摘要: A method for improving the curvilinear running speed of railway vehicles and the small tilting system: when the railway vehicle is driven on a curve, the raising and falling of air springs on both sides of the railway vehicle are controlled by a control assembly to realize small tilting of the railway vehicle toward the inner side of the curve; the transverse component of gravity after the small tilting of the railway vehicle is used for balancing part of the centrifugal force and reducing the influence of the centrifugal force, thereby improving the curve driving speed of the railway vehicle; and at the same time, an adjustable torsion bar system is controlled to provide a unidirectional anti-rolling torque for preventing the railway vehicle from rolling toward the outer side of the curve without hindering the railway vehicle from tilting slightly toward the inner side of the curve.

摘要: A bogie for a railway vehicle includes a frame, which has a first side beam and a second side beam extending along a longitudinal axis of the bogie and spaced apart from each other. A secondary suspension system is located on the frame and includes a first suspension assembly, which includes a first air spring and a first auxiliary spring positioned at the first side beam. The first air spring is positioned below and is arranged to be pressurized for supporting the body of the railway vehicle above the frame. The first auxiliary spring is fixed to an upper side of the first side beam underneath and spaced apart from the first air spring. The first suspension assembly further includes a first force-transmission mechanism configured to transmit forces exerted by the body on the first air spring to the frame via the first auxiliary spring.

摘要: A symmetrical multi-unit railroad freight car, such as a 3-pack railroad intermodal well car, has body units that are connected symmetrically. The body units have a symmetrical arrangement of end trucks and shared trucks. The end trucks are 70 Ton Trucks. The shared trucks are 125 Ton trucks. The trucks have passive steering using geometric rocker stiffnesses. The rockers in the end trucks have a smaller radius of curvature than the rockers in the shared trucks. The spring groups in the shared trucks are stiffer than the spring groups in the end trucks. The spring groups in the end trucks have a different proportion of damping when empty, a shorter live load range of travel, and greater reserve travel than the shared trucks. The end trucks and the shared trucks have four-cornered damper groups that have the same sized damper wedges. The damper wedges have non-metallic wear pads.

摘要: 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.

摘要: 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.

摘要: Vehicles for use on a railway and their methods of operation are disclosed. In one embodiment, a vehicle includes a bogie with wheels engaged with opposing tracks extending along a length of a railway the bogie travels along. The vehicle includes at least one sensor configured to sense a position of the bogie and/or wheels relative to the tracks of the railway. A processor of the vehicle uses the sensed position of the bogie and/or wheels relative to the tracks to steer the wheels of the bogie along a desired path on the tracks as the bogie travels along the railway.

摘要: A railroad car truck bolster including a first end, a first diagonal member, a transitional concave first turn of spring seat, a center rib assembly, first and second diagonal ribs, and a bottom member. The center rib assembly includes first, second, and third center ribs and a U transition. The bottom member includes thickened walls that define brake rod holes. The first diagonal member is connected to the first end via the concave first turn of spring seat. The center rib assembly is connected to the first end, the straight first diagonal member, and the first turn of spring seat. The first, second, and third center ribs are connected to one another via the U transition. The first and second diagonal ribs are connected to the first turn of spring seat. The third center rib is between the first and second diagonal ribs. The bottom member is connected to the first diagonal member.

摘要: A carbody support device of a railway vehicle, including support mechanisms installed between a front bogie and a carbody and between a rear bogie and the carbody in a traveling direction, and supporting the carbody against the respective bogies. The support mechanisms regulate both the front bogie and the rear bogie inclining in the same vehicle width direction with respect to the carbody when the railway vehicle travels through a curve, while the support mechanisms permit the front bogie and the rear bogie inclining in different vehicle width directions.
