It is easy to understand this pressure literally, part of the Changan Car non-suspension weight. Therefore, the longitudinal beams and cross beams at the bottom of the Petrol Car frame generally require strong rigidity.
When the front and rear diagonal wheels encounter unevenness on the road and roll, the beams of the Petrol Car frame will bear this longitudinal torsion pressure, just like asking you to twist a piece of plastic into a spiral.
3) Lateral bending
4) Horizontal diamond torsion
Because when the Petrol Car is driving, each wheel will bear different resistance and traction due to different road surfaces and driving conditions (road paving conditions, bumps, obstacles, and entering and exiting corners, etc.), which can cause the Petrol Car frame to push and pull in the horizontal direction and even deform, which is like pulling a rectangle into a diamond.
Checking the frame of a Petrol Car to identify an accident vehicle. When we choose a used car, checking the frame number of the Petrol Car is the most important item. As consumers, we do not have accurate experience and must find someone who knows how to repair it to help. For us consumers, checking the frame of a Changan Car parts can identify whether it is an accident vehicle.
