首先根據給定車型的整車參數和技術要求,確 定 制動器的結構形式 、驅動形式及 制動器主要參數,然后計算制動器的制動力矩 、制動效能因數、制動減速度 、制動溫升等,并在此基礎上進行制動器主要零部件的結構設計 ,如制動鼓、制動蹄、制動底板等 。制動系統(tǒng)的主要部件就是制動器,在現代汽車上仍然廣泛使用的是具有較高制動效能的蹄 — 鼓式制動器。 鼓式制動也叫塊式制動 , 現在鼓式制動器的主流是內張式,它的 制動鼓 位于制動輪內側,剎車時制動塊向外張開,摩擦制動 鼓 的內側,達到剎車的目的。最后,完成裝配圖和零件圖的繪制。在設計過程中,以實際產品為基礎,根據我 國工廠目前進行制動器新產品開發(fā)的一般程序,并結合理論設計的要求進行設計。 摘 要 制動系統(tǒng)在汽車中有著極為重要的作用,如果失效將會造成災嚴重的后果。 本設計就摩擦式鼓式制動器進行了相關的設計和計算。 關鍵詞 : 鼓式制動器 ,制動力矩,制動效能因數,制動減速度,制動溫升 ABSTRACT In the vehicle brake system is very important. Braking failure can be result in serious consequences. The main part of the braking system is the brake. In the modern car brake shoe brake drum which has high braking efficiency is still widely used. Drum brake, also known as blocktype brake. The mainstream of drum brakes is sheets style, and its brake shoes located inside the brake wheel. When braking, brakeblocks open outward to friction the inside of the brake drum. The design of the friction drum brakes were related to the design and calculation. The design based on the actual product, accord to our country brake factory general new product development process, and union theoretical design requirements. The first, according to assigns vehicle the parameter and the specification, determine th
