Abstract
The invention relates to a slider (1) for track vehicles which allows for horizontal relative movements in the longitudinal as well as in the latitudinal direction between the superstructure, such as a freight car body or another vehicle body, and the running gear or between running gear parts. The invention has the task of retaining the effect of the friction in a slider of the described kind in one horizontal direction while eliminating it in the other direction. This problem is solved by mounting the slider on coupling elements, which allow for a nearly unrestricted sliding of the slider within a certain range in one of the two horizontal directions (longitudinally or latitudinally) and which fix the slider rigidly in the other one of the two horizontal directions. The coupling elements are rolling bearings or friction bearings arranged between the slider and the spring or they comprise an upper and a bottom metal cover plate with a middle rubber layer which includes vertically arranged sheet metal strips running parallel and spaced apart and in a straight line.
