Abstract
The utility model discloses a shift fork of shifting reverses gear, including reversing gear shift fork (1) and reversing gear selector fork (2), reverse gear selector fork (1) for the forging semicircular prong (1a) and declutch shift shaft mounting hole (1b), outside declutch shift shaft mounting hole (1b) is located prong (1a), and the flat shape of axis of the axis of declutch shift shaft mounting hole (1b) and prong (1a), reverse gear selector fork (2) add for steel sheet punching machine, weld welded fastening together with the shift fork that reverses gear (1) through argon arc. The product uniformity is good, toughness is good, the compact structure, qualification rate high, has avoided traditional casting defects to the influence of machining precision, has improved the qualification rate of product and has used intensity.
Description
Technical field
The utility model relates to speed changer component structural, is specifically related to a kind of reverse gear shifting fork.
Background technique
Existing reverse gear shifting fork is due to complex structure, and usually adopt spheroidal graphite cast iron casting, its method is that spheroidal graphite cast iron molten metal is poured into casting mold, solidifies the foundry goods of rear acquisition definite shape, size, composition, structure and properties.
The subject matter adopting spheroidal graphite cast iron casting to exist is: (1) has loose, not fine and close, is not suitable with important parts; (2) blank size conformity is poor, and comparatively large to following process Accuracy, conforming product rate is low; (3) poor toughness is not shock-resistant, easy brittle failure.
Model utility content
The utility model purport provides the reverse gear shifting fork that a kind of good product consistency, good toughness, compact structure, up-to-standard rate are high.
For this reason, the technological scheme that the utility model adopts is: a kind of reverse gear shifting fork, comprise back fork and the selector fork that reverses gear, the described selector fork that reverses gear is forging, comprise semicircular prong and declutch shift shaft mounting hole, described declutch shift shaft mounting hole site is outside prong, and the axis of declutch shift shaft mounting hole and the flat shape of the axis of prong; The described selector fork that reverses gear is that punching of the steel plate machine adds part, together with back fork is welded and fixed by argon arc welding.
Be preferably, the weld seam that described back fork welds with the selector fork that reverses gear totally two, ensure the reliability of welding.
Further, described back fork and the selector fork that reverses gear all adopt 45 steel, and ensure the quality of products, cost is low.
The beneficial effects of the utility model: reverse gear shifting fork is divided into back fork and the selector fork two-part that reverse gear, welds together again after processing respectively.Back fork belongs to important parts, under the effect of forging equipment and work (mould) tool, makes blank or ingot casting produce plastic deformation, thus obtains certain physical dimension, shape and quality, dense structure; Blank size conformity is better, and little to following process Accuracy, conforming product rate is high.The selector fork that reverses gear is that punching of the steel plate machine adds part, good product consistency.This configuration avoids the impact of casting defect on machining accuracy, improve up-to-standard rate and the working strength of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Reverse gear shifting fork as shown in Figure 1, primarily of back fork 1 and selector fork 2 two-part composition that reverses gear.
Reverse gear selector fork 1 for forging, and comprise semicircular prong 1a and declutch shift shaft mounting hole 1b, declutch shift shaft mounting hole 1b is positioned at outside prong 1a, and the flat shape of axis of the axis of declutch shift shaft mounting hole 1b and prong 1a.The selector fork 2 that reverses gear adds part for punching of the steel plate machine, together with back fork 1 is welded and fixed by argon arc welding.
Preferably, the weld seam 3 that back fork 1 welds with the selector fork 2 that reverses gear totally two, two weld seams 3 are parallel to each other.
In addition, back fork 1 and the selector fork 2 that reverses gear all adopt 45 steel.
Claims (2)
1. a reverse gear shifting fork, it is characterized in that: comprise back fork (1) and the selector fork that reverses gear (2), the described selector fork that reverses gear (1) is forging, comprise semicircular prong (1a) and declutch shift shaft mounting hole (1b), described declutch shift shaft mounting hole (1b) is positioned at prong (1a) outward, and the flat shape of axis of the axis of declutch shift shaft mounting hole (1b) and prong (1a); The described selector fork that reverses gear (2) adds part for punching of the steel plate machine, together with back fork (1) is welded and fixed by argon arc welding; The weld seam (3) that described back fork (1) welds with the selector fork that reverses gear (2) totally two, and two weld seams are parallel to each other.
2. according to reverse gear shifting fork according to claim 1, it is characterized in that: described back fork (1) and the selector fork that reverses gear (2) all adopt 45 steel.
