A dry double clutch

Abstract

The invention discloses a dry dual clutch. The dry dual clutch comprises a second input shaft coaxial with a first input shaft; the first clutch comprises a first pressure plate and a first driven plate assembly positioned between a first engine flywheel and the first pressure plate, wherein the first driven plate assembly is connected with the first input shaft by a spline; the second clutch comprises a second pressure plate and a second driven plate assembly positioned between a second engine flywheel and the second pressure plate, wherein the second driven plate assembly is connected with the second input shaft by a spline; the first engine flywheel and the second engine flywheel are fixedly connected through a transition shaft; the first pressure plate is controlled by a first clutch operating mechanism; and the second pressure plate is controlled by a second clutch operating mechanism. Mutual independence of two clutch structures of the dual clutch is realized, so that driven plates are more convenient to replace and maintain. The clutch structures are simplified, and the axial size is reduced. In addition, the dual clutch and the operating mechanisms thereof realize integration, and the integration degree of the dual clutch is improved.

Description

Technical field [0001] The invention relates to a double clutch, in particular to a dry double clutch. technical background [0002] Dual clutch transmission, namely DCT (DualClutch Transmission), can use the characteristics of two clutches to enable the vehicle to automatically select gears without power interruption, that is, to realize the automatic transmission of the gearbox by switching between the two clutches. Control not only makes the driving of the car easier, but also effectively improves the comfort, power and safety of the car. The dual clutch in the dual clutch transmission is responsible for the important functions of gear shifting, starting control, power transmission, torsional vibration reduction, overload protection, etc., and is a key component of the dual clutch transmission system. Due to the simple structure of the dry clutch, high transmission efficiency, and low cost, the dual clutches in the dual clutch transmission mostly adopt the form of dry dual cl...

Problems solved by technology

[0003] The utility model patent with the Chinese patent number ZL200920288970 discloses a dry double clutch. Although the dry double clutch realizes that the clutch coupling force is not transmitted to the engine and avoids damage to the engine, its dual clutch and clutch control The mechanism is separated, and the integration is not realized, so that the axial length of the part of the double clutch belt actuator is too large, resulting in the length of the input shaft of the transmission being too long and difficult to process

In addition, the driven disc assembly of the dry dual clutch is a vulnerable part, which requires frequent maintenance and replacement. This structure also makes the maintenance of the dual clutch difficult. When the driven disc needs to be replaced, the entire clutch must be disassembled Parts can only be replaced, which is not conducive to the commercialization of dry dual clutches
