文档介绍：重型自卸汽车设计(离合器设计)
离合器装在发动机与变速器之间,汽车从启动到行驶的整个过程中,经常需要使用离合器。它的作用是使发动机与变速器之间逐渐接合,从而保证汽车平稳起步;暂时切断发动机与变速器之间的联系,以便于换档和减少换挡时的冲击;当汽车紧急制动时能起分离作用,防止变速器等传动系统过载,起到一定的保护作用。离合器类似开关,接合或断离动力传递作用,因此,任何形式的汽车都有离合装置,只是形式不同而已。其结构是否合理,性能是否与整车匹配,直接关系到汽车的操纵性、动力性及经济性。本说明书主要研究离合器与整车的匹配性设计,具体内容做了以下几个方面:
根据设计的要求完成了汽车的总体设计,并且对汽车的结构型式和主要参数进行了选择。
对离合器的结构方案进行了分析对比,选择离合器形式。
根据前面的汽车总体设计,对离合器基本尺寸、参数进行了选择。
对离合器零部件进行选型、匹配性设计和校核计算。
对离合器操纵系统的设计。通过对机械式操纵系统和液压式操纵系统特点的分析,并选取了液压式操纵系统,对其进行了设计和尺寸计算。

dump truck Clutch Design
The coupling installs between the engine and the transmission gearbox, the automobile from the start to the travel entire process, needs to use the coupling frequently. Its function is causes between the engine and the transmission gearbox can join gradually, thus guaranteed that the automobile starts steadily; shuts off between the engine and transmission gearbox's relation temporarily, is advantageous shifts gears and reduces shifts gears the time impact; When automobile emergency brake can play the separation role, prevents transmission systems and so on transmission gearbox to overload, plays certain protective function. Therefore, any form's automobile has the engaging and disengaging gear, is only the from is different. The structure of the clutch is reasonable or not, whether the performance matching to the total vehicle, is directly related to the automotive ease of use, vehicle dynamics and the economics and the economy. This paper studies the clutch and matching to the vehicle design.
Specific content of the following aspects of the paper on the following main areas of research:
According to the design requirements of the automobile plete the total design, and chose the structure type and the structure type and the main parameters of the vehicle.
Compared to the structure of the Clutch, and chose the construction form of the clutch.
Under the previous car design, made a choice to the basic clutch size parameters.
Made right clutch parts for the clu
