我暫時在駕駛一輛舊的Grand Voyager小型貨車,請注意,當我加速後放開加速器時,汽車會向右稍微拉動,我必須向左稍微轉向來糾正它。

我正在查看哪種問題,如果這不能表示單個問題,那麼應該檢查哪些組件以確定問題和嚴重性?

How's the alignment?

該車輛為前輪驅動。 FWD對前輪定位很敏感,因為前懸架和車輪聯動裝置在加速和不加速時會在不同的條件下工作:

  • 在加速時,車輪在道路上向後推動,因此傾向於移動前懸架相對於車輛向前行駛。
  • 在減速時,車輪沿行駛方向朝著路面向前推動,以使車輛減速,反之,則向後推動懸架。

這在RWD車輛中也會發生,但僅限於後軸。因此,加速和轉向之間沒有聯繫。 RWD上的前輪對齊錯誤會隨時改變轉向,而不僅僅是加速。但是,在轉向略微偏離的FWD上,車輪將懸架稍微向一側推,從而產生您所看到的症狀。

最終結果是,該車輛需要前輪對齊被看。如果已經使用了一段時間,則前胎之一的使用量增加且使用不對稱,這很明顯:一側比另一側顯得使用更多。除了使車輛的反應難以預測之外,這還降低了輪胎壽命,因為兩個前輪胎需要同時更換。

我拆下輪胎,檢查了前端懸架和轉向系統,發現駕駛員側的擺桿連桿分離。

That would certainly cause the behaviour you describe! At least it's a relatively simple and inexpensive fix :-)
And I'm sure you also had a good look around the rest of the components too, while the wheels were off. ;-) That bolt looks to have sheared quite some time ago.
Well, this was not the only problem I found after looking behind both wheels. However even after replacing this and an outer tie rod that was loose, the pulling is still there. I'll have to investigate further, but after these changes I at least was satisfied it was safe to drive the distance it needed to go today. It does need an alignment, and I'm guessing the shocks are bad as well.

我在許多車輛和時間上都有這種行為。每次都是由不同的來源引起的。這些包括;

  • 磨損的發動機支架,導致發動機/變速箱總成在節氣門上下運動

  • 在後部磨損車輪軸承,因此存在過多的遊隙,後輪有效地使汽車自身轉向後輪。方形

  • 鬆動的車輪螺栓會導致前輪與輪轂之間的運動

您的問題可能是由以下任何原因引起的以上或類似的東西。我的建議是,首先檢查所有輪胎是否已正確充氣,即使在後部,柔軟的輪胎也會引起操縱不便。然後在9點和3點抓住車輪並嘗試將其移入和移出,然後在12和6進行同樣的操作,檢查是否有任何遊隙。用手旋轉車輪,檢查是否有明顯的東西。

如果仍然沒有結果,請開車進行車輪定位,並將其告知進行定位的機械師。您。

祝您好運!

我的hiluc衝浪(後輪驅動汽車)遇到了同樣的問題,似乎是由於一側的後部折彎(未完全鎖定)導致收緊,每次踩油門時,汽車都會晃動到一邊休息一下

它稱為“扭矩轉向”

該鏈接提供了多種原因和解決方案。

Could you flesh this answer out to what exactly torque steer is and why you think it would be applicable in this case? Link only answers are really frowned upon here as links can become stale.
