A TRANSMISSION AND SHIFT METHOD

摘要

Transmission in which the mechanical gear shift arrangement are replaced by electro-hydraulic operated shift mechanisms have to be able to be neutralised positively to ensure a proper operation. The disclosure shows an arrangement and method to determine the position of the shift rail so a shift can be made only if the conditions are right. To prevent engagement of two shift members at the same time and consequent damage in case of electronic failure, mechanical safety features such as detents are included.
