The We, Robot event saw Tesla parade a lineup of futuristic products comprising the Robotaxi, Robovan, and Optimus Robot.
While every product shines in its own way, one thing that still lingers in people’s minds is how the Robovan’s levitating suspension works.
After the colorful event, many stormed Elon Musk, Tesla’s CEO, on X (formerly Twitter), seeking more information about it.
The tech titan responded that the Robovan utilized an automatic load-leveling suspension, which enabled it to have an “unusually low ground clearance.”
So…
What Is the Automatic Load-Leveling Suspension on the Robovan, and How Does It Work?
The Robovan’s automatic load-leveling suspension is based on the hydropneumatic suspension, which allows the suspension to self-level and adjusts the ride height automatically.
This system uses hydraulic fluid, usually pressurized by nitrogen gas acting as a spring, to connect the wheels to the vehicle’s body.
When the vehicle encounters a bump or irregularity on the road, the hydraulic fluid is forced to move, compressing the gas to absorb the shock.
One of the critical advantages of hydropneumatic suspension is its ability to automatically adjust to changing road conditions.
Moreover, it has advanced computerized sensors alongside a control unit that processes sensor data to determine the suitable adjustments to make.
As the load on the vehicle changes, the system can automatically adjust the suspension stiffness to maintain a smooth and constant ride height.
Due to this, along with the Robovan’s low ground clearance, the futuristic van appears to have a cool levitating effect when moving.
Spoiler alert!
Tesla isn’t the first automaker to use this technology.
Automatic Load-Leveling Suspension History
The automatic load-leveling suspension dates back to 1954, when it first debuted on the rear wheels of the Citroën Traction Avant.
A year later, Citroën expanded the feature to cover all four wheels of the 1955 Citroën DS.
From 1965, automakers like Rolls Royce, BMW, and Toyota licensed to use the technology on their vehicles from Citroën.
Apart from cars, the self-leveling suspension nowadays is a common feature on tow trucks, perfect for enhancing handling and stability.
Bose also developed an almost similar setup in 2005, dubbed the electronic suspension system, but it failed to gain traction for being bulky and expensive.
Wrapping Up
The automatic load-leveling suspension on the Tesla Robovan is a marvel of engineering, promising a smoother and more stable ride.
Elon Musk has once again demonstrated his commitment to innovation and pushing the boundaries of automotive technology.
While we may have to wait for its official release, we can all look forward to the day we’ll experience the thrill of riding in it.
