汽车例行保养中经常被忽略的几处部件

来源:http://www.sdjnltqf.com发布时间:2022-11-10 13:50:33

济南大众汽车维修哪里有厂家提醒车友,在车辆的运行过程中,很多部件都在不断地磨损,例行保养、检查范围也远远不限于三滤、机油、刹车片、火花塞等,很多地方如果平时不注意检查、维护,说不定什么时候就会出现意想不到的故障。面是在例行保养中经常被忽略的几处部件:
Where did the manufacturer of Jinan Volkswagen repair remind motorists that during the operation of the vehicle, many parts are constantly worn, and the scope of routine maintenance and inspection is far beyond the three filters, engine oil, brake pads, spark plugs, etc. In many places, if you do not pay attention to inspection and maintenance at ordinary times, unexpected faults may occur at some time. The surface is a few parts that are often ignored in routine maintenance:
1、点火线。
1. Ignition wire.
很多人都知道火花塞要定期更换,但却忽略了点火系统其它部件的维护,点火高压线就是其中之一。在发动机运转时,点火线上经常有数万伏的高压脉冲电流,由于它长时间工作在高温、多尘、振动的环境中,不可避免地要发生老化甚至破损。
Many people know that the spark plug should be replaced regularly, but they neglect the maintenance of other parts of the ignition system, and the ignition high-voltage wire is one of them. When the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the ignition line. Because it works in a high temperature, dusty and vibrating environment for a long time, it will inevitably be aged or even damaged.
根据经验,即使没有任何故障,点火高压线每隔两万公里左右也需要更换一套。而国内很多车主往往要等到发动机出现运转不稳甚至无法启动的故障时才想起检查点火系统,但到了这时,由于点火系统部件潜在损坏而浪费的燃油和对发动机造成的磨损已远远超过了它自身的价值。
According to experience, even if there is no fault, the ignition high-voltage line needs to be replaced every 20000 km or so. However, many domestic car owners often wait until the engine is unstable or even unable to start to check the ignition system, but at this time, the fuel wasted due to potential damage of ignition system components and the wear caused to the engine have far exceeded its own value.
此外,点火系统中的分电器盖、分火头、点火线圈、火花塞插头等部件也应在例行保养、检查范围之内。
In addition, the distributor cover, distributor, ignition coil, spark plug plug and other components in the ignition system shall also be within the scope of routine maintenance and inspection.

2、制动盘。
2. Brake disc.
制动盘与制动蹄片是一对摩擦副,制动蹄片磨损了,制动盘也会有一定的磨损,这个道理是很浅显的,但很多人在保养车辆时只注意更换蹄片,却常常忽略了更换制动盘。
The brake disc and brake shoe are a pair of friction pairs. When the brake shoe is worn, the brake disc will also be worn, which is very simple. However, many people only pay attention to replacing the shoe when maintaining the vehicle, but often neglect to replace the brake disc.
制动盘过度磨损带来的后果是很严重的,由于表面平整度降低,使实际的接触面积变小,造成制动力不足;另外,磨损后的制动盘热容量降低,在持续制动时温度升高很快,更容易产生热衰退现象。所有这些在行驶中都是非常危险的。
The consequences of excessive wear of the brake disc are very serious. Due to the reduction of surface flatness, the actual contact area becomes smaller, resulting in insufficient braking force; In addition, the thermal capacity of the worn brake disc decreases, and the temperature increases rapidly during continuous braking, which is more likely to cause thermal recession. All these are very dangerous when driving.
有些修理厂把磨损严重的制动盘放在车床上作表面处理,俗称“光盘”,这样一来,表面是平整了,但盘变得更薄,制动时的热衰退现象会更严重,另外,在加工过程中产生的高温会使制动盘退火,进一步降低了机械强度。
Some repair shops put the severely worn brake disc on the lathe for surface treatment, commonly known as "disc". In this way, the surface is flat, but the disc becomes thinner, and the heat recession during braking will be more serious. In addition, the high temperature generated during processing will make the brake disc backfire, further reducing the mechanical strength.
一般来说,在制动蹄片更换2-3次之后,制动盘也应更换。千万别心疼这几百块钱,毕竟,人的生命是无价的。
Generally speaking, the brake disc shall be replaced after the brake shoe is replaced for 2-3 times. Don't be distressed by these hundreds of dollars. After all, human life is priceless.
俗话说,“小洞不补,大洞吃苦”,保养时花上几十块钱,也许就能为将来省下几百、上千元甚至更多。为了安全着想,也要固定时期进行例行保养,更多相关内容就来我们网站http://www.sdjnltqf.com咨询看看吧!
As the saying goes, "A small hole does not mend, but a big one does". If you spend tens of dollars on maintenance, you may save hundreds, thousands or even more in the future. For the sake of safety, routine maintenance should also be carried out at regular intervals. More relevant information can be found on our website http://www.sdjnltqf.com Consult!
