  • Patent number: 6289821
    Abstract: The rail vehicle, especially for a streetcar or metropolitan transit car for local traffic, includes a car body (1) and an undercarriage (2) nonrotatably connected with each other by respective guide rods (3) each extending in a longitudinal direction. The connector members (3a) of these guide rods (3) facing the car body (1) and the corresponding receptacles (4) for them attached to the car body are arranged together in the central plane (M) of the undercarriage, which extends perpendicularly to the vehicle longitudinal axis (L). The connector members (3a) and the corresponding receptacles (4) are arranged together in the central plane (M) in a symmetrical arrangement so that a rapid reversal of the running direction of the undercarriage may be performed by only releasing the guide rods from their receptacles, rotating the undercarriage by about 180° and reconnecting the guide rods to the receptacles without moving the undercarriage from the first head end to the second head end of the car body (1).

  • Patent number: 5327837
    Abstract: A bolster for a railroad car truck is described as having a generally hollow, box-like construction between its opposing ends which are transformed into I-shaped sections which are rigidly secured to the sideframes. The box-like frame provides the stiffness or rigidity necessary to resist high vertical and longitudinal loads which can cause the bolster to bend during operation of the truck. The I-shaped sections are relatively more flexible than the box-like frame to accommodate or absorb the twist loads that are encountered while being rigid enough to resist the loads that can cause the bolster to bend.

  • Patent number: 4411202
    Abstract: The rail vehicle has two bogies each connected to the vehicle body by way of a single rod adapted to transmit traction and braking forces. The rods are disposed in the longitudinal center-plane of the body and are articulated to the body at one end and to the particular bogie at the opposite end. The rods are at an inclination such that the imaginary extension of the longitudinal axis of each rod intersects the transverse center-plane of the particular bogie concerned at a distance below the plane of the rail-top surfaces. To an extent corresponding to the distance, the axle loading of the leading wheel set of the leading bogie becomes greater than the axle loading of the second wheel set, thus compensating for the effect of reduced friction between the leading wheel set and the rails in bad weather conditions.

    Abstract: A pair of mechanical springs are disposed on an air spring on each side of a truck carrying a car body. A wide plank disposed between the pairs of mechanical springs and each of the air springs is pivoted to permit vertical movements without tilting of the air springs when the mechanical springs are deflected laterally. Shock absorber means are connected between the car body and bolster along the longitudinal axis of the bolster to control lateral shocks as when the mechanical springs are laterally deflected.Mechanical springs in railway cars have employed pairs of mechanical springs in series with pneumatic springs. Multiple mechanical springs, in series with pneumatic springs, have included a heavy outer coil spring and an inner lighter coil spring coaxially nested with the heavy outer spring used to keep the stress levels on the individual springs relatively low. This arrangement is illustrated in U.S. Pat. 3,491,702 to A. G. Dean entitled "Series Pneumatic and Coil Spring Assembly".
