Embodiment Construction

[0031] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0032] In the double clutch transmission described in this invention, the inner input shaft 10 and the outer input shaft 20 are coaxially arranged, and at least a part of the inner input shaft 10 is surrounded by the outer input shaft 20; Arranged in parallel. The inner input shaft 10 is connected to the first clutch disc 72 and the outer input shaft 20 is connected to the second clutch disc 74 .

[0033] Each forward gear driving gear 12, 14, 16, 18, 22, 24 is fixedly connected to two input shafts 10, 20 respectively; each forward gear driven gear and reverse gear driving gear 35 are respectively vacantly sleeved on two countershafts 30, 40 superior.

[0034] The main deceleration driving gears 39, 49 on the two auxiliary shafts are in constant mesh with the main deceleration driven gear 82, and the differential assembly 80 is used as the out...

Abstract

The invention discloses a double-clutch gearbox transmission device for a vehicle. The double-clutch automatic gearbox transmission device comprises an inner input shaft and an outer input shaft which are arranged coaxially, two auxiliary shafts parallel to the two input shafts, a double-clutch and differential assembly, multiple groups of normally engaged gears arranged on each shaft, and multiple groups of synchronizer devices for selecting gears. The double-clutch gearbox transmission device is capable of providing six forward gears and one reverse gear. A reverse gear driven gear is indirectly driven by a reverse gear driving gear connected with a first gear driven gear, the reverse gear transmission ratio is higher, so that the reverse gear safety is higher. The fourth gear and the sixth gear use the same driving gear so that the axial size of the gearbox is effectively reduced. Low gear groups are arranged at the shaft end of a gearbox shaft system, so that the shaft system has higher rigidity, smaller abrasion and longer service life. The gearbox device is featured with simple structure, small axial size, large transmission ratio freedom and so on.

Description

technical field [0001] The invention belongs to the technical field of vehicle (automotive) transmissions, and in particular relates to a dual-clutch automatic transmission transmission device. Background technique [0002] Comfort, handling and high efficiency and economy are all very important performance indicators of vehicles and transmissions. In the application of traditional manual transmissions and automatic transmissions, the above performance aspects are all at the expense of the other. Choosing high handling and high efficiency and economy means low comfort; choosing high comfort means making compromises in handling and economy. [0003] However, the adoption of the new dual-clutch transmission (DualClutchTransmission) can satisfy people's comprehensive demands on the above performance to the greatest extent. Dual-clutch transmissions can provide high efficiency and higher controllability comparable to manual transmissions, and can meet people's needs for vehicle...
