    • This dual mode drum brake provides less stroke loss during the brake operation; a stable parking brake effectiveness; and a comfortable feeling for the operator during the brake operation. A wheel cylinder actuator (15) is positioned between ends (lid) and (12d) of first and second brake shoes (11), (12) ; an anchor block (16) is positioned between the other ends (lie) and (12e); a shoe clearance adjustment device (18) is extended adjacent to the wheel cylinder actuator (15); a parking brake actuator (23) is extended adjacent to the anchor block (16); a bent portion (22c), formed on one side (22b) of a pivot lever (22) pivotally supported on the first brake shoe (11), is inserted between the first brake shoe (11) and the shoe clearance adjustment device (18) while the other side (22d) of the pivot lever (22) functionally engages with the parking brake actuator (23).
    • 这种双模式鼓式制动器在制动操作期间提供较少的行程损失; 稳定的停车制动功能; 并且在制动操作期间对操作者的舒适感觉。 轮缸致动器(15)位于第一和第二制动蹄(11),(12)的端部(盖)和(12d)之间。 锚块(16)位于另一端(11a)和(12e)之间; 鞋间隙调节装置(18)相邻于轮缸致动器(15)延伸; 驻车制动器致动器(23)相邻于所述锚块(16)延伸; 在第一制动蹄片(11)和蹄间隙调节装置(18)之间插入形成在枢轴支撑在第一制动蹄片(11)上的枢转杆(22)的一侧(22b)上的弯曲部分(22c) ),而枢转杆(22)的另一侧(22d)与驻车制动器致动器(23)功能性地接合。
