Bogie and guideway vehicle

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.

Methods and systems for dynamic weight management

A method for reducing slack in a linkage chain of a vehicle truck assembly is provided. In one example, the method includes responding to a request to de-lift a lift mechanism by reducing pressure in an actuator coupled to the lift mechanism, where the lift mechanism is configured to transfer a load from a first axle to a second axle of the vehicle during the de-lift, and during the de-lift, maintaining the pressure in the actuator at or above a threshold pressure to maintain tension in a weight transfer device of the lift mechanism.

Electric rail vehicle

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.

RAILWAY CAR TRUCK SYSTEM

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.

Chassis for rail vehicle

A chassis for rail vehicles includes at least one support structure, at least one first primary spring and a second primary spring, at least one first drive motor transmission unit connected to the at least one support structure via at least one first suspension element, at least one first wheelset and at least one first clutch connected to the at least one drive motor transmission unit and to the at least first wheelset, wherein the at least first drive motor transmission unit is connected to the at least one support structure via a coupling element that is loadable primarily in the direction of a chassis longitudinal axis so as to create advantageous construction conditions such that an advantageous movability of the support structure and the first wheelset relative to each other is achieved.

Methods and systems for dynamic weight management

Systems and methods for reducing slack in a linkage chain of a vehicle truck assembly is provided. In one example, a method includes compressing a vehicle suspension by actuating an actuator with a cylinder abutted to a piston rod, the piston rod coupled to the vehicle suspension and, when deactivating the actuator, maintaining at least nominal compression on the vehicle suspension with the piston rod spaced away from a piston of the cylinder via a biasing member, the piston configured to slide within the cylinder along a central axis of the cylinder.

Method for compensating for a loss of traction of a rail vehicle

A method for compensating for a loss of traction of a rail vehicle, preferably a freight locomotive, in a track curve, is particularly pertinent when the rail vehicle is starting up and/or is on an incline. Comparably unfavorable frictional conditions between a track and at least one driven track wheel of the rail vehicle are changed into comparably favorable frictional conditions by actively steering the track wheel on the rail.
