Drive device with at least one electric engine
View Patent ↗A drive device having at least one electric machine, a gearbox, a differential which can be driven by the electric machine by means of the gearbox, at least one torque-fixed first operative connection between a first drive shaft of the electric machine and the gearbox.
1. A drive device, comprising:
a first drive shaft;
at least one electric motor connected to a first gear via said first drive shaft;
a manual transmission connected to said first drive shaft via said first gear and via an engageable connection, said engageable connection arranged between said first gear and a second gear;
a differential which can be driven by the electric engine via the manual transmission;
a clutch operatively arranged to connect said first gear with said second gear to establish said engageable connection;
a brake operatively arranged to fix said second gear; and,
an actuator drive operatively arranged to engage said clutch or said brake.
2. The drive device recited in claim 1 , further comprising a second drive shaft arranged a distance from said first drive shaft.
3. The drive device recited in claim 1 , in which the actuator drive comprises another electric engine.
4. The drive device recited in claim 1 , in which the manual transmission represents a planetary drive with at least one planetary gear.
5. The drive device recited in claim 4 , wherein said first gear is of a first planetary drive of the manual transmission.
6. The drive device recited in claim 5 , wherein said clutch comprises a clutch member operatively arranged to engage and disengage two connection shafts of the first planetary drive.
7. The drive device recited in claim 5 , comprising a second planetary drive operatively arranged to connect the first planetary drive and the differential.
8. The drive device recited in claim 1 , in which the differential represents a planetary differential with at least a third planetary drive.
9. The drive device recited in claim 1 , comprising a transmission connection between the second drive shaft and a speed transformer, by which the speed transformer can be driven.
10. A drive device, comprising:
a drive shaft;
a first planetary gear rotatably secured to said drive shaft via a non-rotatable connection, said first planetary gear having a first carrier;
a second planetary gear non-rotatably connected to a housing and said first carrier;
a differential operatively arranged to transmit torque from said second planetary gear to an output means;
a clutch secured to the drive shaft and operatively arranged to lock said first planetary gear;
an electric motor operatively arranged to drive said drive shaft; and,
an actuator operatively arranged to actuate said clutch.
11. A drive device, comprising:
an input means;
an output means;
a clutch;
a first planetary gear comprising a first carrier; and,
a second planetary gear comprising a second carrier;
wherein when said clutch is engaged a first torque path flows from said input means to said first planetary gear in a 1:1 gear ratio and then to the second planetary gear via said first carrier and then to the output means via said second carrier; and,
wherein when said clutch is disengaged a second torque path flows from said input means to said first planetary gear in a second gear ratio and then to the second planetary gear via said first carrier and then to the output means via said second carrier.
