Description

Technical Field

[0001] This utility model relates to the field of automotive clutch release bearing shift fork technology, specifically an automotive clutch release bearing shift fork structure. Background Technology

[0002] As a key component of the clutch system, the clutch bearing shift fork plays a decisive role in the normal operation of the clutch. Its working principle is that when the clutch pedal is depressed, the power booster pump outputs force to push the push rod, which acts on the ball socket at one end of the shift fork. With the bearing housing as the fulcrum, the shift fork rotates, which in turn pushes the release bearing to press against the clutch pressure plate, thereby disengaging the clutch and cutting off the power transmission between the engine and the transmission. During frequent gear shifting and starting operations, the clutch bearing shift fork is always in a high-intensity working state.

[0003] From a structural design perspective, the shift fork is subjected to complex stress over a long period of time, making it prone to wear at key locations such as the contact area between the fork foot and the release bearing, as well as the pivot point of the shift fork. As the usage time increases, the wear intensifies, and under the action of external forces, it can cause structural deformation of the bearing fork body or even cracking and breakage. When the shift fork shows wear and cracking, it is difficult to detect metal damage. Because the installation location of the shift fork is usually relatively hidden and the surrounding space is narrow, it is difficult to use conventional testing methods for comprehensive and accurate testing. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for a release bearing fork in an automotive clutch, which has the advantages of convenient inspection and maintenance, high installation accuracy, and stable structure. It solves the problem that the existing automotive clutch bearing fork is prone to wear and cracking under long-term use, and its metal damage is not easy to detect, making installation and disassembly inconvenient, resulting in difficult maintenance and time-consuming and labor-intensive repairs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A clutch release bearing shift fork structure for automobiles includes a shift fork assembly, a reinforcement and maintenance assembly, and a positioning rod sleeve assembly. The reinforcement and maintenance assembly is located on the inner side of the shift fork assembly. The positioning rod sleeve assembly is located at the upper end of the shift fork assembly. The shift fork assembly includes a bearing fork and fork feet. Fork feet are located on both sides of the lower end of the bearing fork, and the fork feet are integrally formed with the bearing fork. Ribs are located on the inner side of the bearing fork, and the ribs are integrally formed with the bearing fork. Reinforcing ribs are located at the lower end of the ribs, and the reinforcing ribs are integrally formed with the ribs, and both ends of the reinforcing ribs are integrally formed with the bearing fork. A clutch push rod sleeve is located at the upper end of the bearing fork, and the clutch push rod sleeve is integrally formed with the bearing fork. Fluid injection glass rings are located on both sides of the ribs and reinforcing ribs, and both ends of the fluid injection glass rings are fixedly connected to the ribs and reinforcing ribs, respectively.

[0007] Preferably, the upper end of the clutch push rod sleeve is provided with a mounting protrusion, and the mounting protrusion is integrally formed with the clutch push rod sleeve.

[0008] It is worth noting that the protruding structure of the mounting plate facilitates the installation and rotation adjustment of the clutch push rod sleeve.

[0009] Preferably, a scale calibration plate is provided in front of the clutch push rod sleeve, and the scale calibration plate is integrally formed with the mounting protrusion.

[0010] It is worth noting that the clutch push rod sleeve is fixed to the clutch push rod inserted into its hole by screws. Since the mounting cam and the angle adjustment lug are perpendicular to each other, when the clutch push rod sleeve and the clutch push rod are misaligned during assembly, the scale calibration plate can intuitively show the relative misalignment between the clutch push rod sleeve and the clutch push rod, thus improving the overall assembly accuracy of the device.

[0011] Preferably, both ends of the inner wall of the clutch push rod sleeve are provided with screw holes, and the screw holes are integrally formed with the clutch push rod sleeve.

[0012] It is worth noting that the screw hole is used for the screw to pass through the clutch push rod sleeve and be fixedly connected to the clutch push rod.

[0013] Preferably, the inner wall of the hole in the clutch push rod sleeve is provided with a rubber anti-slip layer.

[0014] It is worth noting that the rubber anti-slip layer improves the connection stability when assembling the clutch push rod sleeve and the clutch push rod, and reduces structural gaps.

[0015] Preferably, the liquid-filled glass ring is a hollow glass structure, and the hollow glass of the liquid-filled glass ring is filled with iron oxide red pigment solution.

[0016] It is worth noting that when the ribs and reinforcing ribs are damaged and crack or deform, the injection glass ring will break, causing the iron oxide red pigment solution inside the injection glass ring to leak from the broken glass. When maintenance personnel inspect the bearing fork, if the pigment inside the injection glass ring is lost, this phenomenon can be used to determine that the ribs, reinforcing ribs, and bearing fork structure have undergone structural deformation or cracking, thereby quickly assisting maintenance personnel in replacing the structure and greatly improving the convenience of device maintenance.

[0017] Preferably, one side of the clutch push rod sleeve is provided with an angle adjustment ear, and the angle adjustment ear is integrally formed with the clutch push rod sleeve, and the mounting protrusion and the angle adjustment ear are set at a perpendicular angle to each other.

[0018] It is worth noting that the assembly posture of the clutch push rod sleeve can be precisely adjusted by inserting the external adjusting rod into the angle adjusting lug and rotating it, which reduces the assembly difficulty and improves the installation accuracy.

[0019] Preferably, a wear-resistant post is provided on the inner side of the fork leg, and the wear-resistant post is fixedly connected to the bearing fork.

[0020] It is worth noting that the wear-resistant column improves the wear resistance of the fork feet and extends the service life of the device.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention significantly enhances the stability of the inner structure of the bearing fork by incorporating ribs and reinforcing ribs, reducing the impact of external forces on the inner side of the bearing fork and preventing cracks. Furthermore, a liquid-filled glass ring is fixed to both sides of the ribs and reinforcing ribs. When the ribs or reinforcing ribs are damaged and crack or deform, the liquid-filled glass ring will break, causing the iron oxide red pigment solution inside the glass ring to leak out. When maintenance personnel inspect the bearing fork, if the pigment inside the liquid-filled glass ring leaks out, this phenomenon indicates structural deformation or cracking of the ribs, reinforcing ribs, and bearing fork structure. This allows for rapid replacement of the structure, greatly improving the ease of maintenance of the device.

[0023] By setting up the positioning rod sleeve assembly, the clutch push rod sleeve is fixed to the clutch push rod inserted into its hole by screws. Since the mounting cam and the angle adjustment lug are perpendicular to each other, when the clutch push rod sleeve and the clutch push rod are misaligned during assembly, the scale calibration plate can intuitively show the relative misalignment between the clutch push rod sleeve and the clutch push rod, improving the overall assembly accuracy of the device. The assembly posture of the clutch push rod sleeve can be precisely adjusted by inserting the external adjustment rod into the angle adjustment lug and rotating it, reducing the assembly difficulty and improving the installation accuracy.

[0034] The upper end of the clutch push rod sleeve 301 is provided with a mounting protrusion 302, and the mounting protrusion 302 is integrally formed with the clutch push rod sleeve 301.

[0035] A scale calibration plate 303 is provided in front of the clutch push rod sleeve 301, and the scale calibration plate 303 is integrally formed with the mounting protrusion 302.

[0036] Both ends of the inner wall of the clutch push rod sleeve 301 are provided with screw holes 305, and the screw holes 305 are integrally formed with the clutch push rod sleeve 301.

[0037] The inner wall of the hole in the clutch push rod sleeve 301 is provided with a rubber anti-slip layer 306.

[0038] The liquid-filled glass ring 203 is a hollow glass structure, and the hollow glass of the liquid-filled glass ring 203 is filled with iron oxide red pigment solution.
