The invention relates to an electric wheel structure directly driven by a motor, which has a compact structure. The electric wheel structure directly driven by the motor comprises a wheel unit and a power unit, wherein the wheel unit comprises a wheel support frame, a bearing, a wheel and an end cover; the power unit comprises a motor, an orthogonal speed reducer, a coaxial speed reducer and a brake device, the orthogonal speed reducer is provided with vertical output shaft mechanisms which are linked mutually, wherein one end of a first output shaft is connected to the motor and the other end of the first output shaft is connected to the brake device; a second output shaft penetrates through the wheel support frame and is connected to the input end of the coaxial speed reducer; the output end of the coaxial speed reducer is connected to the end cover, and the end cover and the end of the wheel are fixed; the motor, the orthogonal speed reducer, the wheel support frame, the coaxial speed reducer, the end cover and the wheel are linked to a whole body through connecting pieces. By adopting a manner of the nested installation of a split reducing mechanism and the wheel, the speed reducer and the control motor are integrally designed, so that the purposes of small size, high transmission efficiency and convenience for installation are achieved.
Description
technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an electric wheel structure directly driven by motor power. Background technique [0002] The power transmission structure of traditional electric vehicles, the motor that outputs power, and the wheel structure that carries the load of the vehicle body are separated. The motor and wheels of this type of mechanism are connected to transmit power through an external power transmission structure. The transmission structure is In the exposed form (such as US Pat. No. 5,934,401, US Pat. No. 5,937,964), the power transmission structure is usually used as the power transmission by belts and chains without joints. The power transmission structure is loose and requires a large installation space. Moreover, since the alignment accuracy of the fixing devices of the motor and the wheels is not easy to control, and the transmission structure of the belt and chain will affect the efficie...
