Description

Technical Field

[0001] The utility model relates to the field of clutch release bearings, in particular to a quick-disassembly and assembly clutch release bearing. Background Art

[0002] The clutch release bearing is an important component of the clutch release system. It is installed in the gearbox, located between the clutch and the transmission. The release fork is driven to move the release bearing back and forth along the axial direction of the gearbox guide tube to achieve the separation and combination of the clutch. In the Chinese utility model patent with the announcement number CN219865978U, a clutch release bearing that is easy to disassemble is disclosed. By setting an elastic snap member, the second elastic member is supported by deformation support, which can support the snap plate combination or release the snap connection with the outer jacket, so as to achieve the advantage of simply releasing the snap plate and improving the convenience of disassembly of the clutch release bearing. The deformation ability of the second elastic member has a certain service life. After long-term use, its elastic force will be reduced, which will lead to the risk of it being loose. At present, when installing the clutch release bearing, the clutch release bearing is generally aligned with a bearing first, and then installed in the gearbox by bolts. In this way, both the ordinary bearing and the clutch release bearing need to be disassembled during disassembly, and the operation is relatively complicated. For this reason, we designed a clutch release bearing that can be quickly disassembled. Utility Model Content

[0006] As a further improvement of the above scheme, a connecting screw hole is opened on the upper end surface of the protrusion, and the connecting screw hole extends downward to the connecting ring. The connecting block and the protrusion are fixed by countersunk bolts and connecting screw holes, so that the connecting ring can be quickly fixed on the mounting ring.

The upper surface of the connecting block is provided with an embedding groove 2, and a friction part 2 is arranged in the embedding groove 2. The friction part 1 is in contact with the friction part 2, which increases the resistance between the fixed block and the connecting block and makes the connection between the two more secure.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0025] A countersunk screw hole is provided on the upper end surface of the protrusion 12, and the countersunk screw hole extends downward through the fixing block 11, and a countersunk bolt 2 is arranged in the countersunk screw hole, which can quickly fix the mounting ring 1 in the gearbox.

[0026] A connecting screw hole 121 is provided on the upper end surface of the protrusion 12, and the connecting screw hole 121 extends downward to the connecting ring 3, and the connecting block 31 is fixed to the protrusion 12 by countersunk bolts 6 and the connecting screw hole 121, so that the connecting ring 3 can be quickly fixed to the mounting ring 1.

[0027] A moving hole 311 is provided on the surface of the connecting block 31, and the moving hole 311 is connected to the connecting screw hole 121. A positioning pin 7 is provided in the moving hole 311 for linear sliding back and forth. A pushing groove 71 is provided above the outer ring surface of the positioning pin 7. The bottom end of the countersunk bolt 6 is in sliding contact with the pushing groove 71. During the upward movement of the countersunk bolt 6, its bottom end can contact with the pushing groove 71 and push the positioning pin 7 to move outward, so that it can be inserted into the locking groove of the countersunk bolt 2, which can limit the rotation of the countersunk bolt 2, so that it can be ensured to be at a suitable torque without frequent disassembly and assembly, and it is not easy to loosen;

[0028] The head of the countersunk bolt 2 is designed to be lengthened, and a locking groove is provided on the outer ring surface thereof, and the positioning pin 7 is inserted into the locking groove.

[0029] The cross-section of the push groove 71 is designed to be an inclined surface, and a contact portion is provided at the bottom end of the countersunk bolt 26. The contact portion is a hemispherical structure, and the width of the push groove 71 is greater than the outer diameter of the countersunk bolt 26. The hemispherical contact portion is convenient for contacting the push groove 71 and can easily move it.

[0030] The inner wall of the card interface is designed with an arc-shaped structure, and the center of the arc-shaped structure is collinear with the center of the mounting ring 1. The outer ring surface of the connecting block 31 is designed with an arc-shaped structure, and the center of the outer ring of the connecting block 31 is collinear with the center of the mounting ring 1. The connecting block 31 can be perfectly connected to the card interface when rotating.

[0031] The upper surface of the fixing block 11 is recessed downward to form an embedding groove 1, in which a friction portion 111 is arranged. The upper surface of the connecting block 31 is provided with an embedding groove 2, in which a friction portion 2 is arranged. The friction portion 111 is in contact with the friction portion 2, thereby increasing the resistance between the fixing block 11 and the connecting block 31 and making the connection between the two more secure.

[0032] A sealing ring is arranged between the head of the countersunk bolt 2 and the countersunk screw hole, and a sealing ring is arranged between the head of the countersunk bolt 6 and the connecting screw hole 121, to ensure the sealing performance, so that grease and dust outside the countersunk bolt 6 and the screw section of the countersunk bolt 2 will not enter, and will not cause rust, etc., which is convenient for subsequent disassembly.

[0033] The implementation principle of a quick-disassembly clutch release bearing in the embodiment of the present application is as follows: during installation, the mounting ring 1 is first installed in the gearbox through the countersunk bolt 1 2, and then the connecting ring 3 is fitted on the mounting ring 1 and rotated so that the connecting block 31 is plugged into the card interface, and then multiple countersunk bolts 2 6 are screwed into the connecting screw holes 121 in sequence, and the contact portion at the bottom end of the countersunk bolt 2 6 will push the pushing groove 71 of the positioning pin 7 and move it outward, thereby enabling the positioning pin 7 to be plugged into the locking groove of the countersunk bolt 2, so that it can be limited and cannot be rotated. In the subsequent disassembly process, it is only necessary to disassemble the connecting ring 3 for replacement and installation, and the mounting ring does not need to be disassembled;

[0034] By designing the mounting ring 1 and the connecting ring 3 as split parts and connecting the two separately, the mounting ring 1 is always fixed in the gearbox. When disassembling, only the connecting ring 3 needs to be removed to remove the clutch release bearing, thereby reducing the number of bolts. In addition, the sealing ring provided in combination ensures that the screw sections of the countersunk bolt 2 6 and the countersunk bolt 1 2 will not align and cause rust, etc., thus facilitating subsequent disassembly.

[0035] A positioning pin 7 is slidably arranged in the connecting block 31 of the connecting ring 3. When the countersunk bolt 2 6 fixes the connecting ring 3, the positioning pin 7 can be inserted into the countersunk bolt 1 2, thereby limiting the position of the connecting ring 3 and ensuring that the connecting ring 3 is at a suitable torque without the need for frequent disassembly and assembly, and is not prone to loosening.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
