1. What Is an External Reservoir in Shock Absorbers?

Un depósito externo in a shock absorber is an additional chamber that holds hidráulico fluid and nitrogen gas separately from the main shock body. This design is commonly found in high-performance and off-road shock absorbers where thermal management and extended travel are critical. It is engineered to offer better rendimiento de amortiguación, cooling efficiencyy longer shock life under extreme conditions.

Key Components of an External Reservoir Shock Absorber

Componente	Función
Main Shock Body	Houses the piston and primary damping fluid
Depósito externo	Contains additional nitrogen gas and/or hydraulic oil
High-Pressure Hose or Tube	Connects the reservoir to the main shock body
Pistón flotante	Separates the gas and oil in the reservoir to prevent cavitation
Compression Adjuster (optional)	Allows tuning of damping characteristics based on terrain or load

Benefits of External Reservoir Shock Absorbers in B2B Applications

• Disipación del calor: Increased fluid volume improves cooling, essential for racing and long-haul applications.
• Reduced Cavitation: The separation of nitrogen gas and oil prevents aeration, ensuring consistent damping.
• Extended Stroke: The remote reservoir allows more room in the main body for piston travel, ideal for high-travel suspension systems.
• Flexibilidad de personalización: Allows for afinación de precisión, lo que los hace ideales para OEMs, specialty vehicle manufacturersy aftermarket performance brands.

For businesses in the automotive supply chain, understanding and offering these shock absorbers can lead to higher value product lines y better customer retention in the performance parts segment.

• More compact and self-contained
• Common in racing and performance applications

Inconvenientes:

• Less flexibility in positioning
• May experience heat transfer from the main body

Depósitos remotos

Remote reservoirs are connected to the shock body via a high-pressure hose, allowing more freedom in placement. This is ideal for custom vehicle builds y applications needing better cooling.

Ventajas:

• Better thermal management (reservoir can be mounted in cooler locations)
• Greater oil volume and stroke length
• Easier access to adjusters in confined chassis setups

Inconvenientes:

• Instalación más compleja
• Requires additional space for hose routing

Característica	Embalse de Piggyback	Depósito remoto
Installation	Easier, compact	More complex, flexible
Eficiencia de refrigeración	Moderado	Alta
Ajustabilidad	Limited by position	Highly accessible
Aplicación	Carreras, coches de alto rendimiento	Off-road, 4×4, RVs
