Command device for an automated manual transmission (AMT) with a sleeve tube surrounding the selection rod and method to shift into the associated gear

摘要

The motor vehicle transmission shift control has an internal selector (20) with a longitudinal selection shaft (21) and a transverse finger for ratio changing (22) connected to the shaft. The internal selector has a sleeve (40) around the shaft with a straight longitudinal groove (41) to receive the finger. A control solenoid allows movement of the shaft with respect to the sleeve to rotate the latter.
