Patent ID: 10071622

Abstract:
An automated range-change transmission (CT) of a motor vehicle, has a main transmission (HG) with a lay-shaft design, which features a main shaft (WH) and at least one lay shaft (WVG1, WVG2), and a pre-shift group (GV) drivingly connected upstream on the main transmission (HG). 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. An output shaft (WGA) of the range-change transmission (CT) is coupled with an axle drive (AB) of the motor vehicle. An electric motor (EM) of the drive unit is able to be coupled at the pre-shift group (GV) through a planetary transmission (PG), whereas the electric motor (EM) is coupled to a first element of the planetary transmission (PG), a second element of the planetary transmission (PG) is coupled with an input shaft of the pre-shift group (GV), and a third element of the planetary transmission (PG) is coupled with an output shaft of the pre-shift group (GV).
