制动器

制动器(中文6000字,英文3000字)
制动器：它们的作用？
简单的说：它会使你的汽车慢下来。
复杂的说：制动器被用来让你的车减速，但可能不是你所想的意思。普遍的误解是，制动器挤压制动鼓或制动片，挤压的压力的作用使你的车慢下来。但这只是制动的一部分。制动系统本质上是改变能量的类型。当你在全速行驶时，你的汽车获得动能。这是热力学第一定律，有时被视为能量守恒定律。也是就说：能量不能被创造也不能被消灭，只能由一种形式转换成另一种。制动情况下，它是动能转化为热能。
角向力。 因为在盘式制动器的刹车片和转子的位置，摩擦产生的接触点的位置也产生了一个机械的抵御转子的回转运动。
THE BRAKE BIBLE
Brakes - what do they do?
The simple answer: they slow you down.
The complex answer: brakes are designed to slow down your vehicle but probably not by the means that you think. The common misconception is that brakes squeeze against a drum or disc, and the pressure of the squeezing action is what slows you down. This in fact is only part of the equation. Brakes are essentially a mechanism to change energy types. When you're travelling at speed, your vehicle has kineticenergy. When you apply the brakes, the pads or shoes that press against the brake drum or rotor convert that energy into thermal energy via friction. The cooling of the brakes dissipates the heat and the vehicle slows down. It's the First Law of Thermodynamics, sometimes known as the law of conservation of energy. This states that energy cannot be created nor destroyed, it can only be converted from one form to another. In the case of brakes, it is converted from kinetic energy to thermal energy.
