求翻译：这种制动器的制动盘的全部工作面积可同时与摩擦片接触。全盘式制动器主要用于重型汽车。全盘式制动器摩擦副的固定元件和旋转元件都是圆盘形的，分别称为固定盘和旋转盘，其工作原理与摩擦离合器相似。是什么意思？

This brake disc brake work area can be in contact with the friction plate. Overall brake for heavy vehicles. Fixed components and rotating components of the overall brake friction pair of disc-shaped, are called fixed disk and a rotating disk, its working principle is similar to the friction clutch.

This brake disc can be all of the work area with both disks. Overall, mainly used for heavy duty truck brakes. Overall brake friction and the rotation of the fixed element is a disc-shaped element of the disc, known as the fixed and rotating disk, it works similar to friction clutch.

This kind of brake brake disc completely working area may simultaneously with the friction disk contact.The entire disc brake mainly uses in the heavy automobile.The entire disc brake rubs the vice-fixed part and the revolving part all is disc-shaped, is called the fixed tray and the rotating disc s

This brake brake disc of all of your work area for both contact with friction. Overall brake mainly for heavy trucks. Fixed components of the overall brake friction pair and rotating components are disc-shaped, are called the fixed and rotating disks, it works similar to a friction clutch.
