What is the function of the anti-collision beam?
1 Answers
The function of the anti-collision beam is to absorb and mitigate external impact forces or to protect the front and rear parts of the vehicle body. The anti-collision beam is a U-shaped channel formed by stamping cold-rolled steel plates and is connected to the longitudinal beams of the vehicle frame, serving as the first barrier of passive safety in automobiles. Anti-collision beams are divided into front and rear anti-collision beams. Below is an introduction to the related content: 1. The front anti-collision beam is usually connected to the longitudinal beams of the vehicle body, protecting rear components such as the radiator and reducing damage in minor accidents. The materials are generally steel, fiberglass, or aluminum alloy, with a thickness of 1.5-3mm. In fact, there is usually a layer of foam supporting the outer plastic skin of the front anti-collision beam, primarily serving to protect pedestrians. 2. The rear anti-collision beam is generally thicker than the front beam, around 2-3mm. It is connected to the longitudinal beams under the vehicle chassis, aiming to reduce impact in minor rear-end collisions and protect the thin spare tire rack and rear fenders, among other parts. Without a rear anti-collision beam, even a minor rear-end collision could cause the plastic skin to fail to withstand any impact.
