The invention discloses an electric driving system, a power system of an electric automobile and the electric automobile, the electric driving system comprises a box body, a driving motor, a first planet row, a second planet row, a differential mechanism and a gear shifting mechanism, the driving motor comprises an output shaft, and the first planet row comprises a first sun gear, a first planet gear, a first planet carrier and a first gear ring; the second planet row comprises a second sun gear, a second planet gear structure and a second gear ring, the differential mechanism comprises a differential mechanism shell, the gear shifting mechanism comprises a brake and a clutch, the brake has a braking state and a non-braking state, and the clutch has a combined state and a separated state; wherein when the brake is in a braking state, the clutch is in a separation state; when the brake is in a non-braking state, the clutch is in a combined state; therefore, the electric driving system can output two rotating speeds, namely has two gears, can better adapt to complex road conditions, and is simple in structure, small in size, small in arrangement space and better in adaptability.
Description
technical field [0001] The invention relates to the technical field of electric drive of pure electric vehicles, in particular to an electric drive system, a power system of an electric vehicle and an electric vehicle. Background technique [0002] Electric vehicles have the advantages of clean, pollution-free, high energy efficiency, low noise, etc., which make them have a good industrialization potential. In order to make electric vehicles adapt to complex road conditions, the electric drive system of electric vehicles adopts a two-speed shifting scheme. At present, in the two-speed shifting scheme of the electric drive system, the structure of the shifting mechanism for realizing the two-speed switching is complex, which makes the overall structure of the electric drive system larger, resulting in a larger space required for the layout of the electric drive system and poor adaptability. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to pr...
