A kind of pair of speed transmission of clutch two
The present invention relates to automotive transmission technology, the more particularly to a kind of pair speed transmission of clutch two.
The driving cycle of automobile is complicated and changeable, and running resistance and travel speed change greatly, using the single-stage of only one of which speed reducing ratio
The electric automobile of reduction gear-box is often attended to one thing and lose sight of another, and to be obtained sufficiently large driving force and be overcome anxious acceleration, climb very steep slopes
Running resistance is accomplished by matching larger reduction gearbox, but this can not obtain higher because the rotating speed of motor is limited
Speed.Some high performance electric vehicles meet electric automobile pair using high pulling torque, high-power, high-revolving high performance motor
The dual requirementses of driving force and speed, but high-power high performance motor and its control system increase cost burden.If electronic
Automobile has multiple gears and according to the power demand gear selecting of automobile, can not only lift the power performance of electric automobile, moreover it is possible to drop
It is low to motor, electric machine control system, power battery pack requirement, so as to reduce power system of electric automobile cost.
Although many gear automotive transmissions matched with the heat engine such as gasoline engine, diesel engine technology maturation and have been widely used,
But it has the defects such as complex structure, volume are big, power transmission loss is big, manufacturing cost is high.Motor is than gasoline engine, diesel oil
The heat engines such as machine have wider range of rotating speed interval and torque characteristics, therefore there is no need to be equipped with the also big automobile of more expensive power transmission loss
Speed changer, electric automobile also needs to a kind of compact conformation, transmission efficiency, shift quality speed changer high.
The content of the invention
Have that two gears, shift quality are high, transmission efficiency it is an object of the invention to provide one kind, it is adaptable to electric automobile
The speed transmission of double clutches two.
To achieve the above object, the technical scheme taken of the present invention is：A kind of pair of speed transmission of clutch two is provided, including：The
One clutch, second clutch, gear pair, wherein, the described pair of speed transmission of clutch two also includes input shaft, output shaft,
Input shaft engages transmission motion and moment of torsion with output shaft by gear, and output shaft couples with first clutch, input shaft and second
Clutch couple, the first input shaft gear couples with input shaft, the first output shaft gear is enclosed within output shaft and with the first clutch
Device couples, and the second input shaft gear is enclosed within input shaft and couples with second clutch, the second output shaft gear and output shaft join
In some embodiments, the speed transmission of double clutches two also includes differential mechanism, and output shaft is engaged with differential mechanism by gear
Transmission motion and moment of torsion.
By the description of preceding solution, it is understood that the speed transmission of double clutches two of present invention offer because using above-mentioned side
Case, can obtain following beneficial effect：
Two speed reducing ratio are obtained, the driving force and velocity interval of motor is extended；
Simple structure, amount of parts is few；
Gearshift procedure quick and stable.

To make technical problem solved by the invention, technical scheme and beneficial effect become more apparent, below in conjunction with accompanying drawing and
Preferred embodiment, is described in further detail to the present invention.It should be appreciated that specific embodiments described below is only
Be used to illustrate, explain the present invention, it is substantially only exemplary, rather than be intended for limitation disclosure of the invention, should
With or purposes.
As shown in figure 1, the speed transmission 01 of double clutches two according to one of the preferred embodiment of the present invention, including：First clutch
Device 21, second clutch 22, gear pair (31 and 41,32 and 42), wherein, the described pair of speed transmission 01 of clutch two
Also include input shaft 10, output shaft 11, input shaft 10 engages transmission motion and moment of torsion with output shaft 11 by gear, defeated
Shaft 11 couples with first clutch 21, input shaft 10 couples with second clutch 22, the first input shaft gear 31 with
Input shaft 10 couples, the first output shaft gear 41 is enclosed within output shaft 11 and couples with first clutch 21, the second input
The geared sleeve of axle 32 couples on input shaft 10 and with second clutch 22, the second output shaft gear 42 and output shaft 11
Wherein, the described pair of speed transmission 01 of clutch two also includes differential mechanism 50, and output shaft 11 passes through defeated with differential mechanism 50
Go out gear 51 and the engagement transmission motion of differential gear 52 and moment of torsion.
To more fully understand the speed transmission 01 of double clutches two according to one of the preferred embodiment of the present invention, below to the embodiment
In each shelves power transmission line of double speed transmissions of clutch two be described in detail：
First grade of power transmission line：
The closure transmission motion of first clutch 21 and moment of torsion, second clutch 22 disconnect.
