Description

Air spring positioning ring with low cost, light weight and easy installation Technical Field The utility model relates to the technical field of air spring positioning rings, in particular to an air spring positioning ring which is low in cost, light in weight and easy to install. Background The air spring retainer ring is used as a key component of a vehicle suspension system, and the performance of the air spring retainer ring directly influences the tightness, the bearing capacity and the assembly efficiency of the air spring. The traditional positioning ring is mostly made of metal materials or solid plastic structures, and has the problems of high material cost, large weight, complex forming process and the like. Especially in the automobile industry with increasingly urgent light-weight demands, the traditional metal locating ring is difficult to meet the energy-saving and emission-reduction requirements, while the existing plastic locating ring can reduce part of weight, but has the defects of overlarge wall thickness, long injection molding cooling time and low production efficiency due to unreasonable structural design. These problems restrict the performance optimization and cost control of the air spring assembly, and there is a need for an innovative structure that combines light weight, low cost and convenience in assembly, and therefore, we propose an air spring positioning ring with low cost, light weight and easy installation. Disclosure of utility model The utility model mainly solves the technical problems in the prior art and provides the air spring positioning ring which is low in cost, light in weight and easy to install. In order to achieve the above purpose, the utility model adopts the following technical scheme that the air spring positioning ring with low cost, light weight and easy installation comprises a positioning ring shell, wherein a connecting ring is integrally formed on the upper side of the positioning ring shell, a second sealing plane is integrally formed on the lower end of the positioning ring shell, a positioning boss is fixedly arranged at the lower end of the second sealing plane, second hollow cavities are formed on the inner sides of the positioning ring shell, the connecting ring and the second sealing plane, a plurality of second hollow cavities are distributed on the inner sides of the positioning ring shell at equal intervals according to the circumference, and a first hollow cavity is formed on the inner sides of the connecting ring corresponding to the upper part of the second hollow cavities.
