Description

Technical Field

[0001] This utility model relates to the field of tracked vehicle maintenance tools, and in particular to a pneumatic quick-release tool for a clutch piston. Background Technology

[0002] During armored vehicle repair, the disassembly of the hydraulic shift clutch piston has always lacked specialized tools. The hydraulic shift clutch uses the movement of an internal piston to press and release the active and passive friction plates, thereby transmitting and cutting off power. To ensure the hydraulic oil is sealed, an O-ring is installed between the piston and the clutch inner hub. Under normal conditions, the piston is inside the mounting hole, and the combined effect of the oil film seal and atmospheric pressure makes piston disassembly difficult. Currently, the common disassembly method is an impact method: holding the hydraulic shift clutch face down with both hands and quickly impacting it against a sleeper, relying on the impact force to force the piston out. While this method can remove the clutch, it poses risks of personal injury and component damage, is time-consuming and labor-intensive, and carries certain safety hazards. Improvement is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide a pneumatic quick-release fixture for clutch pistons, solving the problems of difficulty in disassembling hydraulic shift clutch pistons and the risk of safety accidents and secondary damage to parts caused by repeated impacts using wooden blocks in existing technologies. This invention uses a hydraulic oil passage (control passage) to blow high-pressure gas into the hydraulic cylinder, effectively using high-pressure air as hydraulic oil to push the piston out, thus achieving quick disassembly.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: The pneumatic quick-release fixture for the clutch piston adopts a circular design and includes a main body 1 and a fixed part 2. The fixed part 2 is fixed to the base plate 5 of the main body 1 by nuts 8, and the outer side of the fixed part 2 is fixedly connected to the hydraulic shift clutch by screws 7. The high-pressure air quick connector 3 is installed on the air collection chamber 4 and the two are connected as one. The air collection chamber 4 is fixed to the main body 1. There are four positioning pins 6 on the base plate 5 of the main body 1. The positioning pins 6 are hollow and serve as air outlets for the air collection chamber 4. The four positioning pins 6 respectively cooperate with the four oil holes on the control oil passage 9 of the hydraulic shift clutch, thereby realizing the purpose of high-pressure gas entering the hydraulic shift clutch and pushing the piston to move.

[0005] The diameter of the high-pressure quick-connector 3 is 11mm.

[0006] The diameter of the air outlet is 8.4 mm.

[0007] The advantages of this invention are: simple structure, ingenious design, and safe and convenient use. By controlling the oil passage to blow high-pressure gas into the hydraulic cylinder, the high-pressure air acts as hydraulic oil to push the piston out, thus achieving rapid disassembly. This avoids the safety accidents and secondary damage to parts that can easily occur with repeated impacts using wooden blocks in traditional disassembly and assembly methods. It is highly practical.

[0012] See Figures 1 to 6 As shown, the pneumatic quick disassembly tool for the clutch piston of this utility model can align the control oil passage hole of the hydraulic shift clutch (which can realize the action of high pressure air on the piston), clamp the tool and connect the high pressure air, and push the piston to move by the pressure of the high pressure air, thereby realizing the quick disassembly of the piston and ensuring the smooth progress of repair work.

[0013] See Figures 1 to 4 As shown, the pneumatic quick-release tooling for the clutch piston of this utility model adopts an overall circular design and includes two parts: a main body 1 and a fixed part 2. The fixed part 2 is fixed to the base plate 5 of the main body 1 by nuts 8, and the outer side of the fixed part 2 is fixed to the hydraulic shift clutch by four tightened screws 7.

[0014] The upper end of the gas collecting chamber 4 fixed on the main body 1 is equipped with a high-pressure gas quick connector 3, a standard part, for easy and quick connection to a high-pressure source. The high-pressure gas quick connector 3 is connected to the gas collecting chamber 4, and the two are integrated. Four locating pins 6 are provided on the base plate 5 of the main body 1. The locating pins 6 are hollow and pass through the base plate 5, serving as the air outlets of the gas collecting chamber 4. The four locating pins 6 respectively cooperate with four oil holes on the control oil passage 9 of the hydraulic shift clutch, thereby enabling high-pressure gas to enter the hydraulic shift clutch and push the piston 10 to move. The diameter of the high-pressure gas quick connector 3 is 11 mm. The diameter of the air outlet is 8.4 mm.

High-pressure air enters the piston oil chamber through the air inlet channel 11. Under the action of air pressure, piston 10 is pushed out, avoiding the problem of multiple impacts and secondary damage to parts caused by the use of wooden blocks in traditional disassembly and assembly.
