A hydraulic coupling (32,32a) includes a lock (204) for selectively preventing the level of torque transmitted from a coupling casing (34) to a pair of rotary members (26,28) from affecting torque transfer between the rotary members. The coupling (32) also includes an adjuster (216) for adjusting resistance of fluid flow from a hydraulic pump (48) through ports of the coupling to control coupling of the pair of rotary members (26,28) to each other. One embodiment of the coupling (32) operates in a supercharged pumping manner, while another embodiment of the coupling (32a) pumps the fluid through a clutch actuating piston (72) of the coupling.

A coupling for use with a vehicle drivetrain to rotatively couple a pair of rotary members about a rotational axis, the coupling comprising: a casing of hollow construction that is rotatively driven about the rotational axis; a bevel type planetary gear set located within the casing and having a pair of bevel side gears respectively connected to the pair of rotary members as well as having a carrier that is rotatable with the casing and has bevel planet gears meshed with the side gears connected to both rotary members; a clutch that is actuatable to connect the casing and one of the rotary members; the planetary gear set upon transfer of torque from the rotating casing through the planetary gear set to the pair of rotary members forcing the side gears thereof away from each other to actuate the clutch and connect the pair of rotary members for torque transfer therebetween at a level that increases with increased torque transfer from the rotating casing to the rotary members; and a lock for selectively preventing the planetary gear set from forcing the side gears thereof away from each other to actuate the clutch such that the extent of the torque transfer from the rotating casing to the pair of rotary members does not affect torque transfer between the pair of rotary members.
