Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the skill to each exemplary embodiment provided by the present invention
Art scheme is clearly and completely described.In the case of not conflicting, the feature in following embodiment and embodiment can phase
Combination mutually.
Refer to Fig. 1, for the arrangement of clutch of one embodiment of the invention.The power set that described arrangement of clutch is suitable for include
But it is not limited to vehicle, boats and ships etc..Arrangement of clutch 1 is connected to power source output shaft 40 and the output of gear teeth wheels as individual components
Between axle 50, for receiving power from power source output shaft 40, and by gear teeth wheels output shaft 50 and and change-speed gearing
The differential mechanism output power that group output shaft 50 connects is to drive load, and described load includes but not limited to such as automotive wheel etc..
Described arrangement of clutch 1 include a planetary body 10, controlling organization, first clutch 20a, second clutch 20b and
Gear teeth wheels 30.
Gear teeth wheels 30 have the first power shaft 30a and the second power shaft 30b and the first output shaft 30c and second defeated
Shaft 30d, and include first group of gear teeth wheels 30e for hanging odd number gear (such as 1,3,5 gear) and be used for hanging even number
Second group of gear teeth wheels 30f of gear (such as 2,4,6 gear).Wherein, the first power shaft 30a and the second power shaft 30b can be considered
The power shaft of gear teeth wheels 30, the first output shaft 30c and the second output shaft 30d can be considered the output shaft of gear teeth wheels 30,
Or in other words, the first output shaft 30c and the second output shaft 30d can be considered gear teeth wheels output shaft 50.Preferably, second is defeated
Entering axle 30b is hollow axle, and the first power shaft 30a is arranged in as in the second power shaft 30b of hollow axle.
First clutch 20a is connected between planetary body 10 and the first power shaft 30a.Second clutch 20b is even
It is connected between planetary body 10 and the second power shaft 30b.In the present embodiment, first clutch 20a and second clutch
The type of 20b, size can identical can also differ, and described type includes but not limited to traditional dry clutch and wet type
Clutch.First clutch 20a and second clutch 20b and gear teeth wheels 30 can be integrated in DCT (Dual Clutch
Transmission, double-clutch speed changer).
Planetary body 10 is connected between the power shaft of power source output shaft 40 and gear teeth wheels 30.Control machine
Structure is connected with the element in planetary body 10, for being controlled the element in planetary body 10 so that power
The power of source output shaft 40 output is successively via in planetary body 10, first clutch 20a and second clutch 20b
Individual, gear teeth wheels 30 are transferred to gear teeth wheels output shaft 50.
In the present embodiment, shown in Fig. 2, planetary body 10 is single planetary body.This list planetary motion
Mechanism 10 includes sun gear 11, be arranged at around sun gear 11 and with the planetary gearsets 12 of sun gear 11 external toothing and planet
The gear ring 13 of gear train 12 internal messing and the planet carrier 14 being arranged in planetary gearsets 12.Wherein, gear ring 13 is connected to move
Power source output shaft 40, can be considered that the power shaft with arrangement of clutch 1 is connected, to receive the power from power source output shaft 40 output.
Planet carrier 14 can be considered the output shaft of planetary body 10, is connected to the first power shaft 30a and second of gear teeth wheels 30
Power shaft 30b such that it is able to the power received from power source output shaft 40 is transferred to the first power shaft of gear teeth wheels 30
30a or the second power shaft 30b.
Controlling organization includes the first clutch being made up of driving link 15 and driven member 16, and by brake component 17 and quilt
The second clutch that brake component 18 is constituted.Driving link 15 is arranged at the inner side of gear ring 13, and driven member 16 is arranged at planet carrier 14
Above and being coaxially disposed with planet carrier 14, braked part 18 is arranged on sun gear 11 and coaxially fixes with sun gear 11.Wherein,
One clutch and the second clutch can include but not limited to friction plate clutch (also known as friction disk type brake), electricity
