Ford has developed a patent concept that could change how shock absorbers are designed, potentially making them stronger, lighter and more adaptable without requiring major changes to their internal components. The proposed technology uses an external exoskeleton that could improve cooling, support advanced damping systems and allow automakers to adjust suspension performance across different vehicle models and trims.
Ford’s Shock Absorber Patent Introduces an External Exoskeleton
Modern shock absorbers can incorporate sophisticated technologies, including active and adjustable valving, external bypass systems and additional features designed to improve vehicle performance. These technologies help vehicles such as the F-150 Raptor handle demanding off-road conditions, while performance cars such as the Mustang GTD maintain their grip on the pavement.
Despite these advances, the outer bodies of shock absorbers have generally relied on conventional construction methods, typically using sheet metal formed into a tube. Ford’s patent proposes a different approach by adding an external exoskeleton designed to improve the shock’s performance without requiring a complete redesign of its internal components.
The structure could also accommodate additional equipment needed for specialized vehicle applications, including active damper wiring, control systems, external fluid reservoirs and pressure bypasses.
How the Exoskeleton Could Improve Shock Performance
One potential application involves adding fins to the shock absorber’s external structure. These fins could help dissipate heat, potentially allowing a shock absorber designed with on-road comfort in mind to perform more effectively during demanding off-road use.
The exoskeleton could also increase structural rigidity by reducing deflection under demanding conditions, including high-performance pavement driving and off-road use. According to the patent concept, these improvements could add strength while keeping additional weight to a minimum.
Ford’s proposed design could use several materials, including metal, polymers or carbon fiber. Engineers could adjust the shape of the exoskeleton’s lattice structure to achieve the desired balance of strength, ride quality and weight.
The patent also describes the possibility of using memory metal to make the design responsive to temperature. In one example, the fins could retract when the shock absorber is cold and extend once it reaches operating temperature, potentially improving ride quality during the early stages of a cold-weather drive.
Modular Design Could Support Advanced Suspension Features
Ford’s proposed exoskeleton could make it easier to integrate several suspension technologies into a shared shock absorber design. These include external reservoirs for off-road applications, bypass valves designed for landing jumps and active control valves that allow damping characteristics to be adjusted.
A key element of the concept is that most of the shock absorber or strut’s internal components would remain unchanged. Instead of redesigning the entire unit for different applications, the external structure could be modified to accommodate specific performance requirements.
The patent describes the objective as follows: “alter the performance characteristics of a component shared across different trims and models of vehicles to change vehicle performance without increasing the manufacturing complexity of the vehicle.”
This approach could allow Ford to adapt suspension performance across multiple vehicles and trim levels while retaining much of the same underlying hardware.
What Ford’s Shock Absorber Patent Could Mean for Drivers
If implemented, the concept could simplify the process of developing performance-oriented vehicle models by allowing suspension characteristics to be adjusted without extensive changes to the shock absorber’s internal design.
The modular approach could also make replacement parts easier to find and create opportunities for owners of lower-specification models to upgrade to higher-performing suspension configurations.
Ford’s patent outlines a potential new approach to shock absorber construction, combining a configurable external structure with largely unchanged internal components to improve performance, strength and adaptability without significantly increasing manufacturing complexity.
