Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a quick-release aluminum alloy end cap for gearbox maintenance. Background Technology

[0002] The gearbox is a gearbox that changes the transmission ratio and direction of motion. It is located between the clutch and the central drive. Its main functions are: to change the driving force and speed of the vehicle while keeping the engine speed and torque constant; to enable the vehicle to move backward; and to allow the engine to stop without shutting off. The gearbox end cover is a key sealing component of the gearbox housing, mainly used to protect the internal parts of the gearbox.

[0003] In existing technology, such as Chinese Patent No. CN216242203U, a cover body is included. The top of the cover body has a snap-fit ​​mechanism, and the bottom of the snap-fit ​​mechanism has a connecting rod. A fixing mechanism is located in the middle of the cover body, and a rotating shaft is fixedly connected to the right side of the fixing mechanism. This gearbox sealing end cover, through the snap-fit ​​mechanism, allows the handle to drive the threaded rod to move horizontally to the left under the action of the threaded cylinder. When the right side of the threaded rod disengages from the first groove, it drives the trapezoidal locking block to move vertically downwards and enter the trapezoidal groove. This facilitates the installation and disassembly of the cover body and connecting rod. When a fault occurs inside the gearbox, disassembly is convenient during maintenance, improving the efficiency of maintenance personnel to a certain extent. The fixing mechanism secures the bearing to the cover body, preventing shaft misalignment and ensuring normal shaft operation. While the above solution has the advantages mentioned above, its disadvantages are that when installing the end cover, it is necessary to first turn the bolts and then turn the nuts and handles separately, which is cumbersome. Furthermore, since the end cover is installed by bolts, the bolts need to be turned separately to remove the end cover, which is very inconvenient when inspecting the gearbox. Utility Model Content

The push block 304 pushes the connecting plate 5 to move through the inclined surface on the left side of the connecting plate 5. 4. Push the two sets of connecting plates 5 to move. The connecting plates 5 drive the connecting slide plate 502 to move. The connecting slide plate 502 squeezes the connecting spring 5021. The inclined surface on the right side of the connecting plate 5 pushes the control plate 504 to move upward through the triangular groove 505. The control plate 504 pushes the insert plate 4 to move through the trapezoidal groove 506. While moving the left side of the insert plate 4 out of the inner cavity of the slot 101, it squeezes the fixing spring 402. After the two sets of insert plates 4 are moved out of the inner cavities of the two sets of slots 101 respectively, pull the end cover 2 upward to separate the end cover 2 from the gearbox 1. Release the push plate 303, and the push block 304 returns to its original position under the action of the support spring 3052. The connecting plate 5 returns to its original position under the action of the connecting spring 5021. The insert plate 4 returns to its original position under the action of the fixing spring 402. Pull the top plate 3, and the top plate 3 drives the installation slide plate 307 to move and limit and fix the right support plate 305. Insert the triangular plate 3011 into the inner cavity of the locking groove 301 to block the push plate 303, thus completing the disassembly of the end cover 2.
