摘要： A lower side bearing for a wheel truck, including: a first friction board, a second friction board, an inner pedestal, a bearing sleeve sleeving the inner pedestal, a pressure block, a pressure plate, and an elastic component. The pressure block is disposed on an upper part of the inner pedestal, and the second friction board is disposed on a top of the pressure block. The pressure plate is disposed on an upper part of the bearing sleeve, and the first friction board is disposed on a top of the pressure plate. A friction coefficient μk of the first friction board and a friction coefficient μz of the second friction board meet the relation: μk>μz. The elastic component is disposed between the inner pedestal and the bearing sleeve for controlling a relative position of the inner pedestal and the bearing sleeve.

摘要： The present invention provides a variable stiffness positioning device for a railway vehicle bogie axle box. The variable stiffness positioning device includes a vertical elastomer arranged between the top face of an axle box bearing saddle and the bottom surface of a guide frame of a side fame, and a longitudinal elastomer arranged between the axle box bearing saddle and the front and back side faces of the guide frame of the side fame, the longitudinal elastomer is provided with at least one small-stiffness elastic element and a large-stiffness elastic element, and the small-stiffness elastic element is arranged in an elastomer pre-compression device and is serially arranged with the large-stiffness elastic element under the action of a pre-compression load F1. The longitudinal elastomer has a larger longitudinal compression stiffness when the longitudinal deformation displacement is very small, so that the railway vehicle can be guaranteed to have a higher snaking critical operation speed when operating on a straight line, and the acceleration operation demand of the vehicle is satisfied; when the longitudinal deformation displacement reaches a set numerical value, the longitudinal compression stiffness of the longitudinal elastomer starts to become small, so that when the railway vehicle passes by a curve, it can be guaranteed that the lateral force between wheel rails will not be too large, and thus the curve operation safety of the vehicle is guaranteed.
