       说到开车,方向盘是驾驶员接触最多的地方,但是你知道方向盘除了控制汽车方向之外还可以干什么吗?千万不要小看它,很多时候,它在悄悄的向你传达你的爱车可能存在的故障。

  When it comes to driving, the steering wheel is the place where the driver has the most contact, but do you know what the steering wheel can do besides controlling the direction of the car? Don't underestimate it. Many times, it is quietly communicating to you the possible faults of your car.
  一:车辆行驶中手发麻
  I. numbness of hands during driving
  车辆以中速以上速度行驶时,底盘有周期性响声,驶室和车门发抖,方向盘强烈振动,直至于手发麻,这是由于方向传动装置动平衡被破坏,传动轴及其花键轴和花键套磨损过度引起的。
  When the vehicle is running at medium speed or above, the chassis makes periodic noise, the cab and the door shake, and the steering wheel vibrates strongly until the hand becomes numb. This is caused by the damage of the dynamic balance of the steering transmission device and the excessive wear of the transmission shaft and its spline shaft and spline sleeve.
  二:转向时沉重费力
  2. Heavy and laborious steering
  产生原因有转向系各部位的滚动轴承及滑动轴承配合过紧,轴承润滑不良,转向纵拉杆、横拉杆的球头调得过紧或者缺油,转向轴及套管弯曲,造成卡滞;前轮前束调整不当;前轿或车架弯曲,变形;轮胎气压不足,尤其是前轮轮胎。
  The causes are that the rolling bearing and sliding bearing of each part of the steering system are too tight, the bearing is not well lubricated, the ball joints of the steering longitudinal rod and the tie rod are adjusted too tight or lack of oil, the steering shaft and the sleeve are bent, causing stagnation; the front wheel toe in is not adjusted properly; the front car or the frame is bent, deformed; the tire pressure is insufficient, especially the front wheel tires.
  三:方向盘难操纵
  III. steering wheel is difficult to operate
  行驶中或制动时,车辆方向自动偏向道路一边。为保证直线行驶,必须用力握住方向盘,造成车辆跑偏的原因有:两侧的前轮规格或气压不一致,两侧的前轮后倾角或车轮外倾角不相等,两侧的前轮与轴承间隙不一致,两侧的钢板弹簧拱度或弹力不一致,左右两侧轴距相差过大,车轮制动器间隙过小或制动鼓失圆,造成一侧制动器发卡,使制动器拖滞,车辆装载不均匀等。
  When driving or braking, the direction of the vehicle automatically deviates to one side of the road. In order to ensure straight driving, it is necessary to hold the steering wheel firmly. The reasons for vehicle deviation include: the specifications or air pressure of front wheels on both sides are inconsistent, the caster angle or camber angle of front wheels on both sides are not equal, the clearance between front wheels and bearings on both sides is not consistent, the camber or spring force of leaf springs on both sides are not consistent, the wheelbase difference between left and right sides is too large, the wheel brake clearance is too small or the brake drum is lost Round, resulting in one side brake card, brake drag, uneven vehicle loading, etc.
  四:方向发飘
  Four: direction drifting
  往往是由行驶中前轮摆头引起的,当车辆行驶达到某一高速时,出现方向盘发抖或摆振的原因有:垫补轮胎或轮胎修补造成前轮总成动平衡被破坏,传动轴总成有零件松动,传动轴总成动平衡被破坏,减震器失效,钢板弹簧刚度不一致,转向系机件磨损松散,前轮校准不当。
  It is often caused by the front wheel shimmy during driving. When the vehicle reaches a certain high speed, the causes of the steering wheel shaking or shimmy are as follows: the dynamic balance of the front wheel assembly is damaged due to tire pad repair or tire repair, the parts of the transmission shaft assembly are loose, the dynamic balance of the transmission shaft assembly is damaged, the shock absorber is invalid, the rigidity of the leaf spring is inconsistent, the steering system parts are worn loose, and the front wheel is damaged Improper calibration.
