Embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by an embodiment.
As shown in Figure 1, the utility model is a kind of liquid coupling reverse-cutting transmission case, and it comprises fluid coupling 1, is provided with quick clutch mechanism between the active chamber of described fluid coupling 1 and the fuel tank 16.Clutch mechanism is the quick oil extraction pipeline that is arranged between fluid coupling 1 active chamber and the fuel tank 16 fast; Clutch mechanism comprises the outer cover 14 of fixedlying connected with the driving wheel of fluid coupling 1 fast, outer cover 14 is connected by oilhole 15 with the active chamber of fluid coupling 1, A/C 13 is installed in the outer cover 14, the opening direction of A/C 13 1 ends is met the next oily direction to the rotating working oil of outer cover 14 high speeds, A/C 13 is provided with one-way valve 2, the other end of A/C 13 is communicated with oil cooler 6, the oil outlet of oil cooler 6 is connected with ratio adjusting control valve filler opening 7, the oil outlet 17 of ratio adjusting control valve is communicated with the active chamber filler opening of fluid coupling 1, also be provided with bypass 9 on the ratio adjusting control valve 8, described bypass 9 is communicated with fuel tank 16; Fuel tank oil outlet place is provided with thick oil purifier 18, and the fuel tank oil outlet is connected with oil pump 11 by oil pipe, and oil pump 11 is connected with oil cooler 6 by oil pipe, and the oil pipe between oil cooler 6 and the oil pump 11 is provided with smart oil purifier 10; Be equipped with single gear reducing gear 3 behind the fluid coupling 1, fluid coupling output shaft 4 and single gear reducing gear output shaft 5 are arranged vertically.Single gear reducing gear 3 and fluid coupling 1 are positioned at same casing.
Can realize quick clutch response owing to adopted quick clutch mechanism; A/C is equivalent to an oil pump, send the working oil in the active chamber back to the coupler fuel tank through one-way valve, oil cooler, the by-pass hole of ratio adjusting control valve, when thereby the ratio adjusting control valve of being implemented in is closed, the working oil fast evacuation of coupler rotor chamber, realize quick clutch function; The ratio adjusting control valve of coupler rotor chamber filler opening place design and installation, by regulate this ratio adjusting control valve promptly can realize coupler " from, close " function, also can realize simultaneously step-less adjustment, realize step-less adjustment the coupler output speed to the active chamber filling amount; The rearmounted single gear reducing gear of coupler, output shaft has adopted vertical high-order arrangement, specifically can adopt and be higher than about the about 425mm of input shaft, being convenient to cardan shaft directly is connected with the slurry pump input shaft, coupler and the design of single gear reducing gear are in same casing, input shaft and output shaft switched in opposite, thereby be called " anti-railway carriage ".
The concrete working principle of the utility model is as follows:
When liquid coupling reverse-cutting transmission case is in " closing " with " speed governing " running state, pneumatic or electronic ratio adjusting control valve is in " opening " or " portion separately " state, and working oil enters active chamber through fuel tank, thick oil purifier, oil pump, smart oil purifier, oil cooler sub-unit, pneumatic or electronic ratio adjusting control valve oil outlet.Work as power engine, as diesel engine, drive 12 rotations of fluid coupling input shaft during rotation, fluid coupling input shaft 12 drives the pump impeller rotation of fluid coupling, drives oil pump 11 rotations simultaneously, and the working oil in the casing 16 is pumped into active chamber, the working procedure of fluid coupling belongs to prior art, repeat no more, the rotational speed of fluid coupling output shaft is determined that by the active chamber liquid filled ratio under 8 controls of ratio adjusting control valve final power is through rearmounted single gear reducing gear 3 outputs.
Though some working oil of this running state circulates along A/C 13, one-way valve 2, oil cooler 6, ratio adjusting control valve 8 and active chamber, though this cyclic process A/C 13 is in oil extraction, but the working oil of discharging finally flows to active chamber again, because of the volume of circulation loop is fixed, thereby whole process can not change the liquid filled ratio of active chamber; Final working oil is through nozzle flow oil sump tank 16, thereby finishes the whole circulation process.
When liquid coupling reverse-cutting transmission case be in " from " during running state, ratio adjusting control valve 8 is in " pass " state, the active chamber oil-feed is cut off.Working oil drains back to fuel tank 16 fast through A/C 13, one-way valve 2, oil cooler 6 and ratio adjusting control valve bypass 9 in the active chamber, thereby realizes quick clutch response.
The utility model can pass through existing techniques in realizing without the technical characteristics of describing, and does not repeat them here.Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
