Abstract
The present invention relates to an air spring having reinforcement material (1) essentially comprising outer liner (4) which forms the outermost layer of the air springs (1), inner liner (2) which forms the inner layer of the air springs (1) and reinforcement zone (3) which is formed of at least two layers between the inner liner and the outer liner, and including twisted monofilament cords therein.
Description
DESCRIPTION
A AIR SPRING COMPRISING REINFORCEMENT MATERIAL
Field of the Invention
The present invention relates to an air spring having reinforcement material in which twisted monofilament cords are present.
Background of the Invention
The suspension system placed between the vehicle body and the tires is designed to damp the vibrations originated from the structure of the road. The suspension system is a system required in terms of driving comfort and safety. Air springs are one of the most important parts of this system. It is expected to protect the structure of the air springs against the vibrations it take and thus to have high dynamic performance. The air springs are reinforced with polymeric textile material in order to provide the said desired properties. The reinforcement materials that used are manufactured by twisting and weaving the fibers comprised of multifilaments and they are subjected to chemical process. The friction between the filaments in the said reinforcement materials, comprising multifilaments, affects the dynamic properties negatively. With this invention, air springs the dynamic properties of which are improved are provided which are reinforced with textile reinforcement material formed by twisting monofilament structures with each other.
Japanese Patent document no JP2006035750, an application known in the state of the art, discloses a manufacturing method for bellows rubber hose. The bellows which is manufactured has laminated structure and it is comprised of rubber inner pipe, the reinforcing layer on the outer peripheral side thereof and an outer surface rubber layer. The inner pipe is manufactured from vulcanized rubber material and the outer layer is manufactured from unvulcanized rubber material.
Summary of the Invention
The objective of the present invention is to provide an air spring comprising reinforcement material which has low diameter monofilament cords. A further objective of the present invention is to provide an air spring having reinforcement material wherein monofilament structures are used by being twisted.
Another objective of the present invention is to provide an air spring having reinforcement material with high fatigue resistance.
Yet another objective of the present invention is to provide an air spring with increased explosion pressure which has reinforcement material allowing distribution of forces homogenously during explosion.
Detailed Description of the Invention
An air spring having reinforcement material developed to fulfill the objective of the present invention is illustrated in the accompanying figure wherein: Figure 1 is the cross-sectional view of one embodiment of the inventive air spring having reinforcement material.
The components in the figures are assigned reference numerals as follows:
1. An air spring having reinforcement material
2. Inner liner
3. Reinforcement zone
4. Outer liner
The inventive air spring comprising reinforcement material (1) essentially comprises
- an inner liner (2) which is present on the inner side of the air spring (1),
an outer liner (4) which is present on the outer side of the air spring (1), at least two layered reinforcement zone (3) between the outer liner (4) and the inner liner (2). In the inventive air spring, twisted monofilament cord is used in at least one layer of the reinforcement zone (3), and by means of this use air spring with increased dynamic performance and explosion pressure is developed.
At least one of the layers in the reinforcement zone (3) is reinforced with twisted monofilaments comprising polymeric material with 3 to 12 plies and a thickness of at least 475 dtex.
In one embodiment of the invention, the reinforcement zone (3) is comprised of two layers and both layers are reinforced with twisted monofilament cords (Figure 1). The reinforcement material used in the said layers is comprised of
4 plies nylon 6.6 (Ny 66) monofilament structure with total 1900 dtex (475*4).
Life and explosion tests are applied on the air spring having reinforcement material (1) that are manufactured with the abovementioned methods and the air spring comprised of reinforcement zone (3) manufactured completely from nylon 6.6 (Ny 66) multifilament cords. As a result of these tests, it is seen that the air spring (1) with reinforcement zone (3) reinforced with twisted monofilaments give better life and explosion test results than the air spring comprised of reinforcement zone reinforced completely with Ny 66 multifilaments.
Within the scope of these basic concepts, it is possible to develop various embodiments of the inventive air springs comprising reinforcement material (1). The invention cannot be limited to the examples described herein; it is essentially as defined in the claims.
Claims
An air spring (1) essentially comprising
an inner liner (2) which forms the inner layer of the air springs (1),
an outer liner (4) which forms the outer layer of the air springs (1),

and the inner liner (2), and characterized by
reinforcement zone (3) which increases the dynamic life and explosion
pressure by including twisted monofilament cord at least one of its layers.
An air spring having reinforcement material (1) according to claim 1,
characterized by reinforcement zone (3) which is comprised of at least two
layers and wherein the said layers are reinforced with the twisted
monofilament cords.
An air spring having reinforcement material (1) according to any one of the
preceding claims, characterized by reinforcement zone (3) which comprises
twisted monofilaments in z and s direction that follow each other respectively
comprising polymeric material with 3 to 12 plies and a thickness of at least
475 dtex.
An air spring having reinforcement material (1) according to claim 3,
characterized by reinforcement zone (3) wherein the twisted monofilaments
in its structure used for reinforcement are manufactured from Ny 66 polymeric
material.
