本案は自動二輪車等の車両の車輪に装備される
ドラムブレーキの浸水防止装置に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a water immersion prevention device for drum brakes installed on the wheels of vehicles such as motorcycles.
ドラムブレーキの浸水防止装置は、一般に第３
図に示すように、ドラムブレーキ機構１を収容し

As shown in the figure, a labyrinth groove 4 is formed in several stages on the opposing peripheral portion between a wheel hub 2 housing a drum brake mechanism 1 and a brake panel 3 arranged on the end face of the wheel hub 2. Further, a labyrinth groove 4 is formed on the outer peripheral edge of the brake panel 3.
A flange 31 is provided to cover the edge of the
本案は上記ドラムブレーキの浸水防止を更に確

状のシールゴム６をはめる。 That is, as shown in FIG.
A groove 5 parallel to the labyrinth groove 4 is formed in the groove 5, and a ring-shaped seal rubber 6 is fitted therein to close the gap between the hub 2 and the brake panel 3.
そしてブレーキパネル３の最下部において、上
記シールリング嵌合溝５を第２図５１に示すよう
に平に欠除し、シールリング６をその欠除部５１
に沿わせることにより、シールリング６の一部６
１とハブ２の内周面との間に小隙ｇを形成する。 Then, at the lowest part of the brake panel 3, the seal ring fitting groove 5 is cut out flatly as shown in FIG.
By aligning the part 6 of the seal ring 6 with
A small gap g is formed between the hub 1 and the inner circumferential surface of the hub 2.
上記シールリング６は、図のようにラビリンス
溝４よりも内側に設けるを可とする。シールリン

５２を設ける。ハブ内周面のシールリング６が摺
接する部分に鋼板等の耐摩耗部材を張ることもあ
る。 The seal ring 6 can be provided inside the labyrinth groove 4 as shown in the figure. In order to prevent the seal ring fitting groove cutout 51 from directly opening outward, a hanging wall 52 is provided at the outer end of the cutout 51. A wear-resistant member such as a steel plate may be applied to the portion of the inner peripheral surface of the hub where the seal ring 6 makes sliding contact.
本案ドラムブレーキ浸水防止装置は、上記の構
成であるから、ラビリンス溝４とシールリング６
の併用によつてドラムブレーキ１に対する浸水を
略確実に防止することができる。シールリング６
はラビリンス溝４と平行の溝５にはめ込まれてい
るので、位置がずれることはない。 Since the drum brake flood prevention device of the present invention has the above configuration, the labyrinth groove 4 and the seal ring 6
By using these in combination, it is possible to almost reliably prevent water from entering the drum brake 1. Seal ring 6
Since it is fitted into the groove 5 parallel to the labyrinth groove 4, the position will not shift.
そしてハブ２とブレーキパネル３のすき間はシ
ールリング６によつてふさがれるものの、最下部
においてはハブ内周面との間に小隙ｇがあるため
ライニング摩耗粉は容易にその小隙ｇから排出さ
れる。その小隙ｇから水が入ることもあるが、下
部であるから直ぐ排水される。 Although the gap between the hub 2 and the brake panel 3 is closed by the seal ring 6, there is a small gap g between the inner peripheral surface of the hub and the inner peripheral surface of the hub at the bottom, so lining wear powder can be easily discharged from the small gap g. be done. Water may enter through the small gap g, but since it is at the bottom, it drains immediately.
又上記シールリング６による浸水防止効果の向
上により、ラビリンス溝４を従来のものに比べて
単純化することができ、カバーフランジ３１（第
３図）も不要となるので、ブレーキ装置全体の加
工を容易にすると共に、軽量になる効果がある。 In addition, due to the improved water intrusion prevention effect provided by the seal ring 6, the labyrinth groove 4 can be simplified compared to the conventional one, and the cover flange 31 (Fig. 3) is also unnecessary, so that machining of the entire brake device can be simplified. This has the effect of making it easier and lighter.
更に上記ライニング摩耗粉排除用小隙ｇを形成
するシールリング嵌合溝欠除部５１の外端開口の
前に垂壁５２が位置しているので、小隙ｇに外か
ら異物が侵入するのを防ぐ効果がある。 Furthermore, since the hanging wall 52 is located in front of the outer end opening of the seal ring fitting groove cutout 51 that forms the small gap g for removing lining wear powder, foreign matter is prevented from entering the small gap g from the outside. It has the effect of preventing
