Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of double clutch gearbox structure as shown in Figure 1, comprise gear box casing 25, double clutch, be arranged on the hollow input shaft 2 of gear box casing 25 1 ends, the output shaft 24 that is arranged on gear box casing 25 the other ends, the coaxial solid input shaft 1 that is arranged in the hollow input shaft 2, wherein, the clutch drived disk assy of first clutch 22 is connected with hollow input shaft 2; The clutch drived disk assy of second clutch 23 is connected with solid input shaft 1, the active friction plate of first clutch 22, second clutch 23 is connected on the engine crankshaft, be provided with rigid bearing 26 between hollow input shaft 2 and the solid input shaft 1, be provided with medial support structures 6 in the gear box casing 25, medial support structures 6 is propped up hollow input shaft 2, is provided with a jack shaft 21 that parallels with hollow input shaft 2 in the gear box casing 25.Above-mentioned supporting way to hollow input shaft 2 and solid input shaft 1 can reduce the friction of reversing that causes because of moment of torsion is excessive between hollow input shaft 2 and the solid input shaft 1, the life-span that helps improving input shaft in gearshift procedure.
In the technique scheme, second gear driving gear 3, two fourth gear synchronizers 4 and fourth gear driving gear 5 have been fixedly connected sequentially on the hollow input shaft 2; Reverse driving gear 7, a reverse gear synchronizer 8, one grade of driving gear 9, third speed drive gear 10 and three Five-gear synchronizers 11 have been fixedly connected sequentially on the solid input shaft 1; Be fixedly connected with five grades of driving gears 12 that cooperate with three Five-gear synchronizers 11 on the output shaft 24; Second gear driven gear 20, fourth gear driven gear 19, reverse gear driven gear 16, first speed driven gear 15, third gear driven gear 14 and five grades of driven gears 13 have been fixedly connected sequentially on the jack shaft 21.Be provided with the reverse gear shaft 18 parallel with jack shaft 21 in the gear box casing 25, reverse gear shaft 18 is fixedly connected with idle pulley 17, and this idle pulley 17 is meshed with reverse driving gear 7 and reverse gear driven gear 16.The driving gear that above-mentioned driven gear is all corresponding with it matches.
Introduce working procedure of the present utility model below: when vehicle was in halted state, first clutch 22 all was open in usual with second clutch 23, so the power that motor produces can not passed.
When vehicle was started to walk with one grade, self-clanging gear-shift engaged a reverse gear synchronizer 8 with one grade of driving gear 9, and gear switch is one grade.So as Fig. 2, first clutch 22 keeps off states at this moment, second clutch 23 engages, the power of engine crankshaft output is delivered to solid input shaft 1 through second clutch 23, be delivered to jack shaft 21 through a reverse gear synchronizer 8, one grade of driving gear 9, first speed driven gear 15 then, arrive five grades of driving gears 12 through five grades of driven gears 13 again because five grades of driving gears 12 are fixedly connected on the output shaft 24, so the time power transmit through output shaft 24 through a series of transmission.
Because two fourth gear synchronizers 4 are on hollow input shaft 2, hollow input shaft 2 is connected with first clutch 22, and when vehicle was exercised with one grade, first clutch 22 was in still separated state.When vehicle continue to be exercised, vehicle was during near the shift point of second gear, and automatic shift system is controlled two fourth gear synchronizers 4 and engaged with second gear driving gear 3; When vehicle gave it the gun to the second gear bonding point, first clutch 22 engaged, and second clutch 23 disconnects, and this moment, two clutches were finished switching, and vehicle changes to second gear.As shown in Figure 3, second clutch 23 disconnections this moment, first clutch 22 engages, the transmission of power of engine crankshaft output to hollow input shaft 2 that first clutch 22 is connected on, process is delivered to jack shaft 21 with two fourth gear synchronizers 4, second gear driving gear 3, second gear driven gear 20 that hollow input shaft 2 is fixedly connected, arrive five grades of driving gears 12 through five grades of driven gears 13 again, then through output shaft 24 outputs.
After vehicle entered the second gear enforcement, Study on Control System of Gear Shift for Automatic can be obtained the current running state of vehicle according to relevant sensor signals, and then judged that vehicle is about to enter the gear of operation, if vehicle quickens, then enter third gear, if vehicle deceleration then enters one grade.Control by second clutch 23 with third gear owing to one grade, this moment, this clutch was in separated state, transferring power not, so shift control can be hung gear in advance into next work gear, when vehicle reaches next shift point, first clutch 22 is separated, second clutch 23 engages, finish the switching of two clutches, whole gearshift procedure can be finished.The gearshift procedure of other each gears similarly.As can be known, this novel pair of its power of clutch gearbox must transmit output through output shaft 24 then by single jack shaft 21 transition.
The content that this specification is not described in detail belongs to related domain professional and technical personnel's known prior art.
