The invention discloses a belt bundle type capsule and an air spring with the capsule. The belt bundle type capsule comprises an upper cover and a capsule body. The capsule body is installed below the upper cover. A belt part is arranged on the vertical part of the middle section of the capsule body. The capsule body is of a hollow structure, and an annular opening is formed in the top of the capsule body. The belt bundle type capsule further comprises a connecting piece connecting the capsule body and the upper cover. The top of the capsule body is connected with the connecting piece, and the connecting piece is connected with the upper cover. The capsule body comprises a section of belt bundle structure. The belt bundle structure is adopted for replacing a steel wire belt structure, and the total weight of the air spring is reduced; and the width of a belt bundle layer is in gradual transition, and the problem that stress at the two ends of a steel wire belt of a belt type air spring are concentrated is effectively solved. The connecting piece is designed, the connecting mode of seam allowances on the capsule is changed, and the capsule recovers easily and resists abrasion.
