Team Details

Racetech Racing Team TU Bergakademie Freiberg e.V.

Team Description

Per May 2010, the Racetech Racing Team introduced its fourth racecar to the public. 45 students were involved in the design of the RT04. The overall design strategy was to gain stiffness and power while saving weight. All parts within the suspension assembly where designed with the help of CAE-tools, while greater focus was laid on kinematic issues. The body shell is made of magnesium sheets as a unique and reasonable feature within the Formula Student. Intense simulation and validation activities around the engine unit lead to increased power. The drivetrain is based on self designed tripod joint shafts, using electron beam technology for joining and hardening. To ease up the handling of all electronic devices, they were modularized through the help of CAN Bus technology. A Live-Telemetry System is installed and helps to survey the cars performance. We are looking forward to a great competition and discussing our solutions with judges and competing teams.

Info

The Racetech Racing Team proudly presents its new racing car RTo5. After four increasingly succeeding racecars since 2005, great expectations laid on the new very young team of the race smithy from Freiberg. The season began with 38 students and promising ambitions. We modified the camshaft and developed a new gearbox that perfectly matches the requirements of Formula Student competitions. Furthermore we are racing with one of the lightest carbon fibre rims of the FS worldwide. Another great development was the simulation of the wiring harness in a 3D CAD system allowing the manufacturing of the harness independently to the racecar. Our drive train is based on self designed tripod joint shafts joined and hardened by an electron beam technology. Completed by our unique silvery shining body shell made of magnesium sheets we are entering the competition with a weight reduction of almost 20 kg. Our team is looking forward to compete at this year’s FS Germany with the new racecar RTo5.

Info

RT03 is the latest achievement of the Racetech Racing Team TU Bergakademie Freiberg – our new racecar surrounded by the one and only magnesium body shell worldwide. The actual development status is a merit of 3 teams’ efforts with lots of challenges: At the beginning there was only a union of students to build the idea of a driving-ready racer. After 1 year of hard work we managed to push our roadworthy RT01 in start position at FSG2007. Next step was to evaluate the experiences of the first racecar and to improve the master plan. The result became the RT02, our second bolide, with which we did a really better job at FSG2008 in many aspects. Additionally the award for the best prepared car for scrutineering approved the good manufacturing of all its parts. Today our team counts 45 motivated students. Our main focus lies more and more on the intelligent use of a materials mixture consisting of high end aluminium- and steel-alloys besides composite materials and especially magnesium.

Info

At beginning there were a union of students to build the idea to regulate a driving-ready racer. So the Racetech Racing Team TU Freiberg e.V. was founded on 20th of April, 2005 with the discharge of our statute. Since then we can exist regardless of the university and operate independently.After 1 year of hard work we attended to Formula Student Germany 2007. Although our RT01 did not go on overtaking lane at first time we were very proud of our achievement building an exceeding race car.Today our team passes approximately 34 motivated students, which study vehicle construction, mechanical engineering, economic engineering, geotechnics and many other subjects. Meanwhile with our many-sided knowledge we have improved and developed our RT02. The team’s main focus is lying on high end materials and its production technologies such as magnesium-, aluminium- and steel- castings besides composite materials.We would like to thank our University, our Sponsors but especially our Families.
