摘要:
In a twin clutch device used in an engine transmission, there are coaxially and adjacently arranged a first disk clutch and a second disk clutch of a hydraulic pressure type that displace a pressing member in an axial direction with externally supplied hydraulic pressure to exert a predetermined engagement force; and the first disk clutch and the second disk clutch respectively have: an engagement side hydraulic chamber that gives the pressing member a pressing force towards a clutch engagement side; and a pressure compensation hydraulic chamber that gives the pressing member a pressing force towards a clutch disengagement side to compensate a pressure of a returning action thereof. Furthermore in this twin clutch device, a plurality of pipes are internally and externally superposed and inserted into a main shaft connected to the first disk clutch and the second disk clutch, and each of a plurality of spaces within the main shaft divided by these pipes serves as an in-shaft oil passage that communicates with any one of the engagement side hydraulic chamber or the pressure compensation hydraulic chamber.
