Description

Technical Field

[0001] The utility model relates to the field of vehicle maintenance equipment, in particular to a clutch bearing clamp ring disassembly and assembly tool. Background Art

[0002] Trailer gearbox maintenance is an extremely tedious process. Each step requires precise alignment and close coordination. Among them, the installation of the clutch release bearing retaining ring has always been one of the difficulties.

[0003] The clutch release bearing retaining ring is different from the general leaf retaining spring. The whole structure is a ring-shaped metal rod with an interrupted notch. At the two ends of the ring-shaped metal rod, i.e. the interrupted position, two straight rods are bent toward the outside of the ring as the operating part. When installing, pinch the two straight rods to shrink the ring, put it into the installation position and release it. The metal rod will expand naturally due to its own elasticity and then be stuck into the installation position.

[0004] When installing the gearbox, the gearbox must be docked before the clutch release bearing retaining ring can be installed and locked. However, at this time, the installation can only be completed through a 10cm*5cm shift fork hole at the bottom of the vehicle. The operating space is extremely narrow and ordinary tools cannot be used. Therefore, it is usually completed through the cooperation of two people. One person holds the shift fork, and the other person reaches into the shift fork hole with bare hands to install the retaining ring. There are many parts inside the gearbox. If you are not careful, your fingers will be squeezed and injured, which poses a great safety hazard. Summary of the invention

[0005] The utility model provides a clutch bearing snap ring disassembly and assembly tool to solve the problems that the current manual installation of a clutch bearing snap ring is inconvenient and has potential safety hazards.

This solution designs a clamp-type bearing retaining ring disassembly and assembly tool, which can be extended into the gearbox through the fork hole to reach the bearing end face, and the transversely extending cross bar is provided with a notch that can be matched to match the bending sections at both ends of the bearing retaining ring, which is not easy to loosen. This tool is easy to use and can disassemble and assemble the bearing retaining ring more safely and quickly.

[0007] Preferably, the first body and the second body are both rod-shaped, and both include a straight rod section and an arc section. The straight rod section and the arc section of the first body and the second body are rotatably connected at the hinge, and the cross bar is located at the end of the straight rod section. The front part of the tool body is a straight rod, so that the part extending into the gearbox is a slender structure, which is more flexible in the narrow inner cavity of the gearbox, and the rear part is arc-shaped to improve the grip and operation feel.

[0008] Preferably, the cross bar is perpendicular to the straight bar section.

[0009] Preferably, the cross section of the notch is a right-angled trapezoid, the right-angled side of the right-angled trapezoid is close to the end of the crossbar away from the first body or the second body; the long bottom side of the right-angled trapezoid is located on the side where the two notches are close to each other. The hypotenuse of the right-angled trapezoid pushes the bent section of the bearing retaining ring forward, making it easier to clamp and install in place.

[0010] Preferably, a long hole is provided in the middle of one of the first body and the second body, and an insertion rod is provided on the other of the first body and the second body, and the insertion rod is inserted into the long hole and can move in the long hole. The long hole structure can adjust the rotation center between the first body and the second body and adjust the distance between the front ends of the two.

[0011] Preferably, the length of the straight rod section is 15 cm.

[0012] Preferably, the first body and the crossbar thereon are an integral bending structure; the second body and the crossbar thereon are an integral bending structure. The integral manufacturing is convenient for use and has high strength.

[0013] Through the above technical scheme, it can be seen that the advantages of the utility model are that this scheme designs a clutch bearing retaining ring disassembly and assembly tool for the characteristics of the small opening of the gearbox fork hole and the many interferences of the internal structure. The tool is a clamp structure as a whole, and the front part is slender, which can be easily and flexibly extended into the gearbox. The front end is provided with a cross bar and an upper notch that can reach the bearing section to clamp the bent sections at both ends of the bearing retaining ring. The notch section is a right-angled trapezoid with a large opening, which can easily engage the position of the bent section. The hypotenuse of the trapezoidal section pushes the bent section forward, so that it is not easy to shake out after being clamped and is closer to the installation position of the bearing end face. The overall structural design of the tool is ingenious and the use is flexible and convenient, which greatly improves the efficiency of gearbox maintenance and the safety of clutch bearing retaining ring disassembly and assembly operations.
