The fluid flowing into the passive end device 5 flows out of the passive inlet passage 52, enters the third lower flow guiding opening 238 through the third main flow channel 1131 via the third flow guiding channel 231, then flows into the third outer ring channel 11362 through the third passive inlet sub-flow channel 11323 and the passive inlet outer communicating channel 11361 in sequence, flows into the third active inlet sub-flow channel 11223 through the passive inlet outer channel 1136 via the lower flow channel 115, the active inlet outer channel 1126, the second outer ring channel 11262 and the active inlet outer communicating channel 11261 in sequence, and flows back to the active end device 4 through the active inlet passage 42 via the second lower flow guiding opening 228, the second flow guiding channel 221 and the second main flow channel 1121 in sequence.

If the driving end device 4 is set as a power output device (e.g. an automobile engine) and the driven end device 5 is set as a power receiving device (e.g. a transmission device), the driving end device 4 drives the driven end device 5 in reverse direction, and the function is similar to the reverse gear (R) during driving.

Referring to fig. 12, a fourth implementation of the above structure according to the present invention is disclosed, in the schematic diagram of the present embodiment, the first, second, third, and fourth switching members 21, 22, 23, and 24 are respectively cut at the positions of the first, second, third, and fourth lower diversion ports 218, 228, 238, and 248, and the seat body 11 is horizontally cut at the positions of the first, second, third, and fourth internal circulation channels 1115, 1125, 1135, and 1145 corresponding to the same height as the upper channel 1212; when the first, second, third, and fourth switches 21, 22, 23, and 24 are turned (moved) to the first, second, third, and fourth lower diversion ports 218, 228, 238, and 248 respectively corresponding to the fourth active output branch channel 11124, the fourth active input branch channel 11224, the fourth passive input branch channel 11324, and the fourth passive output branch channel 11424, the fluid flowing out from the active output channel 41 of the active end device 4 can enter the first diversion channel 211 through the first main channel 1111, then sequentially flow into the first internal circulation channel 1115 through the fourth active output branch channel 11124 and the second active output internal connection channel 11152 from the first lower diversion port 218, sequentially flow into the second internal circulation channel 1125 through the first active output internal connection channel 11151, the second active output branch channel 11122, the first longitudinal channel 1161, and the second active input branch channel 11222 from the first active input internal connection channel 11251, the second active input interconnection 11252 passes through the fourth active input branch channel 11224 and the second lower diversion port 228 sequentially, and finally flows back to the active end device 4 through the second diversion channel 221, the second main flow channel 1121 and the active input passage 42, forming an active end internal fluid circulation without outputting or inputting fluid to the third and fourth control portions 113, 114.

The fluid flowing out of the passive end device 5 from the passive output passage 51 can enter the fourth lower diversion port 248 through the fourth diversion channel 241 via the fourth main flow channel 1141, however, since the fourth passive output branch channel 11424 is set to be in a closed state and no channel for the fluid to flow is formed, the (bidirectional) flow of the fluid in the passive output passage 51 is blocked, and meanwhile, since the fourth passive input branch channel 11324 is also set to be in a closed state and no channel for the fluid to flow is formed, the passive input passage 52 cannot form a channel for the fluid to flow, the (bidirectional) flow of the fluid in the passive input passage 52 is also blocked, and the fluid circulation between the passive output passage 51 and the passive input passage 52 of the passive end device 5 cannot be formed.

If the active end device 4 is set as a power output device (e.g., an automobile engine) and the passive end device 5 is set as a power receiving device (e.g., a transmission device), the active end device 4 forms a fluid circulation without outputting fluid to the third and

fourth control portions

113 and 114, and the passive end device 5 forms a locked state in which fluid cannot circulate, and functions like a parking (P) gear during driving.

In summary, the mobile gear control device between the active and passive devices of the vehicle of the present invention can simplify the overall structure, improve the convenience of operation, and stabilize the quality of fluid transmission.
