介绍了两种采用正交增力机构的离心式离合器──铰杆增力离心式离合器和斜楔增力离心式离合器，说明了其工作原理，给出输出力和输出转矩、接合角速度和接合转速、额定角速度和额定转速、弹簧最大工作载荷的计算公式，并比较其技术性能。正交增力离心式离合器结构紧凑，制造成本较普通离心式离合器增加甚微，但输出转矩的能力显著提高。 Two types of centrifugal clutches with orthogonal force-increasing mechanism, namely the thrust increasing centrifugal clutches and the wedge thrust increasing centrifugal clutches, are introduced. The principle of the centrifugal clutches is introduced, and the output and output torques, the joint angular velocities and Joint speed, rated angular velocity and rated speed, spring maximum working load of the formula, and compare its technical performance. Orthogonal torque centrifugal clutches, compact structure, manufacturing costs than ordinary centrifugal clutch with little increase, but the ability to output torque increased significantly.
