Description
Technical field
The utility model is related to auto parts and components mounting technique field, and in particular to a kind of peace of shifting block and shifting shaft
Assembling structure and a kind of gearbox.
Background technology
, it is necessary to which by control crank, gear is realized by shifting wire drawing, shifting shaft for manual gear gearbox
Switching, this be accomplished by ensure shifting wire drawing can closely be linked together with shifting shaft.As shown in Figures 1 to 5, generally
Shifting wire drawing is connected with switching mechanism, and the wherein switching mechanism includes shifting rocking arm 11, shifting support 13 and shifting
Block 14, shifting rocking arm 11 is connected with shifting support 13 by ball pin 12, shifting wire drawing and the outer end of shifting rocking arm 11
It is connected, the other end of shifting rocking arm 11 is connected with shifting block 14 by ball pin 12, passes through leverage, shifting wire drawing energy
It is enough that shifting block 14 is controlled, realize the axial movement and rotation of shifting block 14.In order to ensure that shifting shaft 15 can be with
On-demand shift block 14 is moved and rotated, it is necessary that the connection between shifting block 14 and shifting shaft 15 is led to be rigidly connected
Often intersect the gearshift axis hole 141 and pin hole 142 communicated provided with two on shifting block 14, be respectively for insertion into the He of shifting shaft 15
Bayonet lock 16, when bayonet lock 16 communicates place through holes, can just be stuck on the neck 151 of shifting shaft 15, then pass through nut 17
Or other locking mechanisms make bayonet lock clamping, you can realize being rigidly connected for shifting block 14 and shifting shaft 15.And in order to ensure
Shifting block 14 has commutativity, it is necessary to ensure that bayonet lock 16 easily can take apart from shifting block 14.
In the prior art, the epimere 161 of bayonet lock 16 is to have helicitic texture on cylinder, its whole face of cylinder, bayonet lock 16
The side of hypomere is the semicircular structure 162 being engaged with the pin hole 142 on shifting block 14, and its opposite side is and shifting shaft
The strip wedge structure 163 that neck 151 on 15 is engaged.Wherein, the top of strip wedge structure 163 is small end 164,
Bottom is big end 165, and the width of strip wedge structure 163 is less than the width of the neck 151 of shifting shaft 15.During assembling, it will change
Gear shaft 15 passes through the gearshift axis hole 141 of shifting block 14, the neck 151 of shifting shaft 15 is located in gearshift axis hole 141, and rotate
Adjustment direction, makes neck 151 face pin hole 142, now inserts bayonet lock 16 from the bottom of pin hole 142, the court of epimere 161
On, strip wedge structure 163 is stuck in the neck 151 of shifting shaft 15, now the top of epimere 161 from pin hole 142 is worn
Go out, pad 18, nut 17 are arranged on the epimere 161 successively, and nut 17 is screwed on epimere 161 with spanner, with epimere
161 coordinate with the screw thread of nut 17, and in the presence of screw-down torque, bayonet lock 16 is constantly up moved, strip wedge structure 163
Function to, its big end 165 will be moved up, and constantly compress shifting shaft 15, so as to realize shifting block 14 and shifting shaft
15 are rigidly connected.During dismounting, locking nut is backed out from epimere 161 with spanner, then with hammer or other instruments gently down
Bayonet lock 16 is struck, bayonet lock 16 can take out from the bottom of pin hole 142, so as to realize dismounting and change.
Driven type for two, speed change box back is directly connected with power transmission shaft, and now the space of the lower end of shifting block 14 is relative
It is larger, it is sufficient to bayonet lock 16 is taken out from the lower section of pin hole 142.However, for 4 wheel driven vehicle, speed change box back is wanted and transfer gear
It is connected, because transfer gear is relatively large, causes the space of the lower end of shifting block 14 smaller, so that the peace installation and dismantling of bayonet lock 16
Unload more difficult, installation operation can not be carried out by resulting even in.

It is to realize to connect by left hand thread engagement between rotation screwed hole 42 so that bayonet lock is not only moved down with locking nut 51,
Also moved down because of the cooperation of left hand thread, this causes the raising that the speed that bayonet lock is moved down has been obtained, now bayonet lock to
The speed of lower movement will be faster than the speed that locking nut 51 is moved down, so that the installation of bayonet lock is more quick；Continue to revolve
Turn locking nut 51, strip wedge structure 43 will gradually extrude shifting shaft 31 by neck, until shifting shaft 31 is locked
In shifting block 21, as shown in figure 12；When needing dismounting, carry out reverse operating, it is identical with aforementioned principles, it is left,
In the presence of right-handed thread structure, the speed that bayonet lock is moved up will be faster than the speed that locking nut 51 is moved up, until long
Bar shaped wedge structure 43 releases the compression to shifting shaft completely, when locking nut 51 is detached from pin hole 22, just can
Bayonet lock directly is taken out from pin hole 22 with hand, so that the dismounting of bayonet lock is more convenient, quick.
The shifting block and the mounting structure of shifting shaft provided from said process, the utility model embodiment, it blocks
Pin can be mounted and dismounted from the upper end of shifting block 21, so that the lower end for preferably solving shifting block 21 installs empty
Between it is smaller when, the problem of installation and removal of bayonet lock are more difficult；Meanwhile, it passes through the setting of left and right hand thread structure so that
The installation and removal of the bayonet lock are more quick, so as to greatly increase efficiency of the bayonet lock in installation and removal.
It should be noted that the speed that moves down of bayonet lock is bayonet lock relative to the speed that shifting block 21 is moved down,
The speed that locking nut 51 is moved down is locking nut 51 relative to the speed that shifting block 21 is moved down.Work as left hand thread
Pitch it is identical with the pitch of right-handed thread when, when carrying out aforementioned operation, under the speed that bayonet lock is moved down will be locking nut 51
2 times of the speed of shifting, the speed that bayonet lock is moved up will be 2 times of the speed that locking nut 51 is moved up, so as to greatly improve
Efficiency of the shifting block 21 with shifting shaft 31 in installation and removal.
Further, the axial length of axial left handed threaded hole 42 can be more than the axial length of hypomere 54, so as to
Effectively the length of fit between increase bayonet lock and the hypomere 54 of locking nut 51, improves the shifting block 21 and shifting shaft 31
The reliability of mounting structure.
