汽车发动机皮带异响的问题分析

发布日期: 2021-03-02 来源: http://www.jnbsx.com/ 点击:

皮带发出吱吱响声,一般情况下代表皮带表面摩擦系数大大降低,已经过度磨损。如果在车辆负载时发出响声,自动变速箱维修厂家小编提醒您不妨观察其中一组传动皮带,你会发现皮带自动松紧装置或皮带松紧轮上的阻力或者说弹力会异常地增加。

The belt squeaks, which generally means that the friction coefficient of the belt surface is greatly reduced and has been excessively worn. If there is a noise when the vehicle is loaded, the automatic transmission maintenance manufacturer reminds you that you may as well observe one group of transmission belts. You will find that the resistance or elastic force on the automatic belt tightening device or belt tightening pulley will increase abnormally.
大多数皮带自动松紧器在其底部与松紧器臂之间,沿着滑道方向的某处有一组皮带磨损长度指示标志。该标志由指针和两到三个标示组成,它标明了皮带松紧器的工作范围。
Most automatic belt tensioners have a set of belt wear length indicators somewhere along the direction of the slideway between the bottom and the arm. The sign is composed of pointer and two to three marks, which indicates the working range of belt tensioner.
如果指针超出了这个范围,那么皮带大概拉伸得过长,应该更换了。在没有安装皮带自动松紧器的车上,在两个皮带轮中间位置用一个标准的皮带伸长量测量尺进行测量。如果与标准值有差异,更好更换皮带。
If the pointer exceeds this range, the belt is probably stretched too long and should be replaced. On the vehicle without automatic belt tensioner, a standard belt elongation measuring ruler is used to measure between two pulleys. If it is different from the standard value, it is better to replace the belt.
如果传动皮带的伸长量并没有超出它的级限值,那么如果你的车安装了自动松紧器的话,你就应该观察它。
If the elongation of the drive belt does not exceed its level limit, then if your car is equipped with an automatic tensioner, you should focus on it.
首先,启动引擎,尽可能给辅助传动配置加负载,然后观察皮带松紧器悬臂;在引擎工作的同时,皮带松紧器悬管应该有一个小小的位移量。如果皮带松紧器悬臂不动,关闭引擎,在皮带松紧器悬管的工作行程之内人工移动它,大概有0.6厘米的位移量。
First of all, start the engine, load the auxiliary drive configuration as much as possible, and then observe the cantilever of the belt tensioner; while the engine is working, the suspension pipe of the belt tensioner should have a small displacement. If the cantilever of the belt tensioner doesn't move, turn off the engine and manually move it within the working stroke of the suspension tube of the belt tensioner, there will be about 0.6cm displacement.
如果皮带松紧器悬臂不能移动,就表明该皮带松紧器失效了,应该及时更换;如果皮带松紧器悬臂的位移量超过0.6厘米左右,说明弹簧负载太小,会使皮带打滑,再测量一次如果还是这样,只有更换皮带松紧器。
If the cantilever of the belt tightener can not move, it indicates that the belt tightener is invalid and should be replaced in time; if the displacement of the cantilever of the belt tightener is more than 0.6cm, it indicates that the spring load is too small and the belt will slip. If it is still the case, the belt tightener must be replaced.
如果皮带并没有过度拉长,而且自动松紧器运作良好,自动变速箱维修厂家讲解这个时候则需要看看皮带的工作表面是否磨得如镜面一样光滑。这是典型的由于皮带磨损过度而引起的在有负载时打滑现象,皮带轮表面脱落的油漆就是打滑现象的证明。
If the belt is not over stretched and the automatic tensioner works well, the automatic transmission maintenance manufacturer should check whether the working surface of the belt is as smooth as a mirror. This is a typical slip phenomenon caused by excessive wear of the belt under load. The paint falling off the surface of the pulley is the proof of the slip phenomenon.
