The invention discloses an electric motorcycle. The electric motorcycle comprises a frame, a motorcycle body covering part, a walking assembly and a driving assembly. The driving assembly comprises a reduction gearbox and a bearing pressing plate assembly, the reduction gearbox is provided with a front shell and a motor rotor, the front shell comprises a bearing seat, the bearing seat is provided with a bearing chamber, the bearing chamber is used for containing a front bearing and a rotating shaft of the motor rotor, an opening of the bearing chamber faces the motor rotor, and the bearing pressing plate assembly is arranged on the bearing seat. The bearing pressing plate assembly comprises a bearing pressing plate, a locking piece and a limiting piece, the bearing pressing plate is provided with a mounting hole and a limiting groove, the locking piece penetrates through the mounting hole and is fixed to the bearing seat, the limiting groove is provided with an inlet, and the limiting piece is configured to enter or leave the limiting groove from the inlet along with rotation of the bearing pressing plate. The bearing pressing plate can rotate around the locking piece to be close to or away from the opening. According to the scheme, blind installation of the bearing pressing plate is avoided, so that the installation efficiency is improved, and meanwhile the size of the driving assembly can be reduced.

    本申请公开一种电动摩托车,包括:车架、车身覆盖件、行走组件以及驱动组件。驱动组件包括减速箱和轴承压板组件,减速箱具有前壳体和电机转子,前壳体包括轴承座,轴承座具有轴承室,轴承室用以容置前轴承和电机转子的转轴,轴承室的开口朝向电机转子,轴承压板组件设于轴承座。轴承压板组件包括轴承压板、锁紧件以及限位件,轴承压板设有安装孔与限位槽,锁紧件贯穿安装孔并固定于轴承座,限位槽具有入口,限位件被配置为能够随轴承压板的转动从入口进入或远离限位槽,轴承压板能够绕锁紧件转动以靠近或远离开口。上述方案中,避免了轴承压板的盲装,从而提高了安装效率,同时也能够减小驱动组件的体积。
