The invention discloses an MGU unit of an electronic parking structure in a new energy automobile. The MGU unit comprises a mounting frame, a motor is mounted at one end of the mounting frame, a driving wheel is fixed at the output end of the motor through a coupler, a small belt wheel meshed with the driving wheel is rotatably mounted on the mounting frame, a large belt wheel meshed with the small belt wheel is further rotatably mounted on the mounting frame, the MGU unit further comprises a gear cleaning mechanism and an air blowing assembly, the gear cleaning mechanism used for cleaning gear teeth on the outer side of the large belt wheel is installed on the surface of the mounting frame and is in butt joint with the connecting shaft in the small belt wheel, and the air blowing assembly used for conducting auxiliary cleaning on the gear teeth on the outer side of the large belt wheel is installed on the surface of the mounting frame. By arranging the gear cleaning mechanism on the mounting frame, dust at the meshing position of the large belt wheel and the small belt wheel can be effectively cleaned, and the situation that after dust is adsorbed on the gears, friction force between the gears is increased, and transmission is affected is avoided.
本发明公开了一种新能源汽车中电子驻车结构的MGU单元,包括安装框,安装框一端安装有电机,且电机输出端通过联轴器固定有驱动轮,安装框上转动安装有与驱动轮相啮合的小带轮,且安装框上还转动安装有与小带轮相互啮合的大带轮,还包括齿轮清洁机构和吹风组件,用于对大带轮外侧轮齿清洁的齿轮清洁机构安装于安装框表面,并与小带轮内连接轴对接,用于对大带轮外侧轮齿进行辅助清洁的吹风组件安装于安装框表面,本发明通过在安装框上设计齿轮清洁机构,从而能够有效的对大带轮和小带轮啮合处的灰尘进行清洁,避免齿轮上吸附灰尘后,会对齿轮之间的摩擦力增大,影响传动。
