摘要： In a clearance compensator a rod (12) is fixed to one of the shoes of the brake and is slidable in an intermediate element (13) threadedly engaged in another rod (11) secured to the other shoe. A heat-sensitive bi-metal strip (18) projects from a leaf spring (14) operable to urge the rod (12) away from the intermediate element (13). The bi-metal strip (18) is orientated substantially tangentially of a ratchet wheel (17) fixed to the intermediate element (13); at its free end, the bi-metal strip (18) has a stop element (18a) for engaging the ratchet wheel (17). At temperatures above a predetermined value, the strip (18) assumes a heat-induced deflected condition in which the stop element (18a) is disengaged from the wheel (17).

摘要： An electrically operated drum brake (10) has a brake shoe (11, 12) displaceable into contact with an associated rotatable brake drum by an electrical actuator (14) in the form of a screwing jack to apply the brake. The shoe reacts against a support abutment (13a) carrying a load sensing means (40) which actions discontinuance of operation of the electrical actuator in a brake disengaging sense when the load applied to the support abutment by the shoe falls to a predetermined level.

摘要翻译： 在间隙补偿器中，杆（12）固定在制动器的一个制动蹄上，并且可以在中间元件（13）中滑动，中间元件（13）与另一个固定在另一个制动蹄上的杆（11）螺纹啮合。 热敏双金属带（18）从可操作以推动杆（12）离开中间元件（13）的板簧（14）突出。 双金属带（18）基本上与固定在中间元件（13）上的棘轮（17）相切地取向; 在其自由端处，双金属带（18）具有用于接合棘轮（17）的止动元件（18a）。 在高于预定值的温度下，条带（18）呈现热致偏转状态，在该状态中止挡元件（18a）从轮子（17）脱离。
