Abstract

Number of Manual Transmission (MT) is expected to grow as the car market expends in the development countries. Other aspects, localization of MT production and DCT/A-MT expansion are required to be considered as a part of MT future. Technologies adopted to MT have been changing as the requirements from the car changing continuously, especially those to counteract more powerful engine and to improve gear change quality. Some of the new technologies, MT architecture, way of input load assessment, gear grinding method, synchronizer, adopted to the up-to-date MT are presented in the paper.
