Braking device

A braking device for a vehicle, comprising a disc of a disc brake suitable for rotating about a rotation axis, wherein said disc comprises a disc body;

• and wherein said disc body comprises a braking band having opposite braking surfaces;
• and
• wherein said disc body comprises at least one connection portion suitable for connecting the disc to a connection device of a vehicle associable with the braking device;
• and wherein said braking band defines an axial direction parallel to the rotation axis of the disc, a radial direction orthogonal to the axial direction and a tangential direction or circumferential direction, orthogonal both to the axial direction and to the radial direction;
• and wherein said at least one connection portion comprises seat walls which delimit at least one seat;
• and wherein said seat walls comprise:
• at least one dragging surface suitable for receiving a thrust action directed in circumferential direction,
• at least one abutment surface opposed to said dragging surface;
• and wherein said braking device further comprises at least one bush, suitable for being connected to a portion of said connection device;
• and wherein said at least one bush comprises at least one engagement portion which is inserted with clearance into said seat, and wherein said braking device comprises at least one elastic element interposed between said abutment surface and said engagement portion of said bush;
• and wherein said at least one elastic element comprises at least one arm, which projects cantilevered into said seat and which comprises a free terminal end and an attachment root, which comprises at least one contact area of said elastic element with said seat walls;
• wherein said at least one arm comprises at least one working portion which touches said engagement portion of said bush and affects said bush to abut against said dragging surface,
• wherein said at least one working portion of said at least one arm affect said at least one bush in said radial direction.
