For inverted "convex" shape, the lower end of the yoke bar is fixedly attached to middle position at the top of the circular arc of shift fork arm, the yoke bar
Upper end is threaded, and nut is combined on the screw thread, is equipped at a certain distance from the lower part of the screw thread perpendicular to yoke bar
The through-hole of axis, dismountable fixed stop is equipped in the through-hole, and the length of the fixed stop is greater than the diameter of yoke bar；
The direction of the through-hole is consistent with the plane where the circular arc of shift fork arm.
Preferably, the lower end of the yoke bar is welded on middle position at the top of the circular arc of shift fork arm.
Preferably, the cornerite between the two sides at the circular arc both ends of the shift fork arm is 90 °.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model by the lower end of yoke bar connection be in arc structure shift fork arm, improve stir power by
Power face, it is ensured that stir that power is steadily reliable, and using effect is significant, be worthy to be popularized.
2, the lower end of yoke bar is welded on the center top of shift fork arm by the utility model, improves the structure of entire shift fork
Intensity improves the service life of shift fork.
3, the cornerite between the two sides at the circular arc both ends of shift fork arm is to be set as 90 ° by the utility model, can be primary
Machine-shaping 4, the craftsmanship of processing and manufacturing is improved, processing and manufacturing is facilitated, improves production efficiency.
4, yoke bar, can be fixed in shift fork axle by dismountable fixed stop in the utility model and nut cooperation,
The reliability of work is improved, and facilitates handling.
5, the utility model has the advantages that compact-sized, at low cost, good manufacturability, manufacture are easy to assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic side view of Fig. 1.
In figure: 1- yoke bar, 2- shift fork arm, 3- screw thread, 4- nut, 5- fixed stop, 11- through-hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1 and Fig. 2, a kind of shift fork, including yoke bar 1 and shift fork arm 2 are please referred to, the yoke bar 1 is in cylindrical structure,
The shift fork arm 2 is in one section of arc structure, and the cross sectional shape of the shift fork arm 2 is inverted "convex" shape, the lower end of the yoke bar 1
It is fixedly attached to middle position at the top of the circular arc of shift fork arm 2, the upper end of the yoke bar 1 is threaded 3, on the screw thread 3
It is combined with nut 4, the through-hole 11 perpendicular to 1 axis of yoke bar, the through-hole 11 are equipped at a certain distance from the lower part of the screw thread 3
In be equipped with dismountable fixed stop 5, the length of the fixed stop 5 is greater than the diameter of yoke bar 1；The direction of the through-hole 11
It is consistent with the plane where the circular arc of shift fork arm 2.
The lower end of the yoke bar 1 is welded on middle position at the top of the circular arc of shift fork arm 2.
Cornerite between the two sides at the circular arc both ends of the shift fork arm 2 is 90 °.
Working principle: when manufacturing the shift fork of the utility model, the upper end of yoke bar 1 first can be processed into screw thread and through-hole
11, then the lower end of yoke bar 1 is welded on to middle position at the top of the circular arc of shift fork arm 2；Use a kind of shift fork of the utility model
When, the upper end of yoke bar 1 can be passed through shift fork axle can be in yoke bar due to there is the limit of the fixed stop 5 in through-hole 11
Threaded upper ends 3 on screw nut, yoke bar 1 is fixed in the shift fork axle of shifting system or clutch system, works as shift fork axle
