Or, sun gear is locked by mechanism, and power is input into from gear ring, from planet carrier output；
Or, sun gear is locked by mechanism, and power is input into from planet carrier, from gear ring output.
Driving link is done in both combinations any in can also there is sun gear, gear ring, planet carrier three, and remaining one is done passively
Part exports the motion conditions of power；
Can certainly be two strands of power respectively from both inputs any in sun gear, external toothing and planet carrier three,
By being exported from remaining one after power coupling.
For the first epicyclic gearsets 3, the first power set 1 and the second power set 2 are to the first epicyclic gearsets 3
Input power, has two strands of power to be input into from the first gear ring 31 and the first sun gear 32 respectively, equally, the first power set 1 and
Two power set 2 have two strands of power respectively from the second gear ring 41 and the second sun gear 42 to the input power of the second epicyclic gearsets 4
Input, the synthesis by planetary mechanism to moving, that is, carry out double dynamical synthesis and accelerate, but when in reversing arrangement
In the presence of 7, if having the direction of one power with another strand of power direction in appearing in two strands of power of planetary mechanism conversely, row
Star transmission group then carries out double dynamical inverse composition and acts on and retarded motion, for example, when reversing arrangement 7 acts on the first planet machine
During a certain bar power transport path of structure 3, the first epicyclic gearsets 3 carry out double dynamical inverse composition effect and slow down, and the
Two epicyclic gearsets 4 carry out double dynamical synthesis in the same direction and accelerate, it is possible thereby to realize caterpillar side crawler belt
Accelerate to rotate, opposite side crawler belt carries out retarded motion, the crawler track speeds of both sides are different, there is speed difference, so as to complete crawler type
The differential steering of vehicle.
When the side of caterpillar carry out underdrive to stop when, then be capable of achieving caterpillar side added
Speed, opposite side stops operating, so that the trimming for completing caterpillar is turned to.
If, without output, another one is to make one of the wherein locking of the first power input device 1 and the second power input device 2
First epicyclic gearsets 3 and the second epicyclic gearsets 4 provide power, changed to the first epicyclic gearsets 3 by reversing arrangement 7 or
The power input direction of the second epicyclic gearsets 4, then now the rotating output of same gearratio is realized in caterpillar both sides,
That is with certain rotational speed, opposite side is rotated backward with identical rotating speed, realizes caterpillar for caterpillar side
Zero turn radius.

The power direction that is input into the first sun gear 32 described in 2 and second sun gear 42 conversely, the first epicyclic gearsets 3 carry out it is double
The inverse composition of power is acted on and output of slowing down, and the second epicyclic gearsets 4 carry out the double dynamical acceleration output with the effect that is combined to,
It is possible thereby to realize that the acceleration of caterpillar side crawler belt is rotated, opposite side crawler belt carries out retarded motion, the crawler belt speed of both sides
Degree is different, there is speed difference, so as to complete the differential steering of caterpillar.
When the first epicyclic gearsets 3 carry out underdrive to stop when, then be capable of achieving caterpillar side accelerated,
Opposite side stops operating, so that the trimming for completing caterpillar is turned to.
If making the first power input device 1 lock without output, the second power input device 2 is simultaneously the He of the first sun gear 32
Second sun gear 42 provides power, because reversing arrangement 7 is connected with the first sun gear gear ring 32, in the work of reversing arrangement 7
Under, the second power input device 2 is input into equal in magnitude in opposite direction moving to the first planetary mechanism 3 and the second planetary mechanism 4
Power, then now the rotating output of same gearratio is realized in caterpillar both sides, i.e. caterpillar has the second planet machine
The side of structure 4 is rotated backward with certain rotational speed, the side with the first planetary mechanism 3 with identical rotating speed, realizes carrying out
The zero turn radius of belt vehicle.
It should be noted that when reversing arrangement 7 is connected with the second sun gear gear ring 42, the transmitting procedure of motion with
Above-mentioned phase is returned, and the second epicyclic gearsets 4 carry out double dynamical inverse composition effect and slow down and export, and the first epicyclic gearsets 3 are entered
Row is double dynamical to accelerate output with effect is combined to；First power input device 1 is locked during without output, and caterpillar has the
The side of one planetary mechanism 3 is reversely turned with certain rotational speed, the side with the second planetary mechanism 4 with identical rotating speed
It is dynamic, the zero turn radius of caterpillar are realized, here is omitted for specific transmitting procedure.
In the present embodiment, the reversing arrangement 7 is used to change incoming first gear ring 31 or second gear ring 41
