Automotive shock absorbers, as key components of suspension systems, have various forms and functions, providing crucial support for driving comfort. Let's delve into the types of shock absorbers classified from different dimensions:
1. Hydraulic and Inflatable: The Source of Shock Absorption Force
Hydraulic shock absorbers: As a mainstream choice, they use the damping force of oil to absorb road vibrations. When the vehicle body vibrates, the piston moves inside the cylinder, creating resistance to vibration by controlling the flow of oil.
Inflatable shock absorber: a newcomer after the 1960s, with a floating piston and nitrogen gas seal, the working piston adjusts the oil pressure through a valve that changes the cross-sectional area of the channel, achieving rapid vibration attenuation.
2. Structural classification: Comparison between single tube and double tube
Double tube shock absorber: Through the cooperation of the inner and outer tubes, the piston's entry and exit allow the oil to flow between two spaces, ensuring the continuity of the shock absorption effect. Four valve components, such as flow valves and compensating valves, ensure the precise operation of this complex structure.
Single tube shock absorber: The design is more streamlined, requiring only a floating piston and a nitrogen chamber. The movement of the piston directly affects the oil pressure, achieving efficient transmission of shock absorption effect.
The diversity of shock absorbers not only meets the needs of different vehicles, but also reflects engineers' deep understanding and technological innovation of driving experience. Their existence makes every journey smoother, ensuring a comfortable experience for both drivers and passengers
