奥迪200轿车转向重的主要原因:
The main reasons for steering weight of Audi 200 car are as follows:
1、转向系统零件运动间隙太小，零件变形、缺少润滑，造成运动零件损坏、滞止;
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. 动力转向系统故障。
2. Power steering system failure.
确定维修故障的大致范围，然后进一步排除维修。先用提升机提升车辆,使车辆四个轮子离开地面转方向盘,转向灵活,光,显示驱动系统的故障,应该检查轮胎压力是否过低,四个轮子定位值是不准确的,操舵轴承是否太紧。
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.
如果仍感觉沉重，可以断开转向机与悬挂的连接，然后转动方向盘，如果转向灵活，则认为是转向传动机构的故障，应检查横向拉杆、转向臂或减振器等部件是否弯曲变形。如果转向仍重,动力转向系统的故障,应该检查转向液压油位太低,石油质量是否恶化,如果油位太低,首先检查是否没有泄漏,然后将液压油添加到标准的高度。
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.
如果油品变质必须更换，更换时应注意排气，否则会严重影响动力转向系统的效果。可以用动力转向系统的油压计来测量系统的油压，来判断转向泵的性能。如果转向仍在下沉，则有必要拆卸并检查转向机，看是否存在润滑油不足、锈蚀、齿条弯曲等情况。如果存在上述任何现象，则需要进行必要的维护或更换部件以排除故障。
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.
