Description
Technical field
The present invention relates to the hydraulic oil blood circulation on a kind of 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 and military vehicle, Retarder includes housing and heat exchanger, there is on housing shoe cream room and working oil chamber, impeller of rotor and stator impeller it 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 Retarder work, compressed air enters shoe cream room, the cavity that hydraulic oil in shoe cream room is pressed between stator impeller and impeller of rotor, when 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 counteracting force to hydraulic oil, hydraulic oil flows out stator impeller and goes back to impact rotor impeller again, thus form the moment of resistance to impeller of rotor, thus realize the decelerating effect to vehicle.
Hydraulic oil closed circuit on current Retarder is only when Retarder works, is constantly circulated by the hydraulic oil in working oil chamber, make hydraulic oil cool down, function singleness between working oil chamber and heat exchanger.
Summary of the invention
The technical problem to be solved is to provide the hydraulic oil blood circulation on a kind of Retarder, and it is possible not only to make hydraulic oil cool down, it is also possible to constantly filter hydraulic oil.
For solving above-mentioned technical problem, the hydraulic oil blood circulation on Retarder that the present invention provides, it includes the housing on Retarder and heat exchanger, working oil chamber it is provided with on housing, the first oil outlet and the first fuel feed hole it is provided with on the perisporium of working oil chamber, heat exchanger fuel feed hole and heat exchanger oil outlet it is provided with on heat exchanger, first oil outlet is connected with heat exchanger fuel feed hole by first passage, heat exchanger oil outlet is connected by second channel and the first fuel feed hole, the first check valve it is provided with on first passage, the second oil outlet it is provided with on the perisporium of described working oil chamber, second oil outlet is connected with heat exchanger fuel feed hole by third channel, heat exchanger oil outlet is connected with the first fuel feed hole by fourth lane, drainage screen and the second check valve it is provided with on third channel.
After using above structure, the present invention compared with prior art, has the advantage that
nullWhen Retarder works，First check valve is opened，Hydraulic oil in working oil chamber passes through the first oil outlet、First passage、Heat exchanger fuel feed hole enters into heat exchanger，Hydraulic oil is after heat exchanger cools down，Hydraulic oil passes through heat exchanger oil outlet、Second channel、First fuel feed hole returns to working oil chamber，Circulate with this and hydraulic oil is cooled down，Simultaneously，Second check valve is opened，A part of hydraulic oil in working oil chamber passes through the second oil outlet、Third channel、Heat exchanger fuel feed hole enters heat exchanger，It is then passed through the hydraulic oil of cooling by heat exchanger oil outlet、Fourth lane、First fuel feed hole returns to working oil chamber，By the drainage screen on third channel, hydraulic oil is constantly filtered，The hydraulic oil blood circulation on this Retarder is made to be possible not only to make hydraulic oil cool down，Hydraulic oil constantly can also be filtered，Make hydraulic oil the purest.
As preferably, described drainage screen is fixed on the entrance point of the second check valve.Drainage screen is fixed more convenient.
