Inventor: LANG HANS PETER
IPC: B61F5/06
Filed: 1990-11-27
Abstract: In a railway vehicle with a secondary spring arrangement acting between the chassis and the vehicle body which generates a continuously increasing restoring moment at a relative inclination between the two units until the maximum permissible angle of roll is reached, according to the invention a permissible limitation of the angle of roll is achieved without any adverse effect on the derailing limit and ride comfort on straights in a structurally simple and reliable manner, in that the spring arrangement is comparatively soft and there is a passively acting supplementary spring with a limited range of rotation (rotation play coupling) connected in parallel to the spring arrangement, which operates virtually without restoring moment in a partial range of slight roll angle movements, and at greater deviations of the roll angle within the permissible range, generates a steeply increasing restoring moment which is many times greater than that of the spring arrangement at the maximum permissible angle of body roll.
