1、I載重汽車轉(zhuǎn)向梯形的結(jié)構(gòu)分析與計(jì)算載重汽車轉(zhuǎn)向梯形的結(jié)構(gòu)分析與計(jì)算摘要：摘要：在這個(gè)汽車行業(yè)迅速發(fā)展的大環(huán)境下，汽車的前輪轉(zhuǎn)向梯形結(jié)構(gòu)仍然是汽車轉(zhuǎn)向機(jī)構(gòu)的重要組成之一，它控制著汽車的轉(zhuǎn)向，是汽車轉(zhuǎn)向系中不可缺少的部分。本人通過(guò)對(duì)載重汽車的轉(zhuǎn)向梯形結(jié)構(gòu)原理的分析，對(duì)轉(zhuǎn)向梯形結(jié)構(gòu)簡(jiǎn)圖的繪制與分析，對(duì)主要零部件如：轉(zhuǎn)向梯形的橫拉桿總圖的繪制及橫拉桿球頭的了解得到了以下幾個(gè)方面：汽車在轉(zhuǎn)向的時(shí)候，內(nèi)輪與外輪必須要有正確的轉(zhuǎn)角關(guān)系，這個(gè)關(guān)系對(duì)汽車

2、輪胎的磨損，轉(zhuǎn)向半徑和轉(zhuǎn)向力都有著十分重要的影響。在實(shí)際中不可能完全使輪胎保持純滾動(dòng)所以要對(duì)實(shí)際轉(zhuǎn)角進(jìn)行優(yōu)化計(jì)算。轉(zhuǎn)向橫拉桿是轉(zhuǎn)向梯形的轉(zhuǎn)向傳動(dòng)機(jī)構(gòu)中十分重要的零部件，它的作用就是連接左梯形臂和右梯形臂的，并且致使左梯形臂和右梯形臂協(xié)調(diào)的進(jìn)行工作。轉(zhuǎn)向橫拉桿的斷裂失效平衡模式的相關(guān)問(wèn)題轉(zhuǎn)向橫拉桿球頭的加工工藝問(wèn)題轉(zhuǎn)向梯形機(jī)構(gòu)的動(dòng)態(tài)模擬的相關(guān)問(wèn)題。關(guān)鍵詞：轉(zhuǎn)向梯形，轉(zhuǎn)向橫拉桿，轉(zhuǎn)向橫拉桿球頭，動(dòng)態(tài)模擬Abstract：Undertheen
