In addition, the gearshift of described manual transmission further comprises: guide finge, and it is fixed on described gearbox case; Steering channel, it is arranged on the base portion of described selector fork, and described guide finge is inserted described steering channel, and described steering channel is for making described gearshift chosen axis along predetermined gearshift motion of defect modes; And retainer, it is arranged on the end of described steering channel and the end of described steering channel is corresponding with the sense of rotation end around axis of described gearshift chosen axis, in the scope contacting, contacts with described guide finge for one of Caused by Sloping Surfaces region in described moving body and described sense of rotation.
In addition,, in the gearshift of described manual transmission, the maximum radius of the described cam face centered by the axis of described gearshift chosen axis is set to the maximum radius that is greater than the described steering channel centered by the axis of described gearshift chosen axis.
According to a form of the present invention, when moving body is extruded to gearshift chosen axis, the cam face of cam applies operational load to this gearshift chosen axis, this cam face has: domatic region on axial direction, in this region, from the axial direction neutral gear position of this gearshift chosen axis toward each two of this cam face reverse axial direction ends, larger to the distance of the axis of this gearshift chosen axis.Therefore, in the situation that this gearshift chosen axis moves along axis from neutral gear position to another location, this elastomer that this moving body is expressed to cam face is compressed to the distance in domatic region the axial direction of cam face according to the axis from this gearshift chosen axis, and applies the operational load on axial direction to this gearshift chosen axis.In addition, on this axial direction, domatic region is concave, and wherein neutral gear position is recess, makes this gearshift chosen axis turn back to axial direction neutral gear position by this elastomeric repulsive force.On the other hand, the cam face that applies the cam of operational load to this gearshift chosen axis when this moving body pushes the cam face of cam also has: domatic region in sense of rotation, in this region, neutral gear position the sense of rotation of gearshift chosen axis is toward each in two of this cam face reverse sense of rotation ends, larger to the distance of the axis of gearshift chosen axis; And sense of rotation Caused by Sloping Surfaces region, in this region and sense of rotation, domatic region is continuous, and in this region, from sense of rotation the border in domatic region toward each in two of cam face reverse sense of rotation ends, less to the distance of the axis of gearshift chosen axis.Therefore, gearshift chosen axis in the situation that rotate from neutral gear position around axis in the scope that moving body contacts with one of domatic region in sense of rotation, the elastomer that moving body is expressed to cam face is compressed to the distance in domatic region the sense of rotation of cam face according to the axis from gearshift chosen axis, and the operational load in sense of rotation is applied to gearshift chosen axis.In addition, in sense of rotation, domatic region is concave, and wherein neutral gear position is recess, and the chosen axis that makes to shift gears turns back to sense of rotation neutral gear position by elastomeric repulsive force.In addition, in the situation that gearshift chosen axis turns to around axis the position that moving body contacts with one of sense of rotation Caused by Sloping Surfaces region, can be by the elastomeric repulsive force quick rotation gearshift chosen axis in the downward direction in sense of rotation Caused by Sloping Surfaces region being applied by sense of rotation Caused by Sloping Surfaces region.Therefore,, when the set positions above in the downward direction in sense of rotation Caused by Sloping Surfaces region is shift position, can will shift gears chosen axis quick rotation to shift position by the elastomeric repulsive force being applied by sense of rotation Caused by Sloping Surfaces region.In addition, can freely set and there is on axial direction the cam face in domatic region and sense of rotation Caused by Sloping Surfaces region in domatic region, sense of rotation to the distance of the axis of gearshift chosen axis, thereby can freely set the axial direction of gearshift chosen axis and the operational load in sense of rotation.Therefore, can by single cam face apply simultaneously gearshift chosen axis axial direction on operational load and the operational load in sense of rotation, and can freely set these operational loads, thereby can combine the chosen axis that makes to shift gears in axial direction and sense of rotation, turn back to neutral gear position.

Embodiment
The mode of execution of the gearshift of manual transmission of the present invention is described below with reference to accompanying drawings.Fig. 1 is the planimetric map that an example of the manual transmission that the gearshift of present embodiment is applied to is shown.This manual transmission has 5 and moves forward gear and 1 mobile gear backward.The gear of this manual transmission is contained in gearbox case 1.This gearbox case 1 consists of clutch housing, gearbox case, gear shift cover such as being connected to motor etc.The gearshift of present embodiment is installed on gearshift shell 2, and gearshift shell 2 is assembled to the back center position of this speed changer 1.In the vertical direction of the plane with this figure, gearshift chosen axis 3 is through the center portion of this gearshift shell 2 shown in this Fig.In addition, for the selector 4 of moving gear shift chosen axis 3 on the axial direction at gearshift chosen axis 3 with for the speed change lever 5 that the axis around gearshift chosen axis 3 rotates gearshift chosen axis 3, be assembled to the position of stretching out to outside from the gearshift shell 2 of gearshift chosen axis 3.
In the present embodiment, gearshift chosen axis 3 for example along the steering channel 13 shown in Fig. 7 according to gearshift motion of defect modes.The steering channel 13 of present embodiment has a cannelure and three transverse grooves.This cannelure, corresponding to the axial direction of gearshift chosen axis 3, and is also referred to as choice direction conventionally.On the other hand, transverse groove is corresponding to the sense of rotation of axis around gearshift chosen axis 3, and is conventionally also referred to as gearshift direction.Therefore, this cannelure is neutral gear position.In addition, in the middle of the steering channel 13 of Fig. 7, upper right is the shift position of the first gear, upper left is the shift position of the second gear, right on above-below direction is the shift position of the 3rd gear, left on above-below direction is the shift position of the 4th gear, and bottom right is the shift position of the 5th gear, and lower-left is the shift position that moves backward (reversing) gear.Therefore, put it briefly, variable speed operation will move (selection) gearshift chosen axis 3 on axial direction, and rotate (switching) gearshift chosen axis 3 around this axis.
Fig. 2 is the II-II sectional view of Fig. 1, and it illustrates the left side of the gearshift of Fig. 1, and Fig. 3 is the rear view of the gearshift of Fig. 2, and Fig. 4 is the enlarged view of the gearshift of Fig. 2.Selector fork 6 is fixed on the middle part of the axial direction of gearshift chosen axis 3.This selector fork 6 has and is fixed on the base portion 7 of gearshift chosen axis 3 and at the arm 8 that upwards stretches out from base portion 7 of footpath of gearshift chosen axis 3.In addition,, in a side of gearshift chosen axis 3, near selector fork 6, for example, three gearshift shifting blocks 9 are set.Therefore,, when gearshift chosen axis 3 moves and rotates around this axis on axial direction, the arm 8 of selector fork 6 will be optionally and the interlock of one of gearshift shifting block 9.Shifting fork is for example attached to gearshift shifting block 9 via this not shown gear shift fork shaft, and carries out speed change by the sleeve pipe that utilizes this shifting fork to move synchromesh mechanism.
Fig. 5 is the planimetric map of the selector fork of Fig. 4, and Fig. 6 is the left view of the selector fork of Fig. 4, and Fig. 7 is the rear view of the selector fork of Fig. 4.Because guide finge 12 is static, thus the steering channel 13 that gearshift chosen axis 3 can only insert along guide finge 12 move, therefore according to the movement of gearshift mode tuning gearshift chosen axis 3.
Note, steering channel 13 is arranged on the face of a side contrary with arm 8 of steering channel member 14 fixing on the base portion 7 of selector fork 6.Anti-reverse misoperation arm 15 is formed into this steering channel member 14, to the right-hand of steering channel 13 of Fig. 7, stretches out.This anti-reverse misoperation arm 15 directly moves to the 5th gear position for the chosen axis 3 that contacts to prevent from shifting gears of the anti-reverse error operation mechanism 16 by with Fig. 3 from reversing (moving backward) position.
Except steering channel member 14, cam member 17 is also fixed to the base portion 7 of selector fork 6.This cam member 17 is under the state of base portion 7 that is fixed on selector fork 6, and the vertical side of arm 8 in the planimetric map with Fig. 5 protrudes upward, and cam 18 is formed on the point stretching out.The cam face of this cam 18 forms the point stretching out of cam member 17, that is, the point that the side vertical with arm 8 in the planimetric map of Fig. 5 protrudes upward, and the moving body shown in Fig. 3 19 contacts with cam face as cam follower.This moving body 19 remains in the moving body retaining member 20 that is fixed on gearbox case 1, and elastomer 21(is shown in Fig. 8) be arranged on moving body retaining member 20 inside, make by this elastomer 21, moving body 19 to be squeezed in the cam face of cam 18.
For example, the neutral gear position that this cam face is set as the middle part on the above-below direction of Fig. 6 to shift gears on the axial direction of chosen axis 3, and by the middle part on the left and right directions of Fig. 6 be set as shifting gears chosen axis 3 around the neutral gear position in the sense of rotation of axis.These neutral gear positions pass through the steering channel 13 of Fig. 7 corresponding to the neutral gear position of gearshift pattern.In addition, as clear illustrating in Fig. 7, this cam face has: the upper domatic region 22 of axial direction, in this region, neutral gear position from the axial direction of gearshift chosen axis 3 is toward each in two of cam face reverse axial direction ends, larger to the distance of the axis of gearshift chosen axis 3; Domatic region 23 in sense of rotation, in this region, the neutral gear position the sense of rotation of gearshift chosen axis 3 is toward each in two of cam face reverse sense of rotation ends, larger to the distance of the axis of gearshift chosen axis 3; And sense of rotation Caused by Sloping Surfaces region 24, in this region and sense of rotation, domatic region 23 is continuous, and in this region, from with sense of rotation each in the reverse sense of rotation end of two of the cam face mentioned more forward of the border in domatic region, less to the distance of the axis of gearshift chosen axis 3.Note, on axial direction, in domatic region 22 and sense of rotation, domatic region 23 consists of essentially identical surface.Be also noted that, on axial direction in domatic region 22 and sense of rotation centered by the neutral gear position of domatic region 23 on axial direction and the neutral gear position in sense of rotation and be arranged on around it, and sense of rotation Caused by Sloping Surfaces region 24 be arranged on gearshift chosen axis 3 around the outside in the sense of rotation of axis, with domatic region 23 adjacency in sense of rotation.
In addition, described steering channel 13 has retainer 25, in retainer 25, guide finge 12 each gearshift direction on, that is, and gearshift chosen axis 3 in the sense of rotation of axis, contact with end.Be configured in the present embodiment, along with the movement on axial direction of gearshift chosen axis 3 with around the rotation of axis, while contacting with retainer 25 in the direction of respectively shifting gears of guide finge 12 at steering channel 13, be assembled to one of the moving body 19 of gearbox case 1 and sense of rotation Caused by Sloping Surfaces region 24 of the cam face of cam 18 and contact.Note, as shown in Figure 5, in the present embodiment, the maximum radius R1 of cam face is set to the maximum radius R2 that is greater than steering channel 13.
Fig. 8 illustrates the state of the neutral gear position of gearshift chosen axis 3 in the sense of rotation around axis.In this state, the moving body 19 being promoted by elastomer 21 on the axial direction of gearshift chosen axis 3 is positioned at the recess in the middle of domatic region 23 in adjacent sense of rotation,, neutral gear position, and the repulsive force that gearshift chosen axis 3 offers moving body 19 by elastomer 21 remains on this neutral gear position.On the contrary, as shown in Figure 9, when gearshift chosen axis 3 rotates in the counter clockwise direction shown in the figure around this axis, the moving body 19 being promoted by elastomer 21 on the axial direction of gearshift chosen axis 3 will move on one of domatic region 23 in sense of rotation.In this, the repulsive force of moving body 19 antagonism elastomers 21 elastomer 21 that gradually reduces, makes operational load become gradually large.When gearshift chosen axis 3 further rotates around this axis in the counterclockwise direction, moving body 19 will move to one of sense of rotation Caused by Sloping Surfaces region 24 in one of domatic region 23 sense of rotation.In this, sense of rotation Caused by Sloping Surfaces region 24 will offer the sense of rotation tip side of the repulsive force quick rotation of moving body 19 to cam face by elastomer 21.As mentioned above, when moving body 19 contacts with one of sense of rotation Caused by Sloping Surfaces region 24, guide finge 12 contacts the gearshift direction shift position place at steering channel 13 with retainer 25, while making when one of sense of rotation Caused by Sloping Surfaces region 24 or the chosen axis 3 of shifting gears the equally repulsive force quick rotation by moving body 19 to the sense of rotation end of cam face, guide finge 12 will contact with specifying the retainer 25 of each gearshift direction shift position of steering channel 13, and gearshift chosen axis 3 will remain on this shift position.This is similar clockwise rotate gearshift chosen axis 3 around this axis in the situation that.On the other hand, domatic region 23 period of contact in moving body 19 and sense of rotation, when for rotating the operational load of gearshift chosen axis 3 while diminishing, gearshift chosen axis 3 by fast return to neutral gear position.
The effect of described above while being gearshift the rotating around axis of chosen axis 3 (, during gear shift operation), but while moving on the axial direction of gearshift chosen axis 3, (, when selecting to operate) also produces similar effect.For example, while using Fig. 7 to selection operation, describe, the moving body 19 being promoted by elastomer 21 on the axial direction of gearshift chosen axis 3 is positioned at the recess in the middle of domatic region 22 on adjacent axial direction,, neutral gear position place, and the repulsive force that gearshift chosen axis 3 offers moving body 19 by elastomer 21 remains on this neutral gear position place.From this state, when gearshift chosen axis 3 moves on axial direction, the moving body 19 being promoted by elastomer 21 on the axial direction of gearshift chosen axis 3 will move on one of domatic region 22 on axial direction.In this, the repulsive force compresses elastomeric 21 that moving body 19 will antagonism elastomer 21, the operational load of the chosen axis 3 that makes to shift gears becomes large gradually.On the other hand, one of domatic region 22 period of contact on moving body 19 and axial direction, when for the chosen axis 3 that makes to shift gears, on axial direction, mobile operational load is removed, gearshift chosen axis 3 by fast return to neutral gear position.
Note, in the present embodiment, the maximum radius R1 of the cam face of described cam 18 is set to the maximum radius R2 that is greater than steering channel 13.Therefore, can be with respect to the rotation angle around axis of gearshift chosen axis 3, make the girth of cam face longer, thereby for example by more critically setting the pattern in domatic region 23 and sense of rotation Caused by Sloping Surfaces region 24 in sense of rotation, the operational load of (, during gear shift operation) in the time of can setting in more detail gearshift chosen axis 3 and rotate.
As mentioned above, in the gearshift of the manual transmission of present embodiment, the cam face that applies the cam 18 of operational load to gearshift chosen axis 3 when the cam face of moving body 19 extruding cams 18 has domatic region 22 on axial direction, in this region, neutral gear position from the axial direction of gearshift chosen axis 3 is toward each in two of this cam face reverse axial direction ends, larger to the distance of the axis of gearshift chosen axis 3.Therefore, in the situation that gearshift chosen axis 3 moves along this axis from this neutral gear position to another position, the elastomer 21 that moving body 19 is expressed to this cam face is compressed to the distance in domatic region 22 axial direction of this cam face according to the axis from gearshift chosen axis 3, and on axial direction, gearshift chosen axis 3 is applied to operational load.In addition, on axial direction, domatic region 22 is concave, and wherein neutral gear position is recess, and the repulsive force of the chosen axis 3 that makes to shift gears by elastomer 21 turns back to axial direction neutral gear position.On the other hand, the cam face that applies the cam 18 of operational load to gearshift chosen axis 3 when the cam face of moving body 19 extruding cams 18 also has: domatic region 23 in sense of rotation, in this region, neutral gear position the sense of rotation of gearshift chosen axis 3 is toward each in two of this cam face reverse sense of rotation ends, larger to the distance of the axis of gearshift chosen axis 3; And sense of rotation Caused by Sloping Surfaces region 24, in this region and sense of rotation, domatic region 23 is continuous, and in this region, from sense of rotation the border in domatic region toward each in two of cam face reverse sense of rotation ends, less to the distance of the axis of gearshift chosen axis 3.Therefore, at gearshift chosen axis 3 in the situation that moving body 19 with in scope that in sense of rotation, one of domatic region 23 contacts from this neutral gear position around this axis rotation, the elastomer 21 that moving body 19 is expressed to this cam face is compressed to the distance in domatic region 23 sense of rotation of cam face according to the axis from gearshift chosen axis 3, and the operational load in this sense of rotation is applied to gearshift chosen axis 3.In addition, in sense of rotation, domatic region 23 is concave, and wherein neutral gear position is recess, and the repulsive force of the chosen axis 3 that makes to shift gears by elastomer 21 turns back to sense of rotation neutral gear position.In addition, in the situation that gearshift chosen axis 3 turns to around this axis the position that moving body 19 contacts with one of sense of rotation Caused by Sloping Surfaces region 24, can be by repulsive force quick rotation in the downward direction in sense of rotation Caused by Sloping Surfaces region 24 of the elastomer 21 that applied by sense of rotation Caused by Sloping Surfaces region 24 chosen axis 3 of shifting gears.Therefore,, when the set positions above in the downward direction in sense of rotation Caused by Sloping Surfaces region 24 is shift position, can will shift gears chosen axis 3 quick rotation to this shift position by the repulsive force of the elastomer 21 that applied by sense of rotation Caused by Sloping Surfaces region 24.In addition, on axial direction in domatic region 22, sense of rotation domatic region 23 and sense of rotation Caused by Sloping Surfaces region 24 each can both free setting to the distance of the axis of gearshift chosen axis 3, thereby axial direction that can free setting gearshift chosen axis 3 and the operational load in sense of rotation.Therefore, can by single cam face apply simultaneously gearshift chosen axis 3 axial direction on operational load and the operational load in sense of rotation, and can freely set these operational loads, thereby can combine the chosen axis 3 that makes to shift gears in axial direction and sense of rotation, turn back to neutral gear position.
In addition, guide finge 12 in being inserted into steering channel 13 is along gearshift during motion of defect modes, under the state that guide finge 12 contacts one of sense of rotation Caused by Sloping Surfaces region 24 at moving body 19 and cam face, the end of corresponding steering channel 13 around the sense of rotation end of axis with gearshift chosen axis 3, contacts with retainer 25.Therefore, when the end of steering channel, that is, the position of retainer, while being set to shift position, can remain on this shift position place by gearshift chosen axis 3.
In addition, by the maximum radius R1 of this cam face being set as being greater than the maximum radius R2 of steering channel, can make the girth of cam face longer with respect to the rotation angle of gearshift chosen axis 3, thereby can set in more detail the operational load that is applied to gearshift chosen axis 3.
The application requires the preference of No. 2012-172810, the Japanese patent application submitted on August 3rd, 2012, and the full content of this application comprises in this application by reference.
