| 摘要 |
The invention relates to a truck for a railway vehicle, especially a high-speed railway vehicle, comprising a truck frame (3) and a bolster beam (4) that extends perpendicular to the direction of the truck and is used for supporting a body. One respective spring support (9) is fastened to the truck frame (3) perpendicular to the direction of the truck on both sides of the center of the truck frame by means of at least one inclined swing link mechanism that is hinged to the truck frame (3) and the spring support (9). The bolster beam (4) rests on the respective spring support (9) via at least one secondary spring mechanism. In order to increase ride comfort at high running speeds without substantially affecting the sound-proofing properties or increasing the structural height of the undercarriage, the secondary spring mechanism of the inventive truck is provided with at least one conical spring element (7) which extends across 80 to 95 percent of the distance between the bolster beam (4) and the spring support (9).
