A tubular elastic linkage device for axle beam for elastically linking a truck frame and an axle beam including: an inner axial member; two outer segments opposed in axis-perpendicular direction peripherally outside the inner axial member for attachment to a housing part on an axle-beam side; and a main rubber elastic body elastically connecting them. A pocket part opens in an outer peripheral face of the main rubber elastic body onto outside via a window penetrating one outer segment. A stopper supported by the inner axial member is disposed in the pocket part to face the housing part distantly via the window. Contact of the stopper with the housing part constitutes a displacement limitation mechanism between the inner axial member and the outer segments. The other outer segment has an aperture having the main rubber elastic body exposed outside via it.

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.

A wheelset guide for a rail vehicle, which has a bogie frame. Includes at least one longitudinal support, and includes a wheelset bearing for a wheelset of the rail vehicle, wherein the wheelset bearing is connected to the bogie frame and includes a rocker that is pivotably attached to the bogie frame via an elastic rocker bearing, and a pin guided by the rocker bearing, where the bogie frame forms a receptacle for the rocker bearing, which is configured such that the force is introduced into the bogie frame via the rocker hearing itself, and the rocker bearing is positioned in the receptacle in order to improve the strength and stability of the attachment of the rocker to the bogie frame or to the longitudinal support with an open profile.

A spring cup for a primary suspension of a rail vehicle, wherein the spring cup has a longitudinal axis and a spring base for transmitting occurring forces onto a chassis frame of the rail vehicle, and includes a spring seat for receiving at least one spring element, wherein the spring seat is supported against the spring base of the spring cup, where a central section of the spring seat is formed as a contact element having a contact surface for an emergency spring device, and the spring seat is configured such that a force acting on the contact surface is introduced into the spring base outside of the projection surface, resulting from the projection at least of the contact surface along the longitudinal axis onto the spring base in order to achieve a transfer of force from the center of the spring base.

The invention relates to a bogie for a rail vehicle characterized by a high lightweight construction potential. The bogie (1, 1*, 1**) according to the invention has, for primary suspension, a torsion spring system (12) in the inner volume of which a roll stabilizer having a torsion rod (11) is arranged in a torsionally movable manner. The roll stabilizer can be articulated to the car body of the rail vehicle or to the torsion spring system (12). The bogie (1, 1*, 1**) according to the invention advantageously has a particularly large installation space for built-in components.

A railcar bogie includes: a cross-beam supporting a carbody; pair of axles at both cross-beam sides in car longitudinal direction and extending in car-width direction; bearings at both car-width direction sides of each axle and rotatably supporting axles; axle-boxes accommodating respective bearings; plate-springs supporting both car-width direction end-portions of the cross-beam and extending in car longitudinal direction, both car longitudinal direction end-portions of each plate-springs supported by axle-boxes; pressing members at both car-width direction end-portions of the cross-beam placed on respective car longitudinal direction middle-portions of plate-springs, lower surface of a portion of each pressing member having a convex downward circular-arc shape in side-view, the portion pressing the plate-spring, a middle-portion upper surface of each plate-spring having convex downward circular-arc shape in side-view, the middle-portion pressed by the pressing member, and a lower surface curvature of the pressing member larger than the upper surface curvature of the middle plate-spring portion.

The invention relates to bogies for railway vehicles with at least two wheelsets mounted in axleboxes and at least one transverse member. The bogies are in particular characterized in that they have a lightweight design and can be produced at low cost. The axleboxes of a wheelset are articulated to the transverse member via two axle levers so that the axle levers form an H shape with the axleboxes and the transverse member. The transverse member has at least two torsion bars arranged in parallel to the axles of the wheelsets, said torsion bars being firmly connected to the transverse member. The torsion bars have spring levers so that the end portion of the spring lever not connected to the torsion bar acts upon the axlebox.

A running gear unit for a rail vehicle, having a running gear frame body. The frame body includes two longitudinal beams and a transverse beam unit providing a structural connection between the longitudinal beams, such that a substantially H-shaped configuration is formed. Each longitudinal beam has a suspension interface section associated to a free end section of the longitudinal beam and forming a primary suspension interface for a primary suspension device. Each longitudinal beam has a pivot interface section associated to the primary suspension interface section and forming a pivot interface for a pivot arm. The primary suspension interface is configured to take a total resultant support force acting in the area of the free end section when the frame body is supported on the associated wheel unit.
