改良したパーキング用ブレーキを有するフレーム回転型油圧モータ
Document Type and Number:
Japanese Patent JP5822512
Kind Code:
B2
Abstract:
A rotary fluid pressure device (20) includes a gerotor gear set (24) having a ring gear (28) and a star gear (30) orbitally moveable about a longitudinal axis (36) relative to the ring gear (28). The star gear (30) includes an annular spacer ring (58) disposed at one end of the star gear (30). A brake pin (60) is moveable along the longitudinal axis (36) into and out of interlocking engagement with the annular spacer ring (58). The brake pin (60) includes an outer surface (62) for engaging an interior surface (66) of the spacer ring (58). The outer surface (62) of the brake pin (60) and the interior surface (66) of the spacer ring (58) are each angled relative to the longitudinal axis (36) to engage each other in a tapered engagement, to generate an axial force along the longitudinal axis (36) to move the brake pin (60) out of engagement with the star gear (30) in response to a torque being applied to the star gear (30).
