Gear shift track 134 has first side 139, second side 140 and intermediate point 141.
Gear shift track 137 is engaged to the intermediate point of gear shift track 129,131 and 133.This joint makes first end 142,143 and 144 of gear shift track 129,131 and 133 be positioned at respectively on first side 139, and second end 147,148 and 149 of gear shift track 129,131 and 133 is positioned at respectively on second side 140.
Gear shift track 127 is placed on first side 139, make first end 151 of gear shift track 127 be installed on first side 139, and second end 152 of gear shift track 127 is connected to an end 153 of gear shift track 134.Similarly, gear shift track 134 is placed on second side 140, make first end 157 of gear shift track 134 be connected to the other end 158 of gear shift track 134, and second end 160 of gear shift track 134 is disposed on second side 140.

Figure 21 show second speed changer second embodiment open view.Second embodiment uses planetary gear set or assembly to drive gear to carry out the 7th.
Planetary gear set comprises one or two axle.This axle is connected to other gear, and the independently actuation gear that this gear is transfused to axle 76 drives.Actuation gear can for example drive planetary gear set via driven the 3rd gear 103.
In order to realize the high speed ratio hypervelocity of the 7th gear ratios, planetary gear set is worked with output sense of rotation identical operations pattern with the input sense of rotation that keeps planetary gear set.
When the hollow gear of planetary gear set was maintained fixed, simple planetary gear set was the rotation faster of its sun gear with the movement conversion of its support body or planet carrier.Use driven the 3rd gear 103 to drive support body and have the advantage of saving assembling space, and can provide suitable pre-speed ratio for planet the 7th gear.
As embodiment's a example, driven the 3rd gear 103 is shown in Figure 21 to be the driver of planet the 7th gear.Planet the 7th gear comprises support body C, sun gear A and hollow gear B.Sun gear A is as output shaft.Hollow gear B is fixed to basis or case of transmission, and it causes the gear ratio change expected and the rotation mode of expectation.
In order to realize for example 0.5 hypervelocity speed ratio, needing the effective ratio (stand-ratio) of simple planetary is 2.2, supposes that the 3rd gear speed speed ratio is 1.6.Output sun gear A is connected to synchronizer S 100, and it can be shared with idle running reverse gear 99, to realize the hypervelocity gear shift pattern of Figure 10.In this case, synchronizer S refers to the bilateral coupling arrangement 100 of Figure 10.
For any transmission that is reduced under the low grade pulls, freewheel can be increased, and it is marked as overrunning clutch (OWC) in Figure 21.Yet, the configuration of this freewheel mean in the overdirve gear bit pattern engine braking and sliding mode is fuel-efficient may be no longer feasible.
Figure 22 shows second embodiment's the graphical diagram of second speed changer of Figure 21, and Figure 23 shows the torque path of hypervelocity gear velocity ratio of second speed changer of Figure 22.
Input shaft 76 receives input torque.This moment of torsion, transmits via the planetary gear set of Figure 21 with via bilateral coupling arrangement 100 via idle running the 3rd gear 103 then via fixing the 3rd gear 93.Bilateral coupling arrangement 100 is with the planetary pinion set of bond or be connected to planetary gear set.Moment of torsion is subsequently via last countershaft 78, via last small gear 80, and transmits via differential gear 85.
