1. An electric machine for a motor vehicle drive train, the electric machine comprising:
a stator;
a rotor mounted to rotate relative to the stator;
a drive shaft receiving the rotor for conjoint rotation therewith;
a disk element made of sheet metal and also connected for conjoint rotation to the drive shaft arranged in an axial direction of the drive shaft next to the rotor, the disk element having a transmitter contour that is detectable by an eddy current sensor and a coolant guiding contour configured to deflect a coolant stream to the stator and being pressed with an axial prestressing force against an end face of the rotor.
