Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Fig. 2~5 show some embodiments according to the present utility model.
In one embodiment, a kind of transmission reverse gear pull-fork assembly, including back fork ontology 1, the back fork sheet
Straight pin 4 is welded on body 1, the setting that the back fork ontology 1 can be rotated by straight pin 4 is in shifting support base
On, when the back fork ontology 1 is mounted on shifting support base, carried out by being caught in snap ring in one end of straight pin 4
Back fork ontology 1 along cylindrical pin to axial limiting.
In one embodiment, one end for closing on straight pin 4 of the back fork ontology 1 is provided with U-type groove 5, is reversing gear
In shift process, by shifting gears, the shifting block that reverses gear that head is stirred is acted in the U-type groove 5, to drive the back fork ontology 1
Rotation.
In one embodiment, described to reverse gear as shown in Fig. 2, the transmission reverse gear pull-fork assembly further includes the sliding block 2 that reverses gear
On the back fork ontology 1, the sliding block 2 that reverses gear is located at separate on back fork ontology 1 for the setting that sliding block 2 can rotate
One end of straight pin 4, it is described reverse gear sliding block 2 for push reverse gear tooth shaft to sliding.
Wherein, as shown in Figure 2-5, the rotation that the sliding block 2 that reverses gear includes slider body 21 and is installed on slider body 21
Shaft 22, the slider body 21 are configured in the sliding slot 7 to reverse gear on tooth slip base when reversing gear and shifting gears, for pushing the tooth that reverses gear
Axial sliding, the rotary shaft 22 are equipped with card slot 23, when the sliding block 2 that reverses gear is mounted on back fork ontology 1, the rotation
It is arranged with snap ring 3 at card slot 23 in shaft 22, with the axial limiting for reversing gear sliding block 2 along rotary shaft axial direction.
In one embodiment, the center position of slider body 21 is arranged in the rotary shaft 22, to guarantee the sliding block 2 that reverses gear
Rotational stability, side wall of the sliding block 2 during rotation with sliding slot 7 that avoid reversing gear collide.
In one embodiment, as shown in figure 4, the slider body 21 isType block.
In one embodiment, as shown in figure 5, the width of the sliding slot 7 is slightly larger than the width of slider body 21.
Design of part in the utility model is irregular design, is manufactured using stamping-welded mode,
And heat treatment process is carried out after welding.
It has been observed that the sliding block that reverses gear in existing back fork component is installed on back fork ontology, it is existing
Back fork component for reverse gear tooth shaft to sliding shift when, back fork ontology rotates under the stirring for the shifting block that reverses gear
Movement, as back fork ontology rotates together, the sliding block while being configured at of reversing gear reverses gear on tooth slip base the sliding block that reverses gear
In sliding slot 7, as shown in Figure 1.Under the rotary action for the sliding block that reverses gear, the side wall of sliding slot 7 is pressed in the side for the sliding block that reverses gear, so that
The axial sliding of the tooth 6 that reverses gear can be pushed, during the slipper push that reverses gear reverses gear the axial movement of tooth 6, the pose for the sliding block that reverses gear
Change at any time relative to sliding slot 7, and in the pose for the sliding block that reverses gear relative in 7 change procedure of sliding slot, the side wall pair of the sliding slot 7
The pose variation of sliding block of reversing gear is hindered, and the sliding block pose variation that causes to reverse gear has some setbacks, so as to cause reverse gear shift gears when appearance
It is also easy to produce bite sense.
The setting that sliding block 2 can rotate of reversing gear in the back fork component of the utility model on back fork ontology 1,
For the back fork component of the utility model when shifting gears for tooth shaft of reversing gear to sliding, back fork ontology 1 is in the shifting block that reverses gear
It stirs down and rotates, as back fork ontology 1 rotates together, described reverse gear while being configured at down sliding block 2 sliding block 2 that reverses gear
It keeps off in the sliding slot 7 on tooth slip base, as shown in Figure 5.
Under the action of the sliding block 2 that reverses gear is rotated together with back fork ontology 1, sliding slot 7 is pressed in the side for the sliding block 2 that reverses gear
Side wall so that the axial sliding of the tooth 6 of reversing gear can be pushed, during this due to it is described reverse gear sliding block 2 can around itself
Rotary shaft 22 rotate so that reverse gear shift gears when, the pose of the sliding block 2 that reverses gear is relative to the sliding slot 7 to reverse gear on tooth slip base
It is able to maintain constant, state (as shown in Figure 5) in a vertical shape, the pose of the sliding block 2 in sliding slot 7 that reverse gear do not change always,
There is no obstruction disturbing factor of the chute wall to sliding block pose variation of reversing gear therefore can by the use of the utility model
The bite sense reversed gear when shifting gears is reduced, shift quality is improved.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
