    • A multi-speed winch (70, 80) is attached to a motor vehicle (200) and is hydraulically powered by the vehicle's power steering system (12) or other hydraulic source innate to the host vehicle (200). The winch operates in either a low-speed, high-torque mode for moving heavy loads, a high-speed, low-torque mode for quickly releasing or retrieving cable (82), a free-spooling mode for manually releasing cable (82), and a brake mode for holding the cable and load at a fixed position. The high-speed mode is enabled by coupling the drive shaft (75) directly to the winch drum (80). The low-speed mode is enabled by coupling the drive shaft (75) to the winch drum (80) through a planetary gear assembly (83a-c, 84). In an alternate embodiment, high-speed mode is enabled by coupling the drive shaft (248) to the winch drum (250) through one of two planetary gear assemblies. Free-spooling mode is achieved by disengaging the drive shaft (248) from the winch drum (250), and brake mode is achieved by engaging both the direct drive coupling (120) and the sun and planet gear arrangement (83a-c, 84). The four operational modes are selected by four different combinations of positions of a direct drive selector handle (134) (which determines the position of the coupling plate) and a gear reduction handle (8) (which determines the position of the locking pin). In an alternative embodiment, the four operational modes are selected by four different combinations of positions of a direct drive solenoid (140) and a gear reduction solenoid (148). A four-way, dual solenoid-operated valve (20) controls the flow of pressurized hydraulic fluid to the winch motor (70).

    • A limited fixed torque slip coupling (10) for connecting rotatable shafts. In one embodiment, a first rotatable member (12) is coupled to a second rotatable member (14) to enable rotation of the first and second rotatable members without substantial relative movement of the members during normal operation when the torque experienced does not exceed a predetermined break-away torque. The coupling (10) of the present invention also enables detection and comparison of the rotational rates of the rotatable members (12, 14) to permit a user to avoid damage to equipment in the event torque greater than that experienced under normal operating conditions is encountered.

    • The specification discloses a fluid coupling (10) for connecting rotatable shafts (38, 42). In one embodiment, rotation of an output shaft (38) is transferred to a drive shaft (42) by a pair of opposed rotatable rings (14, 16) having interleaved fins (98, 100, 102, 104; 134, 136, 138, 140, 142). The interleaved fins (98, 100, 102, 104; 134, 136, 138, 140, 142) provide fluid filled chambers (200, 202, 204) and relative movement of the fins (98, 100, 102, 104; 134, 136, 138, 140, 142) compresses the fluid and increases the ability of the fluid to transfer torque.
