Embodiment 1

[0023] Figure 1 to Figure 2 An embodiment of the electric drive axle of the present invention is shown. The electric drive axle of this embodiment includes a drive motor 2 and two axle shafts 10, and the two axle half shafts 10 are coaxially arranged on the drive motor Two ends of the rotating shaft 1 of 2, the rotating shaft 1 is a hollow shaft, and the rotating shaft 1 is pierced with a transmission shaft 13, and the two ends of the transmission shaft 13 are connected to the two axle shafts 10 respectively. Wherein, the transmission between the rotating shaft 1 and the transmission shaft 13 can be realized through key connection, tight fit, etc., and the transmission between the transmission shaft 13 and the axle shaft 10 can be realized through key connection, coupling, etc., for example.

[0024] In the electric drive axle, two axle shafts 10 are coaxially arranged on both sides of the rotating shaft 1 of the driving motor 2. The rotating shaft 2 of the driving motor 1 ad...

Embodiment 2

[0030] Figure 3 to Figure 4 An embodiment of the electric drive axle of the present invention is shown. The structure of the electric drive axle of this embodiment is basically the same as that of Embodiment 1, the difference lies in: the shells of the two axle shafts 10 and the drive motor 2 A connecting screw 9 is perforated on the casing 3, that is, the two threaded holes 8 in the first embodiment are connected, and fastening nuts 14 are provided at both ends of the connecting screw 9. Compared with Embodiment 1, the installation structure of the housing of the axle shaft 10 on the casing 3 of the drive motor 2, the connecting screw 9 can independently withstand the impact and load of the two axle shafts 10, for the casing 3 The material and strength requirements are reduced.

Embodiment 3

[0032] The new energy vehicle of this embodiment includes the electric drive axle mentioned above.

[0033] The new energy vehicle includes the electric drive axles of the above-mentioned embodiments, so it also has the above-mentioned advantages.

Abstract

The invention discloses an electrically-driven axle which comprises a driving motor and two axle half shafts, the two axle half shafts are coaxially arranged at the two ends of a rotating shaft of the driving motor, the rotating shaft is a hollow shaft, a transmission shaft is arranged in the rotating shaft in a penetrating mode, and the two ends of the transmission shaft are in transmission connection with the two axle half shafts respectively. The invention further discloses a new energy automobile which comprises the electrically-driven axle. The Electrically-driven axle and the new energy automobile have the advantages of light weight, small volume, high integration level, high transmission efficiency and the like.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an electric drive axle and a new energy vehicle. Background technique [0002] In recent years, the new energy vehicle industry has developed vigorously. Among them, the first generation of axles generally adopts the method of traditional axles plus driving motors. The structural changes of traditional axles and driving motors are small, low in cost, and easy to implement. For this type of drive axle, the drive motor is generally attached to the electric drive axle in a vertical or horizontal manner. With the advancement of technology and the expansion of the application field of electric drive axles, the limitations of this method have gradually emerged: large volume and heavy weight, which affect the efficiency, reliability and floor height of the drive system, etc., which limit the use of electric drive axle vehicles. Market competitiveness and marketing promotion. Contents of t...
