Abstract

The utility model provides a suspension type train rubber air spring, which is similar in the shape of a car tyre, the tyre wall is formed that a cord fabric layer 6 is hold between an outer layer of glue 5 and an inner layer of glue 2, a round big opening 1 and a small opening 7, the diameters of the round big opening and the small opening are different are respectively arranged on the center parts of the top fundus and the bottom fundus of the tyre wall. A round big wire ring 3 and a small wire ring 8 are respectively arranged on the edges of the big opening 1 and the small opening 7. The peripheries of the two wire rings are wrapped with cushion rubber 4 and cushion rubber 9. The utility model provides the suspension type train rubber air spring which can replace the steel plate spring, has low noise and excellent safety, can facilitate the train to be stable and comfortable, and can be widely used in the damping of the train.

Description

Suspension-type train rubber air spring

Technical field:

The utility model relates to a kind of vapour train, subway damping spring.

Background technology:

At present, train, subway are for damping, and the past is used traditional steel spring or coiling spring always, has defectives such as frangibility, flexibility is poor, traveling comfort is poor, vibration is big.

Summary of the invention:

The purpose of this utility model will provide a kind of exactly can replace steel spring, and noise is little, safety good, can make the comfortable suspension-type train rubber air spring of train smooth.

The technical solution of the utility model is achieved in that a kind of suspension-type train rubber air spring, be characterized in: it is similar to motor tire, tyre sidewall is formed by accompanying carcass plies 6 between outer layer glue 5 and the hose lining 2, upper base at it has diameter different circular big rim of the mouth 1 and boy's mouth 7 with the centre of going to the bottom, in the mouth edge of big rim of the mouth 1 and boy's mouth 7, big bead coil 3 of annular arrangement and little bead coil 8 are housed, all are enclosed with cushion compound 4 and cushion compound 9 in two bead coil peripheries.

The utility model is pressed as long as change in its air, just can obtain different load-carrying capacitys, utilize the height-control valve of air bellow can make it under certain loading, have different height to adapt to the demand of multiple structure, the rigidity of air bellow with in be pressed into direct ratio, so its rigidity is variable; Rubber air spring has non-linear, its characteristic curve (load---sag curve) can be designed to perfect condition; Rubber air spring links to each other with additive air, can make the eigentone of its device be reduced to minimum, under the effect of any load, rubber air spring all keeps lower and intimate equal oscillation frequency, constitute by air and rubber, it is little to rub, and can not influence the ability of isolating high-frequency vibration because of intrinsic vibration; Do not have intermetallic contact, therefore isolate soundproof effective; Add a cutoff port between rubber air spring and additive air, when vibration took place load on the spring, windstream was through cutoff port generation degradation of energy, thereby played the effect of damped vibration; The fatigue performance of rubber air spring is better than metal spring manyfold, long service life; The utility model is easy to manufacture, and installation is changed conveniently, maintaining is simple, does not need frequent maintenance, need not to refuel.

Description of drawings:

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

Specific embodiments:

From Fig. 1, Fig. 2 as seen: the utility model likeness in form motor tire, the wheel wall is to constitute by filling carcass plies 6 between outer layer glue 5 and the hose lining 2, have circular big rim of the mouth 1 and boy's mouth 7 in upper base and the centre of going to the bottom, along interior big bead coil 3 of annular arrangement and the little bead coil 8 of being equipped with respectively, all be enclosed with cushion compound 4 and cushion compound 9 at the mouth of big rim of the mouth 1 and boy's mouth 7 in two bead coil peripheries.

Claims

1, a kind of suspension-type train rubber air spring, it is characterized in that: it is similar to motor tire, tyre sidewall is formed by accompanying carcass plies (6) between outer layer glue (5) and the hose lining (2), upper base at it has diameter different circular big rim of the mouth (1) and little rim of the mouth (7) with the centre of going to the bottom, in the mouth edge of big rim of the mouth (1) and little rim of the mouth (7), big bead coil of annular arrangement (3) and little bead coil (8) are housed, all are enclosed with cushion compound (4) and cushion compound (9) in two bead coil peripheries.
