Abstract:
The present invention provides a movement gear control device between an active device and a passive device of a vehicle. First, second, third and fourth control portions are provided in a main body, the control portions each are provided with a main flow channel; first, second, third and fourth switching members of a switching assembly are assembled in the main flow channels, respectively, the peripheral sides of the main flow channels are in communication with a plurality of branch flow channels; the main flow channels of the first and second control portions are in communication with a passage for outputting and inputting fluid of an active-end device, and the main flow channels of the third and fourth control portions are in communication with a passage for inputting and outputting fluid of a passive-end device; at least some of the branch flow channels of each of the control portions are in communication with each other, and the switching members are provided with lower flow guide ports in indirect communication with the main flow channels, respectively. When the switching members are operated by an external force, the lower flow guide ports can be selectively in communication with the branch flow channels, so as to form a plurality of different fluid transmission paths in the main body, thereby generating different movement gear controls between the active-end device and the passive-end device.
