[0012] Furthermore, a rotary shaft seal is provided between the inner wall of the annular end cover and the side wall of the rotating shaft for maintaining the sealing performance between the annular end cover and the rotating shaft.

[0013] By adopting the above technical solution, the rotary shaft seal is a conventional means of transmission sealing between the shaft and the hole. The setting of the rotary shaft seal increases the sealing performance between the annular end cover and the rotating shaft.

[0014] Furthermore, the annular end cover is composed of two semicircular ring plates evenly distributed about the axis of the outer ring, and a second bolt is provided through the semicircular ring plate to match the clearance of the semicircular ring plate, and the end of the second bolt is threadedly connected to the top of the outer ring.

[0015] By adopting the above technical solution, the annular end cover composed of two semicircular ring plates is convenient for the staff to install, disassemble and repair the components on the annular end cover in the later stage. The setting of the second bolt makes it convenient for the staff to install and disassemble the two semicircular ring plates in the later stage.

[0016] Furthermore, a receiving hole for receiving the head of the second bolt is provided on the top of the annular end cover.

[0017] By adopting the above technical solution and setting the accommodating hole, the aesthetics of the bearing is improved.

[0018] Furthermore, a cross rod is fixed on the top of the sealing cover.

[0019] By adopting the above technical solution and setting the cross rod, it is convenient for the staff to open or close the sealing cover.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, the annular end cover plays a good role in blocking dust and other debris during the use of the clutch release bearing, reducing the probability that dust, debris and other debris enter between the outer ring and the inner ring and affect the normal rotation of the ball.

[0030] The annular end cover 5 is arranged on the top of the outer ring 1. The annular end cover 5 plays a good role in blocking dust and other debris during the use of the clutch release bearing, reducing the probability that dust, debris and other debris enter between the outer ring 1 and the inner ring 2 and affect the normal rotation of the ball 3. An oil storage tank 51 is arranged on the annular end cover 5, and an oil outlet hole 511 for adding oil between the outer ring 1 and the inner ring 2 is arranged on the inner bottom wall of the oil storage tank 51. A cover plate 52 for shielding the oil storage tank 51 is arranged at a position corresponding to the oil storage tank 51 on the top of the annular end cover 5, and an oil filling hole 521 is arranged through the top of the cover plate 52. A sealing cover 522 that cooperates with and seals the oil filling hole 521 is arranged on the top of the cover plate 52. A cross rod 5221 is fixed on the top of the sealing cover 522. The setting of the cross rod 5221 makes it convenient for the staff to open or close the sealing cover 522. The cover plate 52 is provided with a first bolt 523 which is loosely matched with the cover plate 52, and the lower end of the first bolt 523 is threadedly connected with the top of the annular end cover 5. In this embodiment, the annular end cover 5 is composed of two semicircular annular plates 524 which are evenly distributed about the axis of the outer ring 1, and the semicircular annular plates 524 are provided with a second bolt 5241 which is loosely matched with the semicircular annular plates 524, and the end of the second bolt 5241 is threadedly connected with the top of the outer ring 1. The top of the annular end cover 5 is provided with a receiving hole 525 for receiving the head of the second bolt 5241. The provision of the receiving hole 525 improves the aesthetics of the bearing. The annular end cover 5 composed of two semicircular annular plates 524 is conducive to the staff to install, disassemble and overhaul the components on the annular end cover 5 in the later stage. The provision of the second bolt 5241 facilitates the staff to install and disassemble the two semicircular annular plates 524 in the later stage.

[0031] The control valve assembly 6 is arranged on the cover plate 52 and is used to open and close the oil outlet 511. The control valve assembly 6 includes a cylinder 61 and an extrusion plate 62. The cylinder 61 is fixed on the top of the cover plate 52. A signal receiver 611 electrically connected to the vehicle system is fixed on the cylinder body of the cylinder 61. A controller 612 electrically connected to the signal receiver 611 is fixed on the cylinder body of the cylinder 61. When refueling is required between the outer ring 1 and the inner ring 2, the staff needs to first send a signal to the signal receiver 611 through the vehicle system.

[0034] A rotating shaft seal 7 is provided between the inner wall of the annular end cover 5 and the side wall of the rotating shaft 4 to maintain the sealing between the annular end cover 5 and the rotating shaft 4. The rotating shaft seal 7 is a conventional means of transmission sealing between the shaft and the hole. The provision of the rotating shaft seal 7 increases the sealing between the annular end cover 5 and the rotating shaft 4.

[0035] The use principle of a new self-aligning clutch release bearing in this embodiment is as follows: the annular end cover 5 plays a good role in blocking dust and other debris during the use of the clutch release bearing, reducing the probability that dust, debris and other debris enter between the outer ring 1 and the inner ring 2 and affect the normal rotation of the ball 3. After the clutch release bearing has been used for a period of time, when the lubricating fluid in the bearing is reduced due to wear and consumption, the staff needs to start the cylinder 61. After the cylinder 61 is started, the piston rod of the cylinder 61 will drive the extrusion plate 62 at the end of the piston rod of the cylinder 61 to shrink in the direction away from the oil outlet hole 511, and the oil outlet hole 511 leaks out, so that the lubricating oil in the oil storage tank 51 can fall through the oil outlet hole 511 to the position between the outer ring 1 and the inner ring 2, thereby completing the refueling action, reducing the probability that the bearing is affected by wear and tear, resulting in a lack of lubricating fluid in the bearing and affecting the service life. In addition, the oil storage tank 51 can store a certain amount of lubricating fluid. After completing the refueling of the ball 3, the staff can use the control valve assembly 6 to close the oil outlet hole 511 in the oil storage tank 51 for the next refueling action.
