【考案の詳細な説明】
本考案は自動三輪車等における外付け密封式の
ドラムブレーキに関する。[Detailed Description of the Invention] The present invention relates to an external sealed drum brake for motor tricycles and the like.
自動三輪車は四輪車と異なり、ドラムブレーキ
を各後輪のハブに組込むのではなく、第１図に示
すように、後車輪よりも内側において車軸上に設
置したいわゆる外付け密封式ドラムブレーキが用
いられる。そして車軸とブレーキカバーとの間に
ダストシールを設ける。 Unlike four-wheeled vehicles, tricycles do not have drum brakes built into the hub of each rear wheel, but instead use so-called external sealed drum brakes installed on the axle inside the rear wheels, as shown in Figure 1. used. A dust seal is then provided between the axle and the brake cover.
ところがこの種の車両は、オフロード車として
山野・海岸等を走行することが多いため、ダスト
シールの所からドラムブレーキの中に塵埃・泥水
等が侵入することを極力防止することが望まれ
る。 However, since this type of vehicle is often driven as an off-road vehicle in mountains, fields, coasts, etc., it is desirable to prevent dust, muddy water, etc. from entering the drum brake from the dust seal as much as possible.

シール部６を設けたことを要旨とする。 This invention was proposed in view of the above points,
In a drum brake in which a brake cover 2 is hermetically attached to a brake panel 1, the brake drum 3 is fixed to a tube shaft 4 by welding or the like, and the tube shaft 4 is spline-coupled to an axle 5, and the spline joint portion 21 is The tube shaft 4 is located near the fixed portion 22 of the brake drum 3 and the tube shaft 4, and extends further toward the brake cover 2 from the spline joint 21 with the axle 5. The gist is that a gap 23 is formed between the inner circumferential surface and the axle 5, and a seal portion 6 is provided between the outer circumferential surface of the extension portion 4A and the brake cover 2.
ブレーキパネル１は従来のものと同様に車軸外
管７に溶接し、その周縁部にブレーキカバー２の
周縁部をパツキン８を挟んで重ね合せ、ボルト・

を構成する。 The brake panel 1 is welded to the axle outer tube 7 in the same manner as the conventional one, and the peripheral edge of the brake cover 2 is overlapped with the outer circumferential edge of the axle tube 7 with the gasket 8 in between, and the bolts and
A sealed case is constructed by joining with nuts 9 and 10.

3 is a brake arm mounting shaft; 14 is a nut screwed onto a threaded portion of the axle 5 for fixing the tube shaft 4 supporting the brake drum 3; 15 is a washer; and 16 is a breather.
本考案は密封式のドラムブレーキを上記の構成
にしたから、走行に伴つて車軸５に振れを生じて

ちブレーキカバー２側において、管軸４の延長部
４Ａと車軸５の間に形成された空隙２３が車軸５
の振れを吸収する。 In the present invention, since the sealed drum brake is constructed as described above, even if the axle 5 shakes during running, the axle 5 of the tube shaft 4 to which the brake drum 3 is fixed
A gap 23 formed between the extension portion 4A of the tube shaft 4 and the axle 5 is formed on the outside of the spline connection point for the axle 5, that is, on the brake cover 2 side.
Absorbs vibrations.
従つて空隙２３の外周に位置しているブレーキ
カバー２と管軸延長部４Ａとの間のシール部６に
対する車軸５の振れによるねじれ作用の影響が少
なくて、長期にわたつてシール性を維持すること
ができてブレーキ内への泥水・塵埃等の侵入を可
及的に防止できる。 Therefore, the influence of twisting action due to vibration of the axle 5 on the seal portion 6 between the brake cover 2 and the tube shaft extension portion 4A located on the outer periphery of the gap 23 is reduced, and sealing performance is maintained over a long period of time. This makes it possible to prevent muddy water, dust, etc. from entering the brake as much as possible.

でブレーキ面の掃除ができる。 A hole 17 is provided at the upper front of the brake cover 2, into which a cap 18 with a knob made of an elastic material such as rubber or plastic that engages in an eyelet shape is removably fitted, and a drain with a stopper 19 is fitted. When the hole 20 is provided at the bottom of the brake panel 3, a hose is inserted into the hole 17 and water or air is blown into the hole 17.
By discharging the fluid through the hole 20, the interior of the brake case can be easily cleaned without disassembling the brake case. Furthermore, if a hole 3a is made in the brake drum 3, it will communicate with the hole 17 and the brake surface can be inspected, or a hose can be inserted into the hole 17, 3a to clean the brake surface.
