Abstract
In an air spring for a railway vehicle or the like, an upper end 3a of the flexible member 3 is attached to the upper face plate 1 at a position that is further on an outer side in a radial direction than the concave section 7. A lower end 3b of the flexible member 3 is attached to the lower face plate 2 at a position that is further on an outer side in a radial direction than the deflation stopper section 5. The deflation stopper section 5 is formed so as to have a height such that the upper end 3a and the lower end 3b of the flexible member do not contact as a result of a relative displacement in the horizontal direction between the upper face plate 1 and the lower face plate 2 at a time of deflation.
Claims5
An air spring, comprising:
- an upper face plate;
- a lower face plate;
- a tubular flexible member that is interposed between the upper face plate and the lower face plate;
- a deflation stopper section that is provided in a condition protruding upward from the lower face plate, and that supports the upper face plate at a time of deflation;
- and
- a concave section that is formed in a center part of an undersurface of the upper face plate, and that sits in the deflation stopper section at a time of deflation;
- wherein:
- an upper end of the flexible member is attached to the upper face plate at a position that is located further on the radially outer side than the concave section;
- a lower end of the flexible member is attached to the lower face plate at a position that is located further on the radially outer side than the deflation stopper section;
- and
- the deflation stopper section is formed so as to have a height such that the upper end and the lower end of the flexible member do not contact as a result of a relative displacement in a horizontal direction between the upper face plate and the lower face plate at a time of deflation.
