The bearings (72, 74) are arranged for a drive unit (10) having an electric motor for providing drive for an electric axle and wheel assembly of a vehicle. The drive unit includes a pair of bearings and a reduction gear assembly (12) having a first drive gear mounted to the main shaft of the motor and coaxial therewith, and a first driven gear rotatably coupled to the first drive gear and mounted to the intermediate shaft and coaxial therewith to form an intermediate shaft assembly. The reduction gear assembly includes a second drive gear mounted to and coaxial with the intermediate shaft, and a second driven gear rotatably coupled with the second drive gear. A first bearing of the pair of bearings is mounted to the diaphragm and to the intermediate shaft assembly between the first driven gear and the second driving gear to reduce a distance between the first bearing and the second bearing.

    轴承(72、74)布置用于具有电动马达的驱动单元(10),该驱动单元用于为车辆的电动车桥和车轮组件提供驱动。驱动单元包括一对轴承和减速齿轮组件(12),减速齿轮组件具有安装到马达的主轴并与其同轴的第一驱动齿轮,以及可旋转地联接到第一驱动齿轮并安装到中间轴并与其同轴以形成中间轴组件的第一从动齿轮。减速齿轮组件包括安装到中间轴并与中间轴同轴的第二驱动齿轮,以及与第二驱动齿轮可旋转地联接的第二从动齿轮。所述成对轴承中的第一轴承安装到隔板并在第一从动齿轮和第二驱动齿轮之间安装到所述中间轴组件上,以减小在第一轴承和第二轴承之间的距离。
