Title: ELECTRIC DRIVE FOR A VEHICLE, AND VEHICLE HAVING THE ELECTRIC DRIVE
Abstract:
In the realization of hybrid vehicles or electric vehicles, new design possibilities for the integration of the electric motors have arisen. The problem addressed by the invention is that of proposing an electric drive for a vehicle, which electric drive is designed in a compact and reliable manner. This problem is solved by means of an electric drive (1) for a motor vehicle (2), comprising a gearing segment (6) for transferring the driving torque from an electric motor (5) to two outputs (7a, b) of the electric drive (1), wherein the gearing segment (6) has a differential device (10) having a first and a second sun gear (11, 12) and has a set having first and second planet gears (15, 16), wherein the sun gears (11, 12) are operatively connected to the outputs (7a, b), wherein the first planet gears (15) mesh with the first sun gear (11) and the second planet gears (16) mesh with the second sun gear (12), wherein the first and the second planet gears (15, 16) have the same number of teeth and wherein the first and the second sun gears (11, 12) have the same number of teeth. The first planet gears (15) are designed as long planet gears that extend, at least in some sections, over the second sun gear (12) in the axial direction, wherein the second sun gear (12) has a smaller addendum circle diameter in comparison with the first sun gear (11).
