Description

Lightweight high-strength shifting fork
Technical Field
The utility model relates to an automobile spare and accessory part technical field specifically is a lightweight high strength shift fork.
Background
The shifting fork is used for pushing a gear of the transmission and changing the position of the gear, and the gear ratio is changed by changing the position of the gear so as to achieve the purpose of speed change. The gears of the transmission are loaded on a main shaft and a secondary shaft, and the gear ratio can be changed by pushing the main shaft and the secondary shaft to move forwards or backwards through a shifting fork. Therefore, different processes or sizes of the shifting fork have different speed changing effects, and simply speaking, the structure of the shifting fork has a very important relationship with the effect of the transmission.
The most easily worn place of the shifting fork is the contact part of the shifting fork and the gear ring groove, because the gear rotates at high speed, the shifting fork does not rotate, the shifting fork is worn or has insufficient strength, the gear can not be hung, gear shifting can occur, and even the shifting fork can be broken, thereby affecting the safety performance of the automobile in the driving process.
Disclosure of Invention
An object of the utility model is to provide a lightweight high strength shift fork has high strength and wear resistance, can improve the security performance of car in the driving process, has solved the problem among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme:
a light-weight high-strength shifting fork comprises a body and a shifting fork working surface, wherein a main mounting hole and an auxiliary hole are formed in the upper end of the body, the auxiliary hole is formed below the main mounting hole, the shifting fork working surface is located at the lower end of the body and comprises a first shifting fork foot and a second shifting fork foot, and a semicircular arch fork opening is formed between the first shifting fork foot and the second shifting fork foot; the size of body along thickness direction is less than the shift fork working face, the body with the shift fork working face is connected the face through being mirror symmetry setting and is closed as an organic whole, the body is close to the junction of second shift fork foot and is equipped with the first strengthening rib that is the line type, one section that first strengthening rib is close to main mounting hole, auxiliary hole is equipped with the second strengthening rib that is the three horn shapes of slope.
Further, the body and the shifting fork working face are made of aluminum alloy.
The auxiliary hole is arranged below the main mounting hole, so that when the guide rod is stirred during the operation of the shifting fork, the positioning is more stable, and the action accuracy is improved; the body is designed to be thinner than the working surface of the shifting fork, when the working surface of the shifting fork is attached to the working surface of the synchronous gear ring, lubricating oil can smoothly enter the working surface of the shifting fork through the connecting surface, and then a pressure oil film is formed for protection, so that the surface of the working surface of the shifting fork is prevented from being abraded, and the service life of the whole body is prolonged; through setting up first strengthening rib and second strengthening rib, can improve the holistic rigidity of shift fork and intensity, simultaneously because the position that does not set up the strengthening rib adopts the aluminum alloy material for fretwork design and overall structure, realizes holistic lightweight. The utility model provides a lightweight high strength shift fork has high strength and wear resistance, can improve the security performance of car in the driving process, has solved the problem among the prior art.

Fig. 2 is a sectional view B-B of fig. 1.
In the figure: 10. a body; 20. a shift fork working surface; 30. a connecting surface; 11. a main mounting hole; 12. an auxiliary hole; 13. a first reinforcing rib; 14. a second reinforcing rib; 21. a first fork leg; 22. a second fork foot.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a light-weight high-strength shifting fork, including a body 10 and a shifting fork working surface 20, wherein the upper end of the body 10 is provided with a main mounting hole 11 and an auxiliary hole 12, the auxiliary hole 12 is disposed below the main mounting hole 11, the shifting fork working surface 20 is located at the lower end of the body 10, the shifting fork working surface 20 includes a first shifting fork leg 21 and a second shifting fork leg 22, and a semicircular arched fork opening is formed between the first shifting fork leg 21 and the second shifting fork leg 22; the size of body 10 along thickness direction is less than shift fork working face 20, and body 10 closes as an organic whole through being the connection face 30 that mirror symmetry set up with shift fork working face 20, and body 10 is close to the junction of second shift fork foot 22 and is equipped with the first strengthening rib 13 that is the line type, and first strengthening rib 13 is close to main mounting hole 11, one section of auxiliary hole 12 is equipped with the second strengthening rib 14 that is the slope triangle-shaped.
Further, the body 10 and the fork face 20 are made of aluminum alloy.
The auxiliary hole is arranged below the main mounting hole, so that when the guide rod is stirred during the operation of the shifting fork, the positioning is more stable, and the action accuracy is improved; the body is designed to be thinner than the working surface of the shifting fork, when the working surface of the shifting fork is attached to the working surface of the synchronous gear ring, lubricating oil can smoothly enter the working surface of the shifting fork through the connecting surface, and then a pressure oil film is formed for protection, so that the surface of the working surface of the shifting fork is prevented from being abraded, and the service life of the whole body is prolonged; through setting up first strengthening rib and second strengthening rib, can improve the holistic rigidity of shift fork and intensity, simultaneously because the position that does not set up the strengthening rib adopts the aluminum alloy material for fretwork design and overall structure, realizes holistic lightweight. The utility model provides a lightweight high strength shift fork has high strength and wear resistance, can improve the security performance of car in the driving process, has solved the problem among the prior art.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
