Description
Technical Field
The utility model relates to a take air spring car bumper shock absorber suspension assembly.
Background
The damping effect of the damper suspension assembly is good and bad, and the riding comfort of the car is directly influenced. The car shock absorber suspension assembly with the gas spring can change the amount of gas in the air bag through the inflation and deflation of the pressure maintaining air nozzle to adjust the hardness of shock absorption and the height of a car body, so that corresponding changes can be made according to different road conditions, for example, when a user drives the car to pass through a rugged road surface, a computer arranged in a pit can enable the air bag to inflate and harden to play a better supporting role; on the contrary, if the computer is driven to an upward slope, the computer can deflate the air bag to be soft; in addition, when the automobile runs at a high speed, the computer can enable the air bag to deflate and soften to control the automobile body to reduce, wind resistance above the automobile body is reduced, and the automobile is more stable, so that the comfort and operability of the automobile are better due to the use of the car shock absorber suspension assembly with the air spring, and the trafficability of different road conditions is stronger. However, in the suspension assembly of the car shock absorber with the gas spring in the prior art, as the radial stress of the air bag is larger when the air bag is inflated, and the outside of the air bag is not protected completely, the service life is influenced, and the damping effect is also influenced. In addition, the assembly of the suspension assembly of the gas spring shock absorber is inconvenient, and the sealing of the air bag cannot be better ensured.
Disclosure of Invention
In view of the deficiencies of the prior art, the utility model aims at providing a take gas spring car shock absorber suspension assembly who has gasbag protection design, the shock attenuation is effectual, long service life, the assembly of being convenient for and better guarantee that the gasbag is sealed.
The utility model adopts the following technical proposal to complete:
take gas spring car bumper shock absorber suspension assembly, the gas spring bumper shock absorber and the damping bumper shock absorber combination that set up from top to bottom form its characterized in that: the air spring shock absorber comprises a vibration isolation mounting seat and a leather bag, the vibration isolation mounting seat is connected to the top end of a piston rod of the damping shock absorber, the upper end of the leather bag is tightly buckled with the vibration isolation mounting seat through an upper pressing ring, the lower end of the leather bag is tightly buckled with an iron sleeve through a lower pressing ring, the iron sleeve is arranged outside a cylinder body of the damping shock absorber and fixedly connected with the cylinder body, an aluminum sleeve is arranged outside the leather bag, and the leather bag is tightly buckled with the aluminum sleeve through a middle pressing ring.
According to the suspension assembly with the gas spring car shock absorber, the aluminum sleeve is arranged outside the leather bag, and the leather bag is tightly buckled with the aluminum sleeve through the middle pressure ring, so that the air bag is protected externally, and due to the fact that the air bag is limited by the aluminum sleeve, the radial direction of the air bag is basically very small in stress when the air bag is inflated, extra stretching of the air bag cannot be caused, the service life is prolonged, and the damping effect is also improved.
