[0002] AMT is a modification on the original basis of the mechanical gearbox (manual transmission), mainly changing the manual gear shifting operation part. It is an electromechanical and hydraulic integrated automatic transmission that combines the advantages of both AT (automatic) and MT (manual). AMT has the advantages of automatic shifting of hydraulic automatic transmission, and retains the advantages of high efficiency, low cost, simple structure and easy manufacturing of the original manual transmission gear transmission.
[0003] The clutch release bearing is a relatively important part in the automobile AMT system. The clutch release bearing in the existing general technology usually includes an inner ring, an outer ring, balls, and a retaining frame arranged between the outer ring and the inner ring and used to keep the balls stable. In order to make the clutch release bearing have a good dustproof effect, a dust cover is usually provided at the end of the clutch release bearing. In order to ensure that the bearing can be cooled smoothly and reduce friction resistance during rotation, it is usually necessary to add lubricating oil to the balls through the dust cover. The dust cover in the existing general technology is only provided with a refueling hole, but the lubricating oil may contain impurities. When a lot of debris enters between the outer ring and the inner ring, it will affect the normal activity of the balls, thereby affecting the normal use of the clutch release bearing.

[0033] In this embodiment, the top of the upper cover body 4 is provided with an arc-shaped installation groove 42, an oil storage groove 43 and a lower oil through groove 44 in order from top to bottom, and the widths of the arc-shaped installation groove 42, the oil storage groove 43 and the lower oil through groove 44 are successively reduced. The top of the upper cover body 4 is also provided with an oil filling hole (the oil filling hole is not shown in the figure), and the upper cover body 4 is provided with an oil filling plug 45 for closing the oil filling hole. The top of the upper cover body 4 is provided with a cover plate 6 that cooperates with the arc-shaped installation groove 42, and the oil storage groove 43 is provided with a filter plate 7 that cooperates with the oil storage groove 43 and is used to block the lower oil through groove 44. A disposable filter screen 71 is provided on the top of the filter plate 7. After opening the oil filling plug 45, lubricating oil can be added to the oil storage groove 43 through the oil filling hole. The filter plate 7 cooperates with the disposable filter screen 71 and plays a good filtering role on the lubricating oil, reducing the probability that the impurities contained in the lubricating oil enter between the outer ring 2 and the inner ring 1, which will affect the normal activity of the ball 3 after a long time, which is conducive to ensuring the normal use of the clutch release bearing. The disposable filter screen 71 is a disposable product and can be replaced after the upper cover body 4 is opened, eliminating the tedious operation of disassembling the filter plate 7 and cleaning it.
[0034] In order to enhance the stability of the disposable filter 71 during use, an inner arc pressure plate 61 and an outer arc pressure plate 62 are fixed to the bottom of the cover plate 6. The bottom surfaces of the inner arc pressure plate 61 and the outer arc pressure plate 62 are both fitted with the top of the disposable filter 71. The inner surface of the inner arc pressure plate 61 is fitted with the arc surface of the oil storage tank 43 on the side close to the inner ring 1, and the outer surface of the outer arc pressure plate 62 is fitted with the arc surface of the oil storage tank 43 on the side away from the inner ring 1.
