Brief Description Of The Knowledge Of Cross Car Beams

The cross car beams of instrument board is installed at the front of the cab, which is mainly used to fix the instrument panel, support the overall rigidity of the instrument panel assembly, and strengthen the whole cab when the vehicle is colliding.

Therefore, in the vehicle, cross car beam not only plays the role of carrying the instrument panel and some electrical parts, it is also a key part to protect the safety of passengers. For example, it can effectively prevent the deformation of the firewall and hurt the passengers in the collision; To support the knee collision protection, it can provide a buffer absorbing energy space; Supports the fixation of PAB and provides support for the smooth blasting of PAB. Minimize weight while meeting strength requirements and NVH test requirements. The state of the installation of cross car beam on the car will directly affect the installation and matching state of the instrument panel and some appearance parts on it. Therefore, the design of the instrument panel and cross car beam should be rigorously analyzed, the inspection plan should be carefully confirmed, and the manufacturing quality and size should be strictly controlled.
