The invention relates to a transmission system for an electric vehicle. The transmission system includes: an electric motor configured to provide driving power and including a rotor and a drive shaft driven by the rotor; a decelerator configured to decelerate and increase torque received from the drive shaft, the decelerator including an intermediate drive shaft having a hollow axial passage; and a pumping component configured to deliver a lubricant. The pumping component is mechanically integrated on and driven by the intermediate drive shaft and includes a plurality of channels for supplying lubricant into a hollow axial channel of the intermediate drive shaft and to components disposed on the intermediate drive shaft.

    本公开涉及一种用于电动车辆的传动系统。传动系统包括:电马达,被构造为提供驱动功率,并且包括转子和由转子驱动的驱动轴;减速器,被构造用于减速和增加从驱动轴接收的扭矩,该减速器包括具有中空轴向通道的中间传动轴;和泵送部件,被构造成用于输送润滑剂。泵送部件机械地集成在中间传动轴上并由中间传动轴驱动,并且包括多个通道,用于将润滑剂供应到中间传动轴的中空轴向通道中以及供应到布置在中间传动轴上的部件。
