As illustrated in fig. 2 and 3 a, the lubricating oil repairing oil circuit of hydro viscous variable speed drive 200 are as follows: point oil of driving shaft 1
Oil liquid in road 1d flows to direction valve 14 by aperture 43.Direction valve 14 controls oil liquid and is flowed to by oil duct hose 15 and aperture 41
Working oil chamber 28.When output speed declines suddenly, correspondingly the working oil pressure in working oil chamber 28 declines suddenly, therefore logical
Lubricating oil repairing is crossed to increase working oil pressure, to reduce gap between main driven friction and then increase active friction plate 6
Oil-shear power between driven friction 7 is final to keep output stabilization of speed to increase output revolving speed.

Lubricating oil between driving shaft 1 flows to automatic oil recharging device, avoids the waste of lubricating oil.
The working principle of automatic oil recharging device designed by the present invention are as follows: when output revolving speed increases suddenly, generates a wave
When dynamic, the oil in working oil chamber 28 flows out from damping hole 29.In addition, since device itself is there is also there is certain leakage, again
Because the variation of its pressure is smaller, so the output fluctuation of speed can be greatly reduced by damping hole 29.When output revolving speed reduce suddenly,
When generating a fluctuation, then decline suddenly occurs for pressure in working oil chamber 28, pressure jump can trigger pressure sensor 18 and
Electric signal is generated, electric signal passes through signal amplifier 16, signaling control unit 45, and the final direction valve 14 that controls is opened, fuel tank 12
Middle oil liquid outflow, is flowed in working oil chamber 28 by oil duct hose 33, oil duct hose 15 and aperture 41, so that working oil chamber 28
Interior oil liquid pressure reaches predetermined oil pressure, to achieve the purpose that stable output speed.
Herein it is noted that the rate of pressure change in the mutation such as available work oil pocket 28 of output speed is (single
Change value of pressure in the time of position) it indicates and differentiates.Such as default pressure is set in the microprocessor 451 of signaling control unit 45
Power pace of change, this preset pressure pace of change can be set according to different loads situation, it is meant that in the case of different loads
Hydro-viscous speed governing clutch export fluctuation of speed problem, can targetedly be set according to actual conditions.Signaling control unit 45
451 real-time monitoring working oil chamber 28 of microprocessor in pressure and calculate rate of pressure change.When monitoring working oil chamber 28
When interior pressure declines suddenly and reaches preset pressure pace of change, then it is believed that output speed reduces suddenly, microprocessor
451 sending control instruction control direction valves 14 are acted accordingly.When monitor in working oil chamber 28 pressure decline but not
When reaching preset pressure pace of change, show that hydro-viscous speed governing clutch is in normal speed regulation operating condition, working oil chamber pressure change is
Normal regulating is acted at this point, microprocessor 451 will not issue control instruction to direction valve 14, therefore will not be caused certainly
The mistake repairing movement of dynamic recharging oil device, the mistake for effectively preventing the slowly varying of control oil pressure and generating send out control electric signal.Into
One step, according to output fluctuation of speed problem of the hydro-viscous speed governing clutch under different application, signaling control unit 45
Microprocessor 451 can also correspondingly adjust repairing signal.Such as: it, can be with when exporting revolving speed decline acutely and amplitude is big
It exports electric signal and controls the quick repairing of direction valve 14, when the slack-off and amplitude of output revolving speed decline is smaller, electric signal can be exported
Direction valve 14 is controlled with corresponding speed repairing, until exporting stabilization of speed.Largely improve clutch
Output stability and accuracy.
In conclusion the embodiment of the present invention inside hydro-viscous speed governing clutch 200 by being arranged automatic oil recharging device, i.e., it is logical
