US Patent 10385949 Shift on the fly transmission

A shift on the fly transmission is provided. The shift on the fly transmission includes a continuously variable transmission portion, a discrete transmission portion, at least one input shaft and a disconnect clutch. The continuously variable transmission portion is operationally coupled to receive torque from an engine. The discrete transmission portion includes a gear assembly. The at least one input shaft is operationally coupled to an output of the continuously variable transmission portion. The disconnect clutch operationally couples the at least one input shaft to the discrete transmission portion. The disconnect clutch is further configured to selectively decouple torque from the at least one input shaft to the discrete transmission portion during a range ratio shift of the discrete transmission portion.
