Booster Air Suspension Pressure Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer systems with boosters experience instability and directional issues due to increased effective load causing pressure increases in air suspension, leading to decreased load on trailer axles and wheels, which can result in steering or pushing the trailer off course.
Innovation Solution
A trailer system with a booster that includes a connection assembly for pivotal connection to the trailer, an axle assembly with air springs for ride height control, and a pressure regulator to limit the maximum pressure of the fluid supplied to the air springs, thereby maintaining stability and preventing overload conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the booster is in an elevated position relative to the trailer, then the effective load on the booster is increased, but this causes the air suspension pressure to increase excessively, leading to decreased load on trailer axles and instability
Solution Approach 1:
The pressure regulator changes the pressure parameter of the air suspension system by limiting the maximum pressure to a predetermined value. This prevents excessive pressure buildup when the booster is in elevated positions, maintaining stable load distribution between the booster and trailer axles, thereby resolving the instability issue.
2Stability of the object's composition
If the air suspension pressure is increased to compensate for increased effective load, then the ride height is maintained, but the load on trailer axles and wheels is decreased, causing friction loss and directional instability
Solution Approach 1:
The pressure regulator imposes an upper limit on the pressure parameter of the air suspension system. This prevents the pressure from exceeding levels that would transfer excessive load to the booster, thereby maintaining adequate load on trailer axles and wheels to ensure sufficient friction and directional stability.
3Reliability
If the pressure regulator limits the maximum pressure to a predetermined value, then overload conditions are prevented and stability is maintained, but the system cannot fully compensate for elevated booster positions
Solution Approach 1:
The pressure regulator modifies the pressure parameter by establishing a maximum limit that balances two requirements: preventing overload conditions that cause instability, while still allowing sufficient pressure increase to compensate for elevated booster positions. The predetermined pressure value is set to optimize this trade-off.
