheel, a tread and a hub for a wheelset shaft, wherein the wheel rim is connected to the hub via an end wall and a rear wall, where the hub is arranged at the center of the solid wheel and includes a longitudinal axis such that a high radial and axial strength of the wheel flange as the basis for a low sound emission is provided by virtue of the solid wheel forming a cavity that is delimited by the end wall and the rear wall, where the end wall and the rear wall transition into each other below the wheel flange in an arched manner, and the end wall has first openings and the rear wall has second openings in order to open the cavity outwards in a spoked manner.

A vibration and noise damper for wheels of rail vehicles, to which wheels it is fastened with screws, pins, or rivets, which comprises of at least two segments formed by a supporting part (2) for gripping to the wheel (1), a pushing part (3) and a damping part (4), where the pushing part (3) is connected by means of bolts (9) with the supporting part (2) and is formed either by a single metal or composite element, or it is directly integral part of the damping part (4) and where the damping part (4) is formed in the direction away from the wheel (1) rim of a strain pliable metal or composite layer (4a), of a viscoelastic layer (4b), and possibly of other metal or composite layer (4c), wherein in compressed state the damping part (4) is placed between the pushing part (3) and the wheel (1) rim. Preferably, the supporting part (2) is formed of metal or composite material. Also preferable is the embodiment when thermally insulating pads (5) are arranged between the supporting part (2) and the wheel (1) and/or between the fastening material for attaching the supporting part (2) to the wheel (1) and the wheel (1). The viscoelastic layer (4b) in the damping part (4) can comprise glass fibers and/or ceramic fibers and can be provided with a set of holes (4d) and/or radial cuts (4e) of various shape, wherein their number, size and arrangement are different for individual designs of the dampers in relevance to their shape.

A backing ring assembly is for railway axles and includes a backing ring and an annular insert having L-shaped axial cross sections. The insert includes a sleeve portion fitted to a radially outer cylindrical surface of the backing ring, which delimits a first axial section thereof. The annular insert sleeve portion includes first and second axial sections hingedly connected by an intermediate, reduced thickness section designed to form a plastic hinge. The first axial section of the sleeve portion projects axially from the first section of the backing ring, which is provided with an annular projection designed to induce elastic deformation of the reduced thickness section to ensure that the second axial section of the sleeve portion is always coupled with the cylindrical outer surface of the backing ring first axial section by an interference fit.
