Air spring device

An air spring device comprising, as being arranged in a series connection with each other:

• an air spring having a gas-filled interior defined by an upper face plate, a lower face plate, and a cylindrical flexible diaphragm body having end portions connected to the respective face plates;
• a shear spring means including an inner cylinder and an outer cylinder, as well as annular rubber members and annular rigid plates, which are alternately arranged between opposite peripheral surfaces of the inner and outer cylinders, said shear spring means being subjected to a shearing deformation in response to a vertical load;
• and
• a compression spring means including an upper end ring and a lower end support plate, as well as rubber members and rigid plates, which are alternately arranged between the upper end ring and the lower end support plate, said compression spring means being subjected to a compressive deformation in response to a vertical load;
• wherein said air spring means further comprises an abutment portion for restricting a relative displacement between the inner and outer cylinders of the shear spring means in a vertical direction so that a gap is left between the inner cylinder and the lower end support plate when said relative displacement is restricted.
