Disclosed is a railway wagon bogie vibration damping device capable of providing a composite vibration damping force. The vibration damping device is composed of a wide-body inclined wedge vibration damping part mounted on an upper plane (12) of the bottom of an inclined wedge groove at an end part of a swing bolster (21), and a spring vibration damping part mounted on a lower plane (13) of the bottom of the inclined wedge groove at the end part of the swing bolster, wherein the inclined wedge vibration damping part is connected to the spring vibration damping part via a guide seat (3). A contact friction area of an inclined wedge (1) is large. A lower vibration damping spring (4) is additionally arranged between the inclined wedge (1) and a side frame, so that the frictional resistance where a vehicle is fully loaded is increased. An upper vibration damping spring (2) and the lower vibration damping spring (4) are used in different vertical spaces. The vibration damping device has a simple and compact structure, is easy to manufacture, mount, maintain and repair, realizes the characteristic of a "stable" vibration damping performance in no-load and full-load conditions, also realizes the characteristics of an improved bogie rhombus deformation "control" capability and an improved snake motion stability, and plays an important role in improving the technical performance and operation quality of a railway wagon three-piece bogie, thereby reducing the abrasion of parts of the vehicle and reducing vehicle manufacturing, application and maintenance costs.
