The invention discloses a planetary wheel speed reducer. The planetary wheel speed reducer comprises a main shaft connected with a high-speed part, planetary wheels, a fixed inner tooth ring fixedly arranged, and an output inner tooth ring connected with a low-speed part. The axes of the planetary wheels are eccentric relative to the axis of the main shaft and are arranged in parallel. Center shafts in the planetary wheels are connected to the main shaft, and the planetary wheels can rotate around the respective center shafts in the planetary wheels. Each planetary wheel comprises a first-stage gear used for meshing transmission with the fixed inner tooth ring and a second-stage gear used for meshing transmission with the output inner tooth ring. In each planetary wheel, the first-stage gear is coaxially and fixedly arranged on one side of the second-stage gear. The planetary wheels in the planetary wheel speed reducer conduct a circular movement around the main shaft and a rotation movement, the two movements are superimposed and transmitted to the output inner tooth ring, and thus the planetary wheel speed reducer has a large transmission ratio, and the planetary wheel speed reducer is simple in structure and convenient to machine. The invention further discloses mechanical and electronic integration equipment comprising the planetary wheel speed reducer, and the planetary wheel speed reducer can guarantee the transmission ratio and is simple in structure.

The invention relates to an integrated single-trailing-arm gear-reducing type electric wheel drive system. A drive motor is fixed on a frame, and assembled with a drive wheel, planet gears, tanks and a single trailing arm to form an integrated structure, so that unsprung mass of an automobile is reduced. Tanks A, tanks B, the single trailing arm and the frame form an articulated four-bar mechanism, when wheels hop up and down under the action of random road excitation, the single trailing arm and the tanks A and B also rotate around respective rotation axes, and by the mechanism, transmission ratio can be ensured unchanged when the center distance between the motor and a driven planet gear changes due to road input excitation. By the novel wheel reduction and transmission mechanism transmitting motor power to the driven planet gear (wheel rim), the transmission ratio between the motor and the driven planet gear can be ensured not to change with the center distance without the help of a constant-speed universal transmission shaft device. The integrated single-trailing-arm gear-reducing type electric wheel drive system has the advantages of simplicity of the wheel reducing mechanism and high transmission efficiency.
