Problems solved by technology

The dual-clutch automatic transmission itself includes two clutches. The two clutches respectively drive the driving gear of the corresponding gear to rotate through an input shaft, but the two clutches must be used alternately. When any one of the clutches is damaged, the entire automatic transmission will be broken. Not working properly, this will cause a lot of inconvenience, especially for vehicles where one of the clutches is damaged in the middle of the road, the vehicle can only be parked and waited for repairs, delaying time

Embodiment Construction

[0061] figure 1 It is a structural schematic diagram of a dual-clutch automatic transmission according to an embodiment of the present invention. Dual clutch automatic transmissions generally may include a housing (not shown) that at least partially encloses the gearing of the transmission. The gear arrangement may include various shafts, intermeshing co-planar gear sets, dual clutch assemblies, and selectively engageable synchronizers, as will be described herein.

[0062] The dual clutch automatic transmission according to the present invention may include a first input shaft 1 and a second input shaft 2 arranged coaxially, and a first output shaft 3 and a second output shaft 4 arranged in parallel and separated. The second input shaft 2 is a hollow shaft, which is sleeved on the first input shaft 1 and allows relative rotation between the first input shaft 1 and the second input shaft 2 .

[0063] The dual clutch assembly of the present invention may comprise a concentric...

Abstract

The invention provides a double-clutch automatic transmission which comprises a first clutch, a second clutch, a first input shaft connected with the first clutch and a second input shaft connected with the second clutch. The second input shaft is of a hollow structure and is coaxially sleeved outside the first input shaft. The double-clutch automatic transmission further comprises a connecting mechanism. The connecting mechanism is used for selectively connecting the first input shaft and the second input shaft so as to allow the first input shaft and the second input shaft to rotate synchronously. When one optional clutch is damaged, the double-clutch automatic transmission can operate normally by the aid of the another good clutch, time delay of a driver can be avoided under the circumstance that the clutch is damaged, and unnecessary loss can be prevented.

Description

technical field [0001] The invention relates to the field of automobile transmissions, in particular to a dual-clutch automatic transmission. Background technique [0002] With the continuous reduction of non-renewable oil resources and the increasing pollution of the environment by vehicle exhaust, countries have become more and more strict on the fuel consumption and emission regulations of vehicles. The transmission efficiency of the transmission system has a greater impact on the fuel consumption of automobiles, and the development of efficient and energy-saving automatic transmissions has become the focus of research and development by domestic and foreign automobile companies. Traditional automatic transmissions (AT) and continuously variable automatic transmissions (CVT) use hydraulic torque converters with low transmission efficiency, and the highest comprehensive transmission efficiency can only reach about 85%, while the transmission efficiency of dual-clutch autom...
