奧迪200轎車轉向重的主要原因:
The main reasons for steering weight of Audi 200 car are as follows:
1、轉向系統(tǒng)零件運動間隙太小，零件變形、缺少潤滑，造成運動零件損壞、滯止;
1. The movement clearance of steering system parts is too small, the parts are deformed and lack of lubrication, which results in the damage and stagnation of the moving parts.
2. 動力轉向系統(tǒng)故障。
2. Power steering system failure.
確定維修故障的大致范圍，然后進一步排除維修。先用提升機提升車輛,使車輛四個輪子離開地面轉方向盤,轉向靈活,光,顯示驅動系統(tǒng)的故障,應該檢查輪胎壓力是否過低,四個輪子定位值是不準確的,操舵軸承是否太緊。
Determine the general scope of maintenance failure, and then further eliminate maintenance. Firstly, the hoist is used to lift the vehicle so that the four wheels of the vehicle leave the ground to turn the steering wheel. The steering is flexible and the light shows the fault of the driving system. Whether the tire pressure is too low, the four wheels'positioning value is inaccurate, and whether the steering bearing is too tight should be checked.
如果仍感覺沉重，可以斷開轉向機與懸掛的連接，然后轉動方向盤，如果轉向靈活，則認為是轉向傳動機構的故障，應檢查橫向拉桿、轉向臂或減振器等部件是否彎曲變形。如果轉向仍重,動力轉向系統(tǒng)的故障,應該檢查轉向液壓油位太低,石油質(zhì)量是否惡化,如果油位太低,首先檢查是否沒有泄漏,然后將液壓油添加到標準的高度。
If you still feel heavy, you can disconnect the connection between the steering gear and the suspension, and then turn the steering wheel. If the steering is flexible, it is considered to be a fault of the steering transmission mechanism. Whether the transverse tie rod, steering arm or shock absorber are bent or deformed or not should be checked. If the steering is still heavy and the power steering system fails, it should be checked whether the steering hydraulic oil level is too low and the oil quality deteriorates. If the oil level is too low, first check whether there is no leakage, and then add the hydraulic oil to the standard height.
如果油品變質(zhì)必須更換，更換時應注意排氣，否則會嚴重影響動力轉向系統(tǒng)的效果。可以用動力轉向系統(tǒng)的油壓計來測量系統(tǒng)的油壓，來判斷轉向泵的性能。如果轉向仍在下沉，則有必要拆卸并檢查轉向機，看是否存在潤滑油不足、銹蝕、齒條彎曲等情況。如果存在上述任何現(xiàn)象，則需要進行必要的維護或更換部件以排除故障。
If oil deterioration must be replaced, attention should be paid to exhaust when replacing, otherwise the effect of power steering system will be seriously affected. The hydraulic pressure of the power steering system can be measured by the hydraulic pressure gauge to judge the performance of the steering pump. If the steering is still sinking, it is necessary to disassemble and check the steering gear to see if there is insufficient lubricant, rust, rack bending and so on. If any of the above phenomena exist, the necessary maintenance or replacement parts are required to eliminate the failure.
