本考案は車両用ブレーキ装置のベンチレーテツ
ドデイスクに関するものであり、自動車、産業用
車両等に利用される。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ventilated disk for a vehicle brake system, and is used in automobiles, industrial vehicles, and the like.

ている（例えば、特公昭48−3781号公報）。(Prior Art) Conventionally, in a ventilated disk, an inner disk and an outer disk are connected by a large number of ribs extending in the radial direction, and a ventilation hole is provided between the two disks and the ribs. The inner opening area of the pore is smaller than the outer opening area (for example, Japanese Patent Publication No. 48-3781).
（考案が解決しようとする課題）
デイスクを任意の一方向に回転すると通気孔内
の空気は遠心力によつて外側開口から押し出さ
れ、通気孔内の気圧が減少し新しい空気を内側開
口より吸い込み、デイスクの裏面に送風して冷却
しているが、内側開口面積が外側開口面積より小
さく形成されているので、送風能力が低く思うよ
うな冷却効果が期待できないという問題点があ
る。(Problem to be solved by the invention) When the disk is rotated in one arbitrary direction, the air in the vent is pushed out from the outer opening by centrifugal force, the air pressure inside the vent decreases, and new air is sucked in from the inner opening. Although air is blown to the back surface of the disk to cool it, there is a problem in that the inner opening area is smaller than the outer opening area, so the cooling effect cannot be expected due to the low air blowing capacity.
そこで、本考案はかかる問題点を解消するため
になされたもので、通気孔内に従来に比してさら
に流量大なる空気を送風することによつて、より
効率の良い冷却効果を有するデイスクを提供する
ものである。 Therefore, the present invention was devised to solve this problem, and by blowing a larger amount of air into the ventilation holes than before, it is possible to create a disk with a more efficient cooling effect. This is what we provide.

ツドデイスクである。(Means for solving the problem) The present invention forms the outer end of the first rib extending in the radial direction into a bifurcated shape, and interposes the second rib in the shape of a flat plate extending in the radial direction between the first ribs. Furthermore, it is a ventilated disk in which the width of the sliding surface of the inner disk is narrower than the width of the sliding surface of the outer disk.

びアウターデイスクが冷却される。(Function) Since the present invention has the above-mentioned configuration, when the inner opening area is larger than the outer opening area, or is formed to be slightly larger, and the disk is rotated in any one direction, a new flow rate larger than that of the inner opening is generated. Air is drawn in and forced into the vents, cooling the inner disk and the outer disk, inter alia via the first rib and the second rib.

The inner disk 3 and the outer disk 4 are connected by the ribs 1, 1 and the second ribs 2, 2, and the outer ends of the first ribs 1, 1 are formed into a bifurcated shape, and the second ribs 2, 2 is formed from an aluminum flat plate. Further, the width of the sliding surface 5 of the inner disk 3 is formed narrower than the width of the sliding surface 6 of the outer disk 4, and both the disks 3, 4
A ventilation hole 7,
A large number of ventilation holes 7 are provided, and the area of the inner openings 8 of the ventilation holes 7, 7 is larger than or slightly larger than the area of the outer openings 9. 10 is a cylindrical hat portion integrally connected to the outer disk 4.

イスク４が冷却される。 When the ventilated disk is rotated in one arbitrary direction, the air in the vents 7, 7 is pushed out from the outer openings 9, 9 by centrifugal force, the air pressure in the vents 7, 7 decreases, and new air is forced inside. A large amount of air is sucked in through the openings 8, 8 and forced into the ventilation holes 7, 7, and especially the first ribs 1, 1 and the second ribs 2,
The inner disk 3 and the outer disk 4 are cooled through the inner disk 2.
