1、蘭州工業(yè)高等?？茖W(xué)校畢業(yè)論文摘要汽車后橋是汽車的主要部件之一，其基本的功用是增大由傳動軸或直接由變速器傳來的轉(zhuǎn)矩，再將轉(zhuǎn)矩分配給左右驅(qū)動車輪，并使左右驅(qū)動車輪具有汽車行駛運(yùn)動所要求的差速功能:同時(shí)，驅(qū)動橋還要承受作用于路面和車架或承載車身之間的鉛垂力、縱向力，橫向力及其力矩。其質(zhì)量，性能的好壞直接影響整車的安全性，經(jīng)濟(jì)性、舒適性、可靠性。本文認(rèn)真地分析參考了江淮HF15015卡車驅(qū)動橋以及韓國現(xiàn)代468號驅(qū)動橋，在論述汽車驅(qū)動橋運(yùn)行機(jī)理的基礎(chǔ)上，提練出了在驅(qū)動橋設(shè)計(jì)中應(yīng)掌握的滿足汽車行駛的平順性和通過性、降噪技術(shù)的應(yīng)用及零件的標(biāo)準(zhǔn)化、部件的通用化
