Resources Components of Trailer Air Suspension
Trailer Air Suspension Parts include: air spring, shock absorber, control arm, guiding mechanism, thrust rod, and buffer limit block. The air spring is the most critical part of the Trailer Air Suspension Parts. It is an independent pneumatic system consisting of the air spring body, height valve, pressure difference valve, additional air chamber, dust filter, connecting pipes, and air tank.
Trailer Air Suspension Parts Inflation and Deflation System Working Principle
The essence of trailer air suspension height adjustment is the control of the gas mass within the air spring. Since the radial deformation of the air spring is small and the vertical deformation is large, precise control of the air spring's height can be achieved through the inflation and deflation control system. For the Trailer Air Suspension Parts system, since the air springs are in parallel connection, each air spring generally adopts independent inflation and deflation control, thus the work principle can be illustrated by the inflation and deflation system structure of a single-wheel Trailer Air Suspension Part.
Trailer Air Suspension Parts Inflation and Deflation System Working Mode
When the need to raise the vehicle height arises, the switch of the inflating solenoid valve is turned on, and air will flow from the high-pressure tank into the air spring due to the pressure difference. As the mass of the gas inside the air spring increases, the air pressure also increases, pushing the load above the spring upward. When the inflating solenoid valve is turned off, due to inertia, the load above the spring continues to move upward. As the height of the air spring increases, its volume also increases, causing the internal air pressure to gradually decrease, and finally, the load above the spring will remain static at a certain height. To ensure the system operates efficiently and reliably, it is crucial to use advanced trailer spares. These high-quality components are designed to enhance the performance and durability of the air suspension system, providing optimal ride height adjustment and stability.
When the need to lower the vehicle height arises, the switch of the deflating solenoid valve is turned on, and air will flow out from the air spring to the atmosphere through the deflating pipe. As the mass of the gas inside the air spring decreases, the air pressure also decreases, causing the load above the spring to move downward. When the deflating solenoid valve is turned off, the load above the spring continues to move downward due to inertia. As the height of the air spring decreases, its volume also decreases, causing the internal air pressure to increase, and finally, the load above the spring will maintain balance. To ensure the system functions effectively and reliably, it is essential to source components from reputable wholesale trailer parts manufacturers. These manufacturers provide high-quality parts that are designed to meet the specific needs of air suspension systems, ensuring optimal performance and durability.
The air pressure sensor is used to monitor the air pressure in the high-pressure tank. If the air pressure in the high-pressure tank is less than a certain threshold, the air compressor will enter the working mode to replenish the air for the high-pressure tank. The incoming air from the outside into the system air circuit needs to pass through a filter and dryer to keep the air in the entire inflation and deflation system dry and clean.
Trailer Air Suspension Parts Characteristics
Since the stiffness of the air spring is adjustable, the Trailer Air Suspension Parts have almost constant natural frequency. For metal suspension, if the static load of the vehicle increases, the displacement curve of the suspension linearly increases, and the natural frequency of the spring increases accordingly. For air springs, the displacement and load curve is a vertical line, and the frequency and load curve has a very steep slope, proving that the natural frequency of the Trailer Air Suspension Parts is almost constant.
