本発明は、車両用デイスクブレーキに使用する
フローテイング型のブレーキデイスクに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floating brake disc used in a vehicle disc brake.

が一般的であつた。(Prior art) Floating type brake discs, as seen in Utility Model Application No. 60-3333, consist of a braking part and a hub separately and are connected so that both parts can move minutely. Distortion is prevented from occurring in the braking surface due to frictional heat, and the means for connecting the two parts has generally been to use pins inserted into opposing recesses provided in both parts.

あつた。(Problems to be Solved by the Invention) In the above-mentioned prior art, a pin with a head is used as the pin that connects the brake part and the hub, and a disc spring and a washer are caulked to the tip of the pin. To fix it to the axle, a bolt integrated with the axle was passed through the hub's mounting hole and a nut was screwed on. Since the head of this pin or the disc spring and the nut are arranged on the side of the hub, they must be placed apart from each other so that they do not interfere with each other, but in small brakes, it is not possible to place them apart. A difficult situation arose.

This means includes a brake disk in which a hub is connected to the inner periphery of a ring-shaped brake part so as to be able to move minutely, and a bottomed receiving hole extending in the axle direction extending between the brake part and the hub, and the receiving hole. A steel ball housed in
The present invention is characterized in that a plurality of connecting parts each having a caulked part in which the opening of the receiving hole is caulked inward is provided.

Since the connecting portion is formed in a small size, there is sufficient space for screwing the nut for fixing the axle.
（実施例）
以下図面によつて本発明の実施例を説明する。
第１図ないし第４図において１は本発明のブレー
キデイスクで、制動部２とハブ３を連結部４で連
結している。(Example) Examples of the present invention will be described below with reference to the drawings.
In FIGS. 1 to 4, reference numeral 1 designates a brake disk of the present invention, which connects a braking portion 2 and a hub 3 through a connecting portion 4. As shown in FIG.
制動部２とハブ３はリング状をなし、制動部２
には摩擦面５に多数の冷却用の通気穴６が穿設し
てあり、内周部７は、僅かの間隙をもつてボス部
３の外周部８に嵌合しており、ハブ２には車軸穴
９、取付穴１０、意匠上の穴１１等が設けてあ
る。 The brake part 2 and the hub 3 are ring-shaped, and the brake part 2
A large number of cooling ventilation holes 6 are bored in the friction surface 5 of the hub 2, and the inner circumferential portion 7 fits into the outer circumferential portion 8 of the boss portion 3 with a slight gap. is provided with an axle hole 9, a mounting hole 10, a design hole 11, etc.
連結部４には、第５図に示すように前記内周部
７と外周部８にまたがる車軸方向の有底の受穴１
２が穿設され、したがつて両部７又は８には受穴
半部１２ａ，１２ｂ底部１３ａ，１３ｂが形成さ

交互に穿設するのが好ましい。 As shown in FIG. 5, the connecting portion 4 has a receiving hole 1 with a bottom in the axle direction extending between the inner circumferential portion 7 and the outer circumferential portion 8.
2 are drilled, so that both portions 7 or 8 are formed with receiving hole half portions 12a, 12b and bottom portions 13a, 13b. Preferably, the receiving holes 12 are formed alternately from both the front and back surfaces of the disk.
受穴１２に第６図に示すように鋼球１４を収容

１４の間には僅かの隙間があり、制動部２とハブ
３は、半径方向及び軸方向に微小の相対移動がで
きる。 As shown in FIG. 6, the steel ball 14 is accommodated in the receiving hole 12, and the opening is caulked inward to form the caulked portion 15a,
When the steel ball 15b is formed, the steel ball is sealed and held in the receiving hole 12, connects the braking part 2 and the hub 3, and transmits braking torque. There is a slight gap between each of the receiving hole halves 12a, 12b and the steel ball 14, so that the brake part 2 and the hub 3 can move minutely relative to each other in the radial and axial directions.
ボス部３の取付穴１０を車軸と一体のボルトに
嵌合して仮想線で示すナツト１６を螺着すること
によりブレーキデイスク１は車軸に固定される
が、連結部４には鋼球１３の頂部が僅かに露出す
るだけであるから、取付穴１０と連結部４の距離
が小さくても、ナツト１６と鋼球露出部分との間
には距離ｌが残り相互に干渉することがない。 The brake disc 1 is fixed to the axle by fitting the bolt integrated with the axle into the mounting hole 10 of the boss part 3 and screwing the nut 16 shown in phantom lines. Since the top portion is only slightly exposed, even if the distance between the mounting hole 10 and the connecting portion 4 is small, a distance l remains between the nut 16 and the exposed portion of the steel ball, so that they do not interfere with each other.

軽量化に有益である。(Effects of the Invention) As described above, the connecting portion of the present invention can be made compact, so even in a small brake disc that requires the nut and the connecting portion to be placed close to each other to be attached to the axle, the nut and the connecting portion can be made small. parts can be easily arranged without mutual interference.
Further, the drilling of receiving holes, caulking, etc. are simple processes, and only inexpensive steel balls are used as parts, so the brake disc can be manufactured inexpensively and efficiently. Furthermore, since the connecting part is simple, it is easy to install a large number of these to reduce the load per piece, making it possible to downsize the connecting part, which allows the use of thin plates for the braking part and the boss part. This is useful for reducing the size and weight of the brake.
