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 behaviour. 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.

A railway truck frame (20) for a railway truck including a first side frame (50) and a second side frame, each side frame having an inverted trapezoidal-shaped window (68) including a first inclined side and a second inclined side. The truck frame also includes a bolster (54) having a first end and a second end which extends transversely between the first and second side frames. Each end of the bolster includes a first inclined channel and an opposing second inclined channel. Each channel includes an exterior flange, a spaced apart interior flange, and a bearing surface located between the exterior and the interior flanges. Each inclined side of a window is adapted to be located in a respective first or second channel between the exterior flange and the interior flange ofthe channel and in engagement with the bearing surface of the channel. A locking device (180) such as a jack is located in each window between the top of the end of the bolster and the top side (78) of the window which selectively forces the end of the bolster downwardly into engagement with the side frame such that the end ofthe bolster is rigidly but removably connected to the side frame.

Aufhängung für Fahrzeuge zwischen einer abgefederten Fahrgastkabine und einem nichtabgefederten Fahrgastgestell mit mindestens einer weichen Feder und einem parallel zu ihr geschalteten Dämpfungsglied. Letzteres ist ein aktives Dämpfungsglied mit steuerbarem Dämpfungsgrad, das einen Hydraulikkolben, einen ersten Bypass mit konstanter Drosselwirkung und einen zweiten Bypass mit Drosselventil aufweist, wobei das Drosselventil mit einer Steuervorrichtung verbunden ist, die es als Funktion der Auslenkungsgeschwindigkeit der weichen Feder oder der seitlichen Beschleunigungswerte der Fahrgastkabine und des Fahrgestells öffnet oder schließt.

摘要:
The present invention relates to a running gear unit for a rail vehicle, comprising a running gear frame unit (104), a traverse unit (109), and a suspension unit (106), in particular, a secondary suspension unit. The running gear frame unit (104) is configured to be supported on at least one wheel unit and defines a longitudinal direction, a transverse direction and a height direction. The traverse unit (109) is configured to support a wagon body (101.1) unit of the rail vehicle. The suspension unit (106) suspends the traverse unit (109) to the running gear frame unit (104). The suspension unit (106) comprises at least one spring unit (110) and at least one pendulum unit (111) arranged kinematically in series in a force flux between the running gear frame unit (104) and the traverse unit (109). The at least one pendulum unit (111) has a first end section with a first articulation (111.3) associated to the running gear frame unit (104) and a second end section with a second articulation (111.4) associated to the traverse unit (109). The first articulation (111.3) and the second articulation (111.4) allow relative motion between the running gear frame unit (104) and the traverse unit (109) in the transverse direction and/or in the longitudinal direction by a pendulum motion of the pendulum unit (111). The first articulation (111.3) and/or the second articulation (111.4) is formed by the at least one spring unit (110).
