Fast gear 52 is arranged on differential mechanism 60.Parking gear 53 is additionally provided between final gear 51 and driving gear set.
In summary, in the present invention, by setting idler shaft 25, idle wheel 33 and reversing-gear synchronizer 45, and idle pulley is made
Axle 25 is coaxially disposed with output shaft 24, can make idle wheel 33 while power transmission is undertaken, additionally it is possible to by same with reverse gear
Step device 45 is engaged, and plays a part of back gear.When reversing-gear synchronizer 45 is combined with idle wheel 33, on second clutch 12
Power, by the first idler gear 31 and idle wheel 33, can be directly entered in output shaft 24, and transmitted via differential mechanism 60
To wheel, vehicle is driven to carry out reversing operation.Because this is in the speed changer, idle wheel 33 assume responsibility for intermediate drive gear and fall
Two effects of shelves gear, therefore, the laying mode structure is relatively simple, and laying is more compact, and because the power of reverse gear passes
Pass wheel footpath be pass sequentially through second clutch 12, the 3rd output shaft 24, the first idler gear 31, idler shaft 25, output shaft 24 and
Train of reduction gears 50 is then transferred to differential mechanism 60, and therefore, the power transfer path is shorter, improves transmission efficiency.Therefore,
The automatic transmission structure is simple, lays compact, the bang path of power when can reduce reverse gear, lifts transmission efficiency.
Present invention also offers a kind of vehicle, and the vehicle includes above-mentioned double-clutch automatic gearbox, on the vehicle
