Problems solved by technology
[0007] However, these systems have the disadvantage of reducing the efficiency, because on the basis of the series connection of the motors, when one motor is operated as a drive, the second motor also rotates, and the moment of inertia and the magnetic force that arises have to be overcome here

Embodiment Construction
[0035] figure 1 The housing 1 of the hybrid module according to the invention, which is only indicated here, contains a first drive shaft 10 on a common axis of rotation 2, on which the first electric motor 11 is supported in a torsion-proof manner. rotor 12.
[0036]The rotor 22 of the second electric machine 21 engages in a rotationally fixed manner on an output element 30 in the form of an output shaft. The first drive shaft 10 and the output element 30 are positioned in a mutually rotationally symmetrical manner. The second drive shaft 20 is designed to be mechanically connected to an internal combustion engine, which can also be part of a hybrid module, if necessary via a partial clutch.
[0037] The first drive shaft 10 is connected to a common clutch carrier 51 via the first clutch device 13 . Likewise, the output element 30 is connected via the second clutch device 23 to a common clutch carrier 51 . The common clutch carrier 51 is connected in a rotationally fixed ...

The invention relates to a hybrid module for a motor vehicle for coupling an internal combustion engine, and to a drive assembly for a motor vehicle having a hybrid module according to the invention.The hybrid module is designed for coupling an internal combustion engine and comprises a first drive shaft (10), a first electrical machine (11) and a first coupling device (13), as well as a second drive shaft (20) and, associated therewith, a second electrical machine (21), and a second coupling device (23); and further comprises an output element (30), the drive shaft (10, 20) being connectableor connected to the output element (30) by way of a coupling device (13, 23), wherein the two coupling devices (13,23) can be simultaneously actuated by a movement of an actuation element (40) whichis mechanically coupled to the two coupling devices (13, 23). The hybrid module proposed here provides a drive device for a motor vehicle that offers energy-efficient operation in a plurality of different operating modes while requiring a small installation space.
Description
technical field [0001] The invention relates to a motor vehicle hybrid module for connecting an internal combustion engine and a motor vehicle drive comprising an internal combustion engine and a hybrid module according to the invention. Background technique [0002] Electric drives are known and are therefore also used for driving motor vehicles. Here, an electric drive can be provided in combination with the internal combustion engine, for example integrated in a hybrid module, which is designed for connection to the internal combustion engine. [0003] The hybrid module usually contains a coupling for the mechanical coupling of the internal combustion engine, a separating clutch with which torque can be transmitted from the internal combustion engine to the hybrid module and for decoupling the hybrid module from the internal combustion engine, at least one for generating the drive Torque-generating electric motor with rotor, and a further clutch unit, in particular a dua...
