Tire coupling tire body is a spare part of tire coupling, correspondingly divided into UL, LA, LB tire body.Tire couplings are divided into two categories: convex type and concave type. The convex type is divided into three types: integral type with frame, integral type without bone and radial cut type.The inner side of the tire ring is bonded to the steel frame by a vulcanization method, and the bolt holes on the frame are welded with nuts.When assembling, bolts are used to connect the flanges of the two halves of the coupling, and the torque is transmitted by the friction generated between the tire and the flange end surface by tightening the bolts. The torsional shear deformation of the tire ring occurs when the tire ring is working, so the tire coupling With high flexibility, the ability to compensate the relative displacement of the two axes is great
