Description
Technical field
The present invention relates to a kind of hydrodynamic retarder for heavy-duty car, specifically is a kind of hydrodynamic retarder stator impeller.
Background technique
Hydrodynamic retarder is a kind of complemental brake system that is applicable to the military products car, and in present hydrodynamic retarder, impeller of rotor directly is connected with rotatingshaft; The stator impeller mainly comprises impeller body and blade, and its blade is evenly distributed on the inner side surface of impeller body.When automobile needs braking deceleration, open the switch of control hydrodynamic retarder, the hydraulic oil that rotor spins out enters in the stator impeller blade, form eddy current in the cavity between blade, react on rotor, give bigger resistance of rotor, make engine retard.Adopt the hydrodynamic retarder stator impeller of this kind structure, following deficiency is arranged: when hydraulic retarder quits work, working space between rotor and the stator is full of air, because impeller of rotor is driven all the time by rotatingshaft and is rotating, form one air-flow, air comes out to enter working space between the stator vane from rotor, forms eddy current, also can produce bigger resistance to rotor, increase the working loss of the rotatingshaft that is being connected with impeller of rotor.
Summary of the invention
Technical problem to be solved by this invention is: overcome the defective of above prior art, a kind of hydrodynamic retarder stator impeller is provided, can effectively reduce the resistance that rotor is subjected to when hydrodynamic retarder quits work, and then reduce the working loss of rotatingshaft.
The technical solution used in the present invention is: a kind of hydrodynamic retarder stator impeller is provided, it comprises impeller body, blade and disturbing flow device, described blade is distributed in the inner side surface of impeller body, described disturbing flow device comprises the elastic telescopic body, elastic telescopicing rod and flow-disturbing dish, described elastic telescopicing rod is slidingly fitted in the elastic telescopic body, described flow-disturbing dish is installed on the free end of elastic telescopicing rod, in the cavity of described disturbing flow device between two blades, described elastic telescopic body is fixed on the impeller body, and the inboard of the cavity between two blades, the outside of the cavity of described flow-disturbing dish between two blades.
After adopting above structure, hydrodynamic retarder stator impeller of the present invention compared with prior art has the following advantages: be provided with disturbing flow device between two blades of stator impeller, when hydrodynamic retarder is worked, working space between rotor and the stator is full of hydraulic oil, hydraulic oil accelerates to enter the stator impeller by impeller of rotor, hydraulic oil pushes back original position with the flow-disturbing dish against elastic force, make hydraulic oil between the blade of stator impeller, form eddy current, when hydraulic oil comes out from the stator impeller, rotor is produced bigger resistance, thereby guarantee that hydrodynamic retarder normally carries out work; When hydrodynamic retarder is closed, impeller of rotor is driven by rotatingshaft and continues to rotate, working space between rotor and the stator is full of air, air accelerates to enter the stator impeller by impeller of rotor, because the inhibition of disturbing flow device, can not form air swirl, the resistance to rotor when air comes out from the stator impeller obviously reduces, thus the loss of the rotatingshaft that the minimizing rotor connects.
As improvement, the quantity of described disturbing flow device is 5～15, lays respectively in the cavity between corresponding two blades, to improve the whole utilization efficiency of stator impeller.
As improvement, the optimal number of described disturbing flow device is 7～11.
As improvement, described elastic telescopic body comprises support tube, sleeve pipe, spring and locking member, the right-hand member of described support tube is connected in the opening of the left side of sleeve pipe, described spring is placed in the chamber of sleeve pipe, and the left end of spring is enclosed within the outside of support tube right-hand member, the right openings place that described locking member is arranged on sleeve pipe guarantees the disturbing flow device proper functioning.
