The invention discloses a transmission lubricating structure for an electric vehicle. The transmission lubricating structure comprises a frame, a hub, a motor and a wheel shaft. A transmission installation end cover is arranged at the end of a shell of the motor, a transmission installation cavity is formed in the transmission installation end cover, a transmission assembly is arranged in the transmission installation cavity and comprises a gear ring and a power output shaft disc, and the end of a rotating shaft of the motor is in meshing transmission with the gear ring. The wheel shaft penetrates through the transmission installation end cover and the power output shaft disc to be connected, the transmission installation cavity is a sealed cavity, lubricating oil is injected into the transmission installation cavity, and the gear ring and the power output shaft disc are partially located in the lubricating oil in the transmission installation cavity. A transmission connection structure between the output shaft of the motor and the hub is redesigned, the output shaft of the motor and the axle in the electric car are not traditionally coaxially installed, transmission parts between the motor and the hub can be immersed in lubricating oil, the transmission lubricating effect is improved, the transmission reliability is guaranteed, and meanwhile rotation positioning between the transmission parts is reliable and stable.
本发明公开了一种电动车用传动润滑结构,包括车架、轮毂、电机、轮轴;电机的壳体端部设置有传动安装端盖,传动安装端盖中设置有传动安装腔,传动安装腔中设置有传动组件,传动组件包括齿轮圈、动力输出轴盘,电机的转轴端部与齿轮圈啮合传动;轮轴从传动安装端盖、动力输出轴盘穿过进行连接,传动安装腔为一密封腔体、其内注有润滑油,齿轮圈、动力输出轴盘部分处于传动安装腔中的润滑油中。本发明重新设计电机输出轴与轮毂之间的传动连接结构,电机输出轴与电车中的轮轴不是传统的同轴心安装,电机与轮毂之间的传动部件可以浸在润滑油中,提高传动润滑的效果,保证传动的可靠性,同时传动部件之间转动定位可靠、稳定。
