[0004] The technical means adopted by this utility model to solve the above-mentioned problems is as follows: an integrated system for uninterrupted power drive of an electromagnetic retarder four-motor two-speed drive, including a first motor and a first input shaft, a first motor and a first input shaft, and a first shift group connected in parallel, wherein the first motor is connected to the first shift group through the first input shaft, and the first motor is connected to the first shift group through the first input shaft; it also includes a second motor and a second input shaft, a second motor and a second input shaft, and a second shift group connected in parallel, wherein the second motor is connected to the second shift group through the second input shaft, and the second motor is connected to the second shift group through the second input shaft; it also includes an output shaft and an output motor connected in parallel, wherein both the first shift group and the second shift group mesh with the output motor to transmit power to the output shaft.

Both the second gear one and the second gear three mesh with the second gear two. This transmits the power of the second motor one and the second motor two to the second higher gear position.

[0012] Furthermore, the second shift group also includes second gear four, second gear five, second gear six, second gear seven, second intermediate shaft one, and second intermediate shaft two.

[0030] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only, representing schematic diagrams only, not actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0031] like Figures 1-5 As shown, an electromagnetic slow-speed four-motor two-speed drive power uninterrupted integrated system includes four motors providing power: a first motor 11, a first motor 21, a second motor 22, and a second motor 23. The first motor 11 and the first motor 21 form one group, and the second motor 21 and the second motor 23 form another group, arranged in a modular and symmetrical manner, synchronously transmitting power to the output shaft 3.

[0032] like Figure 2 As shown, the entire integrated system also includes a first input shaft 12, a second first input shaft 13, a first shift group 100, and an output gear 31. The first shift group 100 further includes a first main intermediate shaft 101 and a first output gear 111. The first input shaft 12 is connected to both the first motor 11 and the first shift group 100, and the second first input shaft 14 is connected to both the first motor 13 and the first shift group 100, synchronously transmitting the power of the first motor 11 and the first motor 13 to the first shift group 100. The intermediate shaft 101 of the first shift group is connected to its first output gear 111, which in turn meshes with the output gear 31, which is connected to the output shaft 31. In this way, the power of the first motor 11 and the first motor 13 is reduced in speed by the first shift group 100 before being output.

[0033] Similarly, such as Figure 4As shown, the entire integrated system also includes a second input shaft 22, a second input shaft 23, and a second shift group 200. The second shift group 200 includes a second main intermediate shaft 201 and a second output gear 211. The second input shaft 22 is connected to both the second motor 21 and the second shift group 200, and the second input shaft 24 is connected to both the second motor 23 and the second shift group 200, synchronously transmitting the power of the second motor 21 and the second motor 23 to the second shift group 200. The intermediate shaft 201 of the second shift group is connected to its second output gear 211, which in turn meshes with an output gear 31, which is connected to an output shaft 3. In this way, the power of the second motor 21 and the second motor 23 is reduced in speed by the second shift group 200 before being output. Therefore, the power of the first motor 11 and the first motor 23 is symmetrically and synchronously transmitted to the output shaft with the power of the second motor 21 and the second motor 23, which enables the gearbox to more effectively couple the power from different motors, reduce energy loss, and improve transmission efficiency.

[0034] like Figure 2 and Figure 3As shown, the first shift group 100 also includes a first gear 112, a first gear 2 113, a first gear 3 114, a first gear 4 115, a first gear 5 116, a first gear 6 117, a first gear 7 118, a first constant meshing shaft 102, a first intermediate shaft 103, a first intermediate shaft 2 104, a first shift spline 121, a first low gear 131, and a first high gear 132. The first low gear 131 and the first high gear 132 are both compound gears. The first low gear 131 includes a first low gear large gear 1311 and a first low gear small gear 1312. The first high gear 132 includes a first high gear large gear 1321 and a first high gear small gear 1322. The first input shaft 12 is connected to the first gear 112, and the first input shaft 2 14 is connected to the first gear 3 114. The first gear 112 and the first gear 3 simultaneously mesh with the first gear 2 113. The first constantly meshing shaft 102 connects the first gear 2 113 to the first high-gear 1321. Thus, the power of the first motor 11 and the first motor 2 13 is transmitted to the first high-gear position 132. Simultaneously, the first high-gear 1321 meshes with the first gear 4 115 and the first gear 5 116. The first intermediate shaft 103 is connected to the first gear 4 115 and the first gear 6 117, and the first intermediate shaft 2 104 is connected to the first gear 5 116 and the first gear 7 118. The first gear 6 117 and the first gear 7 118 both mesh with the first low-gear 1311. Thus, the power of the first motor 11 and the first motor 2 13 is transmitted to the first low-gear position 131 via the first high-gear position 132. Both the first low-gear pinion 1312 and the first high-gear pinion 1322 are engaged with the first shift spline 121, and the first main intermediate shaft 101 is connected to the first shift spline 121. The compound gear of the first low-gear position 131 is sleeved on the first main intermediate shaft 101, and the first shift spline 121 is engaged with the first low-gear pinion 1312 or with the first high-gear pinion 1322 to output first-gear power or second-gear power.

[0035] Accordingly, such as Figure 4 and Figure 5As shown, the second shift group 200 also includes a second gear 1 212, a second gear 213, a second gear 3 214, a second gear 4 215, a second gear 5 216, a second gear 6 217, a second gear 7 218, a second constant meshing shaft 202, a second intermediate shaft 1 203, a second intermediate shaft 204, a second shift spline 221, a second low gear position 231, and a second high gear position 232. Both the second low gear position 231 and the second high gear position 232 are compound gears. The second low gear position 231 includes a second low gear large gear 2311 and a second low gear small gear 2312. The second high gear position 232 includes a second high gear large gear 2321 and a second high gear small gear 2322. The second input shaft 22 is connected to the second gear 212, and the second input shaft 24 is connected to the second gear 214. The second gear 212 and the second gear 214 simultaneously mesh with the second gear 213. The second constantly meshing shaft 202 connects the second gear 213 to the second high-gear 2321. This transmits the power of the second motor 21 and the second motor 23 to the second high-gear position 232. Simultaneously, the second high-gear 2321 meshes with the second gear 4 215 and the second gear 5 216. The second intermediate shaft 203 is connected to the second gear 4 215 and the second gear 6 217, and the second intermediate shaft 204 is connected to the second gear 5 216 and the second gear 7 218. The second gear 6 217 and the second gear 7 218 both mesh with the second low-gear 2311. Thus, the power of the second motor 21 and the second motor 23 is transmitted to the second low-gear position 231 via the second high-gear position 232. The second low-gear pinion 2312 and the second high-gear pinion 2322 both engage with the second shift spline 221, while the second main intermediate shaft 201 is connected to the second shift spline 221. The compound gear of the second low-gear position 231 is sleeved on the second main intermediate shaft 201, and outputs first-gear power or second-gear power by meshing with the second low-gear pinion 2312 or the second high-gear pinion 2322 through the second shift spline 221.

[0036] like Figure 6 As shown, when outputting the second power level, the power of the first motor 11 is transmitted sequentially through the first input shaft 12 and the first gear 112 to the first gear 113. The power of the second motor 13 is transmitted sequentially through the first input shaft 14 and the first gear 114 to the first gear 113. Then, it is transmitted through the first high gear 132 to the first shift spline 121, the first main intermediate shaft 101, the first output gear 111, and the output gear 31, finally reaching the output shaft 3. The power transmission method of the second motor 21 and the second motor 23 is similar.

[0037] like Figure 7As shown, when outputting the first power level, the power is simultaneously transmitted from the first high-gear gear 1321 of the first high-gear position 132 to the first gear four 115 and the first gear five 116. After the first gear four 115, the power is transmitted through the first intermediate shaft one 103 and the first gear six 117 to the first low-gear position 131. After the first gear five 116, the power is transmitted through the first intermediate shaft two 104 and the first gear seven 118 to the first low-gear position 131, then to the first shift spline 121, the first main intermediate shaft 101, the first output gear 111, the output gear 31, and finally to the output shaft 3. The power transmission method of the second motor one 21 and the second motor two 23 is similar. Example 2

[0038] This embodiment is basically the same as the above embodiment, except that: the output shaft 3 of this embodiment is equipped with an electromagnetic retarder 4 to better adjust the output power and further improve the flexibility and efficiency of the system.

[0039] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the protection scope of the present invention, which should be defined by the claims.
