    • In a disk brake actuated preferably hydraulically, a piston (5) is guided within a housing located in a caliper. When pressure is applied, the piston acts in such a manner against a brake shoe (15) bearing a brake lining (17) that the brake shoe (15) is pressed with its brake lining against the brake disk to be braked. The side of the piston facing the brake shoe has a pressure plate (13) which transmits the pressure forces and which moves transversely within its recess in the piston (5). The pressure plate (13) is mounted on the end of a tappet (25) extending axially inside the piston (5) and bracing itself at the end opposite the pressure plate by a disk (27) at the bottom (29) of the bore (31) accommodating the tappet, and is surrounded by a prestressed compression spring (37). Lateral movements of the pressure plate (13) cause tipping of the tappet (25) and, as a consequence thereof, a reset force exerted by the compression spring (37 ) on the tappet (25) and, thus, on the pressure plate (13). This reset force can be precisely defined by use of a threaded ring (39) whose position can be changed and which braces one end of the compression spring (37).
    • 在优选液压地驱动的盘式制动器中,活塞(5)在位于卡尺内的壳体内被引导。 当施加压力时,活塞以这种方式抵靠着制动衬片(17)的制动瓦(15),制动衬片(17)的制动衬片(15)被制动衬片压在制动盘上以被制动。 面对制动蹄的活塞的侧面具有压力板(13),该压力传递压力并且在活塞(5)内的凹部内横向移动。 压板(13)安装在轴向在活塞(5)内部延伸的挺杆(25)的端部上,并且在与压力板相对的端部处由在孔的底部(29)处的盘(27)支撑自身 (31),其容纳所述挺杆,并且被预应力的压缩弹簧(37)包围。 压板(13)的横向运动导致挺杆(25)的倾斜,并因此导致由压缩弹簧(37)施加在挺杆(25)上并因此施加在压板(25)上的复位力 13)。 可以通过使用其位置可以改变并且支撑压缩弹簧(37)的一端的螺纹环(39)来精确地限定该复位力。
