Other feature and advantage of the disclosure will the following detailed description will be given in the detailed implementation section.
Detailed description of the invention
Attached drawing is and to constitute part of specification for providing further understanding of the disclosure, with following tool
Body embodiment is used to explain the disclosure together, but does not constitute the limitation to the disclosure.In the accompanying drawings:
Fig. 1 is the structural schematic diagram according to the speed changer of an embodiment of the present disclosure；
Fig. 2 is the schematic block diagram according to the power-driven system of an embodiment of the present disclosure.
Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
According to one aspect of the disclosure, as shown in Figure 1, providing a kind of speed changer, which includes 4 He of double clutch
Single coupled planetary gears.
Double clutch 4 has first end 41 and second end.Wherein, the second end includes first axle 42 and the second axis 43.
Single coupled planetary gears include the first movement parts S1, the second movement parts S2 and third movement parts S3, the 4th
Movement parts S4 and the 5th movement parts S5.Single coupled planetary gears are well known to those skilled in the art, and the disclosure is to this
It is not described in detail.In brief, single coupled planetary gears are made of two groups of mutually nested planetary gear mechanisms, directly
Sun gear of the gear ring of the lesser one group of planetary gear mechanism of diameter as one group of planetary gear mechanism being relatively large in diameter.
The first axle 42 of double clutch 4 is connected with the first movement parts S1, the second axis 43 of double clutch 4 and the second movement parts
S2 is connected.
In the disclosure, any one of double clutch 4 and single coupled planetary gears can be used as speed changer
Output end, input terminal of the another one as speed changer.In one embodiment, the first end 41 of double clutch 4 can be used as
The input terminal of speed changer, the first movement parts S1, the second movement parts S2, third movement parts S3, the movement of the 4th movement parts S4 and the 5th
Any one in part S5 can be used as the output end of speed changer.In another embodiment, the first movement parts S1, the second fortune
Any one in moving part S2, third movement parts S3, the 4th movement parts S4 and the 5th movement parts S5 can be used as the defeated of speed changer
Enter end, the first end 41 of double clutch 4 can be used as the output end of speed changer.
The first end 41 of double clutch 4 can be the shell of double clutch 4, and double clutch 4 further includes two driven discs, double
The first axle 42 of clutch 4 can be connected by key with one of driven disc, the second axis 43 of double clutch 4 can with it is another
A driven disc is connected by key.Generally, the shell of double clutch 4 and two driven discs, which can be, all disconnects, i.e. first end
41 disconnect with first axle 42 and the second axis 43.When needing to engage one of driven disc, can control shell with it is corresponding
Driven disc carries out engagement to synchronous rotary, i.e. first end 41 and one of first axle 42 and the second axis 43 is sequentially connected, to make
Obtaining the power that first end 41 transmits can be exported by one in first axle 42 and the second axis 43, or be made from first axle 42
It can be exported by first end 41 with the power transmitted in the second axis 43.
It should be appreciated that the specific engagement state of double clutch 4 is controlled the influence of strategy, for those skilled in the art
For, can according to actually required transmission mode adaptive settings control strategy, so as in first end 41 and two
It is switched between the various modes such as output shaft is all off and one of first end 41 and two output shafts are sequentially connected.
In order to make the more compact structure of speed changer, convenient for being arranged on vehicle, as shown in Figure 1, the first axle of double clutch 4
42 can be with empty set on the second axis 43.
In the disclosure, by the way that double clutch 4 and single coupled planetary gears to be dexterously combined together, so that
A kind of two-gear transmission that structure is simple and convenient to operate can be obtained.
In the disclosure, the gear switching of speed changer is realized by double clutch 4, and double clutch 4 can allow for
The disconnection process of the engaging process and another driven disc of one driven disc overlaps when shift switching, so that torque be avoided to transmit
Momentary interruption, guarantee shift process and vehicle operation ride comfort.The synchronizer more complicated compared to mechanical structure, it is double from
Clutch all has greater advantage either in terms of ride comfort or reliability.
For using the second movement parts S2 of single coupled planetary gears as the output end of speed changer, work as double clutch
4 first end 41 be connected with first axle 42 and with the second axis 43 disconnect when, from the first end 41 of double clutch 4 input power according to
It is secondary to be transferred to the second movement parts S2 by the first axle 42 and the first movement parts S1 of double clutch 4；When the first end of double clutch 4
41 with the second axis 43 when being connected and disconnecting with first axle 42, and the power inputted from the first end 41 of double clutch 4 successively passes through double
Second axis 43 of clutch 4 is transferred directly to the second movement parts S2.It can be seen that under above two state, in speed changer
Power transfer path is different, and transmission ratio is different, therefore can make gear there are two speed changer tools.
Optionally, speed changer can also include output gear 8, which is connected to the output end of speed changer.
Single coupled planetary gears include the small sun gear being radially sequentially arranged from inside to outside, asteroid frame, small
Gear ring (big sun gear), major planet frame, bull gear.Wherein, small sun gear, asteroid frame and small gear ring (big sun gear) composition one
Planetary gear mechanism is covered, small gear ring (big sun gear), major planet frame and bull gear form another set of planetary gear mechanism.First fortune
Moving part S1, the second movement parts S2, third movement parts S3, the 4th movement parts S4 and the 5th movement parts S5 can be respectively Sunny
Any one of wheel, asteroid frame, small gear ring (big sun gear), major planet frame, bull gear.
In the embodiment shown in figure 1, the first movement parts S1 is bull gear, and the second movement parts S2 is major planet frame, the
Three movement parts S3 are small gear ring (big sun gear), and the 4th movement parts S4 is asteroid frame, and the 5th movement parts S5 is small sun gear.Its
In, output end of the second movement parts S2 as speed changer.
According to another aspect of the present disclosure, a kind of power-driven system is provided, as shown in Fig. 2, the system include motor 2,
Speed changer and output section, the line shaft of motor 2 as described above are connected with the input terminal of the speed changer, and output section is used for
The power of speed changer output is transmitted to drive vehicle.
For example, output section may include transmission gear 9, it also may include transmission gear 9 and differential mechanism 11.Transmission gear 9
Not only it engaged with the output gear of speed changer 8, but also was engaged with the final gear 10 of differential mechanism 11.The function of differential mechanism 11 is to work as vehicle
Turning driving or on uneven road surface when driving, roll left and right wheels with different angular speed, to guarantee two sides wheel
Make PURE ROLLING between ground.Final gear 10 is provided on differential mechanism 11, final gear 10 can be for example arranged in
On the shell of differential mechanism 11.
According to the another further aspect of the disclosure, a kind of vehicle, including power-driven system as described above are provided.
