With airbags, many people will feel that this is a safe car accessory. Can often see the owner of Tucao, said that the car was quickly hit the scrapped, and the airbags did not pop up, really pit people. Of course, in the face of such an endless stream of questions, car companies also have their own reasons, airbags will not be any impact will pop up, need to meet some conditions before they start.
Airbag working principle:
Under what circumstances can an airbag be life-saving?
It is a passive safety system device that is only activated when the vehicle is hit hard! The airbag uses the airbag system's pressure sensor and the acceleration sensor in the restraint system ECU to determine whether it should pop up. When both signals are received together, the airbag will be inflated instantly and expand rapidly. Then break the decorative panel of the steering wheel and hit the driver. The upper body of the driver is wrapped in gas, reducing the direct collision between the body and the body, which will greatly reduce the injury rate.
Is the airbag safe?
Under normal circumstances, the volume of the airbag burst is within 130 decibels. The nitrogen in the airbag is also free of toxins and will not harm the human body. But everything has two sides, airbags also have unsafe places, according to the crash test data, when the car speed reaches 60km / h, the airbag pop-up speed is about 5 times the speed, which is 300km / h, which The impact will be nearly 400 pounds. If the angle of the air bag pops up just hits a vulnerable part such as the neck, it may bring danger to the driver.
Airbag under what conditions can start?
At present, there is no standard for the development of airbags in China. Each car company will set its own standards for airbag pop-ups based on the models. Judging from experience, whether the airbag can normally eject is directly related to the impact angle and speed.
For most models, the airbag will open when the following three conditions are met.
1, will meet the set speed will start, such as speed> 50km / h
2. The point of impact of the vehicle must be near the sensor, usually between the front and the right of the vehicle by 60°.
3, the impact of the object must be rigid fixed items, such as stones, walls and other hard objects.
Note: Some models are equipped with the function of not wearing seatbelts and airbags that do not pop up. This is also done to protect the people on the vehicle. When you are not wearing a seatbelt, accidents will pop up if you accidentally. Airbags may give you more damage.
Under normal circumstances, to meet these three conditions, the airbag will automatically pop up, otherwise, no matter how serious traffic accidents, the car's airbags do not necessarily pop up.
Having said so much, in fact, the airbag is only a passive safety configuration, and it needs to be used in conjunction with the safety belt to reduce the risk relatively. It is reported that when a car collides, the airbag can reduce the head injury rate by 1/4 and the face injury rate by 4/5, but it cannot be 100% safe. Therefore, safe driving is the best driving habit. .
Functional features:
The machine is made up of a stepless speed variable winding chuck and a hydraulic lifting platform. No any pit should be construced in foundation and the chuck need not lift. According to customer requirements can be arranged into a pie wire, tensioning unit, accessories and operators could load on the platform, which enables a constant operating altitude. This machine is suitable for regions wit high level of underground water or workshop unsuitable for pit.
Application:
Over floor Vertical Winding Machine is applied to coil winding for large and middle capacity transformers.
