Th!nk, the electric car from Norway, has started a relationship with Oerlikon Graziano, who makes gearboxes. So, they designed a special gearbox, the only one at this time made specially for electric vehicles. With this gearbox, th!nk wil have the most efficient transmission system, would not waste energy on useless rpm, and run quietly. It can go up to 180km and have a maximum speed of more than 110km/h (>68 mph).
Richard Canny, Th!nk CEO, says: “We opted for Oerlikon Graziano because of its superior technical expertise as a development partner and system supplier”. Th!nk is not the only customer Oerlikon Graziano has. Zytek Automotive LTD wants to apply their 70kW electric motor’s output to a gearbox designed by them. Ford also has plans for a partnership with the gearbox manufacturer.
So, what can’t for the moment be gotten from battery technology, can partially be obtained from other components, like the gearbox, aerodynamic shape and tire rolling resistance. Car technology evolves – it’s good to know where it’s heading to.
All gear boxes consume energy. A more efficient system would be a reostat like found in your windshild wipers. But then we will still be stuck with a 12% efficient global warming golf cart no matter how you try to improve it. Oil is and will forever be our only sorce of portable fuel for cars and planes. Once depleted we may need the bicycle.
