Drivetrain

Abstract

A drivetrain comprises a differential gear with a first input shaft (5) for a drive motor (4), a second input shaft (10) for a differential drive (16), and an output shaft (2) for a driven machine (1). The differential gear further comprises two planetary gear stages (7, 8) whose planet gears (11, 12', 12'') are mounted in a common planet carrier (9, 32). The first input shaft (5) is connected to a first sun gear (6) of the first planetary gear stage (7), and the output shaft (2) is connected to a second sun gear (15) of the second planetary gear stage (8). The first planetary gear stage (7) has inner planet gears (11) and outer planet gears (12'). The inner planet gears (11) and the outer planet gears (12') are mounted on the planet carrier (9, 32).The outer planet gears (12'') of the second planetary stage (8) are rotationally fixed to the outer planet gears (12') of the first planetary stage (7) and the inner planet gears (11) are engaged with the outer planet gears (12') of the first planetary stage (7) and with the first sun gear (6).
