Abstract
The present invention relates to a hand operated gearshift mechanism which comprises a base which is provided with an accommodating cavity and a slide cavity, and a gearshift arm, a gearshift lever and a driving plate which are mutually hard connected, wherein the driving plate is provided with a sliding chute, and a positioning bolt is fixed to a shifting fork shaft through the sliding chute; the shifting fork shaft is connected with a shifting fork, and both the shifting fork shaft and the shifting fork are arranged in the slide cavity; the gearshift arm, gearshift lever and the driving plate are arranged in the accommodating cavity. Thus, the present invention has the advantages of manual gearshift, simple structure, clear gear and small impact of gearshift; an operating lever do not return to the initial position after each operation.
Description
Technical field
The present invention relates to a kind of hand operated gearshift mechanism, especially a kind of hand operated gearshift mechanism that is applicable to motor bike.
Background technology
Along with development of times, the development of motor bike also is with rapid changepl. never-ending changes and improvements.But the gearshift mechanism of motor bike all is the foot-propelled gear shift at present.As Fig. 1 with shown in 2, be the front elevation and the lateral plan of the structure of common speed change drum-type gearshift.The user handles gear shifting rod 91 and stirs variable speed drum 92, by rotating the axial motion of the cam profile control shift fork 93 on the variable speed drum 92, changes thereby the variable gear that connects with shift fork 93 is meshed, and reaches the purpose of shift.
Though it can realize many gears (at present maximum is seven) gear shift, each operation back joystick is got back to initial position under the effect of pull back spring, only suitable pin operation, and complex structure, and parts are many, and the working accuracy height is not suitable for manual variable block.
Summary of the invention
The objective of the invention is to realize a kind of hand operated gearshift mechanism, simple in structure, each operation back joystick is not got back to initial position, and gear is clear, and shift impacts little.
For achieving the above object, the invention provides a kind of hand operated gearshift mechanism, comprise a pedestal, this pedestal has a containing cavity and a sliding cavity, mutual hardwired gear shift arm, Shift lever and group plate, this baffle plate has chute, and a dowel bolt is fixed on the declutch shift shaft by described chute, this declutch shift shaft connects a shift fork and all places in the described sliding cavity, and described gear shift arm, Shift lever and group plate place in the described containing cavity.
Be connected with axle sleeve and spring with group plate junction on the described Shift lever with buffering usefulness.Described declutch shift shaft has jagged limited impression, and described pedestal has spacing cavity volume, built-in spring of this spacing cavity volume and spacing ball, and this spacing ball and described limited impression offset.Described declutch shift shaft has the gear groove, and described pedestal has the gear cavity volume, the built-in gear position sensor of this cavity volume, and this gear position sensor and described gear groove offset.Described declutch shift shaft has two gear grooves, and described pedestal has two gear cavity volumes.Described gear shift arm, Shift lever and group plate are connected firmly by spline or welding.
Therefore, the present invention has realized hand shift, and simple in structure, and each operation back joystick is not got back to initial position, and gear is clear, and shift impacts little.
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.

Fig. 2 is the lateral plan of the common speed change drum-type of background technology gearshift.
Fig. 3 is the birds-eye view of the manual portion of hand operated gearshift mechanism of the present invention.
Fig. 4 is that hand operated gearshift mechanism of the present invention is manually deployed the structural representation in pedestal.
Fig. 5 is the cutaway view of hand operated gearshift mechanism Fig. 4 A-A line of the present invention.
The specific embodiment
As Fig. 3 with Figure 5 shows that the scheme drawing of the manual portion of the present invention and the cutaway view of Fig. 4 A-A line.Manually the gear shift arm 10 of portion 1, Shift lever 11 and group plate 12 are connected firmly by spline mutually, also can weld.In order to cushion shifting shock, have axle sleeve 13 and spring 14 with group plate 12 junctions on the Shift lever 11.Dial plate 12 and have chute 120, dowel bolt 15 is fixed on the declutch shift shaft 16 by chute 120, and this declutch shift shaft 16 has jagged gear groove 161 and limited impression 160.
Be illustrated in figure 4 as the present invention and manually deploy structural representation in pedestal.Pedestal 2 has a containing cavity 20 and a sliding cavity 21, and the top of sliding cavity 21 has a spacing cavity volume 22 and two gear cavity volumes 23.Have spring 220 and spacing ball 221 in the spacing cavity volume 22.Gear cavity volume 23 is built-in with a gear position sensor 230.Manually the gear shift arm 10 of portion 1, Shift lever 11 and group plate 12 place in the containing cavity 20 of pedestal 2, and declutch shift shaft 16 connects shift forks 17 and all places in the sliding cavity 21.Gear position sensor 230 offsets with gear groove 161, and spacing ball 221 offsets with limited impression 160.
When work, the user handles gear shift arm 10, and its axial line around Shift lever 11 is rotated, and related Shift lever 11 and group plate 12 rotate around the axial line of Shift lever 11 simultaneously.The chute 120 of dialling plate 12 drives dowel bolt 15, dowel bolt 15 moves in chute 120, make and the axial-movement of the fixing fork axle 16 of dowel bolt 15, thereby the variable gear engagement that connects with shift fork 17 is changed, reach the purpose of shift along sliding cavity 120.In order to make gear feel clear, the speed change tooth is corresponding with the sawtooth of limited impression 160, and during transforming gear, spacing ball 221 moves to another sawtooth from a sawtooth of limited impression 160 just.Equally, gear groove 161 is also corresponding with the gear positions that needs show with gear position sensor 230.Axle sleeve 13 on the Shift lever 11 is the impact when cushioning gear shift during with spring 14.
Therefore, the present invention has realized hand shift, and simple in structure, and each operation back joystick is not got back to initial position, and gear is clear, and shift impacts little.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
