Embodiment 1

[0026] Example 1 as Figure 1~3 As shown, the structure of the shift fork of the automobile transmission includes a shift fork 4 of the automobile gearbox and a floating and replaceable shift block of the shift fork of the automobile gearbox. The anti-falling blocking piece 3 at the tail, wherein the shift block body is a T-shaped component whose tail is smaller than the head end, which includes a metal skeleton 11 and a wear-resistant layer 12 coated on the metal skeleton, and the anti-falling blocking piece is a metal sheet, One end is embedded in the center of the rear end face of the shifting block body, and the other end protrudes radially from the outer peripheral edge of the tail of the shifting block body. When assembling the floating replaceable shift block with the shift fork 4 of the automobile gearbox, adjust the included angle between the anti-falling retainer and the end face of the shift block body so that it passes through the round hole bracket provided on the...

Embodiment 2

[0027] Example 2 as Figure 4 As shown, the floating structure of the shift fork of the automobile gearbox is similar to that of Embodiment 1. However, the anti-falling blocking plate 3' adopted in the replaceable shifting block of the automobile gearbox in this embodiment is a T-shaped metal member, the middle part of which is embedded in the center of the rear end face of the shifting block body 1, and the two ends are respectively moved along the symmetrical radial direction. The outer peripheral edge of the tail of the shifting block body protrudes. When assembling the shift block with the shift fork of the automobile gearbox, adjust the angle between the two ends of the anti-falling block to make it pass through the fork hole set on the shift fork, and then restore the angle between the two ends of the anti-falling block to the original state That's it.

Embodiment 3

[0028] Example 3 as Figure 5 As shown, the shift fork structure of the automobile gearbox is similar to that of Embodiment 1. However, the clip mechanism selected in the replaceable shifting block of the automobile gearbox in this embodiment is an anti-falling retaining ring 6, which is integrally arranged with the shifting block, and its end is a retractable part 62, and an outer ring 6 is arranged on the retractable part. An annular rib 61 whose diameter is greater than the inner diameter of the round hole stent. The extrusion force of the anti-falling retaining ring is generally above 20N.

Abstract

The invention relates to an automobile gearbox shifting fork structure and a floating replaceable shifting block thereof. An automobile gearbox shifting fork and the shifting block thereof are split-type arrangement; the head of the shifting block is an expansion structure; an axle journal part is installed in a circular slotted-hole support and can freely rotate, and the tail part thereof is provided with a fastener mechanism which is at least one of a dropping-proof baffle ring, a dropping-proof baffle plate, a clamping spring, a cotter pin and a round pin with a fastener. The floating replaceable shifting block of the automobile gearbox shifting fork has simple and compact structure, convenient installation and replacement and low manufacturing cost, and can lead the automobile gearbox shifting fork to have good service performance and replaceability. The automobile gearbox shifting fork structure and the floating replaceable shifting block thereof can be widely applied to gearboxes of various motor vehicles or other vehicles.

Description

technical field [0001] The invention relates to a shift fork structure of an automobile gearbox, in particular to a shift fork structure of an automobile gearbox and a floating replaceable shift block of the shift fork of the automobile gearbox. Background technique [0002] Automobile gearbox shift fork is an important component in automobile gearbox. If it is damaged while the car is running, it will easily lead to traffic accidents, and even cause the tragedy of car crash. At present, the shift fork of the automobile gearbox is generally installed in the automobile gearbox through a shift block integrally arranged with the shift fork. This type of shifting block is inconvenient to install, and if the shifting block is worn or damaged, the shift fork of the automobile transmission needs to be replaced as a whole, which is inconvenient to operate and expensive. Contents of the invention [0003] The object of the present invention is to propose a kind of car gearbox shif...
