摘要： A steerable truck for a railway car is provided with a truck frame that is steered so as to be aligned with the tangential direction of a curved track by controlling only the steering angle of a rear wheelset. During travel along a curved track, the steering angle, which is the angle in a horizontal plane of the centerline of the rear wheelset with respect to an imaginary straight line connecting the center of the truck frame and the center of the curved track, is larger than the steering angle which is the angle formed between the imaginary straight line and the centerline of the front wheelset. As a result, a steerable truck for a railway car which has excellent ability to travel along a curve and which can be actually realized simply and at a low cost is provided.

摘要： A method for limiting the angle between the longitudinal axes of car bodies of a multi-part rail vehicle connected to each other via a joint, wherein each car body is supported on only one bogie. The angle is actively influenced by an electrically controlled activation member connected to the joint, until the angle assumes a setpoint value. The setpoint value is determined from the pivot angles (relative angles) of the bogies relative to the associated car bodies.

摘要： A railway truck has a frame, and two wheel-sets operatively connected to the frame. Each wheel-set includes a corresponding axle, and two wheels disposed on the axle. A first steering lever is pivotally connected to the first end portion of the first axle about a first pivot axis and to the frame about a second pivot axis. A second steering lever is pivotally connected to the second end portion of the first axle about a third pivot axis and to the frame about a fourth pivot axis. A first line passing through the first and second pivot axes crosses a second line passing through the third and fourth pivot axes at less than a predetermined distance from a vertical centerline of the truck when the first and second axles are parallel. A railcar including the truck is also provided.

摘要： A rail vehicle undercarriage comprises a load bearing implement 1 in the form of the bogie frame of a two-axle bogie, wherein the load bearing implement 1 is supported on two wheel pairs 4, 4; 4, 4 by means of spring elements 2. One respective steering rod 9 that extends in the running direction of the wheels is provided per wheel 4, wherein said steering rods are coupled to the wheel carrier 3 adjacent to the corresponding wheel 4 with one end and to the load bearing implement with their other end in coupling points 8, 10. The wheel pairs can be turned relative to the load bearing Implement. In order to achieve a turning movement of the wheel pairs towards a curve-radial adjustment which depends on the curve radius of the currently used track, the respective steering rods 9 are directly coupled to the load bearing implement 1 in coupling points 10. In addition, the coupling points 10 of the steering rods 9 of at least one wheel pair 4, 4 are, referred to the plane defined by the contact points 6 between the wheels 4 and the rails 7, situated above the coupling points 8 of the steering rods 9 on the corresponding wheel carrier 3 when the steering rods 9 point toward the central region between two wheel pairs in the running direction of the wheels.

摘要： A steerable truck apparatus for railroad cars for providing for the controlled and uniform yawing of the axles of the truck. The truck apparatus provides for a yawing response which is linear substantially throughout the range of movement of the axles. The truck is further configured with pivotably supported pedestals for equalized load distribution. An improved axle bearing construction accommodates pivoting of at least one of the axle ends. A damping apparatus provides stiffness in the steering response toward reducing hunting of the wheels during straight line travel.
