DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1A and 1B show a first preferred embodiment of a brake disc structure with composite materials according to the present invention. The brake disc structure with composite materials 10a includes an inner disk 11 and at least two outer disks 12a. The inner disk 11 is disc-shaped and made of a light metal material, wherein the light metal material has a specific gravity less than 4 g/cm3 and is a material such as aluminum alloy or titanium alloy. The outer disks 12a are respectively stacked on an upper surface and a lower surface of the inner disk 11 and combined with the upper and lower surfaces of the inner disk 11 through a metallurgical reaction process. The above outer disks 12a are disc-shaped and made of a ferrous metal material, wherein the ferrous metal material is a cast iron material or a stainless steel material. An axle hole 121 is opened in the center of the outer disk 12a for being fitted on a hub and penetrates the inner disk 11, thereby constituting the brake disc structure with composite materials 10a having the properties of abrasion resistance and light weight. The above-mentioned metallurgical reaction process is a rolling method, a lamination method, or a diffusion method.
In addition, the peripheries of the above-mentioned outer disks 12a are respectively provided with a disk brake surface 122. A plurality of stripping holes 123 is opened in the space sandwiched between the disc brake surface 122 and the axle hole 121, and penetrates the inner disk 11. A rib 124 is formed between the adjacent stripping holes 123. Further, a plurality of heat dissipation holes 125 is formed in the disc brake surface 122 of each outer disk 12a, and penetrates the inner disk 11, so as to exhaust the heat produced during the brake rapidly.
FIGS. 2A and 2B show a second preferred embodiment of the brake disc structure with composite materials according to the present invention. The brake disc structure with composite materials 10b includes an inner disk 11 and at least two outer disks 12b. The inner disk 11 is disc-shaped and is made of a light metal material, wherein the light metal material has a specific gravity less than 4 g/cm3 and is a material such as aluminum alloy or titanium alloy. An axle hole 111 is opened in the center of the inner disk 11 for being fitted on a hub, and the outer disks 12b are respectively stacked on an upper surface and a lower surface of the inner disk 11 and respectively combined with the upper and lower surfaces of the inner disk 11 through a metallurgical reaction process. The outer disks 12b are disc-shaped and hollow, and are made of a ferrous metal material, wherein the ferrous metal material is a cast iron material or a stainless steel material, thereby constituting the brake disc structure with composite materials having the properties of abrasion resistance and light weight. The above-mentioned metallurgical reaction process is a rolling method, a lamination method, or a diffusion method.
Moreover, the peripheries of the above-mentioned outer disks 12b are respectively provided with a disk brake surface 122, and a plurality of stripping holes 112 is opened in the inner disk 11 in the space sandwiched between the outer disks 12b and the axle hole 111. A rib 113 is formed between the adjacent stripping holes 112. Further, a plurality of heat dissipation holes 125 is formed in the disc brake surface 122 of each outer disk 12b and penetrates the inner disk 11, so as to exhaust the heat produced during the brake rapidly.
Furthermore, FIGS. 3A and 3B show a third preferred embodiment of the brake disc structure of composite materials according to the present invention. The brake disc structure of composite materials 10c includes an inner disk 11c, at least two outer disks 12b, and a disk fixing member 13. The inner disk 11c is disc-shaped and hollow and made of a light metal material, wherein the light metal material has a specific gravity less than 4 g/cm3 and is a material such as aluminum alloy or titanium alloy. The outer disks 12b are respectively stacked on an upper surface and a lower surface of the inner disk 11c and respectively combined with the upper and lower surfaces of the inner disk 11c through a metallurgical reaction process. The outer disks 12b are disc-shaped and hollow, and are made of a ferrous metal material, wherein the ferrous metal material is a cast iron material or a stainless steel material. The above disk fixing member 13 is engaged with the inner disk 11c through bolting. An axle hole 131 is opened in the center of the disk fixing member 13 for being fitted on a hub, and the disk fixing member 13 is made of a light metal material or a ferrous metal material, wherein the light metal material such as an aluminum alloy or a titanium alloy has a specific gravity less than 4 g/cm3, and the ferrous metal material is a cast iron material or a stainless steel material, thereby constituting the brake disc structure with composite materials 10c having the properties of abrasion resistance and light weight. The above-mentioned metallurgical reaction process is a rolling method, a lamination method, or a diffusion method.
In addition, the above-mentioned outer disks 12b are respectively provided with a disk brake surface 122. A plurality of stripping holes 132 is opened in the disc fixing member 13 in the space sandwiched between the axis hole 131 of the disk fixing member 13 and the inner disk 11c. A rib 133 is formed between adjacent stripping holes 132. Besides, a plurality of heat dissipation holes 125 is formed in the disc brake surface 122 of the outer disks 12b and penetrates the inner disk 11c, so as to exhaust the heat produced during the brake rapidly.
Referring to FIG. 4, when the brake disc structure with composite materials 10a is used together with a brake main body 20 and locked to a fork 30 of a vehicle to form a brake device, the brake main body 20 is used to grip the brake disc, so as to slow down or stop the vehicle. Likewise, the brake disc structures with composite materials 10b and 10c of the present invention are also used to slow down or stop a vehicle, and the brake disc structures with composite materials 10a, 10b, and 10c of the present invention are also adapted for a brake disc of a bicycle.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
