During DCT work, vehicle is earlier with certain gear operation, electrical control unit of automatic transmission (TCU) is judged next gear that is about to the work of entering according to the signal of related sensor, because of this gear clutch separation transferring power not also,, mesh this gear in advance so instruction hydraulic control solenoid valve is controlled gearshift actuator very easily, when vehicle operating reaches shifting points, only the clutch separation that need will work simultaneously with another clutch, then makes automobile travel with next gear.In shift process, the power of motor constantly is passed to wheel all the time, so the shift process of finishing like this is a power gear shifting.Vehicle has been realized the power gear shifting process, will improve shifting comfort greatly, guarantees that also vehicle has good and economic simultaneously, and aspects such as vehicle oil consumption and discharging are made moderate progress.
The model utility content:
The purpose of this utility model is to provide a kind of double-clutch automatic transmission structure, mates preposition rear-guard vehicle, has to guarantee that vehicle obtains good power character, Economy and shifting comfort, the advantage of agility.
The technical solution of the utility model is achieved in that a kind of double-clutch automatic transmission structure, and it is characterized in that: speed changer keeps off input shaft by odd number, even number retaining input shaft, and jack shaft, idler shaft and output shaft, each keeps off gear and synchronizer is formed; Wherein odd number retaining input shaft links to each other with even number retaining clutch with odd number retaining clutch by spline respectively with even number retaining input shaft; Even number retaining input shaft is a hollow shaft, and jack shaft links to each other with odd number retaining input shaft with even number retaining input shaft respectively by each grade gear, and jack shaft passes through deceleration driving gear, and the deceleration driven gear links to each other with output shaft; Corresponding gear on idle pulley on the idler shaft and the even number retaining input shaft links to each other with the corresponding gear on the jack shaft.
Described speed changer connects oil pump, pressure lubrication cooling system and parking braking system; To be double clutch pass to odd number input shaft or even number input shaft with the moment of torsion of motor to power transmission line, back odd number even number input shaft by each retaining gear transmission to jack shaft, the deceleration driven gear, deceleration driving gear is delivered to output shaft.
Good effect of the present utility model is to have to guarantee that vehicle obtains good power character, Economy and shifting comfort, the advantage of agility.
