Abstract
The invention discloses a pressure stabilizer used for a hydraulic retarder. The pressure stabilizer comprises a pressure stabilizing cavity (2) arranged on a housing (1) and a pressure stabilizing valve (3) matched with the pressure sterilizing cavity (2), wherein one end of the pressure stabilizing cavity (2) communicates with an oil storage cavity (5) through a gas inlet (4); and the other end of the pressure stabilizing cavity (2) communicates with atmosphere through a gas outlet (6). The invention provides the pressure stabilizer, which can ensure stable gas pressure in the oil storage cavity to ensure stable oil amount in a working oil cavity and to further ensure stable deceleration performance of the hydraulic retarder, used for the hydraulic retarder.
Description
Technical field
The present invention relates to Retarder technical field, be specifically related to a kind of stable-pressure device for Retarder。
Background technology
Retarder is a kind of auxiliary brake device for automobile, it is mainly used in motorbus, urban public traffic vehicles, heavy truck, special purpose vehicle and military vehicle, Retarder includes heat exchanger, rotor, stator and housing, housing has shoe cream room and working chamber, rotor and car transmissions link together, in motion, rotor also can rotate automobile。During Retarder work, proportional solenoid valve control compression air enters shoe cream room, the oil pressure in shoe cream room is entered the working chamber between Retarder stator and rotor, when Retarder is started working, rotor drives fluid to rotate about the axis, meanwhile, fluid moves along rotor blade direction, gets rid of to stator, fluid is produced counteracting force by stator vane, fluid outflow stator goes back to impact rotor again, thus forms the moment of resistance eddy current to rotor, thus realizing the decelerating effect to vehicle。
During Retarder work, owing to the amount of proportional solenoid valve control compression air entrance shoe cream room is difficult to accurate control so that shoe cream room internal gas pressure is not sufficiently stable, and causes that in working oil chamber, oil mass is unstable, so that the deceleration stability of Retarder declines。
Summary of the invention
The technical problem to be solved is: shoe cream room internal gas pressure is stable to provide one can guarantee that, thus ensureing that in working oil chamber, oil mass is stable, is further ensured that the stable-pressure device for Retarder that Retarder decelerability is stable。
This invention address that the technical scheme that the problems referred to above adopt is: a kind of stable-pressure device for Retarder, it includes the pressure stabilizing cavity being located on housing and the pressure maintaining valve coordinated with pressure stabilizing cavity, and described pressure stabilizing cavity one end connects the other end by gas outlet and atmosphere by air inlet with shoe cream room。
Compared with prior art, it is an advantage of the current invention that: housing sets stable-pressure device, after oil pressure in shoe cream room is entered working chamber by gas passing ratio electromagnetic valve control entrance shoe cream room, proportional solenoid valve control reduces gas inlet, the air-stable of a part is discharged housing by pressure maintaining valve constantly, making shoe cream room internal gas pressure reach dynamic equilibrium, thus ensureing that in working oil chamber, oil mass is stable, being further ensured that Retarder decelerability is stable。
As a modification of the present invention, body that described pressure maintaining valve includes being provided with cavity and opening down setting and for covering the Intake Cover of cavity, described Intake Cover is provided with the inlet channel for making air inlet connect with cavity, described body is provided with the outlet passageway for making cavity connect with gas outlet, described cavity is interior and is provided with voltage stabilizing ball between inlet channel and outlet passageway, by described improvement, oil storage intracavity gas enters cavity by inlet channel, outlet passageway is entered by the gap between voltage stabilizing ball and cavity after raising voltage stabilizing ball, finally it is discharged outside to air, gas discharge amount is by clearance control between voltage stabilizing ball and cavity, gas discharge amount controls accurately, ensure that shoe cream room internal gas pressure is stable, thus ensureing that in working oil chamber, oil mass is stable, it is further ensured that Retarder decelerability。
The one that also has as the present invention is improved, described housing is additionally provided with pressure-releasing chamber, described pressure-releasing chamber one end connects the other end with pressure stabilizing cavity and connects with gas outlet, by described improvement, after gas is discharged from outlet passageway, enter pressure-releasing chamber pressure release, be expelled to air again through gas outlet, buffering exhaust speed, reduces exhaust noise。
The one that also has as the present invention is improved, and described gas outlet is additionally provided with silencing apparatus, by described improvement, reduces exhaust noise further。
The one that also has as the present invention is improved, and described silencing apparatus is copper acoustic filter, and by described improvement, copper acoustic filter is possible to prevent corrosion, and ruggedness is strong。
