Abstract
Abstract A drive installation including two driving engines and a transmission having an input and an output shaft. The first driving engine is connected to the input shaft by way of an engageable clutch; such as a one-way clutch or a clam clutch. The second driving engine is connected to both the input shaft of the transmission by way of a first engageable coupling and to the output shaft of the transmission by way of a second engageable coupling. The transmission is operable to selectively connect either engine or both engines for driving the output of the transmission.
