摩擦离合器按压紧力产生的方式可分为:电磁的、液压的和机械的三种。不论是片式的(图la),还是锥式的(图1b),都需要采用一定的结合机构来产生轴向压紧力,使摩擦离合器传递所需要的扭矩。对结合机构的要求是: 1.传力比(压紧力与结合力之比)要大,即力经过操纵机构和结合机构传递后 Friction clutch pressure generated by the way can be divided into: electromagnetic, hydraulic and mechanical three. Both lamellar (Figure la), or cone (Figure 1b), need to use a certain combination of mechanisms to produce axial compression force, the friction clutch to deliver the required torque. The requirements of the binding mechanism are: 1. Force transmission ratio (compression and binding force ratio) to be large, that force through the steering mechanism and the binding mechanism after delivery
