Team Profile
This year formula Group T is developing a new car named Eve. She will, like her biblical predecessor, be a pioneer in her genre. So she will be a platform for companies to demonstrate existing core technologies or to test new technologies. In addition to developing new key technologies, we will implement existing technologies from Areion in Eve and try to optimize them.
A great deal of Formula Group T’s designs come together in the electrical drivetrain assembly. It all starts from a 360 Lithium-ion cell accumulator at a voltage of 444V. The accumulator has a carbon fibre fire resistant enclosure and is divided into 10 modules. The accumulator empowers the self assembled motor drive. This lightweight drive controls our 2 motors and weighs less than 15 kg. This assembly is kept cool by a titanium printed cooling plate, which is much lighter than its standard counterpart. The reduction of motorrotation to driving axle rotation is taken care of by our two ‘inner-gear’ gearboxes, these exclusive gear designs keep our drivetrain assembly light and compact.
Like last year with Areion, we would like to keep exploring the benefits of additive manufacturing. Last years 3D-printed body was a rather grotesque approach to really show-off the possibilities of this great technology. This year we challenge the technology in it’s functional purposes by printing little gearboxes in one piece and using experimental patterns on the surfaces of our brake ducts to improve strength. Furthermore, we are cooling the water of our cooling circuit with air that’s being guided by a 3D-printed air duct. Like last year, we are again printing our uprights in titanium, but greatly improving the concepts by applying the lessons we’ve learned from our designs last year.
Our experience from last year and the intensive thesis research from two of our team members will allow for a much more intrinsic implementation of the dynamic behavior of our car. Aside from these virtual models to improve and adjust the dynamic settings of the car, we will also see a great step forward towards agility of the car now that we have reduced our weight with one fourth in comparison to last years car.
