Abstract:
A compounder assembly comprising:an input shaft;an output shaft;a first clutch operable to provide a one-way locking function for coupling said input shaft to said output shaft;a planetary gearset including a sun gear, a ring gear fixed to said output shaft, a carrier fixed to said input shaft, and planet gears supported on said carrier and which are meshed with said sun gear and said ring gear;a brake drum fixed to said sun gear;a band brake operable in a released mode to permit rotation of said brake drum and in a braked mode to prevent rotation of said brake drum;a second clutch disposed between said brake drum and said carrier, said second clutch is operable in a locked mode to provide a one-way clutching function for preventing said carrier from overrunning said brake drum, and said second one-way clutch is further operable in a released mode to permit bi-directional free-wheeling between said brake drum and said carrier; andan actuator for shifting said second clutch into its locked mode and said band brake into its released mode to establish a first speed ratio drive connection between said input shaft and said output shaft, and said actuator is operable for shifting said second clutch into its released mode and said band brake into its braked mode to establish a second speed ratio drive connection between said input shaft and said output shaft.
