Description

Technical Field

[0001] The utility model relates to the technical field of shift fork shafts, in particular to a shift fork shaft which is easy to assemble and disassemble. Background Art

[0002] With the technological development of the automotive industry and people's pursuit of new energy, technology and intelligence, we are prompted to fully consider the applicability, technology, intelligence and product integration of the products during the research and development process. The shift fork shaft is installed in the shift fork mounting hole on the transmission housing. The shift fork mounting hole supports and limits the shift fork shaft so that the shift fork shaft can move axially to achieve gear shifting.

[0003] According to the search, Chinese patent literature, announcement number: CN221278434U, discloses a multifunctional shift fork shaft structure. After the shift fork shaft and shift block are assembled, the positioning spring cotter pin is installed and tightened to complete the assembly of the component, and then it is installed in the automobile transmission to form a shift assembly. When the shift lever is operated to shift the shift fork shaft, the shift fork shaft shifts the gear position and drives the shift block, and the shift block side fork surface at the bottom of the shift block is used to realize the first and second gear shifting of the automobile transmission, and the neutral gear shifting and locking. At the same time, the shift fork shaft gear position display starts to work during the movement. When the gear display switch moves to the left, it displays first gear; conversely, when it moves to the right, it displays second gear; when the shift fork shaft moves the shift fork shaft to the neutral lock position, the lock switch displays neutral. This product has a novel structure, is simple and convenient to operate, is reliable, energy-saving and cost-reducing, and meets multi-purpose use. However, in the process of completing the assembly of the components by installing the positioning spring cotter pin to tighten it, the overall structure is more troublesome to disassemble at the later stage, which requires a lot of time. In addition, after installation, it is tightened and fixed by the elasticity of the positioning spring, resulting in poor overall stability after installation and a short service life.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figure 1-5 As shown, the utility model provides a fork shaft that is easy to disassemble and assemble, including a fork shaft body 1, a positioning hole 2 is opened on the outside of the fork shaft body 1, a cavity 3 is opened on the inside of the fork shaft body 1, a mounting plate 4 is provided on the inside of the cavity 3, a fastening block 5 is fixedly installed on the outside of the mounting plate 4, a reinforcing rod 6 is installed on the inside of the mounting plate 4 by snap-fitting, a fixing sleeve 7 is threadedly connected to the left side of the fork shaft body 1, and a fork body 8 is installed on the outside of the positioning hole 2 by snap-fitting.

[0033] Specifically, a through slot 201 is formed on the top side of the inner side of the positioning hole 2. The through slots 201 are arranged in groups of two, for a total of three groups. Furthermore, there are three positioning holes 2, which are equidistantly arranged on the outer side of the shift fork shaft body 1. Advantageously, the positioning holes 2 facilitate positioning and installation of the shift fork body 8, and the through slots 201 help limit the position of the fastening block 5, improving installation stability.

[0034] Specifically, a fitting groove 301 is defined on the right side of cavity 3, the size and shape of which match those of reinforcement rod 6. A connecting sleeve 302 is fixedly mounted on the left side of fork shaft body 1, with threads formed on the outer side of connecting sleeve 302. Advantageously, fitting groove 301 restrains the right end of reinforcement rod 6, preventing it from loosening. Furthermore, connecting sleeve 302 facilitates installation of fixing sleeve 7.

[0035] Specifically, two mounting plates 4 are provided, with a cylinder 401 and an inner rod 402 fixedly mounted between them. The inner rod 402 is movably mounted on the inner side of the cylinder 401. A spring is fixedly mounted between the cylinder 401 and the inner rod 402. A limiting slot 403 is provided on the inner side of the mounting plate 4. Advantageously, the insertion of the reinforcement rod 6 improves the stability of the mounting plate 4 during movement under the action of multiple sets of cylinders 401 and inner rods 402. Furthermore, when the reinforcement rod 6 is removed, the spring disengages the fastening block 5 from the retaining slot 801, thereby facilitating the removal of the fork body 8.

[0036] Example 2:

[0037] like Figure 1-5 As shown, as an improvement to the previous embodiment, a limit plate 601 is fixedly mounted on the outer side of the reinforcement rod 6. The size and shape of the limit plate 601 match the size and shape of the limit slot 403. A threaded hole 602 is provided on the left side of the reinforcement rod 6. Advantageously, the engagement of the limit plate 601 with the limit slot 403 improves the overall stability after installation, and the threaded hole 602 facilitates the connection of the reinforcement bolt 702.

[0038] Specifically, the fixing sleeve 7 has threads formed on its inner side, and a connecting hole 701 is formed on its left side.

[0039] Specifically, a slot 801 is defined on the top inner side of the fork body 8. The size and shape of the slot 801 match the fastening block 5. The slots 801 are arranged in groups of two, one on the top and one on the bottom inner side of the fork body 8. This advantageously allows the fastening block 5 to tightly engage with the slot 801, facilitating the installation and securing of the fork body 8 and the fork shaft body 1. Furthermore, the slot 801 positions the fastening block 5, improving stability during subsequent use and preventing it from falling off.

[0040] When in use, the three groups of fork bodies 8 are respectively sleeved and installed with the fork shaft body 1. During the sleeve installation process, the reinforcement rod 6 is inserted into the two mounting plates 4 and engaged with the fitting groove 301. The action of the fitting groove 301 is conducive to improving the stability of the reinforcement rod 6. When the reinforcement rod 6 is inserted, it is engaged with the limiting groove 403 under the action of the limiting plate 601, thereby pushing the fastening block 5 to move relatively and engage tightly with the slot 801, thereby maximizing the connection stability during use, which is conducive to use. During the process, the connection stability is improved, and then the fixing sleeve 7 is connected to the connecting sleeve 302 through a thread, and the reinforcing bolt 702 is passed through the connecting hole 701 and connected to the threaded hole 602, which is conducive to reinforcing the left end of the reinforcing rod 6. During disassembly, after removing the reinforcing bolt 702, the fixing sleeve 7 is rotated to facilitate the removal of the reinforcing rod 6. Then, under the action of the spring, the fastening block 5 is disengaged from the slot 801, thereby facilitating the removal of the fork body 8. The disassembly and assembly are convenient and quick, and the overall installation structure is highly stable.
