K1+K2))/(K3(1+K1)).Under the gear, the first brake B1 closure causes the first sun gear 13 to brake, therefore 2 gears point
Two power transmission lines：1. the tooth of 22 → the second planet carrier of the → the second planetary gear the 24 → the 3rd is inputted by the power of the second sun gear 23
Enclose the gear ring 11 of the clutch C3 of 31 → the third line, 32 → the third line of star-wheel carrier the 34 → the 3rd → first and carry out power output；2. by
The planetary gear 12 → the of 21 → the first planet carrier of the power of two sun gear 23 input 22 → the second gear ring of the → the second planetary gear 14 → the first
One gear ring 11 carries out power output, specific as shown in Figure 3.
(3) 3 gears：When first clutch C1 and the 3rd clutch C3 is closed, speed is than i1=((1+K1) (1+K2)+K3 (1+
K1+K2))/(K3(1+K1+K2)).Under the gear, three planet rows both participate in transmission, 3 three power transmission lines of gear point：
1. action edge is entered by the second sun gear 23 and inputs 22 → the second planet carrier of the → the second planetary gear the 24 → the 3rd, 31 → the third line of gear ring
The gear ring 11 of the clutch C3 of 32 → the third line of star-wheel carrier the 34 → the 3rd → first carries out power output；2. entered by the second sun gear 23
The gear ring 11 of 14 → the first planetary gear of action edge input the → the second planetary gear 22 → the second gear ring, 21 → the first planet carrier 12 → the first
Carry out power output；3. 13 → the first row of sun gear of action edge input → first clutch C1 → first is entered by the second sun gear 23
The gear ring 11 of star-wheel 12 → the first carries out power output, specific as shown in Figure 4.
(4) 4 gears：When second clutch C2 and the 3rd clutch C3 is closed, speed is than i1=(1+K3)/K3).In the gear
Under, second clutch C2 closure causes the second planet row 2 to participate in being driven as a revolution is overall, 4 gear power transmission lines：
Entirety is turned round by the second planet row 2 and enters action edge → the second 24 → the three 31 → the third line of gear ring star-wheel 32 → the of planet carrier of input
The gear ring 11 of the clutch C3 of three planet carrier the 34 → the 3rd → first carries out power output, it is specific as shown in Figure 5.
(5) 5 gears：It is direct high, speed compares i1=1 when first clutch C1 and second clutch C2 is closed.In the gear
Under, first clutch C1 and closure causes the first planet row 1 and the second planet row 2 formation one to return while second clutch C2
Turn overall and participate in transmission, 5 gear power transmission lines：Entirety is turned round by the first planet row 1 and the second planet row 2 and enters action edge input
→ the first gear ring 11 carries out power output, specific as shown in Figure 6.
(6) 6 gears：It is overgear, speed is than i1=K1/ (1+K1) when second clutch C2 and the first brake B1 is closed.
Under the gear, second clutch C2 closure causes the second planet row 2 to participate in being driven as a revolution is overall, the first braking
Device B1 closure causes the first sun gear 13 to brake, 6 gear power transmission lines：Entirety is turned round by the second planet row 2 and enters action edge
Input the gear ring 11 of 14 → the first planetary gear of the → the first planet carrier 12 → the first and carry out power output, it is specific as shown in Figure 7.
(7) R is kept off：When first clutch C1 and second brake B2 is closed, realization is reversed gear, and speed compares i1=-K1.In the shelves
Under position, second brake B2 closure causes the first planet carrier 14 and the second gear ring 21 to brake, R gear power transmission lines：Second
Sun gear 23 inputs → and the first clutch C1 → gear ring 11 of 13 → the first planetary gear of the first sun gear 12 → the first enters action edge is defeated
Go out, it is specific as shown in Figure 8.
In the present embodiment, the first brake B1 one end is connected with the first sun gear 13, the first brake B1 other end
It is connected with mission case 4；First planet carrier 14 is fixedly connected with rear overall one end with second brake B2 with the second gear ring 21
Connection, the second brake B2 other end is connected with mission case 4.Actually the first sun gear 13 passes through the first braking

Three gear rings 31 are fixedly connected, and the second sun gear 23 is fixedly connected with power input link, and hence it is also possible to have multiple equivalent in addition
Technical scheme, such as the second planet carrier 24 are connected by second clutch C2 with power input link, the 3rd gear ring 31 is by second
Clutch C2 is connected with the second sun gear 23, the 3rd gear ring 31 is connected, etc. by second clutch C2 with power input link.
When second clutch C2 is closed, these technical schemes, which can be realized, makes the technique effect of the overall revolution of the second planet row 2.
The concrete operations logic of the specific manipulation logical AND embodiment one of embodiment two is identical, corresponding speed than also identical,
And embodiment two is consistent with the power flow trend of embodiment one.
Embodiment three
As shown in Figure 10, it is with the difference of embodiment one：Second clutch C2 is connected to the second planet carrier 24 and
Between two gear rings 21, it is, the second planet carrier 24 is connected by second clutch C2 with the second gear ring 21, in addition, second from
Clutch C2 is arranged between the second planet row 2 and third planet row 3.It is same what deserves to be explained is, due to the second planet carrier 24 with
3rd gear ring 31 is fixedly connected, and the second gear ring 21 is fixedly connected with the first planet carrier 14, and hence it is also possible to have multiple equivalent in addition
Technical scheme, such as the second planet carrier 24 are connected by second clutch C2 with the first planet carrier 14, the 3rd gear ring 31 is by second
Clutch C2 is connected with the second gear ring 21, the 3rd gear ring 31 is connected, etc. by second clutch C2 with the first planet carrier 14.When
When second clutch C2 is closed, these technical schemes, which can be realized, makes the technique effect of the overall revolution of the second planet row 2.
The concrete operations logic of the specific manipulation logical AND embodiment one of embodiment three is identical, corresponding speed than also identical,
And embodiment three is consistent with the power flow trend of embodiment one.
In summary, the present invention uses three clutches and two brakes, reasonably connects three planet row combinations
Get up, six forward gears can be achieved and one reverses gear；In addition, the brake quantity in the present invention is less than the quantity of clutch, more
Few brake quantity can not only reduce the difficulty of the processing and manufacture of mission case 4, also help the lightweight of casing,
Make whole speed changer more compact；Moreover, under conditions of equal number of ratios is met, less brake quantity obviously can
The utilization rate of each brake is improved, so that whole speed changer is more compact；Again, will be favourable using more clutches
Annexation between planet row is broken in particular gears incision, makes the planet row of redundancy be not involved in transmission, is stirred so as to reduce band row
Oil loss, improves efficiency；More clutches are set, by increasing planet row or increasing more manipulate after not only contributing to
The mode of part carries out multi-speed expansion, and when implementing to concrete structure design, can also set these clutches progress nesting
Meter, so that whole speed changer structure is more compact.
It the above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, without departing from the technical principles of the invention, some improvement and replacement can also be made, these, which improve and replaced, also should
It is considered as protection scope of the present invention.
