摩擦离合器是应用得最广也是历史最久的一类离合器,它基本上是由主动部分、从动部分、压紧机构和操纵机构四部分组点成。主、从动部分和压紧机构是保证离合器处于接合状态并能传动动力的基本结构,而离合器的操纵机构主要是使离合器分离的装置。
离合器的摩擦力和制动器的摩擦力起一样的作用,不同的是压在地面上的重压力变成了离合器中弹簧压在离合器盘上的压力。
The friction force in the clutch works just like the blocks in the frication section of brake, except that the spring presses on the clutch plate instead of weight pressing the block into the ground.
随着压力的减小,离合器工作状态下的摩擦力消失,动力被切断。
With the pressure released, there is no friction at work in the clutch, and the power flow is therefore interrupted.
现有工程机械通常采用接触摩擦片式离合器,这种装置的传递扭矩难以实现无级连续调节。
In construction machinery and equipment, contacting friction disk clutches are mostly used, by which the torque transferred cannot be adjusted easily and continually.
