Left rim gear wheel, left front power transmission axle shaft gear arrive left outside freewheel clutch, left inside freewheel clutch respectively --- and it is left outside Compression spring, left inside compression spring --- left gas ejector sleeve --- left cylinder（Left cylinder piston, left cylinder body）；

D, the structure of right freewheel clutch, function are identical with left freewheel clutch, are symmetrical set.

3rd, the torsion distribution according to need operation principle of the super transfer gear：

3.1st, set using the total power transmission moment of torsion of 6*6 automobiles as M values；Automatically the combination of distribution three differential mechanism has three groups of parallel connection differentials to torsion Device receives torsion, and when each wheel is identical to traction, the torsion that each differential mechanism receives is M/3 values, and this is central differential Device have naturally M/3 values be assigned in, rear wheel；

Left and right differential mechanism distribution torsion be M/3+ M/3=2M/3 values, due to center differential axle shaft gear be named as a left side, Right double sided gear, and they have 1/2 active force on left and right differential mechanism, instead of axle shaft gear, therefore have left M/6 values to be transported to Front left wheel, right M/6 values are transported to right front wheel；Remaining, left M/6 values conveyer belt is left, rear wheel, right M/6 values belt right In, rear 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 same On individual housing, 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, In i.e., the driving force of rear wheel be M values；If during six wheel driving force differences, in parallel three differential mechanisms adjust mutually torsion Power is distributed, and total torque M values are always implemented among one in three differential mechanisms of parallel connection；

3.2nd, for 4*4 automobiles, 4 wheels each wheel demand torsion when road conditions are identical is identical, that is, has M/2 values Left and right differential mechanism is assigned to, at this moment the torsion of center differential is zero；If rear wheel demand is more than the torsion of front vehicle wheel, Supplemented by center differential；

3.3rd, 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 The torsion of front-wheel is M/4 values, and left and right differential mechanism separately has M/4 values to be assigned to other wheels, that is, left and right differential mechanism point respectively Torsion M/2 values are not received, and it is M/2 values to extrapolate center differential and undertake torsion；In each wheel demand difference torsion, by three Individual differential mechanism intermodulation in parallel.

4th, with reference to shown in Fig. 5, 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-left double sided gear the n of Δ n ' --- cylindrical planetary gear ---₄=n+ Δs n-Δ n ' --- left lateral star-wheel --- left front power transmission Axle shaft gear n₁=n-Δ n+ Δ n ', meets automobile guiding differential requirement.

5th, with reference to shown in Fig. 5, the operation principle of the sliding device of description control：

5.1st, left side：Left double sided gear often engages the internal layer tooth of left stepped gear, and rotating speed and torsion are controlled by right driving rear axle, Often engaged with left rim gear wheel, left anti-skidding axle shaft gear respectively in the outer layer tooth both sides of left stepped gear, their afterbodys are designed with unidirectionally Tooth is often engaged with respective freewheel clutch, 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 n₅ Speed difference by freewheel clutch control force rotating speed to reach normal, i.e. n_1≠2n、n_4≠0, wheel can not skid；

5.2nd, right side：The effect that control sliding device in right side controls sliding device with left side is identical；

5.3rd, in normal operation, left side n₄、n₂、n₁It is normal to be oriented to differential, turn n during great circle₄＜ n₅＜ n₁=n+ Δs n + Δ n ', turns 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, n₁ For without interfering movement, therefore normal turn differential is not influenceed.

6th, operation principle of the occlusion with 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：In left cylinder Left gas ejector sleeve is pulled outwardly by middle inflation, compresses left return spring, and left inside and outside freewheel clutch is pulled out by left slidiing pin, Its unidirectional tooth is set to depart from the unidirectional tooth of left rim gear wheel and left anti-skidding axle shaft gear in the left sliding device of compound control；Release right compound The sliding device of control 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 return in the presence of return spring, the freewheel clutch occlusion of arranged on left and right sides, make automobile turn into full-time full wheel, it is anti-skidding, The strong handling capacity automobile being normally oriented to.
