Description

Heat shield and air spring

Technical Field

The utility model relates to a vapour accessory field of making, specifically speaking relates to separate heat exchanger and air spring.

Background

The air spring is a spring which is filled with compressed air in a telescopic closed container and utilizes the elastic action of the air. Commonly known as air bags, air bag type cylinders, leather bag cylinders and the like. The air spring is formed by filling compressed air into a sealed container and realizing the elastic action by utilizing the compressibility of the air. The air spring has ideal nonlinear elastic characteristics, after the height adjusting device is additionally arranged, the height of a vehicle body does not change along with the increase and decrease of the load, the rigidity of the spring can be designed to be lower, and the riding comfort is good. However, the air spring suspension has a complicated structure and high manufacturing cost.

Air springs are widely used in self-adjusting air suspensions for commercial vehicles, buses, rail vehicles, machinery equipment and building foundations. The working principle of the air spring is that inert gas or oil-gas mixture is filled in a closed pressure cylinder, so that the pressure in a cavity is several times or dozens of times higher than the atmospheric pressure, and the motion of a piston rod is realized by utilizing the pressure difference generated by the fact that the cross section area of the piston rod is smaller than that of the piston. Due to the fundamental difference in principle, the gas spring has very remarkable advantages compared with the common spring: the speed is relatively slow, the dynamic force change is not large (generally within 1: 1.2), and the control is easy; the disadvantages are that the volume is relatively small without a helical spring, the cost is high and the service life is relatively short.

The existing cab air spring shock absorber on the market is configured without a heat shield, hot air, hot water and the like generated in the running of a vehicle can heat the pipelines through pipelines, the heated pipelines can be contacted or too close to an air bag of the air spring due to vibration generated in the running of the vehicle, the air bag is usually made of natural rubber materials and can bear the highest temperature of 80 ℃, but the highest temperature of the pipelines is higher than 80 ℃, so that if the pipelines are too close to or contacted with the air bag, the air bag is overheated, deformed, damaged and cracked, and the service life of the air bag is greatly influenced.

Therefore, the utility model provides a separate heat exchanger and air spring.
