Abstract
The utility model discloses the bearing lubrication circulatory system on a kind of hydrodynamic retarder, it comprises housing on hydrodynamic retarder and heat exchanger, housing is provided with working oil chamber and for bearings mounted mounting groove, working oil chamber is connected with mounting groove, the perisporium of working oil chamber is provided with the first oil outlet, the perisporium of mounting groove is provided with the first oil inlet hole, heat exchanger is provided with the second oil inlet hole and the second oil outlet, first oil outlet is connected with the second oil inlet hole by first passage, and the second oil outlet is connected with the first oil inlet hole by second channel.The utility model can be continuously bearing and provide lubrication.
Description
Technical field
The utility model relates to the bearing lubrication circulatory system on a kind of hydrodynamic retarder.
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, 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.
Hydrodynamic retarder is provided with transmission shaft, impeller of rotor is connected to carry out synchronous axial system by transmission shaft with the output shaft of automobile gearbox, and the bearing be provided with on hydrodynamic retarder for installing transmission shaft, bearings mounted mounting groove is communicated with the working oil chamber on housing, when hydrodynamic retarder works, it is bearing lubrication that hydraulic oil in working oil chamber can flow in mounting groove, but when hydrodynamic retarder does not work, hydraulic oil in working oil chamber just cannot provide lubrication for bearing, this just makes to need regularly to start hydrodynamic retarder for bearing provides lubrication, this hydrodynamic retarder is made to use inconvenience.
Model utility content
Technical problem to be solved in the utility model is, provide the circulatory system of the bearing lubrication on a kind of hydrodynamic retarder, it can be continuously bearing and provide lubrication.
For solving the problems of the technologies described above, the bearing lubrication circulatory system on the hydrodynamic retarder that the utility model provides, it comprises housing on hydrodynamic retarder and heat exchanger, housing is provided with working oil chamber and for bearings mounted mounting groove, working oil chamber is connected with mounting groove, the perisporium of working oil chamber is provided with the first oil outlet, the perisporium of mounting groove is provided with the first oil inlet hole, heat exchanger is provided with the second oil inlet hole and the second oil outlet, first oil outlet is connected with the second oil inlet hole by first passage, second oil outlet is connected with the first oil inlet hole by second channel.
After adopting above structure, the utility model compared with prior art, has following advantage:
In the utility model hydrodynamic retarder, hydraulic oil in working oil chamber is by the first oil outlet, first passage, second oil inlet hole enters into heat exchanger, after hydraulic oil cools in heat exchanger, hydraulic oil is by the second oil outlet, second channel, first oil inlet hole enters in mounting groove, for the bearing in mounting groove provides lubrication, then working oil chamber got back to by hydraulic oil, hydraulic oil circulates constantly for bearing provides lubrication with this, in hydrodynamic retarder work or when not working, hydraulic oil all can be continuously bearing and provide lubrication, just not needing regularly to start as in the state of the art hydrodynamic retarder for bearing provides lubrication, make this hydrodynamic retarder easy to use.
As improvement, the first described oil outlet is positioned at the top of working oil chamber.Make the first oil outlet and first passage easy to process.
Accompanying drawing explanation
Fig. 1 is the structural representation of housing;
Fig. 2 is the structural representation at another visual angle of housing;
Fig. 3 is the structural representation of heat exchanger.
Wherein, 1, housing; 2, heat exchanger; 201, the second oil inlet hole; 202, the second oil outlet; 3, working oil chamber; 301, the first oil outlet; 4, mounting groove; 401, the first oil inlet hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Shown in Fig. 1 ~ Fig. 3, the bearing lubrication circulatory system on the utility model hydrodynamic retarder comprises housing 1 on hydrodynamic retarder and heat exchanger 2, housing 1 is provided with working oil chamber 3 and for bearings mounted mounting groove 4, working oil chamber 3 is connected with mounting groove 4, the perisporium of working oil chamber 3 is provided with the first oil outlet 301, the perisporium of mounting groove 4 is provided with the first oil inlet hole 401, heat exchanger 2 is provided with the second oil inlet hole 201 and the second oil outlet 202, first oil outlet 301 is connected with the second oil inlet hole 201 by first passage, second oil outlet 202 is connected with the first oil inlet hole 401 by second channel, regardless of when this hydrodynamic retarder work does not still work, a part of hydraulic oil in working oil chamber 3 is all by the first oil outlet 301, first passage, second oil inlet hole 201 enters into heat exchanger 2, after hydraulic oil cools in heat exchanger 2, hydraulic oil is by the second oil outlet 202, second channel, first oil inlet hole 401 enters in mounting groove 4, for the bearing in mounting groove 4 provides lubrication, then working oil chamber 3 got back to by hydraulic oil, hydraulic oil circulates constantly for bearing provides lubrication with this.
The first described oil outlet 301 is positioned at the top of working oil chamber 3, and the first oil outlet 301 is processed more for convenience, makes first passage easy to process simultaneously.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
