Description

Technical Field

[0001] This utility model relates to the field of automotive drive device technology, specifically a drive device for new energy commercial vehicles. Background Technology

[0002] With the development of new energy vehicle technology, there is a growing demand for drive systems that offer strong power, high efficiency, and high load-bearing capacity. However, for the pure electric vehicle market, especially the light truck market, most currently use a single-motor + single-axle drive system combination, which has relatively weak driving and load-bearing capabilities. Utility Model Content

[0003] The main objective of this invention is to provide a drive device for new energy commercial vehicles to solve the problem of weak drive and load-bearing capacity of new energy vehicles in the prior art.

[0004] To achieve the above objectives, this utility model provides a new energy commercial vehicle drive device, including a drive motor, an intermediate shaft 1 connected to the motor output shaft by a gear drive, and a drive axle 1 connected to the intermediate shaft 1 by a gear drive; an intermediate shaft 2 is coaxially arranged on one side of the intermediate shaft 1, a meshing tooth 1 is coaxially fixedly connected to one end of the intermediate shaft 1 near the intermediate shaft 2, and a meshing tooth 2 is coaxially fixedly connected to one end of the intermediate shaft 2 near the intermediate shaft 1; a meshing sleeve is provided on the outer side of the meshing tooth 1 and the meshing tooth 2 to connect or separate the meshing tooth 1 and the meshing tooth 2; an intermediate shaft 3 is connected to the intermediate shaft 2 by a gear drive, and a drive axle 2 is connected to the intermediate shaft 3 by a gear drive.

[0005] Furthermore, the intermediate shaft includes a differential and an intermediate half-shaft connected to the two output ends of the differential.

[0006] Furthermore, both drive axle one and drive axle two include a differential and drive half shafts connected to the two output ends of the differential.

[0007] Furthermore, the differential includes a ring gear, which is fixedly connected to a frame. Planetary gears are rotatably connected to the frame, and the planetary gears mesh with two opposing output bevel gears. Both the ring gear and the output bevel gears are rotatably connected to the differential housing.

[0008] Furthermore, the motor output shaft passes through the drive motor, and the motor output shaft is a hollow shaft. The drive half shaft is coaxially set inside the motor output shaft, and there is a gap between the drive half shaft and the motor output shaft. This arrangement results in a small overall center of gravity offset of the drive axle, good handling stability, and a compact structure, making it easy to install in the vehicle.

[0009] This invention, by setting meshing teeth, meshing sleeves, etc., can realize the connection or separation of drive axle one and drive axle two, so that it can drive both single axle and dual axle; when driving dual axle, it improves the driving and load-bearing capacity of the vehicle.

[0010] This invention achieves full-time four-wheel drive by setting a differential at one point on the intermediate shaft, thereby setting a differential between drive axle one and drive axle two, and thus has a wider range of applications. Attached Figure Description

Detailed Implementation

[0013] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example 1 like Figures 1 to 3As shown in the embodiment of this utility model, a new energy commercial vehicle drive device is provided, including a drive motor 1, a drive axle 4, and a drive axle 2 10; the drive axle 2 10 is located behind the drive axle 4; the motor output shaft 2 of the drive motor 1 is gear-driven connected to an intermediate shaft 3, which is parallel to the motor output shaft 2; the intermediate shaft 3 is a straight shaft, and an intermediate gear for transmission connection with the motor output shaft 2 is fixedly connected to the middle of the intermediate shaft 3; the drive axle 4 is gear-driven connected to the right end of the intermediate shaft 3; an intermediate shaft 2 5 is coaxially arranged on the left side of the intermediate shaft 3, and a meshing gear 6 is fixedly connected to the left end of the intermediate shaft 3. The right end of intermediate shaft 2 5 is coaxially fixedly connected to meshing tooth 2 7; meshing sleeve 8 is provided on the outer side of meshing tooth 1 6 and meshing tooth 2 7, which can connect or separate meshing tooth 1 6 and meshing tooth 2 7, and meshing sleeve 8 is driven to move by a shift fork; when meshing tooth 1 6 and meshing tooth 2 7 are separated, the power of drive motor 1 is transmitted to drive axle 1 4, which is a single-axle drive mode; when meshing tooth 1 6 and meshing tooth 2 7 are connected, the power of drive motor 1 is transmitted to drive axle 1 4 and drive axle 2 10, which is a dual-axle drive mode; intermediate shaft 2 5 is gear-driven connected to intermediate shaft 3 9, intermediate shaft 3 9 is perpendicular to intermediate shaft 2 5, and intermediate shaft 3 9 is gear-driven connected to drive axle 2 10.

[0015] Both drive axle 14 and drive axle 210 include a differential 11 and drive half shafts 13 connected to the two output ends of the differential 11.

[0016] The differential 11 includes a ring gear 1101, which is fixedly connected to a frame 1102 perpendicular to it. Two opposing planetary gears 1103 are rotatably connected to the frame 1102, and the planetary gears 1103 are meshed with two opposing output bevel gears 1104. The ring gear 1101 is the input end of the differential 11, and the output bevel gears 1104 are the output ends of the differential 11. Both the ring gear 1101 and the output bevel gears 1104 are rotatably connected to the differential housing.

[0017] This embodiment, by setting meshing teeth, meshing sleeves, etc., can realize the connection or separation of drive axle one and drive axle two, so that it can drive both single axle and dual axle; when driving dual axle, it improves the vehicle's driving and load-bearing capacity.

[0018] This embodiment is equipped with a drive motor, which transmits power to drive axle one and drive axle two through gear and shaft transmission.

[0019] Example 2 Example 2 also provides a drive device for an energy commercial vehicle, which differs from the drive device for an energy commercial vehicle in Example 1 only in that: the intermediate shaft 3 includes a differential 11 and an intermediate half shaft 12 connected to the two output ends of the differential 11.

[0020] like Figure 4As shown, this embodiment achieves full-time four-wheel drive by setting a differential at one point on the intermediate shaft, thereby setting a differential between drive axle one and drive axle two, and thus has a wider range of applications.

[0021] Example 3 Example 3 also provides a drive device for an energy commercial vehicle, which differs from the drive device for an energy commercial vehicle in Example 2 only in that: like Figure 5 As shown, the motor output shaft 2 passes through the drive motor 1. The motor output shaft 2 is a hollow shaft, and the drive half shaft 13 is coaxially arranged inside the motor output shaft 2. There is a gap between the drive half shaft 13 and the motor output shaft 2. This arrangement results in a small overall center of gravity offset of the drive axle, good handling stability, and a compact structure, which is convenient for vehicle installation.
