Bearing device for wheel axles

Bearing device for wheel set axle shafts having enclosed in an axle bearing housing a wheel bearing comprising an inner ring fitted on the axle and an outer ring aligned with and around the inner ring with roller means between the said rings, and with the inner ring held securely in place by securing means, said device including energy storage means between the wheel bearing and the axle bearing housing in order to accommodate forces acting on the wheel bearing in the operating position, wherein the outer ring running around the inner ring is in the form of a middle or intermediate ring, a second ring resting on said middle ring braced via said energy storage means against the axle bearing housing such that both said middle ring and said second ring can be moved with respect to each other over a limited range thus permitting a certain degree of tilt between the axle and the axle bearing housing.

Device according to calim 7 including a securing ring and counterlying ring positioning said middle ring therebetween, such that there is a ring-shaped opening between counterlying ring and said housing and another such opening between the sidewall ring and the securing ring, and membranes bridging over both said openings.
