The output ends of the planetary gear train are respectively connected to the left and right half shafts; a manual parking device is arranged on the left half shaft or the right half shaft. The invention has the advantages of light weight, compact structure, simple installation, high power density, high efficiency and low cost.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a motor drive axle. Background technique [0002] The so-called electric vehicle is a vehicle in which batteries replace fuel and motors replace engines. The current popular new energy vehicles all adopt the traditional drive axle drive mode - "motor + gearbox + drive shaft + drive axle + battery pack", which has a complex structure, many components and low efficiency. Especially for urban electric logistics vehicles, the disadvantages in efficiency and practicality are particularly obvious. One is the small space. Since the electric logistics vehicle adopts the structure of motor + gearbox + drive shaft + drive axle + battery pack, there are many components, which occupy a lot of space in the logistics vehicle. Compared with fuel logistics vehicles, the rear warehouse space is obviously smaller; The second is the high cost. Due to the use of the complex structure of motor + gearbox ...
