汽車傳動軸常見的故障有哪些？和傳動軸聯軸器的小編簡單了解。

傳(chuan)動(dong)軸(zhou)(zhou)機件(jian)的(de)(de)損壞、磨損、變形(xing)以及(ji)失去動(dong)平衡，都會(hui)(hui)造成汽車在(zai)(zai)行駛中產生(sheng)異(yi)響和(he)振動(dong)，嚴重時會(hui)(hui)導(dao)致相關部件(jian)的(de)(de)損壞。汽車行駛中，在(zai)(zai)起步或急加速(su)(su)時發出“格登”的(de)(de)聲響，而且明(ming)顯(xian)表現出機件(jian)松(song)(song)(song)曠(kuang)的(de)(de)感覺，如果(guo)不(bu)是驅(qu)動(dong)橋傳(chuan)動(dong)齒(chi)輪松(song)(song)(song)曠(kuang)則顯(xian)然是傳(chuan)動(dong)軸(zhou)(zhou)機件(jian)松(song)(song)(song)曠(kuang)。松(song)(song)(song)曠(kuang)的(de)(de)部位不(bu)外乎是萬向節十(shi)字軸(zhou)(zhou)承或鋼碗與凸緣叉，伸(shen)縮套的(de)(de)花(hua)鍵(jian)(jian)軸(zhou)(zhou)與花(hua)鍵(jian)(jian)套。一般(ban)來(lai)講，十(shi)字軸(zhou)(zhou)軸(zhou)(zhou)徑與軸(zhou)(zhou)承曠(kuang)量不(bu)應超過0.13mm,伸(shen)縮花(hua)鍵(jian)(jian)軸(zhou)(zhou)與花(hua)鍵(jian)(jian)套嚙(nie)合間(jian)(jian)隙不(bu)應大于0.3mm。超過使用極限應當(dang)修(xiu)復或更換(huan)。傳(chuan)動(dong)軸(zhou)(zhou)中間(jian)(jian)吊架(jia)的(de)(de)安(an)裝在(zai)(zai)維(wei)修(xiu)中十(shi)分重要。如果(guo)吊架(jia)安(an)裝位置(zhi)不(bu)當(dang)，會(hui)(hui)增加傳(chuan)動(dong)軸(zhou)(zhou)運轉(zhuan)阻力和(he)噪聲，導(dao)致軸(zhou)(zhou)承的(de)(de)早期損壞。在(zai)(zai)重新安(an)裝吊架(jia)時，首先將吊架(jia)固定(ding)螺栓(shuan)不(bu)要擰(ning)緊，將汽車驅(qu)動(dong)輪用千斤頂(ding)支離地面，掛低(di)速(su)(su)檔，慢慢旋轉(zhuan)傳(chuan)動(dong)軸(zhou)(zhou)使傳(chuan)動(dong)軸(zhou)(zhou)和(he)吊架(jia)自動(dong)找(zhao)正，然后再將吊架(jia)固定(ding)螺栓(shuan)擰(ning)緊。

汽(qi)車(che)(che)行駛(shi)中(zhong)(zhong)若底(di)盤發生“嗡(weng)嗡(weng)”聲(sheng)，而且運(yun)行速度越(yue)高，聲(sheng)音越(yue)大(da)。這一(yi)般是(shi)(shi)由于萬(wan)向節十(shi)字(zi)軸與軸承(cheng)磨(mo)損(sun)(sun)松曠、傳(chuan)(chuan)動(dong)軸中(zhong)(zhong)間軸承(cheng)磨(mo)損(sun)(sun)、中(zhong)(zhong)間橡膠支承(cheng)損(sun)(sun)壞(huai)或吊架(jia)松動(dong)，或是(shi)(shi)由于吊架(jia)固定的位(wei)置(zhi)不(bu)對所致；6×4汽(qi)車(che)(che)在重負荷時，特別在行駛(shi)顛簸中(zhong)(zhong)偶爾發出敲擊聲(sheng)，應注意檢查中(zhong)(zhong)后橋(qiao)平衡(heng)(heng)(heng)軸是(shi)(shi)否變位(wei)而與傳(chuan)(chuan)動(dong)軸發生干(gan)涉。汽(qi)車(che)(che)運(yun)行中(zhong)(zhong)若隨著(zhu)車(che)(che)速的增高而噪聲(sheng)增大(da)，并(bing)且伴隨有抖動(dong)，這一(yi)般是(shi)(shi)由于傳(chuan)(chuan)動(dong)軸失(shi)去平衡(heng)(heng)(heng)所致。這種(zhong)振動(dong)在駕駛(shi)室內感覺較(jiao)為明(ming)顯。傳(chuan)(chuan)動(dong)軸動(dong)平衡(heng)(heng)(heng)的不(bu)平衡(heng)(heng)(heng)量(liang)應小于100 g. cm；傳(chuan)(chuan)動(dong)軸動(dong)平衡(heng)(heng)(heng)失(shi)效嚴重會導(dao)致相(xiang)關(guan)部件的損(sun)(sun)壞(huai)。常(chang)見的是(shi)離合器殼裂紋和(he)中間橡(xiang)膠支承的疲(pi)勞損壞。
