Abstract
The utility model relates to a reverser shifting fork, and belongs to the technical field of motor tricycle out-hanging gearboxes. The reverser shifting fork comprises a shifting fork rotary head. A locating supporting point and a locating baffle block are arranged on the shifting fork rotary head. The reverser shifting fork is characterized in that a shifting arm is arranged at the left end of the shifting fork rotary head, the bottom portion of the left end of the shifting arm is fixed with a shifting pivot, and a shifting sliding block is installed on the shifting pivot. The reverser shifting fork is simple in structure. Compared with the prior art, the reverser shifting fork has the advantages that the mode that an existing shifting fork needs to undergo secondary connecting conversion is changed, the transmission mode that a gear-shifting shaft is connected with the shifting fork rotary head is adopted, the rotation angle of a gear-shifting pedal when the gear-shifting pedal moves forward or backward is guaranteed, and gear shifting is guaranteed to be in place at one time.
Description
Technical field
The utility model relates to a kind of reverse gear selector fork, belongs to the plug-in gearbox technical field of motor tricycle.
Background technique
At present, the plug-in gearbox of motor tricycle (reverse gear) in use, stir change pedal earlier, the gearshift axle of change pedal below will drive little shift fork and swing, little shift fork drives shift fork again, thereby make the connection tooth that is installed on the splined shaft and corresponding driven tooth combination, finally finish gearshift work.From above-mentioned working procedure, be not difficult to find out, existing reverse gear is after stirring the gearshift springboard, and selector fork will connect conversion through secondary, thereby the rotation angle when making change pedal forward or backward is too big, generally at 40～60 °, can not well once dial retaining sometimes and put in place.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of reverse gear selector fork is provided, and it is simple in structure, has guaranteed the rotation angle when change pedal forward or backward, guarantees once to dial retaining and puts in place.
Reverse gear selector fork described in the utility model, comprise the shift fork rotary head, the shift fork rotary head is provided with location fulcrum and position block, and it is characterized in that: shift fork rotary head left end is provided with moving arm, pivot is fixedly stirred in moving arm left end bottom, is equipped with and stirs slide block stirring pivot.
The preferred described slider bottom of stirring of the utility model is rectangle structure.
Wherein, be arcuate structure with described moving arm further, arc angle is the right angle.
Connection is installed for convenience, offers attachment hole in described shift fork rotary head Vertical direction.The form of attachment hole can be gear type, also can be the rectangular opening formula, can also be spline.
During use, the gearshift axle that selection matches with attachment hole, the shift fork rotary head is installed on the gearshift axle, offering in conjunction with tooth and stirring the chute that slide block matches, will stir slide block then and be arranged in the chute, when the gearshift axle rotates, driving the shift fork rotary head rotates, successively rotatory force is passed to by moving arm and stir pivot and stir slide block, make at last in conjunction with tooth and under the effect of stirring slide block, slide, finally finish gearshift work.
Compared with prior art, the utlity model has following beneficial effect:
By the utility model, it is simple in structure, compared with prior art, change selector fork and will connect the mode of changing through secondary, a kind of drive that directly adopts the gearshift axle to be connected with the shift fork rotary head has been guaranteed the rotation angle when change pedal forward or backward, guarantees once to dial to keep off and puts in place.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the reverse gear selector fork, comprise shift fork rotary head 6, be respectively arranged with location fulcrum 5 and position block 4 on the shift fork rotary head 6, shift fork rotary head 6 left ends are provided with moving arm 3, moving arm 3 is arcuate structure, arc angle is the right angle, and pivot 2 is fixedly stirred in moving arm 3 left ends bottoms, is equipped with and stirs slide block 1 stirring pivot 2, stirring slide block 1 bottom is rectangle structure, offers attachment hole 7 on shift fork rotary head 6 Vertical direction.
During use, as shown in Figure 3, Figure 4, the gearshift axle 9 that selection matches with attachment hole 7, general attachment hole 7 adopts splines, conveniently with gearshift 9 cooperates.Shift fork rotary head 6 is installed on the gearshift axle 9, offering in conjunction with tooth 8 and stirring the chute 10 that slide block 1 matches, to stir slide block 1 then is arranged in the chute 10, when gearshift axle 9 rotates, driving shift fork rotary head 6 rotates, successively rotatory force is passed to by moving arm 3 and stir pivot 2 and stir slide block 1, make at last in conjunction with tooth 8 and under the effect of stirring slide block 1, slide, finally finish gearshift work.
By present embodiment, the rotation angle of change pedal forward or backward the time just is about 18 °.
