How GUOMAT produce the rubber bellows for air spring

the procedure of the the rubber bellows for air spring。
Technical field:
The invention relates to an air spring composed of an elastomer material with at least two staggered layers composed of reinforcing wires.
Airbag in which the reinforcing threads are inclined at an angle of 40 ° to 80 ° with respect to the circumferential direction of the airbag and are substantially mutually Set in parallel.
Air springs are used as automotive springs in a wide range, especially for elastically supporting wheel axles of trucks and passenger cars,
Has been tested. The significance of air springs in cars is also growing because it is used for walking in motion.
Provides a high level of extreme comfort when organizing.
The air spring has a layer composed of reinforcing wires embedded in parallel and distributed in the rubber, also known as a strength-enhancing layer.
Withstand the force generated by the overpressure in the air spring airbag. Reinforced yarns are usually so-called initial twists for cords, where
Many single fibers (monofilaments) are twisted into a linear shape. Reinforcement yarns are preferably composed of fully synthetic fibers.
Flexural strength, strength, and uniform elongation, such as polyester, polyamide, or aramid, but they can also Composed of metals.
The individual unvulcanized components of the air spring (inner rubber, strength-enhancing layer,The outer rubber and in some cases the wire core) are wound into an air spring blank (molding) and this blank is then vulcanized. in
In this method, a rubberized cord fabric layer is usually used for the strength-enhancing layer.
The cord fabric is composed of many cords which are parallel to each other and located in the warp direction. They use less in the weft direction.
The gauge lines are loosely held together at larger intervals. To improve rubber adhesion (fabric pretreatment)The fabric is impregnated with a suitable rubber compound, such as a neoprene-based compound, after being impregnated.
After cutting, wind it onto the blank according to the desired number of layers, so that the wires of different layers are staggered, and it is best to form a circle 40 ° to 80 ° wire angle. The wire spring angle can be used to influence the bearing capacity and Lateral force.
