畢業(yè)論文-汽車轉(zhuǎn)向系檢測維修研究(編輯修改稿)

　

【文章內(nèi)容簡介】 開夾緊箍的緊固螺栓，拆下轉(zhuǎn)向柱下段。 （ 9） 用水泵鉗旋轉(zhuǎn)卸下彈簧墊圈，卸下左邊的內(nèi)六角螺栓，擰出右邊的開口螺栓，拆下轉(zhuǎn)向盤鎖套。 檢查 汽車 檢測與 維修畢業(yè)論文 20 12 檢查轉(zhuǎn)向柱有無彎曲、安全聯(lián)軸節(jié)有無磨損或損壞、彈簧彈性是否失效，如有則應(yīng)修理或更換新件。 安裝 轉(zhuǎn)向柱安裝基本按拆卸的相反順序進(jìn)行，但同時應(yīng)注意以下幾點(diǎn)： （ 1） 轉(zhuǎn)向柱與凸緣管應(yīng)一起安裝，并用水泵鉗連接起來。 （ 2） 應(yīng)將凸緣管 推至轉(zhuǎn)向齒輪軸上，夾緊箍圈口應(yīng)向外。注意：不可用手等 掰開夾箍。 （ 3） 轉(zhuǎn)向柱管的斷開螺栓裝配時，應(yīng)將螺栓擰緊至螺栓頭斷開為止，然后擰緊圓柱螺栓。 （ 4） 車輪應(yīng)處于直線行駛位置，轉(zhuǎn)向指示燈開關(guān)應(yīng)處在中間位置，才可裝轉(zhuǎn)向盤，否則在安裝轉(zhuǎn)向盤時，當(dāng)分離瓜齒通過接觸環(huán)上的簧片時，有可能造成損壞。 （ 5） 應(yīng)更換所有的自鎖螺母和螺栓，轉(zhuǎn)向柱不能進(jìn)行焊接修理。 汽車 檢測與 維修畢業(yè)論文 20 13 4 東風(fēng)愛麗舍（ ELYSEE）汽車故障事例分析 本章講述舉出了愛麗舍轉(zhuǎn)向系中幾種故障現(xiàn)象進(jìn)行了診斷和維修 。 故障事例一 癥狀：倒車 或急轉(zhuǎn)彎時車后輪方向有撞擊聲 。 病因：由于愛麗舍采用了后輪隨動的轉(zhuǎn)向技術(shù)，在使用一段時間后隨動轉(zhuǎn) 向系統(tǒng)的個別螺絲有可能松動。 處方：仔細(xì)檢查，將一些松動的螺絲擰緊后異響即會消失。 故障事例二 狀況：車輛行駛到 8590 公里時速方向盤有微微抖動，超過 90 公里以上又沒了。 解決方法：原因有可能是車輛在行駛過程中發(fā)生的共振。傳動系統(tǒng)各部件在工作時產(chǎn)生微小的抖動是正常現(xiàn)象，此現(xiàn)象與行駛的路況、輪胎的壓力、磨損程度都有直接關(guān)系，車主可以將輪胎進(jìn)行一下?lián)Q位，會有一定的效果。如果是嚴(yán)重的抖動就有可能是輪胎的前束 角出了偏差，這種情況下只能到專業(yè)的修理廠維修。 汽車 檢測與 維修畢業(yè)論文 20 14 結(jié)論 本文介紹了愛麗舍轎車轉(zhuǎn)向系的功能、作用、結(jié)構(gòu)，并通過愛麗舍轎車為例，分析了轉(zhuǎn)向系的故障原因、檢測方法，解決辦法，維修方式，以及如何正確使用、維護(hù)愛麗舍轉(zhuǎn)向器，盡量避免轉(zhuǎn)向器的故障發(fā)生，延長使用壽命 對于現(xiàn)在愛麗舍的 后輪隨動轉(zhuǎn)向技術(shù) 堪稱經(jīng)典 ，匠心獨(dú)具的設(shè)計(jì)師用了一個并不算復(fù)雜的結(jié)構(gòu) ——— “ 后輪的前展和前束 ” ，達(dá)到了一個堪稱經(jīng)典的效果： (1)轉(zhuǎn)向時后輪前展。如果懸掛系統(tǒng)的設(shè)計(jì)使地面給輪船的反作用力誘導(dǎo)后輪胎轉(zhuǎn)向和前輪相 反的方向也就是在負(fù)荷下使后輪前展，這樣將產(chǎn)生一個力矩，加強(qiáng)轉(zhuǎn)動角度使瞬態(tài)轉(zhuǎn)彎中心變小，增加過度轉(zhuǎn)向，在低速時明顯。 (2)轉(zhuǎn)向時后輪前束。如果懸掛系統(tǒng)的設(shè)計(jì)使地面給輪胎的反作用力誘導(dǎo)后輪的轉(zhuǎn)動方向同前輪方向一樣，也就是在負(fù)荷下使后輪前束使瞬態(tài)轉(zhuǎn)彎半徑變大增加不足轉(zhuǎn)向，這樣可以保障方向穩(wěn)定，在高速轉(zhuǎn)彎時特別穩(wěn)。 對于未來我相信雪鐵龍汽車有限公司在愛麗舍的轉(zhuǎn)向技術(shù)方面更高一層次的突破 。 汽車 檢測與 維修畢業(yè)論文 20 15 致謝 光陰似箭轉(zhuǎn)眼間三年的大學(xué)生活即將結(jié)束 ,在這三年的大學(xué)生活中我多次得到老師和同學(xué)們的關(guān)心和幫 助 ,在此我要特向曾經(jīng)幫助過我的老師和同學(xué)表示忠心的感謝。另外在此次論文中我得到我以前最好的一個老師的幫助以及指導(dǎo)老師的 悉心指導(dǎo) ,我的論文才能順利的完成。對此我要向他們表示崇高的敬意。 汽車 檢測與 維修畢業(yè)論文 20 16 參考文獻(xiàn) [1] 劉波，朱俊編著 .汽車轉(zhuǎn)向系維修實(shí)例 [M]北京 :科學(xué)技術(shù)文獻(xiàn)出版社， [2] 張立新主編 .東風(fēng)雪鐵龍系列轎車維修實(shí)例精選 [M]北京 :中國電力出版社， 2022ag an employment tribunal clai Emloyment tribunals sort out disagreements between employers and employees. You may need to make a claim to an employment tribunal if: you don39。t agree with the disciplinary action your employer has taken against you your employer dismisses you and you think that you have been dismissed unfairly.

If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。t charge you more than 35% of your pensation if you win the case. you39。re clear about the terms of the agreement.
