检修及分析汽车方向盘抖动原因

来源:http://www.jnrunao.com/ 日期:2021-04-20 发布人:runao
1.汽车行驶时,因碰撞使转向拉杆及转向横拉杆变形,各部位球头磨损松动或轮胎磨损不规则,使车轮前束增大或缩小。
1. When the car is running, the steering rod and tie rod are deformed due to the collision, the ball joint of each part is worn loose or the tire is worn irregularly, which makes the toe in of the wheel increase or decrease.
2.汽车行驶时,由于转向减震损坏,漏油或前挂弹簧变形。
2. When the car is running, due to steering shock absorption damage, oil leakage or front suspension spring deformation.
3.轮毂轴承松动及左右转向节球头磨损严重。
3. The hub bearing is loose and the ball heads of the left and right steering knuckles are seriously worn.
4.横向推力杆球头松动或支架松动。
4. The ball head of transverse thrust rod is loose or the bracket is loose.
5.车轮不平衡,原车轮的平衡铅掉了或变形造成高速行车的状态下车头发摆。
5. The wheel is not balanced, the balance lead of the original wheel is lost or deformed, which causes the hair to swing when driving at high speed.
需要注意的是,方向盘作为整车非常重要的控制部分之一,它与很多方面都有关联。从另一角度讲,很多其他的故障也可以通过方向盘表现出来。图片
It should be noted that the steering wheel, as one of the most important control parts of the whole vehicle, is related to many aspects. On the other hand, many other faults can also be shown through the steering wheel. picture
中速以上行驶时,方向盘强烈抖动的车辆,底盘有周期性异响,很可能是因为方向传动装置的平衡被破坏,传动轴及其花键轴和花键套过度磨损。
When driving at medium speed or above, the chassis of the vehicle with strong shaking steering wheel has periodic abnormal noise. It is likely that the balance of the steering transmission device is damaged, and the transmission shaft and its spline shaft and spline sleeve are excessively worn.
转向时感觉沉重费力,可能是转向系各部位的滚动轴承配合过紧,轴承润滑不良,转向横直拉杆的球头过紧或缺油;此外,前轮轮胎气压不足,也可能导致这一情况的出现。
When steering, I feel heavy and laborious. It may be that the rolling bearings of various parts of the steering system are too tight, the bearing lubrication is poor, the ball head of the steering tie rod is too tight or lack of oil; in addition, the insufficient tire pressure of the front wheels may also lead to this situation.
制动跑偏,可能是由于两侧的前轮规格或者气压不一致造成的;而两侧的前轮倾角不相等、前轮轴承间隙不一致或轴距相差过大也可能造成这种情况。
The brake deviation may be caused by the inconsistency of the specifications or air pressure of the front wheels on both sides; the unequal inclination of the front wheels on both sides, the inconsistency of the front wheel bearing clearance or the large difference of wheelbase may also cause this situation.
高速行驶发飘,往往是由于行驶中前轮摆头引起的。不过,垫补轮胎或轮胎维修造成前轮总成动平衡被破坏、减振器失效、转向系机件磨损松脱以及前轮校准不当等因素,也可能造成这种结果。
When driving at high speed, it is often caused by front wheel shimmy. However, the dynamic balance of the front wheel assembly is damaged, the shock absorber is invalid, the parts of the steering system are worn and loose, and the front wheel is not calibrated properly due to pad tire or tire repair.
