With the growing R&D budget, manufacturers are making a lot of efforts to find new and new ways to reduce the emissions, increase performance and get a minute edge over the competitors. This zeal to get an edge and get past their own expectations is giving us technologies which we never thought would have been possible.
Case-in-point, the newly patented technology from Mercedes-Benz parent company Daimler Motors. Daimler has patented a new technology that wets the tyres when overheated. This water-cooling system will be fitted over the tyre, under the wheel arch and will spray a stream of water to control the tyre temperature.
Wet tyres are usually bad news as they are not good for the grip and can cause wheel spin or slide. But the new patent by Daimler shows that the careful application of water to the car’s tyre could actually improve performance. The whole idea is to prevent the rubber from overheating on an excessively hot day, or during strenuous situations, which can cause tyre failure.
The patent envisioned has a water tank that stores the water to cool tyres that are too hot. There are sensors that will monitor tyre temperature and in case of hot temperature, the system could apply cooling water to the tyres. “Increased driving safety is achieved as the bursting of tires can be prevented by applying the fluid to a tire which is overheated,” promises Daimler’s patent application.
Daimler didn't restrict the patent to cool the tyres only, but also thought of cold weather. The system can spray warm water on the tyres in case of icy or snowy weather and can reduce the ice and snow buildup, or to prevent under inflation in cold weather. The patent states that the sprayer water can be heated with the vehicle’s coolant so that “excess snow or ice deposited on the tire can be removed or warded off.”
While many may argue that Daimler is wasting water instead of formulating a technology to save it, Daimler was thoughtful enough to think it forward. According to the patent, the system is designed in such a way that it will collect rainfall, or snow on the windshield to fill the reservoir. The sensors will also check for rainfall that can cool the car’s tyres too.
We are not sure if Mercedes will borrow this technology from Daimler and apply it to cars, but it is good to see how automakers are working precisely to control every aspect of a car’s performance.
