摘要： A bolster beam is correspondingly connected to a connection base by means of a damping unit; the radial dimensions of an outer wall of an inner supporting member and an inner wall of an outer supporting member gradually decrease from one end to the other end in a vertical direction; one of the inner supporting member and the outer supporting member is connected to the connection base, and the other one is connected to the bolster beam; when in use, the inner supporting member and the outer supporting member tend to be close to each other, and since surfaces, close to each other, of the two are configured to be tapered, the two can-not be relatively separated; when getting closer to each other, the inner supporting member and the outer supporting member produce a compression action on an intermediate buffer member, and the intermediate buffer member is elastically deformable.

摘要： Disclosed is a bolster of a bogie, wherein a secondary suspension connected with a transverse beam of the bogie is arranged below the bolster, and a third suspension connected with a vehicle body is arranged above the bolster. The bolster of the bogie of the present invention realize a functional separation by adding a suspension between the bottome of the bolster and the transverse beam to make the frame and the vehicle body be connected through a two-stage suspension, so that the third suspension above the bolster is only used to undertake a transverse displacement function, and the secondary suspension under the bolster is only used to undertake a rotation function, thereby further increasing displacement and relative rotation angle between the vehicle body and the bogie when the vehicle passes through a curve, and improving curve passing capability of the vehicle.

摘要： A device transmits a force between a chassis and a body of a rail vehicle. The device is a structurally simple, space-saving device which allows spring movements and rotational movements of the body relative to the chassis. This is achieved in that at least one first traction link buffer, which has a first end face, and at least one second traction link buffer, which has a second end face, are fixed to the chassis. The first end face is spaced from the second end face in a longitudinal direction of the rail vehicle. The two end faces point in at least approximately opposite directions, and a stop plate with sliding portions which are mutually spaced in the longitudinal direction is provided on the body. The end faces of the traction link buffers rest against the sliding portions in a slidable manner at least along some sections.

摘要： A railroad car bolster with provision for elastomeric cushions or pads on each side of the bolster center plate. The pads are mounted in retainers. The side walls of the retainers extend upwardly from the bolster and have substantially continuous uninterrupted upper surfaces. The pads positioned within the retainers have elongated slots which extend along and are slightly spaced from the retainer side walls. Fastening members, in the form of angles, are welded to each retainer side wall, and have a portion thereof which extends along the flat upper surface of the side wall and into the pad slots to thereby secure the pads within the retainers.

摘要： This application discloses a railway vehicle truck of a general configuration having independently movable side frames, wherein the side frames are provided with resilient connections with the wheel-axle units which allow universal turning movement but substantially inhibit relative axial movement; wherein the side frames are connected at longitudinally spaced points by transverse cross-frame or transom bar members which are rigidly connected to the side frames at one end and connected to opposite side frames by true turning shaft-bearing joints which also, when needed, provide limited axial movement, the shaft-bearing joints having axes disposed on a line passing through the vertical axis of turning of the truck whereby the transom bars positively maintain the truck in tram; wherein a center frame is mounted at longitudinally spaced laterally central points on the transom bars by resilient joints which are spaced approximately the same distance from the transverse vertical central plane of the truck as the shaft-bearing turning joints of the transom bars on the side frames, the resilient joints providing considerable vertical turning movement but restricting direct vertical movement; wherein the center frame provides a true turning shaft-bearing joint with the truck bolster; wherein the truck bolster is turnably supported by resiliently backed bearing plates on supporting surfaces on the side frames; wherein the vehicle body is supported by air springs located directly upon and above the side frames, the air springs being of a type to assist materially in controlling transverse movements and, in conjunction with air reservoirs and suitable orifice or valve means to assist in controlling vertical ride dynamics of the vehicle; wherein a frame carrying a drive motor and axle drive means is supported by the center frame in such manner that the movements of the motor frame are kept within proper limits relative to the axles; and wherein a transverse anti-roll bar suspension is provided to control roll dynamics of the truck bolster and the vehicle or car body carried thereon.

摘要： A suspension for a high-speed railway vehicle comprises between the body and the bogie chassis a bolster platform which is connected to the body by a pivot allowing the free rotation of the bogie in the curves, in combination with springs. Moreover, the bolster platform is connected to a transom of the bogie chassis by an articulated trapezium, with springs ensuring the stability. The body can thus orientate itself in the direction of the centrifugal force in the curves without loss of the stability. The articulations of the trapezium are situated very low, which reduces to a minimum the dynamic transfers to the axles.
