Abstract

The prime mover of a power train for use in a motor vehicle normally drives a flywheel by way of a first engageable/disengageable clutch, and the flywheel drives the rotary input member of an automated change-speed transmission assembly by way of a second engageable/disengageable clutch. At least one first auxiliary aggregate (such as the pump of a power steering unit) can receive torque directly from the prime mover, and at least one second auxiliary aggregate (such as the compressor of an air conditioning system) can receive torque from the input member of the transmission assembly or from the prime mover. The rotary output member of the transmission assembly can receive torque from a continuously variable transmission which receives torque from the input member by way of a planetary, or from a planetary which receives torque from a continuously variable transmission. The internal gear of the planetary can be arrested by a stationary brake to thus interrupt the transmission of torque to the output member.
