<p>A braking device (1), unusually capable of low operating vibration and of compensation of thermal deformations, comprises: a brake disc (2) having an axial - symmetrical body (3), said body (3) comprising a brake band (4), said body (3) comprising at least two connection portions (7) of the brake disc (2); said brake band (4) comprising at least two radial seats (10) that each define a dragging surface (13), arranged in the axial direction; said radial seat (10) also defines an opposite abutment surface (14) substantially parallel to said dragging surface (13); said disc device also comprises at least two bushings (15); each of said bushings (15) comprising at least one portion (18) that is inserted in said radial seat (10); said braking device (1) also comprises elastic means (19) arranged between the radial seat (10) and said bushing (15); - said elastic means (19) exerting an elastic action in the tangential direction (C-C) between the bushing (15) and the radial seat (10); said elastic means (19) being anchored to the radical seat (10) and creating a predeterminated resistance action suitable for controlling the axial movement (A-A) of the break disc (2) with respect to the bushing (15).</p> |
