Description
Technical field
The utility model belongs to rubber air spring, is specifically related to a kind of free sealed type rubber air spring.
Background technique
In existing pneumatic spring, the connection sealing means of air bag is mainly in the majority with the piston type sealing.The piston type sealing mainly is the taper fit face stroke interference fit that makes air bag and upper piston through interior pressure, but debug process is relatively more difficult, and the too big assembling easily of magnitude of interference is not in place, too little easy disengagement.
Summary of the invention
In order to overcome the problems referred to above that the existing technology field exists, the purpose of the utility model is, a kind of free sealed type rubber air spring is provided, and solves relatively difficulty of piston type sealing debug process, and the too big assembling easily of magnitude of interference is not in place, too little easy disengagement.
The free sealed type rubber air spring that the utility model provides, it comprises leather bag, cover plate, shrouding, base, cover plate is connected in the upper end of leather bag; Shrouding is connected in the lower end of leather bag, and the edge of a wing, upper-end surface of shrouding is a tapered edge, is arranged on leather bag inside; With the following rim of the mouth taper fit of leather bag, the shrouding lower end is connected with base, and the base upper end is connected with leather bag; Cover plate edge of a wing volume is pressed in the leather bag, and the edge of a wing forms the flange groove, and the flange groove fastens the last horn mouth of leather bag and is locked in the groove; The inboard that cover plate contacts with leather bag is provided with buffer stopper, suction port, and cover plate, shrouding lower end surface are equipped with fixing bolt.
The free sealed type rubber air spring that the utility model provides; Its beneficial effect is, makes shrouding and leather bag linking together tightly through air pressure, and debugging easily; Simple in structure; Reliability is high, and is easy for installation, and the permission air spring system is laterally done bigger displacement and can not produced air bag and upper sealing plate and throws off and cause gas leakage.
