Problems solved by technology

[0006] (1) The distance between the center of the gearbox and the direction of space is relatively long;
[0007] (2) Insufficient utilization of the space between the reducer and the motor, resulting in waste of space;
[0008] (3) The overall size of the electric drive system is the largest, which is not conducive to the design of the whole vehicle; there are many transfer structures, which is not conducive to the improvement of NVH performance

Embodiment 1

[0045] Such as Figure 2-9 As shown, the three-in-one electric drive integrated system for new energy vehicles of the present invention includes a half shaft mechanism 1, a controller 2, a motor 3 and a gearbox 4, and the motor 3 includes an integrated housing 31 and an integrated housing 31 fixed at one end thereof. The end cover 32; the gearbox 4 is connected to the other end of the integrated housing 31 of the motor 3; the two ends of the half shaft mechanism 1 are fixedly connected to the integrated end cover 32 and the other end of the integrated housing 31 respectively. On the box 4; the integrated housing 31, the integrated end cover 32 and the half-axis mechanism 1 together form a distorted space; the controller 2 is installed in the distorted space and fixed to the motor 3 Integrated housing 31.

Embodiment 2

[0053] Such as Figure 10 As shown, another structural form of the integrated end cover 32 is: the integrated end cover 32 has a motor rear end cover 321, a movable bracket 1a and a second positioning hole 323; the motor rear end cover 321 and the movable bracket 1a is a mechanical connection, the movable bracket 1a is installed on the outside of the motor rear end cover 321, and the motor rear end cover 321 is installed on the motor housing 311, and the movable bracket 1a and the half shaft mechanism 1 are connected by bearings 12 fixed. The main difference in the layout of this scheme is that the rear end cover of the motor and the half-shaft fixed bracket are transfer structures, and integrated structures, both of which can improve the space utilization rate of the electric drive system and reduce the space size. The difference is that the transfer structure is relatively convenient to disassemble. , but the vehicle NVH performance is relatively poor.

Abstract

The invention discloses a three-in-one electric driving integrated system of a new energy vehicle. The system comprises a half-shaft mechanism, a controller, a motor and a transmission box, wherein the motor is provided with an integrated housing and an integrated end cover; the two ends of the half-shaft mechanism are fixedly connected with the integrated housing and the integrated end cover; thetransmission box is connected with the integrated housing of the motor; the integrated housing, the integrated end cover and the half-shaft cooperatively surround to form an odd space; the controlleris installed in the odd zero space and fixed to the housing of the motor. The motor housing and the right end cover of the transmission box are designed into an integrated structure, the output half-shaft supporting frame and the motor housing rear end cover are designed into an integrated structure, a half-shaft cage is moved back to the outer side of the rear end cover of the motor, so that previous space which is preserved for preventing the moving interfering of the output half-shaft and the motor and the controller is omitted, and therefore the central spacing between the output half-shaft of the input half-shaft of the transmission box is reduced to the minimum through the designing.

Description

technical field [0001] The invention relates to an electric drive system for a new energy vehicle, in particular to a three-in-one electric drive integration system for a new energy vehicle. Background technique [0002] At this stage, various companies related to the production and manufacturing of new energy vehicles and electric drive systems are actively developing miniaturized electric drive systems. The purpose is to reduce the space size of traditional electric drive system structures and improve the integration of motors, controllers, and reducers Optimizing the integrated structural layout of the motor, reducer and controller is beneficial to the overall vehicle layout and meets the trend requirements of new energy vehicle integration, miniaturization and light weight. [0003] In the prior art, the existing technical solutions make design improvements regarding the structural arrangement of the electric drive system of the new energy vehicle. For example, a Chines...
