The utility model working principle process is as follows:
Sprocket wheel 3 and sprocket wheel 7 are normal coupled condition.During Vehicle Driving Cycle, when retarder is not worked, operating switch is in off state.Sprocket wheel 3 and sprocket wheel 7 dally, and now because electromagnetic gas valve 6 is not switched on, thereby clutch 25 do not engage, and line shaft 23 does not rotate, and water pump 20 and radiator fan 14 are not worked.When two-position three-way valve 15 is not switched on, pipeline 12 is off state (now pipeline 12 is UNICOM's state with pipeline 10) with pipeline 8.Now pipeline 12, two-position three-way valve 15, pipeline 10, working solution storage tank 9, pipeline 11, working solution heat radiator assembly 13, water pump 20 form heat-radiation loop.During water outlet four-way electromagnetic valve assembly 24 access failure power supply, one of them passage is normal open state (can open in addition its excess-three passage after switching on power).
When vehicle descent run need slow down and travel slowly, operation electric control switch, the entering water electromagnetic valve of opening (two-position three-way valve 15), now pipeline 12 and pipeline 8 are connected (now pipeline 12 is off state with pipeline 10).Open electromagnetic gas valve 6, pressurized gas enter Pneumatic mechanical type clutch 25 simultaneously, clutch combination, and sprocket wheel 7 drives line shaft 23 synchronous rotaries, by speed increaser 22, drives belt pulley 16 to rotate.By v belt 17, drive belt pulley 18 and fan 14 to rotate, fan 14 helps the working liquid body heat radiation in heat radiator assembly 13.By v belt 19, drive belt pulley 21 to rotate, belt pulley 21 drives water pump 20 to work. and the working solution pressurizeing by water pump is in the middle of piping 12 and pipeline 8 are injected into speed reducer 1 inner chamber of retarder.Because speed reducer 1 rotor shaft (being also speed reducer main shaft) and truck drive shaft directly connect and synchronize rotation with flange 2 and flange 4, epitrochanterian blade rotary is thrown to the blade surface on stator by working liquid body, thereby produced the resisting moment to truck drive shaft, made truck drive shaft reduce rotational speed and reached car deceleration.After Vehicle Speed subtracts and, by the passage of controlling four-way electromagnetic valve assembly 24, open quantity, can reach different slow effects.Passage unlatching quantity is more, and Vehicle Speed is lower.(now, the inner chamber of water pump 20, pipeline 12, pipeline 8, speed reducer 1, unidirectional liquid valve 27, pipeline 26, four-way electromagnetic valve assembly 24, pipeline 10, working solution storage tank 9, pipeline 11, working solution heat radiator assembly 13 form fluid loop).
When normal vehicle operation stops retarder work, close two-position three-way valve 15, pipeline 12 disconnects (now pipeline 12 and pipeline 10 UNICOMs) with pipeline 8, do not have liquid to flow into speed reducer 1 inner chamber.During its speed reducer 1 rotor blade rotation, working solution is extruded to inner chamber and do not refluxed from the unidirectional liquid valve 27 of water outlet flows out, inner chamber forms cavity, and blade does not have liquid to impact, thereby does not produce resisting moment, can not produce and slow down or slow effect.Now the electromagnetic gas valve 6 of pneumatic machinery clutch 25 remains connection, and clutch engages, line shaft rotation, and water pump 20 is still in work.Now working liquid body flows back to water pump 20 through pipeline 12, two-position three-way valve 15, pipeline 10, working solution storage tank 9, pipeline 11, heat radiator assembly 13, and retarder working liquid body enters radiating state.When working liquid body temperature drops to after predetermined state, close electromagnetic gas valve 6, clutch 25 is thrown off, and water pump quits work.
When vehicle, run at high speed and need during quick reduction of speed on smooth road, operation-control switch, directly selects suitable slow gear, and vehicle is with required retardation reduction of speed and do not produce impact phenomenon.
