ABSTRACT:
A transmission suitable for use in a winch, wire line drum, or other vertical hoisting device is provided with independently actuatable disc clutches for actuating various planetary gear sets to vary the speed through at least three speed ranges. The gear sets and clutches are immersed in oil, and control means are provided to energize the clutches always in sets of two so that only one disc clutch remains disengaged to minimize the viscous drag of the disengaged clutch in the oil. The planetary sets and clutches form the transmission between an input shaft and an output drive assembly. In the preferred embodiment, a final multiple-speed drive assembly is provided to increase the three-speed ratios to six-speed ratios to obtain a wide speed range.
