Hourglass type air spring assembly

A hourglass type air spring assembly, comprising an upper cover plate, an air bag, an upper end plate and a lower end plate, wherein an outer periphery of the upper cover plate is connected with an outer periphery of the upper end plate through the air bag;

• a low-position hourglass elastomer and a high-position elastomer which are integrally formed are connected with each other between the upper end plate and the lower end plate, and an annular notch is formed between the low-position hourglass elastomer and the high-position elastomer, and an annular rigid partition plate matched with the annular notch is arranged in the annular notch,
• wherein a bottom surface of the annular rigid partition plate is set as a flat surface, and a top surface of the annular rigid partition plate is formed by a flat surface portion and an inclined surface portion;
• the flat surface portion of the annular rigid partition plate is close to an outer periphery of the annular rigid partition plate, and a low position of the inclined surface portion of the annular rigid partition plate is close to an inner ring of the annular rigid partition plate,
• an inner cavity is provided in a center of the low-position hourglass elastomer and a center of the high-position elastomer, and a bottom center of the upper end plate is provided with a stop part extending to the inner cavity.
