What is car air bag spring
automotive air bag spring , also known as clock spring , is an important part of connecting the main air bag and the air bag harness. It is mounted inside the steering wheel, in the honking position. Since the main air bag will move with the rotation of the steering wheel, the spring needs to be cleverly wrapped around the steering wheel and turn flexibly with the steering wheel. Therefore, when connecting the air bag harness, the design of the spring needs to leave a certain margin to avoid being pulled off during use.
The function and function of air bag spring
ensures current supply : The air bag spring ensures that the current can still enter the airbag when the steering wheel is rotating, and ensures the normal power supply of the electrical equipment on the steering wheel assembly.
adapt to steering wheel rotation : Since the main air bag needs to rotate with the steering wheel, the spring needs to be able to expand and expand with the rotation of the steering wheel to adapt to the rotation of the steering wheel.
Protecting the driver : Air bags on the steering wheel deploy quickly to protect the driver in the event of a crash. The design and installation position of the spring ensures that the airbag harness is not damaged, thus ensuring the normal deployment of the airbag.
Installation position and maintenance precautions
mounted in the middle of the steering wheel : In order to ensure that the spring will not break when the steering wheel is turned to the limit position, the spring is usually installed in the middle of the steering wheel.
leave a margin : When connecting the harness, the spring needs to leave a certain margin to prevent the steering wheel from being pulled off.
Through the detailed explanation of these functions and installation positions, the important role of the air bag spring in the automotive safety system can be better understood.
The main function of the air bag spring is to connect the main air bag and the air bag harness, to ensure that the current can be smoothly transmitted when the steering wheel rotates, so as to ensure that the air bag can work normally when the vehicle crashes, and to protect the safety of drivers and passengers .
Specifically, an air bag spring (also known as a coil spring) is a specially designed harness of wire that wraps around the steering wheel, extending and contracting as the wheel turns. This design ensures that when the steering wheel is rotated to the limit position, the spring will not be pulled, thus ensuring the stable transmission of current . In addition, the air bag spring has a constant contact resistance, which is more reliable than other systems with slip rings, and a short circuit lap is installed at the wire junction to prevent accidental detonations .
If the air bag spring malfunctions, it may cause the airbag to fail to function properly, thus failing to provide effective protection in the event of a crash. Common fault manifestations include airbag light, car horn does not sound, steering wheel sound control keys cannot be used .
Therefore, it is very important to regularly check and maintain the state of the air bag spring.
