- 汽車鼓式制動器的設計摘要 汽車是現代交通工具中用得最多,最普遍,也是最方便的交通運輸工具。汽車制動系是汽車底盤上的一個重要系統,它是制約汽車運動的裝置。而制動器又是制動系中直接作用制約汽車運動的一個關健裝置,是汽車上最重要的安全件。汽車的制動性能直接影響汽車的行駛安全性。隨著公路業的迅速發展和車流密度的日益增大,人們對Abstract
The car is most used in modern traffic tools, the most common, and most convenient transport. Automobile brake system is an automobile chassis is an important system, it is to restrict the automobile movement device. While the brake is a brake system directly restricts car motion of a key device, safe driving is the main parts. Automotive braking performance directly affects the vehicle's driving safety. With the rapid development of highway industry and traffic density increasing, people on the safety, reliability of increasingly high demand, in order to ensure the safety of persons and vehicles, must be equipped cars with very reliable braking system. The design for the brake system design. Through access to relevant information, the use of professional theories and professional knowledge of drum brake parts, design calculation and structure design. To meet the following requirements : have sufficient braking efficiency to ensure the vehicle safety; at the same time, in the choice of materials used as harmless to the human body materials.
Keywords: brake, drum brake, braking forc
