The invention relates to an improved expansion device (1) for a drum brake (4) having an integrated readjustment device (8) having a readjusting screw (9) therein that can be blocked by means of a spring-biased latching unit (12) which, for a reliable readjustment function, provides for the latching unit (9) to permit a defined idle rotation (L) of the readjusting screw (9), which is defined constructionally by a first stop (13) acting in a first direction of revolution and a second stop (14) acting in the opposite direction of revolution.

    本发明涉及一种用于鼓式制动器(4)的改进的张开装置(1),其包括具有其中可借助于弹簧加载的卡锁装置(12)锁止的微调螺钉(9)的集成的微调装置(8),为了在减小的力水平时可靠的微调功能,张开装置设置成,卡锁装置(12)实现微调螺钉(9)的规定的空转行程(L),通过在第一环绕方向上作用的第一止挡部(13)和在相反的环绕方向上作用的第二止挡部(14)在结构上确定空转行程。
