...Anti-skid brakes are said to have first been used on the American strategic bomber Boeing B-47 in 1947, but more recently, microcomputer-based, high-performance brakes have begun to be used on passenger cars. Special friction brakes include the screw brakes used to prevent loads from dropping when lifting equipment such as chain blocks are released, and the centrifugal brakes that start working at high rotation speeds. Incidentally, the engine brake that operates when a car is moving and the driver takes his or her foot off the accelerator without disengaging the clutch can be considered a friction brake that utilizes the compression resistance of the engine and the mechanical friction of the engine and transmission. ... *Some of the terminology that refers to "centrifugal brakes" is listed below.

…アンチスキッドブレーキは1947年にアメリカの戦略爆撃機ボーイングB47に用いられたのが最初とされているが,最近ではマイコンを用いた性能の優れたものが乗用車に使われ始めている。 摩擦ブレーキの特殊なものとしては,チェーンブロックなどのつり上げ機で手をゆるめたときに荷が下がらないようにするために用いるねじブレーキ,回転数が高くなると効き始める遠心ブレーキなどがある。なお,自動車の走行中,クラッチを切らずにアクセルから足を離したときに作用するエンジンブレーキは,エンジンの圧縮抵抗,エンジン・変速機の機械摩擦を利用した摩擦ブレーキとみなすことができる。… ※「遠心ブレーキ」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
