Problems solved by technology

In the prior art, the support bolts of the release shift fork are made of metal materials. In this way, when the gearbox is working, the release shift fork and the support bolts are in metal-to-metal contact, which makes the noise loud, and the metal to metal cannot be reliably lubricated, resulting in The amount of wear is large, and the service life of the support bolt is short. If it is used for a period of time without replacement, it will affect the control accuracy of the gearbox, and this will increase the cost
The support bolts of metal materials in the prior art are heavy and cannot meet the overall requirements for lightweight vehicles

Embodiment 1

[0039] A transmission fork support bolt whose ball head is made of POE material, the material of the ball head 2 of the bolt is POE and glass fiber accounting for 18% of the POE mass, as shown in the attached Figure 1~3 shown.

[0040] The bolt ball head 2 is sleeved on one end of the bolt body 1, and the external connecting sleeve 3 is connected with the movable sleeve of the bolt ball head, and the external connecting sleeve 3 is connected with the separating shift fork body of the gearbox.

[0041]With the above-mentioned structure, when designing or manufacturing the supporting bolts for the gearbox release shift fork (support pins for the gearbox release shift fork), after the bolt body 1 is processed and shaped, the bolt body 1 is then put into the mold and POE is directly injected onto the bolt body 1 A bolt ball head 2 is formed on the top, the bolt body is made of metal material, and the bolt ball head is made of plastic material. In this way, when the transmission ...

Embodiment 2

[0061] A gearbox separation shift fork support bolt whose ball head is made of POE material. The raw materials of the ball head 2 of the bolt are POE, glass fiber and molybdenum disulfide, and the quality of the glass fiber is 20% of POE. The mass of molybdenum disulfide is 1.0% of the mass of POE. as attached Figure 4 shown.

[0062] The bolt ball head 2 is sleeved on one end of the bolt body 1, and the external connecting sleeve 3 is connected with the movable sleeve of the bolt ball head, and the external connecting sleeve 3 is connected with the separating shift fork body of the gearbox.

[0063] A groove 4 is arranged on the top end of the bolt ball head 2 . Lubricating oil can be stored in the groove to improve the lubricating effect and reduce wear and noise.

[0064] One end of the bolt body 1 where the bolt ball head 2 is installed is provided with a boss plane 15. , When the transmission fork support bolt is impacted by an external force due to the operation of ...

Embodiment 3

[0078] A gearbox separation shift fork support bolt with a ball head made of POE material, the ball head 2 of the bolt is POE, glass fiber and molybdenum disulfide, the quality of the glass fiber is 22% of POE, and the two The mass of molybdenum sulfide is 1.8% of the mass of POE. as attached Figure 5 shown.

[0079] The bolt ball head 2 is sleeved on one end of the bolt body 1, and the external connecting sleeve 3 is connected with the movable sleeve of the bolt ball head, and the external connecting sleeve 3 is connected with the separating shift fork body of the gearbox.

[0080] The top end of the bolt ball head 2 is a planar structure 14 , and after the bolt ball head 2 is assembled with the outer connecting sleeve 3 , a cavity can be formed between the planar structure 14 and the outer connecting sleeve 3 .

[0081] The bolt ball head 2 includes a body portion 5 and a connection portion 6 , the body portion 5 and the connection portion 6 are integrally structured, and...

Abstract

The invention discloses a gearbox release shifting fork supporting bolt with a ball head part made of a POE material and a preparation method of the gearbox release shifting fork supporting bolt. Theball head part of the bolt takes POE, or POE and glass fiber, or POE, glass fiber and molybdenum disulfide as raw materials of the ball head part of the bolt, and the ball head part of the bolt is connected to a bolt body through an injection molding process. The gearbox release shifting fork supporting bolt with the ball head part made of the POE material is simple in structure and capable of effectively improving abrasion resistance and strength of the gearbox release shifting fork supporting bolt, prolonging the service life of the gearbox release shifting fork supporting bolt, reducing maintenance frequency, effectively reducing noise in use, reducing weight and meeting the requirement for light weight of an automobile.

Description

technical field [0001] The invention belongs to the technical field of fasteners for vehicles, and in particular relates to a transmission fork support bolt whose spherical head is made of POE material and a preparation method thereof. Background technique [0002] In the gearbox structure, when the gearbox controls the working conditions of the car, it needs to control the action of the gearbox release fork, and the gearbox release fork is in contact with the support bolt of the release fork. When the gearbox is working, the two Relative movement occurs. In the prior art, the support bolts of the release shift fork are made of metal materials. In this way, when the gearbox is working, the release shift fork and the support bolts are in metal-to-metal contact, which makes the noise loud, and the metal to metal cannot be reliably lubricated, resulting in The amount of wear is large, and the service life of the support bolts is short. If they are used for a period of time wit...
