載重汽車轉(zhuǎn)向梯形結(jié)構(gòu)分析與計算

1、I載重汽車轉(zhuǎn)向梯形的結(jié)構(gòu)分析與計算載重汽車轉(zhuǎn)向梯形的結(jié)構(gòu)分析與計算摘要：摘要：在這個汽車行業(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。本人通過對載重汽車的轉(zhuǎn)向梯形結(jié)構(gòu)原理的分析，對轉(zhuǎn)向梯形結(jié)構(gòu)簡圖的繪制與分析，對主要零部件如：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方面：汽車在轉(zhuǎn)向的時候，內(nèi)輪與外輪必須要有正確的轉(zhuǎn)角關(guān)系，這個關(guān)系對汽車

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。在實際中不可能完全使輪胎保持純滾動所以要對實際轉(zhuǎn)角進行優(yōu)化計算。轉(zhuǎn)向橫拉桿是轉(zhuǎn)向梯形的轉(zhuǎn)向傳動機構(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)的進行工作。轉(zhuǎn)向橫拉桿的斷裂失效平衡模式的相關(guān)問題轉(zhuǎn)向橫拉桿球頭的加工工藝問題轉(zhuǎn)向梯形機構(gòu)的動態(tài)模擬的相關(guān)問題。關(guān)鍵詞：轉(zhuǎn)向梯形，轉(zhuǎn)向橫拉桿，轉(zhuǎn)向橫拉桿球頭，動態(tài)模擬Abstract：Undertheen
