Embodiment Construction

[0027] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0028] see figure 1 The double-clutch automatic transmission device that embodiment shows all has following structure:

[0029] The inner input shaft 10 and the outer input shaft 20 are arranged coaxially, and at least a part of the inner input shaft 10 is surrounded by the outer input shaft 20; the first auxiliary shaft 30 and the second auxiliary shaft 40 are arranged parallel to the two input shafts. The inner input shaft 10 is connected to the first clutch disc 72 of the dual clutch 70 and the outer input shaft 20 is connected to the second clutch disc 74 .

[0030] Each forward gear driving gear 12,14,22,24 is respectively connected on two input shafts 10,20, they are non-rotatable with respect to respective input shafts, can adopt spline connection or other forms; Each gear driven gear 32,34 . Rotation is provided on the reverse gear sh...

Abstract

The invention relates to a double-clutch automatic transmission device which structurally comprises internal and external input shafts (10, 20) which are coaxially arranged, an auxiliary shaft (30) and a reverse gear shaft (40) which are parallel to the two input shafts, a double-clutch assembly (70), a differential assembly (50), multiple groups of normally engaged gear trains arranged on all the shafts as well as multiple groups of synchronizer devices (62, 64, 66 and 68) which are used for realizing selection of all gears. The double-clutch automatic transmission device can provide eight forward gears at most and a reverse gear, so that the transmission device has more excellent comfort performance and lower oil consumption. As two groups of optional reduction gear trains are adopted, each gear train can realize two different gears, so that one auxiliary shaft and assemblies thereof can be reduced, and the transmission cost is reduced. The double-clutch automatic transmission device has the characteristics of simple structure, large quantity of gears, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of vehicle (automotive) transmissions, and in particular relates to a double-clutch automatic 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] The dual-clutch automatic transmission can satisfy people's comprehensive demands on the above performances to the greatest extent. However, the existing dual-clutch transmission has a complex structure and high cost, and it is difficult to meet the market demand. Contents of the invention [0004] The purpose of the present invention is...
