The speed ratio of this kind of drive mechanism calculates and the computational methods of power stream distribution are as follows:
From Gear Planet Transmission characteristic:
Z1*n1+Z3*n3=n2*(Z1+Z3) (1)
Driving of parallel axes characteristic understands:
Z5*n2= -Z6*n5 (2)
Z9*n4= -Z10*n3 (3)
If Z8/Z9=A, then n4=-A*n5 (4)
(4) are substituted into (3) obtain:
A*Z9*n5=Z10*n3 (5)
(5) and (2) are substituted into (1) obtain:
Μ is total=n1/n5=-((A*Z3*Z9)/(Z10*Z1)+(Z6* (Z1+Z3))/(Z5*Z1)) (6)
From computational methods and the moment of torsion partition characteristic of Gear Planet Transmission of power:
P2/P3=(n2*(Z1+Z3))/(n3*Z3) (7)
(2)/(5) can be obtained:
N2/n3=(Z6*Z10)/(A*Z5*Z9) (8)
(8) formula substitution (7) formula is obtained:
P2/P3=((Z1+Z3)/Z3) * (Z6*Z10/ (A*Z5*Z9)) (9)
If (Z1+Z3)/Z1=B (10)
Then: Z3=Z1* (B-1) (11)
By formula (10), (11) substitution (6) Shi Ke get:
Μ is total=-((A*(B-1) * (Z9/Z10))+(B*Z6/Z5)) (12)
Bring formula (11) into (9) formula to obtain:
P2/P3=(B/ ((B-1) * A)) * (Z6*Z10/ (Z5*Z9)) (13)
If P2/P3=C (14)
Formula (14) is substituted into formula (13) obtain:
Z6*Z10=(C*(B-1)*A/B)*(Z5*Z9) (15)
(12) formula is arranged:
Μ is total=-(A* (B-1) * Z5*Z9+B*Z6*Z10)/(Z5*Z10)
Formula (15) is substituted into:
Μ is total=-A* (1+C) * (B-1) * (Z9/Z10) (16)
By formula (13), mechanism can realize setting in closing branch road by obtaining each gear ratio in adjustment driving-chain
Fixed power than C, understands the overall ratio of mechanism by formula (16) and the power closed in branch road is more closely related than C, this with
The gear ratio calculation of traditional closed planetary has the difference of essence, and the speed ratio of closed planetary calculates and the most only has with gear ratio
Close, therefore The present invention gives a kind of brand-new closing differential speed ratio computational methods.

Adjustment, can arbitrarily allocate power.See Fig. 1, the power of 75% can be distributed to axle 7 by planet carrier 4, the wherein power of 50%
Directly being exported by the first gear shaft 8, the power of 25% flows on the second gear shaft 9, this Partial Power and the output of ring gear 3
To the power interflow of the 25% of the 3rd gear shaft 10, the power with 50% exports from the second gear shaft 9.First gear shaft 8 and second
Gear shaft 9 is the power output of 50%.Adjust the speed ratio of planetary mechanism, i.e. power on two output shafts of adjustable.
