Device 23 and second clutch 12 are disassembled, beneficial to the replacing of consumable accessory (friction plate).Moreover, only pass through two pairs in every gear transmission
Gear and a clutch, drive path is succinct, therefore the speed changer structure is simple, transmission efficiency.
Often close the double shift transmissions 100 of electric vehicle of clutch according to the band of the present invention, second clutch 12 for often close from
Clutch, in the case of not fuel feeding, speed changer is a gear.
As shown in Fig. 2 according to one embodiment of present invention, second clutch 12 is the thrust by diaphragm spring 47
Pressure is provided to friction plate group.Under not oil-filled state, diaphragm spring 47 is that fulcrum compresses platen 46 with bracing ring 48, now film
Flat spring 47 close to being driven plain, platen 46 make friction plate group (inner attrition piece 43, outer steel disc 44, the outer stress of steel disc jump ring 45, now
Speed changer is in 1 gear；Under oil-filled state, hydraulic oil enters clutch plunger 39, first annular sealing ring from oil-feed oil duct 36
37th, the balancing gate pit that the second O-ring seal 42 and clutch hub 35 are formed, clutch plunger 39 is then promoted to left movement, from
Clutch piston 39 promotes diaphragm spring 47, and the radial section of diaphragm spring 47 is fulcrum with bracing ring 48, and diaphragm spring 47 is in
Inverted cone shape, platen 46 move right, and normal pressure suffered by friction plate group reduces, and now clutch is gradually disengaged.
Herein it should be noted that according to one embodiment of present invention, second clutch 12 and first clutch 23
Structure can be different, as shown in figure 4, first clutch 23 includes：Clutch hub 351, it is sequentially arranged at clutch hub 351
First annular sealing ring 371, clutch plunger 391, clutch retraction springs 401, the return spring jump ring 411 of inner side, and
Inner attrition piece 431, outer steel disc 441, outer steel disc jump ring 451, formed with clutch oil-feed oil duct 361 and cold on clutch hub 351
But oil duct 381, clutch plunger 391 are provided with the second annular type sealing ring 421.Wherein clutch plunger 391 and clutch hub
351 cooperatively form the balancing gate pit of clutch, and the first annular O-ring seal 421 of sealing ring 371 and second is in clutch plunger 391
Oil leak is prevented during motion, when oil pressure reduces, clutch retraction springs 401 make piston return to initial position, its China and foreign countries' steel disc card
Spring 451 limits the displacement of friction plate group, and wherein return spring jump ring 411 limits the displacement of return spring.
It is understood that although first clutch 23 uses different structures, second clutch from second clutch
12 use above-mentioned structure, it is possible to achieve when not having oil pressure, second clutch 12 still combines, and now speed changer is in one
Gear.
According to one embodiment of present invention, the double shift transmissions 100 of the normal electric vehicle for closing clutch of band further comprise
Spline 20 is connected, connection spline 20 is connected between the first driven gear 19 and first clutch 23.

Pad 43 and the spline fitted for being connected spline 20, wherein clutch hub 35 are connected by the second slip flat key 22 with output shaft 16.
Thus, it is possible to improve the reliability of first clutch 23, operating efficiency is improved.
According to one embodiment of present invention, the friction plate structure and size of second clutch 12 and first clutch 23
It is identical, thus, it is easy to the processing and manufacturing and replacing of friction plate, the second driving gear 8 closes on the side of second clutch 12 and is provided with
Second driving gear epitaxy part 9, the second driving gear epitaxy part 9 are connected with second clutch 12.Thus, it is possible to improve second from
The reliability of clutch 12.Further, according to one embodiment of present invention, the inner attrition piece 43 and second of second clutch 12
The spline fitted of driving gear epitaxy part 9, clutch hub 35 are connected by the first slip flat key 11 with input shaft 7.
It should be noted that the double shift transmissions of electric vehicle that band according to an embodiment of the invention often closes clutch are divided into
Two gears：
During one gear：Second clutch 12 is worked, and power is passed to flexible disk 3 by motor 1 by spline, and flexible disk 3 is led to again
Cross spline and pass to input shaft 7, then second clutch 12 is passed to by the first slip flat key 11, second clutch 12 passes power
The second driving gear epitaxy part 9 is passed, power is passed to the second driven gear 14, the second driven tooth by the second driving gear 8 again
Wheel 14 is set to duplicate gear with output gear 15 thereon, and power is passed to main reducing gear and differential mechanism by output gear 15
Assembly 18 exports.
During two gears：First clutch 23 works, and power passes to the first driving gear 6 from input shaft 7 via flat key 4, the
One driving gear 6 passes to the first driven gear 19, and power is passed to first by the first driven gear 19 via connection spline 20
Power is passed to output shaft 16 by clutch 23, first clutch 23 via the second slip flat key 22, and output shaft 16 passes through second
Power is passed to output gear 15 by flat key 17, and power is passed to main reducing gear to output gear 15 and differential assembly 18 is defeated
Go out.
The double shift transmissions 100 of electric vehicle of clutch are often closed according to the band of the present invention, often gear transmission only passes through two pairs
Gear and a clutch, drive path is succinct, therefore the speed changer structure is simple, transmission efficiency.
