Description

Technical Field

[0001] The invention relates to the technical field of airbag type independent suspension, and in particular to an airbag type new energy heavy truck front independent suspension. Background Art

[0002] The airbag-type new energy heavy truck front independent suspension is a vehicle suspension system that uses airbags as shock-absorbing elements. The following are some of the characteristics of this suspension system:

[0003] Load-carrying capacity: Airbag suspension systems usually have a strong load-carrying capacity;

[0004] Application: Airbag suspension is more common in buses and light trucks. Although the travel is short, it provides good comfort.

[0005] The airbag suspension system can effectively absorb vibrations, improve ride comfort, and in some cases, such as off-road environments, can provide better passability and adaptability.

[0006] When using the front independent suspension of an airbag-type new energy heavy truck, you need to pay attention to the impact of high temperature. Since the airbag is made of rubber, the following situations may occur in the airbag under high temperature environment:

[0007] Thermal aging: High temperature will intensify the oxidation reaction process of rubber, causing changes in the molecular chains inside the rubber airbag, such as degradation or structuring, thereby accelerating the aging process;

[0008] Changes in material properties: Airbags are usually made of rubber or other elastic materials, which will undergo physical and chemical changes at high temperatures;

[0009] Accelerated oxidation reaction: Under high temperature environment, the reaction rate between oxygen and airbag materials is accelerated, leading to oxidation aging. This oxidation reaction will cause cracking and hardening on the surface of the airbag, reducing its service life;

[0010] Increased moisture permeability: At high temperatures, moisture permeability also increases, further accelerating the aging process;

[0011] Therefore, during the use of the airbag, it is necessary to avoid high temperature environment as much as possible to extend the service life of the airbag and ensure the stability of its performance.

When the shock absorber 5 is expanding and contracting, the shock absorber 5 will drive the assembly frame 801 on the heat dissipation component 8 to move up and down synchronously. At this time, the fan blade plate 803 located inside the assembly frame 801 and connected to one end of the support rod 802 will swing up and down due to the expansion and contraction of the shock absorber 5, so that the fan blade plate 803 will form a fan effect, thereby generating upward and downward airflow movement. At this time, the rising airflow generated by the fan blade plate 803 will blow toward the airbag shock absorbing mechanism 7, thereby realizing cooling the surface of the airbag shock absorbing mechanism 7, thereby reducing the aging speed of the airbag shock absorbing mechanism 7 and ensuring the stability of the use of the airbag shock absorbing mechanism 7. When the heavy truck stops running, the fan blade plate 803 will be limited in position by the two retaining springs 804, and at this time, the fan blade plate 803 is in a parallel state.
