た。(Problem to be solved by the invention) In the conventional brakes as described above, the disc generates frictional vibrations and makes a whining noise when braking.
The phenomenon of brake whistling often occurred. In addition, because the disk portion a1 is made thicker, it is difficult to manufacture it from a plate material, and a casting process and a cutting process are required, making it impossible to produce it efficiently.
したがつて、嗚音が発生し難く、かつ加工も容
易なデイスクを得ることが望まれていた。 Therefore, it has been desired to obtain a disk that is less likely to generate whistling noise and is easy to process.

ことを特徴とする。(Means for Solving the Problems) The present invention solves the above-mentioned problems, and its means include providing friction surfaces on both sides of an annular disk portion and protruding a hub connecting portion on the inner circumferential surface. In the disc brake disc, two friction plates, a friction plate having a hub connection part and a ring-shaped friction plate, are laminated by brazing the entire surface with soft metal solder, and pin holes are provided in the hub connection part and the hub, The present invention is characterized in that a pin with radial play is inserted into the pin hole, and the hub connecting portion and the hub are elastically connected by the head of the pin and the washer.

音量も低下する。(Function) Since the above-mentioned means is provided, the two hard friction plates are joined by a relatively soft metal solder, so the solder layer has a damping effect on the vibrations of the friction plates, reducing the whining noise. is less likely to occur. Further, the vibration of the friction plate is attenuated by the friction at the connecting portion where the disk portion and the hub portion are in elastic contact, thereby reducing the sound volume.
また、摩擦板が２枚用いられるだけであるか
ら、デイスク部が薄く形成されてブレーキが小型
になる。 Furthermore, since only two friction plates are used, the disk portion can be formed thinner and the brake can be made smaller.

2, which passes through the pin holes 9, 11 and the elastic washer 13 and is fixed with a caulking part 14. The elastic deformation of the washer 13 allows relative movement in the radial and axle directions, and the disk portion 2 forms a floating disk that can follow the pad and tilt with respect to the hub 3.

However, the pin 4 is made into a tapered stepped pin, and the pin hole 9 is fixed to the disk portion 2 so that the pin hole 9 has an inner diameter that tightly fits into this tapered portion.
A clearance may be provided between the large diameter portion of the pin 4 and the pin hole 11 so that the pin 4 can freely move only in this portion.

いから製造も簡単である。 In the present invention, as described above, the friction plates 5 and 6 are joined by metal solder, so that vibrations are absorbed and attenuated by the solder layer during braking, and the generation of whistling noise is reduced.
Furthermore, since the hub connecting portion 8 is pressed against and frictionally engaged with the washer 13 and the hub 3 by the elasticity of the washer 13, etc., part of the vibration of the friction plate 5 is absorbed by the friction of these contact surfaces. This also reduces whining. In addition, the friction plates 5 and 6 can be made by simply punching out plate materials, and the brazing process is simple, as it is only necessary to interpose a brazing material between the friction plates and heat and cool them in a furnace. be.

がある。(Effects of the invention) As described above, this invention absorbs vibrations by the solder layer between the two friction plates laminated together, and also absorbs vibrations by the friction at the connecting part between the disk part and the hub. This has the effect of making it difficult to generate whistling noise, and since it can be made by punching and brazing plates, it is suitable for mass production, and moreover, it only uses two friction plates, which is the minimum number of layers. Because of this, the thickness of the disc is small, which makes it possible to make the brake compact and improve the ease of mounting it on a vehicle, as well as to reduce costs.
