Hydraulic clutch system with flywheel

摘要

A flywheel (FW) includes a front cover as a first mass member (102), an inner plate as a second mass member (104), and a coiled spring as a damper member (106) which is interposed between the first and second mass members. A clutch or a clutch body (108) is disposed so as to be connectible with and disconnectible from the inner Plate (104) by hydraulic pressures (P0,P1). The front cover (102) and the inner plate (104) are united through a friction plate as coupling means (110) by the hydraulic pressures (P0,P1) for connecting and disconnecting the clutch (108). Thus, the first and second mass members (102,104) can be united by the simple construction of low cost. Furthermore the uniting operation, inclusive of its synchronization with the control of the clutch body (108), can be precisely controlled. <IMAGE>
