Understanding the Suspension Mechanism of Concept Cars: Hinges and Cylinders

Concept cars often push the boundaries of automotive design and technology, showcasing innovative ideas and possibilities. One common feature in concept car suspensions is the hinge mechanism, which differs from traditional spring-loaded setups. In this article, we will explore the hinge-based suspension systems, their benefits, and dissections of some real-world examples.

The Role of Hinges in Suspensions

When you see a cylindrical shaped item or a hinge-like structure in a concept car's suspension, it is not a spring but often a hinge. Hinge mechanisms in concept car suspensions function similarly to door hinges, allowing the suspension arm to pivot and move. Instead of relying on a traditional spring to absorb impacts and maintain ride comfort, these systems often use hydraulic or pneumatic shock absorbers combined with hinge mechanisms to achieve their unique design and performance goals.

Practical Applications in Three-Wheeled Vehicles

Hinge-based suspensions are not as uncommon as one might think. Similar setups are evident in three-wheeled vehicles such as tuk-tuks in India and South-East Asia. These vehicles often use a more rugged and flexible suspension system that can handle the rough terrain and occasional bumpy rides. The cylinder-like structures in concept car suspensions operate on a similar principle, providing a point of rotation that allows the suspension arms to move through the tire travel.

Design vs. Practicality

While the hinge mechanism in concept car suspensions can offer unique design flair, it may not always be the most practical solution. Some observers suggest that such systems, like the ones described in the pictures, resemble more the hand-drawn ideas of 14-year-old gamers rather than serious engineering prototypes. The kinematics of these setups are often impractical and challenging to translate into functional vehicles. The designers and engineers working on these concepts focus more on aesthetics and innovation rather than perfecting a fully functional and practical suspension system.

Spring and Shock Absorber Integrations

References to a shock absorber assembly in these images suggest that while the hinge may not act as a spring, a spring or a similar energy-absorbing component is usually integrated elsewhere in the system. For instance, in the rear wheel suspension setup, a visible shock absorber assembly might contain a spring that absorbs the impact and maintains ride stability. This integration of shock absorbers with hinge mechanisms can offer a balanced approach to achieving both design and performance objectives.

Conclusion

The hinge mechanism in concept car suspensions adds a layer of complexity and visual appeal to automotive design. While it may not always align with practical road conditions, its use in concept cars demonstrates the endless possibilities in engineering and automotive design. Understanding these unique suspension mechanisms not only deepens our appreciation for design but also sheds light on the balance between innovation and practicality in the automotive industry.
