Definitions
- the disc for a disc brake according to the present invention finds application particularly, but not exclusively, in the automotive industry, especially on heavy motor vehicles, such as for example SUVs or large-sized MPVs .
- the discs for a disc brake comprise a bell from which a ring portion, referred to as a braking band, extends, which is intended to cooperate with pads of a caliper.
- the braking band is made of two plates, which are mutually facing e connected together by connecting elements, for example, in the form of pins or wings.
- the external surfaces of the two plates define opposite braking surfaces, while the internal surfaces define, together with the pins or wings, ventilation ducts to cool the disc, which are passed through by the air according to a centrifugal direction during the rotational motion of the same disc.
- the brake discs and in particular the braking bands, generate annoying noises and whistles, which may also- be very intense.
- This phenomenon occurs when the braking band is excited at frequencies that are near or equal to the intrinsic vibration modes.
- the known resonance phenomenon occurs when a body is excited in the vicinity of the intrinsic vibration modes. If the frequency of such vibration falls within the range of frequencies audible to a human being, such vibrations generate annoying whistles, which are audible within the vehicle interior, to the detriment of the comfort and the perceived quality of the vehicle.
- a brake disc of the ventilated type with such a braking band as to increase the rigidity of the structure, thereby increasing the frequencies of the diametrical vibration modes of the braking band.
- the two plates of the braking band are interconnected by radial wings.
- the structure is diametrically stiffened by thickening the outermost radial end of one out of two wings by means of a drop-shaped mass that is arranged at the connecting area of the wing itself with one of the two plates.
- projections suitable to equilibrate the weight of the drop-shaped stiffening masses are arranged.
- Such projections are arranged at the outlet of the ventilation ducts that are not affected by the stiffening masses, so as not to create ventilation ducts with an excessively reduced opening.
- the described solution allows only partially increasing the frequencies of the intrinsic diametrical vibration modes of the disc. Therefore, the reduction of the resonance phenomenon in the range of the audible frequencies is limited.
- a brake disc of the ventilated type is disclosed, which is provided with inserts of a material having vibration dampening capabilities, arranged on the internal surfaces of both plates.
- the inserts are arranged at the ventilation ducts within special grooves, and radially extend substantially throughout the length of the ducts.
- the solution is not particularly efficient, and it is anyway constructively complex to be manufactured, and therefore it is not cost- effective .
- a brake disc of the ventilated type is disclosed, which is provided with vibration dampening elements that are removably inserted into one or more ventilation ducts.
- dampening elements are elastic bodies made of an elastic cable, which is suitably shaped to contact both plates.
