ISOLATOR FOR USE WITH ENGINE THAT IS ASSISTED OR STARTED BY AN MGU OR A MOTOR THROUGH AN ENDLESS DRIVE MEMBER

摘要

In an aspect the invention is directed to an isolator comprising a driver that is connectable with a shaft of a device, a rotary drive member that is engageable with an endless drive member; and a first isolation spring and a second isolation spring. The first and second isolation springs are positioned such that during rotation of the driver in a first direction torque is transferred from the driver to the first rotary drive member through the first isolation spring and not through the second isolation spring, and such that during rotation of the first rotary drive member in the first direction torque is transferred from the first rotary drive member to the driver through the second isolation spring and not through the first isolation spring.
