Abstract
In order to solve the problems existing in a frame in the prior that the stress of the main beam tube is concentrated, the frame generates resonance, the driving comfort is poor, and the frame is easy to fracture and deform, the invention provides a motorcycle frame structure, an upper main beam tube and a lower main beam tube are provided with a first bent part and a second bent part, the upper main beam tube and the lower main beam tube respectively form a first acute angle with a vertical tube part, a second acute angle is formed between the upper main beam tube and the lower main beam tube, and the first acute angle and the second acute angle are arranged oppositely. The beneficial and technical effects of the motorcycle frame structure are that when a vehicle is subjected to road impact, as the upper main beam tube and the lower main beam tube are arranged in a staggered manner, the deformed regions subjected to the maximum stress are distributed in a staggered manner, the stress regions of the upper main beam tube and the lower main beam tube are prevented from concentration, and thus the fracture risk generated by fracture or fatigue stress is lowered. In addition, the vibration, generated by such arrangement when the arrangement is subjected to road roughness vibration impact and the motor operates, makes the forced vibration frequency and the amplitude peak distribute in a staggered manner, the generation of a resonant event is prevented from happening, and the rigidity of the frame is improved.
