  "abstract": "Described is a brake disc, rotating about its own axis of rotation, including a brake strip, an element for supporting the brake strip and a plurality of first elements for connecting the brake strip with the supporting element which can be elastically deformed in such a way as to allow a relative movement of the brake strip with respect to the supporting element. The supporting element includes at least a first component and a second component connected to the brake strip by means of the first connecting elements. A plurality of second connecting elements of the first component and of the second component are elastically deformable in such a way as to allow a relative movement between the first component and the second component.",

  "description_excerpt": "This application claims priority to Italian Patent Application 102020000006805 filed Apr. 1, 2020, the entirety of which is incorporated by reference herein.\n\nThis invention relates to a brake disc.\n\nMore specifically, the brake disc according to this invention is preferably for use by bicycles or motorcycles with two or more wheels, without thereby limiting the scope of the invention.\n\nAs is known from the prior art, the brake strip of a brake disc is subjected to a high level of heating during braking and is particularly sensitive to thermal expansion due to its thickness, which is to be considered reduced in relation to the considerable extension of its surface.\n\nThis heating may induce deformations of the brake strip both in the diametric direction and in the axial direction of the disc, creating considerable problems in the mechanics of the braking.\n\nTo overcome these problems, which are especially evident in the systems of motorcycles with high-performance and for sports use, use is made of the so-called “floating” and “semi-floating” brake discs which usually consist of an internal support, an external brake strip and an elastic system for attaching the support with the brake strip which allows a relative movement, or misalignment, of the brake strip with respect to the support in the diametric direction or in the axial direction or in both directions.",
