摘　　要：摩擦式离合制动装置在现代机械中广泛应用。这类装置的工作特点是要求驱动装置输出力大,以传递尽量大的扭转矩和功率,而其工作需要的位移却很小。文章提出了运用压电陶瓷作驱动器的离合制动装置这一技术方案,对它的特点和应用进行了理论分析与研究。结果表明,压电陶瓷离合制动装置具有动作速度快、输出转矩大、驱动功率小、体积小和重量轻的特点,是大扭矩输出的离合制动装置的理想方案。与电磁驱动方式一样,它极易实现自动化。Frictionclutches and friction-brakes have been widely applied on the modern machines. The characteristics of these devices are the larger actuating force but little displacement. In this paper,a new scheme of using the piezoelectric ceramic actuators as clutches and brakes is proposed. The properties and applications of this kind of device have been researched theoretically. The conclusion is that the piezoelectric ceramic clutches and brakes are larger in torque,quick in movement,small in acting power,little in size and weight,and easy in automatization.
