Working procedure of the present utility model is:
At first oil-feed: at first in oil conservator, fill with oil by outside oil circuit, drive oil-feed by-pass cock 8, make and be in connected state between the filler opening of the oil outlet of oil conservator and active chamber 6 (piston that is oil-feed by-pass cock 8 is opened the first through hole 14-3 of protecgulum assemblying body 14, the second through hole 14-4 is blocked), drive drain cock 9, make between the oil outlet of oil conservator 7 and active chamber 6 to be in closed condition.(hydraulic oil in the oil conservator enters the second groove 12-4 of protecgulum 12 from the oil conservator second oil outlet 12-9 to send hydraulic oil to the oil-feed oil duct by built-in gear pump, enter the third through-hole 14-5 of protecgulum assemblying body 14 again, the internal piston, the first through hole 14-3, the oil-feed through hole 12-2 of protecgulum of protecgulum assemblying body 14, the oil-feed through hole 11-2 on the housing 11, the active chamber filler opening 11-3 that enter the oil-feed by-pass cock more successively enter in the active chamber), hydraulic oil directly enters in the active chamber by the filler opening of active chamber; Simultaneously, because transmission main shaft drives brake structure 3 rotations, the meeting of brake structure 3 produces suction hydraulic oil is sucked the active chamber from filler opening, fills oil in active chamber.Because gear pump with the transmission main shaft rotation, can quicken hydraulic oil and enter in the active chamber, can increase work efficiency and pressure always.Gear pump has that fuel delivery is stable, pressure is high and the advantage in working life.
Retarder is started working then, its working principle: wheel rotor and back wheel rotor rotation before transmission main shaft drives, its blade got rid of hydraulic oil on the blade at intermediate stator impeller two ends when preceding wheel rotor and back wheel rotor rotated, thereby the blade pass on the stator impeller is crossed the vortex generation counter-force of hydraulic oil and is acted on the blade of preceding wheel rotor and back wheel rotor, be subjected to the effect of a resistance distance when wheel rotor and back wheel rotor rotate promptly, reach the purpose that makes vehicle speed retarding.In the course of the work, by the control tap changer, can the Control work chamber in the pressure size; When the pressure in the active chamber is excessive, the hydraulic oil in the active chamber can be gushed a part and enter in the oil conservator by regulating tap changer, thereby reach purpose to the active chamber step-down.
Last oil return: after retarder work is finished, drive oil-feed by-pass cock 8, make between the filler opening of the oil outlet of oil conservator and active chamber 6 and be in closed condition, drive drain cock 9, make and be in open mode (piston that is oil-feed by-pass cock 8 is blocked the first through hole 14-3 of protecgulum assemblying body 14, and the second through hole 14-4 is opened) between the oil outlet of oil conservator 7 and active chamber 6.Hydraulic oil in active chamber oil outlet from active chamber under the effect of brake structure rotating force is constantly discharged, and the hydraulic oil of discharge finally enters in the oil conservator.Simultaneously, hydraulic oil in the oil conservator enters the second groove 12-4 of protecgulum 12 from the oil conservator second oil outlet 12-9, enter the third through-hole 14-5 of protecgulum assemblying body 14 again, the second through hole 14-4 that enters internal piston, the protecgulum assemblying body 14 of oil-feed by-pass cock 8 more successively refluxes and enters oil conservator, hydraulic oil circulates in oil conservator, helps heat radiation.Because gear pump with the transmission main shaft rotation, can quicken the discharge of hydraulic oil, increases work efficiency always.After hydraulic oil in the active chamber was discharged fully, hydraulic oil was constantly circulating between oil conservator and outside oil duct under the drive of gear pump, helped accelerating heat radiation.
