Description of the Related Art As an air spring used for a vehicle suspension, a rubber film is formed in a substantially cylindrical shape, and an opening at one end is made larger in diameter than an opening at the other end. A rolling sleeve type air spring is known in which a lower small opening is pushed into the inside of a cylindrical portion. FIG. 1 shows this rolling sleeve type air spring 10.
The lower part of the cylindrical main body 11 (the lower part of the main body 1)
3) is folded inward to form a bent portion 12, the upper end opening is fixed to the vehicle body via the receiving plate 17, and the lower end opening is fixed to the axle stand via the piston 18. The rubber film is formed of a fiber cord layer 14 in which a large number of fiber cords made of nylon or polyester (for example, polyethylene terephthalate) are inclined with respect to the circumferential direction of the cylindrical body 11 and arranged in parallel with each other. The upper end is wound from the inside to the outside with respect to the upper bead ring 15 buried along the upper end opening, and the lower end is wrapped from the inside with respect to the lower bead ring 16 buried along the lower end opening. Wound outside. In addition, the air spring 10
Is connected to an auxiliary air chamber or an air supply pipe on the vehicle body through a center hole 17a provided in the receiving plate 17.

いた。In the conventional air spring 10, in order to improve the pressure resistance of the cylindrical body 11, a metal portion is provided at the center thereof, more specifically, at the outer surface of the portion where the outer diameter becomes maximum when the air spring 10 expands and does not bend. Or a band 19 made of FRP, or increasing the number of plies of the fiber cord layer 14,
The arrangement density of fiber cords has been increased, and high-strength cords such as carbon fiber cords, steel cords and glass fiber cords have been used in place of the fiber cords.

When the number of plies of the fiber cord layer 14 is increased, the number of plies in the bent portion 12 becomes the same as the central portion of the cylindrical main body 11, so that the film rigidity of the bent portion 12 is increased and the deformation resistance is increased. Therefore, fatigue tends to occur due to repeated bending, and durability is impaired. In addition, when the arrangement density of the fiber cords is increased, it becomes impossible to secure rubber in the gaps between the fiber cords, and the layers are easily separated. In addition, when a high-strength cord is used, there are problems such as insufficient elongation for reinforcing the air spring, poor flexibility, and high cost.

バンドを嵌めることを不要にしたものである。SUMMARY OF THE INVENTION According to the present invention, in a rolling sleeve type air spring, the number of plies of fiber cords at the center of a cylindrical body is reduced by adjusting the number of plies other than the center of the cylindrical body (the bent portion and the lower portion of the body are reduced). This increases the pressure resistance without increasing the bending resistance at the bending portion, and eliminates the need to fit a ring or a band on the outer surface of the cylindrical main body.

As described in the above, in a rolling sleeve type air spring formed in a cylindrical shape by a rubber film reinforced with a fiber cord layer and having openings at both ends, the air spring is folded back via bead rings provided at each opening at both ends. Both end portions of the fiber cord layer thus formed are overlapped with each other at the center of the cylindrical main body.

The fiber cord layer is formed in a cylindrical shape having a length of at least twice the distance between the upper and lower bead rings, and both end sides thereof are folded back via the bead ring, and the end of the cylindrical body is not bent when used. It overlaps over an area, preferably a width that includes the portion whose outer diameter is greatest when the air spring is inflated. Therefore, when a one-ply fiber cord layer is used, a three-ply structure is formed at a portion where the terminal side is overlapped, and a two-ply structure is formed at other portions. The pressure resistance is increased by about 50% as compared with the air spring, and the bending resistance at the bending portion is almost the same as that of the ordinary vehicle air spring.

It communicates with the auxiliary air chamber or air supply pipe on the vehicle body through the center hole 17a, and as shown in the figure, the lower body portion 23 is folded back along the piston to form a bent portion 22, and the inner space is filled with air and used. Is done. At this time, even if the distance between the receiving plate 17 and the piston 18 fluctuates due to vibration of the traveling vehicle and the bottom of the bent portion 22 moves up and down, since the fiber cord layer 24 has two plies in the bent portion 22,
The bending resistance associated with the movement of the bending portion 22 is not different from that of a conventional two-ply air spring. However, in the portion where the outer diameter D 0 of the central portion of the cylindrical body 21 is maximized, since the fiber cord layer 24 overlap portion 24a of the three-ply is formed, as compared to the air spring of the conventional 2 ply structure 1.5 compressive strength
Up to double. The ends of the fiber cord layer 24 in the three-ply overlapping portion 24a are not fixed to bead rings, but the inner and outer surfaces of the fiber cord layer 24 are covered with topping rubber, and are integrally joined by vulcanization. Therefore, it is fixed to the adjacent layer by the adhesive force between the layers.

面積と内圧の積で示される耐荷力が増大する。When the strength of the fiber cord, the density of the fiber cord when the air spring 20 is inflated, and the inclination angle of the fiber cord with respect to the circumferential direction of the air spring 20 are constant, the pressure resistance of the air spring 20 is as large as that of the cylindrical main body 21. Is proportional to the number of plies of the fiber cord layer 24, and is inversely proportional to the outer diameter D 0 of the cylindrical main body 21. Therefore, the outer diameter D of the air spring 20
When 0 is unchanged, the pressure resistance improves 1.5 times as compared with the conventional two-ply structure as described above. On the other hand, when the pressure resistance constant can increase the outer diameter D 0 to 1.5. Therefore, the 330-340 mm of outer diameter D 0 which is required to suppress in order to obtain a standard value 25 kgf / cm 2 of pressure resistance in the general air spring 20 for a vehicle 380-400
mm , and in this case, the pressure receiving diameter D 1 (see FIG. 2), which is the average value of the outer diameter of the cylindrical main body 21 and the inner diameter of the main body lower part 23, becomes large. And the internal pressure increase.

Moreover, since the end of the fiber cord layer wound around the bead wire is merely extended toward the center of the cylindrical main body, it can be manufactured using conventional manufacturing equipment as it is.
