A bogie for a railway vehicle 1 includes an elastic element 20 that is arranged between a vehicle body 7 and a bogie frame 3 of a railway vehicle and elastically supports both, and the elastic element 20 is configured in such a manner that a spring constant for displacement in the longitudinal direction in the traveling direction of the vehicle body 7 is smaller than that for displacement in the vertical direction or the left-and-right direction in the traveling direction.

A steering system for a locomotive truck may include a first axle and a plurality of primary bearing adapter assemblies, each primary bearing adapter assembly may include a bearing adapter and a swiveling back plate, wherein each bearing adapter may be disposed around the first axle.

Railway system includes a railway vehicle movable along a railway guide system, the railway vehicle including a chassis and a carriage rotatably supported on the chassis via a pivot coupling. The railway vehicle further includes a pivot actuation system including an actuator and a control system connected to the actuator and to sensors for actuation and control of the rotation of the carriage relative to the chassis. The carriage is rotationally supported relative to the chassis about a pivot axis (P) that remains in a static position with respect to the chassis, the carriage having a mass distribution forming a centre of gravity (CG) positioned below the pivot axis (P), the pivot actuation system serving to assist and dampen passive rotation of the carriage relative to the chassis due to the torque generated by centrifugal force acting upon the centre of gravity about the pivot axis (P).

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.

A chassis (1) for a rail-bound transport vehicle for transporting goods, in particular in intralogistics. The chassis (1) has at least one chassis axle (2) and at least one load-bearing roller (3) configured for rolling on a rail (4) that is rotatably supported on a pivot arm (5) about a roller rotation axis (6) and the pivot arm (5) together with the roller (3) is pivotably supported by a pivot joint (7) on the chassis axle (2). The pivot arm (5) is additionally supported by a support bearing (8) on the chassis axle (2) and the roller (3) is arranged between the pivot joint (7) and the support bearing (8).

A failure determination device includes an acquirer to acquire pressure values of air springs provided to bogies included in a vehicle to support a vehicle body included in the vehicle, a compensator to perform compensation of the pressure values of the air springs depending on the position of the vehicle, and a determiner to determine, based on the pressure values of the air springs compensated by the compensator, whether any failure occurs in the air springs.

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.
