扭力扳手的用处也是特别多的，包括现在的汽车维修方面也会用到扭力扳手，车上每颗螺丝都有标准扭矩，拆卸安装螺丝标准的操作应该使用扭矩扳手，轮胎螺丝也有标准扭矩，这两处是整个车拆装比较频繁的螺丝，但是维修技师一般都会用普通的扳手去紧固，时间长了油底壳螺丝就坏了，这不是因为拆卸次数多造成的，是因为紧固时没有用扭矩扳手，导致螺丝的过拧而造成的。所以在维修的时候可以选用扭力扳手，小编给大家总结了一些扭力扳手的好处，大家可以看一下
Torque wrenches are also very useful. Torque wrenches are also used in current automobile maintenance. Each screw on the car has a standard torque. Torque wrenches should be used for standard operation of removing and installing screws. Tire screws also have a standard torque. These two screws are frequently disassembled and disassembled in the whole car, but maintenance technicians usually use ordinary wrenches to tighten them, The oil pan screws broke after a long time. This is not caused by too many disassembly times, but because the screws were over tightened without a torque wrench. Therefore, torque wrench can be selected during maintenance. Xiaobian summarized some benefits of torque wrench for you to have a look
为什么有些维修技师不太爱用扭矩扳手？有三方面原因，一是经验丰富，对力矩的把握比较准确，也知道紧固这个螺丝需要用多大的力，紧固完后与标准扭矩相差无几。二是偷懒的做法，用扭矩扳手紧固比较麻烦，每次紧固螺丝都要去调整。三是大部分螺丝就算没有达到标准扭矩，影响也不大，不会影响车的使用。
Why do some maintenance technicians not like to use torque wrench? There are three reasons. First, he has rich experience and has a relatively accurate grasp of the torque. He also knows how much force it takes to tighten the screw. After tightening, it is almost the same as the standard torque. Second, it is lazy. It is troublesome to tighten with a torque wrench. The screws must be adjusted every time. Third, even if most screws do not reach the standard torque, the impact is not great and will not affect the use of the car.
如果每次都不按标准扭矩来，时间久了有什么危害呢？我们就拿油底壳螺丝来说，如果扭矩太小，会有渗油现象。扭矩太大，螺丝会被拉长，久而久之也会渗油，甚至螺丝还会断裂。更严重的还会把丝圈损坏，不只是要更换螺丝，还要对油底壳重新套丝，工程量比较大。实际上紧固油底壳螺丝，绝大部分人都会超过标准扭矩，也就是紧固的太紧了，甚至下次拆卸都不容易拆。有的拆下来直接就拆坏了，这就是上次紧固太紧造成的。油底壳螺丝大约也就二三十牛米的力矩，用很小的力紧一下就可以。轮胎螺丝也是相同的道理，很多轮胎螺丝断了或者拆不下来，都是上次紧固时用的力太大了造成的。不管哪里的螺丝，只要没有用扭力扳手紧固的，大部分都会拧得过紧，超过标准扭矩。
If you don't follow the standard torque every time, what harm will it do after a long time? Take the oil pan screw for example. If the torque is too small, there will be oil leakage. If the torque is too large, the screw will be elongated, oil will leak over time, and even the screw will break. Even more serious, the wire ring will be damaged. It is not only necessary to replace the screws, but also to re thread the oil pan, with a large amount of work. In fact, when tightening the oil pan screws, most people will exceed the standard torque, that is, the tightening is too tight, and it is not easy to remove them next time. Some of them are broken when they are removed. This is because they were tightened too tightly last time. The torque of the oil pan screw is about 20 or 30 nm. Tighten it with a small force. The same is true for tire screws. Many tire screws are broken or cannot be removed, which is caused by too much force when tightening last time. No matter where the screws are, as long as they are not tightened with a torque wrench, most of them will be over tightened and exceed the standard torque.
所以关键部位还是需要用到扭力扳手，比如缸盖螺丝，大小瓦螺丝。还有比较常见的气门室盖螺丝，很多车气门室盖垫容易漏油，更换需要拆卸气门室盖。因盖子上螺丝非常多，如果不用扭力扳手，会导致每颗螺丝的力矩不一样大，也就是有的紧有的松，这样会导致气门室垫寿命缩短，用不了多长时间又会渗油。而用扭力扳手可以 工作的质量，避免出现后续的纠纷
Therefore, torque wrenches are still needed in key parts, such as cylinder head screws and large and small tile screws. There are also common valve cover screws. The valve cover gasket of many vehicles is easy to leak oil. The valve cover needs to be removed for replacement. Because there are many screws on the cover, if you don't use a torque wrench, the torque of each screw will be different, that is, some are tight and some are loose, which will shorten the service life of the valve pad and leak oil in a short time. The use of torque wrench can improve the quality of work and avoid subsequent disputes
