【発明の詳細な説明】
この発明は自動車、自動二輪車などのブレーキ装置にお
ける制動子に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brake element in a brake device for automobiles, motorcycles, etc.
制動子の具体的な形状はブレーキ装置の形式によって異
なるけれども、基本的には摩擦材からなるライニングを
ブレーキシューに貼り付けた構造であって、摩擦材とし

ている。Although the specific shape of the brake element varies depending on the type of brake device, it basically has a structure in which a lining made of friction material is attached to the brake shoe, and the friction material is asbestos with about 30% copper powder. Conventionally, synthetic resins that are mixed to improve heat dissipation and molded into the desired shape have been commonly used.
このような石綿系の摩擦材料は相手部材であるティスフ

りライニングが濡れた場合には績擦特性の低下が著しく
、ときには制動効果が殆ど半減する。捩言すれば皺測状
態での制動には乾燥状態の約２倍の力Ｊｆ−要すること
がある。Such asbestos-based friction materials have excellent properties such as being less likely to damage the mating parts such as tires and drums, and less reducing the coefficient of friction due to noise generation or heat generation during operation. On the other hand, if water enters the brake device and the lining becomes wet, the friction characteristics are significantly reduced, and in some cases, the braking effect is almost halved. In other words, braking in a wrinkled state may require approximately twice as much force Jf as in a dry state.
乾曽時と＃Ｉｊ潤時とでブレーキの効き具合にこのよう
な大差があることは、とっさの場合に事故の斐因となる
大きな欠点である。The fact that there is such a large difference in the effectiveness of the brakes when it is dry and when it is wet is a major drawback that can cause an accident in the event of an accident.
そこで本発明は、石綿系＊振材の上述の長所を残し、か

方向に沿って交互に配設したことにある。Therefore, the present invention provides a damper J that retains the above-mentioned advantages of asbestos-based vibration material and has no significant difference in braking effect between dry and wet conditions.
The gist of this is that asbestos-based friction members and sintered alloy friction members having the above composition are alternately arranged along the sliding direction of the lining.

and FIG. 2 both show the implementation of the present invention.
Along the sliding direction from the top left to the bottom right of the figure,
Asbestos-based friction materials 2 and sintered alloy friction members 3 are alternately arranged on a brake shoe 1.

This figure shows a comparison of the lII friction characteristics of the sintered alloys (dotted lines) made by five West German companies.The friction coefficient of the sintered alloys according to the present invention is almost the same as that of conventional materials.
耐摩耗性が著しく改善されていることがわかる。It can be seen that the wear resistance is significantly improved.

とができる。Preliminary tests have shown that the sintered alloy of the present invention requires greater braking force in dry conditions than asbestos-based friction materials, but unlike asbestos-based friction materials, it has a higher braking force when wet than when dry. It also has the characteristic of having a high braking effect. Therefore, by arranging both members alternately along the sliding direction of the lining, it is possible to obtain a brake f that takes advantage of the advantages of each member.

This greatly helps improve safety.
