Dual clutch device for vehicle

Abstract

The present invention provides a dual clutch device for a vehicle, which is applied to a vehicle and provided with two clutch packs. The dual clutch device for a vehicle according to an embodiment ofthe present invention: has a structure in which a first carrier and a second carrier operate as input members, and a first driven plate disposed inside a first clutch and a second driven plate disposed inside the second carrier operate as output members; and comprises an operation unit which is mounted to a carrier hub, and disposed outside a first piston and in a direction opposite to the direction in which a drive plate is disposed, so as to operate first and second clutch packs by selectively moving the first piston and a second piston in the direction in which the drive plate is disposed.

Description

technical field [0001] The invention relates to a dual clutch arrangement for a vehicle. More specifically, the invention relates to a dual clutch arrangement comprising two clutch packs. Background technique [0002] Generally, a dual clutch transmission (DCT) performs shifting through a handover control that cross-controls two clutches during a shift. For example, in a dual clutch transmission, stages 1, 3 and 5 are connected to a first clutch and stages 2, 4 and 6 are connected to a second clutch. [0003] In other words, when there is only one clutch, if the third gear is inserted, only that clutch is engaged to the third gear, but in a dual clutch transmission, the clutch is also engaged to the second and third gears of the upper and lower stages in the standby state. Four gears. Therefore, when shifting from third stage to second or fourth stage, the clutch is immediately connected to the second or fourth stage gear, resulting in a smoother shift. The DCT can impro...

Problems solved by technology

[0004] In order to improve the mountability of the transmission, this DCT needs to have the minimum length, and it is necessary to reduce the assembly process and reduce the manufacturing cost by constructing a simple structure, but there is a problem that it is not sufficiently satisfactory

[0005] In addition, conventional dual clutch devices are formed by the structure in which each piston operates each clutch pack operated by supply control of oil, since a compensation chamber should also be provided along with a pressure chamber to properly maintain the oil operating on each piston pressure, there is also the problem of complex layout in the narrow interior space
