The LLA type non-framework tire coupling is a coupling that is fixed by two half couplings and a tire body through a pressure plate and bolts. The torque transmission is completed by the extrusion and deformation of the tire body.The structure type of tire coupling is divided into frame type, open type, integral type and split type.
