Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a gear selection inner lining sleeve. Background Art

[0002] Bushings play a crucial role in mechanical components, particularly the gear selector mechanism in automotive transmission systems. They are typically designed to reduce friction, provide wear protection, ensure a tight fit between components, and enhance overall system durability and performance. Traditional gear selector mechanisms, without bushings, have direct metal-to-metal contact, leading to rapid wear and potential failure.

[0003] With the development of the automotive industry, consumers' demands for a superior driving experience and vehicle durability are increasing. Therefore, designing a new gear selector bushing is becoming increasingly important. This bushing must possess excellent wear and corrosion resistance, as well as appropriate elasticity to ensure stable performance over long-term use.

[0004] Existing gear selector inner sleeves may be made of a variety of materials, such as rubber, plastic or special synthetic materials. The selection of these materials depends on their application environment, expected load and required performance characteristics; however, the current gear selector inner sleeve has poor adaptability and is inconvenient to match the tightening mouth on the dust cover and the gear lever, which makes it inconvenient to install; for this reason, the present application proposes a gear selector inner sleeve. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a gear selection inner sleeve.

[0006] The embodiment of the present utility model provides a gear selection inner sleeve, comprising:

[0007] A sleeve, wherein three bolt holes are formed through the sleeve and a protrusion is fixed on the sleeve;

[0008] Limiting assembly; the limiting assembly includes a connecting pipe fixed at the bottom of the sleeve, and a plurality of limiting rings are fixed on the outer wall of the connecting pipe, and an annular limiting groove is formed between two adjacent limiting rings and between the limiting ring and the sleeve.

[0009] Furthermore, the sleeve, the connecting pipe and the limiting ring are integrally formed, and the sleeve, the connecting pipe and the limiting ring are all made of rubber or plastic.

[0010] Furthermore, the inner diameter of the connecting pipe is the same as the inner diameter of the sleeve, and the outer diameter of the connecting pipe is smaller than the outer diameter of the sleeve.

[0011] Furthermore, the three bolt holes are evenly distributed on the sleeve at an angle of 270°.

[0012] Furthermore, the protrusion and the three bolt holes are located on the same circumference and are distributed in a ring array.

[0013] Furthermore, the connection between the protrusion and the sleeve is arranged in an arc shape.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model is provided with three bolt holes, which increases the adaptability of the sleeve. The sleeve can be fixed on the gear lever by installing bolts on the bolt holes and connecting them with the screw holes on the gear lever. The sealing sleeve can also be connected to the connecting pipe by selecting a suitable limiting groove according to the length of the sealing sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the present utility model provides a gear selection inner sleeve, comprising:

[0022] The sleeve 1 is provided with three bolt holes 3, which are evenly distributed on the sleeve 1 at 270°, increasing the adaptability of the sleeve 1. The sleeve 1 can be fixed on the gear lever by installing bolts on the bolt holes 3 and connecting them with the screw holes on the gear lever; a protrusion 2 is fixed on the sleeve 1, and the protrusion 2 and the three bolt holes 3 are located on the same circumference and are distributed in a circular array. The connection between the protrusion 2 and the sleeve 1 is arranged in an arc shape, so that the protrusion 2 can be connected to the gear sleeve arranged on the outside.

[0023] Limiting assembly; the limiting assembly includes a connecting tube 4 fixed at the bottom of the sleeve 1, and a plurality of limiting rings 5 ​​are fixed to the outer wall of the connecting tube 4. The sleeve 1, the connecting tube 4 and the limiting ring 5 are integrally formed, and the sleeve 1, the connecting tube 4 and the limiting ring 5 are all made of rubber or plastic. The inner diameter of the connecting tube 4 is the same as the inner diameter of the sleeve 1, and the outer diameter of the connecting tube 4 is smaller than the outer diameter of the sleeve 1, so it is convenient to install on the gear lever and is not easy to shake.

[0024] An annular limiting groove 6 is formed between two adjacent limiting rings 5 ​​and between the limiting ring 5 and the sleeve 1. After the utility model is installed on the gear lever, the sealing sleeve on the gear position can be sleeved in the annular limiting groove 6 on the connecting pipe 4. Since there are multiple annular limiting grooves 6, a suitable annular limiting groove 6 can be selected according to the length of the sealing sleeve, so that the sealing sleeve can be connected to the connecting pipe 4.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
