摘要： A foot-operated parking brake lever assembly wherein a double-manual operation is required to effect release of the parking brake. The assembly is provided with a pawl having a first pawl section and a second pawl section. The first pawl section is pivotally mounted on a brake lever which is in turn pivotally mounted on a stationary support formed with a series of ratchet teeth. The first pawl section is formed with a finger for selectively engaging the ratchet teeth and thereby retaining the brake lever in brake setting positions thereof. The second pawl section is mounted on the first pawl section for limited rotational movement therewith. The second pawl section is urged by pawl biasing means in a direction to cause the finger of the first pawl section to engage the ratchet teeth when the second pawl section is in a rotational position subject to the limiting action by limiting means and in a direction to cause the ratchet teeth of the first pawl section to be disengaged from the ratchet teeth when the second pawl section is in a rotational position free from the limiting action by the limiting means. Brake lever biasing means urges the finger of the first pawl section in a direction to engage the ratchet teeth.
摘要翻译：一种脚踏式驻车制动杆组件，其中需要双手动操作来实现驻车制动器的释放。组件设置有具有第一棘爪部分和第二棘爪部分的棘爪。第一棘爪部分枢转地安装在制动杆上，该制动杆又可枢转地安装在形成有一系列棘轮齿的固定支撑件上。第一棘爪部分形成有用于选择性地接合棘齿的手指，从而将制动杆保持在其制动设置位置。第二棘爪部分安装在第一棘爪部分上，用于与其有限的旋转运动。第二棘爪部分被棘爪偏压装置沿着使第一棘爪部分的手指接合棘轮齿的方向被推动，当第二棘爪部分处于受限制装置的限制作用的旋转位置时，当第二棘爪部分处于不受限制装置的限制作用的旋转位置时，使第一棘爪部分的棘齿脱离棘齿。制动杆偏压装置沿着与棘齿啮合的方向推动第一棘爪部分的手指。
