Hybrid drive having an automated conventional gearbox

Abstract

The invention relates to a hybrid drive having an automated conventional gearbox, for example for a motor vehicle, having an internal combustion engine (VM) which has a drive connection to at least a first transmission input shaft (W1), having an electric drive which has at least one electric machine (EM1) which has a drive connection to a second transmission input shaft (W3; W3′), having at least one layshaft (W4), having freely moving wheels and fixed wheels (z11-z17, z21-z29, zR3) which are arranged in a plurality of wheel set planes (Z1-Z7), having a plurality of gear shift devices (S1-S4), and having a transmission output shaft (W2). In order to permit a high degree of variability in terms of a wheel set concept as well as the distribution and the number of electrical and internal-combustion-engine gearspeeds, to keep the expenditure on design and the costs low and to ensure efficient and comfortable operation, there is provision that the two transmission input shafts (W1, W3; W1, W3′) are arranged coaxially with respect to one another, and in that in one of its shifted positions a gear shift device (S1) connects the two transmission input shafts (W1, W3; W1, W3′) to one another effectively in terms of drive, and in another shifted position shifts a gearspeed.
