Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically, to an automobile release fork connection structure. Background Art

[0002] The clutch release mechanism controls the separation and engagement of the clutch to achieve normal driving of the vehicle and smooth gear selection and shifting operations. The clutch release fork connects the clutch working cylinder and the release bearing in the clutch release mechanism, and uses the principle of leverage to reduce the operating force and improve the comfort of clutch operation.

[0003] Among them, the technology disclosed in the patent application No. CN201220499571.0 for a clutch release fork is also a technology that is becoming increasingly mature. The release fork has a larger leverage ratio, better self-strength, simplifies the clutch release mechanism connected thereto, does not require regular greasing during use for maintenance, has a longer service life, reduces the failure points during use, and also improves the appearance quality and has a more reasonable structure.

[0004] Based on this, while agreeing with the advantages of the above products, there are still the following defects:

[0005] This type of release fork reduces fork wear by setting rollers, but these rollers can only rotate around their axes. Therefore, they are prone to wear after long-term use, have a short service life, and are not easy to install, thus bringing a burden to the staff and reducing the practicality. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an automobile release fork connection structure to solve the problems of inconvenience in manual feeding and easy raw material waste proposed in the above background art.

[0007] An embodiment of the utility model provides an automobile release fork connection structure, including a claw. A fork body is arranged at the bottom end of the claw. A rotating assembly is arranged near the bottom end of the fork body. Mounting assemblies are arranged on both sides of the claw.

[0008] Among them, the rotating assembly includes a support column arranged at the bottom end of the fork body. A shifting sleeve is inserted inside the support column. A rubber ring is arranged at the bottom end inside the shifting sleeve. A fork support column is inserted and connected at the top of the rubber ring inside the shifting sleeve. A lubrication cavity is opened at the top end of the support column. A cover plate is arranged at the top of the support column at the lubrication cavity. A plurality of filling holes are annularly opened at the top end of the cover plate. A plurality of lubrication holes are annularly opened on the inner side wall of the support column near the top end. The filling holes, the lubrication cavity and the lubrication holes are communicated with each other.

[0009] In this embodiment, since the filling hole, the lubrication cavity and the lubrication hole are communicated, it is convenient for the staff to inject lubricating oil into the lubrication cavity of the support column. The lubricating oil then passes through the lubrication hole and finally disperses and flows into the inner side wall of the support column, making the toggle sleeve inside the support column rotate more sensitively and with less wear, and also facilitating the lubrication of the separation fork.

[0010] In an implementation scheme of the present utility model, threaded cylinders are arranged in the middle of the claw fingers of the installation assembly. Threaded rods are threadedly connected inside the threaded cylinders. A rotating disk is arranged outside the threaded rods. Clamping disks are arranged at the opposite ends of the threaded rods. A limiting disk is arranged in the middle of the threaded rods.

[0011] In this scheme, by rotating the rotating disk, the rotating disk drives the threaded rod and the clamping disk to rotate synchronously, so as to adjust the size between the clamping disks according to needs, making the connection and installation more convenient.

[0012] In an implementation scheme of the present utility model, springs are arranged at both sides of the inner side wall of the claw finger relative to the threaded cylinder. One end of the spring away from the claw finger is connected to a U-shaped plate. A threaded hole matching the threaded rod is opened in the middle of the U-shaped plate.

[0013] In this scheme, the threaded rod is kept stable during rotation through the spring, the U-shaped plate and the threaded hole.

[0014] In an implementation scheme of the present utility model, a connecting plate is arranged between the claw finger and the fork body. The limiting disk is located outside the U-shaped plate.

[0015] In this scheme, the connection between the claw finger and the fork body is made tighter through the connecting plate. The limiting disk is located outside the U-shaped plate, and the limiting disk pushes the U-shaped plate to move.

[0016] In an implementation scheme of the present utility model, a fixing block is arranged on the outer surface of the fork body. A hinge groove is opened on the inner side of the fixing block.

[0017] In this scheme, since a hinge groove is opened on the inner side of the fixing block, it is convenient for the staff to hinge and fix the fork body, and it can be conveniently buckled with the vehicle body and the hinge groove during use.

[0018] In an implementation scheme of the present utility model, the width of the U-shaped plate is greater than that of the claw finger, the diameter of the clamping disk is greater than that of the limiting disk, and the diameter of the threaded cylinder is greater than the width of the fork body.

[0019] In this scheme, since the width of the U-shaped plate is greater than that of the claw finger, it can ensure that the claw finger has a larger support surface during work. The diameter of the clamping disk is greater than that of the limiting disk, which can ensure that the clamping disk has a larger contact area during contact, thereby improving the clamping effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] When the staff installs the separation fork connection structure, by rotating the rotating disk, the rotating disk drives the threaded rod and the clamping disk to rotate synchronously. At the same time, the limit plate in the middle of the threaded rod 1 pushes the movement of the U-shaped plate. The spring, U-shaped plate and threaded hole ensure that the threaded rod maintains stability during rotation to prevent loosening or deviation during rotation. The size between the clamping plates can be adjusted according to needs to make the connection and installation more convenient. Since the inner side of the fixing block is provided with a hinge groove, it is convenient for the staff to hinge and fix the fork body. When in use, it can be conveniently buckled with the vehicle body and the hinge groove to ensure the stability of the fork body during use.

[0022] When the staff adds lubricating oil to the separation fork connection structure, since a filling hole is provided at the top of the cover plate, the filling hole is connected to the lubrication cavity and the lubrication hole, which makes it convenient for the staff to inject the lubricating oil into the lubrication cavity of the support column. The lubricating oil finally disperses and flows into the inner side wall of the support column through the lubrication hole, making the rotation of the shift sleeve inside the support column more sensitive and less worn, and also making it convenient to add lubricating oil to the separation fork.
