Background technique
Hydrodynamic retarder is a kind of auxiliary brake device for automobile, be mainly used in motorbus, urban public traffic vehicles, heavy truck and military vehicle, hydrodynamic retarder comprises housing and heat exchanger, housing have shoe cream room and working oil chamber, impeller of rotor and stator impeller is provided with in working oil chamber, the output shaft synchronous of impeller of rotor and automotive transmission case rotates, and in motion, impeller of rotor also can rotate automobile.During hydrodynamic retarder work, pressurized air enters shoe cream room, hydraulic oil in shoe cream room is compressed into the cavity between stator impeller and impeller of rotor, when hydrodynamic retarder is started working, impeller of rotor drives hydraulic oil to rotate about the axis, simultaneously, hydraulic oil moves along the direction blade of impeller of rotor and gets rid of to stator impeller, the blade of stator impeller produces reaction force to hydraulic oil, hydraulic oil outflow stator impeller goes back to impact rotor impeller again, so just form the resisting moment to impeller of rotor, thus realize the decelerating effect to vehicle.
Hydraulic oil circulation loop on current hydrodynamic retarder is only when hydrodynamic retarder works, and is constantly circulated by the hydraulic oil in working oil chamber, hydraulic oil is cooled, function singleness between working oil chamber and heat exchanger.
Summary of the invention
Technical problem to be solved by this invention is, provides the circulatory system of the hydraulic oil on a kind of hydrodynamic retarder, and it not only can make hydraulic oil cool, and constantly can also filter hydraulic oil.
For solving the problems of the technologies described above, the hydraulic oil circulatory system on hydrodynamic retarder provided by the invention, it comprises housing on hydrodynamic retarder and heat exchanger, housing is provided with working oil chamber, the perisporium of working oil chamber is provided with the first oil outlet and the first oil inlet hole, heat exchanger is provided with heat exchanger oil inlet hole and heat exchanger oil outlet, first oil outlet is connected with heat exchanger oil inlet hole by first passage, heat exchanger oil outlet is connected with the first oil inlet hole by second channel, first passage is provided with the first one-way valve, the perisporium of described working oil chamber is provided with the second oil outlet, second oil outlet is connected with heat exchanger oil inlet hole by third channel, heat exchanger oil outlet is connected with the first oil inlet hole by four-way, third channel is provided with filter screen and the second one-way valve.
After adopting above structure, the present invention compared with prior art, has following advantage:
When hydrodynamic retarder works, first one-way valve opens, hydraulic oil in working oil chamber is by the first oil outlet, first passage, heat exchanger oil inlet hole enters into heat exchanger, hydraulic oil is after heat exchanger cooling, hydraulic oil is by heat exchanger oil outlet, second channel, first oil inlet hole gets back to working oil chamber, circulate with this and hydraulic oil cooled, simultaneously, second one-way valve opens, a part of hydraulic oil in working oil chamber is by the second oil outlet, third channel, heat exchanger oil inlet hole enters heat exchanger, then heat exchanger oil outlet is passed through through overcooled hydraulic oil, four-way, first oil inlet hole gets back to working oil chamber, by the filter screen on third channel, hydraulic oil is constantly filtered, make the hydraulic oil circulatory system on this hydrodynamic retarder that hydraulic oil not only can be made to cool, constantly can also filter hydraulic oil, make hydraulic oil comparatively pure.
As preferably, described filter screen is fixed on the entrance point of the second one-way valve.Make filter screen fixing more for convenience.
