In the world of automotive suspension systems, shock absorbers are essential components designed to ensure smooth vehicle operation by controlling the impact of road irregularities. These absorbers come in several types, each offering specific advantages based on vehicle requirements. The most common types include two-way acting cylinder shock absorbers, gas-charged shock absorbers, and damping adjustable shock absorbers.
1. Two-Way Acting Cylinder Shock Absorbers
A two-way acting cylinder shock absorber consists of multiple components, including valves, cylinder barrels, pistons, and piston rods. This design helps manage both compression and rebound movements efficiently. Key components include:
Cylinder Barrels: Comprising three sections, these include a dust cover, an oil storage cylinder, and a working cylinder. The oil storage cylinder holds part of the oil, while the working cylinder contains the fluid that facilitates damping.
Piston and Piston Rod: The piston is connected to the piston rod and divides the working cylinder into two chambers. The piston includes extension valves and flow valves, crucial for regulating fluid movement and generating damping forces.
In the operation of a two-way shock absorber, when the vehicle’s frame and axle move relative to each other, the piston moves inside the cylinder barrel. Oil circulates between the two chambers through valve openings, generating a damping force through friction and fluid resistance. This process transforms mechanical energy from vibrations into heat, which is then absorbed by the oil and dissipated into the atmosphere.
The damping force generated in these systems depends on several factors, including:
The viscosity of the oil,
The spring rate of the valve,
The cross-sectional area of the oil channels.
This type of shock absorber provides a stable ride by controlling both compression and rebound movements, making it ideal for general automotive applications.
2. Gas-Charged Shock Absorbers
Gas-charged shock absorbers, including those from Saijian, feature a unique design with a floating piston and a high-pressure nitrogen chamber. These shock absorbers separate the oil and gas using a large section O-ring, which prevents foam formation during operation. The system includes:
Working Pistons: Responsible for moving within the oil to create an oil pressure difference, which opens or closes the compression and extension valves.
Floating Pistons: These move upward and downward to compensate for changes in cylinder barrel volume due to the presence of piston rods.
As the wheel moves relative to the frame, the working piston reciprocates, causing oil to flow through the valves, which generates the damping force. The gas chamber (filled with nitrogen) maintains consistent pressure, ensuring smooth suspension operation across various driving conditions. This type of shock absorber is commonly found in high-performance and off-road vehicles due to its superior ability to handle dynamic load variations.
3. Damping Adjustable Shock Absorbers
Damping adjustable shock absorbers are designed to offer flexibility in adjusting the damping force based on specific driving needs. They typically include a hollow connecting rod and a plunger system, which are linked to a diaphragm and spring. As the vehicle’s load changes, the air pressure in the air spring increases or decreases, influencing the damping force.
Key features include:
Adjustable Orifices: As the plunger moves, the orifice’s cross-sectional area changes, either restricting or allowing more fluid to pass through. This change in flow resistance adjusts the damping characteristics of the shock absorber.
Spring and Diaphragm: The spring helps regulate pressure changes, while the diaphragm controls the movement of the plunger, ensuring precise damping control.
This type of shock absorber is ideal for vehicles that require variable damping capabilities, allowing drivers to adjust the suspension stiffness based on road conditions or driving preferences.
