Electric drive axle speed reduction structure

The utility model discloses a speed reduction structure of an electric drive axle. The speed reducer comprises a motor module, a first-stage speed reduction structure module and a second-stage speed reduction structure module, the first-stage speed reduction structure module is a planet-like gear transmission device, the second-stage speed reduction structure module is a planet gear transmission device, and power output by the motor module is decelerated by the first-stage speed reduction structure module, then output by the inner gear ring and output to a sun gear of the second-stage speed reduction structure module. A two-stage speed reduction structure is adopted, the total transmission ratio is large, and high-speed motor and part integration can be achieved, so that the servicing massof the electric automobile is effectively reduced, the carrying capacity is increased, the endurance mileage is prolonged, and the market competitiveness is improved. 本实用新型公开了一种电驱桥减速结构，包括电机模块、一级减速结构模块和二级减速结构模块，所述的一级减速结构模块为类行
