It is arranged in than the input gear of the first stud gear transmission of gear and the input gear of second stud gear transmission
On jackshaft, two speed than gear first stud gear transmissions output gear and second stud gear transmission it is defeated
Go out gear and be arranged in three speed than on the input link of epicyclic transmission.
3. compare speed changer according to 12 speed any in claim 1 to 2, which is characterized in that the first shifting device packet
Contain and input shaft（Or jackshaft）First shifting connecting shaft part of connection, the input gear with advance input gear transmission（Or
Output gear）The advance input gear pair shifting part of connection, the input gear with retreating input gear transmission（Or output gear
Wheel）The retrogressing input gear pair shifting part of connection, the connecting shaft part of the first shifting device can be selected with advance input gear pair to be changed
Block piece retreats input gear pair shifting part connection transmission torque, and the second shifting device includes defeated with preposition planetary gear set
Enter component（Or jackshaft）Second shifting connecting shaft part of connection and two speed are than the first stud gear transmissions of gear
Output gear（Or input gear）The first stud gear transmission shifting part of connection becomes with second of two speed than gear
The output gear of fast gear driving pair（Or input gear）The second stud gear transmission shifting part of connection, the second shifting
The connecting shaft part of device can be coupled biography with first stud gear transmission shifting part or second stud gear transmission shifting part
Torque delivery, third shifting device include the third shifting driving link being connect with preposition planetary gear set input link, with before
The third shifting driven member for putting the sun gear connection of planetary gear set, the third shifting fastener being connect with rack, third
Shifting driven member can be coupled with third shifting driving link or third shifting fastener transmits torque, the 4th shifting device
It is connect comprising the 4th shifting driving link being connect with preposition planetary gear set input link, with the gear ring of preposition planetary gear set
The 4th shifting driven member, the 4th shifting fastener that is connect with rack, the 4th shifting driven member can change with the 4th choosing
It keeps off driving link or the 4th shifting fastener is coupled transmission torque, the 5th shifting device includes the row with postposition planetary gear set
5th shifting driven member of carrier connection, the 5th shifting driving link being connect with the sun gear of postposition planetary gear set, the
Five shifting driven members, which can be coupled to transmit torque or disconnect being coupled with the 5th shifting driving link, does not transmit torque.
4. compare speed changer according to 12 speed any in claims 1 to 3, which is characterized in that the first shifting device
Connecting shaft part can neither be coupled with advance input gear pair shifting part nor be coupled with retreating input gear pair shifting part, second
The connecting shaft part of shifting device can neither be coupled with first stud gear transmission shifting part nor be passed with second stud gear
Dynamic pair shifting part is coupled, third shifting driven member can neither be coupled with third shifting driving link and also with third shifting
Fastener be coupled, the 4th shifting driven member can neither be coupled with the 4th shifting driving link and also with the 4th shifting fastener
It is coupled, the 5th shifting driven member can neither be coupled with the 5th shifting driving link nor be coupled with the 5th shifting fastener.
5. compare speed changer according to 12 speed any in Claims 1-4, which is characterized in that part or all of gear pair
It can or V belt translation pair replacement secondary by chain drive.
