Parameter) transmission；One clutch is used to connect drive device and planet carrier, and the high gear gearratio realized during its engagement is 1
Transmission.And the generally optional scope of the structural characteristic parameter k of automobile-used planet row is 1.5~4.0, preferred scope is 1.8~3.5,
Therefore the attainable low gear gear range of two shift transmission is 2.5~5 or 2.8~4.5 so that kept out between high gear
Gear difference it is excessive, it is difficult to realize that power does not interrupt gearshift.
Utility model content
The purpose of this utility model is the shortcoming for overcoming above-mentioned prior art, there is provided one kind can realize high gear and low
Gear does not interrupt the automobile-used two gears speed-changing driving device of switching.
To achieve these goals, the utility model has following composition：
The automobile-used two gears variable speed drive system, it is mainly characterized by, described two gears variable speed drive systems include clutch,
Planet row and drive device, described drive device connect described planet row, described planet row by described clutch
Including passing sequentially through the intermeshing gear ring of tooth, the first planetary gear, the second planetary gear and the sun gear that match, described clutch
Device includes first clutch and second clutch, and described first clutch is connected to described drive device and described row
Between carrier, described second clutch is connected between described drive device and described gear ring, and described planet row is also
Wheel is connected with by gear ring.
It is preferred that described planet row is the planet row that a structural characteristic parameter scope is 1.8 to 3.5.
It is preferred that described planet row is the planet row that a structural characteristic parameter is 2.
More preferably, described drive device is a motor or an engine.
Using the automobile-used two gears variable speed drive system, because it uses two clutches, the gear ring of planet carrier is connected respectively
With drive device and planet carrier and drive device, and described gear ring drives described wheel, makes the transmission of described planet row
Than being engaged in first clutch, second clutch separate when be k/ (k-1), first clutch separate, second clutch engage when
Gearratio is 1, on the premise of between the structural characteristic parameter of the planet row is for 1.8 to 3.5, the biography of planet row in the case of two kinds
It is dynamic more little than changing, therefore when carrying out the switching of high gear, low gear, will not be realized as occurring fierce saltus step in the prior art
Power does not interrupt gearshift.

Specific embodiment
In order to more clearly describe technology contents of the present utility model, traveling one is entered with reference to specific embodiment
The description of step.
The automobile-used two gears variable speed drive system, it is mainly characterized by, described two gears variable speed drive systems include clutch,
Planet row 103 and drive device 201, described drive device 201 connect described planet row 103 by described clutch,
Described planet row 103 includes passing sequentially through the intermeshing gear ring 1031 of tooth, the first planetary gear 1034, the second row for matching
Star-wheel 1035 and sun gear 1032, described clutch include first clutch 1021 and second clutch 1022, and described
First clutch 1021 is connected between described drive device 201 and described planet carrier 1033, described second clutch
1022 are connected between described drive device 201 and described gear ring 1031, and described planet row 103 also passes through gear ring 1031
It is connected with wheel.
Described planet row 103 is the planet row 103 that a structural characteristic parameter scope is 1.8 to 3.5.
Described planet row 103 is the planet row 103 that a structural characteristic parameter is 2.
Described drive device 201 is a motor or an engine.
In a kind of specific embodiment, two gear variable speed drive systems 100 two gears of height can by control first from
The separation of clutch 1021 and second clutch 1022 and engagement are realized.When first clutch 1021 is engaged and second clutch
During 1022 separation, two described gear variable speed drive systems realize low gear, and now the gearratio of planet row 103 is k/ (k-1), its
In, k is the structural characteristic parameter of planet row 103；It is described when second clutch 1022 is engaged and first clutch 1021 is separated
Two gear variable speed drive systems realize high gear, and now the gearratio of planet row 103 is 1.
When sun gear 1032 is fixed, planet carrier 1033 is input into, and when gear ring 1031 is exported, can obtain corresponding low gear gearratio
iLEquation (2) is as follows：
nt-k*nq+(k-1)nj=0；
iL=nj/nq=k/ (k-1)；
Wherein, described nt、nqAnd njIt is respectively sun gear 1032, gear ring 1031 and the rotating speed of planet carrier 1033.Automobile-used planet
The optional scope of the structural characteristic parameter k of row is 1.5~4.0, and preferred scope is 1.8~3.5, and two shift transmissions 100 can be realized
Low gear gear range be 1.33~3, the low gear gear range of preferred implementation is 1.4~2.25.Wherein, preferred implementation
Low gear gear range 1.4~2.25 is the irrealizable low gear gearratio of prior art.When k selections 2, low gear gearratio is
2。
Because the attainable low gear gear range of two shift transmission 100 is 1.4~2.25, therefore, drive device 201 can
To be engine or motor, wherein, the relatively low low gear gearratio of numerical value can match engine and use, and numeric ratio is higher
Low gear gearratio can match motor and use.
Using the automobile-used two gears variable speed drive system, because it uses two clutches, the gear ring of planet carrier is connected respectively
With drive device and planet carrier and drive device, and described gear ring drives described wheel, makes the transmission of described planet row
Than being engaged in first clutch, second clutch separate when be k/ (k-1), first clutch separate, second clutch engage when
Gearratio is 1, on the premise of between the structural characteristic parameter of the planet row is for 1.8 to 3.5, the biography of planet row in the case of two kinds
It is dynamic more little than changing, therefore when carrying out the switching of high gear, low gear, will not be realized as occurring fierce saltus step in the prior art
Power does not interrupt gearshift.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still can be with
Various modification can be adapted and conversion is without departing from spirit and scope of the present utility model.Therefore, specification and drawings are considered as
