Abstract
A drive device for a motor vehicle, includes a differential gearing and a torque vectoring unit having an electric machine, wherein the differential gearing has a first and a second planet set, which are rotatably supported on a common planet carrier, wherein the first planet set meshes at least with a first sun, the second planet set meshes at least with a second sun, and the two planet sets at least mesh with each other in pairs, and wherein at least the second sun is connected to the torque vectoring unit in order to redistribute the torque between the first and the second suns.
Claims18
A drive device for a motor vehicle comprising:
- a differential gear;
- and
- a torque vectoring unit having an electric machine, the differential gear having a first planet set and a second planet set, the first planet set and the second planet set being rotatably mounted on a common planet carrier, the first planet set meshing at least with a first sun, the second planet set meshing at least with a second sun, the first planet set and the second planet set meshing with one another at least in pairs, at least the second sun being connected to the torque vectoring unit to redistribute torque between the first sun and the second sun, the first planet set also meshing with a third sun, the third sun being connected to the torque vectoring unit to redistribute torque between the first sun and the second sun.
A method of constructing a drive device for a motor vehicle comprising:
- providing a differential gear including a first planet set, a second planet set, a common planet carrier, a first sun, a second sun and a third sun, the first planet set and the second planet set being rotatably mounted on the common planet carrier, the first planet set meshing at least with the first sun, the second planet set meshing at least with the second sun, the first planet set and the second planet set meshing with one another at least in pairs, the first planet set also meshing with the third sun;
- providing a torque vectoring unit having an electric machine;
- and
- connecting the differential gear to the torque vectoring unit, at least the second sun being connected to the torque vectoring unit to redistribute torque between the first sun and the second sun, the third sun being connected to the torque vectoring unit to redistribute torque between the first sun and the second sun.
