Swing arm type independent suspension steering axle

The invention relates to the technical field of automobile damping, and discloses a swing arm type independent suspension steering axle which is characterized in that a cantilever swings up and down through a combined structure of a swing arm, a damping spring and a cylinder type hydraulic damper and bounce generated by wheels when a vehicle passes through an uneven road surface, so that the vehicle is driven to rotate, and the steering axle is driven to rotate. The damping spring and the hydraulic shock absorber are driven to do up-down telescopic motion, damping force generated by the hydraulic shock absorber and buffering force of the damping spring counteract or reduce shock together to achieve the shock absorption effect, meanwhile, the damping hole is arranged to be in a spiral shape, so that when hydraulic oil passes through the spiral damping hole, the flowing path is increased, and the shock absorption effect is improved. The impact force at the inflection point of the spiral hole is increased, and t
