1. Excessive pressure: Excessive air pressure in the cab airbag may cause it to harden. This may be caused by airbag system failure or over-inflation. If the pressure of the airbag system is too high, the airbag can not absorb the impact force normally in the event of a collision, thus losing its shock absorption function.
2. Improper airbag assembly: If the airbag is not installed correctly during the assembly process, or the connector is loose or damaged, it may also cause the airbag to harden. In this case, the airbag can not be fully deployed, and the damage caused by the collision to the driver can not be effectively reduced.
3. Aging or damage of airbags: As time goes by, airbags will age or be damaged due to long-term use and environmental factors. Aging or damaged airbags may become hard and lose their normal elasticity and shock absorption function.
Extended content:
Cab airbag is an important part of automobile passive safety system, and its main function is to provide protection for drivers and passengers in automobile collision. The purpose of airbag shock absorption is to reduce the impact on the driver by absorbing and dispersing collision energy, thus reducing the risk of injury.
If the cab airbag suddenly hardens, the driver should stop as soon as possible and check the maintenance problems in time. During driving, always pay attention to the state of the airbag, including observing whether the airbag is abnormally hardened or damaged or whether the warning light is on.
In addition, regular vehicle maintenance is also the key to ensure the normal operation of the airbag system. Drivers should carry out regular maintenance and inspection according to the recommendations of vehicle manufacturers to ensure the reliability of airbag systems and other safety equipment. If problems or anomalies are found, professional and technical personnel should be consulted for maintenance in time.
