离合器总成结构图解离合器的种类和工作原理一.离合器的功用和工作原理离合器的功用离合器安装在发动机与变速器之间，用来分离或接合前后两者之间动力联系。
其功用为:(1)使汽车平稳起步。
(2)中断给传动系的动力，配合换档。
(3)防止传动系过载。
离合器的工作原理离合器的主动部分和从动部分借接触面间的摩擦作用，或是用液体作为传动介质(液力偶合器)，或是用磁力传动(电磁离合器)来传递转矩，使两者之间可以暂时分离，又可逐渐接合，在传动过程中又允许两部分相互转动。
目前在汽车上广泛采用的是用弹簧压紧的摩擦离合器(简称为摩擦离合器)。
发动机发出的转矩，通过飞轮及压盘与从动盘接触面的摩擦作用，传给从动盘。
当驾驶员踩下离合器踏板时，通过机件的传递，使膜片弹簧大端带动压盘后移，此时从动部分与主动部分分离。
摩擦离合器应能满足以下基本要求:(1)保证能传递发动机发出的最大转矩，并且还有一定的传递转矩余力。
(2)能作到分离时，彻底分离，接合时柔和，并具有良好的散热能力。
(3)从动部分的转动惯量尽量小一些。
这样，在分离离合器换档时，与变速器输入轴相连部分的转速就比较容易变化，从而减轻齿轮间冲击。
(4)具有缓和转动方向冲击，衰减该方向振动的能力，且噪音小。
including incentives) to ensure the achievement of the quality objectives. According to the company's quality system documents, combined with the specific circumstances of the project, preparation of project quality manual, procedures and work related to the project implementation rules to improve the quality management system of the project. A management review meeting held each year, on the implementation of the quality policy, objectives and review of the problems and propose corrective measures. Efforts and resources necessary for optimal allocation of project construction management (personnel, finance, facilities, information, etc). 3.2 with customer focus project staff establish a "customer-focused" thinking, fully aware that meet their customers ' needs and expectations is the fundamental pursuit of production and services projects. Projects in production and service processes, to: 3.2.1 identify and determine the needs and expectations of the project legal person, interests as the interests of the customer, with customer satisfaction as satisfied, good faith and cooperation, win-win and development; 3.2.2 needs and expectations of the project legal person into production and service management or technical requirements, and allocation of appropriate resources; 3.2.3 meet legal requirements and strive to exceed their expectations. 3.2.4 customers on the quality of projects put into operation for standards, in accordance with the national standard of quality works. 3.2.5 regulations and standards requires the State and issued by the Ministry of the project related tothe current version of the technical specifications, procedures, design institutes and(5)压盘压力和摩擦片的摩擦系数变化小，工作稳定。
