Definitions
- the transmission lubricating oil already present in the housing is used to cool the electrical components provided in a housing.
- a mechanically driven oil pump transfers the transmission oil from the oil sump of the housing to the components to be cooled.
- two drive paths can be provided for driving the oil pump, each of which is assigned a freewheel, so that the rotation of the pump shaft in the same direction of rotation is made possible regardless of the direction of rotation of the drive shaft.
- an electric drive for a vehicle with at least one electric machine in a housing with a rotor shaft as the drive shaft wherein the drive shaft or the rotor shaft can be coupled to an intermediate shaft via at least one spur gear, the intermediate shaft having an output differential for driving output shafts is coupled.
- at least one mechanically driven oil pump is provided for the oil supply, with a pump shaft of the oil pump regardless of the direction of rotation of the intermediate shaft in the same direction of rotation via a first drive path with at least one first freewheel and via a second drive path at least one second freewheel and with at least one differential gear can be driven and wherein at least the first freewheel and the second freewheel and the differential gear are arranged radially inside the intermediate shaft designed as a hollow shaft to save space.
- a particularly structurally simple and space-saving embodiment of the present invention provides that, in order to implement the first drive path, the first freewheel is connected on the one hand to the pump shaft and, on the other hand, to the intermediate shaft, and that in order to implement the second drive path, the intermediate shaft is connected to the pump shaft via the differential gear and the differential gear is connected on the housing side via the second freewheel.
- the first torque transmission path or the first drive path comprises only the first freewheel, since the intermediate shaft is more or less directly coupled to the pump shaft via the first freewheel and thus enables a drive when the first freewheel is locked.
- the planetary gear carrier is designed in the form of a sleeve or cup, the bearing bolts of the planetary gears being supported or fastened on one end face. Due to the sleeve-shaped or cup-shaped planetary gear carrier, this can be arranged coaxially to the second freewheel, the second free-wheel being received radially inside the sleeve-shaped or cup-shaped planetary gear carrier in a space-saving manner.
- the intermediate shaft designed as a hollow shaft, preferably has a circumferential toothing as a ring gear toothing on its inner circumference.
- the ring gear is quasi gebil det on the inner circumference of the intermediate shaft and is thus z. B. made in one piece with the intermediate shaft.
- Optimal operation of the electric drive with sufficient oil supply is achieved in that the first direction of rotation of the intermediate shaft corresponds to the forward drive of the electric drive and the second direction of rotation of the intermediate shaft corresponds to the reverse drive.
- the same cooling performance or the same is achieved in the drive according to the invention through the use of the planetary gear due to the translation of the planetary gear Pump performance as realized when driving forward.
- Another aspect of the present invention is to claim a vehicle with the above-described electric drive. This results in the already described and other advantages.
- a particularly advantageous embodiment is to provide the electric drive as an axle drive in the vehicle.
- the first freewheel 9 and the second freewheel 10 and the differential gear 25 are arranged radially inside the intermediate shaft 3 designed as a hollow shaft in order to achieve a particularly space-saving arrangement.
- the second drive path has the planetary gear and the second freewheel 10, a sun gear 17 of the planetary gear being connected directly or indirectly to the pump shaft 8 in a rotationally fixed manner.
- a ring gear 18 of the planetary gear is formed by the inner surface of the inter mediate shaft 3 by a corresponding toothing is provided on the inner circumference of the inter mediate shaft.
- the ring gear is rotatably connected to the intermediate shaft 3 a related party.
- the ring gear 18 and the sun gear 17 are connected to each other via planet gears 19 for torque transmission or are in engagement with each other.
- the planet gears 19 are supported by the planet gear carrier 20.
