AI Technical Summary
The existing flat fork structure of electric two-wheelers is prone to deformation and vibration during riding, which affects riding safety and component lifespan. At the same time, it is difficult to achieve a balance between strength improvement and weight reduction.
It adopts a combination structure of horizontal tube, side tube, buffer sleeve, bearing and reinforcement, uses Q235 material, and increases structural strength and reduces weight through welding and optimized design to ensure maximum battery box space.
It improves structural stability and strength, reduces deformation and vibration, lightens vehicle weight, and enhances driving range and handling performance.
