A starter generator system comprising an engine driving a first belt and engaged with a second belt through a one-way clutch, a starter generator configured to be driven by the engine through the second belt or to drive the engine through the second belt according to an engine condition, and an accessory engaged with the second belt through an accessory clutch, the accessory drivable by the first belt or the second belt.

Accessory belt drive system with multiple ratios and torque reversal

An isolating decoupler comprising a shaft, a pulley having an inner surface, a pulley rotationally engaged about the shaft, a torsion spring having a first section having a major diameter and a second section having a minor diameter, the major diameter is greater than the minor diameter, the torsion spring engaged with the shaft, a wrap spring having an outer diameter greater than an inner surface diameter, the wrap spring frictionally engaging the inner surface, the wrap spring loaded in an unwinding direction, the torsion spring having an end fixedly connected to the wrap spring, the torsion spring loaded in an unwinding direction whereby the diameter of each coil of the torsion spring decreases in a progressive sequence as a load increases, the first section is disposed radially inboard of the wrap spring such that the first section moves radially outward to clamp the wrap spring during a load condition.

Isolating decoupler

An isolating decoupler comprising a shaft, a pulley having a belt bearing portion, a one way clutch, a torsion spring, the torsion spring engaged between the pulley and the one-way clutch, and a single bearing disposed between the shaft and the pulley, the bearing comprising a radial centerline, the radial centerline aligned with a mid-line of the belt bearing portion.

An isolating decoupler comprising a shaft, a pulley journalled to the shaft, a torsion spring, the torsion spring comprising a flat surface planar in a plane normal to the rotation axis A-A on each end of the torsion spring, a one-way clutch engaged between the torsion spring and the shaft, a weld bead joining a torsion spring end to the one-way clutch, and a weld bead joining the other torsion spring end to the pulley.
