Automated Range-Change Transmission in a Motor Vehicle and Method for Operation of Same

Abstract

Automated range-change transmission (CT) of a motor vehicle, with a main transmission (HG) with a lay-shaft design, which features a main shaft (WH) and at least one lay shaft (WVG1, WVG2), and with a pre-shift group (GV) drivingly connected upstream on the main transmission (HG), particularly designed as a split group, whereas an input shaft (WGE) of the range-change transmission (CT) is able to be coupled with an internal combustion engine (VM) of a drive unit of the motor vehicle and an output shaft (WGA) of the range-change transmission (CT) with an axle drive (AB) of the motor vehicle, whereas an electric motor (EM) of the drive unit formed as a hybrid drive is able to be coupled at the pre-shift group (GV) through a planetary transmission (PG), whereas the electric motor (EM) is able to be coupled to a first element of the planetary transmission (PG), whereas a second element of the planetary transmission (PG) is able to be coupled with an input shaft of the pre-shift group (GV) and thus the input shaft (WGE) of the range-change transmission (CT), and whereas a third element of the planetary transmission (PG) is able to be coupled with an output shaft of the pre-shift group (GV) and thus an input shaft of the main transmission (HG).
