A bearing housing including a casing; a rotary bearing with an exterior race mounted inside a bore of the casing, an interior race adapted to be mounted on a shaft and rolling members between the races; and a cap fastened to a front-end face of the shaft, the cap forming an abutment for the interior race on the front face. The bearing housing also comprises a sealing ring mounted in the cap and intended to be clamped axially between the end face of the shaft and the cap.

A steering mechanism for a rail vehicle includes two steering arms, each including a pair of support arms that have a joining component with a recess. The two steering arms are articulated in a manner that maintains a minimum separation between the steering arms so that the arms can rotate relative to one another. The minimum separation is maintained by an insert that installs into the joining component recesses components of each of the steering arms. The insert has two sides, each side having a flexible material and forming a shape that mates with the recess. The insert provides resistance to the rotation between the first and second steering arms, and the resistance depends on the stiffness of the flexible material of the insert.

A vehicle guidance system and method of forming the same. The vehicle guidance system includes a transport guideway having an at least partial tube structure; vehicle tracks; a vehicle, having a fuselage with an uppermost surface and a lowermost surface, that travels over the vehicle tracks; and at least one track channel assembly arranged on an inside of the at least partial tube structure. The at least one track channel assembly is arranged so that, as the vehicle travels over the vehicle track, the at least one track channel assembly is located between the uppermost surface and the lowermost surface of the fuselage.

A railway-vehicles scalable tractive power system, integrated into all-wheel steering and braking systems to leverage synergies between plurality of differently designed electric traction-motors, electric steering motors and electric brake calipers; configured with plurality of sensors to eliminate wheel-dragging at virtually 100% dynamic efficiency. A fully automated electronic clutch-system attached to selected electric traction motors configured to perform above 90% traction efficiency by coupling to wheels selected electric traction-motors in their high efficiency range of operation, or de-coupling and replacing electric traction-motors with another electric traction-motors while the vehicle is changing speed or when it requires higher or lower tractive-power, from forward-motion start to top-rated speed. A holistic controller is configured with multi-objective optimization design (MOOD) procedures; measures complex variable parameters and values, finds the required trade-off among design objectives, and improves pertinence of solutions. Plurality of electronic-couplers is monitoring changing distance between wagons, whereas the controller is maintaining optimal ‘free-slack’ between wagons to prevent ‘run-in’ and ‘run-out’ scenarios with precise maneuverability between electric traction-motors actuation and electric brake-calipers actuation.

The electric vehicle can include: a payload interface, a payload suspension, a chassis, a set of bumpers, a sensor suite, a controller, a chassis suspension, and an electric powertrain. The electric vehicle 100 can optionally include a payload adapter, a power source, a cooling subsystem, and/or any other suitable components. The electric vehicle functions to structurally support a payload, such as a cargo container (e.g., intermodal container, ISO container, etc.), and/or to facilitate transportation of a payload via railway infrastructure.

An underneath type railway freight car bogie wheelset radial device has front and rear subframes and two cross-arranged connecting rods that are pinned by round pin connectors. The subframe is a combination structure of the adapter and the lateral arm. The connecting rods are arranged under the bolster to form the underneath bogie wheelset radial structure. The height of the central plane of the connecting rod is lower than the height of the central plane of the subframe adapter surface. The adapter has an adapter surface forming an arc-shaped adapter structure and an adapter connecting arm integrated with the adapter surface structure and vertically arranged at one end of the adapter surface; the subframes are fixed to the adapter by the rivet assembly.

The bogie includes: running wheels to be rolled on a road surface of guideway; an axle which is installed on a lower part of a body of a guideway vehicle and to which the running wheels are attached; a chassis supporting the axle; a guide device which is configured to be guided by the guideway and is installed on the chassis so as to be capable of turning around a turning axis extending in a vertical direction; a steering device which is configured to steer the running wheels in response to a turning movement of the guide device when the guide device is turned along a curved section of the guideway; and a tilting device which is connected to the guide device and which is configured to generate a tilting force of directing one side of the body located at an outside of the curved section upward with respect to the other side of the body located at an inside of the curved section in response to the turning movement of the guide device.
