Please refer to Figures 4 to 11. After the above-mentioned guide control device A of the present invention is assembled, the first diversion port 26 of the switching member 2 is transferred from the position of the diversion channel 1131 to the adjacent diversion channel 1132; as shown in FIGS. The position blocked by the stopper 1151 corresponding to the flow channel 1131 forms a seal; at this time, the circumscribed The power fluid can be introduced from the main channel 112 (or the branch channel 1131 connected to the first diversion port 26 ), and exported through the diversion channel 21 from the branch channel 1131 connected to the first diversion port 26 (or the main channel 112 ).

The active device C has an active fluid output terminal C1 and an active fluid input terminal C2, and the passive terminal device D has a passive fluid output terminal D 1 and a passive fluid input port D2, and the active output control device A1 communicates with the active fluid output port C1 with its main channel 112 via an active output channel C11, the active input control device A2 communicates with the active fluid input port C2 with its main channel 112 via an active input channel C21, the passive output control device A3 communicates with the passive fluid output port D1 with its main channel 112 via a passive output channel D11, and the passive input control device A4 communicates with its main channel 1 12 communicates with the passive fluid input port D2 through a passive input path D21, so as to form the basic structure of the following application examples.

In Figure 12, it can be seen that the first application state embodiment of the present invention is based on the above-mentioned basic structure.

The fluid output port C1 flows out, passes through the active output channel C11 through the active output control device A1, then flows through the first channel E1 to the active input control device A2, and finally flows back to the active device C through the active input channel C21 through the active fluid input port C2; and the fluid flowing out of the passive device D can flow out through the passive fluid output port D1, pass through the passive output channel D11 through the passive output control device A3, and then flow through the second channel E2 to the passive input control device A4 , and finally flow back to the passive end device D via the passive input channel D21 through the passive fluid input end D2.

When the switching pieces 2 of the guide control devices are connected to the flow channels 1133, the fluids of the main and passive end devices C and D pass through the flow channels 1133 (circulation flow channels 114), pass through the first passage E1 and the second passage E2, and flow back to the main and passive end devices C and D respectively; 1. The second diversion port 27, the circulation port 116, the circulation channel 117, and the circulation connection channel 1140 flow into the circulation channel 114, and then flow into the active input control device through the first channel E1 The circulation channel 114 of A2 passes through the circulation connection channel 1140, the circulation channel 117, the flow port 116, the second guide port 27, and the guide channel 21, and finally flows into the main channel 112 to complete part of the fluid flow back to the active device C, so as to alleviate the impact of the sudden increase in fluid pressure, and the passive device D will also follow a similar fluid path during the switching process of the branch channels 2, and return part of the fluid to the passive device D; from the above, the branch channel 11 33 and the circulation flow channel 114 are flow channels with different functions, but they can share the space to achieve the purpose of saving space.

In this combined form, the active end device C and the passive end device D each form an independent fluid circuit without any power fluid exchange. At this time, the active end device C and D are in a kind of main and passive fluid circuits that do not perform external work. If the active end device C is regarded as a mechanism that can output driving force (such as: a car engine), and the passive end device D is regarded as a mechanism that receives power (such as: a transmission system), then its overall control function is similar (vehicle gearbox) in a neutral (N) state.

Please refer to FIG. 13. It can be seen that the second application state embodiment of the present invention is based on the above-mentioned basic structure. Between one of the sub-channels 1130 of the active output control device A1 and one of the sub-channels 1130 of the active input control device A2, a third passage E3 is connected, and at least one of the sub-channels 1130 of the passive output and input control devices A3 and A4 is a closed channel.

During operation, the first guide port 26 of each switching member 2 of the active output and input control devices A1, A2 is switched to lead to each of the shunt channels 1130, and through the third passage E3, the active end device C is formed An independent fluid circuit; the first guide ports 26 of each of the switching members 2 of the passive output and input control unit devices A3, A4 are also switched to conduct each of the shunt channels 1130, but the passive output and input control unit devices A3, A4 are divided Among the flow channels 1130, at least one is a closed channel, so that the passive device D cannot form a fluid circuit; the fluid flowing out of the active device C can flow from the active fluid output port C1 through the active output control device A1, and then flow through the third channel E3 to the active input control device Set A2, and finally flow back to the active device C through the active fluid input port C2; but at this time, at least one of the first guide ports 26 of the passive output and input control devices A3 and A4 is blocked by a closed shunt channel 1130, so the passive device D cannot flow out the fluid from the passive fluid output port D1, and no fluid can flow back to the passive device D through the passive fluid input port D2.

In this combination form, since the passive fluid output D1 and the passive fluid input D2 connected to the passive output and input control devices A3 and A4 are closed, a fluid circuit cannot be formed. If the active end device C is regarded as a mechanism capable of outputting driving force (such as a car engine), and the passive end device D is regarded as a power receiving mechanism (such as a transmission system), then the active end device C is in a fluid circulation neutral (N) state without external work, and the passive end device D is in a locked state where it cannot move, and its overall control function is similar ( The vehicle transmission) is in Park (P).

Please refer to Figure 14. It can be seen that the third application state embodiment of the present invention is based on the above-mentioned basic structure. A fourth channel E4 is connected between the active output control device A1 and the sub-channel 1131 of the passive input control device A4; the active input control device A2 is connected with the sub-channel 1131 of the passive output control device A3 through a fifth channel E5.

During operation, when the first diversion port 26 of each switching member 2 of the active and passive output control devices A2 and A4 is switched to the position of conducting with each branch channel 1131; at this time, the fluid flowing out of the active end device C can flow out from the active fluid output port C1, pass through the active output control device A1 through the active output channel C11, and then flow through the fourth channel E4 to the passive input control device A4, and then pass through the passive input control device A4 through the fourth channel E4. The input channel D21 flows to the passive device D through the passive fluid input port D2; and the fluid flowing out of the passive device D can flow out from the passive fluid output port D1, pass through the passive output channel D11, pass through the passive output control device A3, and then flow to the active input control device A2 through the fifth channel E5, and then pass through the active input channel C21 through the active The fluid input C2 flows to the active end device C.

When this kind of combination is used in practice, when the active end device C is a force-applying device (which can be regarded as a mechanism that provides driving force; such as: an automobile engine), the passive end device D is a force-receiving device (which can be regarded as a power-receiving transmission device); since the active end device C for applying force is in the same direction as the passive end device D for receiving force, the active end device C for applying force can provide power to drive the passive end device D for power, so as to form a fluid circuit that can perform work. (D) Status.

Please refer to shown in Fig. 15, it can be seen that the fourth application state embodiment of the present invention is a combined application form similar to the aforementioned third application state embodiment. It is based on the above-mentioned basic structure, and a load device L is assembled in the fifth channel E5 in the embodiment shown in Fig. 15 .

The combination structure above is mainly applied when the two main and passive end devices C and D are both force-applying devices (the active end device C can be regarded as a mechanism that provides a driving force, such as a gasoline engine of a hybrid vehicle, and the passive end device D is regarded as a mechanism that provides another driving force, such as an electric motor of a hybrid vehicle). When switching to the position connected to each branch channel 1131, the active and passive output control devices A1, A3, the active and passive input control devices A2, A4 and the load device L are integrated to form a fluid circuit; in this fluid circuit, the fluid power passing through the load device L can be the sum of the output kinetic energy of the two active and passive end devices C and D; as mentioned above, the power fluid outputs power to the load device L (which can be regarded as a stressed transmission mechanism) through the fifth passage E5, and its function is similar to that of a hybrid electric power The gasoline engine and the electric motor of the car output at the same time to drive the transmission mechanism of the car; but if the above-mentioned passive device D does not output power, it is equivalent to the active device C driving the passive device D and the load device L at the same time.

According to the same application, the load device L can also be arranged on the fourth channel E4 between the active output control device A1 and the passive input control device A4, which can also be similar to that shown in Figure 15, so that the load device L can be driven by the fluid kinetic energy after the output power of the active and passive end devices C and D is added and integrated.

Please refer to FIG. 16. It can be seen that the fifth application state embodiment of the present invention is based on the above-mentioned basic structure. A sixth channel E6 is connected between the sub-channels 1132 of the main and passive output control devices A1 and A3, and a seventh channel E7 is connected between the sub-channels 1132 of the main and passive input control devices A2 and A4.

During operation, when the main and passive output control device A1, A3 and the main, passive input control device A2, A4 each should be switched to the position with the downshill 1132; at this time, the fluid of the active end device C can be output by the active fluid output end, and the active output channel C11 and the active output control device are actively output control device. A1 Fast Tract 1132, Sixth Pass E6, Passive Output Control Device A3 Fast Trail 1132, Passive Output Powers D11 and Passive fluid output end D1, flowing to the passive end device D; in addition, the fluid of the passive end device D may be output by the passive fluid input terminal D2, and the passive input channel D21, and the device 1132 of the passive output control device A4 1132 1132 1132 , Seventh -Pass E7, Active Input Control Device A2 Fast Trail 1132, Active Input Powers C21 and Active fluid input terminal C2, flowing to the active end device C; therefore, the flow system of the active end device C output conflicts with the fluid output of the passive end device D. The pressure of the fluid, the pressure of the fluid output of the active end device C can overcome the pressure of the fluid output of the passive end device D, so that the fluid flows from the active end device C to the passive end device D, so that the passive end device D is operated reverse, and then flow back to the active end device C. The pressure of the body, the passive end device The pressure of the fluid output by D can overcome the pressure of the fluid output by the active end device C, so that the fluid flows from the passive end device D to the active end device C, makes the active end device C reverse operation, and then flows back to the passive end device D.

In practical application of this kind of combination, the active end device C (or passive end device D) with higher fluid pressure is a force applying device (which can be regarded as a mechanism that provides a positive driving force, such as: an automobile engine), and the passive end device D (or active end device C) with a smaller fluid pressure is a force receiving device (which can be regarded as a transmission device that receives power); The passive end device D (or active end device C) operates in reverse, and its function is similar (vehicle gearbox) in the reverse gear (R) state.

Referring to Fig. 17, it can be seen that the sixth application state embodiment of the present invention is a combined application form similar to the aforementioned fifth embodiment, which is connected to a load device L on the seventh path E7 of the embodiment shown in Fig. 16 in the above-mentioned basic structure.

The above-mentioned combination structure is mainly applied to the two main and passive end devices C and D, both of which are force-applying devices. When the first diversion ports 26 of the switching elements 2 of the main and passive output control devices A1 and A3 and the main and passive input control devices A2 and A4 are all switched to the positions conducting with the respective flow channels 1132, the main and passive output control devices A1 and A3 are integrated with the main and passive input control devices A2 and A4 and the load device L to form a fluid circuit; Among them, the driving force output by the load device L may be the remaining driving force after subtracting the output driving forces of the two main and passive end devices C and D.

When the driving force output by the active end device C is greater than the driving force output by the passive end device D, the driving force output by the active end device C can overcome the driving force (or static resistance) output by the passive end device D. At this time, the running direction of the load device L is the same as that of the active end device C; And if the driving force output by the passive device D is greater than the driving force output by the active device C, the driving force provided by the passive device D overcomes the driving force output by the active device C, and the running direction of the load device L is the same as that of the passive device D.

In actual application, the active end device C (or passive end device D) with higher fluid pressure can be regarded as a mechanism that provides a forward driving force (such as an automobile engine), and the passive end device D (or active end device C) with a smaller fluid pressure can be regarded as a mechanism that provides a reverse driving force (such as: a geared motor (generator) or a deceleration power generation device), and the load device L is a transmission device that receives power (such as: a gearbox); The reverse resistance generated by the passive end device D (or the active end device C) drives the load device L to continue to operate. Its function is similar to that of a car engine (forward) connected to a deceleration motor (generator) to run (reverse resistance), and to slow down the speed of the drive transmission (gearbox).

In actual application, the load device L can also be arranged on the sixth channel E6 connecting the master and passive output control devices A1 and A3, so as to achieve the same effect of being driven by the master and slave end devices C and D.

Based on the above, the guiding control device for fluid transmission and its application system of the present invention can indeed reduce the phenomenon of sudden increase or decrease of fluid pressure during the switching process. It has a wide range of applications and is indeed a novel and progressive invention. An application for an invention patent is filed according to law; within the scope of the patent application.
