Making power on the turn
TWO concept tyres that were unveiled by Goodyear at the recent Geneva International Motor Show promise to create electricity and adjust the tyre pressure to suit the road.
The power-making tyre is called the BHO3 and could, according to Goodyear, charge the batteries of electric cars by transforming the heat generated by the rolling tyre into electrical energy. This tyre generates electricity through the action of materials in the tyre that capture and transform the energy created by heat when it flexes as it rolls during normal driving conditions. The materials used would optimise the tyre’s electricity generation capabilities as well as its rolling resistance.
As demand for electric cars grows, this technology has the potential to contribute significantly to the solution of future mobility challenges and could eliminate the vehicle-range anxiety motorists may have with electric cars.
The self-adjusting concept tyre is called the Triple Tube, thanks to three tubes that adjust tyre inflation pressure in response to changing road conditions to ensure optimum grip in all conditions.
The tyre relies on an internal pump that moves air from the main air chamber to the three individual air chambers or tubes. “These concept tyres reimagine the role that tyres may play in the future,” said Joe Zekoski, Goodyear’s senior vice president and chief technical officer. “We envision a future in which our products become more integrated with the vehicle and the consumer, more environmentally friendly and more versatile.”
Although the two tyres are concepts, Zekoski said they represent a vital aspect of Goodyear’s innovation strategy.
