BUGATTI Produces Motor Bracket in Series

Bugatti uses selective laser melting for series production of a motor bracket with integrated water cooling that acts an active heat shield to boast a remarkable reduction in transferred heat. The motor bracket has been installed in all series vehicles since the delivery of the first Bugatti Chiron from the supercar manufacturer’s production facility in Molsheim, France.

The Chiron, like its predecessor, the Veyron, has two separate water-cooling circuits to keep the component and system temperatures at an acceptable level, even under the most extreme environmental and operating conditions. The high-temperature circuit is used to cool the 1,500hp W16 engine of the supercar, while the low-temperature circuit ensures that the intake charge cooling temperature remains suitably low. A bypass flow filter of the NT circuit supplies the console while isolating the electronic components from the temperatures of the transmission oil tank. The primary task of the bracket is to engage the gears while opening and closing the two clutches of the 7-speed dual-clutch transmission while including the control unit. As a result, the temperature at the electric motor and at the control unit of the pump when driving through a demanding handling course can be lowered from 130°C to 90°C, a reduction of 40°C.

The bracket, which was manufactured in the alloy AlSi10Mg on an SLM®280 Twin, was commissioned by SLM Solutions at Rolf Lenk Werkzeugbau GmbH.
