On this basis, at arranged outside one housing 1 of double clutch 3, formed thus with one-piece element, ensure the compact structure of whole product, stable performance.
In order to realize by hydraulic system to control the open and-shut mode of double clutch, this programme arranges odd number gear clutch hydraulic pressure control unit and even number gear clutch hydraulic pressure control unit respectively in the rear and front end of double clutch 3.
Odd number gear clutch hydraulic pressure control unit is arranged on the front end of double clutch, and odd number gear clutch is combined in double clutch, controls the opening and closing of the odd number gear clutch being in normally off with this.

The gearshift principle of the electronic pair of clutch control device formed thus is as follows:
1, the open and-shut mode of double clutch is controlled by hydraulic system, by controlling the state of the solenoid valve on hydraulic valve, can complete the handoff procedure of double clutch.
Odd number gear clutch is normally closed, and even number gear clutch often opens.Gearbox control is not when powering on, odd number gear clutch is in closed state, even number gear clutch is in separated state, synchronizer mediates simultaneously, after gearbox control powers on, synchronizer and first gear engage, and at this moment gearbox enters a gear state (see Fig. 2).
2, when odd number gear changes to even number gear, synchronizer position can not be moved, and is still in the state engaged with first gear.Now, the solenoid valve controlling odd number gear clutch can first be opened, pressure in hydraulic circuit raises, promote odd number gear piston to move, thus piston driving odd number gear clutch lever moves, lever tightly withstands odd number gear clutch plate, makes odd number keep off clutch separation (referring to clutch even number gear schematic diagram sectional drawing A).After odd number gear clutch is opened, even number gear clutch comes into action, this principle is identical with the operating principle of odd number gear clutch.Unique difference is odd number gear clutch is normally closed, and even number gear clutch often opens, so the movement of lever can make two clutches have opposite effect effect.After gearbox enters two gears, along with rotating speed rises, synchronizer position first can move to neutral position, when when controller, rotating speed continuation rising judges that gearbox may enter three gears time, synchronizer move and and output gear joint, be that two gears change three gears and prepare (see Fig. 3).
3, when even number gear changes odd number gear, synchronizer position can not be moved, and at this time synchronizer has been in the state engaged with output gear.Now, even number gear clutch can first be separated, and odd number gear clutch closes again afterwards.The identical when working principle of solenoid valve and a gear shift into second.The solenoid valve controlling even number gear clutch and odd number gear clutch can be successively closed, thus the pressure in hydraulic circuit is reduced, and piston returns to initial position.
The electronic pair of clutch control device formed thus, its working procedure is as follows:
When on automobile suspension, 1 gear starting travels, 1. the clutch controlling the input of odd number gear is connected, and the solid input shaft that connection odd number is kept off rotates, and 1 gear synchronizer, 1 automatically and on bottom gear output shaft keeps off gears meshing, realizes linking with bottom gear output shaft.Power transmission line, as shown in solid line and arrow in Fig. 2, to be combined with synchronizer at the end of low-speed output shaft and directly to spread out of power by output shaft again.
While 1 gear synchronizer and 1 gear gear are meshed, 2 gear synchronizers are also meshed with 2 gear gears under the control of electrically-controlled component, are in work armed state.For the power transmission route of 2 gears, after speed changer is linked into 1 gear, 2. the clutch controlling even number gear input shaft is be separated, input shaft now connects the sleeve (hollow) of even number gear although also can rotate under the drive of 2 gear gears, but it is at the pinion rotation that followed by other odd numbers gear completely, the output of any power, is not only for ensuing upshift is prepared in advance.Therefore the input shaft of even number gear also would not cause interference to the power that odd number keeps off input shaft, the output shaft of top gear also can follow rotation, but be in idling conditions equally, without any the output of power, so occur mutually to interfere without any power on Power output.
When speed changer enters 2 gear, when stepping on while 1 gear clutch exits 1 gear, clutch 2 connects, hang up 2 gears as Fig. 3 schematic diagram, shown in middle solid line and arrow, meanwhile, 3 gears combine as shown in solid line and arrow in Fig. 2 again in advance, continuous print like this carries out work, makes speed changer completely very close to each other when entering gear and plucking gear.So always there are 2 gears to be combine in the working procedure of DCT speed changer, one works, and another is then that next step is ready.Control the clutch of even number gear under the control of ECU (Electrical Control Unit), be combined with the clutch end of motor, the control odd number gear clutch of input shaft and the output terminal of motor disconnect, just complete the powershift of input shaft, in this process, two clutches carry out completely continuously, and again can as traditional single clutch speed changer, when gear shift, the clutch end of clutch and motor disconnects, and there will be the power interruption phenomenon of long period.Completing two gear powershifts simultaneously, the synchronizers controlling three gears also can under the control of electric-controlled parts, keeps off speed-change gear box and engage, make the driving gear of three gears standby with three.
