Description

Technical Field

[0001] This utility model relates to the field of bearing assembly technology, and in particular to an automotive clutch release bearing assembly with a flexible damping connection. Background Technology

[0002] The clutch release bearing is a key component of the automotive transmission system. It is installed between the clutch and the gearbox. By coordinating the rotation and axial movement of the release lever, it achieves smooth engagement and disengagement of the clutch, reduces wear, and extends the service life of the transmission system. Its structure is loosely fitted on the first shaft bearing cover of the gearbox, and relies on a return spring to maintain the gap with the end of the release lever to ensure operational stability.

[0003] The existing release bearing and clutch shift fork are mostly rigidly connected. During driving, impact forces are generated at the moment of clutch engagement and disengagement or due to uneven operation by the driver. The rigid connection causes the inner and outer rings, cage and balls of the bearing to directly bear these impacts, reducing the bearing life. At the same time, it also generates vibration and noise. Because of the rigid connection, the vibration and noise are directly transmitted to the clutch shift fork and even the cockpit, affecting the driving experience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automotive clutch release bearing assembly with a flexible damping connection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A car clutch release bearing assembly with flexible damping connection includes a clutch fork, a fixing block at the top of the clutch fork, a fixing sleeve between the clutch fork and the fixing block, a bearing body fixedly installed in the fixing sleeve, a fixing ring fixedly installed on the left side wall of the fixing sleeve, a buffer ring fixedly installed on the right side wall of the fixing sleeve, a buffer spring provided on the left side of the buffer ring, the buffer spring being movably sleeved on the outside of the fixing sleeve, and a limit sleeve fixedly installed on the right side of the clutch fork and the fixing block corresponding to the position of the buffer spring.

[0006] As a further embodiment of this utility model, a movable block is fixedly installed on the top of the fixed block, and a movable groove is provided on the clutch shift fork corresponding to the position of the movable block. The movable block can be movably inserted into the movable groove. A fixed groove is provided on the top of the clutch shift fork corresponding to the position of the movable groove, and a screw is movably installed in the fixed groove.

[0007] As a further embodiment of this utility model, the movable block is provided with a threaded groove. After the movable block is inserted into the movable groove, the threaded groove will be aligned with the fixed groove, and the screw can be threadedly installed in the threaded groove.

[0008] As a further embodiment of this utility model, a connecting rod is fixedly installed on the bottom side of the fixing block, and a connecting groove is provided on the clutch shift fork at the position corresponding to the connecting rod, so that the connecting rod can be inserted into the connecting groove.

[0009] As a further embodiment of this utility model, a rubber pad is provided between the right side of the fixing ring and the clutch shift fork and the fixing block, and the rubber pad is fitted onto the fixing sleeve.

[0010] As a further embodiment of this utility model, a limiting block is movably installed on the side wall of the clutch shift fork, and the limiting block is fixed on the vehicle body.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by fitting the clutch shift fork and the fixed block onto the outside of the fixed sleeve, then inserting the connecting rod into the connecting groove, inserting the movable block into the movable groove, and finally inserting the screw into the fixed groove, the clutch shift fork and the fixed block are fixedly connected together. The fixed sleeve is movably mounted on the clutch shift fork and the fixed block. When the bearing body and the clutch disc vibrate during driving, the bearing body can move to the left because a buffer spring is provided between the bearing body and the clutch shift fork. The buffer spring can buffer the impact force on the bearing body, improve the bearing life, and at the same time greatly reduce the vibration and noise transmitted to the clutch shift fork, thus improving the driving experience.

The bearing body 4 can move to the left. The buffer spring 6 can buffer the impact force on the bearing body 4, improve the bearing life, and at the same time greatly reduce the vibration and noise transmitted to the clutch fork 1, improving the driving experience.

[0018] In this embodiment, a movable block 11 is fixedly installed on the top of the fixed block 2. A movable groove 13 is provided on the clutch shift fork 1 at the position corresponding to the movable block 11. The movable block 11 can be movably inserted into the movable groove 13. A fixed groove 14 is provided on the top of the clutch shift fork 1 at the position corresponding to the movable groove 13. A screw 8 is movably installed in the fixed groove 14. A threaded groove 12 is provided on the movable block 11. After the movable block 11 is inserted into the movable groove 13, the threaded groove 12 will align with the fixed groove 14. The screw 8 can be threaded into the threaded groove 12. A connecting rod is fixedly installed on the bottom side of the fixed block 2. Connecting rod 9 and clutch shift fork 1 are provided with connecting groove 10 at the position corresponding to connecting rod 9. Connecting rod 9 can be inserted into connecting groove 10. By putting clutch shift fork 1 and fixing block 2 on the outside of fixing sleeve 3, the buffer spring 6 is placed on the right side of clutch shift fork 1 and fixing block 2. Then, connecting rod 9 is inserted into connecting groove 10, movable block 11 is inserted into movable groove 13, screw 8 is inserted into fixing groove 14, and then screw 8 is rotated so that the bottom of screw 8 is inserted into thread groove 12.

The right side of the bearing body 4 in the fixed sleeve 3 is connected to the clutch. When the clutch plates engage and disengage during driving or when vibration occurs due to uneven operation by the driver, the bearing body 4 can move to the left because a buffer spring 6 is provided between the bearing body 4 and the clutch shift fork 1. The buffer spring 6 can buffer the impact force on the bearing body 4, improve the bearing life, and at the same time greatly reduce the vibration and noise transmitted to the clutch shift fork 1, thus improving the driving experience. When the right end of the clutch shift fork 1 is pushed by the hydraulic cylinder to control the movement of the fixed sleeve 3, the rubber pad 16 provided between the fixed ring 15 and the clutch shift fork 1 and the fixed block 2 can further reduce the noise transmitted from the fixed sleeve 3 to the clutch shift fork 1 and the fixed block 2.
