摘要： There is provided a self-steering truck in which travel stability and turning performance are improved, and a railroad vehicle to which the self-steering truck is applied. An active steering damper 10 is extended or shrunk as a whole by driving a DC motor 13 so as to rotate a ball screw 15 and allow a nut 16 into which the ball screw is engaged to spiral back and forth, and thereby wheel axles 2 are steered through a steering link 6. This steering is performed by the active function of the active steering damper 10. The active function can solve the response delay of the self-steering which occurs while moving from a straight line to a steady curve through a transition curve. The active steering damper 10 also has a passive function. The passive function serves as a rigid body with respect to vibration at a frequency of hunting which occurs at the time of moving along a straight line, and exerts a buffering function as a non-rigid body with respect to vibration at another frequency. With this, high-speed travel in a straight line and moving performance along a steady curve can be improved.

摘要： A linear steering truck apparatus (10) comprises a bolster member (20) having two ends. The bolster (20) is located along the transverse axis extending generally perpendicular to the longitudinal axis, and generally located between and parallel to the transversely extending axles (14,16). Side bearings 32,34 attach the linear steering truck (10) to the car body (12). A plurality of pedestals (26,27,28,29), each engages an axle bearing (30). The axle bearing (30) rotationally engages one end of a transversely extending axle (14,16). At least one pedestal (26-29) is movably attached to at least one other pedestal (26-29) situated in the same plane along the longitudinal axis. Steering component (90) is provided for performing car body steering, where the geometry of pivot points (63a,63b) from another axle to the bolster (20) forms a parallelogram. The pedestals (26-29) are pivotally connected so that a lateral force at one axle (14,16) is reacted by the other axle (14,16), wherein the car body (12) mass acts as a pendulum mass restoring force. The apparatus (10) is steered to the center of the track with either end of the truck leading after the trapezoid side yaws.

摘要： The invention relates to a running gear for rail vehicles, especially for passenger traffic, wherein a frame (1) is supported, by means of primary springs, on wheels or sets of wheels, and whereon a superstructure (5) is supported, optionally with insertion of a bolster (4). The bolster (4) or the superstructure (5) is supported by means of secondary springs, in relation to the frame (1), on at least one spring carrier (2), the bolster (4) or the superstructure (5) is connected to the frame (1) by means of a shock absorber used to damp vertical and/or rolling movements, and the spring carrier (2) is suspended on the frame by means of pendulums (3). The fixing points of the pendulums (3) on the running gear frame (1) are inwardly staggered, unlike vertically arranged pendulums, in such a way that the longitudinal axes of the pendulums (3) extend diagonally. At least one active control element (7) is at least partially arranged in the horizontal direction between the frame (1) and the spring carrier (2) or between the frame (1) and the bolster (4), in such a way that it supports the effect of the centrifugal force and adjusts the incline to an optimum value.

摘要： A side frame (8) for a railway car comprises a pedestal jaw (10) and an integral crown shaped pedestal jaw roof (20). A snap-on liner (28) matching the shape of the crowned pedestal jaw roof (20) is removably mounted to the pedestal jaw roof (20). In operation, the crown shaped pedestal jaw roof (20) and snap-on liner (28) reduce wear on the pedestal jaw roof (20) and permit swinging of the side frame (8) relative to railcar axles. The integral crown shaped pedestal roof (20) and snap-on liner (28) eliminate the traditional rocker seat, shims, and welded retainers, thereby reducing the maintenance and cost of traditional side frames.

摘要： A lightweight truck bolster (10) for railway car trucks has metal removed in the compression member (18) and tension member (20) of the bolster (10) near the center bowl (12) of the bolster (10). The bolster (10) includes one longitudinal rib (48) located in each end of the bolster arms (14, 16) and a pair of transversely extending vertical ribs (30) located on opposing sides of the center bowl (12) and extending from the tension member (20) to the compression member (18). The bolster (10) satisfies the Association of American Railroads (A.A.R.) design qualifications for truck bolsters while it is weighing significantly less than traditional truck bolsters.

摘要： The present invention relates to a damper arrangement for a rail vehicle (101), in particular, a light rail vehicle, comprising a damper unit (106), wherein the damper unit (106) comprises a piston unit (106.1) and a cylinder unit (106.2) defining an axial direction and a radial direction. The cylinder unit (106.2) comprises a sealingly closed working chamber (106.3) filled with a damping fluid (107) and axially slidably receiving a piston element of the piston unit (106.1), wherein the piston element separates the working chamber (106.3) in a first space (106.5) and a second space (106.6). The piston unit (106.1) has a first interface part (106.7) forming a first interface of the damper unit (106) to a first vehicle component (102.1) of the rail vehicle and facing away from the cylinder unit (106.2). The cylinder unit (106.2) has a second interface part (106.8) forming a second interface of the damper unit (106) to a second vehicle component (102.1) of the rail vehicle and facing away from the piston unit (106.1). A damper support unit (108) supports the damper unit (106), wherein the damper unit (106) is configured to provide a damping force damping a relative motion between a third vehicle component (103.4) connected to the damper support unit (108) and at least one of the first vehicle component (102.1) and the second vehicle component (102.1) along the axial direction. The damper support unit (108) restricts motion of the piston unit (106.1) with respect to the damper support unit (108) in a first direction along the axial direction while allowing motion of the piston unit (106.1) in an opposite second direction along the axial direction. The damper support unit (108) restricts motion of the cylinder unit (106.2) with respect to the damper support unit (108) in the second direction while allowing motion of the cylinder unit (106.2) in the first direction. The piston element (106.4) defines a radial gap (G) with respect to the cylinder unit (106.2) in the radial direction, the radial gap (G) restricting flow of the damping medium between the first space (106.5) and the second space (106.6) in order to provide a defined dynamic characteristic of the damping force which is dependent on a speed of a relative motion between of the piston element (106.4) and the cylinder unit (106.2) along the axial direction.
