Left and right differential mechanism distribution torsion is M/3+ M/3=2M/3 values, because center differential axle shaft gear is named as left and right pair Face gear, and they have 1/2 active force on left and right differential mechanism, instead of axle shaft gear, therefore there have left M/6 values to be transported to be left front Wheel, right M/6 values are transported to right front wheel；Remaining, left M/6 values conveyer belt is left, rear wheel, in right M/6 values belt right, after Wheel, i.e.,：

M/6+ M/6+ M/3=4M/6, so, Mei Gezhong, the driving torque of rear wheel are 4M/6 ÷ 4=M/6 values；

When each wheel torsion demand of 6*6 automobiles is not simultaneously as three groups of differential mechanisms are in parallel, their power taking point is in same shell On body, therefore there is the mutual conditioning function of torsion；If when two front vehicle wheels are without driving force, torsion is all undertaken by center differential, i.e., in, The driving force of rear wheel is M values；If during six wheel driving force differences, in parallel three differential mechanisms adjust mutually torsion point Match somebody with somebody, total torque M values are always implemented among one in three differential mechanisms of parallel connection；

2nd, for 4*4 automobiles, 4 wheels each wheel demand torsion when road conditions are identical is identical, that is, has M/2 values to be assigned to Left and right differential mechanism, at this moment the torsion of center differential is zero；If rear wheel demand is more than the torsion of front vehicle wheel, by center Differential mechanism supplements；

3rd, for 8*8 automobiles, it is respectively M/8 values that each wheel distributes moment of torsion under adhesive force the same terms, left and right two front-wheel Torsion is M/4 values, and left and right differential mechanism separately has M/4 values to be assigned to other wheels respectively, that is, left and right differential mechanism receives respectively To torsion M/2 values, it is M/2 values to extrapolate center differential and undertake torsion；In each wheel demand difference torsion, by three parallel connections Differential mechanism intermodulation.

With reference to shown in Fig. 7, differential motion operation principle is described：

If automobile turns left, then have：

n₃=n+ Δ n+ Δ n ',

n₂=n-Δ n-Δ n ',

n₁=n-Δ n+ Δ n ',

n₄=n+ Δs n-Δ n '；

Wherein, Δ n speed differences between wheel, Δ n ' is between centers speed difference；

And then power transmission axle shaft gear n before the right side₃=n+ Δ n+ Δs n ' --- right lateral star-wheel --- right double sided gear n₂=n-Δ n- The left double sided gear n of Δ n ' --- cylindrical planetary gear ---₄=n+ Δs n-Δ n ' --- left lateral star-wheel --- left front power transmission semiaxis Gear n₁=n-Δ n+ Δ n ', meets automobile guiding differential requirement.

With reference to shown in Fig. 7, the operation principle of the sliding device of description control：

1st, left side：Left double sided gear often engages the internal layer tooth of left stepped gear, by right driving rear axle control rotating speed and torsion, in Zuo Ta The outer layer tooth both sides of gear are often engaged with left rim gear wheel, left anti-skidding axle shaft gear respectively, their afterbodys be designed with unidirectional tooth with Respective freewheel clutch is often engaged, and the side of the left compound sliding device composite differential control wheel of control is skidded；

Such as n₁=0,、n₄During=2n, then n₂=0、n₃=2n, left side wheel rotating speed are 0, and right side wheels rotating speed is 2n；During skidding, by n₄= 2n forces n₆Drive n₁There are rotating speed, i.e. n_1≠0, then n_2≠0, wheel can not skid；

Such as n₁=2n、n₄When=0, then n₂=2n、n₃=0,2n=n is understood by differential mechanism property₁+n₂, obtain：

2n=2（2 n₂）；Make n₄/n₆=k（2 ＞ k ＞ 1）, 4n₂=n₄+n₅K, 4n₂=0+n₅K, n₅=4n₂/ k ＞ n₁=2n, n₁With n₅Speed Difference forces rotating speed to reach normal by freewheel clutch control, i.e. n_1≠2n、n_4≠0, wheel can not skid；

2nd, right side：The effect that control sliding device in right side controls sliding device with left side is identical；

3rd, in normal operation, left side n₄、n₂、n₁It is normal to be oriented to differential, turn n during great circle₄＜ n₅＜ n₁=n+ Δ n+ Δ n ', Turn n during ringlet₄＞ n₆＜ n₁=n-Δ n-Δ n ', in n₅＜ n₁、n₆＜ n₁When, left outside, internal overrunning coupler（Unidirectionally tooth is Zigzag）By left outside, interior compression spring left outside, the unidirectional tooth inclined-plane of internal overrunning coupler can be controlled to skid off, n₁For without dry Motion is related to, therefore does not influence normal turn differential.

With reference to shown in Fig. 6, occlusion and the operation principle for departing from the sliding device of control：

When reversing turns sharp turn, the sliding device work of left and right compound control is released；Release the process of the left sliding device of compound control：Filled in left cylinder Left gas ejector sleeve is pulled outwardly by gas, compresses left return spring, is pulled out left inside and outside freewheel clutch by left slidiing pin, is made it Unidirectional tooth departs from the unidirectional tooth of the left rim gear wheel and left anti-skidding axle shaft gear in the left sliding device of compound control；Right compound control is released to slide Device is identical with the left compound sliding device of control；So as to turn into full-time all-wheel drive vehicle transmission；

In automobile normal running and straight line car-backing, the gas in left cylinder, right cylinder is released, left gas ejector sleeve and right gas ejector sleeve The return in the presence of return spring, the freewheel clutch occlusion of arranged on left and right sides, automobile is turned into full-time and take turns entirely, be anti-skidding, normal The strong handling capacity automobile being oriented to.
