    • A cable operated drum brake has an internal brake operating lever (12) provided with an quick-attach device (10) for an operating cable (11). A cable attachment tube (21) projects from a backplate (17) of the brake and the operating cable has a cable inner (13) with a latching formation (14) on the end thereof and a cable outer sleeve (15). An end portion of the operating cable is slideable towards (X) the backplate (17) within the tube (21) up to a first position at which further movement towards the backplate is stopped by contact between an abutment (26) on the tube and a cooperating abutment (31a) on the cable outer sleeve. When in the first position the latching formation (14) has moved passed the quick-attach device (10). The cable is then subsequently moveable away from the backplate (Y) within the tube to a second position in which the latching formation (14) on the cable inner is fully engaged with the quick-attach device (10). A fastening means (39,40) is provided to lock the cable in the second position relative to the tube to maintain the latching formation (14) engaged with the quick-attach device (10) during subsequent operation of the brake. The invention also provides a method of attaching an operating cable to a quick-attach device on an internal brake operating lever of a drum brake.
    • 电缆操作的鼓式制动器具有内部制动操作杆(12),其设有用于操作电缆(11)的快速附接装置(10)。 电缆连接管(21)从制动器的背板(17)突出,并且操作电缆具有在其端部上具有闩锁结构(14)的电缆内部(13)和电缆外套筒(15)。 操作电缆的端部可以朝向管(21)内的背板(17)的方向(X)滑动到第一位置,在第一位置处,通过管上的邻接(26)和管 电缆外套上的协作基座(31a)。 当处于第一位置时,锁定结构(14)已经移动通过快速附接装置(10)。 然后电缆随后可以从管子内的背板(Y)移动到第二位置,在第二位置,电缆内部上的闩锁结构(14)与快速附接装置(10)完全接合。 提供紧固装置(39,40)以相对于管子将电缆锁定在第二位置,以在随后的制动器操作期间保持闩锁结构(14)与快速附接装置(10)接合。 本发明还提供了一种将操作电缆附接到鼓式制动器的内部制动操作杆上的快速连接装置的方法。
