The invention relates to a motor torque increasing device and a hub motor using the same, the motor torque increasing device comprises a motor shaft and a driving input gear mounted on the motor shaft, the driving input gear is rotatably connected with the motor shaft, the driving input gear is connected with a torque increasing assembly, and the torque increasing assembly is connected with the motor shaft. The torque increasing assembly comprises a transmission gear set and an output gear which are installed in the motor, the output gear is fixed to the motor shaft, and the transmission gear set comprises a first gear meshed with the driving input gear and a second gear meshed with the output gear. Compared with the prior art, high-speed small-torque revolution of the driving input gear is automatically converted into low-speed large-torque revolution of the transmission gear set through the distance increasing assembly, and then rapid starting of the electric vehicle is achieved.
本发明涉及一种电机转矩增大装置及使用该装置的轮毂电机,包括电机轴和安装在电机轴上的主动输入齿轮,所述主动输入齿轮与所述电机轴之间为可转动连接,所述主动输入齿轮连接有增矩组件,所述增矩组件包括安装在电机内部的传动齿轮组和输出齿轮,所述输出齿轮固定在所述电机轴上,所述传动齿轮组包括与所述主动输入齿轮相啮合的第一齿轮以及与所述输出齿轮相啮合的第二齿轮。与现有技术相比,本发明通过增距组件使得主动输入齿轮的高速小转矩自转变为传动齿轮组的低速大转矩公转,进而实现电动车的快速启动。
