Abstract
An air spring assembly having pressure relief capability, where the air spring assembly includes a single air volume, or a multi-chamber air volume. When the air spring assembly is operating at a stiffer spring rate in combination with a setting to increase ground clearance, during certain road events, the air spring assembly is compressed, and the pressure in the air spring assembly increases. In order to not exceed the safe mechanical limits of the air spring assembly, the pressure is limited to a maximum value when full compression is achieved. The air spring assembly includes at least one valve, which is opened based on a 'cracking pressure,' which is determined based on the mechanical limits of the air spring assembly. This facilitates the operation of the air spring assembly at settings to increase ground clearance of the vehicle, while allowing for pressure relief when the mechanical limit is reached.
