The invention relates to an electric vehicle powertrain assembly with nested shafts, and relates to a power transmission system. The power transmission system comprises a first transmission gear driven by a first motor and a second transmission gear driven by a second motor. The first transmission gear and the second transmission gear are arranged along an axis. The first transfer gear includes a first extension, and the second transfer gear includes a second extension disposed radially within and axially overlapping the first extension. The powertrain includes a bearing system disposed between the first transfer gear and the second transfer gear, between any transfer gear and a stationary component, or a combination thereof. In some embodiments, the powertrain includes a clutch assembly disposed between the first transfer gear and the second transfer gear, the clutch assembly abutting the first transfer gear and abutting the second transfer gear. The clutch assembly allows the transfer gears to be locked or otherwise engaged to improve torque transfer.
本发明题为“具有嵌套轴的电动车辆动力系组件。”本发明涉及一种动力传动系统,该动力传动系统包括由第一马达驱动的第一传动齿轮和由第二马达驱动的第二传动齿轮。该第一传动齿轮和该第二传动齿轮沿着轴线布置。该第一传动齿轮包括第一延伸部,并且该第二传动齿轮包括径向地布置在该第一延伸部内并与该第一延伸部轴向重叠的第二延伸部。该动力传动系统包括布置在该第一传动齿轮和该第二传动齿轮之间、任一传动齿轮和静止部件之间或它们的组合的轴承系统。在一些实施方案中,该动力传动系统包括离合器组件,该离合器组件布置在该第一传动齿轮和该第二传动齿轮之间,该离合器组件对接到该第一传动齿轮并对接到该第二传动齿轮。该离合器组件允许这些传动齿轮被锁定或以其他方式接合以改善扭矩传递。
