Embodiment Construction

[0029] figure 1 A drive train 100 is shown, for example a drive train in a motor vehicle. Drivetrain 100 includes internal combustion engine 105 , hybrid module 110 , optional transmission 115 , and drive wheels 120 . Preferably, the transmission 115 is a semi-automatic or fully automatic transmission (such as a dual clutch transmission), a stepped automatic transmission or a transmission with a continuously variable transmission ratio (Continuous Variable Transmission, CVT). Torsional vibration dampers or torsional vibration dampers 125 can be arranged at various points of drive train 100 , in particular between hybrid module 110 and transmission 115 or between transmission 115 and drive wheels 120 .

[0030] Hybrid module 110 includes an input side 130 for connection to internal combustion engine 105 and an output side 135 for connection to the part of drive train 100 leading to drive wheels 120 . An electric motor 140 having a stator 145 and a rotor 150 is provided as a d...

Abstract

The invention relates to a hybrid module for a motor vehicle power train, comprising an input side for connecting to an internal combustion engine, an output side for connecting to a drive wheel, an electric drive motor comprising a stator and a rotor and a torque transfer device is arranged between the rotor and the output side. Said transfer device is designed to reduce rotational irregularity.

Description

technical field [0001] The invention relates to a hybrid module for a drive train in a motor vehicle. In particular, the invention relates to the reduction of rotational inhomogeneities in hybrid modules. Background technique [0002] In a drive train, for example of a motor vehicle, two different drive motors are provided. The first drive motor usually includes an internal combustion engine, while the second drive motor is designed as an electric motor. In one embodiment, the rotor of the electric motor is permanently connected to an input shaft of a transmission which acts on drive wheels of the motor vehicle. General techniques for reducing rotational non-uniformity due to rotational motion provided by an internal combustion engine generally do not consider electric motors. The form of the vibration behavior of the drive train can be significantly changed by the electric motor. As a result, unfavorable vibration amplitudes can result, in particular at the input of the...
