Problems solved by technology

Since the sealing ring plays a role of sealing, if the sealing is not good, the brake booster will fail, and the operation will be inconvenient. If the foot brakes are very powerful, the brakes will not be sensitive, which will easily lead to personal injury.
At present, the sealing ring of the spring brake air chamber is produced by hand-moving molded structure mold, the qualified rate of the product is low, the mold is easy to bump, the cost is high, and the auxiliary time is long, resulting in low production efficiency; in addition, the inner and outer circles of the sealing ring are directly facing the breakpoint The sealing effect is poor; the non-working surface of the inner wall of the sealing ring is assembled with grooves, which has poor durability and poor movement sensitivity; and the sealing ring is made of nitrile rubber, which is easy to cause wear and has poor durability, which needs to be improved urgently

Abstract

The invention relates to an air spring sealing ring for a vehicle. The main body structure of the air spring sealing ring is a rubber sheath, a soft metal net is arranged in the rubber sheath, metal reinforcing ribs are arranged inside the soft metal net, and buffering holes are formed in the portion, in the two ends of the soft metal net, of the rubber sheath; a hard support frame is arranged atthe inner circumference of the rubber sheath, sealing protrusions are arranged at sealing openings in the two ends of the rubber sheath, and fastening grooves are formed in the outer circumference ofthe rubber sheath. The prepared sealing ring has various kinds of excellent mechanical performance, the corrosion resistance is excellent, and the quality of a sealing part is greatly improved; an additive 4-pentylbenzeneboronic acid can improve the compatibility among rubber master batches, spider silk protein and amidinourea phosphate improve the strength of acting force among macromolecules, the stability of the net-shaped molecule structure is improved, and then various kinds of mechanical performance of the sealing ring are then effectively improved.

Description

technical field [0001] The invention relates to the technical field of auto parts preparation, in particular to a gas spring sealing ring for automobiles. Background technique [0002] The spring brake air chamber provides braking force for the wheels, including a diaphragm chamber and a spring chamber that are independent of each other, wherein the diaphragm chamber is used for service braking, and the spring chamber is used for emergency braking and parking brake. A sealing ring is arranged in the spring chamber, which is used to prevent the air from leaking from the edge of the spring chamber housing during emergency braking and parking braking of the vehicle. Since the sealing ring plays a role of sealing, if the sealing is not good, the brake booster will fail, and the operation will be inconvenient. If the foot brakes are very powerful, the brakes will not be sensitive, which will easily cause personal injury. At present, the sealing ring of the spring brake air chamb...
