轻型货车设计（离合器及操纵机构与传动轴设计）

摘要

在这三个月的时间里，我的最重要的任务之一就是设计汽车离合器、其操纵机构，以及传动轴的设计。

众所周知汽车底盘包括传动系、行驶系和转向系，传动系部件包括离合器、变速器、传动轴、驱动桥、半轴及驱动轮。在传动系的这些部件中，离合器和变速器无疑是两个最为重要的部件。驾驶员通过操纵离合器既可以在变速器换档时使发动机与离合器暂时分离，也可以在汽车起步时使发动机与离合器平稳接合。离合器的设计采用膜片弹簧压紧机构，液压式操纵机构。在国外，常采用液压操纵机构的离合器以减轻驾驶员的疲劳，

通过对传动轴的传动类型分析，对传动方式和传动轴进行了选型；通过对传动轴的类型与结构分析，选择了传动轴的十字轴滚针轴承的密封形式——盖板式密封。通过对万向节的十字轴、滚针轴承、万向节叉的设计计算，确定了所设计车辆使用的这些部件的具体尺寸。

综合各部分的设计及校核结果，所设计的离合器、传动轴能满足所设计的轻型货车的传动要求。

THE DESING OF A LIGHT TRUCK (THE CLUTCKAND THE MANIPULATION OF INSTITUTIONS AND SHAFT DESIGN)

ABSTRACT

In these two month-long time, one of my most vital duties is designs the

automobile clutch ,Its control mechanism, as well as drive shaft design.

The well known motor car chassis including the power transmission, the travel is and the steering system, the power transmission part including the meeting and parting Transmission gearbox, drive shaft, driving axle, rear axle and driving gear. In power transmission these parts, to Gathering and the transmission gearbox are two most important parts without doubt. The pilot through operates the coupling already to be possible in The transmission gearbox shifts gears when causes the engine and the coupling separates temporarily, also may starts when the automobile cause the engine and Coupling steady joint. The coupling design used the disk spring to contract the organization, hydraulic control organization. In overseas, often uses the hydraulic control organization the coupling by to reduce pilot's weariness.

Through to the drive shaft transmission type analysis, has carried on the shaping to the type of drive and the drive shaft; Through to the drive shaft type and the structure analysis, chose the drive shaft cross axle needle bearing seal form to cover the board style seal. Through to the universal joint cross axle, the needle bearing, the universal joint sliding yoke design calculation, had determined designs these parts concrete sizes which the vehicles uses.

Synthesizes each part of designs and the check result, designs the coupling, the drive shaft can satisfy skin truck which designs to use the transport vehicle the transmission request.

KEY WORDS: Coupling drive shaft cross axle control mechanism
