Integrated front end accessory drive system

摘要

A system for integrating together all the engine driven accessories on a typical automotive engine such that all the basic engine auxiliaries and secondary chassis related accessories are mounted in a compact and rigid assembly. The driving means for the secondary accessories is typically but not restricted to a single Multi-rib V belt driven by a pulley or torsional damper mounted to the front extension of the crankshaft. The auxiliaries and accessories are built into or mounted rigidly to an integrated housing. The integrated housing is mounted to a single surface of the engine block giving the strength and rigidity needed to carry the loads and offering the best accuracy for the location of the accessories to the crankshaft and to each other for best belt life and minimum noise from the belt and pulleys and engine forcing frequencies. The single housing also offers the ability to allow pre-assembly of the whole front end assembly drive (FEAD) package for the subsequent modular assembly to the rest of the engine.
