1970 - A shift simplification for heavy truck transmissions: the PORSCHE compressed air switching aid.

A small device that meets all the requirements for a smooth and cost-effective gearbox.

Not only supercar. Porsche engineering have been developing patents for a great variety of automotive and industrial application for more than a century.

Here below the original copies of a ingenious tool which helps the track drivers to shift in a easier and cost effective way, by means of a pneumatic aid.

Nothing to be surprised, considering the experience gathered by Porsche with its famed synchromesh ... not to mention the Sportomatic for its sports car or the later Tiptronic, PDK and so on.
