Switching control system for heavy IC engine automatic transmission

摘要

The motor (10) rotating its output shaft (11) and the torque converter (12), acting as the hydraulic drive, with an input shaft (14) for the main drive (16) that increases or decreases the RPM. The RPM is transmitted through output shaft (17) to the differential gear (18). The main drive has (not shown) a drive unit, a planetary drive and several friction couplings and brakes to provide the gear ratios. There is a first and a second coupling for these ratios and a hydraulic servo unit (C-1) for engaging and disengaging the first coupling and a second hydraulic servo unit (C-2) for the second coupling.
