The invention relates to a suspension bridge space large-corner durable sling connecting structure. A sling is tensioned up and down between a cable clamp and a beam end, and includes a cable body, wherein the upper end and the lower end of the cable body are correspondingly anchored in an upper anchor cup and a lower anchor cup; the top of the upper anchor cup and the bottom of the lower anchor cup are respectively provided with a sling ear plate with a pin hole; the sling ear plate at the top end of the sling is rotationally connected with a cable clamp ear plate with a pin hole through a pin shaft, the sling ear plate at the bottom end of the sling is rotationally connected with a beam end ear plate with a pin hole through a pin shaft, a joint bearing is arranged at a matched position of the pin shaft and the pin hole of the ear plate, and the ear plates comprise the sling ear plate, the cable clamp ear plate or the beam end ear plate. When a steel box girder of the sling moves under loads in the bridge direction and the transverse bridge direction, the joint bearing can meet the requirements for rotating swinging and inclined swinging and even composite swinging of the two, sothat the sling is prevented from being bent; the bending stress acting on the sling is eliminated, the degree of freedom of sling deflection is improved, and the stretching and bending fatigue of thesling is reduced.
