technical field

The invention relates to the technical field of hydraulic retarders, in particular to a front casing for a hydraulic retarder.

Background technique

In the process of using the traditional hydraulic retarder, the bearing strength of the front shell structure of the hydraulic retarder is relatively poor compared with the structure of the front shell structure, and when the hydraulic retarder is not working, the hydraulic retarder is not working. The medium oil in the working chamber of the front housing of the retarder will be reduced due to high temperature evaporation, and when the hydraulic retarder is not working, the bearing in the hydraulic retarder will be damaged. The phenomenon of damage will occur without effective lubrication, which is not conducive to the normal use of the entire hydraulic retarder. To this end, we propose a front housing for a hydrodynamic retarder.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inside", " The orientation or positional relationship indicated by "outside" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, so as to The specific orientation configuration and operation are therefore not to be construed as limitations of the present invention.

1-4, a front casing for a hydraulic retarder includes a casing 1, the front end of the casing 1 is provided with a bearing installation area 3 and an oil seal installation area 4, and the front end of the casing 1 is provided with a bearing installation area 3 and an oil seal installation area 4. Lubrication zone 5, a working cavity 101 is formed inside the rear end of the housing 1, and a four-fifth ring is provided on the outer side of the rear end of the housing 1 is provided with a lubrication channel ring 2, and a lubrication channel is provided on the four-fifth of the ring A plurality of bolt connection holes 6 and pin shaft connection holes 7 are distributed on the ring 2 , and a lubrication channel 8 is provided on four-fifths of the ring 2 .

The bearing installation area 3 is used to install the bearing; the oil seal installation area 4 is used to install the oil seal; the lubrication area 5 is bell-shaped, and the big end of the lubrication area 5 is upward; the housing 1 and the four-fifths ring 2 are integrated structure.

Working principle and advantages: in the process of installation and assembly of the present invention, the rear end of the casing 1 is connected with the middle casing and the rear casing of the hydraulic retarder to be assembled, and the hydraulic retarder is formed, and it is a hydraulic retarder. The casing 1 is connected with the middle casing of the hydraulic retarder through the four-fifths ring 2. At this time, the bolt connection holes 6 and the pin shaft connection holes 7 on the four-fifths of the ring 2 are set so that the entire front The casing can be connected to the casing in the hydraulic retarder through bolts and pins. The front end of the casing 1 is connected to the transmission. At this time, the output shaft of the transmission is inserted into the front casing. Inside, a bearing is installed between the bearing installation area 3 of the housing 1 and the output shaft of the transmission, and an oil seal is installed between the oil seal installation area 4 of the housing 1 and the output shaft of the transmission. The setting of the oil seal realizes the hydraulic retarder. The seal between the high pressure and the low pressure of the transmission can lubricate the bearings in the bearing installation area 3 and the oil seal in the oil seal installation area 4 through the oil in the lubricating area 5, and the big end of the lubricating area 5 is connected to the hydraulic pressure. The middle casings of the retarder communicate with each other, and along with the connection between the front casing and the middle casing of the hydraulic retarder, a working chamber can be formed between the stator in the hydraulic retarder and the working chamber 101 at this time. , During the working process of the hydraulic retarder, the setting of the four-fifths ring 2 enhances the structural strength of the entire front casing and enhances the bearing capacity of the entire front casing to adapt to greater torque; the lubrication channel 8 is connected to the hydraulic The interface of the middle casing of the retarder is connected. When the hydraulic retarder is not working, the rotor of the hydraulic retarder in the working chamber 101 rotates at a high speed, so the corresponding bearing inward of the hydraulic retarder will also rotate at a high speed. Rotation, for the high-speed rotating bearing, there is some medium oil in the working chamber 101 at this time, the medium oil enters the middle casing of the hydraulic retarder through the lubrication channel 8, and then enters the rear casing of the hydraulic retarder, and It further enters the heat exchanger of the rear shell, and mixes and cools with the medium oil in the heat exchanger. The cooled medium oil enters the middle shell of the hydraulic retarder, and is then passed by the hydraulic retarder. The oil passage of the middle casing enters the working chamber 101 and circulates again. Some medium oil in the working chamber 101 will not be reduced due to high evaporation during the circulation process, and will also lubricate the bearings, which is beneficial to To ensure the service life of the bearing in the hydraulic retarder, it is beneficial to ensure the service life of the entire hydraulic retarder. Therefore, the entire front housing is conducive to the assembly and use of the hydraulic retarder, thereby making the entire The front casing is favorable for popularization and use.
