Document Type and Number:
Japanese Patent JPH09501219
Kind Code:
A
Abstract:
A vehicle drivetrain differential (22) driven by a rotary drive member (24) rotatively drives a pair of rotary members (26, 28) and includes a housing (30) for containing hydraulic fluid and in which a hydraulic coupling (32) is received. A casing (34) of the hydraulic coupling has a ring gear (44) rotatively driven by the rotary drive member (24). A planetary gear set (36) of the bevel gear type is located within the casing (34) and includes a pair of bevel gears (124, 126) having associated spline connections (128, 130) to the pair of rotary members 926, 28), and the planetary gear set also includes planet gears (132) that revolve with the casing (34) and are meshed with both bevel gears to provide a differential gear action. A fluid inlet (58) and an outlet port (78) of the casing are provided with a gerotor type pump (48) provides pumping of the hydraulic fluid into and out of the casing. A control valve (80) opens and closes the outlet port (78) in response to the relative rotation between the pair of rotary members to control operation of the pump as a brake in coupling the pair of rotary members (26, 28) to each other.
