Problems solved by technology

However, in the process of dry double clutch processing and assembly, there is a problem that it is difficult to ensure the coaxiality between the spline hub of the I clutch driven disk assembly and the spline hub of the II clutch driven disk assembly and the bearing. How to solve the problem? The centering problem during assembly is a key technical problem to be solved for dry dual clutches

Abstract

The invention discloses two flywheels applied on a dry dual clutch, aiming to overcome the problem of difficult assembly of the dual clutch, which is characterized in that: a flywheel (2) and an intermediate flywheel (5) both are round disks each comprising a wheel rim, a plurality of wheel spokes, and a wheel hub; a plurality of engaging teeth (28) are radially machined on the right end face of the wheel rim of the flywheel (2) for mesh-connecting with the intermediate flywheel. A plurality of through engaging tooth spaces (30) are machined on the circumference of the wheel rim of the intermediate flywheel (5) for mesh-connecting with the engaging teeth (28) of the flywheel (2); the cross sections of the engaging teeth (28) and engaging tooth spaces are in the shapes of isosceles trapezoids or rectangles, and are evenly distributed on the wheel rims. A flange through hole and a bearing hole are respectively arranged on the centers of the wheel hubs of the flywheel (2) and the intermediate flywheel (5), and a flywheel snap ring is arranged on the left end of the bearing hole for restraining the intermediate flywheel (5) from moving along the axial direction. The invention also discloses the dry dual clutch using the two flywheels.

Description

technical field [0001] The present invention relates to two flywheels used on a dry double clutch device and a dry double clutch device using the two flywheels, and more particularly, it relates to two flywheels used on a dry double clutch and an installation A dry dual clutch with two flywheels. Background technique [0002] Automobile dual-clutch automatic transmission (DCT) usually uses two clutches (dual clutches), the transmission gears are arranged separately according to odd and even numbers, and connected to the two clutches respectively, and two gears can be selected to be engaged at the same time during the shifting process. state, one gear is working and the other is waiting, and the shifting process is completed through the alternate switching of the two clutches. DCT combines the advantages of electromechanical automatic transmission (AMT) and hydromechanical automatic transmission (AT), and inherits many advantages of manual transmission, such as high transmis...
