Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is further illustrated.Following embodiment makes a more detailed description the utility model, but it does not limit scope of the present utility model.Based on the present embodiment, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The electronic control unit ECU that truck of the present utility model mid-tandem hydrodynamic retarding device comprises hydrodynamic retarder 2 and is arranged in operator's compartment.
Fig. 1 is the arrangement structure figure of mid-tandem hydrodynamic retarder of the present utility model on vehicle driveline.Fig. 2 is the schematic diagram of the forward and backward link of mid-tandem hydrodynamic retarder of the present utility model on vehicle.Fig. 3 is the cutaway view of mid-tandem hydrodynamic retarder of the present utility model.
As shown in Figure 1, mid-tandem hydrodynamic retarder 2 of the present utility model is arranged between engine assembly 1 and transmission assembly 3.Particularly, as shown in Figure 2, mid-tandem hydrodynamic retarder 2 is arranged in the annular space between engine flywheel 4 and power-transfer clutch 5, and entirety is structural arrangement ringwise.
As shown in Figure 3, mid-tandem hydrodynamic retarder 2 of the present utility model comprises: rotor 7, stator 6, oil storage chamber housing 9, oil duct housing 10, H Exch 12, apportioning valve 11 and retarder flywheel 13 etc., take full advantage of the annular space between engine flywheel 4 and power-transfer clutch 5.By above-mentioned component height being integrated in one, rely on the towing astern of wheel during car retardation, drive wheel semiaxis is considered as moment input shaft, retarder center shaft is arrived through main reduction gear, transmission shaft, output shaft of gear-box, transmission input shaft, and then offset with the resisting moment that retarder operating fluid reacts on center shaft, be that heat energy distributes by the kinetic transformation in transmission process.
Wherein, rotor 7 one end by Flange joint on engine flywheel 4, the other end by Flange joint on retarder flywheel 13; Oil duct housing 10 one end is connected with stator 6 periphery bolt, and the other end is connected with oil storage chamber housing 9 periphery bolt; H Exch 12 is arranged on the annular periphery of hydrodynamic retarder 2, inside and oil storage chamber housing 9 are by oil duct (not shown) intercommunication, be provided with temperature sensor (not shown) in oil duct, it is inner that temperature sensor thermocouple inserts oil duct, and output signal line is external.Cooling water expansion tank in H Exch 12 is from engine-cooling system, and H Exch 12 front end is connected with the housing perimeter bolt of engine flywheel 4, and rear end is connected with the housing perimeter bolt of power-transfer clutch 5; Apportioning valve 11 is arranged on H Exch 12 upper end, built-in pressure sensor (not shown).
Rotor 7, stator 6 form airtight epitrochoidal chamber with oil storage chamber housing 9.When hydrodynamic retarder 2 works, hydraulic oil flowing in working chamber cycle circle forms slow moment of torsion; Under differential pressure action, hydraulic oil enters H Exch 12 through epitrochoidal chamber, oil storage chamber housing 9 and completes counter-flow after interchange of heat, sets up heat balance.Pressure reduction produces in epitrochoidal chamber, and rotor 7 blade outer rim place has oil outlet, and hydraulic oil flow velocity is fast herein, pressure is high, and inner edge place has return opening, and flow velocity is slow herein, pressure is low, and then forms pressure reduction going out, between return opening, impels hydraulic oil to circulate.
