Electrical axle
An electrical axle comprising an electrical motor selectively connected to a differential via a reduction gear and a planetary gear set, the planetary gear set having one input and two outputs, the electrical axle further comprises a gear shift mechanism configured to selectively connect a differential housing to one of the outputs.
1. An electrical axle, comprising an electrical motor which is selectively connected to a differential via a reduction gear and a planetary gear set, said planetary gear set having one input and two outputs, wherein the electrical axle further comprises a gear shift mechanism configured to selectively connect a differential housing to one of said outputs, wherein the electrical motor is driving a sun gear of the planetary gear set, which sun gear forms the input of the planetary gear set, and wherein the outputs are a planet carrier and the sun gear of the planetary gear set.
2. The electrical axle according to claim 1 , wherein the gear shift mechanism is further configured to be selectively disconnected from both outputs.
3. The electrical axle according to claim 1 , wherein the electrical motor is arranged non-coaxially with drive shafts being connected to said differential.
4. The electrical axle according to claim 1 , wherein the sun gear forms a hollow shaft surrounding a drive shaft.
5. The electrical axle according to claim 1 , wherein the speed reduction of the reduction gear is approximately 12-14:1.
6. The electrical axle according to claim 1 , wherein the speed reduction between the sun gear and the planet carrier is approximately 3-4:1.
7. The electrical axle according to claim 1 , wherein the gear shift mechanism is a dog clutch.
8. A vehicle, comprising an electrical axle comprising an electrical motor which is selectively connected to a differential via a reduction gear and a planetary gear set, said planetary gear set having one input and two outputs, wherein the electrical axle further comprises a gear shift mechanism configured to selectively connect a differential housing to one of said outputs, wherein the electrical motor is driving a sun gear of the planetary gear set, which sun gear forms the input of the planetary gear set, and wherein the outputs are a planet carrier and the sun gear of the planetary gear set.
