Friction ring 1 comprises two relative annular elements 11, and each annular element 11 all has external peripheral surface 6, outer braking surface 7 and internal surface 8.The internal surface 8 of two described annular elements 11 is oppositely arranged and interconnects by multiple radiating fin 2, each radiating fin 2 centered by hub 3 to external radiation.
With reference to Fig. 2 and Fig. 3, the non-braking surface of brake disc at least comprises the internal surface 8 of described annular element 11, external peripheral surface 6.The internal surface 8 of the annular element of described brake disc, external peripheral surface 6 and the radiating fin surface 4 of radiating fin 2 described at least one, thrin or its any both and above combination have temperature indicating coating, in the process that described temperature indicating coating changes from low to high in the temperature on the radiating fin surface 4 of internal surface 8, external peripheral surface 6 and the described radiating fin 2 of described annular element 11, while arriving each preset temperature, show successively the corresponding color that each are different, color generation irreversible change.
Foregoing, temperature indicating coating can only be positioned on the internal surface 8 of annular element or on external peripheral surface 6, also can only be positioned on radiating fin surface 4, also can be positioned on any both combination of three simultaneously, can certainly be positioned on three simultaneously.
The advantage that temperature indicating coating is positioned on described internal surface 8 is that temperature detection is more accurate, because nearer apart from the rubbing surface of friction ring; Temperature indicating coating is located at the change in color that the advantage on radiating fin surface 4 is it and is more easily observed.
In one embodiment, preferably, the radiating fin surface 4 of described multiple radiating fin 2 has temperature indicating coating, in the process that described temperature indicating coating changes from low to high in the temperature on radiating fin surface 4, shows successively the corresponding color that each are different while arriving each preset temperature.
In the time being positioned on radiating fin surface 4, temperature indicating coating can apply the periphery in friction ring 1, is preferably in the radiating fin 2 that outermost makes a circle, and the change in color of temperature indicating coating is easily observed like this, also relatively saves cost simultaneously.Certainly, temperature indicating coating also can be coated in the radiating fin 2 of the inner side in friction ring 1.
Easily expect, temperature indicating coating can be coated with covered with the whole radiating fin surface 4 in radiating fin 2; Also can only apply local radiating fin surface 4, preferably part radiating fin surface 4 outwardly, so that observe and cost-saving.
Certainly, coated portion or whole temperature indicating coatings on the internal surface 8 of annular element or on external peripheral surface 6, be also desirable.
Above-mentioned various coating schemes are all feasible, and in actual use, under brake disc entrucking state, whether inspection personnel can look after radiating fin surface 4 with suitable light such as torch has corresponding look to become, and judges the maximum temperature that brake disc stands.
Temperature indicating coating can manual application, also can spray, or adopt other suitable mode to apply, and it can not affect enforcement of the present invention.
In the present invention, the concrete structure of brake disc can have multiple variation, and especially the fastening piece 5 between hub 3 and disk body can be substituted by other linkage structures.For example, linkage structure can be a bell flange, the central axis of bell flange is identical with the central axis of hub 3, bell flange has the inside being connected with hub 3, inside and outside radial part described in the outside and connection being connected with friction ring 1, this inside forms the bell top of bell flange, and this outside forms the bell shirt rim of bell flange, and this radial part forms the bell side of bell flange.Bell flange is preferably shaped on hub 3 and friction ring 1, and outside is connected to radiating fin 2.Such structure can prevent that hub 3 is pulled radially outward expansion in braking.
And for example, linkage structure can also be made up of radial elastic link, radial elastic link comprises connecting bolt, nut, square key, pressure ring, resilient key and key, pad, resilient key is contained in hub 3, connecting bolt is contained in resilient key, and friction ring 1 is contained on resilient key, successively square key, pressure ring is contained on resilient key, key is contained between hub 3 and pressure ring, and bolt is contained on nut by pad.What such structure made that friction ring 1 can move radially is connected in hub 3, and friction ring 1 can be along radially free shrink of hub 3 in the time that braking is heated, and is difficult for producing hot crack.
Except the above-mentioned variation to linkage structure, the form that specifically arranges and Placement that those skilled in the art can understand hub 3, friction ring 1 and radiating fin 2 all can have numerous embodiments, and it can not affect realization of the present invention.
