汽车使用时间久了后会出现怎样的问题

来源:http://www.sdjnltqf.com发布时间:2022-10-18 15:12:38

1、行驶时车辆转向“发飘”
1. When driving, the vehicle turns to "floating"
故障判定:真故障。
Fault determination: true fault.
原因分析:往往是由行驶中前轮“摆头”引起的,原因有:垫补轮胎或车辆修补造成前轮总成功平衡被破坏;传动轴总成有零件松动;传动轴总成动平衡被破坏;减振器失效;钢板弹簧刚度不一致;转向系机件磨损松驰;前轮校准不当。
Cause analysis: it is often caused by the front wheel "wobble" during driving. The reasons are: the front wheel's total successful balance is damaged due to tire padding or vehicle repair; Loose parts of transmission shaft assembly; Dynamic balance of transmission shaft assembly is damaged; Shock absorber failure; The leaf spring stiffness is inconsistent; The steering system parts are worn and loose; Front wheel alignment is incorrect.
2、汽车在行驶时一遇到故障即引起转向盘摆动,且重车时摆动更严重
2. The steering wheel swings when the vehicle encounters a fault while driving, and the swing is more serious when the vehicle is loaded
故障判定:真故障。
Fault determination: true fault.
原因分析:一般情况下是由于前轮轮胎磨损不均,使用新补的轮胎或垫胎不均及钢圈变形所致。因为,车轮转速较快时,驱动转向盘旋转的力矩主要来自于化胎或钢圈的偏摆度。当轮胎或钢圈的摆差超过3mm时,偏摆力矩就能驱动转向盘左右摆动。
Cause analysis: Generally, it is caused by uneven wear of front tires, uneven use of newly repaired tires or cushion tires, and deformation of steel rims. Because, when the wheel speed is fast, the torque driving the steering wheel to rotate mainly comes from the deflection of the tire or rim. When the runout of the tire or rim exceeds 3mm, the yaw moment can drive the steering wheel to swing left and right.
解决:应去修理厂检查,视情更换化胎或钢圈。
Solution: Go to the repair shop for inspection and replace the chemical tire or steel ring as appropriate.
3、在良好的路面上高速行驶,重空车时转向盘均摆动,重车时摆动严重,且车速越快,摆动越严重
3. When driving on a good road at high speed, the steering wheel swings when the vehicle is loaded and unloaded, and the swing is serious when the vehicle is loaded. The faster the speed is, the more serious the swing is
故障判定:真故障。
Fault determination: true fault.
原因分析:一般是由于制动鼓与轮毂连接螺栓松动,轮毂轴承孔松旷以及制动鼓镗削偏离中心而使制动鼓厚度不一,产生不平衡量所致。
Cause analysis: generally, it is caused by the brake drum thickness and unbalance due to the looseness of the connecting bolts between the brake drum and the wheel hub, the looseness of the wheel hub bearing hole, and the brake drum boring deviation from the center.
解决:应及时到修理厂进行修理。
Solution: go to the repair shop for repair in time.
4、真空胶管有漏气声
4. The vacuum hose leaks
故障判定:真故障。
Fault determination: true fault.
原因分析:在怠速运转时,发动机上部便会听到一种“咝咝”的漏气声,随着转速的提高,声音逐渐消失,冷机热机响声无变化。同时,发动机在怠速运转时,还伴有“突突”声响,有些附件因真空度不够而不工作,响声虽小,但有隐患。上述故障原因是由于真空胶管松动脱落后,因发动机运转产生真空,在真空管接头处有较大的吸气而产生气流的响声。
Cause analysis: When idling, a "hissing" air leakage sound will be heard at the upper part of the engine. With the increase of the speed, the sound gradually disappears, and the sound of cold engine and hot engine remains unchanged. At the same time, when the engine is running at idle speed, there is also a "pop" noise. Some accessories do not work because of insufficient vacuum. Although the noise is small, there is a hidden danger. The reason for the above fault is that after the vacuum hose loosens and falls off, the engine runs to generate vacuum, and there is a large air suction at the vacuum pipe joint, resulting in the sound of air flow.
解决:检查各真空软管管接头处有无老化变形龟裂脱落,若有损坏应更换新件。
Solution: Check whether there is aging, deformation, cracking and falling off at the joint of each vacuum hose. If there is any damage, replace it with a new one.

5、车轮圈发黑
5. Wheel rim blackened
故障判定:假故障。
Fault determination: false fault.
原因分析:车轮圈发黑的原因是制动器在制动时,制动卡钳与车轮盘相互摩擦磨下一些炭粉,这些炭粉如不及时清除,车轮的铝合金轮圈也会发热,这些热量致使炭粉在铝合金轮圈表面结焦,就变成了一层深咖啡色的坚硬表层,用水无法清掉。
Cause analysis: The reason for the blackening of the wheel rim is that when the brake is braking, the brake caliper and the wheel disc rub off some carbon powder. If the carbon powder is not removed in time, the aluminum alloy wheel rim of the wheel will also heat up. The heat causes the carbon powder to coke on the surface of the aluminum alloy wheel rim, which becomes a hard layer of dark brown, and cannot be removed with water.
解决:勤冲洗轮圈。
Solution: wash the rim frequently.
6、转向时沉重费力
6. Heavy and laborious steering
故障判定:真故障。
Fault determination: true fault.
原因分析:原因有转向系各部位的滚动轴承及滑动轴承过紧,轴承润滑不良;转向纵拉杆横拉杆的球头销调得过紧或者缺油;转向轴及套管弯曲,造成卡滞;前轮前束调整不当;前桥车或车架弯曲变形。另外转向轮轮胎亏气四轮定位数据不准也会造成转向沉重。
Cause analysis: the rolling bearings and sliding bearings at various parts of the steering system are too tight, and the bearing lubrication is poor; The ball pin of the steering tie rod is adjusted too tightly or lacks oil; The steering shaft and sleeve are bent, causing seizure; Front wheel toe in is adjusted improperly; The front axle or frame is bent and deformed. In addition, inaccurate four-wheel positioning data of steering wheel tire with air loss will also cause heavy steering.
解决:应及时到修理厂进行更换修理。
Solution: Go to the repair shop for replacement and repair in time.
