補助作動を有する流体継手
Document Type and Number:
Japanese Patent JP4224611
Kind Code:
B2
Abstract:
A supplemental pressurized hydraulic supply (103) provides control of a hydraulic coupling (32a,32b,32c) that normally operates in response to differential rotation between a pair of rotary members (26,28) to provide actuation of a clutch (68) that couples the pair of rotary members. A rotary seal assembly (104) of the supply (103) feeds pressurized hydraulic fluid to the coupling to provide supplemental actuation of the clutch (68) that is normally actuated by hydraulic fluid from a hydraulic pump (48) that operates in response to the differential rotation between the pair of rotary members. In one embodiment, the hydraulic coupling (32a) also includes a differential gear set (36). A further embodiment of the hydraulic coupling (32b) includes a clutch (68) having a pair of clutch packs (69) that can be individually actuated by the supplement pressurized hydraulic fluid supply (103). A further embodiment of the hydraulic coupling (32c) has a pair of rotary members embodied by an annular gear (26) and a rotary member (28) extending completely through the coupling.
