DESIGN AND DEVELOPMENT FOR THE SHORTENING OF THE GEAR ENGAGEMENT IN AN AUTOMOTIVE TRANSMISSION: “SHORT SHIFTER”

In this work the design and development of a device that shortens the engagement distance of the gearbox for the Volkswagen MQ200 gearbox was developed specifically for the VW UP! TSi. This project was initially developed in CAD 3D and after that, all the necessary parts were produced in a machining laboratory in the university campus. All the respective stress analysis were made with the FEA solver of the Autodesk Inventor software as well as all the machining processes. After de development of the parts and manufacture of the prototype, its effectiveness was verified in a test car during seven days which shown that the prototype had a compliance to all the calculation done prior to its production.
