1506 positions change and reposition when, through rod member 2 1503 force rod member 1 reposition, due to rod member 1 with
Pawl 1505 is to be fixedly connected, then pawl 1505 is rotated, and it is helicoid contact, now pawl meeting to determine pawl 1508 due to pawl 1505
Have relative to pawl is determined along the displacement component in the axial direction of axle one, so as to realize the relative fortune of two pairs of tires by control operation bar
Dynamic, determine pawl and the pawl being installed on axle one determine the oppositely oriented of pawl and pawl with being installed on axle two, are installed on axle one
The helicoid for determining pawl and pawl be left-handed face, the determine pawl and the helicoid of pawl being installed on axle two are dextrorotation face.Work as operation
Bar is moved to the left, and only the pawl on axle two determines pawl generation displacement relatively；When action bars moves right, the only pawl on axle one
Pawl is determined relatively produces displacement.
As shown in figure 3, actively conjugating wheel assembly 1 includes nut 501, fixed wheel 1, protection spacer 506, back-moving spring
One 505, displacement wheel 1, pressure bearing 504, are from left to right sleeved on axle 1 successively, thus, in fixed wheel 1 and change
The variable V-groove 1 of a well width is formed between position wheel 1.
As shown in figure 4, driven displacement wheel assembly 1 includes nut 501, back-moving spring 2 703, displacement wheel 2 702, fixed wheel
2 701, from left to right it is sleeved on successively on semiaxis 1 successively, the effect so set is：Thus, in the He of fixed wheel 2 701
The variable V-groove 2 704 of a well width is formed between displacement wheel 2 702, V-groove 1 and V-groove 2 704 are set with jointly
It can change and change the belt of coiling diameter with the groove width of V-groove one, V-groove two.
As shown in Fig. 1, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, described pawl 1505 engage with determining the helicoid of pawl 1508 and with
The right side of pressure bearing 504 is mutually leaned on, and is determined pawl and is fixed on casing 14, when pawl 1505 is produced along axle one relative to pawl 1508 is determined
During axial movement, pawl 1505 is moved by the compressing displacement of pressure bearing 504 wheel 1, so as to change the groove of V-groove 1
Width, belt can be tensioned or relaxation, so as to change to the pressure of displacement wheel 2 702 on driven displacement wheel assembly 1, in this pressure
Under the elastic force effect of back-moving spring 2 703, displacement wheel 2 702 can move left and right the groove width change for realizing V-groove 2 704, enter
And force belt to change its coiling diameter；When belt is moved up along V-groove 1, belt coiling diameter becomes big when upward,
When belt is moved downward along V-groove 1, belt coiling diameter diminishes, and then changes gearratio.
Operation principle：
The rotating forward of output axle shaft：
The left end of semiaxis 1 be fixed with it is driven displacement wheel assembly 1, through suit thereon with actively conjugate wheel assembly 1
On belt, the power for actively conjugating wheel assembly 1 pass to it is driven displacement wheel assembly 1, then it is driven displacement wheel assembly 1
Rotate；Because the driven wheel assembly 1 that conjugates is to be fixedly connected with semiaxis 1, so when driven displacement wheel assembly 1 is rotated
Then semiaxis 1 can be rotated with its constant angular velocity；Further, gear 48 is further fixed in semiaxis 1, is set on casing 14
There are semiaxis 2 V, output axle shaft VII, duplicate gear 1 is fixed with semiaxis 2 V, output axle shaft VII is fixed with gear 5 10；Enter
The bull wheel engagement of one step, gear 48 and duplicate gear 1, the steamboat of duplicate gear 1 is engaged with gear 5 10, such semiaxis
One IV rotate defeated through gear 48, the bull wheel of duplicate gear 1, the steamboat of duplicate gear 1, the engagement drive of gear 5 10 successively
Go out semiaxis VII to rotate forward, similarly, transmission of the opposite side through above-mentioned power of casing 14 can make another output axle shaft and output half
Axle VII keeps synchronized rotation in the same direction.
The reversion of output axle shaft：
The left end of semiaxis 3 VI be fixed with it is driven displacement wheel assembly 2 13, through suit thereon with actively conjugate wheel assembly 24
On belt, the power for actively conjugating wheel assembly 24 pass to it is driven displacement wheel assembly 2 13, then it is driven displacement wheel assembly two
13 rotate；Because the driven wheel assembly 2 13 that conjugates is to be fixedly connected with semiaxis 3 VI, so when driven 2 13 turns of wheel assembly of displacement
Then semiaxis 3 VI can be rotated with its constant angular velocity when dynamic；Similarly, semiaxis 3 VI is rotated successively through gear 6 12, duplicate gear 1
Bull wheel, the steamboat of duplicate gear 1, gear 5 10 engagement drive output axle shaft VII rotate, the opposite side of casing 14 is through above-mentioned
The transmission of power can make another output axle shaft keep synchronized rotation in the same direction with output axle shaft VII.
Due to actively conjugating wheel assembly 1 and actively conjugating the rotation direction of wheel assembly 24 on the contrary, so when using actively
When displacement wheel assembly 1 and use actively conjugate the output power of wheel assembly 24, the rotation direction of output axle shaft VII is opposite；
So, when using the output power of wheel assembly 1 is actively conjugated, equipment straight ahead；When defeated using wheel assembly 24 is actively conjugated
When going out power, equipment straight line is retreated；Due to gearbox into symmetrical structure and output shaft be semiaxis form, it is therefore only each other during output
It is vertical, change the rotating speed of the both sides output axle shaft of casing 14, one rotating speed is more than another rotating speed, you can realize that equipment is turned to；
The output axle shaft of the side of casing 14 can also rotated forward, the output axle shaft of opposite side inverts to realize equipment pivot stud.
Embodiment 2：The present embodiment without machine gearbox, with the difference without machine gearbox involved in embodiment 1
Centered on illustrate.
As shown in Fig. 1, Fig. 8, it is also equipped with being set with gear 7 16 on axle 3 VIII and output shaft Ⅸ, axle 3 VIII on casing 14
With gear 8 17, gear 9 20 is set with output shaft Ⅸ, gear 8 17 is engaged with gear 9 20, is set in the tooth on axle 2 III
It is duplicate gear to take turns 33, and the bull wheel of gear 33 is engaged with gear 22, and the steamboat of gear 33 is engaged with gear 7 16, axle 3 VIII
On be provided with output clutch 19, gear 7 16 is fixedly connected with the driving wheel of output clutch 19, and both are entirely through bearing
It is sleeved on axle 3 VIII, the driven pulley of output clutch 19 is movably connected in by way of key is connected on axle 3 VIII, shift fork 18
It is sleeved on output clutch driven pulley, for stirring the combination of the driving wheel of output clutch 19 and driven pulley with separating, and then
Control shaft 3 VIII receives the power on axle 2 III.
When the driving wheel of output clutch 19 and follower are combined, the power of input shaft I is through gear 1, gear 22, double
Join gear 3-1 bull wheel, duplicate gear 3-1 steamboat, gear 7 16, output clutch 19, axle 3 VIII, gear 8 17, gear
9 20 pass to output shaft Ⅸ.
When the driving wheel of output clutch 19 and follower are separated, the power of input shaft I is through gear 1, gear 22, double
Connection gear 3-1 bull wheel, duplicate gear 3-1 steamboat passes to gear 7 16, due to gear 7 16 by bearing empty set in axle
On 3 VIII, output clutch 19 is in the state of separation, so, now gear 7 16 can only dally on axle 3 VIII, and power is not
Transmit backward again, then output shaft Ⅸ is static.This stepless gearbox for carrying out dual output not only realizes walking（Or turn to）
The electrodeless variable-speed formula output of axle, and ensure dragging load output shaft can constant speed type output, and drag the power of load
It is flexibly controllable whether to export.
