摘 要
輕型汽車在商用汽車生產中占有很大的比重，而且驅動橋在整車中十分重要。它的性能的好壞直接影響整車性能，而對于載貨汽車顯得尤為重要。設計出結構簡單、工作可靠、造價低廉的驅動橋，能大大降低整車生產的總成本。
本文首先確定主要部件的結構型式和主要設計參數，在分析驅動橋各部分結構形式、發(fā)展過程及其以往形式的優(yōu)缺點的基礎上，確定了總體設計方案，采用傳統(tǒng)設計方法對驅動橋各部件主減速器、差速器、半軸、橋殼進行設計計算并完成校核。最后運用AUTOCAD完成裝配圖和主要零件圖的繪制。
關鍵詞：驅動橋；主減速器；差速器；半軸；橋殼
Abstract
Pickup trucks take a large proportion of commercial vehicles production, and the drive axle is one of the most important structure. Drive axle is the one of automobile four important assemblies, its performance directly influence on the entire automobile, especially for the truck .Because using the big power engine with the big driving torque satisfied the need of high speed, heavy-loaded, exploiting the high driven efficiency single reduction final drive axle is becoming the trucks’ developing tendency.
In this paper, first of all determine the structure of major components and the main design parameters, determined on the basis of the design program, using the traditional design method of various parts of the drive axle Main reducer, differential, axle, axle housing was designed to calculate and complete the check. Finally complete the final assembly drawing by using AUTOCAD and mapping the main components.
