Electric drive axle of a vehicle
An electric drive axle of a vehicle with a parking lock and with at least one electric drive with a drive gear of a drive shaft. The drive gear is coupled via at least one intermediate gear of an intermediate shaft to an output gear of a differential gear unit for driving at least one output shaft. For decoupling the electric drive, at least one claw shift element is associated with the drive shaft and/or with the intermediate shaft in such a way that the claw shift element is arranged upstream of the parking lock in power flow direction from electric drive to differential gear unit.
1. An electric drive axle of a vehicle comprising:
a parking lock;
at least one electric drive;
a drive shaft;
a drive gear of the drive shaft;
an output gear of a differential gear unit for driving at least one output shaft;
at least one intermediate gear of an intermediate shaft that couples the drive gear to the output gear; and
at least one claw shift element that decouples the at least one electric drive is associated with the drive shaft and/or with the intermediate shaft such that the at least one claw shift element is arranged upstream of the parking lock in a power flow direction from electric drive to differential gear unit,
wherein an axially displaceable shifting claw of the at least one claw shift element is arranged coaxial to the drive shaft and can be brought into engagement with a driving toothing of the drive shaft,
wherein a parking lock gear of the parking lock is an idler gear of the drive shaft and arranged to be brought into operative connection with a locking pawl of the parking lock, and wherein the at least one intermediate gear is a fixed gear of the intermediate shaft.
2. The electric drive axle according to claim 1 , wherein
the at least one claw shift element, in a disconnected state, decouples the drive shaft from the intermediate shaft, and
the parking lock, in an engaged state, fixes the intermediate shaft connected to the differential gear unit independent from the at least one claw shift element.
3. The electric drive axle according to claim 1 , wherein the at least one shifting claw element is connected to the drive gear formed as an idler gear.
4. The electric drive axle according to claim 1 , wherein the differential gear unit is constructed as rear axle differential of the vehicle.
5. An electric drive axle of a vehicle comprising:
a parking lock;
at least one electric drive;
a drive shaft;
a drive gear of the drive shaft;
an output gear of a differential gear unit for driving at least one output shaft;
at least one intermediate gear of an intermediate shaft that couples the drive gear to the output gear; and
at least one claw shift element that decouples the at least one electric drive is associated with the drive shaft and/or with the intermediate shaft such that the at least one claw shift element is arranged upstream of the parking lock in a power flow direction from electric drive to differential gear unit,
wherein an axially displaceable shifting claw of the at least one claw shift element is arranged coaxial to the intermediate shaft and is arranged to be brought into engagement with a driving toothing of the intermediate shaft.
6. The electric drive axle according to claim 5 , wherein the at least one shifting claw is connected to the at least one intermediate gear of the intermediate shaft, and wherein the at least one intermediate gear is an idler gear.
7. The electric drive axle according to claim 5 , wherein a parking lock gear of the parking lock is a fixed gear of the intermediate shaft and arranged to be brought into operative connection with a locking pawl of the parking lock.
8. The electric drive axle according to claim 5 , wherein a parking lock gear of the parking lock is formed as fixed gear of the intermediate shaft and can be brought into operative connection with a locking pawl of the parking lock, and in that the at least one intermediate gear is constructed as fixed gear of the intermediate shaft.
9. The electric drive axle according to claim 5 , further comprising
a selector fork in operative connection with the at least one shifting claw, the selector fork is actuatable via an electric motor actuator is provided for axial actuation of the at least one shifting claw.
