Where is the beam of the car located?

[StElle]

Under the car body, there are two channel steels running from the front to the rear of the vehicle, which mark the position of the car beam. Below is a detailed introduction to the car beam: 1. The beam, also known as the frame, is the base of the car. It generally consists of two longitudinal beams and several cross beams, supported on the wheels via suspension devices, front axle, and rear axle. 2. The car beam is part of the car's chassis structure. However, most modern cars no longer use a beam-type chassis design, except for trucks and buses. The car beam is the main load-bearing component of a truck, carrying almost the entire weight of the cargo. The quality of the beam affects the vehicle's lifespan and driving safety. The manufacturing of car beams typically uses stamping forming processes, with bending as the primary deformation method. Therefore, the beam plate requires high formability, meaning the car beam steel plate must have excellent comprehensive performance, sufficient strength and toughness, good fatigue resistance, and cold formability. 3. The car beam provides strong body rigidity and enhances safety, which is particularly important for heavy-duty vehicles and off-road vehicles.
