Abstract
The invention discloses a double-clutch device, which comprises a double clutch, a double clutch shell and a clutch oil sealing cover board, wherein the clutch oil sealing cover board is used for packaging the double clutch into the double clutch shell. Rotary shafts used for supporting the double clutch to rotate at two ends of the double clutch are respectively installed in the rotary shaft seats of the clutch oil sealing cover board and the double clutch shell. A deep groove ball bearing is also arranged between each rotary shaft and each rotary shaft seat, and the inner ring and the outer ring of the deep groove ball bearing are respectively in interference fitting with each rotary shaft and each rotary shaft seat. A snap ring for preventing each deep groove ball bearing from moving along an axial direction is also bucked at each rotary shaft through a groove of the rotary shaft. As two deep groove ball bearings are arranged at the front end and the rear end of the clutch, the radial location problem of the double clutch in a gearbox is effectively solved. Due to the arrangement of the snap rings, the axial movement of the double clutch is effectively limited, the double clutch cannot have larger axial movement and radial runout during high-speed running, and the stable running of the double clutch is kept.
