AI Technical Summary
Technical Problem
The large amount of lubricating oil used in the electric drive axles of existing heavy-duty vehicles results in high usage and maintenance costs.
Method used
Two baffles and sealing rings are installed in the inner cavity of the axle housing to separate it into independent chambers to isolate the shaft tube cavity and reduce the inflow of lubricating oil. Rubber and plastic foam tubes are used as sleeve guides and shock absorbers.
Benefits of technology
This reduces the amount of lubricating oil used, lowers the weight and maintenance costs of the electric drive axle, and improves assembly efficiency and noise reduction.

Abstract
The utility model discloses an electric drive axle structure and electric drive axle, electric drive axle structure includes axle housing, two separate components and two half shafts, the utility model discloses the emphasis is at: every separate component includes a baffle and a sealing washer, a baffle is located between the axle pipe of axle housing and the one end of differential, another baffle is located between the other axle pipe of axle housing and the other end of differential, and two baffles cooperate with the inner chamber to make the inner chamber separate into a independent chamber for accommodating differential, every baffle still is provided with the through hole of inside and outside through it, a sealing washer cooperates with a through -hole, makes the independent chamber and the pipe cavity of two axle pipes insulate, two half shafts are arranged in two axle pipes respectively, and one half axle is close to the inner end of differential and the sealing washer cooperation and stretches into independent chamber to be connected with differential. Through this structure design, thereby can prevent the lubricating oil in the pipe cavity of two axle pipes and flow into independent chamber, not only reduce the use amount of lubricating oil, and effectively reduce the weight of electric drive axle.
