The invention concerns a railway vehicle wheel with elastic rubber suspensio n designed in particular, but not exclusively, for low railway vehicles. In sa id railway vehicle, the wheel tyre (2) is connected to the wheel rim (3) via a rubber lining consisting of two flat rings (11, 12) substantially vertical relative to the wheel shaft. The rings (11, 12) are highly preloaded axially between an inner circumferential median rib (5) of the wheel tyre and two outer flanges (6, 8) of the rim (3). At least one of the flanges (8) is supported on the rim (3) by an adjusted seat (9) in a conical tight fit. The adjusted seat (9) is configured such that the cone of the flange (8) when fr ee of tension has a tapering smaller than that of the cone of the rim (3) and when compressed, presses its entire surface on the cone of the rim (3) with a compressive surface as uniform as possible over the entire width of the adjusted seat (9). The flange (8) is thus securely maintained. Additional threaded screws (10) are therefor not necessary in the zone of the rings (11 , 12) of the rubber lining, such that the space found between the rib (5) and the flanges (6, 8) can be exclusively used for the rubber lining.
