To measure the efficiency of the car's drivetrain, Green Team Twente has built a bespoke test rig based on the TorqSense torque sensor made by Sensor Technology Ltd of Banbury in the UK.
Green Team Twente is committed to developing the most efficient hydrogen car in the world. The multidisciplinary team consists of staff and students from two universities in the Netherlands, Saxion Hogeschool and the University of Twente. It develops a new hydrogen car every year, building on the design of the previous year.
At the start of this academic year, there was an important choice for the mechanical engineers in the team to make; could they gain more efficiency by further optimising the current drivetrain of the car or should they move to another technique? The drivetrain consists of four DC motors that power the rear left wheel via a Cardan shaft and custom-made gearbox.
