1) on the uneven road, the vehicle causes the vertical impact load of the frame, which exceeds the allowable stress of the frame. In addition, in the car downhill, turn or load uneven, also will cause North Ben V3 parts frame overload and cause frame fracture.
2) frame design or attachment causes local torque to break the frame. If the front frame rails of small cross section, at the same time, due to the impact of the engine and transmission, so the beam distribution less stiffness to the frame difference, if under the dynamic loads, may cause the beam front fault, is common in the longitudinal fracture under the wing. In addition, the frame is also affected by the vertical load for the cantilever beam (such as tank, suspension and tire etc.) local distortions generated, but also caused a fracture.
3 when driving, North Run V3 accessories front wheel side by a lot of resistance, so that the frame prone to diagonal plane deformation.
4 car crash, serious impact will cause frame deformation
North Benz V3 car chassis parts deformation is that the frame changed the original geometry, which makes the installation on the frame of the assembly parts relative position change, deterioration of technology condition of the introduction of the engineering vehicle, causing the vehicle can not be normally running. Frame deformation often due to the force acting on the frame exceeds its elastic limit, as the frame for the frame after the elimination of force can not restore the original state, forming a residual deformation.
