Abstract

The invention discloses a three-clutch transmission device for an electric vehicle. The three-clutch transmission device is characterized by comprising an input shaft (1), a K1 clutch (2), a K2 clutch (3), a K3 clutch (4), a first-gear gear (5), a second-gear gear (6), a third-gear gear (7), an output shaft (10), a conduction device (11) and a gear controller, wherein the K1 clutch (2), the K2 clutch (3) and the K3 clutch (4) are respectively connected with the first-gear gear (5), the second-gear gear (6) and the third-gear gear (7); the gear controller automatically controls the output shaft (1) to be switched into different shifts through different clutches; and the output shaft (10) is connected with a gear-shifting gear through the conduction device (11). The three-clutch transmission device for the electric vehicle can be used for the electric vehicle and has the advantages of power gear shifting, short gear shifting time, good gear shifting quality, simple structure, low cost and the like.

Description

A kind of three clutch speed-changing apparatus and electric motor cars that are used for electric motor car

Technical field

The present invention relates to the vehicle technology field, relate in particular to a kind of three clutch speed-changing apparatus and electric motor cars that are used for electric motor car.

Background technique

Electric vehicle development adopts the single reduction gear scheme more, utilizes the governor control characteristics of motor to carry out stepless speed regulation.The single reduction gear scheme is used on small-sized electric car well, because little electric motor car is lower to the relative traditional combustion engine automobile of the requirement of power character.But expand kind and when carrying out the exploitation of intermediate car electric drive system, single-stage deceleration scheme but is difficult to take into account the contradiction of highest speed and max. climb slope carrying out the vehicle seriation; And if adopt traditional multi-speed gear box structure relative complex, and because the motor ratio engine has wideer speed regulating section, automobile industry recognizes that gradually 2 grades or 3 grades of employings are the comparatively ideal schemes of electric motor car exploitation.

At present, the automatic transmission of on automobile, using mainly contains: hydraulic automatic speed variator (AT), automatic mechanical transmission (AMT), ST (CVT) and double-clutch automatic transmission (DCT).Wherein, DCT is one of the most valued automatic transmission at present.It realizes gear shift through the switching of two clutches.Also be not used at present the speed changer of the three-clutch of electric motor car.

Summary of the invention

The technical problem that the present invention solves is to solve the contradiction of electric motor car highest speed and max. climb slope.

In order to overcome the above problems; A kind of three clutch speed-changing apparatuses that are used for electric motor car; Comprise input shaft, K1 clutch, K2 clutch, K3 clutch, 1 grade of gear, 2 grades of gears, 3 grades of gears, output shaft, conducting unit and gear controllers; Said K1 clutch, K2 clutch, K3 clutch link to each other with 1 grade of gear, 2 grades of gears, 3 grades of gears respectively; Gear controller is controlled input shaft automatically and is inserted different gears through different clutches, and output shaft links to each other with power shift gear through conducting unit.

Further, as a kind of preferred, said conducting unit is made up of main reducing gear and differential mechanism, and main reducing gear links to each other with power shift gear, links to each other with output shaft through differential mechanism again.

The invention also discloses a kind of electric motor car, its motor links to each other with wheel through described a kind of three clutch speed-changing apparatuses that are used for electric motor car.

Because three clutch speed variators that adopt, make that electric motor car can automatic speed changing, solved the contradiction of highest speed and max. climb slope, have power shfit, shift time lacks, and property of automatic shft is good, and is simple in structure, low cost and other advantages.

Description of drawings

When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand the present invention better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide further understanding of the present invention; Constitute a part of the present invention; Illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute to improper qualification of the present invention, wherein:

Fig. 1 is a three-clutch speed change gear structural drawing in the embodiment of the invention.

Among the figure, 1, input shaft, 2, the K1 clutch, 3, the K2 clutch, 4, the K3 clutch, 5,1 grades of gears, 6,2 grades of gears, 7,3 grades of gears, 8, main reducing gear, 9, differential mechanism, 10, output shaft, 11, conducting unit.

Embodiment

Followingly embodiments of the invention are described with reference to Fig. 1.

For make above-mentioned purpose, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing and embodiment the present invention done further detailed explanation.

As shown in Figure 1; A kind of three clutch speed-changing apparatuses that are used for electric motor car; Comprise input shaft 1, K1 clutch 2, K2 clutch 3,5,2 grades of gears of 4,1 grade of gear of K3 clutch 6,3 grades of gears 7, output shaft 10, conducting unit 11 and gear controller (not shown)s; Said K1 clutch 2, K2 clutch 3, K3 clutch 4 link to each other with 6,3 grades of gears 7 of 5,2 grades of gears of 1 grade of gear respectively; Gear controller is controlled input shaft 1 automatically and is inserted different gears through different clutches, and output shaft 10 links to each other with power shift gear through conducting unit 11.Said conducting unit 11 is made up of main reducing gear 8 and differential mechanism 9, and main reducing gear 8 links to each other with power shift gear, links to each other with output shaft 10 through differential mechanism 9 again.

Through the clutch K1 that arranges side by side, K2, K3 forms the three-clutch device; Three clutches respectively with 1 grade, 2 grades, 3 grades of input gears link to each other; Thereby only need carry out three combinations between the clutch and separate control automatically, just can realize the switching of three gears.

A kind of electric motor car, its motor links to each other with wheel through above-mentioned three clutch speed-changing apparatuses.

As stated, embodiments of the invention have been carried out explanation at length, but as long as not breaking away from inventive point of the present invention and effect in fact can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within protection scope of the present invention.
