汽车专业英语第四章 刹车系统 PPT课件

汽车专业英语第四章 刹车系统 PPT课件
由于暴露于空气中，盘式制动器的散热效果比鼓式 好。这意味着盘式制动器能持续使用更长的时间， 也就是说其抗热衰退性（因受热导致制动效能下降） 要好得多。

➢ Simplex drum brakes：单一的 ➢ Duo-duplex drum brakes: 双 双重 ➢ Duo-servo drum brakes： 伺副 増力
In case of hydraulic braking force actuation, the brakes are applied by means of floating pressure pistons whose travel is not fixed, and which develop tensioning forces which are equal in both directions. One of the two shoes is the leading shoe, i.e. the frictional forces between the brake lining and the brake drum act to support the application force, whereas the frictional forces in the case of the trailing shoe act to oppose the tensioning force.
汽车从原地起步(静止)加速到某一速度需要能量，储存在汽 车中的那部分能量称为动能。要降低车速,制动器必须把动能 转换为热能；转换的速度决定了汽车减速的快慢。
A braking system consists of energy-supplying device, a control device, a transmission device and the brake.
