Brief description of the drawings
Fig. 1 the structural representation of present invention.
Embodiment
Shown in Fig. 1, be related to a kind of single speed automatic transmission of double pinions combined type four, including by front-seat planet carrier 6,
The front-seat single-stage planetary gear train that front-seat planetary gear 7, front-seat sun gear and front-seat gear ring are formed, and by heel row planet carrier
13rd, the first planetary gear of heel row 11, after ranked second planetary gear 10, the heel row twin-stage row that heel row sun gear and rear ring gear are formed
Star gear mechanism；Wherein, the front-seat sun gear and heel row sun gear close and shared front and rear row sun gear 8, the front row are made
Shared front and rear row gear ring 9 is made in gear ring and rear ring gear；
First output end of power input shaft 1 respectively with first clutch 2, the clutch 14 of second clutch 4 and the 3rd
Input connection, the output end of the first clutch 2 is connected with the front-seat planet carrier 6, the second clutch 4 it is defeated
Go out end to be connected with the front and rear row sun gear 8, the output end of the 3rd clutch 14 is connected with the heel row planet carrier 13；
The input of power output shaft 15 is connected with the front and rear row gear ring 9；
Wherein, it is provided between the first clutch 2 and the front-seat planet carrier 6 for the front-seat planet carrier 6
First brake 3 of braking；It is provided between the second clutch 4 and the front and rear row sun gear 8 for described front and rear
Arrange the second brake 5 that sun gear 8 is braked；Be provided between 3rd clutch 14 and the heel row planet carrier 13 for pair
The 3rd brake 12 that the heel row planet carrier 13 is braked.
The automatic transmission of the present invention is made up of two-row planetary gear mechanism, clutch, brake, front-seat planetary gear machine
Structure is single stage type, and heel row planetary gears is stage type, it is front-seat with the sun gear of heel row planetary gears and gear ring it is each
Parameter is identical, and its Rational Parameters configures the gear that can form 4 gearratio reasonable layouts, and power transmission during each gear work
Route is simple.
In use, assume that the front and rear row sun gear number of teeth is Z1, the front and rear row gear ring number of teeth is Z2, then α=Z can be made2/Z1.Below
For each gear power transmission line and gear ratio calculation.
1 gear：Second clutch 4, the 3rd brake 12 work.Power from power input shaft 1 is through second clutch 4 by front and rear
Row sun gear 8 input, through the first planetary gear of heel row 11, after ranked second planetary gear 10, front and rear row gear ring 9, power output shaft
15 output power.Calculated according to movement relation formula, 1 gear gearratio i1=α.
2 gears：Second brake 5, the 3rd clutch 14 work.Power from power input shaft 1 is through the 3rd clutch 14 after
Seniority among brothers and sisters carrier 13 is inputted, and planetary gear 10, front and rear row gear ring 9, power output shaft 15 are ranked second after and exports power.According to motion
Relational expression calculates, 2 gear gearratio i2=α/(α -1).
3 gears：First clutch 2, second clutch C24 work.Power from power input shaft 1 is simultaneously through first clutch 2
Be transmitted to front-seat planet carrier 6 and front and rear row sun gear 8 with second clutch 4, then premenstrual rows of planetary gear 7 be transmitted to front and rear row gear ring 9,
Power output shaft 15 exports power.Calculated according to movement relation formula, 3 gear gearratio i3=1.
4 gears：First clutch 2, second brake 5 work.Before power from power input shaft 1 is transmitted to through first clutch 2
Carrier 6 is ranked, then premenstrual rows of planetary gear 7 is transmitted to front and rear row gear ring 9, power output shaft 15 exports power.According to movement relation
Formula calculates, 4 gear gearratio i4=α/(1+ α).
Reverse gear [R gears]：First brake 3, second clutch 4 work.Power passes through power input shaft 1, second clutch 4
To front and rear row sun gear 8, then premenstrual rows of planetary gear 7 is transmitted to front and rear row gear ring 9, power output shaft 15 exports power.According to fortune
Dynamic relational expression calculates, back gear ratio iR=-α.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
