The present invention relates to an assembled axle brake disc with a hub and two friction rings which are arranged parallel to and spaced apart from one another.
Assembled axle brake discs are used in particular for rail vehicles, and due to the built form of the axle brake discs, these can be assembled from several individual components.
An assembled axle brake disc is understood as being primarily an axle brake disc that is assembled from at least two components. In particular, an assembled axle brake disc is intended to describe a brake disc that comprises two friction rings that are not formed as a single piece and that share a uniform structure, for example as is known in a casting method, but which are provided individually and which are preferably assembled using further elements to form a friction ring pair using joining techniques. As a further individual part, the hub can be joined in an assembly with the friction ring pair.
Further measures that improve the invention will be presented in greater detail below together with the description of preferred exemplary embodiments of the invention with reference to the figures, in which:
FIG. 1 shows an exemplary embodiment of an axle brake disc in a perspective view with the features of the present invention
FIG. 2 shows a cross-section through an axle brake disc with an insert element and friction rings arranged on this
The same reference numerals from different exemplary embodiments refer to the same functional parts, with slightly different features.
FIG. 1 shows in a perspective view an exemplary embodiment of an axle brake disc 100 according to the invention, and the axle brake disc 100 is compiled from several individual parts, so that the axle brake disc 100 is designed as an assembled axle brake disc 100.
The axle brake disc 100 comprises a hub 10, and in the hub 10 a central passage is created, through which a shaft can extend on which the axle brake disc 100 is arranged. Further, the axle brake disc 100 comprises friction rings 11 and 12, which are arranged parallel to and spaced apart from one another, and which form the friction surfaces for contact with brake pads.
