Abstract
In a coupling of an axle member to a vehicle leaf spring or a longitudinal link, the axle member is coupled to a vehicle leaf spring or a longitudinal link with spring/damper elements therebetween. Arranged between the axle member and the vehicle leaf spring or the longitudinal link are at least two spring/damper elements, which, in the direction of travel, are arranged in front of and behind the section of the axle member to which the leaf spring or the longitudinal link is coupled. The stiffness of the spring/damper elements is greater in the horizontal directions than in the vertical direction. Vibrations of the body of a vehicle with a rigid axle that are caused by the vehicle drive, irregularities in the roadway and unbalance of the wheels are minimized.
