Embodiment 1

[0040] This embodiment relates to an electric drive assembly, including a plurality of motors, two output half shafts 60 connected by a differential 62 , and a central shaft 40 sleeved on one of the output half shafts 60 . Wherein, a first transmission mechanism is provided between each motor and the central shaft 40 , and a second transmission mechanism and a third transmission mechanism are provided between the central shaft 40 and the differential 62 .

[0041] like figure 1 As shown in , as a preferred implementation form, this embodiment specifically uses two motors as an example to describe the structure of the electric drive assembly. Wherein, each first transmission mechanism has a first intermediate shaft 30 connected to the motor transmission, a first shifting device 3 sleeved on the first intermediate shaft 30, and a first shifting device 3 and a center shaft 40 Between the first gear transmission unit and the second gear transmission unit with different transmissi...

Embodiment 2

[0079] This embodiment also relates to an electric drive assembly, which has roughly the same structure as the electric drive assembly in Embodiment 1, the difference is that, as image 3 As shown in , still use two motors as an example for illustration. In this embodiment, each motor is connected to the first intermediate shaft 30 through the first transmission gear set, and is offset to one side of the first intermediate shaft 30 . The second intermediate shaft 50 and the first intermediate shaft 30 are arranged in parallel and staggered on the radially outer side between the central shafts 40, and each motor is also arranged in a parallel and staggered manner with the second intermediate shaft 50 on the radially outer side of the central shaft 40, and each motor is also close to Set in the differential 62.

[0080] Understandably, image 3 The arrangement of the electric drive assembly in is a modification of the second structure in the first embodiment. And, still refer...

Abstract

The invention provides an electric drive assembly which comprises a plurality of motors, two output half shafts connected through a differential mechanism and a center shaft arranged on one of the output half shafts in a sleeving mode, a first transmission mechanism is arranged between each motor and the center shaft, and a second transmission mechanism and a third transmission mechanism are arranged between the center shaft and the differential mechanism. Each first transmission mechanism is in transmission connection with the central shaft through a first gear transmission unit or a second gear transmission unit alternatively, the second transmission mechanism is in transmission connection with the differential mechanism through a third gear transmission unit or a fourth gear transmission unit alternatively, and the third transmission mechanism is in transmission connection with the differential mechanism through a fifth gear transmission unit, or is directly in transmission connection with the differential. According to the electric drive assembly, gears can be conveniently adjusted, different torques can be output, the electric drive assembly is further suitable for different vehicle speeds and loads, and meanwhile the reliability and stability in the using process can be improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an electric drive assembly. Background technique [0002] With the country's increasing requirements for energy conservation and environmental protection, as well as the continuous enhancement of people's awareness of environmental protection, electric vehicles are favored by more and more people, and have become one of the main means of transportation for people's daily travel. The quality of the electric drive assembly of an electric vehicle directly affects the performance. However, the current electric drive assembly has disadvantages such as large space occupation, high cost, and low transmission efficiency. Not only does it make the electric drive assembly inconvenient to arrange in the car, but also the unreasonable design of the electric drive assembly easily leads to low smoothness and reliability of shifting. [0003] And adopt the electric drive assembly structure...
