The specific implementation process is as follows:
when lubricating the bearing of the hydrodynamic retarder, the following three modes are adopted:
the first method is as follows: as shown in fig. 2, the middle housing 11 and the rear housing 18 are in a vertical state when the hydrodynamic retarder is installed. When the hydrodynamic retarder is not in operation, under the action of gravity, oil in the lubricating oil storage chamber 19 enters the first oil hole 24 through the opening cavity 21, the small hole 17, the oil opening hole 15 and the oil inlet hole in the protruding cylinder 12, and then the oil enters the working cavity 26 to lubricate a bearing in the working cavity 26.
The second method comprises the following steps: as shown in fig. 2, the middle housing 11 and the rear housing 18 are in a vertical state when the hydrodynamic retarder is installed. When the hydraulic retarder needs to work, sufficient gas is filled into the oil storage chamber through the automobile gas circuit system and the electromagnetic proportional valve, so that the air pressure in the oil storage chamber is increased, oil in the oil storage chamber enters the lubricating oil storage chamber 19, and simultaneously enters the working chamber 26 through the second oil hole 25, the oil rotates along with the transmission shaft inside the working chamber 26, the oil flowing into the working chamber 26 is driven to rotate around the shaft and impacts the stator according to the motion track of the blades, the reaction force generated by the oil impacting the blades of the stator can prevent the rotor from rotating, so that the transmission shaft is prevented from rotating, the braking torque is generated to achieve the speed reduction effect, the oil lubricates the bearing, and the hydraulic retarder can be lubricated and work at work speed when working.
The third method comprises the following steps: as shown in fig. 2, the middle housing 11 and the rear housing 18 are in a vertical state when the hydrodynamic retarder is installed. When the vehicle runs or the lubricating oil is reduced to influence the self-running of the lubricating oil, an electromagnetic proportional valve can be arranged, the oil reservoir is pressurized in pulses, and because the lubricating oil reservoir 19 is at a lower level than the oil reservoir (as shown in the dotted line position of fig. 1, the dotted line on the left is a low level of oil, the dotted line on the right is a high level of oil, and the oil fills this region all the time), the lubricating oil reservoir 19, which is in a smaller space, is preferentially pressurized to force oil into the working chamber 26, the upper part of the oil storage chamber still has a larger space, the increased air pressure can only cause the oil level of the oil storage chamber to rise upwards by a certain amount, the oil cannot be injected into the working chamber 26, the retarder is not therefore active and produces torque, so that the air pressure value can be simply understood as the air pressure value set for lubrication alone, the lubricating frequency can be independently controlled through the electromagnetic proportional valve, so that the bearing can be lubricated under the condition that the hydraulic retarder does not work in a targeted mode.
The lubricating oil reflux mode is as follows: after the bearing is lubricated by the oil in the working chamber 26, the oil enters the oil return chamber 35 through the oil return hole 31 and the oil return column 32, so as to achieve the purpose of recycling the liquid oil.
Of course, the oil in the oil return chamber 35 can be cooled by the heat exchanger of its own component, and the heat exchanger is connected with the water circulation system of the automobile to dissipate heat, so as to achieve the purpose of recycling the oil.
In the description herein, reference to the description of the terms "preferred embodiment," "one embodiment," "some embodiments," "an example," "a specific example" or "some examples" or the like means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
