air spring
Definition
Noun: A type of mechanical device that uses confined air (air trapped in a sealed chamber) to absorb the shock or cushion the impact caused by motion or load. It functions as a spring where compressed air provides the elastic force instead of a metal coil or leaf.
Usage
An air spring is used to provide suspension, support a load, or isolate vibration in various vehicles and machinery. * The bus's smooth ride is due to its air spring suspension system. * Heavy machinery often uses air springs to absorb shocks during operation. * The technician replaced the worn air spring on the truck's axle.
Advanced Usage
- "Air spring rate": Refers to the stiffness or how much force is needed to compress the air spring, which can be adjustable by changing the air pressure.
- In engineering contexts, an air spring is a key component in pneumatic suspension systems, where its height and stiffness can be electronically controlled.
Variants and Related Words
- Air bag: A common type of air spring shaped like a bellows or bag, often made of reinforced rubber.
- Pneumatic spring: A more technical synonym for air spring.
- Suspension system: The broader assembly in which air springs are typically used.
Synonyms
- Pneumatic spring
- Air suspension unit
Related Phrases
- To inflate/deflate an air spring: To adjust the pressure and height of the device by adding or releasing air.
- They had to inflate the air springs to level the vehicle after loading.
Noun
-
a mechanical device using confined air to absorb the shock of motion
