Abstract

The invention relates to the technical field of differential mechanisms, in particular to a differential device and a dual-drive power device. The differential device comprises a left outer wheel and a right outer wheel, the right outer wheel and the left outer wheel are coaxially arranged on a center line; the outer planet wheel is arranged on a planet carrier and is in meshed connection with the left outer wheel and the right outer wheel respectively; the left inner wheel is arranged between the left outer wheel and the right outer wheel, and the axis of the left inner wheel extends along the center line; the right inner wheel is arranged between the left outer wheel and the right outer wheel, and the center line of the right inner wheel extends along the center line; and the inner planet wheel is arranged on the planet carrier and is respectively meshed and connected with the left inner wheel and the right inner wheel. The differential device is compact in structure, small in occupied space and easy to arrange and install, the rotating speed difference of the two drivers can be automatically balanced, and the requirement for a control algorithm is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of differential gears, in particular to a differential gear device and a dual-drive power device. Background technique [0002] With the emphasis on environmental protection and the vigorous promotion of clean energy, electric vehicles have been paid more and more attention. Although the high-efficiency working range of the electric motor is larger than that of the traditional internal combustion engine, the working efficiency of the electric motor decreases significantly under the working conditions of low-speed heavy load, low-speed light load and high-speed light load. In addition, the vehicle needs a large torque when climbing and speeding up, and a high speed when driving at a high speed. If the electric motor needs to meet the performance requirements of high torque and high speed at the same time, it will increase the manufacturing difficulty and the total weight. Therefore, the current common soluti...
