A front end accessory drive (FEAD) for a military vehicle. The FEAD includes a first belt, a second belt, multiple accessories, an electric motor-generator, at least one other accessory, and a sprag clutch. The accessories and the electric motor-generator are coupled with the first belt. The at least one other accessory, the first belt, and the second belt are coupled with the sprag clutch. The second belt is configured to couple with an output shaft of an engine of the military vehicle and be driven by the output shaft of the engine to drive the sprag clutch. The sprag clutch is thereby configured to drive the at least one other accessory and the first belt, and the first belt is thereby configured to drive the plurality of accessories, and the electric motor-generator.

The embodiments disclose a method including separating kinetic speed from energy using a transmission platform, directing energy in the kinetic form at a predetermined speed from 0 to 100%, employing the transmission platform with fewer pieces to increase overall efficiency at a lower cost to produce, and integrating the transmission platform with combustion engines and electric motors to achieve more efficiency and greater performance.

A decoupler pulley is provided for automotive belt-driven accessory drives, which utilizes a single torsion coil spring that provides torsional resiliency and overrunning functionality. As the torsion spring expands it increasingly pinches a bushing disposed between a radially expansible hub and pulley to thereby provide proportional damping.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.

An electric power take-off system for mounting to a truck body to complement an existing power-take-off system powered by an internal combustion engine. The system includes a motor, a battery for providing electrical power to the motor, a fluid reservoir, a pump for pumping fluid through at least one hose from the fluid reservoir to at least one truck function and for return of the fluid to the reservoir. The system also includes a system interlock rendering inoperable the electric power-take-off system when the internal combustion engine is in operation and a motor controller in communication with the motor for controlling the power output of the motor. The system also includes a charging unit for charging of the battery and a data management system operable to collect data.

A powertrain has an internal combustion engine provided with an accessory transmission that includes a first pulley connected to a crankshaft of the engine, a second pulley connected to a shaft of an electric machine, and a belt connecting the first and the second pulleys to each other to rotate in the same direction of rotation (R). The electric machine is operated to supply an active torque to the second pulley during start-up of the internal combustion engine by means of a starter motor.
