A power generator assembly including a rotating part and a non-rotating part is provided. It is proposed that the rotating part includes first and second, circumferentially adjacent generator units. Each generator unit includes at least one coil, at least one permanent magnet and two pole shoes having pole surfaces facing radially outward. The non-rotating part includes an arc-shaped saddle adaptor of ferromagnetic material arranged with a radial distance to the pole surfaces. The saddle adaptor is configured to close a magnetic circuit passing via the pole shoes through the coil in a rotational position where the saddle adaptor overlaps with the pole shoes of a generator unit. According to the invention, a pole shoe of the first generator unit and an adjacent pole shoe of the second generator unit have the same magnetic polarity.

A maglev vehicle and a suspension frame assembly thereof. The suspension frame assembly includes multiple suspension frames sequentially connected to each other. Each suspension frame comprises two motor beams, four support arms, and four air springs. An air spring mounting seat is disposed at a top portion of each support arm. The air spring mounting seats are cavities having openings. The air springs are accommodated in the respective cavities.

A railcar bogie includes: a bogie frame including a cross beam and plate springs and being rotatable relative to a bolster in a yawing direction, the cross beam extending in a car width direction, the plate springs supporting both respective car width direction end portions of the cross beam and extending in a car longitudinal direction; and stoppers provided at the bogie frame and configured to contact interference members to restrict a rotation range of the bogie frame when the bogie frame rotates relative to the bolster in the yawing direction, the interference members being connected to the bolster. When the bogie frame is located at a neutral position relative to the bolster in the yawing direction, the stoppers are arranged at car width direction lateral sides of the cross beam so as to overlap the cross beam in a side view.

A railcar bogie includes: a bogie frame including a cross beam and plate springs, the plate springs supporting both respective car width direction end portions of the cross beam and extending in a car longitudinal direction; axles extending in a car width direction; bearings provided at both respective car width direction sides of each of the axles; axle boxes accommodating the respective bearings and supporting the plate springs from below; and rubbing plates provided on an upper surface of the bogie frame to slidingly contact respective rubbed plates provided on a lower surface of a bolster. In a plan view, each of the rubbing plates is arranged within a region where the cross beam and the plate spring intersect with each other and is arranged on a center line of the plate spring, the center line extending in the car longitudinal direction.

A side bearer of a railcar truck is designed to limit reciprocal displacement of a truck and railcar under a frame. The side bearer includes a carrying body with a guiding opening wherein a bearing cup is mounted by applying a springing element. A thrust collar is implemented on a guiding wall in a groove. Upon off-loading the cup e.g., during dismantling of a truck from under a railcar, a thrust collar bears against a limiting face ensuring unreleasable connection of the side bearer. Indicator grooving is implemented on a working face and on a lateral wall of a carrying body, enabling visual control of a side bearer technical condition.
