Claims18
A system, comprising:
- a front end accessory drive system comprising a plurality of components including a two-speed device, wherein the two-speed device comprises an input pulley configured to receive an input belt configured to extend around input pulleys of one or more of the plurality of components, and wherein the two-speed device comprises an output pulley configured to receive an output belt configured to extend around a pulley of an alternator, a generator, or an output pulley of a component of the plurality of components, wherein the input belt is the only input device of the front end accessory device system and extends around a crankshaft pulley.
A front end accessory drive system, comprising:
- a two speed device comprising an input pulley and an output pulley, wherein the input pulley rotates via energy provided via a first belt extending around pulleys of a crankshaft and a plurality of components of the front end accessory drive system, and wherein the output pulley rotates a second belt configured to rotate a belt-integrated starter/generator pulley, an alternator, or a component of the front end accessory drive system, and wherein the two-speed device is physically coupled to a mount of the front end accessory drive system via a plurality of bolts.
A system, comprising:
- an engine comprising a crankshaft;
- an accessory drive system comprising a plurality of components, wherein a first set of the plurality of components is driven via an input belt extending around pulleys thereof, the input belt extending around a crankshaft pulley of the crankshaft;
- and
- an off-axis two speed device mounted to a bracket of the accessory drive system via a plurality of bolts misaligned with axes of the plurality of components, wherein the off-axis two speed device comprises an input pulley around which the input belt extends and an output pulley around which an output belt extends.
