Abstract
The utility model discloses a hydraulic retarber oil bath structure, including the oil bath shell, the upper end and the lower extreme of oil bath shell assemble oil bath shell upper cover and oil bath shell lower cover respectively, cover on the oil bath shell and offered inlet channel, be equipped with a plurality of hexagon heads hollow eye bolt of gas in the horizontal direction gets into the oil bath shell who makes in the oil bath shell upper cover in the inlet channel. The utility model discloses a hollow eye bolt of installation hexagon head on oil bath shell upper cover inlet channel to this changes the oil bath airflow direction that admits air, steady air current. Through experimental verification, this design can avoid the oil bath to aerify the in -process fluid spurging and the phenomenon of splashing effectively, guarantees that inner surface of the cover does not have fluid on the oil bath shell to adhere to, eliminates the retarber silencer oil spout phenomenon that from this arouses, ensures the normal work of retarber and the correct diagnosis of trouble.
Description
[technical field]
The utility model belongs to automobile retarder technical field, relates to a kind of hydrodynamic retarder, especially a kind of hydrodynamic retarder oil sump structure.
[background technique]
The raising that can require vehicle safety along with user and the policy support of country, hydrodynamic retarder just progressively becomes car load standard complemental brake system.Hydrodynamic retarder take fluid as the machinery of working medium and energy carrier.During hydrodynamic retarder work, control valve upon the reception of control signals, vehicle-mounted source of the gas is depressurized to setting pressure state, gas after step-down is vertically filled with above oil sump shell cavity via the gas-entered passageway in oil sump shell upper cover, by work fluid by filler opening one-way valve press-in hydrodynamic retarder active chamber, along with the rotation of retarder rotor realizes retarder brake.Vertically enter into oil sump cavity directly impact fluid surface because traditional retarder oil sump is designed to gas by oil sump shell upper cover, when gas pressure is larger, easily produces fluid foam and splash phenomena, fluid is attached on oil sump shell upper interior surface.When retarder is deactivated, because gas differential pressure inside and outside retarder is comparatively large, the gas of fluid of carrying under one's arms returns from oil sump shell upper cover gas-entered passageway fast and discharges through retarder exhaust passage, and then causes the oil spout of retarder silencing apparatus.
[model utility content]
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, a kind of hydrodynamic retarder oil sump structure is provided, this retarder oil sump structure is on the basis of traditional oils pool structure, oil sump charge air flow direction is changed by covering the hollow eye bolt of assembling hexagon head on oil sump shell, steady charge air flow, and then avoid gas to the direct impact of fluid.
For achieving the above object, the utility model is achieved by the following technical solutions:
A kind of hydrodynamic retarder oil sump structure, comprise oil sump shell, the top and bottom of oil sump shell assemble oil sump shell upper cover and oil sump shell lower cover respectively; Oil sump shell covers and offers gas-entered passageway, be equipped with in gas-entered passageway and make the gas in oil sump shell upper cover enter the hollow eye bolt of some hexagon heads in oil sump shell through substantially horizontal.
The utility model further improves and is:
Described oil sump shell covers and offers two auxiliary holes, and sealed by the first tapered plug and the second tapered plug.
Described first tapered plug is vertically arranged, and the second tapered plug is horizontally disposed with.
Described oil sump shell covers and also offers tank filler sleeve, oil stifled cooperation with seal washer is assembled in tank filler sleeve.
Described oil blocks assembling O-ring seals, is sealed stifled for oil by O-ring seals with oil sump shell upper cover.
Described O-ring seals is assemblied in the O shape ring recess offered in the stifled outside of oil.
At least 3 hollow eye bolts of hexagon head are equipped with in described gas-entered passageway.
Compared with prior art, the utility model has following beneficial effect:
The utility model, by installing the hollow eye bolt of hexagon head on oil sump shell upper cover gas-entered passageway, changes oil sump charge air flow direction with this, smooth air.Through experimental verification; this design can avoid fluid in oil sump gas replenishment process to produce foam and splash phenomena effectively; ensure that oil sump shell upper interior surface adheres to without fluid, eliminate the retarder silencing apparatus fuel injection event caused thus, guarantee the normal work of retarder and the correct diagnosis of fault.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model retarder oil sump;
Fig. 2 is the structural representation of the utility model retarder oil sump shell upper cover.
Wherein: 1 is the first tapered plug; 2 is oil sump shell upper cover; 3 is the hollow eye bolt of hexagon head; 4 is seal washer; 5 is that oil is stifled; 6 is O-ring seals; 7 is the second tapered plug; 8 is oil sump shell; 9 is oil sump shell lower cover.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 and Fig. 2, Fig. 1 shows the flow direction of oil sump inner fluid in gas replenishment process, and Fig. 2 shows the flow direction of gas in oil sump shell upper cover in gas replenishment process.The utility model is stifled 5 by the first tapered plug 1, oil sump shell upper cover 2, the hollow eye bolt 3 of hexagon head, seal washer 4, oil, O-ring seals 6, second tapered plug 7, oil sump shell 8, oil sump shell lower cover 9 etc. form.The hollow eye bolt 3 of hexagon head is assembled in the gas-entered passageway of oil sump shell upper cover 2, and the gas in oil sump shell upper cover 2 is entered in oil sump shell 8 through substantially horizontal.Oil sump shell 8 respectively with oil sump shell upper cover 2 and oil sump shell lower cover 9 assembly connection.Two auxiliary holes on oil sump shell upper cover 2 are sealed by assembling first tapered plug 1 and the second tapered plug 7.Oil stifled 5 and seal washer 4 cooperation are assembled in the tank filler sleeve on oil sump shell upper cover 2, have O shape ring recess outside oil stifled 5, assemble by blocking up at oil on 5 the sealing that O-ring seals 6 carries out oil stifled 5 and oil sump shell upper cover 2.
Consider and change oil sump charge air flow direction to the impact of hydrodynamic retarder braking response speed, the mode verified by experiment determines the position degree in the center bore of the hollow eye bolt 3 of hexagon head, side opening aperture, side opening quantity and assembling rear side hole, and detailed features can adjust in actual use according to demand.
During assembling, first hollow for hexagon head eye bolt 3 is loaded in oil sump shell upper cover 2, the hollow eye bolt bottom of hexagon head is a little less than oil sump shell upper cover 2 gas-entered passageway horizontal center line axis to select screw-down torque to ensure, after oil sump shell 8 and oil sump shell lower cover 9 have assembled, again oil sump shell upper cover 2 and oil sump shell 8 are assembled, use the first tapered plug 1 and the second tapered plug 7 to seal processing technology hole.The O shape ring recess blocking up 5 at oil loads O-ring seals 6, and fitted seal packing ring 4 and oil sump shell upper cover 2 complete assembling afterwards.
Above content is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technological scheme basis is done, within the protection domain all falling into the utility model claims.
