Composition of complex air springs:
Upper steel plate: the upper cover is under pressure and seals the internal air
Waist ring: a stable part of the skin to prevent deformation
Connotation of screw holes: fixed for the installation of air springs in cars or equipment
Inflator/Air Inlet: Air porosity by filling the air-filled air spring
Flexible bellows: main components for locking air up and down and flexible activities
Rubber bumper (optional): Prevents the air spring from colliding with the bottom plate and the bottom plate. You can choose neither
Connotation of screw holes: fixed for the installation of air springs in cars or equipment
Lower steel plate: the lower steel plate is under pressure and seals the internal air
