環状に銅ロー付けした構造のブレーキデイスクを
用いていた。 In vehicles such as motorcycles where the brake disc is exposed to the outside, stainless steel is used as the material for at least the friction surface of the brake disc to prevent rust from forming on the friction surface. In addition, due to the demands for lighter brake discs, increased rigidity, and heat dissipation, conventionally the base disc was made of medium- to high-carbon steel with good hardenability or carbon-rich alloy steel, and martensitic stainless steel was used instead of martensitic stainless steel. The brake disc used a structure in which a friction plate made of steel was brazed with copper in an annular shape.

析出したクロムは基円盤中の炭素と結合し、ここ
に炭化クロム層を形成する。 However, when a steel material with a large amount of carbon (base disc) and stainless steel containing chromium (friction plate) are brazed with copper, the chromium in the stainless steel dissolves into the copper solder due to a diffusion phenomenon, causing the chromium to melt. Precipitates on the surface of the base disk. Since this chromium has the property of easily bonding with carbon, the chromium deposited on the surface of this base disk combines with the carbon in the base disk to form a chromium carbide layer there.
この炭化クロム層は非常に脆い性質を持つため
ブレーキデイスクに大きな機械的、熱的衝撃が加

下するという問題があつた。 This chromium carbide layer is extremely brittle, so if a large mechanical or thermal shock is applied to the brake disc, cracks may occur in the chromium carbide layer, reducing the mechanical strength of the brake disc. It was hot.
本発明はこのような事情に鑑みなされたもの

In the figure, reference numeral 10 is a front fork.
This fork 10 is attached to a head pipe 14 of a frame 12 so as to be swingable from side to side, and a front wheel 16 is attached to its lower end. A brake disc 18 is fixed to the hub of the front wheel 16, and a caliper 20 for clamping the brake disc 18 is attached to the front fork 10. By operating a brake lever (not shown) provided on the right grip of the steering handle 22,
Brake pads (not shown) within the caliper 20 squeeze the brake disc to generate braking force. In this figure, 24 is the front and rear V-type water-cooled engine, 26 is the radiator, 28 is the rear wheel, 30 is the fuel tank, and 32
is a sheet.

側面には、予めニツケルメツキが施されている。 The brake disc 18 includes a base disk 34 and friction plates 36, 36a, and 36b, as shown in FIGS. 2-4. The base disc 34 is made of medium/high carbon steel, alloy steel containing a large amount of carbon, etc., and has a large number of notches 38 on its outer periphery and is formed into a substantially comb shape. The left and right side surfaces of this comb-shaped portion of the base disk 34 are pre-plated with nickel plating.

冷却性を高めることができる。 The friction plate 36 is made of stainless steel and has an annular shape, and is brazed with copper to the comb-shaped portion of the base disk 34. For example, this friction plate 36 is copper-brazed by compressing and heating a copper foil of a predetermined thickness interposed between it and the base disc 34. Furthermore, this friction plate 36
The width in the radial direction is smaller than the depth of the notch 38 in the base disk 34, and as shown in FIGS. Open on the side. Therefore, when the disk 18 rotates, air flows radially outward within the notch 38, thereby improving the cooling performance of the disk 18.

強固な結合を得ることができる。 The structure of the copper brazed portion of the disk 18 made in this way is shown in FIG. That is, a nickel plating layer 40 is formed on the side surface of the base disk 34, and the friction plate 36 is fixed via a copper layer 42 for brazing. Stainless steel friction plate 36
The chromium contained in the copper layer 42 diffuses into the copper layer 42 and dissolves out, and is deposited on the surface of the nickel plating layer 40 to form a chromium layer 44. On the other hand, since carbon contained in the base disk 34 is prevented from diffusing by the nickel layer 40, it does not combine with chromium and a brittle chromium carbide layer is not formed. Also, Nickel has a base disk of 3
4 and into the copper layer 42 and form an alloy, a strong bond can be obtained.

Although it is preferable from the point of view of cost reduction, the entire base disk 34 may be covered. Further, it goes without saying that the friction plate 36 may be formed by cutting out crescent-shaped members and arranging them in an annular shape on the base disc 34 for convenience of material removal when cutting out the stainless steel plate.

化により軽量化も可能になる。 As described above, in the present invention, a base disk containing carbon is plated with nickel, and a ring-shaped friction plate made of stainless steel is brazed with copper to the nickel plated portion. Therefore, the chromium in the friction plate does not combine with the carbon in the base disk, and a brittle chromium carbide layer is not formed. Therefore, the strength of the brake disc can be improved. Furthermore, since the base disc has good hardenability, by hardening the base disc, it is possible to improve the rigidity of the brake disc, and on the other hand, it is also possible to reduce the weight by making the base disc thinner.
