As shown in FIG. 4, a typical brake band is constructed by crimping brackets 4, 4' to both ends of a curved thin steel strap 3 with an adhesive on the inside, and then bonding a thin wet friction material 2 of paper type to the inside of the curved strap 3, and wrapping the whole around the brake drum 1.
In this way, the brake band is fixed and wrapped around the drum 1 at two points, the fulcrum and the point of application, and when the brake band operates, since there is no guide to restrict it in the circumferential and axial directions, the brackets 4, 4' which are crimped to the strap 3 can move freely, resulting in malfunction due to lateral slippage, etc.
〔問題点を解決するための手段〕
この考案では従来の欠点を解消するために、両

In the brake band of this invention, guides are provided on both brackets to suppress movements other than sliding movement toward each other, so when the brakes are applied, the brackets are prevented from shifting in the lateral direction or in the vertical direction. The brackets slide against each other without any movement, resulting in good operability and friction characteristics.

Figure 1 is a front view of the brake band of this invention.
Fig. 2 is a view taken in the direction of arrow A in Fig. 1, and Fig. 3 is a diagram showing an example of the structure of the bracket, in which 1 is a brake band, 2 is a wet friction material, and 3 is an adhesive with adhesive on the inside. It is a strap made of a curved thin steel plate, and a paper type thin wet friction material 2 is adhered to the inside of the strap.
ストラツプ３の両端に同形又は異形のブラケツ

お図において、符号４２は、ブレーキバンドのプ
ツシユロド取付部を示している。 Brackets 4, 4' of the same or different shape are connected to both ends of the strap 3 by caulking. In the figure, reference numeral 42 indicates a push rod attachment portion of the brake band.
しかして、この考案においては、第１図、第３
図から判るように、ブラケツト４の先端に凸部４
１を形成し、反対側のブラケツト４′には、その
凸部４１を受け入れる案内凹部４１′が形成され
ている。 However, in this invention, Figures 1 and 3
As can be seen from the figure, there is a protrusion 4 at the tip of the bracket 4.
1, and a guide recess 41' for receiving the protrusion 41 is formed in the opposite bracket 4'.
第２図は第１図のＡ方向矢視図であつて、第２
図ａは凸部４１が１個の場合を示し、第２図ｂは
凸部４１がたて方向に２個存在している場合を示
している。 FIG. 2 is a view taken in the direction of arrow A in FIG.
Figure a shows a case where there is one protrusion 41, and Figure 2b shows a case where there are two protrusions 41 in the vertical direction.
この考案のブレーキバンドはこのような構成で
あつて、一方のブラケツト４に設けられた凸部４
１が他方のブラケツト４′に設けられた案内凹部
４１′に入り凹部４１′に案内されて摺動するの
で、ブラケツト４，４′は互に相対向する方向に
のみ摺動し、横方向のずれや、上下方向の動きは
抑止される。 The brake band of this invention has such a structure, and has a convex portion 4 provided on one bracket 4.
1 enters the guide recess 41' provided in the other bracket 4' and slides while being guided by the recess 41', so the brackets 4, 4' slide only in directions facing each other, and do not move in the lateral direction. Misalignment and vertical movement are suppressed.
この考案のブレーキバンドは前記のような構成

The brake band of this invention has the above-mentioned structure, and the guide provided on the bracket prevents lateral displacement and vertical movement, which were the drawbacks of the conventional brake band, so it can be used without sacrificing flexibility. Ideal circumferential operation is possible, improving operability, friction characteristics, etc.
