摘要： A drum brake includes a wheel cylinder which cooperates with a pair of brake shoes to urge the latter to a braking position. In order to attach the wheel cylinder to a backing plate, a flange is disposed in abutment with the backplate and the wheel cylinder and a nut cooperates with the flange and the wheel cylinder to prevent separation between the wheel cylinder and the backing plate. Moreover, the nut and flange include openings for receiving a fitting communicating with the wheel cylinder. The nut extends through the flange opening to engage the wheel cylinder and the nut opening is dimensioned to receive the fitting in spaced relation thereto.

摘要： A drum brake is disclosed in which a pair of arcuate brake shoes are slidably mounted on a fixed support and which are thrust into braking engagement with a rotating drum by a fluid motor actuator. Resilient hold-down springs are provided to attach the brake shoes to the drum and consist of an anchor portion which is engaged with the fixed support and a linking portion which interconnects the anchor portion and the brake shoe. A detent is provided on the web of the brake shoe in a position such that, when the brake shoe is installed on the fixed support with the detent projecting away from the fixed support, the linking portion of the hold-down spring will engage the detent and cannot be connected to the anchor portion. In this way, the shoes must be installed correctly with the projections facing towards the fixed support in order to connect the portions of the hold-down springs, thereby preventing incorrect assembly of the brake.
摘要翻译： 公开了一种鼓式制动器，其中一对弓形制动蹄可滑动地安装在固定的支撑件上，并且通过流体马达致动器被推动与旋转的滚轮制动接合。 提供弹性的压紧弹簧以将制动蹄附接到滚筒，并且包括与固定支撑件接合的锚定部分和将锚定部分与制动蹄相互连接的连接部分。 在制动瓦的腹板上设置有一个制动爪，其位置使得当制动蹄安装在固定的支撑件上时，制动爪突出远离固定支架，止动弹簧的连接部分将与制动器接合 并且不能连接到锚定部分。 以这种方式，鞋子必须正确地安装，其中突起面朝向固定支撑件，以便连接压紧弹簧的部分，从而防止制动器的错误组装。

摘要： A brake lining wear sensor produces an audible signal when it engages a rotating brake drum upon a predetermined amount of lining wear. The sensor is disposed within a groove between a friction lining and a brake shoe rim. Portions of the sensor project away from a body portion and engage the rotating brake drum to produce the warning signal. The projecting portions also cooperate with surfaces of the brake shoe rim or the friction lining to retain the sensor within the groove.
摘要翻译： 当制动衬片磨损传感器在预定量的衬里磨损时与制动鼓接合时产生可听见的信号。 传感器设置在摩擦衬里和制动蹄边之间的凹槽内。 传感器的一部分远离主体部分伸出并接合旋转的制动鼓以产生警告信号。 突出部分还与制动靴边缘或摩擦衬片的表面配合以将传感器保持在凹槽内。
