Fatigue-resistant structure of a vibration-damping axle

Abstract

The utility model discloses a kind of anti-fatigue structures of shock-absorbing shaft, it is related to shock-absorbing shaft technical field, including inner shaft, outer sleeve and anti-fatigue component, the lower end and upper end of the inner shaft are respectively fixed with fixed lower plate, fixed upper plate, the outer side of the inner shaft is provided with anti-fatigue component, and anti-fatigue component includes bellow, shock-absorbing spring, spring washer and airbag layer, the outer side of the inner shaft is attached to bellow, and the outside of bellow is provided with shock-absorbing spring, and the upper and lower ends of shock-absorbing spring are both fixed with spring washer, the spring washer top end of upper side is fixedly connected with fixed upper plate, the spring washer bottom surface of lower side is installed with airbag layer, and the airbag layer is annular structure and located the outer side of inner shaft.The anti-fatigue structure of shock-absorbing shaft, bellow of inner shaft outer side can disperse acting force in the process of axial shock-absorbing, to improve the fatigue strength of inner shaft, and shock-absorbing spring cooperates airbag layer can buffer shock-absorbing, dispersion and absorption energy generated by road surface.
