    摘要： A railcar bogie includes: a bogie frame including a cross beam supporting a carbody of a railcar; a pair of axles respectively arranged at both sides of the cross beam in a car longitudinal direction and extending in a car width direction; bearings provided at both car width direction sides of each of the axles and rotatably supporting the axles; axle boxes respectively accommodating the bearings; and coupling devices coupling the axle boxes and the bogie frame to one another, each of the coupling devices including a first member projecting from the axle box to the bogie frame, a second member projecting from the bogie frame to the first member, and a coupling portion coupling the first member and the second member to each other, and the second member being formed separately from the bogie frame and positioned by contacting the bogie frame.

    摘要： A railcar bogie includes: a cross beam extending in a car width direction and supporting a carbody; plate springs extending in a car longitudinal direction and supporting both respective car-width-direction end portions of the cross beam; axle boxes accommodating respective bearings for axles and supporting respective car longitudinal-direction end portions of the plate springs; plate spring receivers each located between the plate spring and the axle box and including an upper surface which is inclined toward a longitudinal-direction middle portion of the plate spring, the upper surface receiving the plate spring; and stoppers arranged so as to cover at least a part of an upper surface of the plate spring, the part being located above the axle box.

    摘要： A wheel set for a rail vehicle, in particular for a locomotive, includes two track wheels which are connected by a wheel axle mounted in two wheel set bearings. Each wheel set bearing includes a cast bearing housing, which is closed by an outer housing cover and an inner pressure ring. In addition, the bearing housing has a clamping position for engaging a tensioning device of a machine tool for machining the wheel set. Since the clamping position is integrated in the pressure ring, the clamping position can be easily cut to size and the bearing housing can be produced in a weight-optimized and cost-effective way in comparison to known bearing housings.

    摘要： A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal self steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and those auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behavior. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slope face, or both. The friction dampers may operate to yield upward and downward friction forces that are not overly unequal. The friction dampers may be mounted in a four-cornered arrangement at each end of the truck bolster. The spring groups may include sub-groups of springs of different heights.
